    Superior mesenteric artery syndrome is obstruction of the third portion of the duodenum by compression between the abdominal aorta and superior mesenteric artery. Pediatric orthopedists are familiar with this entity, as the association between superior mesenteric artery syndrome and spinal fusion or body casting has been well established. However, patients with spinal deformities usually experience superior mesenteric artery syndrome after orthopedic intervention, with rates after corrective spinal surgery reported between 0.5% and 2.4%. Symptoms of superior mesenteric artery syndrome typically include nausea, bilious emesis, abdominal pain, early satiety, and anorexia. Initial treatment focuses on gastric decompression and maintaining euvolemia and electrolyte balance. The patient should receive enteral nutrition via nasojejunal tube or parenteral nutrition to allow for weight gain and subsequent resolution of the obstruction. The superior mesenteric artery takes off from the duodenum at an angle of 45 degrees to 60 degrees in normal individuals. The third portion of the duodenum is suspended between these vessels by the ligament of Treitz. Any variation in this relationship that decreases the arteriomesenteric angle may induce obstruction. Specifically, lumbar hyperextension or hyperlordosis can traction the mesentery and vessels. Only 2 cases of superior mesenteric artery syndrome in patients with sagittal plane spinal deformity have been described in the literature. In patients with concomitant superior mesenteric artery syndrome and spinal deformity, correction of the deformity may help alleviate the obstruction and result in faster recovery. The contribution of spinal column deformity to the arteriomesenteric angle should not be overlooked. PMID:20608618

    Three patients developed signs of a unilateral cervical cord lesion 6 to 36 h after the acute onset of severe cervico-brachial pain. The neurological deficit progressed over 6 to 18 h. On the painful side a central Horner's syndrome, a hemiparesis with plegia of the hand, and a slight pallhypaesthesia were found. On the opposite side thermhypaesthesia and hypalgesia were noted with a level at the dermatome C5 or C6. T2-weighted MR images revealed in one patient a small area of increased signal intensity restricted to one half of the cervical cord, and electromyography in another patient showed after 6 months evidence of segmental chronic denervation. Both abnormalities were found at the clinically expected level. The findings are consistent with a small infarction of the cervical cord in the perfusion territory of a central (sulco-commissural) artery, a duplicated anterior spinal artery or an anterior spinal branch of the vertebral artery.

  3. Sensory abnormalities and dysaesthesias in the anterior spinal artery syndrome.

    PubMed

    1992-02-01

    We present three patients with a nontraumatic cervical anterior spinal artery syndrome, two of whom developed painful burning dysaesthesias below the level of spinal cord lesion, refractory to opiate, anticonvulsant and tricyclic antidepressant therapy. Quantitative sensory testing and neurophysiological assessment showed absence of pain and temperature sensation below the level of the lesion, with preservation of light touch, vibratory and position sensibilities and cortical somatosensory evoked potentials in all three patients. Dysaesthesias in both affected patients were exacerbated by somatosensory input attributed to intact posterior column function. Posterior column electrical stimulation worsened the dysaesthesias in one affected patient, and was ineffective in the other. Both patients affected with dysaesthesias showed significant improvement in motor function and developed clinical spasticity, while the third patient developed neither dysaesthesias nor spasticity, but remained flaccid without motor improvement, suggesting a more complete lesion of anterolateral spinal pathways. These cases illustrate that lesions of the anterolateral spinal cord may lead to the development of dysaesthesias, perhaps related in part to selective neospinothalamic deafferentation and preservation of the posterior columns.

  4. Mechanisms and prevention of anterior spinal artery syndrome following abdominal aortic surgery.

    Paraplegia or paraparesis occurring as a complication of thoracic or thoracoabdominal aortic aneurysm repair is a well known phenomenon, but the vast majority of elective abdominal aortic aneurysm repairs are performed without serious neurological complications. Nevertheless, there have been many reported cases of spinal cord ischaemia following the elective repair of abdominal aortic aneurysms (AAA); giving rise to paraplegia, sphincter incontinence and, often, dissociated sensory loss. According to the classification made by Gloviczki et al. (1991), this presentation is classified as type II spinal cord ischaemia, more commonly referred to as anterior spinal artery syndrome (ASAS). It is the most common neurological complication occurring following abdominal aortic surgery with an incidence of 0.1-0.2%. Several aetiological factors, including intra-operative hypotension, embolisation and prolonged aortic crossclamping, have been suggested to cause anterior spinal artery syndrome, but the principal cause has almost always been identified as an alteration in the blood supply to the spinal cord. A review of the literature on the anatomy of the vascular supply of the spinal cord highlights the significance of the anterior spinal artery as well as placing additional emphasis on the great radicular artery of Adamkiewicz (arteria radicularis magna) and the pelvic collateral circulation. Although there have been reported cases of spontaneous recovery, complete recovery is uncommon and awareness and prevention remains the mainstay of treatment. However, being so tragically unpredictable and random, spinal cord ischaemia after abdominal aortic operations appears to be an unpreventable event. PMID:25757179

    We report a case of left upper cervical posterior spinal artery (PSA) syndrome caused by atherosclerosis of the left vertebral artery. A 70-year-old female experienced sudden dizziness and paralysis of the left upper and lower limbs. Diffusion-weighted magnetic resonance imaging (DWI) of the brain showed high signal intensity at the vermis and lower left hemisphere of the cerebellum, and magnetic resonance angiography showed that the entire left vertebral artery was thin. The patient was treated with an intravenous infusion of tissue plasminogen activator 2 hours after symptom onset and made a full recovery. Repeat DWI, fluid-attenuated inversion recovery images, and T2-weighted images showed high signal intensity in the left upper cervical PSA area from the lower medulla oblongata to the C2 level in addition to the cerebellum. Previously reported cases of cervical posterior artery syndrome are reviewed. PMID:27012218

    Background Context. Percutaneous balloon kyphoplasty is an established minimally invasive technique to treat painful vertebral compression fractures, especially in the context of osteoporosis with a minor complication rate. Purpose. To describe the heparin anticoagulation treatment of paraplegia following balloon kyphoplasty. Study Design. We report the first case of an anterior spinal artery syndrome with a postoperative reversible paraplegia following a minimally invasive spine surgery (balloon kyphoplasty) without cement leakage. Methods. A 75-year-old female patient underwent balloon kyphoplasty for a fresh fracture of the first vertebra. Results. Postoperatively, the patient developed an acute anterior spinal artery syndrome with motor paraplegia of the lower extremities as well as loss of pain and temperature sensation with retained proprioception and vibratory sensation. Complete recovery occurred six hours after bolus therapy with 15.000 IU low-molecular heparin. Conclusion. Spine surgeons should consider vascular complications in patients with incomplete spinal cord syndromes after balloon kyphoplasty, not only after more invasive spine surgery. High-dose low-molecular heparin might help to reperfuse the Adamkiewicz artery. PMID:25210639

    1993-05-01

    We studied a previously healthy 25-year-old woman with the anterior spinal artery syndrome, a rare thoracocervical myelopathy with multiple potential etiologies. Quantitative and clinical sensory examination showed dissociated loss of pin-prick and temperature discrimination below the level of the lesion, with normal light touch, vibratory, and position sense. Magnetic resonance imaging was consistent with cervical spinal cord infarction. Median SEPs showed normal Erb's potential with absent spinal N13- and normal scalp N20- latency. Tibial SEPs showed normal lumbosacral responses and normal scalp P30- latency. Both median and tibial nerve stimulation produced cortical responses of unusually large amplitude (median 38 microV, tibial 17 microV). We hypothesize that large SEP amplitudes in this patient resulted from loss of anterolateral inhibitory influences on the dorsal column-medial lemniscal system. PMID:8515757

    Anterior spinal artery syndrome (ASAS) often leads to complete motor paralysis with poor clinical outcome. There is a lack of controlled clinical trials on acute treatment strategies in ASAS. However, systemic thrombolysis with recombinant tissue-plasminogen activator (rt-PA) might be a useful therapeutic option in ASAS. We report the management of a patient with ASAS below thoracic level 10, who was treated with intravenous thrombolysis. An 81 year old patient presented with flaccid paraplegia. After exclusion of aortal dissection, spinal tumour or haemorrhage, the patient was treated with intravenous rt-PA 3 h 40 min after symptom onset. The follow up magnetic resonance imaging (MRI) showed spinal infarction below thoracic segment 10. In the clinical course, the patient partially recovered lower limb muscle strength and was able to walk with assistance. To the best of our knowledge, this is the first case in the literature of ASAS with MRI-proven spinal ischemia and the application of rt-PA. Systemic thrombolysis seems to be justifiable in patients with ASAS after the rule-out of aortal dissection and spinal bleeding. PMID:26386968

    2015-01-01

    Summary Background Spinal arteriovenous malformations (AVMs) can lead to development of congestive myelopathy (Foix-Alajouanine syndrome). Spinal AVMs are rare and so is this syndrome. Diagnosis is often missed due to its rarity and confusing definitions of the Foix-Alajouanine syndrome. Case Report We report a case of a 47-year-old male patient suffering from this rare syndrome with an AVM arising from the artery of Adamkiewicz, which is another rarity. Our patient was treated by embolization of the lesion with 20% glue, after which he showed mild improvement of symptoms. We also present a brief review of literature on spinal AVMs and elucidate the evolution of the term Foix-Alajouanine syndrome. Conclusions Use of the term “Foix-Alajouanine syndrome” should be restricted to patients with progressive subacute to chronic neurological symptoms due to congestive myelopathy caused by intradural spinal AVMs. CT angiography should supplement DSA as preliminary Imaging modality. Patients may be treated with surgery or endovascular procedures. PMID:26171088

    Two patients with unilateral popliteal artery entrapment syndrome (PAES) are reported. The importance of diligence in angiographic diagnosis and recognition of the so-called "functional" PAES group as a separate entity are stressed. It is inferred from our material that a surgical approach for PAES is to be advocated since surgical release of the entrapment can lead to complete resolution of symptoms regardless of aetiology.

    Long-term positive pressure mechanical ventilation has been the standard of care for patients with respiratory insufficiency caused by high cervical spine injury. Stimulation of the phrenic nerves, and thus the diaphragm, with an implanted phrenic nerve pacemaker has provided adequate ventilation and an alternative to the standard. Diaphragmatic pacing, also known as electrophrenic respiration, requires an intact phrenic nerve to act as a conduit for the applied stimulus. Propagation of the stimulus is impossible if the injury sustained has led to axonal loss in the phrenic nerve. This may be expected if the damage to the spinal cord is at the C3-C5 level. If the cell bodies of the motor neurons in this region have been damaged, or direct injury to the phrenic nerve has occurred, then diaphragmatic pacing is not feasible by the traditional method. Microsurgical repair of peripheral nerves and nerve grafting have provided the impetus for research into anastomosis of a viable intercostal nerve to a nonfunctional phrenic nerve, with subsequent reinnervation of the diaphragm. Once successful axonal regeneration and diaphragmatic reinnervation have occurred, the distal phrenic nerve may then be paced. This case documents the first successful institution of electrophrenic respiration after intercostal to phrenic nerve anastomosis. PMID:7808625

    Summary Background Spinal artery ischemia is a rare but serious complication of embolization for treatment of hemoptysis. When the spinal artery is visualized at angiography, embolization should not be performed. However, it has been reported that spinal artery feeders are not visible on angiography in patients with developing spinal infarction. Case Report A 70-year-old man with a history of pulmonary aspergillosis had hemoptysis and underwent contrast-enhanced CT, revealing a pulmonary artery pseudoaneurysm (PAP) in the left upper lobe. Systemic angiography from the fifth left intercostal artery showed the PAP at the distal site, but the access route to the PAP was very tortuous and long. Although the spinal branch could not be observed with that angiography, CT during angiography was performed, and it visualized the posterior spinal artery obviously. Thus, the artery distal and proximal to the PAP was then successfully coil-embolized from the pulmonary artery. Conclusions CT during angiography may be useful to confirm the presence of the spinal artery for treatment of hemoptysis by embolization.

    Segmental spinal dysgenesis (SSD) is a rare congenital spinal abnormality characterized by segmental dysgenesis or agenesis of the thoracolumbar or lumbar spine, congenital kyphosis, and abnormal configuration of the underlying spinal cord. A unique feature of SSD is that the vertebrae are present above and below the defect, and there is often a lower cord segment in the caudal spinal canal. We report a fetal MRI case of SSD with postmortem and neuropathological correlations. Our report confirms already published findings including the presence of a neurenteric cyst but is the first to document anterior spinal artery segmental agenesis in SSD. PMID:26969176

    2011-01-01

    Background: Myelopathy from ectatic vertebral artery compression of the spinal cord at the cervicomedullary junction is a rare condition. Case Description: A 63-year-old female was originally diagnosed with occult hydrocephalus syndrome after presenting with symptoms of ataxia and urinary incontinence. Ventriculoperitoneal shunting induced an acute worsening of the patient′s symptoms as she immediately developed a sensory myelopathy. An MR scan demonstrated multiple congenital abnormalities including cervicomedullary stenosis with anomalous vertebral artery compression of the dorsal spinal cord at the cervicomedullary junction. The patient was taken to surgery for a suboccipital craniectomy, C1-2 laminectomy, vertebral artery decompression, duraplasty, and shunt ligation. Intraoperative findings confirmed preoperative radiography with ectactic vertebral arteries deforming the dorsal aspect of the spinal cord. There were no procedural complications and at a 6-month follow-up appointment, the patient had experienced a marked improvement in her preoperative signs and symptoms. Conclusion: Myelopathy from ectatic vertebral artery compression at the cervicomedullary junction is a rare disorder amenable to operative neurovascular decompression. PMID:21886876

    The aim of this study was to investigate the arterial blood supply of the thoracolumbar spinal cord in rabbit. The study was carried out on twenty adult New Zealand white rabbits. Ten rabbits were used in the corrosion technique and ten rabbits in the dissection technique. After the killing, the vascular network was perfused with saline. Batson's corrosion casting kit no. 17 © was used as a casting medium. After polymerisation of the medium, in ten rabbits the maceration was carried out in KOH solution, and in ten other rabbits, formaldehyde was injected by the dissection technique into the vertebral canal. We found high variability of segmental arteries supplying blood to the spinal cord. There are 12 intercostal arteries and 1 costo-abdominal artery. Dorsal branches arising from the dorsal surface of the aorta thoracica were found as follows: in 70% of the cases, 9 pairs were present; in 20% of the cases 8 pairs; and in 10% of the cases 10 pairs. The paired arteriae lumbales were present in 6 pairs in 90% of the cases and in 5 pairs in 10% of the cases. On the dorsal surface of spinal cord, we found two irregular longitudinal arteries in 70% of the cases, no longitudinal arteries in 20% of the cases and three irregular longitudinal arteries in 10% of the cases receiving dorsal branches of rami spinales. Among the dorsal branches observed in the thoracic region, 60.5% were left-sided, 39.5% right-sided and in the lumbar region, 52.5% were left-sided and 47.5% right-sided. PMID:23952724

    Anterior spinal artery syndrome (ASAS) is a rare complication after surgery of the thoracic or abdominal aorta. The sulco commissuralis syndrome represents a partial or incomplete ASAS. We report two cases of ischemic spinal cord syndromes after transthoracic esophagectomy. This represents a prevalence of this syndrome of 0.2% in more than 1000 consecutive esophagectomies performed at our institution. Patient 1 developed an ASAS on the first day after esophagectomy. Patient 2 showed the pathognomonic clinical signs associated with sulco commissuralis syndrome after an asymptomatic window. In both patients, the extent of the neurologic symptoms initially improved but then remained unchanged for the rest of the follow-up of 9 and 12 months. Although the prognosis of neurologic syndromes resulting from spinal cord infarction is poor, preoperative tests to identify patients at risk appear not to be justified because of the very low incidence of these syndromes after esophagectomy and the poor sensitivity and specificity of currently available diagnostic modalities. However, the possibility of ischemic spinal cord syndrome should be kept in mind when patients present with neurologic symptoms after esophagectomy. PMID:11284985

    Posterior spinal artery (PSA) aneurysms are a rare cause of subarachnoid hemorrhage (SAH). The commonly abused street drug 3,4-methylenedioxymethamphetamine (MDMA) or ‘Ecstasy’ has been linked to both systemic and neurological complications. A teenager presented with neck stiffness, headaches and nausea after ingesting ‘Ecstasy’. A brain CT was negative for SAH but a CT angiogram suggested cerebral vasculitis. A lumbar puncture showed SAH but a cerebral angiogram was negative. After a spinal MR angiogram identified abnormalities on the dorsal surface of the cervical spinal cord, a spinal angiogram demonstrated a left PSA 2 mm fusiform aneurysm. The patient underwent surgery and the aneurysmal portion of the PSA was excised without postoperative neurological sequelae. ‘Ecstasy’ can lead to neurovascular inflammation, intracranial hemorrhage, SAH and potentially even de novo aneurysm formation and subsequent rupture. PSA aneurysms may be treated by endovascular proximal vessel occlusion or open surgical excision. PMID:24994748

    Turner syndrome (TS) is a relatively common chromosomal disorder and is associated with a range of comorbidities involving the cardiovascular system. Vascular abnormalities, in particular, are a common finding in cases of TS. However, dissection involving the vertebral arteries is rare. Here, we report the case of a 9-year-old girl with TS who had been treated with growth hormone replacement therapy for the past 3 years. She presented with weakness of both lower legs, and was ultimately diagnosed with spinal hemorrhage due to vascular malformation. We treated her with intravenous high dose dexamethasone (0.6 mg/kg) and she could walk without assistance after 6 days of treatment. In conclusion, when a patient with TS shows sudden weakness of the lower limbs, we should consider the possibility of spinal vessel rupture and try to take spine magnetic resonance imaging as soon as possible. We suggest a direction how to make a proper diagnosis and management of sudden vertebral artery hemorrhage in patients with TS. PMID:26817012

    Adamkiewicz artery became important in clinical practice since it was noticed that its damage during aorta aneurysm repair surgery can sometimes lead to distal spinal cord ischemia. The complexity of anatomical variations can be related to the development of spinal cord arteries. The aim was to describe topography of Adamkiewicz artery and its relations to the anterior spinal artery in fetuses. The study was carried on 4 Batson's resin corrosion casts and 24 formalin-fixed fetuses injected with dyed gelatin or latex aged 15-24 weeks gestational age. In fixed specimens vertebral canals were dissected, the anterior spinal artery was traced and Adamkiewicz artery localized. Arteries were photographed and digitally measured. Data were afterwards statistically analyzed. Anterior spinal artery was duplicated in 3/28 cases. There were from 1 to 3 Adamkiewicz arteries per specimen, mean 1.71. No relation was found between the number of Adamkiewicz artery and age. In 37/48 cases Adamkiewicz artery emptied into the anterior spinal artery on the left side. Mean degree of narrowing in anterior spinal artery (diameter of the anterior spinal artery above junction with Adamkiewicz artery divided by its diameter under that junction) was 76.74%. The diameter of Adamkiewicz artery was also correlated linearly with the degree of narrowing of anterior spinal artery (r=0.68; p<0.05). The arteries of the anterior aspect of thoracolumbar spinal cord in the 2nd trimester of pregnancy represent the adult pattern. A potentially great impact of Adamkiewicz artery on the distal spinal cord circulation may be postulated on the basis of these morphological data. PMID:26749686

    Anatomical vascular variations are rare causes of carpal tunnel syndrome. An aberrant medial artery is the most common vascular variation, while an aberrant radial artery causing carpal tunnel syndrome is even more rare, with an incidence ranging less than 3%. This article reports a patient with compression of the median nerve at the carpal tunnel by an aberrant superficial branch of the radial artery. An 80- year- old man presented with a 5-year history of right hand carpal tunnel syndrome; Tinel sign, Phalen test and neurophysiological studies were positive. Open carpal tunnel release showed an aberrant superficial branch of the radial artery with its accompanying veins running from radially to medially, almost parallel to the median nerve, ending at the superficial palmar arterial arch. The median nerve was decompressed without ligating the aberrant artery. At the last follow-up, 2 years after diagnosis and treatment the patient is asymptomatic. PMID:27517078

    A 4-year-old dog was presented for acute, progressive tetraparesis and cervical hyperesthesia. Symmetrical tubular structures coursing along the lateroventral aspects of the spinal cord at the fourth and fifth cervical vertebrae were identified in magnetic resonance images. At necropsy, vertebral arteries and their spinal branches were severely ectatic bilaterally, and the cervical spinal cord was compressed. Histologically, the ectatic branches of the vertebral and ventral spinal arteries were surrounded by fibrosis with scant mononuclear cell infiltrates and hemorrhage. Spinal branches of the vertebral arteries had focally severe reduction in the tunica media. A thrombus was in an arterial branch. Smaller vessels in adjacent tissue had fibrinoid degeneration. Axonal degeneration was detected in the affected spinal cord and nerve roots. The segmental degenerative radiculomyelopathy in this dog was attributed to anomalous ectasia of the vertebral and ventral spinal arteries. PMID:21856870

    Goldenhar Syndrome is characterized by craniofacial, ocular and vertebral defects secondary to abnormal development of the 1st and 2nd branchial arches and vertebrae. Other findings include cardiac and vascular abnormalities. Though these associations are known, the specific anomalies are not well defined. We present a 7-month-old infant with intermittent respiratory distress that did not improve with respiratory interventions. Echocardiogram suggested a double aortic arch. Cardiac CT angiogram confirmed a right arch and aberrant, stenotic left subclavian artery, dilation of the main pulmonary artery, and agenesis of the left thyroid lobe. Repeat echocardiograms were concerning for severely dilated coronary arteries. Given dilation, a rheumatologic workup ensued, only identifying few weakly positive autoantibodies. Further imaging demonstrated narrowing of the aorta below the renal arteries and extending into the common iliac arteries and proximal femoral arteries. Given a physical exam devoid of rheumatologic findings, only weakly positive autoantibodies, normal inflammatory markers, and presence of the coronary artery dilation, the peripheral artery narrowings were not thought to be vasculitic. This case illustrates the need to identify definitive anomalies related to Goldenhar Syndrome. Although this infant's presentation is rare, recognition of specific vascular findings will help differentiate Goldenhar Syndrome from other disease processes. PMID:26688769

  11. Tail arteries from chronically spinalized rats have potentiated responses to nerve stimulation in vitro

    Patients with severe spinal cord lesions that damage descending autonomic pathways generally have low resting arterial pressure but bladder or colon distension or unheeded injuries may elicit a life-threatening hypertensive episode. Such episodes (known as autonomic dysreflexia) are thought to result from the loss of descending baroreflex inhibition and/or plasticity within the spinal cord. However, it is not clear whether changes in the periphery contribute to the exaggerated reflex vasoconstriction. The effects of spinal transection at T7–8 on nerve- and agonist-evoked contractions of the rat tail artery were investigated in vitro. Isometric contractions of arterial segments were recorded and responses of arteries from spinalized animals (‘spinalized arteries’) and age-matched and sham-operated controls were compared. Two and eight weeks after transection, nerve stimulation at 0.1–10 Hz produced contractions of greater force and duration in spinalized arteries. At both stages, the α-adrenoceptor antagonists prazosin (10 nm) and idazoxan (0.1 μm) produced less blockade of nerve-evoked contraction in spinalized arteries. Two weeks after transection, spinalized arteries were supersensitive to the α1-adrenoceptor agonist phenylephrine, and the α2-adrenoceptor agonist, clonidine, but 8 weeks after transection, spinalized arteries were supersensitive only to clonidine. Contractions of spinalized arteries elicited by 60 mm K+ were larger and decayed more slowly at both stages. These findings demonstrate that spinal transection markedly increases nerve-evoked contractions and this can, in part, be accounted for by increased reactivity of the vascular smooth muscle to vasoconstrictor agents. This hyper-reactivity may contribute to the genesis of autonomic dysreflexia in patients. PMID:14766944

    Objectives: To report unique cases of Ogilvie's syndrome (acute intestinal pseudo-obstruction) following posterior spinal instrumentation in thoraco lumbar trauma. Materials and Methods: A single centre retrospective study. We reviewed the surgical data of 420 patients who underwent thoracolumbar spinal surgery over a period of four years. Two patients who developed post operative Ogilvie's syndromes were identified. Results: The clinical presentation and blood investigations ruled out any infectious pathology. Computed tomography scans ruled out the mechanical obstruction. All patients improved with conservative management. Conclusion: Ogilvie's syndrome should be considered as a differential diagnosis in patients with postoperative significant abdominal distension who had undergone posterior instrumentation for spinal trauma. Early recognition and appropriate conservative treatment would be necessary to prevent complications such as bowel ischemia and perforation. PMID:26692695

    Introduction Severe nephrotic syndrome is associated with increased morbidity and mortality. Renal artery embolization (RAE) has been used in a number of renal diseases such as renal tumors, arteriovenous fistulas etc. However, data regarding benefits of RAE in patients with symptomatic severe proteinuria is limited. We decided to evaluate role of RAE in the setting of severe symptomatic nephrotic syndrome. Methods Eight patients who had undergone transcatheter renal artery embolization with polyvinyl alcohol (PVA) were included. Clinico-demographic characteristics as well as baseline laboratory data including level of proteinuria, serum albumin, C-reactive protein and LDL cholesterol levels were recorded for each patient. After RAE, outpatient clinic control laboratory values were also assessed. Findings All patients except one underwent bilateral RAE (four simultaneous or three sequential). Two patients experienced postembolization syndrome characterized by flank pain, fever, and leukocytosis, which was self-limited and responded to analgesics in all patients. There was no technical complications associated with RAE procedure. All patients became anuric except one. Serum albumin levels increased and serum LDL-cholesterol levels decreased considerably in treated patients. Discussion Renal artery embolization with the purpose of amelioration in nephrotic syndrome complications was effective and free of major technical complications in our patients. PMID:26833695

    Rupture of isolated posterior spinal artery (PSA) aneurysms is a rare cause of subarachnoid hemorrhage (SAH) that presents unique diagnostic challenges owing to a nuanced clinical presentation. Here, we report on the diagnosis and management of the first known case of an isolated PSA aneurysm in the context of leukocytoclastic vasculitis. A 53-year-old male presented to an outside institution with acute bilateral lower extremity paralysis 9 days after admission for recurrent cellulitis. Early magnetic resonance imaging was read as negative and repeat imaging 15 days after presentation revealed SAH and a compressive spinal subdural hematoma. Angiography identified a PSA aneurysm at T9, as well as other areas suspicious for inflammatory or post-hemorrhagic reactive changes. The patient underwent a multilevel laminectomy for clot evacuation and aneurysm resection to prevent future hemorrhage and to establish a diagnosis. The postoperative course was complicated by medical issues and led to the diagnosis of leukocytoclastic vasculitis that may have predisposed the patient to aneurysm development. Literature review reveals greater mortality for cervical lesions than thoracolumbar lesions and that the presence of meningitic symptoms portents better functional outcome than symptoms of cord compression. The outcome obtained in this case is consistent with outcomes reported in the literature. PMID:27114966

    Guinea pigs are frequently used as experimental models in studies of ischemic spinal cord injury. The aim of this study was to describe the arterial blood supply to the thoracolumbar spinal cord in 20 adult English self guinea pigs using the corrosion and dissection techniques. The dorsal intercostal arteries arising from the dorsal surface of the thoracic aorta were found as follows: in eight pairs in 70% of cases, in seven pairs in 20% of cases and in nine pairs in 10% of cases. Paired lumbar arteries were present as seven pairs in all the cases. The occurrence of the ventral and dorsal branches of the spinal rami observed in the thoracic and lumbar region was higher on the left than on the right. The artery of Adamkiewicz was present in 60% of cases as a single vessel and in 40% of cases as a double vessel. On the dorsal surface of the spinal cord, we found two dorsal spinal arteries in 60% of cases and three in 40% of cases. The presence of the artery of Adamkiewicz and nearly regular segmental blood supplying the thoracolumbar part of the spinal cord in all our studied animals is the reason for using guinea pigs as a simple model of ischemic damage to the thoracolumbar part of the spinal cord.

    Since little has been reported about complications of spinal anesthesia in adult tethered cord syndrome (TCS), we sought to delineate the characteristics of the condition.A total of 4 cases of adult TCS after spinal anesthesia were reviewed. The medical charts of the patients were obtained. Anesthesia, which was combined spinal and epidural anesthesia or spinal anesthesia was performed, and follow-up were carried out in all patients.The most common neurological symptom of adult TCS before surgery was occasional severe pain in back, perineal region, or legs. Frequent micturition, diminished knee and ankle reflexes, and difficulty in bending were exhibited in partial patients. Paraesthesia of perineal region or/and lower extremities existed 2 to 3 days after spinal anesthesia in all the cases. Weakness of lower extremities existed in 1 case. Lumbar magnetic resonance imaging showed the low location of conus medullaris. At follow-up, 3 cases recovered completely within 3 weeks, and 1 case underwent permanent disability.These cases suggest anesthesiologists and surgeons alert to the association of adult TCS and spinal anesthesia. Spinal anesthesia should be prohibited in patients with adult TCS to prevent neurological damages. PMID:27442670

    Guillain-Barré syndrome is a relatively common, acute, and rapidly progressive, inflammatory demyelinating polyneuropathy. The diagnosis is usually established on the basis of symptoms and signs, aided by cerebrospinal fluid findings and electrophysiologic criteria. Previously, radiologic examinations have been used only to rule out other spinal abnormalities. We report a case of systemic lupus erythematosus associated with Guillain-Barré syndrome with marked enhancement of nerve roots of the conus medullaris and cauda equina on MR imaging. These MR observations may help confirm the diagnosis of Guillain-Barré syndrome. PMID:22470650

    2015-01-01

    Superior mesenteric artery (SMA) syndrome (known as Wilkie's syndrome) is a rare cause of upper gastrointestinal obstruction. It is an acquired disorder in which acute angulation of the SMA causes compression of the third part of the duodenum between the SMA and the aorta. This is commonly due to loss of fatty tissue as a result of a variety of debilitating conditions. We report a 17-year-old female who presented with intermittent abdominal pain and intractable vomiting following significant weight loss after hospitalization for pneumonia. Symptoms persisted for 2 years and the patient underwent extensive invasive and non-invasive tests, but to no avail. Thereafter she developed acute high intestinal obstruction, which unraveled her diagnosis. This case emphasizes the challenges in the diagnosis of SMA syndrome and the need for increased awareness of this entity. This will improve early recognition in order to reduce irrelevant tests and unnecessary treatments. PMID:26120301

    Spinal subarachnoid hemorrhage (SAH) due to solitary spinal aneurysm is extremely rare. A 45-year-old female patient visited the emergency department with severe headache and back pain. Imaging studies showed cerebral SAH in parietal lobe and spinal SAH in thoracolumbar level. Spinal angiography revealed a small pearl and string-like aneurysm of the Adamkiewicz artery at the T12 level. One month after onset, her back pain aggravated, and follow-up imaging study showed arachnoiditis. Two months after onset, her symptoms improved, and follow-up imaging study showed resolution of SAH. The present case of spinal SAH due to rupture of dissecting aneurysm of the Adamkiewicz artery underwent subsequent spontaneous resolution, indicating that the wait-and-see strategy may provide adequate treatment option.

    A 50-year-old woman presented with a subarachnoid hemorrhage caused by a ruptured vertebral artery dissecting aneurysm(VADA)involving the anterior spinal artery(ASA). The ASA branched at the proximal component of the dissecting aneurysm. The rupture point was presumed to be the distal region of the dissecting aneurysm. We performed coil embolization of the distal part only in order to prevent rebleeding and preserve the ASA. The patient showed no neurological deficits. Six months after the procedure, an angiogram demonstrated occlusion of a distal portion of the right vertebral artery. However, the ASA was still patent. No rebleeding occurred, and the patient has remained neurologically symptom-free for 3 years from the treatment. ASA-involved VADAs are extremely rare. Treatment strategy is difficult because there are no options for bypass surgery and occlusion of the ASA may lead to quadriplegia unless there is collateral flow to the ASA. Although the outcome of the patient was good with partial coil embolization in this case, the treatment strategy should be carefully considered for ASA-involved VADAs. PMID:27384118

    Presurgical devascularization of hypervascular spinal metastases has been shown to be effective in preventing major blood loss during open surgery. Most often, embolization can be performed using polyvinyl alcohol (PVA) microparticles. However, in some cases, the close relationship between the feeders of the metastases and the feeders of the anterior spinal artery (ASA) poses a risk of spinal cord ischemia when PVA microparticle embolization is performed. The authors present their early experience in the treatment of spinal metastases close to the ASA; in 2 cases they injected Onyx-18, by direct puncture, into hypervascular posterior arch spinal metastases situated close to the ASA. Two women, one 36 and the other 55 years of age, who presented with spinal lesions (at the posterior arch of C-4 and T-6, respectively) from thyroid and a kidney tumors, were sent to the authors' department to undergo presurgical embolization. After having performed a complete spinal digital subtraction angiography study, a regular angiography catheter was positioned at the ostium of the artery that mainly supplied the lesion. Then, with the patient in the left lateral decubitus position, direct puncture with 18-gauge needles of the lesion was performed using roadmap guidance. Onyx-18 was injected through the needles under biplanar fluoroscopy. Satisfactory devascularization of the lesions was obtained; the ASA remained patent in both cases. The metastases were surgically removed in both cases within the 48 hours after the embolization and major blood loss did not occur. Presurgical devascularization of hypervascular spinal metastases close the ASA by direct puncture with Onyx-18 seems to be an effective technique and appears to be safe in terms of the preserving the ASA's patency.

    Isolated spinal artery aneurysms are exceedingly rare vascular lesions thought to be related to dissection of the arterial wall. We describe two cases presenting with spinal subarachnoid haemorrhage that underwent conservative management. In the first patient the radiculomedullary branch involved was feeding the anterior spinal artery at the level of D3 and thus, neither endovascular nor surgical approach was employed. Control angiography was performed at seven days and at three months, demonstrating complete resolution of the lesion. In our second case, neither the anterior spinal artery or the artery of Adamkiewicz could be identified during angiography, thus endovascular management was deemed contraindicated. Magnetic resonance imaging showed a stable lesion in the second patient. No rebleeding or other complications were seen. In comparison to intracranial aneurysms, spinal artery aneurysms tend to display a fusiform appearance and lack a clear neck in relation to the likely dissecting nature of the lesions. Due to the small number of cases reported, the natural history of these lesions is not well known making it difficult to establish the optimal treatment approach. Various management strategies may be supported, including surgical and endovascular treatment, but It would seem that a wait and see approach is also viable, with control angiogram and treatment decisions based on the evolution of the lesion.

    We review the anatomy of the spinal cord, providing correlation with key functional and clinically relevant neural pathways, as well as magnetic resonance imaging. Peripherally, the main descending (corticospinal tract) and ascending (gracilis or cuneatus fasciculi and spinothalamic tracts) pathways compose the white matter. Centrally, the gray matter can be divided into multiple laminae. Laminae 1-5 carry sensitive neuron information in the posterior horn, and lamina 9 carries most lower motor neuron information in the anterior horn. Damage to the unilateral corticospinal tract (upper motor neuron information) or gracillis-cuneatus fasciculi (touch and vibration) correlates with ipsilateral clinical findings, whereas damage to unilateral spinothalamic tract (pain-temperature) correlates with contralateral clinical findings. Damage to commissural fibers correlates with a suspended bilateral "girdle" sensory level. Autonomic dysfunction is expected when there is bilateral cord involvement. PMID:27616310

    Objectives This study included a series of middle-aged male and female patients who presented with chronic anterior hemicord dysfunction progressing to paraplegia. Imaging of anterior thoracic cord displacement by either a dural adhesion or a dural defect with associated cord herniation is presented. Methods This is a retrospective review of cases referred to a tertiary neuroscience centre over a 19-year period. Imaging series were classified by two experienced neuroradiologists against several criteria and correlated with clinical examination and/or findings at surgery. Results 16 cases were available for full review. Nine were considered to represent adhesions (four confirmed surgically) and four to represent true herniation (three confirmed surgically). In the three remaining cases the diagnosis was radiologically uncertain. Conclusion The authors propose “thoracic anterior spinal cord adhesion syndrome” as a novel term to describe this patient cohort and suggest appropriate clinicoradiological features for diagnosis. Several possible aetiologies are also suggested, with disc rupture and inflammation followed by disc resorption and dural pocket formation being a possible mechanism predisposing to herniation at the extreme end of a clinicopathological spectrum.

    The authors report the case of a 12-year-old boy with spinal cord arteriovenous malformation (AVM) and an associated anterior spinal artery (ASA) aneurysm treated with selective coil placement in the context of subarachnoid hemorrhage (SAH). The patient presented with headache. Head computed tomography scanning revealed no abnormal findings. The cerebrospinal fluid was sampled and analyzed and a diagnosis of SAH was established. Investigation, including magnetic resonance imaging of the cord as well as cerebral and spinal angiography, revealed a conus medullaris AVM and a saccular aneurysm located on the ASA at the T-11 level. The aneurysm was thought to be responsible for the bleeding. Superselective ASA angiography showed that the aneurysm was at the bifurcation between a large coronal artery supplying the AVM and the ASA. The relation of the aneurysm's neck to the main spinal axis and the aneurysm's morphological features indicated that the lesion was suited for endosaccular coil therapy. The aneurysm was selectively occluded, using electrodetachable bare platinum coils. Follow-up angiography immediately after surgery and at 6 months thereafter demonstrated complete occlusion of the aneurysm and a perfectly patent anterior spinal axis. On clinical follow-up examination, the patient remained neurologically intact. When the morphological features of a spinal aneurysm and its relation with the anterior spinal axis are favorable, selective endosaccular coil placement can successfully be achieved. PMID:17542515

    Preoperative splenic artery embolization for massive splenomegaly has been shown to reduce intraoperative hemorrhage during splenectomy. We describe a case of tumor lysis syndrome after proximal splenic artery embolization in a patient with advanced mantle cell lymphoma and splenic involvement. The patient presented initially with hyperkalemia two days after embolization that worsened during splenectomy. He was stabilized, but developed laboratory tumor lysis syndrome with renal failure and expired. High clinical suspicion of tumor lysis syndrome in this setting is advised. Treatment must be started early to avoid serious renal injury and death. Lastly, same day splenectomy and embolization should be considered to decrease the likelihood of developing tumor lysis syndrome. PMID:27257458

    A new method of diagnosing and defining functional popliteal artery entrapment syndrome is described. By combining ultrasonography and magnetic resonance imaging techniques with dynamic plantarflexion of the ankle against resistance, functional entrapment can be demonstrated and the location of the arterial occlusion identified.

    Objective Aneurysms-osteoarthritis syndrome (AOS), caused by SMAD3 mutations, is a recently described autosomal-dominant syndrome characterized by arterial aneurysms, tortuosity, and aortic dissections in combination with osteoarthritis. Our objective was to evaluate the AOS-related vascular consequences in the visceral and iliac arteries and raise awareness for this aggressive syndrome among vascular specialists. Methods All AOS patients were monitored regularly according to our clinical AOS protocol. The study included those with one or more visceral aneurysms or tortuosity, or both. Clinical and surgical data were obtained from record abstraction. Results The study included 17 AOS patients (47% men) aged 47 ± 13 years. A total of 73 aneurysms were encountered, of which 46 were located in the abdomen. The common iliac artery was most commonly affected (37%), followed by the superior mesenteric artery (15%), celiac trunk (11%), and splenic artery (9%). Rapid aneurysm growth ≤1 year was found in three arteries (gastric, hepatic, and vertebral artery). Furthermore, arterial tortuosity was noted in 94% of patients. Four patients underwent six elective (endo) vascular interventions for aneurysms in the iliac, hepatic, gastric, or splenic artery, without major perioperative or postoperative complications. Conclusions AOS predisposes patients to widespread visceral and iliac artery aneurysms and extreme arterial tortuosity. Early elective aneurysm repair should be considered because the risk of aneurysm rupture is estimated to be very high and elective (endo) vascular interventions were not complicated by fragility of arterial tissue. Given the aggressive behavior of AOS, it is of utmost importance that vascular specialists are aware of this new syndrome. PMID:22975338

    Osteochondroma is a common benign bone lesion, usually involving the long bones. Spinal involvement is rare. The clinical presentation of spinal osteochondroma varies according to the site of the lesion. The most common reported clinical presentation is secondary to encroachment of the lesion on the spinal canal or nerve roots. Less common presentations such as a palpable neck mass, dysphagia, sleep apnea, paralysis of left vocal cord or acute respiratory distress have been reported when the lesions compress the anatomic structures anteriorly. We describe a rare case of a young patient who presented with an emergent critical condition of acute cerebellar infarct as a result of vertebral artery compression caused by a solitary C1 spinal osteochondroma.

    Many spinal cord circulatory disorders present the substantial involvement of small vessel lesions. The central sulcus arteries supply nutrition to a large part of the spinal cord, and, if not detected early, lesions in the spinal cord will cause irreversible damage to the function of this organ. Thus, early detection of these small vessel lesions could potentially facilitate the effective diagnosis and treatment of these diseases. However, the detection of such small vessels is beyond the capability of current imaging techniques. In this study, an imaging method is proposed and the potential of phase-contrast imaging (PCI)- and attenuation-contrast imaging (ACI)-based synchrotron radiation for high-resolution tomography of intramedullary arteries in mouse spinal cord is validated. The three-dimensional vessel morphology, particularly that of the central sulcus arteries (CSA), detected with these two imaging models was quantitatively analyzed and compared. It was determined that both PCI- and ACI-based synchrotron radiation can be used to visualize the physiological arrangement of the entire intramedullary artery network in the mouse spinal cord in both two dimensions and three dimensions at a high-resolution scale. Additionally, the two-dimensional and three-dimensional vessel morphometric parameter measurements obtained with PCI are similar to the ACI data. Furthermore, PCI allows efficient and direct discrimination of the same branch level of the CSA without contrast agent injection and is expected to provide reliable biological information regarding the intramedullary artery. Compared with ACI, PCI might be a novel imaging method that offers a powerful imaging platform for evaluating pathological changes in small vessels and may also allow better clarification of their role in neurovascular disorders.

    Background: Effective management of a spinal dural arteriovenous fistula (SDAVF) can be accomplished with either microsurgery or endovascular embolization, but there is a consensus that in patients in whom a radiculomedullary artery supplying the anterior spinal artery (ASA) originates from the same feeding artery as the SDAVF, the endovascular approach is to be avoided. Case Description: The patient was a 46-year-old woman with progressive lower limb paraparesis, sensory deficit, and sphincter dysfunction. Magnetic resonance imaging (MRI) and spinal angiography showed an SDAVF fed by a branch from the left second lumbar segmental artery, and the artery of Adamkiewicz (AA), a major ASA supplier, originating from the same segmental artery just proximal to the SDAVF. Microsurgical disconnection of the SDAVF was attempted, but failed. Embolization with cyanoacrylates was done in two occasions, the first time through a microcatheter placed just distal to the origin of the AA and the second time through another feeder coming from the same segmental artery that could not be visualized in the previous angiographies. All procedures were neurologically uncomplicated. Magnetic resonance imaging (MRI) 1 month after the last embolization showed resolution of the spinal cord edema. MRI scan taken 68 months after embolization revealed a slightly atrophic spinal cord with visible central canal and no recurrence of medullary edema. The patient presented good, but incomplete neurological improvement. Conclusion: Microsurgery is the first choice for an SDAVF branching off the same radiculomedullary artery supplying the ASA, but uncomplicated embolization can be feasible after failed surgery.

    Objectives To investigate what clinical features typically present in transurethral resection (TUR) syndrome and to see which classically present first. The purpose of the study was to establish whether or not a particular method of anesthesia is preferred in detecting this syndrome in its early stages. Methods A total of 1,502 transurethral resection of the prostate (TURP) over a 15 year period were reviewed to see which, if any, went on to experience this complication. Of these cases, 48 developed TUR syndrome. The case records were reviewed retrospectively and the presenting clinical features were analysed. All TURPs were routinely performed under spinal anesthesia and followed a standardised set up. The irrigation fluid used in all operations was Glycine 1.5%. Results Forty eight patients displayed clinical features of TUR syndrome giving an incidence of 3.2%. Trainees of varying experience caused all but one case. Median resection time, resection weight and volume of intraoperative glycine irrigation fluid were 55 minutes (range 40-75 minutes), 44 grams (range 24-65 g), and 28 l (24-48 l) respectively. Only 16/48 TURPs had a recorded capsular perforation. Pre- vs. post-operative median hematocrit, hemoglobin and serum sodium were 0.42 vs. 0.33, 14.2 g/dl vs. 10.1 g/dl and 142 mmol/l vs. 121 mmol/l respectively. Patients presented with nausea 44/48, vomiting 28/48, visual disturbance 29/48, apprehension 37/48, disorientation 17/48, breathing difficulties 17/48, and bradycardia 19/21. The earliest observed sign was nausea 21/48, then bradycardia 11/48, apprehension 11/48, and visual disturbance 10/48; after which the procedure was abandoned. None of the patients developed stupor, coma or seizures. Out of the 48 patients, 9 were admitted to high dependency units and all of these were treated with IV furosemide. One patient required a blood transfusion. All patients recovered within 48 hours (range 18-48 hours) and none had any long term complications on follow up

    The subclavian-vertebral artery steal syndrome (SSS) is the hemodynamic phenomenon of blood flow reversal in the vertebral artery due to significant stenosis or occlusion of the proximal subclavian artery or the innominate artery. Occasionally, SSS is diagnosed in patients not harboring arterial stenosis. With the exception of arterial congenital malformations, the limited case reports of SSS with intact subclavian artery are attributed to dialysis arteriovenous fistulas (AVFs). Interestingly, these cases are more frequently symptomatic than those with the classical atherosclerotic SSS forms. On the other hand, the disclosure of SSS due to subclavian/innominate artery atherosclerotic stenosis, even in the absence of accompanying symptoms, should prompt a thorough cardiovascular work-up for the early detection of coexisting coronary, carotid, or peripheral artery disease. Herein, we review the incidence, clinical presentation, sonographic findings, and therapeutic interventions related to SSS with and without subclavian/innominate artery stenosis. We also review the currently available data in the literature regarding the association of SSS and dialysis AVF. In addition, we present a patient with bilateral symptomatic SSS as the result of an arteriovenous graft (AVG) that was introduced after the preexisting AVF in the contralateral arm became nonfunctional. SSS due to subclavian or innominate artery stenosis/occlusion is rarely symptomatic warranting interventional treatment. In contrast, when it is attributed to AVF, surgical correction is frequently necessary. PMID:27301069

    Purpose: To review some aspects of the problem of splenic artery steal syndrome as cause of ischemia in transplanted livers and treatment by selective splenic artery occlusion. Materials and Methods: Eleven liver transplant patients from a group of 350 patients, nine men and two women,ranging in age from 40 years to 61 years (mean 52 years), presented with biochemical evidences of liver ischemia and failure, ranging from one to 60 days following orthotopic liver transplantation. Diagnosis of splenic artery steal syndrome was suspected by elevated enzymes, Doppler ultrasound and confirmed by celiac angiogram. Patients with confirmed hepatic artery thrombosis before angiography were excluded from the study. Embolization with Gianturco coils was performed. Results: All patients were treated by splenic artery embolization with Gianturco coils. The 11 patients improved clinically within 24 hours of the procedure with significant change in the biochemical and clinical parameters. Followup ranged from one month to two years. One of the 11 patient initially improved, but developed hepatic artery thrombosis within 24 hours of the embolic treatment,requiring surgical repair. Conclusion: Splenicartery steal syndrome following liver transplantation surgery can be diagnosed by celiac angiography, and effectively treated by splenic artery embolization with coils. Embolization is one of the treatments available, it is minimally invasive, and leads to immediate clinical improvement. Hepatic artery thrombosis is a possible complication of the procedure.

    Popliteal artery entrapment syndrome (PAES) is a rare condition that should be suspected in a young patient with exertional lower extremity pain. We report the case of an 18-year-old female volleyball player with bilateral exertional lower extremity pain who had been previously diagnosed with tendinitis and periostitis. Diagnostic studies showed entrapment of the left popliteal artery and the left anterior tibial artery. To our knowledge, there has only been 1 previous report of anterior tibial artery involvement in PAES. PMID:24880061

    Background: Isolated cervical anterior spinal artery aneurysms are extremely rare. Subarachnoid hemorrhage (SAH) secondary to such lesions have been described only in six cases to the best of our knowledge. Case Description: We describe an unusual clinical picture of SAH due to rupture of anterior spinal artery aneurysm in a patient with previous normal angiogram. Due to the location of the aneurysm and clinical status of the patient, conservative management was proposed, and she was discharged to further follow-up. Monthly routine angiograms revealed resolution of the aneurysm 90 days after bleeding, which was highly suggestive of vascular dissection. Conclusion: We highlight the need to consider these aneurysms in the differential diagnosis of SAH, especially when occurring in the posterior fossa and when angiography findings are inconclusive.

    A case of complete angiographic suppression of the artery of Adamkiewicz and anterior spinal artery in a patient with a spinal epidural arteriovenous fistula (AVF) is reported. Slow flow AVFs typically present with progressive myelopathy secondary to spinal venous hypertension (SVH). The lack of a normal venous phase during angiography and its restoration after treatment is commonly observed with these lesions, yet a similar phenomenon seems exceptional at the arterial level. Right T11 intercostal artery angiograms obtained before and after treatment of a left L4 epidural AVF documented the initial suppression of the artery of Adamkiewicz and anterior spinal artery, and their normal appearance immediately after correction of the SVH by embolization. This report confirms that SVH can angiographically suppress prominent and functionally important spinal arteries, re-emphasizing the potential role played by secondary arterial changes in SVH induced myelopathy. This hemodynamic phenomenon also represents a potential pitfall during diagnostic and therapeutic endovascular procedures. PMID:25028420

    A 24-year-old Ugandan woman was referred for a neurology opinion after complaining of a year long history of right-sided retro-orbital stabbing pain. Brain imaging revealed a coincidental 3 mm left ophthalmic artery aneurysm. Marfanoid habitus was noted; after further investigations she was diagnosed with mild aortic root dilatation, subtle lens dislocation and Marfan syndrome. Her symptoms were secondary to temporomandibular joint dysfunction, an under-recognised complication of Marfan syndrome. Her ophthalmic artery aneurysm is likely to be a coincidental finding.

    There are very few published reports of rupture of an isolated posterior spinal artery (PSA) aneurysm, and consequently the optimal therapeutic strategy is debatable. An 84-year-old man presented with sudden onset of restlessness and disorientation. Neuroradiological imaging showed an intracranial subarachnoid hemorrhage (SAH) with no visible intracranial vascular lesion. Spinal magnetic resonance imaging (MRI) detected a localized subarachnoid hematoma at Th10–11. Both contrast-enhanced spinal computed tomography and enhanced MRI and magnetic resonance angiography revealed an area of enhancement within the hematoma. Superselective angiography of the left Th12 intercostal artery demonstrated a faintly enhanced spot in the venous phase. Thirteen days after the onset of symptoms, a small fusiform aneurysm situated on the radiculopial artery was resected. The patient's postoperative course was uneventful and he was eventually discharged in an ambulatory condition. To our knowledge, this 84-year-old man is the oldest reported case of surgical management of a ruptured isolated PSA aneurysm. This case illustrates both the validity and efficacy of this therapeutic approach. PMID:26522607

This case presentation reviews the diagnosis, management, and treatment of such aneurysms. Case Presentation: An 88-year-old female presented with the worst headache of her life without focal deficits. She was found to have diffuse SAH in the basal cisterns extending inferiorly down the spinal canal. Review of the neurodiagnostic images revealed an anterior spinal artery aneurysm in the setting of cervical spondylosis. Conclusions: Clinicians should be suspicious of cervical spondylosis as a rare etiology for an SAH when cerebral angiograms prove negative for intracranial aneurysms. PMID:26862449

    Bow hunter's syndrome is a condition in which vertebrobasilar insufficiency is resultant from head rotation, clinically manifested by presyncopal sensation, syncope, dizziness, and nausea. It is usually diagnosed clinically, with supporting vascular imaging demonstrating an occluded or at the very least compromised unilateral vertebral artery, while the dominant vertebral artery remains patent in the neutral position. Dynamic imaging is utilized to confirm the rotational compression of the dominant vertebral artery. We present the rare case of a patient with typical Bow hunter's symptoms, bilaterally patent vertebral arteries on neutral imaging, and bilateral compromise with head rotation. Our patient underwent posterior decompression of the culprit atlanto-axial transverse foramen and subaxial cervical fusion, with resolution of his symptoms. Our patient exemplifies the possibility of bilateral dynamic vertebral artery occlusion. We show that Bow hunter's syndrome cannot be ruled out in the setting of bilaterally patent vertebral arteries on neutral imaging and that severe cervical spondylosis should impart further clinical suspicion of this unusual phenomenon.

    Introduction This is the first case report of Mirizzi syndrome associated with hepatic artery pseudoaneurysm. Case presentation A 54-year-old man presented with painful obstructive jaundice and weight loss. Computed tomography showed a hilar mass in the liver. Following an episode of haemobilia, angiography demonstrated a pseudoaneurysm of a branch of the right hepatic artery that was embolised. At surgery, a gallstone causing Mirizzi type II syndrome was found to be responsible for the biliary obstruction and a necrotic inflammatory mass and haematoma were found to be extending into the liver. The mass was debrided and drained, the obstructing stones removed and the bile duct drained with a t-tube. The patient made a full recovery. Conclusion This case highlights another situation where there may be difficulty in differentiating Mirizzi syndrome from biliary tract cancer. PMID:19014690

    Pulmonary arterial hypertension (PAH) is a progressive disorder in which endothelial dysfunction and vascular remodeling obstruct small pulmonary arteries, resulting in increased pulmonary vascular resistance and pulmonary pressures. This leads to reduced cardiac output, right heart failure, and ultimately death. In this review, we attempt to answer some important questions commonly asked by patients diagnosed with PAH pertaining to the disease, and aim to provide an explanation in terms of classification, diagnosis, pathophysiology, genetic etiologies, demographics, and prognostic factors. Furthermore, important molecular pathways that are central to the pathogenesis of PAH are reviewed, including nitric oxide, prostacyclin, endothelin-1, reactive oxygen species, and endothelial and smooth muscle proliferation.

    A combined clinical and magnetic resonance imaging follow-up study was undertaken to determine the risk of early progression to multiple sclerosis in patients who present with clinically isolated lesions of the brainstem or spinal cord. Progression to multiple sclerosis was seen in 13 patients (57%) who had a brainstem syndrome and in 14 patients (42%) who had a spinal cord syndrome after mean intervals of 15 and 16 months, respectively. The risk of progression was increased by the presence of oligoclonal bands in the cerebrospinal fluid of patients with either syndrome and by the presence of disseminated brain lesions, as detected by magnetic resonance imaging, in those with a spinal cord syndrome. Follow-up revealed evidence of multiphasic disease in 24 (69%) of 35 patients who had disseminated lesions on magnetic resonance imaging scans at presentation, suggesting that multiple sclerosis is the usual cause of such lesions.

    We experienced a case of intermittent Wolff-Parkinson-White (WPW) syndrome following spinal anesthesia. This patient had neither any past history of cardiac symptoms nor any abnormal finding in the preoperative electrocardiogram. Soon after spinal anesthesia, the level of anesthesia spread to C6. Both abbreviated PR intervals and delta waves characteristic of WPW syndrome appeared on the electrocardiogram monitor. These abnormal wave-forms continued throughout the operation, but disappeared after three days. This case was diagnosed as intermittent WPW syndrome based upon these observations. High spinal anesthesia effectively blocks the cardiac sympathetic nerve and suppresses the normal atrioventricular conduction. Further, conduction by the accessory pathway is facilitated by the relative excitement of parasympathetic nerve. In the present case, the conduction by the accessory pathway, which had originally been very poor, was transiently promoted by the above-mentioned mechanism, and abnormal wave-forms characteristic of WPW syndrome appeared temporarily in the electrocardiogram.

    A 22-year-old man presented with a sudden backache and paraplegia (ASIA = B). Magnetic resonance imaging showed an anterior pan-spinal epidural haematoma. Digital subtraction angiography was performed and ruled out an underlying vascular malformation but showed an active contrast media leakage into the T-4 ventral epidural space with a pattern of pseudo-aneurysm. A rupture of a T-4 retrocorporeal artery was considered as the aetiology, possibly caused by a haemorrhagic sub-adventitial dissection. Treatment consisted in the embolisation of both the pseudo-aneurysm and the parent artery with liquid acrylic glue, followed by neurosurgical decompression in emergency. The patient had totally recovered (ASIA = E) by the 10-month clinical follow-up. PMID:27106842

    Background Arterial Stiffness, an intermediate pre-clinical marker of atherosclerosis, has been associated with an increased risk of stroke and cardiovascular disease (CVD). The metabolic syndrome and its components are established CVD risk factors and may also increase arterial stiffness, but data on this potential relationship is limited. The goal of this study was to determine the association between the metabolic syndrome (MetSyn) and carotid artery stiffness (STIFF) in an elderly multi-ethnic cohort. Methods STIFF was assessed by carotid ultrasound as part of the Northern Manhattan Study (NOMAS), a prospective population-based cohort of stroke-free individuals. STIFF was calculated as [ln(systolicBP/diastolicBP)/Strain], where Strain was [(Systolic Diameter Diastolic Diameter)/Diastolic Diameter]. MetSyn was defined by the National Cholesterol Education Program: Adult Treatment Panel III (NCEP ATP III) criteria. LogSTIFF was analyzed as the dependent variable in linear regression models, adjusting for demographics, education, current smoking, presence of carotid plaque and intima-media thickness. Results STIFF was analyzed in 1133 NOMAS subjects (mean age 65±9 years; 61% women; 58% Hispanic, 22% Black, 20% White). The prevalence of MetSyn was 49%. The mean LogSTIFF was 2.01±0.61 among those with and 1.90±0.59 among those without MetSyn (p=0.003). MetSyn was significantly associated with increased logSTIFF in the final adjusted model (parameter estimate β=0.100, p=0.01). Among individual MetSyn components, waist circumference and elevated blood pressure were most significantly associated with a mean increase in logSTIFF (p<0.01). Conclusion MetSyn is significantly associated with increased carotid artery stiffness in a multiethnic population. Increased carotid artery stiffness may, in part, explain a high risk of stroke among individuals with the metabolic syndrome. PMID:20536608

    Abstract Cervical spine manipulation (CSM) is a commonly spinal manipulative therapies for the relief of cervical spine-related conditions worldwide, but its use remains controversial. CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy. A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, although the patient remained conscious, he could not speak but could communicate with the surrounding by blinking or moving his eyes, and turned to complete quadriplegia, complete facial and bulbar palsy, dyspnea at 4 hours after admission. He was diagnosed with LIS. Then, the patient was received cervical and brain computed tomography angiography that showed bilateral VAD. Aortocranial digital subtraction angiography showed vertebrobasilar thrombosis, blocking left vertebral artery, and stenosis of right vertebral artery. The patient was treated by using emergency arterial embolectomy and followed by antiplatelet therapy and supportive therapy in the intensive care unit and a general ward. Twenty-seven days later, the patient's physical function gradually improved and discharged but still left neurological deficit with muscle strength grade 3/5 and hyperreflexia of limbs. Our findings suggested that CSM might have potential severe side-effect like LIS due to bilaterial VAD, and arterial embolectomy is an important treatment choice. The practitioner must be aware of this complication and should give the patients informed consent to CSM, although not all stroke cases temporally related to SCM have pre-existing craniocervical artery dissection.

Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy.A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, although the patient remained conscious, he could not speak but could communicate with the surrounding by blinking or moving his eyes, and turned to complete quadriplegia, complete facial and bulbar palsy, dyspnea at 4 hours after admission. He was diagnosed with LIS. Then, the patient was received cervical and brain computed tomography angiography that showed bilateral VAD. Aortocranial digital subtraction angiography showed vertebrobasilar thrombosis, blocking left vertebral artery, and stenosis of right vertebral artery. The patient was treated by using emergency arterial embolectomy and followed by antiplatelet therapy and supportive therapy in the intensive care unit and a general ward. Twenty-seven days later, the patient's physical function gradually improved and discharged but still left neurological deficit with muscle strength grade 3/5 and hyperreflexia of limbs.Our findings suggested that CSM might have potential severe side-effect like LIS due to bilaterial VAD, and arterial embolectomy is an important treatment choice. The practitioner must be aware of this complication and should give the patients informed consent to CSM, although not all stroke cases temporally related to SCM have pre-existing craniocervical artery dissection.

    Background: Popliteal artery entrapment is an uncommon clinical entity that occurs due to compression of the popliteal artery by adjacent muscle and tendinous structures. Early diagnosis should be established through a combined approach of careful physical examination and history-taking, duplex ultrasonography, and CT angiography. Patients and methods: We have studied retrospectively 16 patients of popliteal artery entrapment syndrome, 9 men and 7 women. All patients were scanned with a scanner Picker PQ 5000 after bolus injection of nonionic contrast medium and they all underwent a two-part examination first, with the knee in a neutral position, and, second, with the knee hyperextended. Results: At the second phase of the examination 3 patients showed normal findings, 10 patients have shown mild stenosis of the popliteal artery or more severe stenosis due to compression, 2 patients have exhibited bilateral stenosis and 1 patient has also showed popliteal venous compression Conclusion: CT angiography images and three-dimensional images are useful not only for depiction of the arterial changes but also identification of the abnormal anatomic structures responsible for the entrapment.

    Infarction of the spinal cord, particularly in the distribution of the posterior spinal arteries, is rare. Twenty seven cases of posterior spinal artery syndrome have been reported. In all cases, the posterior columns were affected, and in all but two, the lesions were bilateral. Here a 49-year-old woman is reported, who was affected with lumbar cord infarction in the distribution of the posterior spinal arteries, diagnosed by MRI and clinical presentation. This case is of special interest because of sparing of the posterior columns and the unilateral nature of the lesion, even though the infarction occurred in the distribution of the posterior spinal arteries.

    We report a 38-year-old patient who presented with pulmonary hypertension and right ventricular dysfunction due to pulmonary artery stenoses as a manifestation of Williams syndrome, mimicking chronic thromboembolic pulmonary hypertension. The patient was treated with balloon angioplasty and stent implantation. Short-term follow-up showed a good clinical result with excellent patency of the stents but early restenosis of the segments in which only balloon angioplasty was performed. These stenoses were subsequently also treated successfully by stent implantation. Stent patency was observed 3 years after the first procedure.

  5. Friable but treatable: coronary artery dissections in Ehlers-Danlos syndrome.

    2013-01-01

    Vascular Ehlers-Danlos syndrome is a rare connective tissue disorder associated with arterial dissection or rupture. Percutaneous coronary intervention (PCI) is often critical in patients with this syndrome because their coronary arteries are prone to dissection, enhancing the risk of stent borders dissection when conventional stent deployment pressures are used. Coronary artery bypass graft (CABG) treatment for these patients may also raise concerns because the left internal mammary artery is probably friable. Therefore, coronary artery revascularization in vascular Ehlers-Danlos syndrome either using PCI or CABG is challenging due to the arteries friability. A small number of cases have been published describing the friability of the vessels and associated complications; nevertheless, the optimum treatment remains unclear. We report the case of a 54-year-old woman treated successfully with PCI and CABG in two different acute coronary syndrome episodes, in which specific technical issues related to both procedures were decisive.

    We herein report a case of phlegmonous gastritis secondary to superior mesenteric artery syndrome. An 80-year-old woman visited the hospital emergency department with the chief complaints of epigastric pain and vomiting. She was hospitalized urgently following the diagnosis of superior mesenteric artery syndrome based on abdominal computed tomography findings. Conservative therapy was not effective, and phlegmonous gastritis was diagnosed based on the findings of upper gastrointestinal endoscopy and biopsy performed on the 12th day of the disease. Undernutrition and reduced physical activity were observed on hospital admission, and proactive nutritional therapy with enteral nutrition was started. An upper gastrointestinal series, performed approximately 1 month later, confirmed the persistence of strictures and impaired gastric emptying. Because conservative therapy was unlikely to improve oral food intake, open total gastrectomy was performed on the 94th day of the disease. Examination of surgically resected specimens revealed marked inflammation and fibrosis, especially in the body of the stomach. Following a good postoperative recovery, the patient was able to commence oral intake and left our hospital on foot approximately 1 month after surgery. PMID:27489695

    Stroke and other neurovascular derangements are main causes of global death. They, along with spinal cord injuries, are responsible for being the principal cause of disability due to neurological and cognitive problems. These problems then lead to a burden on scarce financial resources and societal care facilities as well as have a profound effect on patients' families. The mechanism of action in these debilitating diseases is complex and unclear. An important component of these problems arises from derangement of blood vessels, such as blockage due to clotting/embolism, endothelial dysfunction, and overreactivity to contractile agents, as well as alteration in endothelial permeability. Moreover, the cerebro-vasculature (large vessels and arterioles) is involved in regulating blood flow by facilitating auto-regulatory processes. Moreover, the anterior (middle cerebral artery and the surrounding region) and posterior (basilar artery and its immediate locality) regions of the brain play a significant role in triggering the pathological progression of ischemic stroke particularly due to inflammatory activity and oxidative stress. Interestingly, modifiable and non-modifiable cardiovascular risk factors are responsible for driving ischemic and hemorrhagic stroke and spinal cord injury. There are different stroke animal models to examine the pathophysiology of middle cerebral and basilar arteries. In this context, arterial myography offers an opportunity to determine the etiology of vascular dysfunction in these diseases. Herein, we describe the technique of pressure myography to examine the reactivity of cerebral vessels to contractile and vasodilator agents and a prelude to stroke and spinal cord injury.

    In median arcuate ligament syndrome, the root of the celiac artery is compressed and narrowed by the median arcuate ligament of the diaphragm during expiration, causing abdominal angina.Aneurysm may be formed in arteries of the pancreas and duodenum due toa chronic increase in blood flow from the superior mesenteric artery into the celiac arterial region. We report a patient saved by embolization with coils of ruptured aneurysm that developed with markedly dilated anterior inferior pancreaticoduodenal artery due to median arcuate ligament syndrome.

    Anterior spinal artery syndrome is characterised by acute flaccid quadriparesis or paraparesis, disturbance of pain and temperature sensation, and loss of sphincter control. Fibrocartilaginous embolism is a rarely recognised, but important cause of spinal cord infarction. Fibrocartilaginous embolisation usually occurs after minor trauma without major bony lesions, typically with an intervening symptom-free interval and progressive 'stroke-in-evolution' course. There is evidence that the embolus originates from the intervertebral disc, but the mechanism whereby disc fragments enter the spinal vessels is not well understood. We describe the evolution of MRI findings in a case of anterior spinal artery territory infarction thought to be secondary to fibrocartilaginous embolism. PMID:14747876

    The introduction of seatbelts to legislation has dramatically reduced mortality and morbidity from motor vehicle accidents. However, overtime evidence has emerged of ‘seatbelt syndrome’ (SBS), particularly in the paediatric population. The report describes the diagnosis and management of this rare injury in a 12-year-old boy who sustained a chance lumbar fracture and mesenteric tear resulting in small bowel obstruction. His stay was subsequently complicated by superior mesenteric artery (SMA) syndrome. This is the first documented case of SBS with SMA syndrome. High index of suspicion and continuity of care, particularly in the setting of a ‘seatbelt sign’, is paramount to timely diagnosis and management. PMID:26564612

    Pneumonia is the leading cause of death after acute spinal cord injury and is associated with poor neurological outcome. In contrast to the current understanding, attributing enhanced infection susceptibility solely to the patient's environment and motor dysfunction, we investigate whether a secondary functional neurogenic immune deficiency (spinal cord injury-induced immune deficiency syndrome, SCI-IDS) may account for the enhanced infection susceptibility. We applied a clinically relevant model of experimental induced pneumonia to investigate whether the systemic SCI-IDS is functional sufficient to cause pneumonia dependent on spinal cord injury lesion level and investigated whether findings are mirrored in a large prospective cohort study after human spinal cord injury. In a mouse model of inducible pneumonia, high thoracic lesions that interrupt sympathetic innervation to major immune organs, but not low thoracic lesions, significantly increased bacterial load in lungs. The ability to clear the bacterial load from the lung remained preserved in sham animals. Propagated immune susceptibility depended on injury of central pre-ganglionic but not peripheral postganglionic sympathetic innervation to the spleen. Thoracic spinal cord injury level was confirmed as an independent increased risk factor of pneumonia in patients after motor complete spinal cord injury (odds ratio = 1.35, P < 0.001) independently from mechanical ventilation and preserved sensory function by multiple regression analysis. We present evidence that spinal cord injury directly causes increased risk for bacterial infection in mice as well as in patients. Besides obvious motor and sensory paralysis, spinal cord injury also induces a functional SCI-IDS ('immune paralysis'), sufficient to propagate clinically relevant infection in an injury level dependent manner.

    PubMed

    2013-01-01

    Pulmonary arterial hypertension (PAH) syndrome in broilers (also known as ascites syndrome and pulmonary hypertension syndrome) can be attributed to imbalances between cardiac output and the anatomical capacity of the pulmonary vasculature to accommodate ever-increasing rates of blood flow, as well as to an inappropriately elevated tone (degree of constriction) maintained by the pulmonary arterioles. Comparisons of PAH-susceptible and PAH-resistant broilers do not consistently reveal differences in cardiac output, but PAH-susceptible broilers consistently have higher pulmonary arterial pressures and pulmonary vascular resistances compared with PAH-resistant broilers. Efforts clarify the causes of excessive pulmonary vascular resistance have focused on evaluating the roles of chemical mediators of vasoconstriction and vasodilation, as well as on pathological (structural) changes occurring within the pulmonary arterioles (e.g., vascular remodeling and pathology) during the pathogenesis of PAH. The objectives of this review are to (1) summarize the pathophysiological progression initiated by the onset of pulmonary hypertension and culminating in terminal ascites; (2) review recent information regarding the factors contributing to excessively elevated resistance to blood flow through the lungs; (3) assess the role of the immune system during the pathogenesis of PAH; and (4) present new insights into the genetic basis of PAH. The cumulative evidence attributes the elevated pulmonary vascular resistance in PAH-susceptible broilers to an anatomically inadequate pulmonary vascular capacity, to excessive vascular tone reflecting the dominance of pulmonary vasoconstrictors over vasodilators, and to vascular pathology elicited by excessive hemodynamic stress. Emerging evidence also demonstrates that the pathogenesis of PAH includes characteristics of an inflammatory/autoimmune disease involving multifactorial genetic, environmental, and immune system components.

Lumbosacral magnetic resonance imaging (MRI) demonstrated no lesion at this level, while cervical MRI showed a T2-hyperintense lesion in the middle-right anterolateral region of the cervical spinal cord, which may explain the symptoms by involving the anterior spinothalamic tract. We suggest that in cases with cauda equina syndrome presentation and normal lumbosacral MRI, a cervicodorsal lesion should be considered during diagnostic assessment. PMID:22740824

    Arterial steal syndrome (ASS) after liver transplantation has been reported. ASS causes arterial hypo-perfusion of the graft liver and devastating consequences. However, the diagnosis tends to be delayed. We present the recognized case of a gastroduodenal artery (GDA) steal syndrome that was diagnosed with intraoperative Doppler ultrasound and treated with GDA ligation during the liver transplantation. The patient had variation of hepatic artery anatomy (low bifurcation of the hepatic artery). Graft liver had the common hepatic artery and aberrant left hepatic artery. Doppler ultrasound of the liver was performed after the arterial reconstruction between the donor common hepatic artery and recipient right hepatic artery. It showed low hepatic arterial flow. There is no backflow bleeding from the donor aberrant left hepatic artery stump. After ligating big GDA, hepatic arterial waveform inside the liver drastically improved and strong backflow bleeding was recognized from the donor left aberrant hepatic artery stump. The current case should show the efficacy of intraoperative Doppler ultrasound of the liver on ASS and alert clinician to ligate GDA to prevent ASS if hepatic arterial flows are suboptimal.

    The authors compare the ability of 5-HT derivatives to stimulate adenylate cyclase in the nervous system with their action on the intensity of the spinal pain syndrome (SPS), induced by the creation of a generator of pathologically enhanced excitation in the lumbar segments of the spinal cord of rats. An SPS was induced in rats by applying the sodium salt of benzylpenicillin to the dorsal surface of the lumbar segments of the spinal cord. The effect of 5-HT derivatives on activity of serotonin-sensitive adenylate cyclase was estimated from the change in cAMP concentration in the synaptosomes. During the experiments, the disintegrated synaptosomes were removed by centrifugation after which the cAMP concentration in the supernatant was determined by means of a kit of reagents for radioligand determination of cAMP. Radioactivity was measured on a scintillation spectrometer.

    The spinal pain syndrome appears in cosmonauts on both short and long-duration missions. This untoward factor may affect body systems functioning and complicate the successful accomplishment of space mission. Purpose of the investigation was to examine the lumbar spine and to elucidate whether its condition relates to the spinal pain development and changes in heart rate variability (HRV) in the microgravity environment. The experiment was conducted in dry immersion as a method of microgravity effects simulation. It was shown that in dry immersion locomotion reproduces the patterns peculiar for significant gravitational unloading. Spinal pain intensity, angles and heights of the lumbar intervertebral discs and HRV were measured in 19 selected volunteers. During the experiment, all the volunteers developed pains in the back that abated gradually. Pain dependence on the height of intervertebral discs and cardiac regulatory mechanisms were investigated.

Sensory dissociation was present with more impairment of pain than touch or proprioception. The loss of pain sensation was complete in seven patients, but was incomplete in the other six subjects four of whom showed major motor recovery. The major point of interest of this study is to show that patients who retain not only touch but also pain sensation have a definitely better prognosis for neurological recovery. PMID:7290729

    We have described 13 spinal cord injury patients with a complaint of diffuse, ongoing dysesthesias below the level of the lesion, which are burning in quality, and usually functionally limiting. Quantitative sensory and neurophysiological testing revealed relative preservation of the dorsal column functions in comparison to absence of spinothalamic system mediated functions. On the basis of these findings, we are speculating that such an imbalance between the spinothalamic and dorsal column systems is the main underlying mechanism of dysesthesias as a central nervous system misinterpretation of residual peripheral input.

    The synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome includes a group of chronic, relapsing, inflammatory musculoskeletal disorders with similar manifestations, in particular synovitis, hyperostosis, and osteitis, which may or may not be associated with neutrophilic skin eruptions such as palmoplantar pustulosis and acne conglobata. The syndrome occurs at any age, can involve any skeletal site, and its imaging appearances are variable, depending on the stage/age of the lesion and imaging method. The diagnosis is difficult if there is no skin disease. Awareness of the imaging appearances, especially in the spine, may help the radiologist in avoiding misdiagnosis (e.g., infection, tumor) and unnecessary invasive procedures, while facilitating early diagnosis and selection of an effective treatment. In this article, we provide an overview of the radiological appearances of SAPHO syndrome, focusing on the magnetic resonance imaging findings of vertebral involvement, and present relevant clinical and pathological features that assist early diagnosis.

    This pictorial illustration demonstrates various aspects of arterial tortuosity syndrome (ATS) obtained predominantly from a multiple detector computed tomography (MDCT) examination of a patient. In addition, a comprehensive review of typical multi-modality imaging observations in patients with ATS is presented along with a description of a few imaging signs. Non-invasively obtained, conclusive information is required in patients with ATS in view of the fragile vascular structures involved. An amazing wealth of information can be obtained by reviewing the volumetric data sets of MDCT examination. In the context of incomplete clinical information or remote reading of radiographic examination with inadequate clinical details, ability to “image data mine” the hidden, unexplored information may be vastly useful. The role of MDCT as a single modality of evaluation in ATS is highlighted. PMID:25250193

    We investigated the effect of high spinal anesthesia on postoperative delirium in opium dependent patients undergoing coronary artery bypass grafting (CABG). The study was conducted in a tertiary referral university hospital on a population of 60 opium dependent patients undergoing CABG surgery. Patients were divided into two groups based on anesthesia protocol. One group were given general anesthesia (GA Group), the other group additionally received intrathecal morphine and bupivacaine (SGA Group). Postoperative delirium (POD) was defined as the main outcome of interest. Incidence of POD was significantly higher in patients of GA Group as compared with those in SGA Group (47% and 17% for GA and SGA respectively; P-value = 0.01). Time to extubation was on average 2.2 h shorter in SGA than in GA (7.1 h and 9.3 h respectively, P-value < 0.001). Intrathecal morphine and bupivacaine reduced the risk of POD after CABG in a population of opium dependent patients. PMID:26455008

    Impaired hepatic arterial perfusion after orthotopic liver transplantation (OLT) may lead to ischemic biliary tract lesions and graft-loss. Hampered hepatic arterial blood flow is observed in patients with hypersplenism, often described as arterial steal syndrome (ASS). However, arterial and portal perfusions are directly linked via the hepatic arterial buffer response (HABR). Recently, the term 'splenic artery syndrome' (SAS) was coined to describe the effect of portal hyperperfusion leading to diminished hepatic arterial blood flow. We retrospectively analyzed 650 transplantations in 585 patients. According to preoperative imaging, 78 patients underwent prophylactic intraoperative ligation of the splenic artery. In case of postoperative SAS, coil-embolization of the splenic artery was performed. After exclusion of 14 2nd and 3rd retransplantations and 83 procedures with arterial interposition grafts, SAS was diagnosed in 28 of 553 transplantations (5.1%). Twenty-six patients were treated with coil-embolization, leading to improved liver function, but requiring postinterventional splenectomy in two patients. Additionally, two patients with SAS underwent splenectomy or retransplantation without preceding embolization. Prophylactic ligation could not prevent SAS entirely (n = 2), but resulted in a significantly lower rate of complications than postoperative coil-embolization. We recommend prophylactic ligation of the splenic artery for patients at risk of developing SAS. Post-transplant coil-embolization of the splenic artery corrected hemodynamic changes of SAS, but was associated with a significant morbidity. PMID:20180930

    Spinal cord stimulation as treatment of chronic low back pain via neuromodulation has been frequently performed in recent years. The dorsal column is stimulated by an electrode placed at the epidural region. In the case presently described, subcutaneous lead was implanted in a patient with failed back syndrome after spinal cord stimulation was inadequate to treat back and gluteal pain. A 65-year-old male had undergone surgery to treat lumbar disc herniation, after which he received physical therapy and multiple steroid injections due to unrelieved pain. He was admitted to the pain clinic with pain radiating to right gluteal muscle and leg. Spinal cord stimulation was performed and, as pain was not relieved, subcutaneous lead was applied to the right cluneal nerve distribution. Following treatment, the patient scored 1-2 on visual analog scale. Pain had been reduced by over 80%. Octad electrode was placed between T8 and T10 vertebrae after Tuohy needle was introduced to intervertebral area between L1 and L2. Paresthesia occurred in the right extremity. Boundaries were determined by area of right gluteal region in which paresthesia did not occur. Octad electrode was placed subcutaneously after vertical line was drawn from center point. Paresthesia occurred throughout the region. Pulse wave was 390-450 msec; frequency was 10-30 Hz. Subcutaneous electrode replacement is effective additional therapy when pain is not relieved by spinal cord stimulation. PMID:27225614

A 78-year-old woman with severe disability due to degenerative lumbar spondylosis after laminectomy was treated with transpsoas lumbar interbody fusion from L1 to L4 and posterior spinal fusion from T10 to pelvis. She developed confusion and bilateral visual loss on postoperative day 7. A second patient, a 51-year-old woman with progressive pain and decompensation caused by adult scoliosis, was treated with posterior spinal fusion from T3 to pelvis and interbody fusion from L4 to S1 via a presacral interbody fusion approach. She developed bilateral visual loss on postoperative day 15. Both patients achieved a complete recovery of their vision after medical management of PRES. Timely diagnosis of PRES and prompt intervention allow for a good patient prognosis and complete recovery of eyesight. PMID:26566564

    Behcet's disease is a multisystemic vasculitis of unknown etiology with a chronic relapsing course. Vasculitis in Behcet's disease with predominant vascular involvement is the only vasculitis that affects both arteries and veins of any size. Involvement of the renal artery and inferior vena cava is rare among the arteries and veins, respectively. When disease affect the veins, it is in the form of thrombosis. Arterial complications include aneurysms, stenosis and occlusions. Both rupture of arterial aneurysm and occlusion of suprahepatic veins, causing Budd-Chiari syndrome, are associated with a high mortality rate. Vascular involvement is more common in male patients than in female patients. Men and patients with a younger age of onset present with a more severe prognosis. In this case report, we describe a very rare cause of intrarenal arterial aneurysm's rupture with previous Budd-Chiari syndrome due to Behcet's disease and successful angiographic embolization of actively bleeding aneurysm.

    Background Baastrup's Syndrome is a condition that occurs when there is abnormal contact between two adjacent spinous processes resulting in back pain. An alteration in lumbar spinal alignment and/or adjacent segment compensatory motion is thought to be potential causative factors. The objective of this study was to present a case series of what appears to be iatrogenic Baastrup's Syndrome as a mid-to-late term complication following anterior lumbar interbody surgery. Methods A retrospective chart review was performed of all patients undergoing anterior lumbar surgery for either fusion or disc replacement to determine the prevalence of Baastrup's Syndrome. Results Over a 12-year period, 855 patients who had undergone an anterior approach for lumbar spine surgery were identified. Of them 8 patients with evidence of Baastrup's Syndrome were found; this demonstrated a prevalence of 0.9%. Diagnostic injection was a helpful clinical tool in confirming the diagnosis of iatrogenic Baastrup's Syndrome. The partial removal of the impinging spinous processes resulted in excellent clinical relief. Conclusions Iatrogenic Baastrup's Syndrome may be an iatrogenic result of anterior lumbar surgery in small group of patients. Spinous process excision is a suggested treatment option. Further studies are necessary to explore the above phenomenon. This study is a Level 3 retrospective case series. PMID:26767158

    Life expectancy in vascular Ehlers-Danlos syndrome (EDS) is shortened due to spontaneous rupture of arteries, the colon and the gravid uterus. Two adolescent males with vascular EDS illustrate rapid progression of arterial aneurysms, dissections, and rupture. Radiologic imaging played an important role in initially diagnosing and monitoring the evolution of arterial involvement. Both prophylactic and emergency management remain largely ineffective in this connective tissue disorder; however, noninvasive imaging may provide important prognostic information. PMID:22065459

  13. Role of spinal V1a receptors in regulation of arterial pressure during acute and chronic osmotic stress.

    Vasopressinergic neurons in the paraventricular nucleus project to areas in the spinal cord from which sympathetic nerves originate. This pathway is hypothesized to be involved in the regulation of mean arterial pressure (MAP), particularly under various conditions of osmotic stress. Several studies measuring sympathetic nerve activity support this hypothesis. However, the evidence that spinal vasopressin influences MAP under physiological or pathophysiological conditions in conscious animals is limited. The purpose of this study was to investigate, in conscious rats, if the increases in MAP during acute or chronic osmotic stimuli are due to activation of spinal vasopressin (V1a) receptors. Three conditions of osmotic stress were examined: acute intravenous hypertonic saline, 24- and 48-h water deprivation, and 4 wk of DOCA-salt treatment. Rats were chronically instrumented with an indwelling catheter for intrathecal injections and a radiotelemeter to measure MAP. In normotensive rats, intrathecal vasopressin and V1a agonist increased MAP, heart rate, and motor activity; these responses were blocked by pretreatment with an intrathecal V1a receptor antagonist. However, when the intrathecal V1a antagonist was given during the three conditions of osmotic stress to investigate the role of "endogenous" vasopressin, the antagonist had no effect on MAP, heart rate, or motor activity. Contrary to the hypothesis suggested by previous studies, these findings indicate that spinal V1a receptors are not required for elevations of MAP under conditions of acute or chronic osmotic stress in conscious rats.

    The metabolic syndrome (MetS) is associated with a threefold increase risk of cardiovascular disease (CVD) mortality partly due to increased arterial stiffening. We compared the effects of aerobic exercise training on arterial stiffening/mechanics in MetS subjects without overt CVD or type 2 diabetes. MetS and healthy control (Con) subjects underwent 8 wk of exercise training (ExT; 11 MetS and 11 Con) or remained inactive (11 MetS and 10 Con). The following measures were performed pre- and postintervention: radial pulse wave analysis (applanation tonometry) was used to measure augmentation pressure and index, central pressures, and an estimate of myocardial efficiency; arterial stiffness was assessed from carotid-femoral pulse-wave velocity (cfPWV, applanation tonometry); carotid thickness was assessed from B-mode ultrasound; and peak aerobic capacity (gas exchange) was performed in the seated position. Plasma matrix metalloproteinases (MMP) and CVD risk (Framingham risk score) were also assessed. cfPWV was reduced (P < 0.05) in MetS-ExT subjects (7.9 ± 0.6 to 7.2 ± 0.4 m/s) and Con-ExT (6.6 ± 1.8 to 5.6 ± 1.6 m/s). Exercise training reduced (P < 0.05) central systolic pressure (116 ± 5 to 110 ± 4 mmHg), augmentation pressure (9 ± 1 to 7 ± 1 mmHg), augmentation index (19 ± 3 to 15 ± 4%), and improved myocardial efficiency (155 ± 8 to 168 ± 9), but only in the MetS group. Aerobic capacity increased (P < 0.05) in MetS-ExT (16.6 ± 1.0 to 19.9 ± 1.0) and Con-ExT subjects (23.8 ± 1.6 to 26.3 ± 1.6). MMP-1 and -7 were correlated with cfPWV, and both MMP-1 and -7 were reduced post-ExT in MetS subjects. These findings suggest that some of the pathophysiological changes associated with MetS can be improved after aerobic exercise training, thereby lowering their cardiovascular risk. PMID:24744384

Magnetic resonance imaging revealed acute infarctions in the bilateral medial frontal regions but not in the brainstem or spinal cord.

    An 82-year-old woman who had received two operations for lumbar spinal stenosis was treated successfully for persistent nocturnal leg cramps with lumbar sympathetic ganglion block. The stent in the right popliteal artery improved cramps again following the recurrence one month after the block. The head up position in bed against gastroesophageal reflux was found injurious at the time of second recurrence one year after stenting. After the correction of lying position, her legs were in good condition for over one year. Cramps in this case might be caused by disturbances of blood flow supply for motor nerves of the legs by obstructive arterial sclerosis of the nerve injured from root compression. PMID:27188122

    Objective: To describe a novel manifestation of lower motor neuron disease in patients with well-controlled HIV infection. Methods: A retrospective study was performed to identify HIV-positive individuals with acute, painful lower motor neuron diseases. Results: Six patients were identified with HIV and lower motor neuron disease. Two patients met the inclusion criteria of well-controlled, chronic HIV infection and an acute, painful, unilateral lower motor neuron paralytic syndrome affecting the distal portion of the upper limb. These patients had segmental T2-hyperintense lesions in the central gray matter of the cervical spinal cord on MRI. One patient stabilized and the second patient improved with immunomodulatory therapy. Conclusions: This newly described syndrome expands the clinical spectrum of lower motor neuron diseases in HIV.

    A 73-year-old man was admitted for evaluation of sudden onset of dizziness, bilateral shoulder pain, and brachial diplegia. Neurological examination revealed severe bilateral weakness of the triceps brachii, wrist flexor, and wrist extensor muscles. There was no paresis of the lower limbs. His gait was ataxic. Pinprick and temperature sensations were diminished at the bilateral C6-C8 dermatomes. Vibration and position senses were intact. An MRI of the head revealed a right cerebellar infarction and occlusion of the right vertebral artery. An MRI of the cervical spine on T₂ weighted imaging (T₂WI) showed cord compression at the C3/4-C5/6 level secondary to spondylotic degeneration without any intramedullary signal changes of the cord. On the following day, however, high-signal lesions on T₂WI appeared in the C5-C6 spinal cord, suggesting cord infarction. Unilateral vertebral artery occlusion does not usually result in cervical cord infarction because of anastomosis of arteries. Because of the long-term mechanical compression in our case, it was likely that cervical cord ischemia was present before the onset of symptoms. On the basis of chronic cord compression, our case suggests that occlusion of a unilateral vertebral artery could cause cervical cord infarction. PMID:22790805

  3. Spinal cord stimulation as a treatment for refractory neuropathic pain in tethered cord syndrome: a case report

    PubMed Central

    2010-01-01

    Introduction The spinal cord is a target for many neurosurgical procedures used to treat chronic severe pain. Neuromodulation and neuroablation are surgical techniques based on well-known specific anatomical structures. However, anatomical and electrophysical changes related to the tethered spinal cord make it more difficult to use these procedures. Case presentation We report the case of a 37-year-old Caucasian woman who had several surgical interventions for tethered cord syndrome. These interventions resulted in severe neuropathic pain in her lower back and right leg. This pain was treated by spinal cord stimulation using intra-operative sensory mapping, which allowed the cord's optimal placement in a more caudal position. Conclusion The low-voltage and more caudally placed electrodes are specific features of this treatment of tethered cord syndrome. PMID:20184768

    Arterial tortuosity syndrome (ATS) is a rare hereditary disorder with variable clinical presentation including tortuosity and elongation of the major arteries, often associated with pulmonary artery stenosis, pulmonary hypertension, and skin and joint laxity, suggestive of a connective tissue disorder. ATS is transmitted in an autosomal recessive mode, but the causal gene is unknown. We report an Italian pedigree with three inbred families in which five patients show signs of ATS. In particular, four adult patients present arterial tortuosity and elongation of the main arteries. Two of these patients, with the most severe degree of arterial tortuosity, also show severe peripheral stenosis of the main pulmonary artery. The fifth young patient shows a severe pulmonary valve stenosis in the absence of arterial tortuosity. All patients show signs of Ehlers-Danlos syndrome (EDS): soft skin with abundant subcutaneous tissue and joint laxity, hernias, and disorganization of the extracellular matrix (ECM) of fibronectin (FN) and of actin microfilaments in cultured skin fibroblasts. Linkage analysis of the genes involved in EDS and other connective tissue disorders, excluded COL1A1, COL1A2, COL2A1, COL3A1, COL5A1, COL5A2, COL5A3, COL6A1, COL6A2, ADAMTS2, ELN, FN1, TNXA, and TNXB as candidate genes in the family under study, thus indicating that ATS is a distinct clinical and molecular entity.

    It is generally considered that the genesis of myelopathy associated with the degenerative conditions of the spine may result from both mechanical compression and circulatory disturbance. Many references about spinal cord tissue ischemic damage can be found in the literature, but not detailed studies about spinal cord microvasculature damage related to congestion or blood permeability. This study investigates the effect of ischemia and congestion on the spinal cord using an in vivo model. The aorta was clamped as an ischemia model of the spinal cord and the inferior vena cava was clamped as a congestion model at the 6th costal level for 30 min using forceps transpleurally. Measurements of blood flow, partial oxygen pressure, and conduction velocity in the spinal cord were repeated over a period of 1 h after release of clamping. Finally, we examined the status of blood-spinal cord barrier under fluorescence and transmission electron microscope. Immediately after clamping of the inferior vena cava, the central venous pressure increased by about four times. Blood flow, oxygen tension and action potential were more severely affected by the aorta clamping; but this ischemic model did not show any changes of blood permeability in the spinal cord. The intramedullar edema was more easily produced by venous congestion than by arterial ischemia. In conclusions, venous congestion may be a preceding and essential factor of circulatory disturbance in the compressed spinal cord inducing myelopathy. PMID:22912247

    Monochorionic multiple pregnancy has a higher risk for obstetric complications, including those due to the development of twin-to-twin transfusion syndrome and reversed arterial perfusion syndrome (TRAP sequence). The latter occurs in 0.1% of all monochorionic pregnancies. The basis for TRAP sequence is a relationship between arterial and venous anastomoses from the appropriate placental areas, causing a recipient fetus to develop at the expense of a donor fetus. The presence of abnormal anastomoses is considered to be a main cause of acardia. The prognosis for a donor fetus is also unfavorable: the mortality rates in the absence of intrauterine correction are as high as 55%. PMID:27600783

She was transferred to our facility with acute coronary syndrome complicated by cardiogenic shock. Angiography demonstrated giant bilateral coronary aneurysms and complete occlusion of the left anterior descending (LAD) artery. Emergent coronary artery bypass grafting was performed. Coronary artery bypass grafting is the preferred approach for addressing giant coronary aneurysms. Intervention on the aneurysm varies in the literature. Aggressive revascularization is recommended in the non-Kawasaki/nonatherosclerotic aneurysm patient, and ligation should be performed in patients with thromboembolic phenomena. PMID:27000621

    Spinal muscular atrophy with respiratory distress syndrome (SMARD1) is a rare cause of early infantile respiratory failure and death. No cases have been currently described from India. Two low-birth-weight infants presented prior to 6 months of age with recurrent apnea and respiratory distress. Both required prolonged ventilation, and had distal arthrogryposis and diaphragmatic eventration. Nerve conduction study revealed motor sensory axonopathy. Genetic testing confirmed mutations in immunoglobulin mu binding protein (IGHMBP2). These two cases establish presence of SMARD1 in our population. Both infants died on discontinuation of ventilation. Antenatal diagnoses done in one pregnancy. Though rare, high index of suspicion is essential in view of poor outcome and aid antenatal counseling.

    It is somewhat unexpected to have headaches in patients with idiopathic normal pressure hydrocephalus (INPH) for which the treatment is drainage of cerebrospinal fluid (CSF) using shunt. Moreover, intracranial hypotension syndrome (IHS) can be a challenging diagnosis, as CSF leak may be difficult to confirm as imaging findings can be normal. This report describes a woman with INPH who developed symptoms of IHS after a spinal tap test. There might be cases with IHS, like our case, who do not completely fulfill the current diagnostic criteria in terms of not having any objective evidence of intracranial hypotension but who also could not be explained by other conditions and recovered totally after classical IHS treatment. Current diagnostic criteria for IHS might be revised for those having normal neuroimaging and not accepting lumbar puncture. Nevertheless, when the history, signs, and symptoms strongly suggest IHS even with normal imaging, treatment should be started immediately. PMID:25762438

    The sympathetic block is widely used for treating neuropathic pain such as complex regional pain syndrome (CRPS). However, single sympathetic block often provides only short-term effect. Moreover, frequent procedures for sympathetic block may increase the risk of complications. The use of epidural route may be limited by concern of infection in case of previous implantation of the spinal cord stimulation (SCS). In contrast, a continuous sympathetic block can be administered without such concerns. The continuous thoracic sympathetic block (TSGB) has been used to treat the ischemic disease and other neuropathic conditions such as postherpetic neuralgia. We administered continuous thoracic sympathetic block using catheter in CRPS patients who underwent SCS implantations and achieved desirable outcomes. We believe a continuous sympathetic block is a considerable option before performing neurolysis or radiofrequency rhizotomy and even after SCS implantation.

    Congenital single coronary artery is commonly associated with complex congenital heart diseases and manifests in infancy or childhood. But isolated single coronary artery is a rare congenital anomaly which can present as acute coronary syndrome in adults. The aim of the work is to discuss on isolated single coronary artery in two adults presenting as acute coronary syndrome. The first case underwent coronary angiography (CAG) through right radial route, but switched over to femoral for confirmation of diagnosis and due to radial spasm. An aortic root angiogram was done to rule out presence of any other coronary ostia. It revealed a single coronary artery originating from right sinus of valsalva. After giving rise to posterior descending artery branch at crux, it continued in the atrioventricular groove to the anterior basal surface of the heart and traversed as anterior descending artery. There was no atheromatous occlusive stenosis. This is R-I type single coronary artery as per Lipton classification. In the second case, angiography was completed through right radial route. It revealed a single coronary artery arising from right aortic sinus. Anterior descending and circumflex branch were originating from proximal common trunk of the single coronary artery and supplying the left side of the heart. The right coronary artery has diffuse atheromatous disease without significant stenosis in any major branch. This is R-III C type as per Lipton classification. A coronary anomaly of both origin and course is very rare. It may be encountered in adults evaluated for atherosclerotic coronary heart disease. Knowledge and understanding of anatomical types of this congenital anomaly will reduce time, anxiety, complications during CAG and cardiac surgery. PMID:25075168

    Ehlers-Danlos syndrome type IV is a life-threatening genetic connective tissue disorder. We report a 24-year-old woman with EDS-IV who presented with metachronous bilateral aneurysms/pseudoaneurysms of the posterior tibial arteries 15 months apart. Both were treated successfully with transarterial coil embolization from a distal posterior tibial approach.

    Any disease process decreasing the angle between the superior mesenteric artery and the abdominal aorta can result in the external compression of the duodenum and subsequent intestinal obstruction. This unusual type of intestinal obstruction known as superior mesenteric artery syndrome is a well-recognized clinical entity. It is diagnosed radiologically by an abrupt, vertical cutoff of barium flow in the third portion of the duodenum. The management is primarily medical but occasionally surgical correction is required. Herein, the diagnosis of superior mesenteric artery syndrome was made in an incomplete quadriplegic woman who had recently undergone surgical resection of an arteriovenous malformation in the cervical cord. This case was managed successfully with gastrointestinal decompression, proper positioning in the side-lying position, and adequate nutrition. PMID:3631039

    Background Pulmonary arterial hypertension, also known as Ascites syndrome (AS), remains a clinically challenging disease with a large impact on both humans and broiler chickens. Pulmonary arterial remodeling presents a key step in the development of AS. The precise molecular mechanism of pulmonary artery remodeling regulating AS progression remains unclear. Methodology/Principal Findings We obtained pulmonary arteries from two positive AS and two normal broilers for RNA sequencing (RNA-seq) analysis and pathological observation. RNA-seq analysis revealed a total of 895 significantly differentially expressed genes (DEGs) with 437 up-regulated and 458 down-regulated genes, which were significantly enriched to 12 GO (Gene Ontology) terms and 4 KEGG (Kyoto Encyclopedia of Genes and Genomes) pathways (Padj<0.05) regulating pulmonary artery remodeling and consequently occurrence of AS. These GO terms and pathways include ribosome, Jak-STAT and NOD-like receptor signaling pathways which regulate pulmonary artery remodeling through vascular smooth cell proliferation, inflammation and vascular smooth cell proliferation together. Some notable DEGs within these pathways included downregulation of genes like RPL 5, 7, 8, 9, 14; upregulation of genes such as IL-6, K60, STAT3, STAT5 Pim1 and SOCS3; IKKα, IkB, P38, five cytokines IL-6, IL8, IL-1β, IL-18, and MIP-1β. Six important regulators of pulmonary artery vascular remodeling and construction like CYP1B1, ALDH7A1, MYLK, CAMK4, BMP7 and INOS were upregulated in the pulmonary artery of AS broilers. The pathology results showed that the pulmonary artery had remodeled and become thicker in the disease group. Conclusions/Significance Our present data suggested some specific components of the complex molecular circuitry regulating pulmonary arterial remodeling underlying AS progression in broilers. We revealed some valuable candidate genes and pathways that involved in pulmonary artery remodeling further contributing to the AS

    Reversible cerebral vasoconstriction syndrome (RCVS) has been associated with exposure to vasoactive substances and few reports with cervical arterial dissections (CADs). We evaluated a 32-year-old woman with history of depression, migraines without aura, and cannabis use who presented with a thunderclap headache unresponsive to triptans. She was found to have bilateral occipital infarcts, bilateral extracranial vertebral artery dissections, bilateral internal carotid artery dissecting aneurysms, and extensive distal multifocal segmental narrowing of the anterior and posterior intracranial circulation with a "sausage on a string-like appearance" suggestive of RCVS. Subsequently, she was found to have a distal thrombus of the basilar artery, was anticoagulated, and discharged home with no residual deficits. We highlight the potential association of CADs and RCVS. The association of RCVS and a double aortic arch has not been previously reported. PMID:24103665

    The coexistence of polyneuropathy which has the definite clinical and electromyographical findings consistent with Charcot-Marie-Tooth (CMT) syndrome and neurofibromatosis type 1 (NF1) has infrequently been reported. We describe a patient with both CMT and NF1, who had multiple neurofibromas involving the entire spinal neural axis. In addition, he had multiple neurofibromas distributed within the ileopsoas and gluteus muscles and subcutaneous tissues. These lesions were detected readily by MRI and the patient underwent successful surgical resection of the largest tumours compressing bilateral C2 nerve roots. To our knowledge, this is the first reported case of CMT syndrome coexisting with NF1 in which multiple neurofibromas involved the entire spinal nerve roots. We discuss the diagnostic and therapeutic challenges, emphasising the role of MRI and electrophysiology in such cases and provide a literature review. PMID:23853192

    Traumatic causes of orbital apex and superior orbital fissure syndrome are uncommon. The authors present the first case of a traumatic superior orbital fissure syndrome simulating orbital apex syndrome, with loss of vision from posterior ischemic optic neuropathy. A 35-year-old man was initially felt to have a right orbital apex syndrome with left craniofacial and orbital trauma. CT revealed left orbital fractures, a right superior orbital fissure fracture, a retained metallic foreign body in the right sphenoid sinus, and a right frontoparietal subdural hematoma. CT angiography showed a secondary dissection and occlusion of the right internal carotid artery from osseous erosion of the posterolateral wall of the sphenoid sinus. Internal carotid artery dissection is a possible, though rare, cause of ischemic optic neuropathy. The right pseudo-orbital apex syndrome resulted from a mechanical superior orbital fissure syndrome and posterior ischemic optic neuropathy from an internal carotid artery dissection. PMID:25216200

    Traumatic injury to the spinal cord triggers a systemic inflammatory response syndrome (SIRS), in which inflammatory cells from the circulation invade organs such as the liver, lung and kidney, leading to damage of these organs. Our previous study (Gris, et al, Exp. Neurol, 2008) demonstrated that spinal cord injury (SCI) activates circulating neutrophils that then invade the lung and kidney from 2 to 24 h after injury, increasing myeloperoxidase activity, cyclooxygenase-2 and matrix metalloproteinase-9 expression and lipid peroxidation in these organs. The present study was designed to ascertain whether a treatment that limits the influx of leukocytes into the injured spinal cord would also be effective in reducing the SIRS after SCI. This treatment is intravenous delivery of a monoclonal antibody (mAb) against the CD11d subunit of the CD11d/CD18 integrin expressed by neutrophils and monocytes. We delivered the anti-CD11d mAb at 2 h post moderate clip compression SCI at the 4th or 12th thoracic segments and assessed inflammation, oxidative activity and cellular damage within the lung, kidney and liver at 12 h post-injury. In some analyses we compared high and low thoracic injuries to evaluate the importance of injury level on the intensity of the SIRS. After T4 injury, treatment with the anti-integrin mAb reduced the presence of neutrophils and macrophages in the lung, with associated decreases in expression of NF-κB and oxidative enzymes and in the concentration of free radicals in this organ. The treatment also reduced lipid peroxidation, protein nitration and cell death in the lung. The anti-CD11d treatment also reduced the inflammatory cells within the kidney after T4 injury, as well as the free radical concentration and amount of lipid peroxidation. In the liver, the mAb treatment reduced the influx of neutrophils but most of the other measures examined were unaffected by SCI. The inflammatory responses within the lung and kidney were often greater after T4

    White matter hyperintensities (WMH) are defined as cerebral white matter changes presumed to be of vascular origin, bilateral and mostly symmetrical. They can appear as hyperintense on T2-weighted and fluid-attenuated inversion recovery sequences, and as isointense or hypointense on T1-weighted magnetic resonance imaging of the brain. WMH have been focused on because of their clinical importance as a risk factor for cerebrovascular diseases and cognitive impairment. WMH are associated with geriatric syndrome, which is defined by clinical symptoms characteristic of older adults, including cognitive and functional impairment and falls. Cerebral small vessel diseases, such as WMH, might play an important role as risk factors for cerebrovascular diseases, cognitive impairment and geriatric syndrome through the mechanism of arterial stiffness. However, the vascular, physiological and metabolic roles of arterial stiffness remain unclear. Basically, arterial stiffness indicates microvessel arteriosclerosis presenting with vascular endothelial dysfunction. These changes might arise from hemodynamic stress as a result of a "tsunami effect" on cerebral parenchyma. In the present article, we review the clinical characteristics of WMH, focusing particularly on two associations: (i) those between cerebral small vessel diseases including WMH and arterial stiffness; and (ii) those between WMH and geriatric syndrome.

    Objective: Ocular ischemic syndrome is a rare blinding condition generally caused by disease of the carotid artery. We describe a 69-year-old female with a 50 pack-year smoking history with aortic arch syndrome causing bilateral ocular ischemic syndrome. Methods: The patient presented with progressive visual loss and temple pain. Slit lamp biomicroscopy revealed bilateral iris neovascularization. This finding prompted a cardiovascular work up. Panretinal photocoagulation with retrobulbar block was performed in the right eye. Results: A temporal artery biopsy was negative. The carotid duplex ultrasound showed only a 1–39% stenosis. MRA revealed a more proximal occlusion of the aortic branch for which she underwent subclavian carotid bypass surgery. At the one month follow up, the right eye suffered profound vision loss secondary to a central retinal artery occlusion. Conclusion: Ocular neovascularization may be one of the clinical manifestations of aortic arch syndrome. This case also illustrates the limitations of relying solely on carotid duplex ultrasound testing. We caution against overly aggressive panretinal photocoagulation utilizing retrobulbar anesthesia.

    A 58-year-old Caucasian lady presented for severe left internal carotid artery (ICA) stenosis. Two months before she was operated for right carotid endarterectomy (CEA) in another Institution, complicated with internal carotid artery thrombosis and development of transient hemiplegia and aphasia. Postoperative selective DSA showed the development of an abnormal basal meshwork of collateral vessels with typical evidence for moyamoya disease. Preoperative workup in our Institution included cerebral MRI witch showed two ischemic right frontal and parietal lesions. The patient underwent successful stenting of the left ICA. This is the first report of extracranial ICA stenting in a patient with moyamoya syndrome. PMID:23147441

    Williams syndrome (WS) is a developmental disorder characterized by vascular abnormalities such as thickening of the vascular media layer in medium- and large-sized arteries. Supravalvular aortic stenosis (SVAS) and peripheral pulmonary artery stenosis (PPAS) are common vascular abnormalities in WS. The natural course of SVAS and PPAS is variable, and the timing of surgery or intervention is determined according to the progression of vascular stenosis. In our patient, SVAS and PPAS showed rapid concurrent progression within two weeks after birth. We report the early manifestation of SVAS and PPAS in the neonatal period and describe the surgical treatment for stenosis relief. PMID:27066434

Despite the widespread use of revascularization for NSTE-ACS, most patients undergo a percutaneous coronary intervention, whereas a minority of patients undergo coronary artery bypass grafting. Focusing specifically on the USA, the contemporary utilization, preoperative and perioperative considerations, and outcomes of NSTE-ACS patients undergoing coronary artery bypass grafting have not been comprehensively reviewed.

    Context: Somato-sensitive innervation of bowels are maintained by lower segments of spinal cord and the blood supply of the lower spinal cord is heavily dependent on Adamkiewicz artery. Although bowel problems are sometimes seen in subarachnoid hemorrhage neither Adamkiewicz artery spasm nor spinal cord ischemia has not been elucidated as a cause of bowel dilatation so far. Aims: The goal of this study was to study the effects Adamkiewicz artery (AKA) vasospasm in lumbar subarachnoid hemorrhage (SAH) on bowel dilatation severity. Settings and Design: An experimental rabbit study. Materials and Methods: The study was conducted on 25 rabbits, which were randomly divided into three groups: Spinal SAH (N = 13), serum saline (SS) (SS; N = 7) and control (N = 5) groups. Experimental spinal SAH was performed. After 21 days, volume values of descending parts of large bowels and degenerated neuron density of L5DRG were analyzed. Statistical Analysis Used: Statistical analysis was performed using the PASW Statistics 18.0 for Windows (SPSS Inc., Chicago, Illinois). Two-tailed t-test and Mann-Whitney U-tests were used. The statistical significance was set at P < 0.05. Results: The mean volume of imaginary descending colons was estimated as 93 ± 12 cm3 in the control group and 121 ± 26 cm3 in the SS group and 176 ± 49 cm3 in SAH group. Volume augmentations of the descending colons and degenerated neuron density L5DRG were significantly different between the SAH and other two groups (P < 0.05). Conclusion: An inverse relationship between the living neuronal density of the L5DRG and the volume of imaginary descending colon values was occurred. Our findings will aid in the planning of future experimental studies and determining the clinical relevance on such studies. PMID:25972712

    Current guidelines for the care of patients with acute spinal cord injuries (SCIs) recommend maintaining mean arterial pressure (MAP) values of 85-90 mm Hg for 7 days after an acute SCI however, little evidence supports this recommendation. We sought to better inform the relationship between MAP values and neurological recovery. A computer system automatically collected and stored q1 min physiological data from intensive care unit monitors on patients with SCI over a 6-year period. Data for 100 patients with acute SCI were collected. 74 of these patients had American Spinal Injury Association Impairment Scale (AIS) grades determined by physical examination on admission and at time of hospital discharge. Average MAP values as well as the proportion of MAP values below thresholds were explored for values from 120 mm Hg to 40 mm Hg in 1 mm Hg increments; the relationship between these measures and outcome was explored at various time points up to 30 days from the time of injury. A total of 994,875 q1 min arterial line blood pressure measurements were recorded for the included patients amid 1,688,194 min of recorded intensive care observations. A large proportion of measures were below 85 mm Hg despite generally acceptable average MAP values. Higher average MAP values correlated with improved recovery in the first 2-3 days after SCI while the proportion of MAP values below the accepted threshold of 85 mm Hg seemed a stronger correlate, decreasing in strength over the first 5-7 days after injury. This study provides strong evidence supporting a correlation between MAP values and neurological recovery. It does not, however, provide evidence of a causal relationship. Duration of hypotension may be more important than average MAP. It provides support for the notion of MAP thresholds in SCI recovery, and the highest MAP values correlated with the greatest degree of neurological recovery. The results are concordant with current guidelines in suggesting that MAP thresholds

    Irritable bowel syndrome (IBS) is characterized by abdominal pain and changed bowel habits. Spinal cord stimulation (SCS) has been used for treatment of chronic pain syndromes. Animal studies have shown SCS to reduce the reaction to colonic balloon distension, known to be increased in IBS patients. To elucidate the potential for SCS as treatment for IBS, a pilot study was performed. Ten IBS patients (age 26-56 yr) were recruited. A SCS system with a four-polar electrode was implanted at the T5-T8 level. After a 2-wk run-in, a randomized, crossover design SCS during 6 wk was compared with no stimulation, with an ensuing stimulation period for 12 wk; total study period 28 wk. Patients recorded pain level, pain attacks, diarrheas, and global quality of life in a diary. At end of the study patients could choose to retain their SCS system or have it removed. Nine patients completed the whole trial. During stimulation periods the median pain scores were significantly reduced from visual analogue scale (VAS) 7 (4-8) to 3 (2.5-7) and to 4 (2-6) during early and late stimulation periods, respectively (P < 0.03-0.04). Pain attacks were numerically reduced. A few patients reported reduced number of diarrheas. After study termination, six patients chose to retain their SCS system. To conclude, SCS is a minimally invasive treatment option for pain in IBS. With SCS the pain level was reduced though with merely a trend for number of attacks and diarrheas. The efficacy of SCS in IBS pain indicates a possible usefulness in other painful bowel disorders. PMID:25786486

    The Korsakoff syndrome is defined as “an abnormal mental state in which memory and learning are affected out of all proportion to other cognitive functions in an otherwise alert and responsive patient.” Confabulation refers to false or erroneous memories arising, not deliberately, in the context of a neurological amnesia and is often thought of as pathognomonic of the Korsakoff syndrome. Although the exact pathophysiology is unknown, various studies have identified brain lesions in the thalami, mammillary bodies, and frontal cortex. We report a case of a 68-year-old male presenting with acute altered mental status on July 16, 2015. The neuropsychological dysfunctions included prominent Korsakoff's syndrome, which became apparent when the altered mental status resolved. Amnesia was accompanied by prominent confabulation, disorientation, and lack of insight into his own disability. Neuroradiological data indicated that the intralaminar and dorsomedial nuclei in bilateral thalami were infarcted by occlusion of the artery of Percheron. We believe that ours is one of few reported cases of Korsakoff syndrome in a patient with infarction involving the territory of the artery of Percheron. We conclude that bilateral thalamic lesions could cause Korsakoff's syndrome and the intralaminar and dorsomedial nuclei might be important structures in the pathogenesis of confabulation.

    Neurovascular compression is assumed to cause symptoms like trigeminal neuralgia, hemifacial spasm and vestibular paroxysmia. We present a patient with recurrent episodes of transient dysarthria due to isolated right hypoglossal nerve (HN) palsy. We describe the first case of a calcified persistent hypoglossal artery (PHA) as the putative cause of a hypoglossal neurovascular compression syndrome. Our patient received a daily low-dose medication of carbamazepine resulting in complete relief of symptoms. In conclusion, PHA is not only an anatomic variation but also a possible cause of a neurovascular compression syndrome leading to intermittent HN palsy. PMID:23020989

    Acute compartment syndrome of the forearm in newborns is often misdiagnosed and can be disastrous if left untreated. Here, we report a full-term infant of a diabetic mother with underlying heterozygosity for MTHFR C677T and A1298C alleles. A spontaneous thrombosis occurred in the left axillary artery immediately after birth. The patient responded well to anticoagulant (heparin) and thrombolytic (tissue plasminogen activator) agents. After reperfusion of the extremity, acute compartment syndrome developed. Emergent fasciotomy was performed. In this case, effective collaboration between pediatricians and orthopedic surgeons resulted in salvage of the extremity, with good clinical and functional results. PMID:26237661

    We discuss the association between tethered cord syndrome (TCS) and Chiari type 1 malformation (CM1), and report on the surgical outcomes of children with CM1 and TCS who underwent sectioning of the filum terminale (SFT). The relationship between TCS and CM1 is unclear. A retrospective review of 170 consecutive spinal cord detetherings between 2008 and 2012 was performed. We identified 17 children with CM1 who underwent SFT. Information regarding clinical presentation, radiographic findings, surgical procedures, and clinical outcomes was analyzed. A mean tonsillar herniation of 10.0mm (range: 5-21) was noted. Children with a fatty or thickened filum terminale demonstrated a greater amount of tonsillar displacement (p<0.005). A low conus medullaris was found in 12 children and a syrinx was present in three. The preoperative symptoms improved in all children. The postoperative MRI (mean 21.8 months) revealed an unchanged tonsillar position in all but one child. No worsening of neurologic function was noted. Pediatric patients who have both CM1 and TCS, but do not demonstrate classic Chiari-related symptoms, may experience symptomatic improvement after filum terminale sectioning. PMID:26165471

    This case report illustrates the neuroanatomy and neurovascular anatomy of the cervical spinal cord by exploring the pathophysiology of cervical cord infarction secondary to vertebral artery injury. The spinal cord is made up of several important tracts, including the dorsal column medial lemniscus system, corticospinal tracts, and the anterolateral system. Injury to one or more of these pathways can result in localizing neurological symptoms. Also contributing to the complexity of spinal vascular pathophysiology is the considerable variation to the cervical cord vascular anatomy. Understanding spinal cord function and neuroanatomy can aid in prompt diagnosis and management of ischemic cord lesions. In combination with a thorough clinical exam, advanced imaging techniques, such as diffusion tensor imaging, can not only localize the injury but also potentially help predict functional outcome.

    Spinal cord stimulation has become a widely used and efficient alternative for the management of refractory chronic pain that is unresponsive to conservative therapies. Technological improvements have been considerable and the current neuromodulation devices are both extremely sophisticated and reliable in obtaining good results for various clinical situations of chronic pain, such as failed back surgery syndrome, complex regional pain syndrome, ischemic and coronary artery disease. This technique is likely to possess a savings in costs compared with alternative therapy strategies despite its high initial cost. Spinal cord stimulation continues to be a valuable tool in the treatment of chronic disabling pain. PMID:22787543

However, angiographically visible complete SF after bare metal stent (BMS) implantation is extremely rare. Here we report a case of SF of a BMS representing with acute coronary syndrome (ACS). To our knowledge, this is the first report of early fracture of a BMS in the right coronary artery, resulting in ACS. PMID:19042043

    Complex regional pain syndrome (CRPS) associated with acute carpal tunnel syndrome (aCTS) developed in a 38-year-old right-handed man following radial artery cannulation (RAC) during the course of lumbar spine surgery. Inciting events and risk factors that might have led to these complications included: multiple arterial punctures and subsequent hematoma formation, radial artery spasm compounded by aggressive hemostasis, anatomical changes in the wrists related to repetitive manual activities in the workplace, and possible protracted hyperextension of the wrists during perioperative and operative procedure. Although CRPS is considered a rare complication of RAC, the condition is disabling and debilitating, especially when associated with aCTS. PMID:25621693

    We report a case of anomalous left coronary artery from the pulmonary artery (ALCAPA) or Bland-White-Garland syndrome, present the challenges of performing a differential diagnosis, and discuss the treatment of the syndrome. Although ALCAPA is a rare congenital heart disease, it is one of the most common causes of myocardial ischemia in childhood and presents a diagnostic challenge. A four-year-old girl was referred to a pediatric cardiologist for evaluation of mitral valve regurgitation murmur and heart failure. The transthoracic echocardiogram demonstrated the left coronary artery (LCA) not arising from the aorta, presence of coronary collateral circulation, and moderate mitral valve regurgitation. ALCAPA was confirmed using angiotomography. The LCA was surgically reimplanted into the aorta. After 3 years of postoperative follow-up, the patient developed an LCA aneurysm. Diagnosis of cardiac ischemia in childhood remains a challenge, and careful evaluation of coronary arteries on the echocardiogram is an important tool. In this report, we present a case of ALCAPA with an uncommon postoperative outcome. PMID:26770839

    Hurler-Scheie syndrome is caused by alpha-l-iduronidase deficiency. Enzyme replacement therapy (ERT) can improve physical capacity and reduces organomegaly. However, the effect on bradytrophic connective tissue is limited. As intravenously administered enzyme cannot cross the blood-brain barrier, the therapy of choice for the more severe Hurler syndrome is haematopoietic stem cell transplantation (HCT). In the more attenuated Scheie syndrome, neurological impairment is less severe; therefore, ERT may be appropriate to treat these patients. Information on long-term outcome in Scheie patients undergoing ERT is scarce. We report a 38-year-old female Scheie patient who has been on ERT for 8 years. While non-neurological symptoms improved, she developed paresthesias in her hands and feet and progressive pain in her legs. Somatosensory evoked potentials were abnormal, suggesting dysfunction of the dorsal funiculus and lemniscus medialis. After 6 years of ERT, a spinal MRI showed dural thickening at the upper cervical spine. These soft-tissue deposits are presumably due to the accumulation of mucopolysaccharides. Intramedullary hyperintensities at the level of C1/2 revealed cervical myelopathy. An MRI before the start of ERT had shown milder spinal lesions. Cystic lesions in the white matter of the centrum semiovale due to dilated Virchow-Robin spaces were essentially unchanged compared with the MRI scan before ERT. Decompression of the spinal cord resulted in clinical improvement. In an adult patient with Scheie syndrome, ERT failed to prevent progression of cervical myelopathy. Clinical significance of cerebral changes is unclear. Whether early HCT or intrathecal ERT could have prevented these lesions remains speculative. PMID:19894140

    Five patients had severe generalized disorder of memory, which lasted for several months after anterior communicating artery aneurysm surgery. Two of them had no signs of frontal lobe lesions. They were confused for not more than four days after surgery. One of them performed normally on the non-memory tests and short-term memory tests. Cues did not substantially improve his poor memory performance. The other patient had similar test results, but he had poor imagination in an inkblot perception test. Three patients had frontal lobe lesions. Two of them were restless, confused and confabulating, with one showing apathetic and stereotyped behaviour for more than a month after surgery. On the memory tests they showed disinhibition of irrelevant associations or deficient initiative. Cueing markedly improved their poor retrieval. These defects seem to be associated with frontal lobe lesions and can affect memory but are not obligatory features of amnesia. PMID:4053628

    Vascular improvements in the nonactive regions during exercise are likely primarily mediated by increased shear rate (SR). Individuals with spinal cord injury (SCI) experience sublesional vascular deconditioning and could potentially benefit from upper body exercise-induced increases in lower body SR. The present study utilized a single bout of incremental arm-crank exercise to generate exercise-induced SR changes in the superficial femoral artery in an effort to evaluate the acute postexercise impact on superficial femoral artery endothelial function via flow-mediated dilation (FMD), and determine regulatory factors in the nonactive legs of individuals with and without SCI. Eight individuals with SCI and eight age, sex, and waist-circumference-matched able-bodied (AB) controls participated. Nine minutes of incremental arm-crank exercise increased superficial femoral artery anterograde SR (P = 0.02 and P < 0.01), retrograde SR (P < 0.01 and P < 0.01), and oscillatory shear index (OSI) (P < 0.001 and P < 0.001) in both SCI and AB, respectively. However, these SR alterations resulted in acute postexercise increases in FMD in the AB group only (SCI 6.0 ± 1.2% to 6.3 ± 2.7%, P = 0.74; AB 7.5 ± 1.4% to 11.2 ± 1.4%, P = 0.03). While arm exercise has many cardiovascular benefits and results in changes in SR patterns in the nonactive legs, these changes are not sufficient to induce acute changes in FMD among individuals with SCI, and therefore are less likely to stimulate exercise training-associated improvements in nonactive limb endothelial function. Understanding the role of SR patterns on FMD brings us closer to designing effective strategies to combat impaired vascular function in both healthy and clinical populations. PMID:25847920

  10. Circulating oxidized low-density lipoproteins and arterial elasticity: comparison between men with metabolic syndrome and physically active counterparts

    PubMed Central

    2010-01-01

    Background Accumulation of oxidized low-density lipoproteins in the intimae of arteries and endothelial dysfunction are key events in the development of atherosclerosis. Patients with metabolic syndrome are at high risk for cardiovascular diseases but the linkage between metabolic syndrome and atherosclerosis is incompletely understood. We studied whether the levels of oxidized LDL and arterial elasticity differ between metabolic syndrome patients and physically active controls. Methods 40 men with metabolic syndrome and 40 physically active controls participated in this cross-sectional study. None of the study subjects had been diagnosed with cardiovascular disease. Levels of oxidized LDL were assessed by a two-site ELISA immunoassay. Arterial elasticity was assessed non-invasively by the HDI/PulseWave™ CR-2000 arterial tonometer. Results Levels of oxidized LDL were 89.6 ± 33.1 U/L for metabolic syndrome subjects and 68.5 ± 23.6 U/L for controls (p = 0.007). The difference remained significant after adjustment for LDL cholesterol. Large artery elasticity index (C1) was 16.2 ± 4.1 mL/mmHgx10 for metabolic syndrome subjects and 19.4 ± 3.7 mL/mmHgx10 for controls (p = 0.001), small artery indices (C2) were 7.0 ± 3.2 mL/mmHgx100 and 6.5 ± 2.9 mL/mmHgx100 (NS), respectively. Conclusions Subjects with metabolic syndrome had elevated levels of oxidized LDL and reduced large arterial elasticity compared to controls. This finding may partly explain the increased risk for cardiovascular diseases among metabolic syndrome patients. Trial registration ClinicalTrials.gov NCT01114763 PMID:20727144

    Phantom limb pain is a phenomenon in which patients experience pain in a part of the body that no longer exists. In several treatment modalities, spinal cord stimulation (SCS) has been introduced for the management of intractable post-amputation pain. A 46-year-old male patient complained of severe ankle and foot pain, following above-the-knee amputation surgery on the right side amputation surgery three years earlier. Despite undergoing treatment with multiple modalities for pain management involving numerous oral and intravenous medications, nerve blocks, and pulsed radiofrequency (RF) treatment, the effect duration was temporary and the decreases in the patient's pain score were not acceptable. Even the use of SCS did not provide completely satisfactory pain management. However, the trial lead positioning in the cauda equina was able to stimulate the site of the severe pain, and the patient's pain score was dramatically decreased. We report a case of successful pain management with spinal cauda equina stimulation following the failure of SCS in the treatment of intractable phantom limb pain. PMID:27103968

    Forty-seven year old female, with a history of anorexia nervosa, was admitted to a medical stabilization unit (ACUTE) complaining of abdominal pain exacerbated by oral intake, associated with nausea, and relieved by emesis. Admission body mass index was 10.6. Labs were notable for hepatitis and hypoglycemia. On her progressive oral refeeding plan, she suddenly developed severe abdominal pain. Computed tomography (CT) revealed gastric dilatation and superior mesenteric artery (SMA) syndrome. SMA syndrome is a rare complication of severe malnutrition resulting from compression of the duodenum between the aorta and the SMA. It is diagnosed by an upper gastrointestinal series or an abdominal CT. Gastric dilatation, in turn, is a rare complication of SMA syndrome to be included in the differential diagnoses of abdominal pain in severely malnourished patients as it is potentially life-threatening. The patient was switched to an oral liquid diet, began weight restoring, and had resolution of symptoms. PMID:25639251

    PurposeTo evaluate the safety and efficacy of transarterial embolization of life-threatening arterial rupture in patients with vascular Ehlers–Danlos syndrome (vEDS) in a single tertiary referral center.MethodsWe retrospectively analyzed transarterial embolization for vEDS performed at our institution from 2000 to 2012. The indication of embolization was spontaneous arterial rupture or pseudoaneurysm with acute bleeding. All interventions used a percutaneous approach through a 5F or less introducer sheath. Embolic agents were microcoils and glue in 3 procedures, glue alone in 2, and microcoils alone in 2.ResultsFive consecutive vEDS patients were treated by 7 embolization procedures (4 women, mean age 29.8 years). All procedures were successfully performed. Two patients required a second procedure for newly arterial lesions at a different site from the first procedure. Four of the five patients were still alive after a mean follow-up of 19.4 (range 1–74.7) months. One patient died of multiple organ failure 2 days after procedure. Minor procedural complications were observed in 3 procedures (43 %), all directly managed during the same session. Remote arterial lesions occurred after 3 procedures (43 %); one underwent a second embolization, and the other 2 were observed conservatively. Puncture site complication was observed in only one procedure (14 %).ConclusionEmbolization for vEDS is a safe and effective method to manage life-threatening arterial rupture.

    This study compared arterial stiffness and wave reflection at rest and following maximal exercise between individuals with and without Down syndrome (DS), and the influence of body mass index (BMI), peak oxygen uptake (VO2 peak) on changes in arterial stiffness. Twelve people with DS (26.6 ± 2.6 yr) and 15 healthy controls (26.2 ± 0.6 yr) completed this study. Intima-media thickness (IMT) and stiffness of common carotid artery was examined. Hemodynamic and arterial variables were measured before and 3-min after exercise. Persons with DS had higher BMI and lower VO 2 peak than controls. IMT did not differ between groups. At rest, carotid β stiffness was significantly higher in persons with DS (P<0.05) but there was no difference in between groups for any of the other arterial stiffness measures. After exercise, persons with DS exhibited attenuated arterial stiffness responses in AIx-75, carotid β stiffness and Ep in contrast with controls (significant group-by-time interactions). When controlling for BMI and VO 2 peak, the interactions disappeared. In both groups combined, BMI was correlated significantly with carotid Ep and β at rest. VO 2 peak correlated significantly with AIx-75 and its pre-post change (r=-0.45, P=0.029; r=0.47, P=0.033, respectively). The arterial stiffness responses to maximal exercise in persons with DS were blunted, potentially reflecting diminished vascular reserve. Obesity and particularly VO 2 peak influenced these findings. These results suggest impaired vascular function in people with DS. PMID:23883823

    Purpose: To evaluate the safety and efficacy of the Amplatzer vascular plug (AVP) for embolization of the splenic artery in patients with hepatic hypoperfusion after orthotopic liver transplantation (OLT). Materials and Methods: Thirteen patients (9 men and 4 women) with a mean age of 56 years (range 22-70) who developed splenic artery syndrome after OLT with decreased liver perfusion and clinically relevant impairment of liver function (increased transaminase or serum bilirubin levels, thrombocytopenia, and/or therapy-refractory ascites) were treated by embolization of the proximal third of the splenic artery using the AVP. The plugs ranged in diameter from 6 to 16 mm, and they were introduced through femoral (n = 9), axillary (n = 3), or brachial (n = 1) access using a 5F or 8F guiding catheter. Results: The plugs were successfully placed, and complete occlusion of the splenic artery was achieved in all patients. Placement of two plugs was necessary for complete occlusion in 3 of the 13 patients. Occlusion took on average 10 min (range 4-35). There was no nontarget embolization or plug migration into more distal segments of the splenic artery. All patients showed improved arterial perfusion, including the liver periphery, on postinterventional angiogram. After embolization, liver function parameters (transaminase and bilirubin levels) improved with normalization of concomitant thrombocytopenia and a decrease in ascites volume. Conclusion: Our initial experience in a small patient population with SAS suggests that the AVP enables precise embolization of the proximal splenic artery, thus providing safe and effective treatment for poor liver perfusion after OLT due to SAS.

    Horner syndrome, a triad of ptosis, anisocoria, and anhidrosis, results from interruption in the oculosympathetic pathway. It is classically described as either congenital or acquired to depict its underlying pathophysiology and requisite work-up. We report a case of a 10-month-old infant presenting with an acute onset of left Horner syndrome secondary to a spontaneous extracranial internal carotid artery dissection. To the best of our knowledge, this is the first case report in the literature of acute onset of acquired infantile Horner syndrome in association with spontaneous carotid artery dissection confirmed with magnetic resonance angiogram.

    Carpal tunnel syndrome is the most frequent neuropathy of the upper extremity, that mainly occurs in manual workers and individuals, whose wrist is overloaded by performing repetitive precise tasks. In the past it was common among of typists, seamstresses and mechanics, but nowadays it is often caused by long hours of computer keyboard use. The patient usually complains of pain, hypersensitivity and paresthesia of his hand and fingers in the median nerve distribution. The symptoms often increase at night. In further course of the disease atrophy of thenar muscles is observed. In the past the diagnosis was usually confirmed in nerve conduction studies. Nowadays a magnetic resonance scan or an ultrasound scan can be used to differentiate the cause of the symptoms. The carpal tunnel syndrome is usually caused by compression of the median nerve passing under the flexor retinaculum due to the presence of structures reducing carpal tunnel area, such as an effusion in the flexor tendons sheaths (due to overload or in the course of rheumatoid diseases), bony anomalies, muscle and tendon variants, ganglion cysts or tumors. In some cases diseases of upper extremity vessels including abnormalities of the persistent median artery may also result in carpal tunnel syndrome. We present a case of symptomatic carpal tunnel syndrome caused by thrombosis of the persistent median artery which was diagnosed in ultrasound examination. The ultrasound scan enabled for differential diagnosis and resulted in an immediate referral to clinician, who recommended instant commencement on anticoagulant treatment. The follow-up observation revealed nearly complete remission of clinical symptoms and partial recanalization of the persistent median artery. PMID:26676173

    Based on past laboratory and anecdotal clinical experience, we hypothesized that prolonged cervical spinal cord stimulation (SCS) in the acute settings of aneurysmal subarachnoid hemorrhage (aSAH) would be both safe and feasible, and that 2-week stimulation will reduce incidence of cerebral arterial vasospasm. The goal of our clinical study was to establish feasibility and safety of cervical SCS in a small group of selected aSAH patients. Single-arm non-randomized prospective study of cSCS in aSAH patients involved percutaneous implantation of 8-contact electrode in 12 consecutive aSAH patients that satisfied strict inclusion criteria. The electrode insertion was performed immediately upon surgical or endovascular securing of the ruptured aneurysm while the patient was still under general anesthesia. Patients were stimulated for 14 consecutive days or until discharge. There were no complications related to the electrode insertion or to SCS during the study and no long-term side effects of SCS during 1-year follow-up. There was 1 unrelated death and two electrode pullouts. This article summarizes technical details of SCS electrode insertion and the stimulation parameters used in the research study. Our study of SCS for prevention of vasospasm after aSAH conclusively shows both safety and feasibility of this promising treatment approach. Despite high level of acuity in aSAH patients, impaired level of consciousness, frequent patient re-positioning, need in multiple tests and variety of monitors, SCS electrodes may be safely implanted and maintained for the two-week period. Long-term follow up shows no adverse effects of cervical SCS in this patient category. PMID:24059581

    Superior mesenteric artery (SMA) syndrome is defined as a compression of the third portion of the duodenum by the abdominal aorta and the overlying SMA. SMA syndrome associated with anorexia nervosa has been recognized, mainly among young female patients. The excessive weight loss owing to the eating disorder sometimes results in a reduced aorto-mesenteric angle and causes duodenal obstruction. Conservative treatment, including psychiatric and nutritional management, is recommended as initial therapy. If conservative treatment fails, surgery is often required. Currently, traditional open bypass surgery has been replaced by laparoscopic duodenojejunostomy as a curative surgical approach. However, single incision laparoscopic approach is rarely performed. A 20-year-old female patient with a diagnosis of anorexia nervosa and SMA syndrome was prepared for surgery after failed conservative management. As the patient had body image concerns, a single incision laparoscopic duodenojejunostomy was performed to achieve minimal scarring. As a result, good perioperative outcomes and cosmetic results were achieved. We show the first case of a young patient with SMA syndrome who was successfully treated by single incision laparoscopic duodenojejunostomy. This minimal invasive surgery would be beneficial for other patients with SMA syndrome associated with anorexia nervosa, in terms of both surgical and cosmetic outcomes. PMID:26668518

    OBJECTIVES The management of arterial pathology in individuals with vascular Ehlers-Danlos syndrome (vEDS) remains a challenge. Here we describe the correlation between COL3A1 gene mutation type and the clinical phenotype in individuals with vEDS. METHODS Individuals with confirmed molecular diagnoses of vEDS were enrolled in a multi institutional natural history study. Data collected included demographics, clinical and family histories, arterial pathology (aneurysm, dissection, and rupture), operative details, and autopsy reports. Individuals were classified into two cohorts based on the type of COL3A1 mutations and their effect on the amount of normal collagen produced: MIN group had mutations that lead to minimal (10–15%) production of normal type III collagen and HI group had haploinsufficiency mutations that lead to production of half the normal type III collagen. RESULTS A cohort of 68 (72%) individuals from 56 families had arterial pathology (44% male, 13% HI). The HI group was older at the time of their first vascular event (mean 42 years, range 26–58 vs. 33 years, range 8–62, P = .016). The HI group had a higher incidence of aortic pathology compared to the MIN group (56% vs. 21%. P = .025). Visceral arterial pathology was seen in 43 arteries in 23 individuals in the MIN group versus only a single artery in 5 individuals in the HI group. Emergent surgical procedures were more likely to be undertaken when vEDS diagnosis was not known (81% vs. 41%, P = .005) and the majority of these procedures were open surgical repair compared to endovascular repair (81% vs. 19%, P = .019). In the elective setting, there was equal use of open and endovascular repair. Post-operative complications were highest when the diagnosis of vEDS was not known (62% vs. 14%, P < .001) and when procedures were undertaken in an emergency setting (5% vs. 55% P < .001). There was no mortality due to arterial complications in the HI cohort and 21% in the MIN cohort (P = .132

    Failure of spinal cord stimulation (SCS) may be due to hardware problems, migration of electrodes and, in the long-term, plasticity in the spinal cord with habituation to the stimulation current. We describe a series of seven patients who experienced acute therapeutic loss of SCS effects following an acute nociceptive event unrelated to primary pathology. There were no hardware problems. We called this 'Pseudofailure', as the effective stimulation returned in all patients following a period off stimulation or reprogramming. This phenomenon has not been reported previously in the literature. Over a 4-year period, we managed seven patients with this feature: four had received SCS for complex regional pain syndrome and three for failed back surgery syndrome. In all seven cases, there was cessation of the pain relief afforded by SCS following an acute painful event: four patients had trauma, two patients had domestic electric shock and one patient suffered shingles (varicella zoster infection). We excluded hardware-related problems in all cases. In two patients, SCS effects could be regained by an initial attempt at reprogramming. In the remaining five cases reprogramming was unsuccessful, and stimulation was switched off for several months before recommencing, when we discovered a return of good therapeutic effect. We conclude that SCS may seem to fail following a separate strong nociceptive stimulus. Stimulation may be regained with reprogramming or following a period with stimulation switched off. We would, therefore, advise against removal of SCS hardware in the first instance. PMID:27551417

    The Guyon's canal syndrome is a well known clinical entity and may have significant impact on patient's quality of life. We report a case of 43-year-old male who presented with complaints of pain and numbness in right hand and difficulty in writing for past one month. On imaging diagnosis of Guyon's canal syndrome because of tortuous ulnar artery was made with additional findings of DeQuervain's stenosing tenosynovitis and dorsal intercalated segmental instability syndrome with ligamentous injury and subsequently these were confirmed on surgery. Although it is a rare syndrome, early diagnosis and treatment prevents permanent neurological deficits and improve patient's quality of life. PMID:20076781

    After high cervical percutaneous cordotomy for pain in malignant disease, 12 patients died during sleep at postoperative intervals between 1 and 8 days. Nine died after a first cordotomy and three after a second (contralateral) procedure. All except one had known pulmonary disease before operation. The operated segment of the spinal cord (C2) was studied histologically after death. Superposition of lesion outlines made it possible to determine those parts of the lesioned areas common to all unilateral and bilateral cases respectively. All cases dying of presumed respiratory dysfunction syndrome had lesions involving the region of the anterolateral funiculus in the C2 segment containing "pain" fibres activated from the second to fifth thoracic dermatomes. The fibres whose destruction appeared to be responsible for respiratory dysfunction syndrome were completely intermingled with ascending "pain" fibres. The possibility of these fibres being afferent in function is discussed. Images PMID:1479392

    Significant left main coronary artery (LMCA) stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES), extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion). However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI) with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI). In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management. PMID:26557745

    This study reviews our experience with dynamic computed tomographic angiography (CTA) as an imaging modality in the evaluation of popliteal artery entrapment syndrome (PAES). Eight patients with surgically proven PAES were included in this study. Dynamic CTA studies performed with the feet in neutral and plantar flexed positions were reviewed for the detailed anatomy of the region and to define the location and extent of the stenosis, occlusions and collateral circulation. These findings were compared with intraoperative observations. CTA provided adequate angiographic and anatomic information required to arrive at the diagnosis and make a surgical decision. Thirteen limbs were affected in eight patients. There was popliteal artery occlusion in four limbs, stenosis at rest that was accentuated on stress imaging in two limbs, and patent popliteal artery with marked stenosis on stress imaging in seven limbs. Long-segment stenosis was seen in functional entrapment compared to short-segment stenosis in anatomic PAES. Anteroposterior compression of the popliteal artery in anatomic PAES unlike the side-to-side compression in functional PAES was a unique observation in this study. The CTA and surgical characterisation and classification of PAES matched in all the patients, except for misinterpretation of compressing fibrous bands as accessory slips of muscles in three limbs. In conclusion, dynamic CTA is a robust diagnostic tool that provides clinically relevant information and serves as a rapidly performed and easily available 'one-stop-shop' imaging modality in the management of PAES.

    Ehlers-Danlos syndrome (EDS) is a rare heterogeneous group of connective tissue disorders. The vascular type (vEDS) is an autosomal dominant disorder caused by heterozygous mutations in the COL3A1 gene predisposing to premature arterial, intestinal, or uterine rupture. We report a case of a 38-year-old woman with a recent diagnosis of vEDS admitted in the Emergency Department with a suspicion of a pyelonephritis that evolved to a cardiopulmonary arrest. A fatal retroperitoneal hematoma related with a haemorrhagic dissection of the right renal artery was found after emergency surgery. This case highlights the need to be aware of the particular characteristics of vEDS, such as a severe vascular complication that can lead to a fatal outcome. PMID:26175915

    Superior mesenteric artery syndrome (SMAS) is an uncommon cause of vomiting and weight loss due to compression of the third part of the duodenum by the superior mesenteric artery. Small bowel adenocarcinoma is an uncommon tumor, which is frequently delayed in diagnosis as its symptoms and signs are non-specific. The present study describes a case of SMAS occurring in a 51-year-old man, caused by intestinal obstruction secondary to a primary adenocarcinoma of the duodenal-jejunal junction. To the best of our knowledge, the present case is the first report of small bowel adenocarcinoma masquerading as SMAS. The present case highlights the importance of considering the possibility of SMAS in patients with upper bowel obstruction caused by intestinal carcinoma. PMID:26998097

    We describe a 26-year-old white female with a history of Raynaud phenomenon, erythema nodosum, polyarthralgias, migraine, vertigo, seizures, transient ischemic attacks, one fetal loss, and false positive VDRL, who developed milk hypertension without overt lupus nephritis. She had positive antinuclear antibodies (ANA) and double-stranded deoxyribonucleic acid (dsDNA) antibodies. The lupus anticoagulant test (LAC) and cardiolipins antibodies (aCL) were positive. She was diagnosed as having a Systemic Lupus Erythematosus-like illness (SLE-like) with 'secondary' antiphospholipid syndrome (APS). Renal spiral computed tomography (CT) with intravenous (IV) contrast showed bilateral renal artery stenosis. Anticoagulation with acenocumarol was started. She became normotensive without antihypertensive drugs five months later. A follow-up renal spiral CT showed complete recanalization of both renal arteries, making thrombosis the more likely culprit pathology in the stenosis. After two years follow up the patient is normotensive. She remains on acenocumarol. PMID:10713649

    Electrocardiographic characteristics of Wellens syndrome (WS) consist of deeply inverted T waves or biphasic T waves in anterior precordial leads. Studies have shown that patients with WS have critical stenosis or complete obstruction of the proximal left anterior descending coronary artery (LAD) and high risk for the development of extensive anterior myocardial infarction. Here, we reported a case presenting with WS and with a small plaque in the proximal LAD and slow flow in the LAD other than significant stenosis of the proximal LAD detected by coronary angiography.

    Twin reversed arterial perfusion (TRAP) syndrome is a rare condition (0.3:10,000 births) that occurs in monochorionic twin pregnancies, resulting in coexistence of a normal “pump” twin and an acardiac twin. The acardiac twin is dependent upon the normal twin to provide circulation by means of vascular anastomosis. Many of the bizarre defects are felt to be caused by low oxygen tension and this causes dramatic alteration in the twin fetal physiology and high prenatal mortality. The acardiac twin is a parasite, putting the pump fetus at risk of high output cardiac failure. Overall only 50% of pump twins survive. We present a case in a twenty year female, gravida two, para one, living one, full term normal pregnancy, ultrasound showed twin pregnancy. Following delivery, the first fetus survived only for one day and the second fetus showed features of TRAP syndrome. PMID:24596758

    Internal carotid artery dissection (ICAD) is a rare entity that either results from traumatic injury or can be spontaneously preceded or not by a minor trauma such as sporting activities. It represents a major cause of stroke in young patients. The diagnosis should be suspected with the combination of Horner's syndrome, headache or neck pain, and retinal or cerebral ischaemia. The confirmation is frequently made with a magnetic resonance angiography (MRA). Although anticoagulation with heparin followed by vitamin-K-antagonists is the most common treatment, there is no difference in efficacy of antiplatelet and anticoagulant drugs at preventing stroke and death in patients with symptomatic carotid dissection. We describe a patient with ICAD following deep sea scuba diving, who presented with Horner's syndrome and neck pain and was successfully treated with anticoagulants. PMID:27525139

    Cerebral hyperperfusion is a relatively rare syndrome with significant and potentially preventable clinical consequences. The pathophysiology of cerebral hyperperfusion syndrome (CHS) may involve dysregulation of the cerebral vascular system and hypertension, in the setting of increase in cerebral blood flow. The early recognition of CHS is important to prevent complications such as intracerebral hemorrhage. This review will focus on CHS following carotid endarterectomy and carotid artery stenting. We will discuss the typical clinical features of CHS, risk factors, pathophysiology, diagnostic modalities for detection, identification of patients at risk, and prevention and treatment. Although currently there are no specific guidelines for the management of CHS, identification of patients at risk for CHS and aggressive treatment of hypertension are recommended. PMID:27602202

    The aim of the study was to evaluate therapeutic effects of losartan on intravascular thrombocyte activity (ITA) in patients suffering from arterial hypertension with metabolic syndrome (MS). The subjects of the study were 35 patients administered losartan 50 mg a day for 4 months. The dynamics of the following parameters were evaluated: anthropometric parameters, blood lipids, lipid peroxidation in blood plasma and thrombocytes, the anti-oxidative protection of the liquid part of blood and platelets, and ITA. Student criterion was used for statistical analysis. In patients with AH and MS losartan had a positive effect on peroxidation syndrome and optimized ITA. To maintain the positive effects, prolonged administration of losartan is needed. In order to lower body mass in AH patients with MS losartan should be used in combination with non-drug means.

    Background Cardiac surgery induces many physiologic changes including major inflammatory and sympathetic nervous system responses. Here, we conducted a single-centre pilot study to generate hypotheses on the potential immune impact of adding high spinal anaesthesia to general anaesthesia during cardiac surgery in adults. We hypothesized that this strategy, previously shown to blunt the sympathetic response and improve pain management, could reduce the undesirable systemic inflammatory responses caused by cardiac surgery. Methods This prospective randomized unblinded pilot study was conducted on 14 patients undergoing cardiac surgery for coronary artery bypass grafting and/or aortic valve replacement secondary to severe aortic stenosis. The primary outcome measures examined longitudinally were serum pro-inflammatory (IL-6, IL-1b, CCL2), anti-inflammatory (IL-10, TNF-RII, IL-1Ra), acute phase protein (CRP, PTX3) and cardiovascular risk (sST2) biomarkers. Results The kinetics of pro- and anti-inflammatory biomarker was determined following surgery. All pro-inflammatory and acute phase reactant biomarker responses induced by surgical stress were indistinguishable in intensity and duration between control groups and those who also received high spinal anaesthesia. Conversely, IL-10 levels were markedly elevated in both intensity and duration in the group receiving high spinal anesthesia (p = 0.005). Conclusions This hypothesis generating pilot study suggests that high spinal anesthesia can alter the net inflammatory response that results from cardiac surgery. In appropriately selected populations, this may add incremental benefit by dampening the net systemic inflammatory response during the week following surgery. Larger population studies, powered to assess immune, physiologic and clinical outcomes in both acute and longer term settings, will be required to better assess potential benefits of incorporating high spinal anesthesia.

    The superior mesenteric artery syndrome--also known as Wilkie's syndrome or as arteriomesenteric obstruction of the duodenum--is a rare condition of upper intestinal obstruction in which the third part of the duodenum is compressed by the overlying, narrow-angled superior mesenteric artery against the posterior structures. It is characterized by early satiety, recurrent vomiting, abdominal distention, weight loss and postprandial distress. When nonsurgical management is not possible or the problem is refractory, surgical intervention is necessary. Usually a reconstruction of the intestinal passage is performed. We report the first case of successful transposition of the superior mesenteric artery into the infrarenal aorta in the therapy of Wilkie's syndrome. PMID:19066831

    Background and Objectives Obstructive sleep apnea syndrome (OSAS) is associated with increased arterial stiffness and cardiovascular complications. The objective of this study was to assess whether the color M-mode-derived propagation velocity of the descending thoracic aorta (aortic velocity propagation, AVP) was an echocardiographic marker for arterial stiffness in OSAS. Subjects and Methods The study population included 116 patients with OSAS and 90 age and gender-matched control subjects. The patients with OSAS were categorized according to their apnea hypopnea index (AHI) as follows: mild to moderate degree (AHI 5-30) and severe degree (AHI≥30). Aortofemoral pulse wave velocity (PWV), carotid intima-media thickness (CIMT), brachial artery flow-mediated dilatation (FMD), and AVP were measured to assess arterial stiffness. Results AVP and FMD were significantly decreased in patients with OSAS compared to controls (p<0.001). PWV and CIMT were increased in the OSAS group compared to controls (p<0.001). Moreover, AVP and FMD were significantly decreased in the severe OSAS group compared to the mild to moderate OSAS group (p<0.001). PWV and CIMT were significantly increased in the severe group compared to the mild to moderate group (p<0.001). AVP was significantly positively correlated with FMD (r=0.564, p<0.001). However, it was found to be significantly inversely related to PWV (r=-0.580, p<0.001) and CIMT (r=-0.251, p<0.001). Conclusion The measurement of AVP is a novel and practical echocardiographic method, which may be used to identify arterial stiffness in OSAS. PMID:26617653

    Pseudoaneurysm formation has been reported in degenerated coronary artery saphenous vein bypass grafts, as well as in native coronary arteries after interventional procedures or blunt trauma. In contrast, pseudoaneurysm formation arising from the anastomotic site of native coronary vessels soon after coronary artery bypass grafting is rare, and neither the clinical presentation of this phenomenon nor its treatment is well described. We present the case of a 63-year-old man, a recent coronary artery bypass grafting patient, who presented with acute coronary syndrome due to a large and expanding pseudoaneurysm of the saphenous vein-to-ramus intermedius artery graft anastomosis. After several attempts, we successfully treated the pseudoaneurysm by means of percutaneous coil embolization. To our knowledge, this is the first report of acute coronary syndrome secondary to a pseudoaneurysm at the coronary artery–saphenous vein graft anastomosis. In addition, this appears to be the first report of the percutaneous treatment of such a pseudoaneurysm by means of coil embolization. PMID:26175645

    Von Hippel-Lindau syndrome is a rare, genetically based, autosomal dominant disorder. Its course is accompanied by the development of multiple neoplasms with the following tumours diagnosed most commonly in the central nervous system haemangioblastoma, clear cell renal cell carcinoma, phaeochromocytomas, pancreatic islet tumours, and endolymphatic sac tumours. Additionally, renal and pancreatic cystadenomas and epididymal cystadenomas have been diagnosed in males and cystadenomas of the broad ligament of the uterus have been diagnosed in females.The following paper presents the diagnostic way in a boy with vision disorders as the first symptom. Hypertension retinopathy and extremely elevated blood pressure were observed during ophthalmologic consultation. Complications of arterial hypertension were confirmed by echocardiography, which diagnosed hypertension cardiomyopathy. Hypertension retinopathy was confirmed by optical coherence tomography. Examinations performed in the neurology, cardiology, and finally endocrinology indicated a bilateral phaeochromocytoma as the cause of arterial hypertension. Moreover, some genetic investigations showed a mutation in the VHL ex.1 p.Y112 C gene responsible for the hereditary form of phaeochromocytoma which confirmed von Hippel-Lindau syndrome. After surgical treatment of phaeochromocytoma the patient needed careful management according to the surveillance protocol for von Hippel-Lindau disease. PMID:26268347

    Treatment of subclavian artery stenosis by percutaneous balloon angioplasty and adjunctive stent placement was shown to be safe and efficacious, but it may be limited in tight stenoses and long occlusions. We describe the case of a patient who experienced progressive angina pectoris associated with signs of cerebrovertebral insufficiency 9 yr after bypass surgery, including left internal mammary artery (LIMA) grafting to the left anterior descending coronary artery. Angiography showed reversed flow through the LIMA graft into the subclavian artery and a 4-cm occlusion beginning at the origin of the left subclavian artery, representing a rare coronary-subclavian steal syndrome. After a conventional approach failed, recanalization was performed successfully using laser guide wire angioplasty with adjunctive stent placement in a combined radial and femoral approach.

    Spinal cord injury (SCI) can be complete or incomplete. The level of injury in SCI is defined as the most caudal segment with motor function rated at greater than or equal to 3/5, with pain and temperature preserved. The standard neurological classification of SCI provided by the American Spinal Injury Association (ASIA) assigns grades from ASIA A (complete SCI) through ASIA E (normal sensory/motor), with B, C, and D representing varying degrees of injury between these extremes. The most common causes of SCI include trauma (motor vehicle accidents, sports, violence, falls), degenerative spinal disease, vascular injury (anterior spinal artery syndrome, epidural hematoma), tumor, infection (epidural abscess), and demyelinating processes ().

    A 21-year-old man was admitted to our hospital because of leg edema. Because laboratory findings revealed massive proteinuria and hypoproteinemia, he was diagnosed as having nephritic syndrome caused by minimal change disease. He was given a continuous heparin infusion and intravenous steroid therapy, at a prednisolone dose of 1 mg/kg per day, and his condition gradually improved. Five months after discharge, the patient's proteinuria relapsed. He was readmitted to our hospital and we restarted anticoagulant treatment with intravenous heparin and 60 mg prednisolone. On the third hospital day, he complained of chest pain with sudden onset and dyspnea. He quickly developed shock and died. The findings of an autopsy confirmed the presence of diffuse fibrin thrombi in bilateral pulmonary arteries, and we diagnosed the cause of death as diffuse pulmonary artery thrombosis. A coagulation test for activated partial thromboplastin time (aPTT) had already shown that aPTT was prolonged before the initiation of treatment. There may have been a deficit of antithrombin III (ATIII) - a cofactor of heparin - because of the proteinuria; thus, the continuous heparin treatment might not have been effective for the prevention of thrombosis. Alternatives to heparin treatment that do not suppress AT III, such as nafamostat mesilate or argatroban, which do not require the presence of AT III for their anticoagulant action, should be considered in cases similar to the that in the patient reported here. In patients with nephrotic syndrome who exhibit altered coagulation test results, the choice of anticoagulation therapy for treatment of the hypercoagulabilty status associated with nephrotic syndrome should be carefully considered.

The diagnosis was primarily made by high-resolution duplex ultrasound that revealed a dissection flap (length: 15.5 mm; thickness: 0.4 mm) together with the partially thrombosed false lumen at the dorsal wall of the left popliteal artery (degree of local diameter reduction: 56%). Further work-up by means of contrast-enhanced MR-A and conventional DSA confirmed a moderate stenosis of the popliteal artery compatible with focal dissection and excluded other causes such as popliteal artery entrapment syndrome. Under full-dose intravenous anticoagulation with unfractionated heparin that was switched to oral anticoagulation with vitamin K antagonists (target INR: 2-3) and conservative management of the blue toe the patient made a gradual, but eventually complete clinical recovery over 8 weeks.

    Superior Mesenteric Artery (SMA) syndrome is one of the rare cause of proximal small bowel obstruction wherein, the third part of the duodenum is compressed between the SMA at its origin and abdominal aorta due to decreased angulations in these two vessels. This decreased angulation exerts a compression effect on third part of the duodenum, resulting in duodenal obstruction which may be complete or partial. There are number of causes which can lead to this entity and will be discussed briefly. Here we report imaging findings of such a rare cause of proximal small bowel obstruction in a young male patient who presented to the emergency surgical department with non specific symptoms of pain abdomen and abdominal fullness. Patient was evaluated under the standard protocol in management of abdominal pain. General physical examination, erect and supine radiograph were taken. On barium meal follow-through examination, there was paucity of contrast agent distal to the second part of duodenum with proximal dilation of stomach, first and second part of duodenum which raised us the possibility of SMA syndrome. Reconstructed CECT abdomen confirmed the decreased angulation between SMA and abdominal aorta and diagnosed it as SMA syndrome. Findings were correlated on duodenojejunostomy anastomotic surgical procedure. Diagnosing and reporting such a case of SMA syndrome is of utmost importance because the clinical presentation being non-specific pertaining to small bowel obstruction which may pose a diagnostic difficulty to the surgeon and with the further delay in diagnosis, patients may end up with chronic symptoms and complications of the disease, repeated hospital visits and electrolyte abnormalities.

    Rarity of Superior Mesenteric Artery Syndrome (SMAS) and necessity of invasive tests to verify the diagnosis leads to patients receiving symptom-oriented drugs for a long period without any definite diagnosis. Diagnostic tests such as barium series, abdominal CT scan, abdominal angiography or magnetic resonance arteriography are used in patients with suspected SMAS. In pediatric patients, a non-invasive SMAS diagnosis may be considered easily with abdominal ultrasound performed by experienced hands. Megabulbus is used as a radiological term; however, reviewing the literature an endoscopic definition for megabulbus was not found. We decided to mention severely dilated pyloric ring and bulb as megabulbus. Megabulbus might be an indicator for SMAS. This is the first case of SMAS in adult and pediatric age groups presenting with megabulbus. PMID:25835120

    Thromboembolic disease in newborn infants is a serious problem. The most important risk factors are iatrogenic factors, including indwelling umbilical catheters or central catheters. Other risk factors include asphyxia, dehydration, sepsis, cardiac disease, respiratory distress syndrome (RDS), disseminated intravascular coagulation, congenital thrombophilia (i.e., protein C or protein S deficiency), maternal diabetes mellitus, and passive transfer of maternal antiphospholipid antibodies. Neonates are more vulnerable to thrombosis than adults due to their reduced fibrinolytic capability. We describe a case of a 1-day-old female newborn with arterial thromboembolism in the lower leg without a central line catheter. The thromboembolismin in this case was associated with RDS. The infant underwent thrombolysis, anticoagulation therapy, and surgical thrombectomy. The leg of the infant was subsequently amputated below the knee. The case is described here with a brief review of relevant literatures. PMID:25996336

    A 70-year old man presented with retrosternal chest pain. His electrocardiogram showed nonspecific T wave changes. Cardiac-specific troponin I (cTnI) was elevated. His condition was managed as acute coronary syndrome, following which he had two minor episodes of hemoptysis. A CT pulmonary angiogram showed no evidence of pulmonary embolism, but a large mass lesion was seen in the mediastinum. Echocardiography and cardiac MRI demonstrated a large solid mass, arising from the right ventricular outflow tract and causing compression of the main pulmonary artery (MPA). The differential diagnosis included pericardial and myocardial tumors and clotted aneurysm of the MPA. At surgery, a clotted aneurysmal sac was identified originating from the MPA and the defect was healed. Aneurysms of the MPA are rare. They most commonly present with dyspnea and chest pain. Compression of surrounding structures produces protean manifestations. A high index of suspicion coupled with imaging modalities establishes the diagnosis. Blunt trauma to the chest, at the time of an accident 4 years previously, may explain this aneurysm. The patient's presentation with chest pain was probably due to compression and/or stretching of surrounding structures. Coronary artery compression simulating acute coronary syndrome has been documented in the literature. The rise in cTnI may have been due to right ventricular strain, as a result of right ventricular outflow obstruction by the aneurysm. This has not been reported previously in the literature. The saccular morphology and narrow neck of the aneurysm predisposed to stagnation leading to clotting of the lumen and healing of the tear, which caused the diagnostic difficulty.

    An association of pancreatic cancer and median arcuate ligament syndrome (MALS) is a rare and challenging situation in terms of treatment. A 60-year-old man diagnosed with pancreatic cancer underwent laparotomy. A pancreaticoduodenectomy was planned, but during the resection part of the operation, a celiac artery stenosis was noticed. The patient was diagnosed with MALS causing almost total celiac artery occlusion, with no radiological solution. The patient was re-operated the next day, and an iliac artery allograft was used for aorta-proper hepatic artery reconstruction, concomitant with the total pancreaticoduodenectomy. Preoperative meticulous evaluation of vascular structures of the celiac trunk and its branches is important, especially in pancreatic surgery. A vascular allograft may be a lifesaving alternative when vascular reconstruction is necessary. PMID:26715412

    Iatrogenic aortic injuries are rare and well-recognized complications of a variety of procedures, including spinal surgery. The placement of pedicle screws is sometimes associated with devastating consequences. Aortic perforation with rapid hematoma formation and delayed aortic trauma leading to pseudoaneurysm formation have been described in the literature. A case describing a significant time interval between iatrogenic aortic injury and diagnosis in the absence of pseudoaneurysm formation is described in this paper and, according to our knowledge, is unique in the literature. The aortic injury was successfully treated, selecting the appropriate graft and, as a consequence, normal spinal cord blood flow was achieved. PMID:26064771

    The metabolic syndrome (MetS) is highly prevalent in the North American population and is associated with increased risk for development of cerebrovascular disease. This study determined the structural and functional changes in the middle cerebral arteries (MCA) during the progression of MetS and the effects of chronic pharmacological interventions on mitigating vascular alterations in obese Zucker rats (OZR), a translationally relevant model of MetS. The reactivity and wall mechanics of ex vivo pressurized MCA from lean Zucker rats (LZR) and OZR were determined at 7-8, 12-13, and 16-17 wk of age under control conditions and following chronic treatment with pharmacological agents targeting specific systemic pathologies. With increasing age, control OZR demonstrated reduced nitric oxide bioavailability, impaired dilator (acetylcholine) reactivity, elevated myogenic properties, structural narrowing, and wall stiffening compared with LZR. Antihypertensive therapy (e.g., captopril or hydralazine) starting at 7-8 wk of age blunted the progression of arterial stiffening compared with OZR controls, while treatments that reduced inflammation and oxidative stress (e.g., atorvastatin, rosiglitazone, and captopril) improved NO bioavailability and vascular reactivity compared with OZR controls and had mixed effects on structural remodeling. These data identify specific functional and structural cerebral adaptations that limit cerebrovascular blood flow in MetS patients, contributing to increased risk of cognitive decline, cerebral hypoperfusion, and ischemic stroke; however, these pathological adaptations could potentially be blunted if treated early in the progression of MetS.

    Background: The prevalence of Metabolic syndrome (MetS) has been increased in Asian countries. It represents a cluster of cardiovascular risk factors including obesity, insulin resistance, lipid abnormality and hypertension. Objectives: The purpose of this study was to assess the association between MetS and outcome in patients undergoing coronary artery bypass grafting surgery (CABG). Patients and Methods: This prospective study was performed on patients scheduled for coronary artery bypass grafting surgery (CABG). All the patients were followed up in hospital and three months afterward. Patients were excluded if they were younger than 18 years or had severe comorbidities, a history of valvular heart disease, and low ejection fraction. Results: A total of 235 patients (135 women) with a mean age of 59 ± 9.3 years were included. MetS was more prevalent in women (P < 0.001). The most prevalent complications were bleeding [20 (8.5%)] and dysrhythmia [18 (7.7%)]. At three months follow-up, the frequency rates of readmission [24 (10.2%)] and mediastinitis [9 (3.8%)] were higher than other complications. Diabetes and MetS were risk factors for a long ICU stay (> 5 days) and atelectasia (P < 0.05). Significant associations were observed between diabetes and pulmonary embolism (P = 0.025) and mediastinitis (P = 0.051). Conclusions: Identification of MetS before CABG can predict the surgery outcome. Patients with MetS have increased risks for longer ICU stay and atelectasia. PMID:25478548

    Background Superior mesenteric artery syndrome (SMAS) results from the compression of the third part of the duodenum between the aorta and the proximal part of the superior mesenteric artery (SMA). Clinical presentation of SMAS is characterized by the dilatation of the proximal part of the third part of the duodenum. SMAS is a rare cause of the upper gastrointestinal system (UGS) obstruction. In this study, we aimed to present our clinical experience in the treatment of five patients with SMAS, which is a rare clinical condition requiring surgery. Patients and methods The retrospective study included five patients who were treated due to SMAS at our clinic between January 2010 and January 2014. Results All the patients were underweight, with a mean BMI of 15.73 (14-16). The clinical symptoms included epigastric pain after food intake, large volume bilious emesis, early satiety, failure to gain weight, indigestion, esophageal reflux, sense of fullness, and persistent weight loss. SMAS was diagnosed using barium meal studies, upper gastrointestinal endoscopy, abdominal ultrasonography, and CT angiography. Four patients underwent duodenojejunostomy and one patient was managed with gastrojejunostomy. No complication was observed during the postoperative period, and all the patients achieved significant improvement in symptoms. Conclusion SMAS is a rare cause of UGS obstruction, and the diagnosis of SMAS is often delayed. SMAS should be suspected in the differential diagnosis of the patients with unsubstantiated symptoms of persistent nausea, emesis, and significant weight loss. PMID:27385294

His urodynamic parameters were normal and lumbar magnetic resonance imaging (MRI) revealed a low-lying conus at the L2-3 level with a thickened fatty filum, and he was diagnosed as having tethered cord syndrome (TCS). The patient underwent a fully endoscopic detethering through an interlaminar approach with intraoperative neurophysiological monitoring. The thickened filum terminale was located and then the filum was coagulated and cut. The patient showed a significant improvement in his preoperative symptoms, and reported no problems at 2-year follow-up. Detethering of the spinal cord in tethered cord syndrome using a fully endoscopic interlaminar approach provides the advantages of minimal damage to tissues, less postoperative discomfort, early postoperative recovery, and a shorter hospitalization.

    Coronary artery ectasia (CAE) often represents a coronary angiography finding casually detected or following the occurrence of an acute coronary syndrome. The pathogenetic role of cocaine abuse in the genesis of CAE is still little known and very few data are available in literature. We describe a case of a 31-year-old male cocaine user admitted to our department for typical acute chest pain. Coronary angiography showed diffuse coronary ectasia with slow flows and without hemodynamically significant stenosis. An increasing of matrix metalloproteinases values and a reduction of their tissue inhibitors was showed both during hospitalization and at one month after discharge. This case report emphasizes the close relationship between cocaine abuse, CAE and acute coronary syndromes in patients without hemodynamically significant coronary stenosis. As reported by Satran et al, cocaine abuse should be considered an important risk factor for CAE and these patients appear to be at increased risk of angina and acute myocardial infarct. Further studies that can strengthen this hypothesis would be useful to deepen and better analyze this interesting association. PMID:27231522

    PubMed Central

    2013-01-01

    Background Infections are the leading cause of death in the acute phase following spinal cord injury and qualify as independent risk factor for poor neurological outcome (“disease modifying factor”). The enhanced susceptibility for infections is not stringently explained by the increased risk of aspiration in tetraplegic patients, neurogenic bladder dysfunction, or by high-dose methylprednisolone treatment. Experimental and clinical pilot data suggest that spinal cord injury disrupts the balanced interplay between the central nervous system and the immune system. The primary hypothesis is that the Spinal Cord Injury-induced Immune Depression Syndrome (SCI-IDS) is 'neurogenic’ including deactivation of adaptive and innate immunity with decreased HLA-DR expression on monocytes as a key surrogate parameter. Secondary hypotheses are that the Immune Depression Syndrome is i) injury level- and ii) severity-dependent, iii) triggers transient lymphopenia, and iv) causes qualitative functional leukocyte deficits, which may endure the post-acute phase after spinal cord injury. Methods/Design SCIentinel is a prospective, international, multicenter study aiming to recruit about 118 patients with acute spinal cord injury or control patients with acute vertebral fracture without neurological deficits scheduled for spinal surgery. The assessment points are: i) <31 hours, ii) 31–55 hours, iii) 7 days, iv) 14 days, and v) 10 weeks post-trauma. Assessment includes infections, concomitant injury, medication and neurological classification using American Spinal Injury Association impairment scale (AIS) and neurological level. Laboratory analyses comprise haematological profiling, immunophenotyping, including HLA-DR expression on monocytes, cytokines and gene expression of immune modulators. We provide an administrative interim analysis of the recruitment schedule of the trial. Discussion The objectives are to characterize the dysfunction of the innate and adaptive immune

    A 47-year-old woman was admitted to our hospital with a giant spinal arteriovenous malformation (AVM) causing heart failure and thoracic myelopathy. Angiography revealed that the spinal AVM had multiple feeding vessels branching from the 5th through 12th intercostal arteries. The drainage vein flowed to the azygos vein and superior vena cava. The AVM destroyed the 7th thoracic vertebra. The cardiac output was 16.7l/min and the shunt ratio was 64% before treatment. Embolization with cyanoacrylate was performed because the operation was considered to be associated with a significant risk of paraplegia and organ ischemia. The cardiac output decreased to 11.6l/min and the shunt ratio was reduced to 32%. After embolization the patient demonstrated no symptoms of either heart failure or sensory deficits. During embolization, provocative tests using sodium amytal and lidocaine with magnetic stimulation were also performed. The above findings suggest that provocative tests and magnetic stimulation are useful to predict paraplegia, which could result from embolization while, in addition, embolization is considered to be a useful treatment for multiple shunt and nidus in this region.

    Unlike vascular Ehlers-Danlos syndrome (EDS), classic EDS is rarely associated with vascular manifestation. We report the case of a 39-year-old man who presented with acute abdominal pain. At the time of presentation, the patient was in hypovolemic shock, and computed tomography angiogram demonstrated common iliac artery dissection with rupture. He underwent an attempted endovascular repair that was converted to an open repair of a ruptured right common iliac artery dissection. Subsequent genetic testing revealed a substitution of arginine for cysteine in type I collagen, COL1A1 exon 14 c.934C>T mutation, consistent with a rare variant of classic EDS. PMID:25597651

    May-Thurner syndrome is known as compression of the left common iliac vein by the right common iliac artery. We describe a case of an atypical compression of the inferior vena cava by the right common iliac artery secondary to a high aortic bifurcation. Despite an extensive collateral network, there was a significant venous gradient between the iliac veins and the inferior vena cava above the compression. After stenting the venous pressure gradient disappeared. Follow-up 4 months later revealed a good clinical response with a patent stent.

    Acute spinal cord infarction (ASCI) occurs infrequently and may have diverse causes. The diagnosis of ASCI, and particularly of an anterior spinal artery syndrome (ASAS) can be confirmed nowadays by MRI, whereas in the past only necropsy confirmation was possible. Pathophysiology and long-term prognosis may be better known at present and treatments more consistent. We present the longitudinal study and clinical features of 8 patients suffering from ASCI. All of them were personally studied and had MRI examinations, often with sequential studies. three groups must be considered: one included 4 cases of ASAS at cervical level, the second 2 cases of ASAS at thoracic level and the third group with infarction of the conus medullaris (ICM), one of them developed during surgical repair of an infrarenal aortic aneurysm. Motor and sensory sequelae were assessed in each case together with possible etiological factors. In conclusion, recovery after ASAS tends to be dependent on the severity of the initial deficit. At cervical level, clinical and morphological findings argue in favour of an extrinsic selective compression of the C7 right radiculo-medullary artery as responsible for the ASA. At thoracic level, the artery preferentially occluded seems to be the sulco-commisural artery as a consequence of disc compression. Finally, an underlying peculiarity of the pattern of arterial supply is a probable predisposing factor for ICM. Generally, the long-term prognosis of ASCI is not necessarily bad. PMID:7801036

    A 13-year-old boy with meningiomatosis, McCune-Albright syndrome, and gray platelet syndrome presented with an enlarging "lump" on his right forehead. A head CT scan revealed a polyostotic fibrous dysplasia involving the entire skull. A 3.4-cm right frontal osseous cavity and an overlying right forehead subcutaneous soft-tissue mass were seen, measuring 5.2 cm in diameter and 1.6 cm thick. Ultrasound of the cavity and overlying mass showed swirling of blood and an arterialized waveform. MRI revealed an en plaque meningioma underlying the cavity. An intraosseous pseudoaneurysm fed by 3 distal anterior division branches of the right middle meningeal artery (MMA) with contrast extravasation was found on angiography. Two MMA feeders were embolized with Onyx, with anterograde filling of the intraosseous cavity with Onyx. A small pocket of residual intracavity contrast filling postembolization from a smaller third MMA feeder eventually thrombosed and the forehead lump regressed. PMID:26588455

    Our objective was to characterize our experience with 8 patients with Rett syndrome undergoing scoliosis surgery in regard to rates of respiratory failure and rates of ventilator-acquired pneumonia in comparison to patients with neurologic scoliosis and adolescent idiopathic scoliosis. This study was a retrospective chart review of patients undergoing scoliosis surgery at a tertiary children's hospital. Patients were divided into 3 groups: (1) adolescent idiopathic scoliosis, (2) neurologic scoliosis, and (3) Rett syndrome. There were 133 patients with adolescent idiopathic scoliosis, 48 patients with neurologic scoliosis, and 8 patients with Rett syndrome. We found that patients with Rett syndrome undergoing scoliosis surgery have higher rates of respiratory failure and longer ventilation times in the postoperative period when compared with both adolescent idiopathic scoliosis and neurologic scoliosis patients. There is insufficient evidence to suggest a difference in the incidence of ventilator-acquired pneumonia between the Rett syndrome and the neurologic scoliosis group. We believe our findings are the first in the literature to show a statistically significant difference between these 3 groups in regard to incidence of respiratory failure. PMID:25991642

    Pulmonary vascular remodelling, mainly characterized by arterial medial thickening, is an important pathological feature of broiler ascites syndrome (AS). Since vascular smooth muscle cells (VSMC) form the major cellular component of arterial medial layer, we speculate that VSMC proliferation is one of the causes of pulmonary arterial medial thickening in ascitic broilers. Hence, the present study was designed to investigate the role of VSMC proliferation in pulmonary vascular remodelling in development of AS induced by low ambient temperature. Broilers in control group (22 +/- 1.5 degrees C) and low temperature group (11 +/- 2 degrees C) were sampled every week at 15-50 days of age. Proliferative indexes of VSMC in pulmonary arteries were assessed with proliferating cell nuclear antigen, and the relative medial thickness (RMT) and relative wall area (RWA), as indexes of pulmonary vascular remodelling, were examined by computer-image analysing system. The results showed that the high incidence (18.75%) of AS was induced by low temperature, and a significantly increased VSMC proliferation was observed in pulmonary arteries in the low temperature group at 22-50 days of age (P < 0.05). In addition, RMT and RWA in pulmonary arteries were significantly elevated in the low temperature group from 36 days of age (P < 0.05), indicating that pulmonary vascular remodelling occurred following VSMC proliferation in AS. Our data suggest that proliferation of VSMC may facilitate pulmonary vascular remodelling and have a pivotal role in AS induced by low ambient temperature. PMID:18045340

    Fat embolism syndrome (FES) is a rare and potentially fatal complication occurring most often after long bone or pelvic fractures and orthopaedic procedures. It can consist of pulmonary, central nervous system and cutaneous manifestations. The exact pathophysiology of emboli reaching the arterial circulation is poorly understood.1 It is suggested that this may occur by either 'paradoxical' embolism or microembolism.2 3 Its true incidence is unknown but increases in the presence of multiple closed fractures. It can be a diagnostic dilemma for clinicians and if suspected diffusion-weighted MRI is the modality of choice for the investigation of the central nervous system.4 We present the case of a 22-year-old man who developed multifocal cerebral infarcts, a right-sided cerebellar infarct and an infarct in the anterior cord bilaterally at the level of C5-C6 as a result of FES.

Methods Homocysteine concentrations were measured in 30 XFS/XFG patients and 18 age matched controls. In 21 patients and 17 controls the end diastolic diameter of the CCA and pulsatile distension were measured and BRS was calculated. Results There was no significant difference between the groups in sex distribution, age, heart rate, blood pressure, systemic diseases, or medication. In XFS/XFG patients homocysteine concentration was significantly elevated (unpaired t test, p = 0.023), and CCA stiffness was higher (p<0.05), while strain, cross sectional compliance coefficient, distensibility, and BRS were significantly reduced compared to the controls (Mann‐Whitney U test, p⩽0.013 for each parameter). In XFS/XFG patients a positive correlation was found between age and plasma homocysteine level (Pearson's correlation, r = 0.490, p = 0.007), and a negative correlation between age and BRS (Kendall's correlation r = −0.374, p = 0.021), as well as between homocysteine concentration and BRS (Kendall's correlation r = −0.377, p = 0.024). No correlation was seen between these variables in the control group. Conclusions These results suggest a pathological large artery function as well as altered parasympathetic vascular control in XFS/XFG which increases with age and with higher homocysteine concentration.

    Marfan syndrome (MFS) is a connective tissue disorder that is often associated with the fibrillin-1 (Fbn1) gene mutation and characterized by cardiovascular alterations, predominantly ascending aortic aneurysms. Although neurovascular complications are uncommon in MFS, the improvement in Marfan patients' life expectancy is revealing other secondary alterations, potentially including neurovascular disorders. However, little is known about small-vessel pathophysiology in MFS. MFS is associated with hyperactivated transforming growth factor (TGF)-β signaling, which among numerous other downstream effectors, induces the NADPH oxidase 4 (Nox4) isoform of NADPH oxidase, a strong enzymatic source of H2O2 We hypothesized that MFS induces middle cerebral artery (MCA) alterations and that Nox4 contributes to them. MCA properties from 3-, 6-, or 9-mo-old Marfan (Fbn1(C1039G/+)) mice were compared with those from age/sex-matched wild-type littermates. At 6 mo, Marfan compared with wild-type mice developed higher MCA wall/lumen (wild-type: 0.081 ± 0.004; Marfan: 0.093 ± 0.002; 60 mmHg; P < 0.05), coupled with increased reactive oxygen species production, TGF-β, and Nox4 expression. However, wall stiffness and myogenic autoregulation did not change. To investigate the influence of Nox4 on cerebrovascular properties, we generated Marfan mice with Nox4 deficiency (Nox4(-/-)). Strikingly, Nox4 deletion in Marfan mice aggravated MCA wall thickening (cross-sectional area; Marfan: 6,660 ± 363 μm(2); Marfan Nox4(-/-): 8,795 ± 824 μm(2); 60 mmHg; P < 0.05), accompanied by decreased TGF-β expression and increased collagen deposition and Nox1 expression. These findings provide the first evidence that Nox4 mitigates cerebral artery structural changes in a murine model of MFS. PMID:26945079

    Background: Sleep apnea is accompanied by some cardiovascular complications. It has even been hypothesized that sleep apnea, itself, can induce some of these complications. Given such controversies, we assessed the left ventricular mass index (LVMI) and systolic pulmonary artery pressure in patients with sleep apnea. Methods: Through convenience sampling, 56 patients with the obstructive sleep apnea syndrome (OSAS) were included in the present descriptive cross-sectional study. Patients with any past history of hypertension and diabetes mellitus were excluded. The apnea severity was assessed via the polysomnography-derived apnea-hypopnea index (AHI). All the patients underwent transthoracic echocardiography. In this cross-sectional study - data regarding age, gender, smoking, systolic and diastolic blood pressures, polysomnographic parameters (AHI, severity of disease, mean heart rate, mean oxygen saturation [SaO2], lowest SaO2, and duration of SaO2 below 90% [d.SaO2 < 90%]), and echocardiographic parameters (systolic pulmonary artery pressure and LVMI) were accumulated and processed. Results: Fifty-two men and 14 women at a mean age of 49.29 ± 11.79 years participated in this study. Systolic and was significantly high in the severe group compared with the mild group (128.21 ± 9.73 mmHg vs. 119.23 ± 12.5 mmHg; p value = 0.007). The LVMI was increased parallel to an increase in the severity of the OSAS, but that increase was not statistically significant (p value = 0.161). The d.SaO2 < 90% was positively correlated with the LVMI, and this relationship remained true after adjustment for the body mass index (r = 0.27; p value = 0.042). Conclusion: Severe OSAS was accompanied by a higher blood pressure. The LVMI did not differ significantly between the patients with the OSAS and those who did not suffer from other risk factors of cardiac diseases. PMID:27403184

    We report a case of Bland-White-Garland syndrome with advanced age. The patient, a 67-year-old women, presented with a history of congestive heart failure. Coronary catheterization revealed an anomalous origin of the left coronary artery (LCA) from the trunk of the pulmonary artery and huge right coronary aneurysm. Myocardial single photon emission computed tomography (SPECT) showed previous myocardial infarction with reversible ischemia in left anterior descending (LAD) region. We performed LCA direct closure and coronary artery bypass graft. The patient recovered uneventfully without signs of ischemia. Although a bypass graft was patent, left ventricular function had not been improved immediately probably due to the coronary flow pattern changes. PMID:21174671

    Popliteal artery entrapment syndrome (PAES) is a rare but important cause of leg ischemia and even disability in young athletes. Entrapment occurs because of an abnormal relationship between the popliteal artery and the surrounding muscular structures in the popliteal fossa. These anomalies lead to decreased blood flow to the affected leg with signs of claudication, coldness, and symptoms of exercise-induced leg pain. In this article, we present a case of a young soldier who presented with the above signs and symptoms in his left foot after exercise. On questioning, he admitted to having chronic lower leg pain. He was diagnosed with PAES in both legs and he was emergently treated with an arterial bypass procedure in the left one. He had no postoperative complications. PAES should be considered in the differential diagnosis of chronic or acute lower leg pain in any young patient. Early diagnosis and treatment can prevent limb loss and lead to a good operative outcome. PMID:24402998

  1. A patient with non-ST-segment elevation acute coronary syndrome: Is it possible to predict the culprit coronary artery?

    In acute coronary syndromes without ST-segment elevation (NSTE-ACS), identification of the culprit artery is, most often, not possible. In this case report, we elaborate on the likelihood of different culprit arteries in a patient with NSTE-ACS. While her symptoms were progressing, typical ECG findings of ischemia in the left coronary territories were diminishing. Instead, dynamic T-wave changes in the inferior leads were present and were most likely postischemic and "reischemic." Although the culprit artery could not be identified with certainty by means of these subtle changes, they correlated well with the findings on angiography and the ECG recorded afterward. This case report demonstrates the importance of analyzing ECG and its temporal changes in conjunction with evolving symptoms. PMID:27212142

    Acute infantile spinal muscular atrophy (SMA type I, Werdnig-Hoffmann disease) has generally been accepted as an autosomal recessive disorder. However, several investigators have noted a slightly increased male to female ratio. We describe here a family with two affected male sibs who had a form of acute infantile SMA with congenital bone fractures, whose parents were first cousins. Pedigree analysis strongly suggested autosomal recessive inheritance, but X linked recessive inheritance could not be ruled out. In view of the heterogeneity of the SMAs, and the distinct clinical features found in our patients, we suggest that their infantile SMA might well be a distinct entity. We suggest that SMA I with congenital contractures and bone fractures appears to be a recognisable disorder that can be distinguished from the more common classic form of SMA I. PMID:1865475

    The purpose of this study was to describe covered-stent treatment of a ruptured dissection of the superior mesenteric artery (SMA) in a patient with Ehlers‒Danlos syndrome. The patient was a 13-year-old girl initially presenting with abdominal pain. Dissection and rupture of the SMA were diagnosed on detailed examination. Conservative treatment was performed initially because open surgery was considered high risk. However, the abdominal pain recurred, and we decided to perform endovascular therapy. A coronary artery covered stent was placed in the true lumen to close the entry site of the dissection. The false lumen was obliterated using a post-dilation technique, completing treatment of the rupture. The patient recovered uneventfully after surgery. Classic-type Ehlers‒Danlos syndrome was diagnosed on the basis of physical findings and genetic analysis. The stent has remained adequately patent as of 2 years after surgery. This case report shows that dissection and rupture of the SMA can be treated successfully using a covered coronary artery stent in a patient with Ehlers‒Danlos syndrome. PMID:23891251

    The metabolic syndrome is associated with elevated peripheral vascular disease risk, characterized by mismatched blood flow delivery/distribution and local metabolism. The obese Zucker rat (OZR) model of the metabolic syndrome exhibits myriad vascular impairments, although their integrated impact on functional hyperemia remains unclear. In this study, arterial pressor responses and skeletal muscle perfusion were assessed in lean Zucker rats (LZR) and OZR during adrenergic stimulation (phenylephrine), challenge with thromboxane (U46619) and endothelium-dependent dilation (methacholine). OZR were hypertensive versus LZR, but this was abolished by adrenoreceptor blockade (phentolamine); pressor responses to U46619 were similar between strains and were abolished by blockade with the PGH2/TxA2 receptor antagonist, SQ-29548. Depressor reactivity to methacholine was impaired in OZR, but was improved by antioxidant treatment (TEMPOL). Across levels of metabolic demand, blood flow to in situ gastrocnemius muscle was restrained by adrenergic constriction in OZR, although this diminished with increased demand. O2 extraction, reduced in OZR vs. LZR across levels of metabolic demand, was improved by TEMPOL or SQ-29548; treatment with phentolamine did not impact extraction and neither TEMPOL nor SQ-29548 improved muscle blood flow in OZR. While VO2 and muscle performance were consistently reduced in OZR vs. LZR, treatment with all three agents improved outcomes, while treatment with individual agents was less effective. These results suggest that contributions of vascular dysfunction to perfusion, VO2 and muscle performance are spatially distinct, with adrenergic constriction impacting proximal resistance and endothelial dysfunction impacting distal microvessel-tissue exchange. Further, these data suggest that increasing skeletal muscle blood flow in OZR is not sufficient to improve performance, unless distal perfusion inhomogeneities are rectified. PMID:21123363

    1. Objective Combine collective clinical experience using oral propranolol therapy in PHACE syndrome infants with cerebrovascular anomalies. 2. Design Retrospective study of patients evaluated between July 2008 and October 2011. 3. Setting Seven pediatric dermatology centers. 4. Patients 32 infants with definite PHACE syndrome and cervical and/or intracranial arterial anomalies. 5. Intervention Oral propranolol: average dose of 1.8 mg/kg/day divided t.i.d. or b.i.d., for an average duration of 12.3 months. 6. Main Outcome Measure Adverse neurologic events. 7. Results 7/32 (22%) patients were categorized as higher-risk for stroke, defined on MRA as severe, long-segment narrowing or non-visualization of major cerebral or cervical vessels without anatomic evidence for collateral circulation, often in the presence of concomitant cardiovascular comorbidities. Only 1 patient developed a change in neurologic status during propranolol treatment: a mild right hemiparesis that remained static and improved while propranolol was continued. An additional 3 patients had worsening hemangioma ulceration and/or tissue necrosis during therapy. 8. Conclusions This is the largest report thus far of PHACE patients treated with propranolol. While no catastrophic neurologic events occurred, serious complications, particularly severe ulcerations were seen in a minority of patients, and given the sample size we cannot negate the possibility that propranolol could augment the risk of stroke in this population. We continue to advise caution in using systemic beta-blockers, particularly for children with vascular anomalies at higher risk for stroke. Use of the lowest possible dosage, slow dosage titration, and t.i.d. dosing in order to minimize abrupt changes in blood pressure and close follow-up, including neurologic consultation as needed, are recommended.

    Patient: Male, 41 Final Diagnosis: Sick Sinus Syndrome and absent left main coronary artery • separate ostia of left anterior descending and circumflex arteries in Holt-Oram Syndrome Symptoms: Conduction disturbance • seizure-like activity • upper extremity malformations Medication: — Clinical Procedure: Electro physiology study • coronary catheterization • pacemaker Specialty: Cardiology Objective: Congenital defects/diseases Background: Holt-Oram syndrome (HOS) is a rare but significant syndrome consisting of structural heart defects, conduction abnormalities, and upper extremity anomalies. It was first described in the British Heart Journal in 1960 by Mary Holt and Samuel Oram as a report of atrial septal defect, conduction disturbances, and hand malformations occurring in family members. Patients can present with heart blocks or symptoms of underlying congenital heart defects. Case Report: A 41-year-old man with Holt-Oram syndrome presented with seizure-like activity and was found to have an underlying conduction disturbance. Physical exam showed bilateral atrophic upper extremities with anatomic disfiguration, and weakness of the intrinsic hand muscles. Cardiovascular exam revealed a slow heart rate with irregular rhythm. EKG showed sinus arrest with junctional escape rhythm. Cardiac catheterization revealed coronary anomalies, including absent left main coronary artery and separate ostia of the left anterior ascending and left circumflex coronary artery. Coronary arteries were patent. Following electrophysiology study, sick sinus syndrome and AV block were diagnosed, and the patient received implantation of a permanent pacemaker. Conclusions: This patient presented with a seizure-like episode attributed to hypoxia during asystole from an underlying cardiac conduction defect associated with Holt-Oram syndrome. Arrhythmias and heart blocks are seen in these patients, and conduction defects are highly associated with congenital heart defects. Holt

    Hyperperfusion syndrome (HPS) after carotid artery stenting (CAS) may cause hemorrhagic or ischemic events leading to serious sequelae. We previously reported the staged angioplasty (SAP) to prevent HPS. In the present study, we analyzed our treatment results of SAP to know its effectiveness and problems. The study included 43 patients scheduled for SAP in whom preoperative single photon emission computed tomography (SPECT) showed severely impaired cerebral blood flow (CBF). The analyzed subjects were 38 males and 4 females, mean age was 73 ± 8.5 years old. SAP was indicated for the patients whose CBF ratio in the affected/unaffected hemisphere (asymmetry index) was below 0.8, and cerebrovascular reactivity measured by acetazolamide challenge was below 10%. First, percutaneous transluminal angioplasty (PTA) was performed. If PTA was successful, CAS was performed 2 weeks later. If PTA was not successful due to inadequate dilatation or extensive dissection, a stent was placed. SPECT was performed immediately after PTA and CAS to confirm the presence or absence of hyperperfusion phenomenon (HPP) indicating radiologic hyperperfusion. In 39 of 43 patients (91%), SAP was successfully performed and HPP was not observed. On the other hand, in the other four patients (9%), immediate stent placement was added due to inadequate dilatations in three patients and vascular dissection in one. Among 43 candidates for SAP, 41 patients (95.4%) had favorable course, but one hemorrhagic and one ischemic complications were observed after PTA. SAP was a relatively simple procedure, and its clinical results seemed acceptable. PMID:26447098

    Pulmonary arterial hypertension (PAH) is an uncommon but serious disease characterized by severe pulmonary vascular disease and significant morbidity and mortality. PAH associated with congenital heart disease (APAH-CHD) is one etiology of PAH that has innate characteristics delineating it from other forms of PAH. The patient with APAH-CHD presents with unique challenges consisting of not only pulmonary vascular disease but also the complexity of the cardiac lesion. Eisenmenger syndrome (ES) represents the severe end of the spectrum for disease in APAH-CHD. Over time, systemic-to-pulmonary shunting through cardiac defects increases pulmonary vascular resistance to levels significant enough to reverse shunting across the defect. Historically, ES patients have been reported to have better outcomes than IPAH despite similarities in pulmonary vascular disease. However, recent studies are challenging this notion. Nonetheless, APAH-CHD survival has improved with the advent of modern PAH targeted therapies. New therapeutic options have allowed us to reconsider the dogma of inoperability in APAH-CHD patients with unrepaired defects. Certainly advances have been made, however, investigators must continue to advance the field through controlled clinical trials in both adult and pediatric APAH-CHD patients. PMID:25604592

    Streptococcal toxic shock syndrome (STSS), an invasive Streptococcus pyogenes (Group A streptococcus) infection with hypotension and multiple organ failure, is quite rare in pregnancy but is characterized by rapid disease progression and high fatality rates. We present a case of STSS with infection-induced cardiac dysfunction in a pregnant woman who was treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO). A 24-year-old multiparous woman in the third trimester had early symptoms of high fever and diarrhea 1 day prior to admission to the hospital emergency department. On admission, she had multiple organ failure including circulatory failure. Due to fetal distress, emergency Cesarean section was carried out and transferred to intensive care units. She had refractory circulatory failure with depressed myocardial contractility with progressive multiple organ failure, despite receiving significant hemodynamic supports including high-dose catecholamine. Thus, VA-ECMO was initiated 18 h after intensive care unit admission. Consequently, ECMO provided extra time to recover from infection and myocardial depression. She was successfully weaned from VA-ECMO on day 7 and was discharged home on day 53. VA-ECMO can be a therapeutic option for refractory circulatory failure with significant myocardial depression in STSS. PMID:26758056

    PubMed

    2012-03-01

    Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences

    Scimitar syndrome is a rare congenital disorder. It is characterized by partial or total abnormal venous drainage of the right lung into the inferior vena cava, which is often associated with anomalous systemic arterial supply to the right lung, congenital cardiac anomalies, hypoplasia of the right lung and bronchial anomalies. Symptoms depend on the degree of the shunt and severity of the associated anomalies, which determine the treatment. We present a 6-year-old boy who was diagnosed as having the adult form of scimitar syndrome during evaluation for recurrent pulmonary infections, and underwent embolization with a detachable silicon balloon of the anomalous systemic arterial supply from the abdominal aorta to the right lower lung lobe. Successful elective surgery was performed 6 months later, in which right pulmonary veins were directed to the left atrium using a Gore-Tex patch by creating an intra-atrial tunnel. The patient has been symptom-free period during 6 months of follow-up, which supports the idea that recurrent pulmonary infections can be eliminated by embolization of the anomalous arterial supply.

    Thirty patients suffering from painful syndromes of the spine were admitted to a randomized controlled clinical trial. They were divided into two groups and treated either with transcutaneous electrical nerve stimulation (TENS), one application every other day, for 20 days or with TENS and an ointment containing etofenamate 10% gel, 3-5 cm daily on the day of TENS therapy, and the same dose twice daily on the other days. The associated therapy achieved, when compared with TENS alone, a statistically significant better outcome. Furthermore a marked improvement of symptoms was observed in a shorter period of time. Therapy was well tolerated and in only four cases mild, self-limiting, skin reactions were observed. On the basis of these results the use of etofenamate and TENS could represent a viable alternative to systemic nonsteroidal antiinflammatory drug therapy. PMID:2972631

    Hardikar syndrome is a multiple congenital anomaly syndrome first characterized in 1992 by Hardikar et al. to describe two individuals with cholestasis, cleft lip/palate, retinal pigmentation, intestinal abnormalities, and genitourinary anomalies. Between 1992 and 2002, four individuals with Hardikar syndrome were reported in the literature. The fourth individual [Maluf et al. (2002), Transplantation 74:1058-1061; Poley and Proud (2008) Am J Med Genet Part A 146A:2473-2479], who had progressive cholestatic liver disease ultimately requiring liver transplantation, has continued to be followed at our institution. Recently, at the age of 14 years, during an evaluation for refractory hypertension, she was found to have developed coarctation of the aorta that was treated with aortic angioplasty and stenting, dramatically improving her hypertension. Further vascular investigation also revealed a small aneurysm of her carotid artery requiring neurosurgical evaluation and anticoagulant therapy. To our knowledge, these vascular anomalies have not been reported in Hardikar syndrome and the high association of congenital heart disease in the individuals with Hardikar syndrome has not been further addressed. Herein, we discuss this additional clinical information, speculate briefly on possible molecular etiologies, and discuss potential cardiac surveillance recommendations. We hope that broadening the known phenotype of this very rare disorder will further aid clinicians in their management and surveillance for these individuals. PMID:26471230

    Background Superior mesenteric artery (SMA) syndrome is an uncommon condition resulting in partial small bowel obstruction because of external compression of the third portion of the duodenum between the SMA anteriorly and the aorta posteriorly. SMA syndrome often presents with postprandial nausea, bilious vomiting, and abdominal pain with associated weight loss. Onset of symptoms can be acute (occurring in the setting of rapid weight loss because of trauma/surgery) or can be vague and chronic over many years. Case Reports We present two cases of female adolescents who presented with symptoms of duodenal obstruction attributed to SMA syndrome. Both failed conservative treatment with weight gain and underwent successful laparoscopic duodenojejunostomy procedures with resolution of duodenal obstruction. Conclusion In the differential diagnosis of persistent nausea and bilious vomiting, even in the setting of an eating disorder, SMA syndrome should be considered. Upper gastrointestinal examination is the primary modality for diagnosing SMA syndrome, but ultrasound is an inexpensive, rapid screening tool for patients with unexplained abdominal pain. Abdominal computed tomography may also be helpful in selected patients. Conservative therapy consisting of nutritional support to enhance weight gain is usually sufficient and is accomplished with placement of a nasojejunal feeding tube past the point of duodenal compression. When conservative therapy fails, laparoscopic duodenojejunostomy can provide definitive relief of the obstruction. PMID:25829884

    Objective Spinal cord stimulation (SCS) is an effective means of treatment of chronic neuropathic pain from failed back surgery syndrome (FBSS). Because the success of trial stimulation is an essential part of SCS, we investigated factors associated with success of trial stimulation. Methods Successful trial stimulation was possible in 26 of 44 patients (63.6%) who underwent insertion of electrodes for the treatment of chronic pain from FBSS. To investigate factors associated with successful trial stimulation, patients were classified into two groups (success and failure in trial). We investigated the following factors : age, sex, predominant pain areas (axial, limb, axial combined with limbs), number of operations, duration of preoperative pain, type of electrode (cylindrical/paddle), predominant type of pain (nociceptive, neuropathic, mixed), degree of sensory loss in painful areas, presence of motor weakness, and preoperative Visual Analogue Scale. Results There were no significant differences between the two groups in terms of age, degree of pain, number of operations, and duration of pain (p>0.05). Univariate analysis revealed that the type of electrode and presence of severe sensory deficits were significantly associated with the success of trial stimulation (p<0.05). However, the remaining variable, sex, type of pain, main location of pain, degree of pain duration, degree of sensory loss, and presence of motor weakness, were not associated with the trial success of SCS for FBSS. Conclusion Trial stimulation with paddle leads was more successful. If severe sensory deficits occur in the painful dermatomes in FBSS, trial stimulation were less effective. PMID:24527193

    There has traditionally been less concern regarding coronary anomalies with left-sided congenital heart lesions such as hypoplastic left heart syndrome (HLHS)or Shone complex than with other lesions. However, coronary anomalies in this setting can profoundly affect surgical intervention, particularly when surgical repair involves the ascending aorta. We describe four patients with congenital left-sided heart lesions in which left coronary artery (LCA) anomalies substantially affected intervention and outcome. In the first two cases, the coronary anomalies were not identified prospectively and resulted in surgical injury directly to the coronary or to its surrounding region. In the latter two cases, successful identification of the coronary anomaly preoperatively allowed for modification of surgical technique and/or intervention. We conclude that detailed coronary artery assessment should be part of the routine echocardiographic evaluation of congenital left-sided heart lesions that require surgery. PMID:18445061

    Superior mesenteric artery syndrome (SMAS) is defined as an obstruction of the third part of duodenum due to compression by the superior mesenteric artery. Although traumatic brain injury is a risk factor for SMAS, few cases of SMAS resulting from brain surgery have been reported. SMAS has been observed to occur following neurosurgical surgery in pediatric patients but, to the best of our knowledge, no such cases have been reported in adults. The present study reports the case of a 21-year-old female patient who developed SMAS after persistent vomiting and prolonged weight loss following cerebellar tumor resection and cranial irradiation. The SMAS was confirmed by computed tomography and resolved following successful nutritional management. PMID:26622529

Chest X-ray showed cardiomegaly with a deviation of the trachea and mediastinum to the right side. Two-dimensional echocardiography showed decreased flow across the right pulmonary artery, a small atrial septal defect (ASD) with a right-to-left shunt, and a dilated right atrium and right ventricle with severe tricuspid regurgitation suggestive of severe pulmonary hypertension. A silent large patent ductus arteriosus was also seen. Multiple detector computerized tomography aortogram confirmed the findings of absent right pulmonary artery and hypoplastic right lung with small cystic lesions suggestive of congenital cystic adenomatoid malformation in the right lower lobe. Hoarseness of voice was due to the left vocal cord palsy probably secondary to severe pulmonary hypertension (Ortner's syndrome).

    Coronary sinus oxygen saturation was measured continuously during incremental atrial pacing in 34 patients undergoing cardiac catheterisation. In eleven patients with normal coronary arteriograms, negative exercise tests, and no ST segment depression on the electrocardiogram, an increase in the rate of atrial pacing transiently decreased coronary sinus oxygen saturation but within 20 s oxygen saturation returned to the control value. In six patients with coronary artery disease ST segment depression developed during atrial pacing. The coronary sinus oxygen saturation fell and remained reduced until pacing was discontinued. The size of the fall of coronary sinus oxygen saturation increased with increasing heart rate. In seven patients with coronary artery disease the ST segments were unaltered during atrial pacing and coronary sinus oxygen saturation did not fall. Ten patients with syndrome X were studied. In six ST segment depression developed on atrial pacing. In five, three of whom developed ST segment depression, the changes in coronary sinus oxygen saturation during atrial pacing were similar to those observed in patients without any evidence of coronary artery disease. In three, all of whom developed ST segment depression, coronary sinus oxygen saturation gradually increased throughout the period of atrial pacing. In two patients coronary sinus oxygen saturation fell in a manner similar to that observed in patients with obstructive coronary artery disease who developed ST segment depression on pacing. Thus regulation of coronary blood flow in normal persons in response to an increase of heart rate is rapid. Oxygen extraction across the coronary bed can increase by up to 30% and a persistent increase in oxygen extraction is an indicator of myocardial ischaemia. The term "syndrome X" does not describe a homogeneous group of patients but in the majority coronary sinus oxygen saturation does not fall despite symptoms and changes on the electrocardiogram

    Panax notoginseng saponins (PNS) are major components of Panax notoginseng, a herb with established clinical efficacy against vascular diseases. SHRSP.Z-Lepr(fa) /IzmDmcr (SHRSP.ZF) rats, a new animal model for metabolic syndrome, display an impaired vasorelaxation response in aortas and mesenteric arteries that is mediated by nitric oxide (NO). This study investigated whether PNS and its components can ameliorate this vascular dysfunction in SHRSP.ZF rats. In an in vitro study, in the presence or absence of PNS and its components, vasodilation in response to nitroprusside was determined from myographs under isometric tension conditions in aortas and mesenteric arteries from male SHRSP.ZF rats at 18-20 weeks of age. In an in vivo study, PNS (30 mg/kg per day) was orally administered to SHRSP.ZF rats from 8 to 20 weeks of age. In vitro treatment with PNS and Ginsenoside Rb1 increased nitroprusside-induced relaxation of aortas and mesenteric arteries in SHRSP.ZF rats. The PNS-induced increase was not affected by a nitric oxide (NO) synthase inhibitor or endothelium denudation. Relaxation in response to a cell-permeable cGMP analogue was increased by PNS, but cGMP accumulation by nitroprusside was not altered. In vivo treatment with PNS in SHRSP.ZF rats lowered blood pressure and increased relaxation and the expression of soluble guanylyl cyclase protein in arteries, without affecting metabolic abnormalities. These results indicate that PNS causes an increase in vasodilation in response to NO and a decrease in blood pressure, resulting in protection against vascular dysfunction in SHRSP.ZF rats. PNS might be beneficial in alleviating impaired vasodilation in metabolic syndrome. PMID:26784885

    Moyamoya disease leads to the formation of stenosis in the cerebrovasculature. A superficial temporal artery to middle cerebral artery (STA-MCA) bypass is an effective treatment for the disease, yet it is usually associated with postoperative cerebral hyperperfusion syndrome (CHS). This study aimed to evaluate cerebral hemodynamic changes immediately after surgery and assess whether a semiquantitative analysis of an intraoperative magnetic resonance perfusion-weighted image (PWI) is useful for predicting postoperative CHS. Fourteen patients who underwent the STA-MCA bypass surgery were included in this study. An atlas-based registration method was employed for studying hemodynamics in different cerebral regions. Pre- versus intraoperative and group-wise comparisons were conducted to evaluate the hemodynamic changes. A postoperative increase in relative cerebral blood flow (CBF) at the terminal MCA territory (P = 0.035) and drop in relative mean-time-transit at the central MCA territory (P = 0.012) were observed in all patients. However, a significant raise in the increasing ratio of relative-CBF at the terminal MCA territory was only found in CHS patients (P = 0.023). The cerebrovascular changes of the patients after revascularization treatment were confirmed. Intraoperative PWI might be helpful in predicting the change in relative-CBF at MCA terminal territory which might indicate a risk of CHS. PMID:26365751

We briefly reviewed the literature of similar cases and tried to analyze the possible pathophysiological relationship between these findings. Moreover, this case highlights the importance of a multidisciplinary management of these patients to better decide between a medical and a surgical and/or endovascular treatment. PMID:27594955

    Antiphospholipid antibody syndrome (APLAS) characterises a clinical condition of arterial and venous thrombosis associated with phospholipids directed antibodies. APLAS occurs in 2% of the general population. However, one study demonstrated that 7.1% of hospitalised patients were tested positive for at least one of the three anticardiolipin antibody idiotype. Antiphospholipid antibodies often inhibit phospholipids dependent coagulation in vitro and interfere with laboratory testing of hemostasis. Therefore, the management of anticoagulation during cardiopulmonary bypass can be quite challenging in these patients. Here, we present a case of right atrial mass removal and pulmonary thrombectomy in a patient of APLAS. PMID:20075534

    An 85-year-old man presented with a rare large aneurysm of the extracranial internal carotid artery (ICA) due to acute otitis media manifesting as Vernet's syndrome 2 weeks after the diagnosis of right acute otitis media. Angiography of the right extracranial ICA demonstrated an irregularly shaped large aneurysm with partial thrombosis. The aneurysm was treated by proximal ICA occlusion using endovascular coils. The ICA mycotic aneurysm was triggered by acute otitis media, and induced Vernet's syndrome as a result of direct compression to the jugular foramen. Extracranial ICA aneurysms due to focal infection should be considered in the differential diagnosis of lower cranial nerve palsy, although the incidence is thought to be very low. PMID:20098025

    Background: Intracranial pressure (ICP) monitoring is not routinely used during complex spinal deformity correction surgery. The authors report a 66-year-old male who during thoracolumbar deformity surgery required the placement of an ICP monitor due to the underlying history of a superior vena cava syndrome (e.g., s/p right jugular stent). Case Description: A 66-year-old male with multiple prior lumbar spinal procedures presented with lower back and bilateral lower extremity pain, paresthesias, and weakness. He had a history of chronic left internal jugular and brachiocephalic venous occlusion (e.g., he had a right internal jugular stent). During deformity surgery, a frontal intraparenchymal ICP monitor was placed. During the early portion of the operation, bed adjustments (increasing reverse trendelenburg position) were required to compensate for ICP elevations as high as 30 mm Hg. A subsequent inadvertent durotomy during decompression lowered the ICP to <5 mm Hg; no further ICP spikes occurred. His postoperative course was uneventful, and 14-month later, he was dramatically improved. Conclusion: ICP monitoring may be a useful adjunct for patient safety in selected patients who are at risk for developing intracranial hypertension during extensive spinal deformity surgery.

    The present study aims to compare neuropsychological performance of patients following anterior communicating artery aneurysm rupture (ACoA) with that of patients with alcoholic Korsakoff syndrome (AKS). Fifteen ACoA patients and ten age-and education-matched AKS patients were included in the study. All the patients were tested at least one year post onset of their illness at a stable condition. The WAIS and forward digit span scores of AKS were also matched to ACoA, and simple attention and general intelligence were well preserved both in ACoA and AKS. Frontal function as measured by the Wisconsin card sorting test (Keio version) (KWCST) was equivalently impaired in the two groups. Anterograde memory as measured by Wechsler memory scale subtests, serial seven word learning test, Rey auditory verbal learning test, and logical memorizing test (Luria's paired word-picture association), was more severely impaired in AKS than ACoA in contrast to the comparable attention, intelligence, and frontal function: (1) memory tasks with low correlations to KWCST (serial word learning tasks and paired verbal associates), reflecting primary simple serial memorizing, and (2) memory tasks with high correlations to KWCST (logical memory and logical memorizing), reflecting higher and complicated strategic mnemonic activities. However, the correlations between these anterograde memory subtests and KWCST were substantially equivalent in ACoA and AKS. This suggests that the differences in anterograde amnesia demonstrated in ACoA and AKS may be of quantitative, not of qualitative property. The extent of deficits in semantic encoding as measured by Wickens' release from proactive interference paradigm (PI release) was also milder in ACoA than AKS. Both AKS and ACoA failed to show PI release in contrast to normal PI release demonstrated in age-matched ten healthy subjects. PI release in ACoA, however, was in between AKS and healthy subjects. The results were interpreted in the light of a

    Medial medullary syndrome (MMS) is a rare type of stroke which results due to occlusion of the anterior spinal artery or vertebral artery or its branches. In this case report we present a patient who developed MMS secondary to Takayasu arteritis (TA). TA is a chronic inflammatory arteritis primarily involving the arch of aorta and its branches, which in our patient resulted in occlusion of subclavian arteries as well as infarction of the medial medulla bilaterally. To our knowledge this is the first time that MMS has been found to occur secondary to TA. PMID:23943806

    Ehlers-Danlos syndrome encompasses a group of inherited disorders of connective tissue, some of which are characterised by abnormalities of collagen metabolism. The chromosomal location, identified genes and biochemical defects, inheritance pattern, and clinical features for the various known subtypes are outlined. Prenatal diagnosis is possible for types IV, VI, VIIA1, and VIIA2. An unusual presentation of type IV Ehlers-Danlos syndrome in a 16 year old boy with an anterior myocardial infarction resulting from dissection of the left anterior descending coronary artery is reported here. A clinical diagnosis of type IV Ehlers-Danlos syndrome was made subsequently and confirmed by the reduced production, impaired secretion, and abnormally slow electrophoretic migration of type III collagen, indicating an underlying mutation in the COL3A1 gene. This patient represents the first case of type IV Ehlers-Danlos syndrome with symptomatic coronary artery dissection. Images PMID:7546986

    In rat tail artery (RTA), spinal cord injury (SCI) increases nerve-evoked contractions and the contribution of L-type Ca2+ channels to these responses. In RTAs from unoperated rats, these channels play a minor role in contractions and Bay K8644 (L-type channel agonist) mimics the effects of SCI. Here we investigated the mechanisms underlying the facilitatory actions of SCI and Bay K8644 on nerve-evoked contractions of RTAs and the hypothesis that Ca2+ entering via L-type Ca2+ channels is rapidly sequestered by the sarcoplasmic reticulum (SR) limiting its role in contraction. In situ electrochemical detection of noradrenaline was used to assess if Bay K8644 increased noradrenaline release. Perforated patch recordings were used to assess if SCI changed the Ca2+ current recorded in RTA myocytes. Wire myography was used to assess if SCI modified the effects of Bay K8644 and of interrupting SR Ca2+ uptake on nerve-evoked contractions. Bay K8644 did not change noradrenaline-induced oxidation currents. Neither the size nor gating of Ca2+ currents differed between myocytes from sham-operated (control) and SCI rats. Bay K8644 increased nerve-evoked contractions in RTAs from both control and SCI rats, but the magnitude of this effect was reduced by SCI. By contrast, depleting SR Ca2+ stores with ryanodine or cyclopiazonic acid selectively increased nerve-evoked contractions in control RTAs. Cyclopiazonic acid also selectively increased the blockade of these responses by nifedipine (L-type channel blocker) in control RTAs, whereas ryanodine increased the blockade produced by nifedipine in both groups of RTAs. These findings suggest that Ca2+ entering via L-type channels is normally rapidly sequestered limiting its access to the contractile mechanism. Furthermore, the findings suggest SCI reduces the role of this mechanism. PMID:25350563

    The purpose of this study was to investigate the feasibility of inducing ocular ischemic syndrome in spontaneously hypertensive rats. Hypertensive and normotensive Wistar-Kyoto rats had bilateral occlusion or sham surgery. They were divided into 4 groups: (1) hypertensive-ischemia, (2) hypertensive-sham, (3) normotensive-ischemia, and (4) normotensive-sham. Four months after the operation, the global changes of the eye and pupillary light reflex were assessed. Then each rat was perfused, and randomly one of the bulbuses oculi was prepared as retinal flat mounts for investigation of vascular changes. The opposite eyeball was prepared as a paraffin section for observation of the linear density of retinal ganglion cells and for thickness measurement. One hypertensive-ischemia rat had a cataract in one eye and another rat in the same group had bulbus oculi collapse in one eye. The light reflex disappeared in 13.33% of hypertensive-ischemia rats, and the rest of the hypertensive-ischemia rats and normotensive-ischemia rats had slow reflex. Compared with the respective controls, the peripheral retinal vascular network in hypertensive-ischemia and normotensive-ischemia rats was sparse; linear density of the retinal ganglion cells was significantly reduced; and the retinal thickness was reduced. Compared with normotensive-ischemia rats, the hypertensive-ischemia rats demonstrated more severe changes. After bilateral common carotic artery occlusion, the eyes of hypertensive rats developed various pathological changes similar to those of ocular ischemic syndrome. In conclusion, an animal model for ocular ischemic syndrome can be created by bilateral common carotid artery occlusion in spontaneously hypertensive rats.

    Nearly all children with MPS IVA develop skeletal deformities affecting the spine. At the atlanto-axial spine, odontoid hypoplasia occurs. GAG deposition around the dens, leads to peri-odontoid infiltration. Transverse/alar ligament incompetence causes instability. Atlanto-axial instability is associated with cord compression and myelopathy, leading to major morbidity and mortality. Intervention is often required. Does the presence of widened bullet shaped vertebra in platyspondily encroach on the spinal canal and cause spinal stenosis in MPS IVA? So far, there have been no standardised morphometric measurements of the paediatric MPS IVA cervical spine to evaluate whether there is pre-existing spinal stenosis predisposing to compressive myelopathy or whether this is purely an acquired process secondary to instability and compression. This study provides the first radiological quantitative analysis of the cervical spine and spinal cord in a series of affected children. MRI morphometry indicates that the MPS IVA spine is narrower at C1-2 level giving an inverted funnel shape. There is no evidence of a reduction in the Torg ratio (canal-body ratio) in the cervical spine. The spinal canal does not exceed 11 mm at any level, significantly smaller than normal historical cohorts (14 mm). The sagittal diameter and axial surface area of both spinal canal and cord are reduced. C1-2 level cord compression was evident in the canal-cord ratio but the Torg ratio was not predictive of cord compression. In MPS IVA the reduction in the space available for the cord (SAC) is multifactorial rather than due to congenital spinal stenosis. PMID:23404316

    A 40-year-old man who presented with left hemiparesis was admitted to our hospital. He had tachycardia and a fever. He had a 25-year history of insulin therapy for diabetes mellitus. Brain magnetic resonance (MR) images showed fresh infarction in the right hemisphere, and carotid ultrasonography showed stenosis of the right internal carotid artery (ICA). We determined that atherothrombotic brain infarction had likely occurred. After admission, the right ICA became narrow and finally occluded. Computed tomography revealed the presence of a thrombus in the right ICA, and gadolinium-enhanced MRA showed vasculitis of the ICA. In laboratory tests, his thyroid hormones were elevated. He was diagnosed with hyperthyroidism. After treatment, the tachycardia and high fever were improved. Because of a positive anti-glutamic acid decarboxylase antibody test result, he was diagnosed with insulin-dependent diabetes mellitus. We found that he had anti-phospholipid antibody syndrome because he was positive for anti-beta-glycoprotein I antibody. These findings suggested that his condition was autoimmune polyglandular syndrome type 3. He received prednisolone and warfarin. After 3 months, his neurological findings were improved; however, occlusion of the ICA remained. Autoimmunity was considered to be the cause of ICA occlusion. Ischemic stroke with autoimmune polyglandular syndrome is very rare and is associated with progressive carotid lesions in juvenile patients. It is necessary to diagnose and treat this condition as soon as possible. PMID:23892964

    We report a patient with Trousseau syndrome who presented with repeated acute middle cerebral artery (MCA) occlusion, which was successfully treated by performing mechanical thrombectomy. A 66-year-old man with a lung lesion and abdominal lymph node swelling experienced a sudden onset of left hemiparesis. Magnetic resonance angiography (MRA) revealed a right MCA occlusion. Perfusion-weighted imaging revealed reduced cerebral blood flow in the right MCA territory. Complete recanalization of the occluded vessel was achieved by performing mechanical thrombectomy, and his symptoms remarkably disappeared. Twenty days after the procedure, he experienced right hemiparesis and total aphasia. MRA revealed a left MCA occlusion, which was located on the contralateral side of the first occlusion. The second mechanical thrombectomy was successfully performed, and complete recanalization was successfully achieved. Right hemiparesis improved after the procedure. Histological examination of the retrieved clots revealed coagulated fibrin and platelets. Cytodiagnosis of pleural effusion revealed adenocarcinoma, and he was diagnosed with lung adenocarcinoma and cancerous pleurisy. Trousseau syndrome was the presumed primary cause of the patient's tendency for thrombogenesis.

    The anomalous origin of the left coronary artery from the pulmonary artery - known as Bland-White-Garland syndrome - is a rare congenital malformation that affects 1 in 300,000 live births. Most patients die in infancy without any surgical treatment. Some patients who survive past childhood often have varying symptoms such as myocardial ischemia, impaired left ventricular function, mitral regurgitation, and progressive heart failure, depending on the development collateral circulation. In the present report, we describe a procedure wherein the left coronary artery ostium was translocated through the transverse sinus of the pericardium in a 43-year-old mother with Bland-White-Garland syndrome and concomitant mitral regurgitation and report on the associated midterm results.

    The development of arterial hypertension after KTX is a well-known complication. HUS is a systemic disease associated with arterial hypertension during long-term follow-up. Our goal was to report on the severity of arterial hypertension after KTX in patients with typical and atypical HUS. We analyzed the course of 197 patients with HUS, of which 22 (n = 10 with typical HUS; n = 12 with atypical HUS) developed ESRF and received KTX as renal replacement therapy. We analyzed data from 1766 casual BP and 85 24-h ABPM measurements. In addition, we evaluated the used antihypertensive strategy. Comparison between the two patient groups revealed that patients with atypical HUS had significantly higher casual SBP-SDS and DBP-SDS values after KTX despite similar intensity of antihypertensive treatment. These data were supported by analysis of ABPM profiles showing comparable results for the interval 1-5 yr after KTX. Patients with atypical HUS had a greater severity of arterial hypertension despite similar treatment strategies and intensity of treatment. Our observation, even though in a small cohort, supports recent genetic studies showing arterial hypertension closely associated with HUS-causing mutations in patients with atypical HUS.

    Costello syndrome is a rasopathy caused by germline mutations in the proto-oncogene HRAS. Its presentation includes failure-to-thrive with macrocephaly, characteristic facial features, hypertrophic cardiomyopathy, papillomata, malignant tumors, and cognitive impairment. In a systematic review we found absolute or relative macrocephaly (100%), ventriculomegaly (50%), and other abnormalities on brain and spinal cord imaging studies in 27/28 individuals. Posterior fossa crowding with cerebellar tonsillar herniation (CBTH) was noted in 27/28 (96%), and in 10/17 (59%) with serial studies posterior fossa crowding progressed. Sequelae of posterior fossa crowding and CBTH included hydrocephalus requiring shunt or ventriculostomy (25%), Chiari 1 malformation (32%) and syrinx formation (25%). Our data reveal macrocephaly with progressive frontal bossing and CBTH, documenting an ongoing process rather than a static congenital anomaly. Comparison of images obtained in young infants to subsequent studies demonstrated postnatal development of posterior fossa crowding. This process of evolving megalencephaly and cerebellar enlargement is in keeping with mouse model data, delineating abnormal genesis of neurons and glia, resulting in an increased number of astrocytes and enlarged brain volume. In Costello syndrome and macrocephaly-capillary malformation syndrome disproportionate brain growth is the main factor resulting in postnatal CBTH and Chiari 1 malformation. PMID:20425820

    Abstract Shrunken Pore Syndrome was recently suggested for the pathophysiologic state in patients characterized by an estimation of their glomerular filtration rate (GFR) based upon cystatin  C, which is lower or equal to 60% of their estimated GFR based upon creatinine, i.e. when eGFRcystatin  C ≤ 60% of eGFRcreatinine. Not only the cystatin  C level, but also the levels of other low molecular mass proteins are increased in this condition. The preoperative plasma levels of cystatin  C and creatinine were measured in 1638 patients undergoing elective coronary artery bypass grafting. eGFRcystatin  C and eGFRcreatinine were calculated using two pairs of estimating equations, CAPA and LMrev, and CKD-EPIcystatin  C and CKD-EPIcreatinine, respectively. The Shrunken Pore Syndrome was present in 2.1% of the patients as defined by the CAPA and LMrev equations and in 5.7% of the patients as defined by the CKD-EPIcystatin  C and CKD-EPIcreatinine equations. The patients were studied over a median follow-up time of 3.5 years (2.0–5.0 years) and the mortality determined. Shrunken Pore Syndrome defined by both pairs of equations was a strong, independent, predictor of long-term mortality as evaluated by Cox analysis and as illustrated by Kaplan-Meier curves. Increased mortality was observed also for the subgroups of patients with GFR above or below 60 mL/min/1.73 m2. Changing the cut-off level from 60 to 70% for the CAPA and LMrev equations increased the number of patients with Shrunken Pore Syndrome to 6.5%, still displaying increased mortality. PMID:26647957

    OBJECTIVE The aim of this paper was to compare the severity of the initial neurological injury as well as the early changes in the American Spinal Injury Association (ASIA) motor score (AMS) between central cord syndrome (CCS) patients with and without an increased T2 signal intensity in their spinal cord. METHODS Patients with CCS were identified and stratified based on the presence of increased T2 signal intensity in their spinal cord. The severity of the initial neurological injury and the progression of the neurological injury over the 1st week were measured according to the patient's AMS. The effect of age, sex, congenital stenosis, surgery within 24 hours, and surgery in the initial hospitalization on the change in AMS was determined using an analysis of variance. RESULTS Patients with increased signal intensity had a more severe initial neurological injury (AMS 57.6 vs 75.3, respectively, p = 0.01). However, the change in AMS over the 1st week was less severe in patients with an increase in T2 signal intensity (-0.85 vs -4.3, p = 0.07). Analysis of variance did not find that age, sex, Injury Severity Score, congenital stenosis, surgery within 24 hours, or surgery during the initial hospitalization affected the change in AMS. CONCLUSIONS The neurological injury is different between patients with and without an increased T2 signal intensity. Patients with an increased T2 signal intensity are likely to have a more severe initial neurological deficit but will have relatively minimal early neurological deterioration. Comparatively, patients without an increase in the T2 signal intensity will likely have a less severe initial injury but can expect to have a slight decline in neurological function in the 1st week.

  11. Arterial Tortuosity Syndrome reveals function of dehydroascorbic acid in collagen and elastin synthesis: Implications for skin care.

    2016-02-01

    Some investigations in Arterial Tortuosity Syndrome (ATS) suggest that impaired intracellular transport of the oxidized form of vitamin C (dehydroascorbic acid, DHAA) is at the core of the pathogenesis. Lack of vitamin C for lysyl- and prolyl-hydroxylase activity may explain the defects in collagen and elastin formation found in ATS, and draws strong parallels between ATS and scurvy. Topically applied vitamin C has a well-established basis in the field of skin care, and part of its benefit is attributed to proper collagen formation in the skin. The ATS studies suggest that DHAA transport is necessary for normal skin collagen formation, and this has implications as to the forms of vitamin C best-suited for topical skin care. PMID:26826631

    Systemic onset juvenile idiopathic arthritis (SoJIA) is characterized by arthritis, fever and visceral organ involvement including hepatosplenomegaly, lympadenopathy and serositis. This is a case of SoJIA misdiagnosed as Kawasaki disease (KD) and developed machrophage activation syndrome (MAS) secondary to Ebstein-Barr virus (EBV) infection. It is presented to point out the conditions that may come along. First of all, SoJIA should be kept in mind while making the differential diagnosis of coronary arterial ectasias and dilatations usually seen in vasculitic diseases like KD. Second, as a very fatal complication MAS should always be considered while following a patient with the diagnosis of SoJIA. Infections like EBV may be the potential triggers for development of MAS especially in immunesupressed patients. PMID:27411422

    Complex regional pain syndrome (CRPS) is a neuropathic pain condition that is characterized by vasomotor, sensory, sudomotor, and motor symptoms. Spinal cord stimulation (SCS) has been successfully utilized for the treatment of pain refractory to conventional therapies. We present a case of a previously highly functioning 54-year-old female who developed a rarely reported case of idiopathic CRPS of the right ankle which spontaneously occurred four months after an uncomplicated anterior cervical disc fusion. This condition resulted in severe pain and functional impairment that was unresponsive to pharmacological management. The patient's rehabilitation was severely stymied by her excruciating pain. However, with the initiation of spinal cord stimulation, her pain was adequately controlled allowing for progression to full unassisted ambulation, advancing functional capacity, and improving quality of life. This case report supports the concept that rapid progression to neuromodulation, rather than delays that occur due to attempts at serial sympathetic blocks, may better control symptoms leading allowing for a more meaningful recovery.

    Objective Despite standardization in care, heterogeneity in outcomes persists for infants with hypoplastic left heart syndrome (HLHS). One potential factor is in utero stressors. Uteroplacental insufficiency (UPI) induces systemic vascular and myocardial adaptations in the absence of structural heart disease. The effect of UPI in HLHS is unknown. Methods We retrospectively analyzed infants undergoing Norwood palliation for HLHS from 2007 to 2012. We compared the umbilical artery systolic to diastolic (SD) ratio to growth outcomes and post-operative right ventricular (RV) function. Results Forty three infants met our inclusion criteria. Fetuses without a declining SD ratio with advancing gestational age had asymmetric birth biometry, defined as birth weight minus head circumference z scores (−0.9 vs. −0.05, p<0.01). The SD ratio near the end of gestation negatively correlated with asymmetric birth biometry (R=−0.521, p<0.01) and interstage growth (R=−0.49, p=0.04). Males with higher SD ratios had a greater post-operative incidence of abnormal RV function. Conclusions A higher umbilical artery SD ratio was associated with asymmetric prenatal growth, poor weight gain and decreased myocardial performance in infants with HLHS. Better understanding UPI's effects on cardiovascular development and metabolism in HLHS will help identify new strategies for targeting morbidity in this high risk population. PMID:24190763

    Dialysis-associated steal syndrome (DASS) is a potentially devastating complication. As a new surgical technique, proximalization of the arterial inflow (PAI) has been described recently to be of good effect in case of DASS. As there has not yet been much general familiarity with this technique, our aim with this prospective study was to establish its indication for a special group of patients who developed advanced DASS (finger necrosis) following autogenous hemodialysis access (HA). Twenty-three patients (18 brachial, five wrist HA) with advanced DASS underwent PAI. Graft material included either heparinized (13 patients) or nonheparinized (10 patients) polytetrafluoroethylene prosthetic material. Vascular function was evaluated pre- and postoperatively with duplex ultrasound. Procedural success was determined by restitution of limb circulation and preservation of the HA. In 15 cases (65%) symptoms of DASS disappeared completely, and in six patients (26%) adequate wound healing with improvement of symptoms was achieved. Symptoms were persistent in two patients (9%) who had tissue loss >1 cm at the fingertips. Overall there was a significant increase in radial artery flow velocity (from 35.65 +/- 7.69 to 55.21 +/- 8.51 cm/sec, p < 0.005) after PAI. A decrease of fistula flow (from 1.38 +/- 0.48 to 0.94 +/- 0.14 L/min, p = 0.003) was measured in patients with elbow HA but not in patients with wrist HA. Secondary patency after 18 months was 85%. PAI effected an improvement in distal radial artery circulation with an additional banding component in elbow HA. We found that PAI led to good clinical success, especially in patients developing small finger necrosis as a form of advanced DASS. However, in case of severe tissue loss (>1 cm in diameter), PAI was not successful (n = 2). In such situations, other treatment options have to be discussed. PMID:18973988

    Background Many studies have shown that evidence supporting the relationship between low bone mineral density (BMD) and coronary artery disease (CAD) has been increasing. There is a significant increase of myocardial infarction in men with low BMD. Purpose We aimed to detect the relationship between BMD and CAD in patients whose CAD was detected with coronary angiography, and its severity and prevalence was detected with Gensini score. Methods A total of 55 patients were selected who were found to have single or multiple infarctions through using coronary angiography in the cardiology clinic. The CAD severity was evaluated by calculating the Gensini score. These patients were divided into two groups: mild CAD and severe CAD groups. Femur bone mineral density (FBMD) was measured with dual energy X-ray absorptiometry. T score values were determined to be normal if the values were >−1.0 (n=22, 40%), and osteopenia–osteoporosis (osteopenic syndrome) if the T score values were ≤−1 (n=33, 60%). Results The FBMD of severe CAD according to the Gensini risk score was found to be significantly lower. FBMD values in patients decreased as their Gensini scores increased. Conclusion There was a significant relationship between CAD and osteopenic syndrome. FBMD level in men with severe CAD is significantly low when compared with patients who have mild CAD.

    Carpal tunnel syndrome presenting as a trophic disorder in the hand is unusual. We report the case of a 66 year old man in whom nerve conduction tests confirmed compression of the median nerve in the carpal tunnel, and vasospasm in the corresponding area was demonstrated by arteriography for, we believe, the first time. Simple decompression of the carpal tunnel brought about total recovery. The mechanism of the autonomic disorders found in carpal tunnel syndrome remains controversial. The clinical case that we report objectively demonstrates the vasospasm caused by the compression of the autonomic fibres of the median nerve. PMID:15754710

    Patients with spinal cord injury show upper motor neuron dysfunction below the level of the lesion. Some patients with cervical and high thoracic injuries show unexpected lower leg atrophy and ankle jerk abnormalities together with persistence of urinary retention. Clinical, neurophysiological and urodynamic findings in 130 patients with cervical and thoracic injuries showed that 18 patients had additional lumbosacral dysfunction. Three patients had radiological findings demonstrating a second lesion of the lower spine. The remaining 15 patients, however, did not have any obvious bony lesion to account for the lumbosacral dysfunction. Atypical neurological findings, abnormal neurophysiological testing and aberrant detrusor behaviour were the essence of the occult lumbosacral dysfunction in cervical and thoracic spinal cord injury patients. Recognition of the presence of a double lesion was important for care of the neuropathic bladder and pain in addition to understanding the unexpected clinical signs. Images PMID:3585385

    Certain Acute Clinical presentations are highly suggestive of stroke caused by specific mechanisms. One example of this would be the sudden onset of aphasia without hemiparesis often reflecting cerebral embolism, frequently from a cardiac source. Posterior reversible encephalopathy syndrome (PRES) describes a usually reversible neurologic syndrome with a variety of presenting symptoms from headache, altered mental status, seizures, vomiting, diminished spontaneity and speech, abnormalities of visual perception and visual loss. We report a patient presenting with elevated blood pressure, CT characteristics of PRES but a highly circumscribed neurologic syndrome (Wernicke's Aphasia without hemiparesis) suggestive of a cardioembolic stroke affecting the left MCA territory. That is, PRES mimicked a focal stroke syndrome. The importance of recognizing this possibility is that his deficits resolved with blood pressure control, while other treatments, such as intensifying his anticoagulation would have been inappropriate. In addition, allowing his blood pressure to remain elevated as is often done in the setting of an acute stroke might have perpetuated the underlying pathophysiology of PRES leading to a worse clinical outcome. For this reason PRES needs to be recognized quickly and treated appropriately. PMID:22371821

A blood examination revealed high plasma glucose and thyroid hormone levels and metabolic acidosis. She was therefore diagnosed with both diabetic ketoacidosis (DKA) and hyperthyroidism. Nausea and vomiting continued intermittently despite the administration of saline and insulin. The patient was further diagnosed with superior mesenteric artery syndrome (SMAS) after abdominal computed tomography revealed that a horizontal portion of the duodenum was sandwiched between the aorta and the superior mesenteric artery.

    Objective. To evaluate the efficacy of subclavian stenosis percutaneous transfemoral angioplasty (PTA)-treatment in patients with intermittent or complete subclavian steal syndrome (SSS), and coronary-subclavian steal syndrome (C-SSS) after left internal mammary artery-interventricular anterior artery (LIMA-IVA) by pass graft. Methods. We studied 42 patients with coronary subclavian steal syndrome subdivided in two groups; the first group consisted of 15 patients who presented an intermittent vertebral-subclavian steal, while the second group consisted of 27 patients with a complete vertebral-subclavian steal. All patients were treated with angioplasty and stent application and were followed up for a period of 5 years by echocolordoppler examination to evaluate any subclavian restenosis. Results. Subclavian restenosis was significantly increased in patients with a complete subclavian steal syndrome. The restenosis rate was 6.67% in the first group and 40.75% in the second group, These patients had 9.1 fold-increase risk (CI confidence interval 0.95-86.48) in restenosis. Conclusion. Patients with a complete subclavian and coronary steal syndrome present a higher risk of subclavian restenosis.

    OBJECTIVE Metabolic syndrome (MS) is common in patients with chronic kidney disease (CKD), but its contribution to arterial stiffness and endothelial dysfunction in CKD is not well defined. We hypothesized that risk factors for MS would independently predict arterial stiffness and endothelial dysfunction in CKD patients. RESEARCH DESIGN AND METHODS Risk factors for MS, carotid-femoral pulse wave velocity (CF-PWV) and flow-mediated dilation (FMD) as measures of arterial stiffness and endothelial dysfunction, respectively, were assessed in 113 minimally comorbid CKD patients and in 23 matched control subjects. RESULTS CF-PWV correlated with systolic blood pressure (SBP), waist circumference, and plasma glucose (r2 = 0.25, 0.09, and 0.09; P < 0.01 for all). FMD correlated with SBP (r2 = 0.09; P < 0.01) and waist circumference (r2 = 0.03; P < 0.05). CF-PWV increased progressively (r2 = 0.07; P < 0.01) with increasing number of risk factors for MS. In multiple linear regression, SBP and waist circumference were independent determinants of CF-PWV, whereas only SBP predicted FMD. CONCLUSIONS The number of MS risk factors is an important determinant of arterial stiffness in CKD patients irrespective of the degree of renal impairment. Although BP remains the major determinant of arterial stiffness and endothelial dysfunction, waist circumference independently predicts arterial stiffness. MS risk factors, particularly abdominal girth, are potential targets for future interventional studies in patients with CKD. PMID:22648437

    Optimization of platelet inhibition in patients with acute coronary syndromes reduces the risk for ischemic events, but at the same time increases the risk for bleeding. There are several predictors of bleeding risk in patients with acute coronary syndromes. These include demographic variables such as advanced age, female gender, low body weight, concomitant diseases such as diabetes,renal insufficiency, noncardiac vascular disease such as cerebral vascular disease and a history of bleeding. It also includes the type of acute coronary syndromes such as patients presenting with ST segment elevation myocardial infarction, high killip class and low blood pressure. The diabetic population contains a higher proportion of patients who do not respond to antiplatelet drugs as expected and who also have more activated platelets that deserve very vigorous inhibition. The importance of dual antiplatelet therapy in patients undergoing balloon angioplasty and stenting is much discussed. Yet there are some questions which are to be answered clearly such as the following:- 1) In the need to balance the benefit of clot prevention with bleeding risk, is it better to continue dual antiplatelet therapy for longer than one year? 2) If so, is this benefit specific to drug eluting stents or to a more general population of stent patients? 3) Is the benefit mediated by prevention of stent thrombosis or is there a global reduction in cardiovascular risk? This review is to understand all these aspects and help a physician use antiplatelet drugs appropriately in day to day clinical practice for better patient outcomes. PMID:25672032

    Spinal tuberculosis (TB) is a significant form of TB, causing spinal deformity and paralysis. Early diagnosis and treatment are crucial for avoiding multivertebral destruction and are critical for improving outcomes in spinal TB. We believe that appropriate treatment method should be implemented at the early stage of this disease and that the Gulhane Askeri Tıp Akademisi classification system can be considered a practical guide for spinal TB treatment planning in all countries.

    2016-01-01

    Background/Aims: The CHADS2 score, used to predict the risk of ischemic stroke in atrial fibrillation (AF) patients, has been reported recently to predict ischemic stroke in patients with coronary heart disease, regardless of the presence of AF. However, little data are available regarding the relationship between the CHADS2 score and cardiovascular outcomes. Methods: This was a retrospective study on 104 patients admitted for acute coronary syndrome (ACS) who underwent coronary angiography, carotid ultrasound, and transthoracic echocardiography. Results: The mean age of the subjects was 60.1 ± 12.6 years. The CHADS2 score was as follows: 0 in 46 patients (44.2%), 1 in 31 (29.8%), 2 in 18 (17.3%), and ≥ 3 in 9 patients (8.7%). The left atrial volume index (LAVi) showed a positive correlation with the CHADS2 score (20.8 ± 5.9 for 0; 23.2 ± 6.7 for 1; 26.6 ± 10.8 for 2; and 30.3 ± 8.3 mL/m2 for ≥3; p = 0.001). The average carotid total plaque area was significantly increased with CHADS2 scores ≥ 2 (4.97 ± 7.17 mm2 vs. 15.52 ± 14.61 mm2; p = 0.002). Eight patients experienced cardiovascular or cerebrovascular (CCV) events during a mean evaluation period of 662 days. A CHADS2 score ≥ 3 was related to an increase in the risk of CCV events (hazard ratio, 14.31; 95% confidence interval, 3.53 to 58.06). Furthermore, LAVi and the severity of coronary artery obstructive disease were also associated with an increased risk of CCV events. Conclusions: The CHADS2 score may be a useful prognostic tool for predicting CCV events in ACS patients with documented coronary artery disease. PMID:26767860

    Different forms of Ehlers-Danlos syndrome (EDS) exist, with specific phenotypes and associated genes. Vascular EDS, caused by heterozygous mutations in the COL3A1 gene, is characterized by fragile vasculature with a high risk of catastrophic vascular events at a young age. Classic EDS, caused by heterozygous mutations in the COL5A1 or COL5A2 genes, is characterized by fragile, hyperextensible skin and joint laxity. To date, vessel rupture in four unrelated classic EDS patients with a confirmed COL5A1 mutation has been reported. We describe familial occurrence of a phenotype resembling vascular EDS in a mother and her two sons, who all died at an early age from arterial ruptures. Diagnostic Sanger sequencing in the proband failed to detect aberrations in COL3A1, COL1A1, COL1A2, TGFBR1, TGFBR2, SMAD3, and ACTA2. Next, the proband's DNA was analyzed using a next-generation sequencing approach targeting 554 genes linked to vascular disease (VASCULOME project). A novel heterozygous mutation in COL5A1 was detected, resulting in an essential glycine substitution at the C-terminal end of the triple helix domain (NM_000093.4:c.4610G>T; p.Gly1537Val). This mutation was also present in DNA isolated from autopsy material of the index's brother. No material was available from the mother, but the mutation was excluded in her parents, siblings and in the father of her sons, suggesting that the COL5A1 mutation occurred in the mother's genome de novo. In conclusion, we report familial occurrence of lethal arterial events caused by a COL5A1 mutation. PMID:25845371

    2015-01-01

    Background: Androgenic alopecia (AGA) is a common cosmetically and psychosocially distressing condition. High androgen level contributes to the development of atherosclerosis, thrombosis leading to hypertension and hypercholesterolemia. Objectives: To study the clinico-epidemiological profile of AGA and the presence of metabolic syndrome (MetS) and carotid artery atherosclerosis in male patients with early onset AGA as compared to controls. Materials and Methods: In this case-control study, 100 male patients of age 18-35 years with AGA and an equal number of age-matched healthy controls attending skin and STD OPD were included. Assessment of the degree of hair loss, evaluation of MetS and carotid artery color Doppler for the atherosclerotic plaque was done in all patients. Results: Statistically significant number of patients with early onset AGA 22/100 (22%) (P < 0.05) fulfilled the criteria for MetS compared to 8/100 (8%) in the control group. There were statistically significant differences in mean values of waist circumference, serum triglycerides, serum cholesterol, systolic blood pressure, diastolic blood pressure, fasting glucose concentration, and very low-density lipoprotein (LDL). However, no significant differences were observed in the mean values of high-density lipoprotein cholesterol and LDL cholesterol. The atherosclerotic plaque was found in two patients of the study group, and no plaque was found in control patients. Conclusion: We suggest that all men with AGA should be thoroughly investigated, and lifestyle changes should be started in the early period of life so as to reduce the risk of various problems associated with MetS. AGA can be considered as an early marker for MetS. PMID:26903742

    Introduction: Spinal Subdural hematoma is a rare cause of radiculopathy and spinal cord compression syndromes. It’s early diagnosis is essential. Chronological appearance of these bleeds vary on MRI. Case Report: A 56 year old man presented with progressive left lower limb radiculopathy and paraesthesias with claudication of three days duration. MRI revealed a subdural space occupying lesion compressing the cauda equina at L5-S1 level producing a ‘Y’ shaped dural sac (Y sign), which was hyperintense on T1W imaging and hypointense to cord on T2W image. The STIR sequence showed hyperintensity to cord. There was no history of bleeding diathesis. The patient underwent decompressive durotomy and biopsy which confirmed the diagnosis. Conclusion: Spinal subdural hematoma may present with rapidly progressive neurological symptoms. MRI is the investigation of choice. The knowledge of MRI appearance with respect to the chronological stage of the bleed is essential to avoid diagnostic and hence surgical dilemma PMID:27299051

    Functional popliteal artery entrapment syndrome (PAES) is an important and possibly underrecognized cause of exertional leg pain (ELP). As it is poorly understood, it is at risk of misdiagnosis and mismanagement. The features indicative of PAES are outlined, as it can share features with other causes of ELP. Investigating functional PAES is also fraught with potential problems and if it is performed incorrectly, it can result in false negative and false positive findings. A review of the current vascular investigations is provided, highlighting some of the limitations standard tests have in determining functional PAES. Once a clinical suspicion for PAES is satisfied, it is necessary to further distinguish the subcategories of anatomical and functional entrapment and the group of asymptomatic occluders. When definitive entrapment is confirmed, it is important to identify the level of entrapment so that precise intervention can be performed. Treatment strategies for functional PAES are discussed, including the possibility of a new, less invasive intervention of guided Botulinum toxin injection at the level of entrapment as an alternative to vascular surgery.

    Monochorionic twins are subjected to specific complications which originate in either imbalance or abnormality of the single placenta serving two twins. This unequal placental sharing can cause complications including twin-twin transfusion syndrome (TTTS), twin anemia-polycythemia sequence (TAPS), selective intrauterine growth restriction or twin reversed arterial perfusion sequence (TRAP). Monochorionicity also makes the management of these specific complications as well as that of a severe malformation in one twin hazardous since the spontaneous death of one twin exposes the co-twin to a risk of exsanguination into the dead twin and its placenta. The latter is responsible for the death of the co-twin in up to 20% of the cases and in ischemic sequelae in about the same proportions in the survivors. Although the symptoms of all these complications are very different, the keystone of their management comes down to either surgical destruction of the inter-twin anastomoses on the chorionic plate when aiming at dual survival or selective and permanent occlusion of the cord of a severely affected twin aiming at protecting the normal co-twin. This can be best achieved by fetoscopic selective laser coagulation and bipolar forceps cord coagulation respectively. PMID:20855238

    There is no formal association between premature coronary artery disease (CAD) and Prader-Willi syndrome despite its association with hyperlipidaemia, diabetes mellitus and hypertension. A 36-year-old man with Prader-Willi syndrome presented with acute breathlessness. Inflammatory markers were borderline elevated and chest radiography demonstrated unilateral diffuse alveolar shadowing. Bronchopneumonia was diagnosed and despite treatment with multiple courses of antimicrobial therapy, there was minimal symptomatic and radiographical improvement. A diagnosis of unilateral pulmonary oedema was suspected. Echocardiography was non-diagnostic due to body habitus and coronary angiography was deemed inappropriate due to uncertainty in diagnosis, invasiveness and pre-existing chronic kidney disease. Therefore, cardiac magnetic resonance was performed, confirming severe triple-vessel CAD. This case demonstrates a presentation of heart failure with unilateral chest radiograph changes in a young patient with Prader-Willi syndrome and severe premature CAD detected by multiparametric cardiac magnetic resonance imaging.

    The continuous changes in pulmonary hemodynamic properties in hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PoPH) have not been fully characterized in large animal models of HPS and PoPH. Beagle dog models of HPS and PoPH were induced by chronic common bile duct ligation and Sephadex microspheres, respectively. The model was validated by catheter examination and pathological analyses, and the hemodynamic characteristics of the models were observed. The results revealed that the cross-sectional area of the blood vessel was significantly increased in HPS models, but it was significantly decreased in the PoPH models. Furthermore, the resistance of pulmonary circulation was elevated in models of HPS, but it was decreased in models of PoPH. The present findings renew the traditional view that pulmonary hypertension is due to the enhanced peripheral resistance. PMID:26870333

    Introduction In the last two decades, ozone has emerged as a treatment for low back pain, applied by means of minimally invasive techniques. Objective The aim of this study is to assess the effect and safety of ozone therapy applied in the epidural space for chronic pain related to failed back surgery syndrome. Methods The investigators studied 13 sequential patients of both sexes, between 18 and 70 years old, with persistent chronic pain (more than six months) in the lumbar region and in the lower limbs related to failed back surgery syndrome (FBSS). Pain was classified as neuropathic and non-neuropathic regarding the topography (lumbar and lower limb), based on the DN4 (Douleur Neuropathique 4) questionnaire. The patients received the ozone gas in the lumbar epidural space via spinal-sacral endoscopy. Clinical evaluation was performed before, immediately after (24 hours), and 1, 3, and 6 months after intervention with visual analog scale and Oswestry Disability Index (ODI). Results Overall, the patients had 43.7% reduction of lumbar pain, 60.9% reduction in leg pain in six months followed by 44.0% of improvement in ODI. The reduction of pain and in the disability index was markedly greater in patients with non-neuropathic predominant pain, 95.2%, 80.6%, and 75.3% improvement in lumbar, leg pain, and ODI respectively, while neuropathic predominant pain patients experienced only 12.5%, 42.4%, and 20.9% improvement, also respectively. No neurological or infectious complications were observed acutely or during the follow-up. The present data suggests that epidural ozone might be a therapeutic option for persistent low back pain, especially in non-neuropathic predominant pain patients, but double-blind controlled studies are still required to prove its efficacy.

    Background Celiac artery stenosis (CAS) may be caused by atherosclerotic degeneration or compression exerted by the arched ligament of the diaphragm. Mitral valve prolapse (MVP) is the most common valvular disorder. There are no reports on an association between CAS and MVP. Methods 1560 (41%) out of 3780 consecutive patients undergoing echocardiographic assessment of MVP, had Doppler sonography of the celiac tract to detect CAS. Results CAS was found in 57 (3.7%) subjects (23 males and 34 females) none of whom complained of symptoms related to visceral ischemia. MVP was observed in 47 (82.4%) subjects with and 118 (7.9%) without CAS (p < 0.001). The agreement between MVP and CAS was 39% (95% CI 32–49%). PSV (Peak Systolic Velocity) was the only predictor of CAS in MPV patients (OR 0.24, 95% CI 0.08–0.69) as selected in a multivariate logistic model. Conclusion CAS and MVP seem to be significantly associated in patients undergoing consecutive ultrasonographic screening. PMID:15588321

    Spinal cord infarction is rare and represents a diagnostic challenge for many physicians. There are few reported cases worldwide with a prevalence of 1.2% of all strokes. Circulation to the spinal cord is supplied by a rich anastomosis. The anterior spinal artery supplies the anterior two thirds of the spinal cord and infarction to this area is marked by paralysis, spinothalamic sensory deficit and loss of sphincter control depending on where the lesion is. Treatment of spinal cord infarction focuses on rehabilitation with diverse outcomes. This report presents a case of acute spinal cord infarction with acquisition of MRI to aid diagnosis.

    Iliacus compartment syndrome is a rare retroperitoneal compartment neuropathy caused by bleeding within the iliacus muscle leading to hematoma formation and compression upon the femoral nerve, causing both sensory and motor deficits. A 75-year-old Caucasian man presented with severe right hip pain associated with motor and sensory deficit in the right lower extremity, 2 weeks post elective balloon aortic valvuloplasty for critical aortic stenosis. A non-contrast computed tomography scan revealed low-attenuation areas in keeping with an iliacus hematoma. An iliacus fasciotomy and hematoma evacuation was performed with retroperitoneal approach. The patient reported marked reduction in his groin pain with clinical improvement of the right hip flexion though the sensory deficit was unchanged. On Day 3, postoperatively the patient died from respiratory and multi-organ failure. Iliac hematomas are rare and can be caused by traumatic and non-traumatic injury, and can be exacerbated by complications of anticoagulant therapy. Delaying surgical evacuation of the hematoma can lead to prolonged or permanent disability. However, there are other reports describing good recovery with non-operative management. Non-surgical intervention is recommended if radiological studies do not explicitly confirm the presence of a discreet hematoma compressing the femoral nerve, unless progression of symptoms increases.

    The aim of this study is to define absolute and relative reliability of spectral indices of cardiovascular autonomic control in the supine position in women with fibromyalgia syndrome (FMS). Twenty-three women with FMS (age 48 ± 7 years) took part in the study. ECG, finger blood pressure, and respiration were continuously recorded in all participants at rest in baseline 1 (BL1) and after 15 days from BL1 (BL2). The power spectrum analysis provided two oscillatory components: low frequency (LF, 0.04-0.15 Hz) and high frequency (HF, 0.15-0.4 Hz) from the heart period (HP) variability and the LF oscillatory component from SAP variability (LFSAP). Absolute and relative reliability were rated by 95 % of the limit of random variation and intraclass correlation coefficient (ICC), respectively. No significant differences were observed between BL1 and BL2 for the spectral indices of HP and SAP variabilities. The 95 % limit of the random variation of these indices indicated that the values of repeated measurements were between 22 % higher and 0.2 % lower (more reliable parameter; average of HP variability) and 912.9 % higher and 0.2 % lower (less reliable parameter; LFSAP) than BL1. Conversely, the index of relative reliability (ICC) ranged from 0.23 to 0.70 indicating a good reliability. The spectral indices of cardiovascular autonomic control in women with FMS seem to present good relative reliability. Therefore, these indices can be useful as parameters to quantify if a variation was consistent and accurate in the retest besides adding crucial information for clinical research and clinical evaluation of FMS patients.

    The relation between coagulation and atherosclerosis has been extensively described, pointing towards a hypercoagulable state in patients with atherosclerosis, especially in young individuals. However, not all studies were conclusive. It is known that the metabolic syndrome (MetS), a risk factor for coronary artery disease (CAD), is related to a higher incidence of thrombo-embolic events. We hypothesised that individuals with CAD at a young age and MetS have an increased prothrombotic potential. It was the study objective to analyse the endogenous thrombin potential (ETP) and related thrombin generation parameters in patients with CAD before the age of 51 in men and 56 in women with and without MetS features and their healthy first-degree relatives. In this case-control study we included 118 CAD patients and 50 first-degree relatives (controls). Parameters of thrombin generation were obtained with calibrated automated thrombinography. An adjusted general linear model (GLM) showed a positive association between the peak thrombin levels and the presence of CAD at a young age. Based on the NCEP criteria we divided our patient group in CAD patients with and without MetS, and compared them to the controls without MetS. We showed that CAD patients with MetS have increased ETP levels, both in comparison with healthy first-degree relatives and with CAD patients without MetS. There were no differences in ETP between patients without MetS and healthy controls. In conclusion, this study shows that individuals with CAD at a young age and MetS features have an increased prothrombotic potential, compared to CAD patients without MetS. PMID:24306178

    BACKGROUND Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder associated with cardiovascular disease (CVD) risk factors and metabolic disturbances. This systematic review and meta-analysis was conducted to determine whether carotid intima-media thickness (CIMT), a marker of subclinical atherosclerosis, is higher in women with PCOS compared with women without PCOS. METHODS Primary articles reporting the mean CIMT in women with PCOS and controls were identified using Ovid MEDLINE, EMBASE and PUBMED. We performed a random-effects meta-analysis and created forest plots of the mean difference in CIMT and conducted tests for heterogeneity and publication bias. Studies were grouped by quality, defined by reporting reproducibility of CIMT and averaging both common carotid arteries versus one side for CIMT. RESULTS From the 36 eligible full-text studies, 8 studies were included in the systematic review and 19 studies were included in the meta-analysis (total n= 1123 women with PCOS, n= 923 controls). The summary mean difference in CIMT among women with PCOS compared with controls was 0.072 mm [95% confidence interval (CI) 0.040, 0.105, P < 0.0001] for highest quality studies, 0.084 mm (95% CI 0.042, 0.126, P = 0.0001) for good quality studies, 0.041 (95% CI −0.038, 0.120, P = 0.310) for fair-quality studies and 0.045 (95% CI −0.020, 0.111, P = 0.173) for lower quality studies. CONCLUSIONS Larger studies with a well-defined PCOS population using rigorous methodology may be required to draw a more robust conclusion. However, these results suggest women with PCOS are at a greater risk of premature atherosclerosis, which emphasizes the importance of screening and monitoring CVD risk factors in women with PCOS.

    Background. Women with polycystic ovary syndrome (PCOS) could develop subclinical atherosclerosis during life. Purpose. To analyze cardiovascular risk (CVR) factors and their relation to clinical markers of cardiovascular disease (CVD) in respect to their age. Material and Methods. One hundred women with PCOS (26.32 ± 5.26 years, BMI: 24.98 ± 6.38 kg/m2) were compared to 50 respective controls. In all subjects, total cholesterol (TC), HDL-C, LDL-C, triglycerides, TC/HDL-C and TG/HDL-C ratios, glucose, insulin and HOMA index, waist-to-hip ratio (WHR), systolic and diastolic blood pressure (SBP and DBP, resp.), and carotid intima-media thickness (CIMT) were analyzed in respect to their age and level of androgens. Results. PCOS over 30 years had higher WHR (P = 0.008), SBP (P < 0.001), DBP (P < 0.001), TC (P = 0.028), HDL-C (P = 0.028), LDL-C (P = 0.045), triglycerides (P < 0.001), TC/HDL-C (P < 0.001), and triglycerides/HDL-C (P < 0.001) and had more prevalent hypertension and pronounced CIMT on common carotid arteries even after adjustment for BMI (P = 0.005 and 0.036, resp.). TC/HDL-C and TG/HDL-C were higher in PCOS with the highest quintile of FAI in comparison to those with lower FAI (P = 0.045 and 0.034, resp.). Conclusions. PCOS women older than 30 years irrespective of BMI have the potential for early atherosclerosis mirrored through the elevated lipids/lipid ratios and through changes in blood pressure. PMID:25878664

    Sjögren’s syndrome (SS) is characterized by hypofunction of the salivary and lacrimal glands. The salivary function is largely dependent upon the blood supply in the glands. However, the diseased states of the gland perfusion are not well understood. The arterial spin labeling (ASL) technique allows noninvasive quantitative assessment of tissue perfusion without the need for contrast agent. Here, we prospectively compared the perfusion properties of the parotid glands between patients with SS and those with healthy glands using ASL MR imaging. We analyzed salivary blood flow (SBF) kinetics of 22 healthy parotid glands from 11 volunteers and 28 parotid glands from 14 SS patients using 3T pseudo-continuous ASL imaging. SBF was determined in resting state (base SBF) and at 3 sequential segments after gustatory stimulation. SBF kinetic profiles were characterized by base SBF level, increment ratio at the SBF peak, and the differences in segments where the peak appeared (SBF types). Base SBFs of the SS glands were significantly higher than those of healthy glands (59.2 ± 22.8 vs. 46.3 ± 9.0 mL/min/100 g, p = 0.01). SBF kinetic profiles of the SS glands also exhibited significantly later SBF peaks (p < 0.001) and higher SBF increment ratios (74 ± 49% vs. 47 ± 39%, p = 0.04) than the healthy glands. The best SBF criterion (= 51.2 mL/min/100 mg) differentiated between control subjects and SS patients with 71% sensitivity and 82% specificity. Taken together, these results showed that the SS parotid glands were mostly hyperemic and the SS gland responses to gustatory stimulation were stronger and more prolonged than those of the healthy glands. The ASL may be a promising technique for assessing the diseased salivary gland vascularization of SS patients. PMID:26959680

    Renal complications are rare in patients with Prader-Willi syndrome (PWS). We herein experienced a 31-year-old woman with PWS, in whom a renal biopsy showed IgA nephropathy and severe intimal thickening of the interlobular arteries. The patient was admitted to our hospital due to proteinuria and microscopic hematuria after an upper respiratory infection. The occurrence of cardiovascular events has been reported as a cause of death in obese PWS patients. Because chronic kidney disease is generally a risk factor for cardiovascular disease, early detection checkups are essential in obese PWS patients to monitor the possible development of cardiovascular disease.

    Symptoms of chronic mesenteric ischemia develop when the celiac artery is constricted by the median arcuate ligament of the diaphragm. Lateral aortography is the primary modality for diagnosing ligamentous compression of the celiac artery. However, duplex Doppler sonography performed during deep expiration can cause a marked increase in flow velocities at the compressed region of the celiac artery and suggest the diagnosis of celiac arterial constriction due to the diaphragmatic ligament.

    Wellens’ syndrome, also known as LAD coronary T-wave syndrome or the ‘widow maker’, is a pre-infarction syndrome with non-classical ischemic ECG changes and unremarkable cardiac biomarkers. This syndrome continues to be a ‘can't miss’ for the clinician as delay in urgent angiography and intervention can result in anterior myocardial infarction, left ventricular dysfunction, arrhythmias, and death. We describe a case followed by a discussion of identification criteria and clinical implications. PMID:26486122

    Loss of long-term projection is the major disadvantage of nipple reconstruction using local flaps. We report a technique of immediate perforator flap nipple reconstruction in breast reconstruction by latissimus dorsi (LD) myocutaneous flap in patients with Poland's syndrome. From March 2007 to July 2012, 12 female patients (age range, 15-21 years) underwent breast reconstructions and immediate nipple reconstructions. A thoracodorsal artery perforator (TAP) flap was simultaneously raised on the LD muscle flap and folded by itself to form the nipple. Both the LD flap and TAP flaps survived postoperatively. The nipple projection was measured by a caliper, and the average loss was 29% by the 1-year follow-up. Eleven patients considered the aesthetic appearance of reconstructed breast and nipple to be very good or good. The immediate nipple reconstruction with TAP flap could be safely performed and results in considerable satisfaction in breast reconstruction by LD myocutaneous flap in patients with Poland's syndrome.

    We describe a small, term, male infant with corticospinal tract aplasia secondary to motor cortex dysplasia from a neuronal proliferation and/or migrational defect. The infant also had microdolichocephaly, sloping forehead, hypertelorism, flat nose, apparently low-set ears, micrognathia, arthrogryposis without muscle wasting, cortical thumbs, rocker-bottom feet, scoliosis, single umbilical artery, and hypospadias with chordee. Oligohydramnios was present prenatally. Neurologic examination showed a comatose state, seizures, minimal spontaneous movement, minimal response to pain, and absent primitive reflexes. At autopsy, hypoplasia of kidneys and adrenal glands was found. There was no aqueductal stenosis or pulmonary hypoplasia. Chromosomes were apparently normal. These manifestations do not correspond to those of any recognized syndrome; therefore, this patient may represent a previously undefined syndrome. PMID:9286455

    The aim of this systematic review was to summarize the evidence about the risks of spinal manipulation. Articles were located through searching three electronic databases (MEDLINE, EMBASE, Cochrane Library), contacting experts (n =9), scanning reference lists of relevant articles, and searching departmental files. Reports in any language containing data relating to risks associated with spinal manipulation were included, irrespective of the profession of the therapist. Where available, systematic reviews were used as the basis of this article. All papers were evaluated independently by the authors. Data from prospective studies suggest that minor, transient adverse events occur in approximately half of all patients receiving spinal manipulation. The most common serious adverse events are vertebrobasilar accidents, disk herniation, and cauda equina syndrome. Estimates of the incidence of serious complications range from 1 per 2 million manipulations to 1 per 400,000. Given the popularity of spinal manipulation, its safety requires rigorous investigation.

    The response of the primary care physician in the initial assessment and management of acute arterial injuries will often be the deciding factor in survival of life, limb or organ system. Most arterial emergencies occur as a result of trauma, disruption of vessel wall and/or occlusion of flow. The common clinical syndromes of acute arterial emergencies are injuries to and beyond the aorta, acute aortic dissection, ruptured aortic aneurysm, and thromboembolic occlusive arterial disease. The role of arteriography and the urgency of definitive surgical repair in acute arterial emergencies is summarized. PMID:21283323

  20. Spinal anaesthesia for spinal surgery.

    PubMed

    Jellish, W Scott; Shea, John F

    2003-09-01

    Spinal anaesthesia for spinal surgery is becoming increasingly more popular because this anaesthetic technique allows the patient to self-position and avoid neurological injury that may occur with prone positioning under general anaesthesia. Spinal anaesthesia reduces intraoperative surgical blood loss, improves perioperative haemodynamic stability and reduces pain in the immediate postoperative period. This leads to a reduced need for analgesics and a reduction in the incidence of nausea and vomiting in the postoperative setting. Spinal anaesthesia for lumbar spine surgery also decreases the incidence of lower extremity thrombo-embolic complications and does not increase the occurrence of problems with micturition. These benefits increase the patient's satisfaction, and they expedite discharge of the patient from the hospital. Combination anaesthetic techniques, using both subarachnoid and epidural dosing schemes, may be beneficial for improving postoperative pain control and add further to the benefit of spinal anaesthesia for lumbar spine surgical procedures.

    When the intercostal and lumbar arteries are occluded by plaque or thrombus, spinal cord perfusion depends on collateral circulation. Some reports have demonstrated collateral circulation to the artery of Adamkiewicz via computed tomography and magnetic resonance angiographies. However, intraspinal collateral circulation to the artery of Adamkiewicz along the spinal cord has not been reported previously. Here, we report two patients with intraspinal collateral circulation to the artery of Adamkiewicz along the spinal cord that was detected with intra-arterial injected computed tomography angiography.

    Aims The aim was to study the prognostic value of plasma ceramides (Cer) as cardiovascular death (CV death) markers in three independent coronary artery disease (CAD) cohorts. Methods and results Corogene study is a prospective Finnish cohort including stable CAD patients (n = 160). Multiple lipid biomarkers and C-reactive protein were measured in addition to plasma Cer(d18:1/16:0), Cer(d18:1/18:0), Cer(d18:1/24:0), and Cer(d18:1/24:1). Subsequently, the association between high-risk ceramides and CV mortality was investigated in the prospective Special Program University Medicine—Inflammation in Acute Coronary Syndromes (SPUM-ACS) cohort (n = 1637), conducted in four Swiss university hospitals. Finally, the results were validated in Bergen Coronary Angiography Cohort (BECAC), a prospective Norwegian cohort study of stable CAD patients. Ceramides, especially when used in ratios, were significantly associated with CV death in all studies, independent of other lipid markers and C-reactive protein. Adjusted odds ratios per standard deviation for the Cer(d18:1/16:0)/Cer(d18:1/24:0) ratio were 4.49 (95% CI, 2.24–8.98), 1.64 (1.29–2.08), and 1.77 (1.41–2.23) in the Corogene, SPUM-ACS, and BECAC studies, respectively. The Cer(d18:1/16:0)/Cer(d18:1/24:0) ratio improved the predictive value of the GRACE score (net reclassification improvement, NRI = 0.17 and ΔAUC = 0.09) in ACS and the predictive value of the Marschner score in stable CAD (NRI = 0.15 and ΔAUC = 0.02). Conclusions Distinct plasma ceramide ratios are significant predictors of CV death both in patients with stable CAD and ACS, over and above currently used lipid markers. This may improve the identification of high-risk patients in need of more aggressive therapeutic interventions. PMID:27125947

    Background Despite the proven benefits of clopidogrel combined aspirin therapy for coronary artery disease (CAD), CAD patients with metabolic syndrome (MS) still tend to have coronary thrombotic events. We aimed to investigate the influence of metabolic risk factors on the efficacy of clopidogrel treatment in patients with CAD undergoing percutaneous coronary intervention (PCI). Methods Cohorts of 168 MS and 168 non-MS subjects with CAD identified by coronary angiography (CAG) were enrolled in our study. MS was defined by modified Adult Treatment Panel III criteria. All subjects had taken 100 mg aspirin and 75 mg clopidogrel daily for more than 1 month, and administered loading doses of 600 mg clopidogrel and 300 mg aspirin before PCI. Blood samples were taken 24 h after the loading doses of clopidogrel and aspirin. Platelet aggregation was measured using light transmittance aggregometry (LTA) and thrombelastography (TEG). Clopidogrel resistance was defined as more than 50% adenosine diphosphate (ADP) induced platelet aggregation as measured by TEG. Results Platelet aggregation inhibition rate by ADP was significantly lower in patients with MS as measured both by TEG (55% ± 31% vs. 68% ± 32%; P < 0.001) and LTA (29% ± 23% vs. 42% ± 29%; P < 0.001). In the multivariate analysis, elderly [OR (95% CI): 1.483 (1.047–6.248); P = 0.002], obesity [OR (95% CI): 3.608 (1.241–10.488); P = 0.018], high fasting plasma glucose level [OR (95% CI): 2.717 (1.176–6.277); P = 0.019] and hyperuricemia [OR (95% CI): 2.583 (1.095–6.094); P = 0.030] were all statistically risk factors for clopidogrel resistance. CAD patients with diabetes and obesity were more likely to have clopidogrel resistance than the CAD patients without diabetes and obesity [75% (61/81) vs. 43% (67/156); P < 0.001]. Conclusions CAD patients with MS appeared to have poorer antiplatelet response to clopidogrel compared to those without MS. Obesity, diabetes and hyperuricemia were all significantly

    Classical Hutchinson-Gilford progeria syndrome (HGPS) is caused by LMNA mutations that generate an alternatively spliced form of lamin A, termed progerin. HGPS patients present in early childhood with atherosclerosis and striking features of accelerated aging. We report on two pedigrees of adult-onset coronary artery disease with progeroid features, who were referred to our International Registry of Werner Syndrome (WS) because of clinical features consistent with the diagnosis. No mutations were identified in the WRN gene that is responsible for WS, among these patients. Instead, we found two novel heterozygous mutations at the junction of exon 10 and intron 11 of the LMNA gene. These mutations resulted in the production of progerin at a level substantially lower than that of HGPS. Our findings indicate that LMNA mutations may result in coronary artery disease presenting in the fourth to sixth decades along with short stature and a progeroid appearance resembling WS. The absence of early-onset cataracts in this setting should suggest the diagnosis of progeroid laminopathy. This study illustrates the evolving genotype-phenotype relationship between the amount of progerin produced and the age of onset among the spectrum of restrictive dermopathy, HGPS, and atypical forms of WS.

    Spinal cord infarction, especially anterior spinal artery syndrome, is a relatively rare disease. We report a case of spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus. A 52-year-old man presented with sudden onset paraplegia. At first, he was diagnosed with cervical myelopathy due to a C6-7 herniated intervertebral disc, and had an operation for C6-7 discetomy and anterior interbody fusion. Approximately 1 month after the operation, he was transferred to the department of rehabilitation in our hospital. Thoracoabdominal aortic aneurysm with intraluminal thrombus was found incidentally on an enhanced computed tomography scan, and high signal intensities were detected at the anterior horns of gray matter from the T8 to cauda equina level on T2-weighted magnetic resonance imaging. There was no evidence of aortic rupture, dissection, or complete occlusion of the aorta. We diagnosed his case as a spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus. PMID:22639759

    Abstract Metabolic syndrome (MS), high-sensitivity C-reactive protein (hs-CRP), and chronic kidney disease (CKD) are related to cardiovascular diseases. Although MS is common in CKD subjects, the contribution of MS-associated risk factors and hs-CRP to arterial stiffness in CKD has not been well studied. In this cross-sectional cohort study, we enrolled 9903 subjects who underwent brachial-ankle pulse wave velocity (baPWV) measurements from our database of Health Care Center. CKD was defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2. Comparing those grouped with and without CKD, multivariate linear regression analyses were used. Overall, baPWV was found to have an inverse relationship with eGFR (P for trend <0.001), which increased progressively with the presence of CKD, increasing number of MS-associated risk factors and hs-CRP (P for trend <0.001). In the non-CKD group, age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting glucose, triglyceride, high-density lipoprotein cholesterol, and hs-CRP independently predicted baPWV, whereas in CKD, eGFR, age, gender, body mass index, SBP, DBP, and fasting glucose remained predictors. The number of MS-associated risk factors and hs-CRP remains a determinant of arterial stiffness in both CKD and non-CKD groups. The decline of renal function contributes to arterial stiffness only in CKD but not in non-CKD. Our findings suggest that for CKD subjects, renal function, BP, and glycemic control are potential targets for further interventional studies of arterial stiffness. PMID:26356694

    Narrowing of the spinal canal or foramina is a common finding in spine imaging of the elderly. Only when symptoms of neurogenic claudication and/or cervical myelopathy are present is a spinal stenosis diagnosis made, either of the lumbar spine, cervical spine or both (only very rarely is the thoracic spine involved). Epidemiological data suggest an incidence of 1 case per 100 000 for cervical spine stenosis and 5 cases per 100 000 for lumbar spine stenosis. Cervical myelopathy in patients over 50 years of age is most commonly due to cervical spine stenosis. Symptomatic spinal narrowing can be congenital, or, more frequently, acquired. The latter may be the result of systemic illneses, namely endocrinopathies (such as Cushing disease or acromegaly), calcium metabolism disorders (including hyporarthyroidism and Paget disease), inflammatory diseases (such as rheumathoid arthritis) and infectious diseases. Physical examination is more often abnormal in cervical spondylotic myeloptahy whereas in lumbar spinal stenosis it is typically normal. Therefore spinal stenosis diagnosis relies on the clinical picture corresponding to conspicuous causative changes identified by imaging techniques, most importantly CT and MRI. Other ancillary diagnostic tests are more likely to be yielding for establishing a differential diagnosis, namely vascular claudication. Most patients have a progressive presentation and are offered non operative management as first treatment strategy. Surgery is indicated for progressive intolerable symptoms or, more rarely, for the neurologically catastrophic initial presentations. Surgical strategy consists mainly of decompression (depending on the anatomical level and type of narrowing: laminectomy, foraminotomy, discectomy, corporectomy) with additional instrumentation should spinal stability and sagittal balance be at risk. For cervical spine stenosis the main objective of surgery is to halt disease progression. There is class 1b evidence that surgery

    Neonates with respiratory distress syndrome (RDS), who are treated according to INSURE protocol; require arterial blood gas (ABG) analysis to decide on appropriate management. We conducted this study to investigate the validity of pulse oximetry instead of frequent ABG analysis in the evaluation of these patients. From a total of 193 blood samples obtained from 30 neonates <1500 grams with RDS, 7.2% were found to have one or more of the followings: acidosis, hypercapnia, or hypoxemia. We found that pulse oximetry in the detection of hyperoxemia had a good validity to appropriately manage patients without blood gas analysis. However, the validity of pulse oximetry was not good enough to detect acidosis, hypercapnia, and hypoxemia. PMID:25999627

    Clinical manifestations of empty sella syndrome include hypopituitarism cerebrospinal fluid rhinorrhea, headache, and visual abnormalities. A 21-year-old woman reported a 6-month history of worsening vision 3 years after decompression of a sellar-suprasellar Rathke cleft cyst. Her magnetic resonance imaging (MRI) showed a well-defined recurrent cyst in the sellar-suprasellar region causing chiasmatic compression. She underwent an endonasal, endoscopic decompression of the cyst, with subsequent improvement in her vision. A postoperative computed tomography confirmed good decompression of the cyst. Ten days after surgery, she reported sudden loss of vision in both eyes. MRI revealed an empty sella with herniation of both anterior cerebral arteries and optic chiasm into the sella. She underwent transnasal packing of the sellar floor with fat graft and bone plaques, and experienced gradual improvement in vision in her right eye. PMID:26828843

    Introduction Uric acid has antioxidant activity and it is expected to protect against coronary artery disease (CAD). Contradictory, it is a component of metabolic syndrome and so a risk factor for CAD. The associations of plasma total antioxidant capacity (TAOC) and uric acid (UA) as well as other risk factors were investigated relative to the occurrence and severity of CAD. Materials and Methods The study population consisted of 148 males and 152 females aged 35-76 years who were classified as CAD cases and controls according to the results of coronary angiography. The severity of CAD was scored on the basis of the number and the extent of lesions at coronary arteries. The concentrations of UA and TAOC were measured by using of FRAP and enzymatic uricase methods. Results The prevalence of hypertension, cigarette smoking and diabetes mellitus was more frequent in CAD cases than controls. Patients with CAD when compared with the controls had increased levels of glucose, triglycerides, creatinine, UA, TAOC and decreased levels of HDL- cholesterol. Serum UA was high positive correlate of serum total and LDL-cholesterol, triglyceride, creatinine, BUN, bilirubin, TAOC and negative correlate of glucose and HDL-C. TAOC and its major determinant UA but not bilirubin and albumin are significantly associated with the prevalence and severity of CAD. In multivariate analysis and in the absence of hypertension, UA but not TAOC would remain and be associated with CAD by the OR of 1.57 (1.07-2.29), p=0.02. If the results adjusted for all major risk factors including hypertension, neither TAOC nor UA would remain in the regression equation. Conclusion The results suggest that TAOC and UA but not bilirubin and albumin are associated with CAD significantly. But, the correlation is not independent and is attributed to the metabolic syndrome. The measurement of UA and TAOC will not improve the prognostic power beyond the classical risk factors.

However, the effect of rapeseed oil on the markers of subclinical atherosclerosis is not known. The purpose of this study was to compare the effects of dietary intake of cold-pressed turnip rapeseed oil (CPTRO) and butter on serum lipids, oxidized LDL and arterial elasticity in men with metabolic syndrome. Methods Thirty-seven men with metabolic syndrome completed an open and balanced crossover study. Treatment periods lasted for 6 to 8 weeks and they were separated from each other with an eight-week washout period. Subjects maintained their normal dietary habits and physical activity without major variations. The daily fat adjunct consisted either of 37.5 grams of butter or 35 mL of VirginoR CPTRO. Participants were asked to spread butter on bread on the butter period and to drink CPTRO on the oil period. The fat adjunct was used as such without heating or frying. Results Compared to butter, administration of CPTRO was followed by a reduction of total cholesterol by 8% (p < 0.001) and LDL cholesterol by 11% (p < 0.001). The level of oxidized LDL was 16% lower after oil period (p = 0.024). Minimal differences in arterial elasticity were not statistically significant. Conclusion Cold-pressed turnip rapeseed oil had favourable effects on circulating LDL cholesterol and oxidized LDL, which may be important in the management of patients at high cardiovascular risk.

    Total knee replacement (TKR) is an effective and safe procedure. However, large-scale study to compare the incidence of coronary artery disease (CAD) after spinal or epidural anesthesia (SA-EA) or general anesthesia (GA) for TKR has not ever been conducted. To do so, we studied a population-based dataset from the Taiwan National Health Research Institute and hypothesized that the incidence of CAD might be different with regional than with general anesthesia. The risk of CAD-related events during a 90-day follow-up period among patients who received TKR under SA-EA or GA was evaluated in the present study. A total of 1500 patients from the Taiwan National Health Insurance claims database who underwent TKR from January 1, 2004, to December 31, 2006, were allocated into two groups. Group 1 included 1012 patients who received SA-EA during TKR procedure. Group 2 included 488 patients who received GA during this procedure. The number of patients who developed CAD during the 90-day follow-up period was 31 (3.1 %) in group 1 and 6 (1.2 %) in group 2. The Kaplan-Meier survival analysis of IHD-free cumulative survival rate during the 90-day follow-up period for patients who underwent TKR was significantly lower in group 1 than in group 2. The hazard ratio for the occurrence of CAD was 2.80 (95 % CI 1.16-6.78), and the hazard was higher for patients who received SA-EA than for patients who received GA after adjusted potential confounding factors. After the performance of TKR, patients had a potentially increased risk for CAD in SA-EA compared to GA during the 90-day follow-up period. PMID:25761988

    Both sensorimotor and autonomic dysfunctions often occur after spinal cord injury (SCI). Particularly, a high thoracic or cervical SCI interrupts supraspinal vasomotor pathways and results in disordered hemodynamics due to deregulated sympathetic outflow. As a result of the reduced sympathetic activity, patients with SCI may experience hypotension, cardiac dysrhythmias, and hypothermia post-injury. In the chronic phase, changes within the CNS and blood vessels lead to orthostatic hypotension and life-threatening autonomic dysreflexia (AD). AD is characterized by an episodic, massive sympathetic discharge that causes severe hypertension associated with bradycardia. The syndrome is often triggered by unpleasant visceral or sensory stimuli below the injury level. Currently the only treatments are palliative – once a stimulus elicits AD, pharmacological vasodilators are administered to help reduce the spike in arterial blood pressure. However, a more effective means would be to mitigate AD development by attenuating contributing mechanisms, such as the reorganization of intraspinal circuits below the level of injury. A better understanding of the neuropathophysiology underlying cardiovascular dysfunction after SCI is essential to better develop novel therapeutic approaches to restore hemodynamic performance.

    This case report describes the diagnosis and management of a 43-year-old female patient who had sustained an injury to her neck in a motor-vehicle accident two years earlier. The major symptoms described by the patient included headache and neck pain, but history and examination also revealed signs and symptoms potentially indicative of cervical artery compromise. Physical therapy management initially consisted of soft tissue and non-thrust joint manipulation of the lower cervical and thoracic spine, specific exercise prescription, and superficial heat. Cervical vascular compromise was re-evaluated by way of the sustained extension-rotation test. When at the fifth visit this test no longer produced symptoms potentially indicative of vascular compromise, upper cervical diagnosis and management consisting of soft tissue and non-thrust joint manipulation was added. A positive outcome was achieved both at the impairment level and with regard to limitations in activities, the latter including increased performance at work, a return to previous reading activities, improved length and quality of sleep, and greater comfort while driving. At discharge, the patient reported only occasional pain and mild limitations in activities. This report describes the positive outcomes in a patient with chronic whiplash syndrome; however, its main emphasis lies in the discussion and critical evaluation of clinical reasoning in the presence of diagnostic uncertainty with regard to cervical artery compromise.

    Mice are used frequently as experimental models in the study of ischemic spinal cord injury. The aim of the present study was to describe the arterial blood supply to the thoracolumbar spinal cord in the mouse. The study was carried out on 20 adult mice using the corrosion and dissection technique. Dorsal intercostal arteries were found as branches of the thoracic aorta: as 7 pairs in 80% of cases, as 8 pairs in 15% of cases and as 9 pairs in 5% of cases. The paired lumbar arteries arising from the abdominal aorta were present as 5 pairs in all cases. Along the entire thoracic and lumbar spinal regions, we observed left-sided branches entering the ventral spinal artery in 64.2% and right-sided branches in 35.8% of cases. Along the entire thoracic and lumbar spinal regions, the branches entering the dorsal spinal arteries were left-sided in 60.8% of cases and right-sided in 39.2% of cases. We found some variations in the site of origin of the artery of Adamkiewicz and in the number of dorsal spinal arteries. Documenting the anatomical variations in spinal cord blood supply in the laboratory mouse will aid the planning of future experimental studies and in determining the clinical relevance of such studies.

    Noonan syndrome (NS) is the second most frequent hereditary syndrome with cardiac involvement. Pulmonary valve stenosis and hypertrophic cardiomyopathy are the most prevalent cardiovascular abnormalities. We report on a 14-year-old girl with NS due to SOS1 mutation with pulmonary stenosis and idiopathic coronary ectasia. To the best of our knowledge, this is the first report describing coronary ectasia in a patient with NS secondary to a SOS1 mutation. We include a literature review of this rare association.

    Summary This study includes 20 patients with 21 spinal perimedullary fistulae. There were nine Type IVa (42.8%) lesions, ten Type IVb (47.6%) and two Type IVc (9.5%) lesions. The dominant arterial supply was from the anterior spinal artery (47.6%), posterior spinal artery (19%) and directly from the radiculomedullary artery (28.5%). Sixteen lesions in 15 patients were treated by endovascular route using n-butyl-2-cyanoacrylate. Endovascular treatment was not feasible in five patients. Of the ten patients with microfistulae, catheterization failed/was not attempted in 40%, complete obliteration of the lesion was seen in 60% but clinical improvement was seen in 40% of patients. Catheterization was feasible in all ten patients with macrofistulae (nine type IVb and two type IVc lesions). Complete obliteration of the lesions was seen in 60% and residue in 30%. Clinical improvement was seen in 80% and clinical deterioration in 10%. In conclusion, endovascular glue embolization is safe and efficacious in type IVb and IVc spinal perimedullary fistulae and should be considered the first option of treatment. It is also feasible in many of the type IVa lesions. PMID:24976100

    Kounis syndrome is characterised by a group of symptoms that manifest as unstable vasospastic or non-vasospastic angina secondary to a hypersensitivity reaction. It was first described by Kounis and Zavras in 1991 as the concurrence of an allergic response with an anaphylactoid or anaphylactic reaction and coronary artery spasm or even myocardial infarction. Since then, this condition has evolved to include a number of mast cell activation disorders associated with acute coronary syndrome. There are many triggering factors, including reactions to multiple medications, exposure to radiological contrast media, poison ivy, bee stings, shellfish and coronary stents. In addition to coronary arterial involvement, Kounis syndrome comprises other arterial systems with similar physiologies, such as mesenteric and cerebral circulation resulting in ischaemia/infarction of the vital organs. The incidence of this condition is difficult to establish owing to the number of potential instigating factors and its relatively infrequent documentation in the literature.We report the case of an HIV-negative 39-year-old man with no coronary risk factors or family history of premature coronary artery disease, who developed Kounis syndrome after the administration of fluoroquinolone for dysuria. However, to the best of our knowledge,no data on the incidence and prevalence of Kounis syndrome in South Africa have ever been reported in the literature. The recent understanding of Kounis syndrome has led to the condition being classified into three syndrome variants. PMID:26636160

    Although osteosarcoma represents the second most common primary bone tumor, spinal involvement is rare, accounting for 3%–5% of all osteosarcomas. The most frequent symptom of osteosarcoma is pain, which appears in almost all patients, whereas more than 70% exhibit neurologic deficit. At a molecular level, it is a tumor of great genetic complexity and several genetic disorders have been associated with its appearance. Early diagnosis and careful surgical staging are the most important factors in accomplishing sufficient management. Even though overall prognosis remains poor, en-block tumor removal combined with adjuvant radiotherapy and chemotherapy is currently the treatment of choice. This paper outlines histopathological classification, epidemiology, diagnostic procedures, and current concepts of management of spinal osteosarcoma. PMID:24179411

    Vascular corrosion casts of polyester resin in the normal spinal cord at C4-C6 and C7-T1 were inspected three-dimensionally by scanning electron microscopy in 13 rats. Arteries and veins were easily differentiated by the impression pattern of endothelial nuclei on the casts. The centrifugal arterial system from the sulcal arteries supplied most of the gray and white matter in the ventral and lateral spinal cord. Each sulcal artery supplied only one side of the cord. The average number of sulcal arteries was 2.6 per mm. The centripetal arterial system from the posterior spinal arteries fed the posterior gray and white matter. In contrast with classical concepts, there was no pial arterial plexus on the ventral and ventrolateral surface except for infrequent transverse branches from the anterior spinal artery. In the posterior columns, two types of large veins were identified: the posterior medial septal veins and the posterior oblique veins that drained the posterior columns, medial posterior gray matter, and posterior gray commissure. The remainder of the gray and white matter was drained by the sulcal veins and the radial veins. This method clearly demonstrates the three-dimensional structure of both the arterial and venous system in the rat spinal cord. PMID:8367051

    In the case of non-ST-segment elevation acute coronary syndromes (NSTE-ACSs), the acute use of certain antiplatelet agents is complicated by concerns about perioperative bleeding risks in patients requiring coronary artery bypass grafting (CABG) during the index hospitalization. As a result, clinicians often withhold potentially useful agents, such as clopidogrel, before determining patients' coronary anatomy. An accurate predictive model could allow for a better balance of this safety concern with the demonstrated benefits of agents such as clopidogrel. To create an accurate decision-making tool that would assess, at hospital presentation, the need for CABG in patients with NSTE-ACSs, we studied 61,974 high-risk patients with NSTE-ACS admitted to 311 CABG-capable hospitals participating in Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes With Early Implementation of the American College of Cardiology/American Heart Association Guidelines (CRUSADE) from 2001 to 2003. A total of 8,395 patients (14%) underwent CABG during their initial hospital stay. A multivariate model was developed and identified 13 presenting clinical characteristics significantly associated with the likelihood of CABG (previous CABG, male gender, previous heart failure, diabetes, hyperlipidemia, renal insufficiency, ST depression and transient ST elevation, age > or = 75 years, previous percutaneous coronary intervention, family history of coronary artery disease, hypertension, trends in CABG rates, and previous stroke). This model had only modest predictive accuracy and calibration (c-index = 0.67). In conclusion, although certain presenting clinical features are associated with an increased likelihood of CABG in patients with NSTE-ACSs during the index hospitalization, it remains difficult to reliably identify, before diagnostic angiography, those who will subsequently undergo surgical revascularization.

  17. Metabolic syndrome and dietary components are associated with coronary artery disease risk score in free-living adults: a cross-sectional study

    PubMed Central

    2011-01-01

    Background Coronary artery disease (CAD) is among the main causes of death in developed countries, and diet and lifestyle can influence CAD incidence. Objective To evaluate the association of coronary artery disease risk score with dietary, anthropometric and biochemical components in adults clinically selected for a lifestyle modification program. Methods 362 adults (96 men, 266 women, 53.9 ± 9.4 years) fulfilled the inclusion criteria by presenting all the required data. The Framingham score was calculated and the IV Brazilian Guideline on Dyslipidemia and Prevention of Atherosclerosis was adopted for classification of the CAD risks. Anthropometric assessments included waist circumference (WC), body fat and calculated BMI (kg/m2) and muscle-mass index (MMI kg/m2). Dietary intake was estimated through 24 h dietary recall. Fasting blood was used for biochemical analysis. Metabolic Syndrome (MS) was diagnosed using NCEP-ATPIII (2001) criteria. Logistic regression was used to determine the odds of CAD risks according to the altered components of MS, dietary, anthropometric, and biochemical components. Results For a sample with a BMI 28.5 ± 5.0 kg/m2 the association with lower risk (<10% CAD) were lower age (<60 years old), and plasma values of uric acid. The presence of MS within low, intermediary, and high CAD risk categories was 30.8%, 55.5%, and 69.8%, respectively. The independent risk factors associated with CAD risk score was MS and uric acid, and the protective factors were recommended intake of saturated fat and fiber and muscle mass index. Conclusion Recommended intake of saturated fat and dietary fiber, together with proper muscle mass, are inversely associated with CAD risk score. On the other hand, the presence of MS and high plasma uric acid are associated with CAD risk score. PMID:21554698

    Spinal cord injuries frequently determine central pain symptoms that are difficult to control. The authors present the case of a 67-year-old suffering from a pleural mesothelioma. During the disease course, he developed a paraplegia syndrome from mesothelioma compression of the spinal cord at T4-T5 level. Following spinal decompression surgery, the patient presented an intense at-level, superficial neuropathic pain syndrome with allodynia and hyperalgesia. After systemic pharmacological therapies had failed, treatment with lidocaine 5% plaster was initiated. The superficial neuropathic symptoms almost completely disappeared within a few days. The lidocaine topical treatment was continued for months with durable analgesic effect. PMID:27018847

    The clinical and laboratory findings in six patients with congenital narrowing of the cervical spinal canal and neurological symptoms are described. A variable age of onset and an entirely male occurrence were found. Signs and symptoms of spinal cord dysfunction predominated in all but one patient. Symptoms were produced in five patients by increased physical activity alone. Congenital narrowing of the cervical spinal canal may result in cord compression without a history of injury and occasionally without evidence of significant bony degenerative changes. The clinical features may be distinguishable from those found in cervical spondylosis without congenital narrowing. Intermittent claudication of the cervical spinal cord appears to be an important feature of this syndrome. Surgery improved four out of five people. PMID:1219087

    In this case-based review, the authors analyzed relevant literature with an illustrative patient of theirs about subdural hematoma secondary to dural tear at spinal surgery. Intracranial hypotension is a condition of decreased cerebrospinal fluid volume and pressure. Even though intracranial hypotension is temporary and can be managed conservatively, it may progress and result in subdural fluid collections, hematoma formations, "brain sagging or slumping" states, syringohydromyelia, encephalopathy, coma, and even death. The authors present an 81-year-old man admitted with subdural hematoma 50 days following previous spinal surgery for lumbar spinal stenosis. In his previous spinal surgery he had had dural tear, which had been closed primarily. To the literature, only 21 patients have been reported to develop subdural hematoma following spinal surgery. In patients with subdural hematoma following spinal surgery, the female:male ratio was 3:4 and the median age was 55 years. Surgical diagnoses for previous spinal surgeries were intervertebral disc herniation (5), spinal canal stenosis and spondylolisthesis (6), failed back syndrome (2), tethered cord syndrome and myelodysplastic spine (2), spinal cord tumor, spinal epidural hematoma, vertebral dislocation, vertebral fracture, vertebral tumor, and inflammatory spine. Patients presented with signs and symptoms of subdural hematoma within 6 hours to 50 days following the spinal surgery. Source of cerebrospinal fluid leak was most commonly from lumbar region (13 patients, 62%). Ten of 21 (48%) patients were treated conservatively. Late-onset neurological findings should not prevent the evaluation of cranial vault with computed tomography and magnetic resonance imaging. Spinal dural tear should be more aggressively treated instead of suture alone approach, when recognized in older patients during the spinal surgery. PMID:27192649

    We report four children with Down Syndrome (DS) without evidence of congenital heart disease who sustained cerebral infarction in the context of an infectious disease. In one child, stroke occurred in the context of acute infection with Mycoplasma pneumonia. In another child, stroke occurred in the context of Streptococcus oralis (viridans subgroup) infection. In two other children, stroke occurred in the context of a bibasilar pneumonia for which an etiologic agent was not found. All patients had evidence of selective IgG4 subclass deficiency. We followed 8 other children with down syndrome with infectious diseases, but without stroke and a control group of healthy children, and measured the value of IgG4 for each group. We found a statistical significant difference of levels of IgG4 subclass deficiency in the group of stroke, in comparison with the other two groups (P values <0.001). We, therefore, suggest an association between IgG4 subclass deficiency and stroke in DS patients. IgG4 subclass deficiency could conceivably play a role in the high frequency of para-infectious related stroke in this population. PMID:24613243

    Administration of black raspberry (Rubus occidentalis) is known to improve vascular endothelial function in patients at a high risk for cardiovascular (CV) disease. We investigated short-term effects of black raspberry on circulating endothelial progenitor cells (EPCs) and arterial stiffness in patients with metabolic syndrome. Patients with metabolic syndrome (n = 51) were prospectively randomized into the black raspberry group (n = 26, 750 mg/day) and placebo group (n = 25) during the 12-week follow-up. Central blood pressure, augmentation index, and EPCs, such as CD34/KDR(+), CD34/CD117(+), and CD34/CD133(+), were measured at baseline and at 12-week follow-up. Radial augmentation indexes were significantly decreased in the black raspberry group compared to the placebo group (-5% ± 10% vs. 3% ± 14%, P < .05). CD34/CD133(+) cells at 12-week follow-up were significantly higher in the black raspberry group compared to the placebo group (19 ± 109/μL vs. -28 ± 57/μL, P < .05). Decreases from the baseline in interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were significantly greater in the black raspberry group compared to the placebo group (-0.5 ± 1.4 pg/mL vs. -0.1 ± 1.1 pg/mL, P < .05 and -5.4 ± 4.5 pg/mL vs. -0.8 ± 4.0 pg/mL, P < .05, respectively). Increases from the baseline in adiponectin levels (2.9 ± 2.1 μg/mL vs. -0.2 ± 2.5 μg/mL, P < .05) were significant in the black raspberry group. The use of black raspberry significantly lowered the augmentation index and increased circulating EPCs, thereby improving CV risks in patients with metabolic syndrome during the 12-week follow-up.

    Objective In women, metabolic syndrome (MetS) is associated with higher risk of ischemic heart disease-related adverse outcomes versus individual components. We examined the relationship of MetS to subclinical coronary atherosclerosis. Methods Women (n = 100) undergoing coronary angiography for suspected ischemia but without obstructive coronary artery disease (CAD) underwent intravascular ultrasound (IVUS) of a segment of the left coronary artery. A core lab, masked to other findings, assessed IVUS measures and normalized volume measures to pull-back length. MetS [defined using ATPIII criteria (fasting glucose ≥ 100 mg/dl per revised NCEP guideline)] and its components were entered into multiple regression models to assess associations with IVUS measures. Results Detailed IVUS measurements were available in 87 women. Mean age was 54 ± 10 years, 36% had MetS, and 78% had atheroma. Comparing women with MetS versus without MetS, significant differences were observed for seven IVUS atherosclerosis measures, but were not significant after adjusting for the MetS components. Systolic blood pressure and waist circumference components remained independently positively associated with the IVUS measures after adjusting for age, diabetes, CAD family history, dyslipidemia, smoking, and hormone replacement. Conclusion In women with signs and symptoms of ischemia and no obstructive CAD, MetS is associated with coronary atherosclerosis presence and severity. However, these associations appear largely driven by components of waist circumference and systolic blood pressure versus MetS cluster. This supports the concept that MetS is a convenient clustering of risk factors rather than an independent risk predictor, and emphasizes that the critical factors for coronary atherosclerosis are potentially modifiable.

    Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation).

    Vascular Ehlers-Danlos Syndrome (previously Ehlers-Danlos IV) is a rare autosomal dominant collagen vascular disorder caused by a 2q31 COL3A1 gene mutation encoding pro-alpha1 chain of type III collagen (in contrast to classic Ehlers-Danlos, caused by a COL5A1 mutation). The vascular type accounts for less than 4% of all Ehlers-Danlos cases and usually has a poor prognosis due to life threatening vascular ruptures and difficult, frequently unsuccessful surgical and vascular interventions. In 70% of cases, vascular rupture or dissection, gastrointestinal perforation, or organ rupture is a presenting sign. We present a case of genetically proven vascular Ehlers-Danlos with fatal recurrent retroperitoneal hemorrhages secondary to a ruptured right common iliac artery dissection in a 30-year-old male.

    Background The aim of the study was to investigate the presence of possible markers in the prediction of polycystic ovary syndrome (PCOS)-related metabolic alterations and cardiovascular events in adolescent PCOS cases and also to investigate the applicability of anti-Mullerian hormone (AMH) levels for the diagnosis of PCOS. Methods In this cross-sectional study, a total of 75 non-obese women (adolescent PCOS group, n = 25; adult PCOS group, n = 25; control group, n = 25) were included. Measurements of copeptin, pentraxin 3 (PTX3), and AMH serum levels were performed. Results Serum copeptin, PTX3 and echocardiographic indices were not significantly different in PCOS subjects and they did not have higher common carotid artery intima-media thickness (CIMT) measurement. AMH levels were significantly higher in PCOS patients. There was a positive correlation between AMH and mean ovarian volume (r = 0.58, P < 0.001) and between AMH and total testosterone level (r = 0.63, P < 0.001). In order to predict a threshold value for the diagnosis of PCOS by using AMH, the receiver operating characteristic (ROC) method was used. Area under the curve was 0.820 and cut-off point was 6.66 ng/mL for AMH with a sensitivity of 62% and specificity of 76%. Conclusions Possible markers for PCOS-related metabolic alterations may not present in the adolescent years. Serum AMH may be useful as a diagnostic test for adolescents. PMID:26566413

  7. False aneurysm of the interosseous artery and anterior interosseous syndrome - an unusual complication of penetrating injury of the forearm: a case report

    2009-01-01

    Background Palsies involving the anterior interosseous nerve (AIN) comprise less than 1% of all upper extremity nerve palsies. Objectives This case highlights the potential vascular and neurological hazards of minimal penetrating injury of the proximal forearm and emphasizes the phenomenon of delayed presentation of vascular injuries following seemingly obscure penetrating wounds. Case Report We report a case of a 22-year-old male admitted for a minimal penetrating trauma of the proximal forearm that, some days later, developed an anterior interosseous syndrome. A Duplex study performed immediately after the trauma was normal. Further radiologic investigations i.e. a computer-tomographic-angiography (CTA) revealed a false aneurysm of the proximal portion of the interosseous artery (IA). Endovascular management was proposed but a spontaneous rupture dictated surgical revision with simple excision. Complete neurological recovery was documented at 4 months postoperatively. Conclusions/Summary After every penetrating injury of the proximal forearm we propose routinely a detailed neurological and vascular status and a CTA if Duplex evaluation is negative. PMID:20034382

    The overall safety and efficacy of transradial coronary intervention (TRI) versus coronary artery bypass grafting (CABG) for patients with unprotected left main (UPLM) disease and/or multivessel coronary disease (MVD) presenting with acute coronary syndrome (ACS) have not been established. Consecutive patients with ACS undergoing TRI with drug-eluting stent (n = 1431) or CABG (n = 651) for UPLM and/or MVD were included. A propensity-score matching was performed to adjust for differences in baseline characteristics between the 2 cohorts, yielding 524 pairs of matched patients. Median clinical follow-up was 32 months. After propensity-score adjustment, no significant difference was observed between the TRI and CABG groups in all-cause mortality (4.0% vs 5.2%; P = .375). Transradial coronary intervention was favored by a significant increase in the incidence of stroke in the CABG group (0.4% vs 1.9%; P = .020), whereas a significantly increased target vessel revascularization rate (16.8% vs 6.3%; P < .0001) observed in the TRI group favored CABG. Composite outcome (death/myocardial infarction/stroke) was comparable between the TRI and the CABG groups (8.0% vs 11.5%; P = .061). Clinical outcomes of TRI on UPLM and/or MVD for patients with ACS are comparable to CABG in composite safety outcomes with the advantage to TRI for avoiding a stroke. PMID:25818105

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

    Spinal cord injury (SCI) can induce prolonged spinal cord compression that may result in a reduction of local tissue perfusion, progressive ischemia, and potentially irreversible tissue necrosis. Due to the combination of risk factors and the varied presentation of symptoms, the appropriate method and time course for clinical intervention following SCI are not always evident. In this study, a three-dimensional finite element fluid-structure interaction model of the cervical spinal cord was developed to examine how traditionally sub-clinical compressive mechanical loads impact spinal arterial blood flow. The spinal cord and surrounding dura mater were modeled as linear elastic, isotropic, and incompressible solids, while blood was modeled as a single-phased, incompressible Newtonian fluid. Simulation results indicate that anterior, posterior, and anteroposterior compressions of the cervical spinal cord have significantly different ischemic potentials, with prediction that the posterior component of loading elevates patient risk due to the concomitant reduction of blood flow in the arterial branches. Conversely, anterior loading compromises flow through the anterior spinal artery but minimally impacts branch flow rates. The findings of this study provide novel insight into how sub-clinical spinal cord compression could give rise to certain disease states, and suggest a need to monitor spinal artery perfusion following even mild compressive loading.

    Lumbar spinal stenosis (LSS) affects more than 200,000 adults in the United States, resulting in substantial pain and disability. It is the most common reason for spinal surgery in patients over 65 years. Lumbar spinal stenosis is a clinical syndrome of pain in the buttocks or lower extremities, with or without back pain. It is associated with reduced space available for the neural and vascular elements of the lumbar spine. The condition is often exacerbated by standing, walking, or lumbar extension and relieved by forward flexion, sitting, or recumbency. Clinical care and research into lumbar spinal stenosis is complicated by the heterogeneity of the condition, the lack of standard criteria for diagnosis and inclusion in studies, and high rates of anatomic stenosis on imaging studies in older people who are completely asymptomatic. The options for non-surgical management include drugs, physiotherapy, spinal injections, lifestyle modification, and multidisciplinary rehabilitation. However, few high quality randomized trials have looked at conservative management. A systematic review concluded that there is insufficient evidence to recommend any specific type of non-surgical treatment. Several different surgical procedures are used to treat patients who do not improve with non-operative therapies. Given that rapid deterioration is rare and that symptoms often wax and wane or gradually improve, surgery is almost always elective and considered only if sufficiently bothersome symptoms persist despite trials of less invasive interventions. Outcomes (leg pain and disability) seem to be better for surgery than for non-operative treatment, but the evidence is heterogeneous and often of limited quality. PMID:26727925

    The initial hypoxemic level of acute respiratory distress syndrome (ARDS) defined according to Berlin definition might not be the optimal predictor for prognosis. We aimed to determine the predictive validity of the stabilized ratio of partial pressure arterial oxygen and fraction of inspired oxygen (PaO2/FiO2 ratio) following standard ventilator setting in the prognosis of patients with ARDS.This prospective observational study was conducted in a single tertiary medical center in Taiwan and compared the stabilized PaO2/FiO2 ratio (Day 1) following standard ventilator settings and the PaO2/FiO2 ratio on the day patients met ARDS Berlin criteria (Day 0). Patients admitted to intensive care units and in accordance with the Berlin criteria for ARDS were collected between December 1, 2012 and May 31, 2015. Main outcome was 28-day mortality. Arterial blood gas and ventilator setting on Days 0 and 1 were obtained.A total of 238 patients met the Berlin criteria for ARDS were enrolled, and they were classified as mild (n = 50), moderate (n = 125), and severe (n = 63) ARDS, respectively. Twelve (5%) patients who originally were classified as ARDS did not continually meet the Berlin definition, and a total of 134 (56%) patients had the changes regarding the severity of ARDS from Day 0 to Day 1. The 28-day mortality rate was 49.1%, and multivariate analysis identified age, PaO2/FiO2 on Day 1, number of organ failures, and positive fluid balance within 5 days as significant risk factors of death. Moreover, the area under receiver-operating curve for mortality prediction using PaO2/FiO2 on Day 1 was significant higher than that on Day 0 (P = 0.016).PaO2/FiO2 ratio on Day 1 after applying mechanical ventilator is a better predictor of outcomes in patients with ARDS than those on Day 0.

    The purpose of this study was to investigate the relationship between alcohol consumption and the prevalence of the metabolic syndrome (MetS), type 2 diabetes mellitus (DM), coronary heart disease (CHD), stroke, peripheral arterial disease (PAD), and overall cardiovascular disease (CVD) in a Mediterranean cohort. It consisted of a cross-sectional analysis of a representative sample of Greek adults (n = 4,153) classified as never, occasional, mild, moderate, or heavy drinkers. Cases with overt CHD, stroke, or PAD were recorded. In our population, 17% were never, 23% occasional, 27% mild, 24% moderate, and 9% heavy drinkers. Moderate alcohol consumption was associated with a lower trend for the prevalence of the MetS (P = .0001), DM (P < .0001), CHD (P = .0002), PAD (P = .005), and overall CVD (P = .001) but not stroke compared with no alcohol use. Heavy drinking was associated with an increase in the prevalence of all of these disease states. Wine consumption was associated with a slightly better effect than beer or spirits consumption on the prevalence of total CVD, and beer consumption was associated with a better effect than spirits consumption. Alcohol intake was positively related with body weight, high-density lipoprotein cholesterol levels, and hypertension. Moderate alcohol consumption is associated with a lower prevalence of the MetS, DM, PAD, CHD, and overall CVD but not stroke compared with no alcohol use in a Mediterranean population. Heavy drinking was associated with an increase in the prevalence of all of these disease states. Advice on alcohol consumption should probably mainly aim at reducing heavy drinking. PMID:18216378

    Acute coronary artery syndrome (ACS) is the major cause of mortality in Pakistan with genetic and environmental influence on the incidence of the disease. This case-control study was designed to find out if a correlation is existing between ACS and single nucleotide polymorphisms (SNPs) in DNA repair genes XPD [at codon 751, rs 13181 (Lys to Gln)] and XRCC1 [at codon 399, rs25487 (Arg to Gln); 280, rs25489 (Arg to His) and 194, rs 1799782 (Arg to Trp)] either individually or in various combination with each other (haplotype analysis). The objective of this study was to find out the association of various studied risk factors and serum lipid profile of the subjects with the disease, if any. PCR-RFLP method was used to determine genotype at specific codon in 221 subjects (115 ACS patients and 106 healthy controls) from Southern Punjab population. Genotypic and allelic frequency distribution among the cases and controls revealed that all the studied SNPs were not individually associated with the ACS. Haplotype analysis revealed that subjects having wild type combination of all three XRCC1 SNPs had greater susceptibility to ACS than any other studied genotypic combinations. Analysis of risk factors revealed that hypertension (P<0.001), age (P=0.05), education (P<0.001), gender (P<0.001), family history (P=0.005), smoking habit (P=0.002) and diabetes (P<0.001) were significantly associated with the incidence of ACS. Serum lipid profile analysis indicated that cholesterol level was significantly higher (P=0.048) in patients (161.5mg/dL) than controls (142.1mg/dL) while triglyceride remained unaffected (P=0.87) when compared between the two treatments.

    Background There is considerable interest in oxygen partial pressure (Po2) monitoring in physiology, and in tracking Po2 changes dynamically when it varies rapidly. For example, arterial Po2 (PaO2) can vary within the respiratory cycle in cyclical atelectasis (CA), where PaO2 is thought to increase and decrease during inspiration and expiration, respectively. A sensor that detects these PaO2 oscillations could become a useful diagnostic tool of CA during acute respiratory distress syndrome (ARDS). Methods We developed a fibreoptic Po2 sensor (<200 µm diameter), suitable for human use, that has a fast response time, and can measure Po2 continuously in blood. By altering the inspired fraction of oxygen (FIO2) from 21 to 100% in four healthy animal models, we determined the linearity of the sensor's signal over a wide range of PaO2 values in vivo. We also hypothesized that the sensor could measure rapid intra-breath PaO2 oscillations in a large animal model of ARDS. Results In the healthy animal models, PaO2 responses to changes in FIO2 were in agreement with conventional intermittent blood-gas analysis (n=39) for a wide range of PaO2 values, from 10 to 73 kPa. In the animal lavage model of CA, the sensor detected PaO2 oscillations, also at clinically relevant PaO2 levels close to 9 kPa. Conclusions We conclude that these fibreoptic PaO2 sensors have the potential to become a diagnostic tool for CA in ARDS. PMID:25631471

    The arachidonic acid metabolites participate in development of coronary artery disease (CAD) and the plaque's instability. We assessed two common genetic polymorphisms: of cyclooxygenase-2 (COX-2) (COX2.8473, rs5275) and prostaglandin EP2 receptor gene (uS5, rs708494) in patients with CAD. Out of 1,368 patients screened by coronary arteriography, two groups fulfilled the entry criteria and were studied: stable coronary disease (sCAD, n = 125) and acute coronary syndromes (ACS, n = 63). They did not differ in the main characteristics. All patients were on aspirin at least seven days prior to the study. In 70 control subjects, the same genotypes were ascertained, expression of cyclooxygenases in peripheral blood monocytes was assessed by flow cytometry, and in-vitro biosynthesis of PGE(2) was measured by mass spectrometry. COX-2 CC homozygotes (variant allele), were more common, while EP2 GG homozygotes (wild-type) were less common in ACS (p = 0.03 and p = 0.017) than in the sCAD group. A combined genotype characterized by the presence of the wild-type COX2.8743T allele and the wild type homozygous EP2uS5 genotype (TT or CT | GG) decreased risk ratio of ACS in CAD patients (relative risk 0.41; 95% confidence interval 0.21-0.81). COX-2 polymorphism in control subjects did not affect the enzyme expression or PGE(2) production by peripheral blood monocytes, but production of PGE(2) increased by 40.1% in the subjects homozygous for EP2 receptor allele uS5A following lipopolysaccharide stimulation. In conclusion, the combined COX-2 (COX2.8473) and the EP2 receptor (uS5) genotypes seem to influence CAD stability, but in peripheral blood monocytes only EP2 receptor modulates PGE(2) production.

    Objectives To investigate the impact of arterial remodelling on long‐term clinical outcome after stent implantation in patients with acute coronary syndrome (ACS). Methods 134 patients with ACS were enrolled. External elastic membrane (EEM) cross‐sectional area (CSA) and lumen CSA were measured. Plaque and media CSA was calculated as EEM minus lumen CSA. Final minimal stent area (MSA) was also measured after stenting. Positive remodelling (PR) was defined as the ratio of the EEM CSA at the target lesion to that at the proximal reference of >1.05, and intermediate or negative remodelling (IR/NR) was defined as that of ⩽1.05. Results Although final MSA was similar, target lesion revascularisation (TLR) rates at 2 years were significantly higher in patients with PR (33.7%) than in those with IR/NR (13.7%; p = 0.01). In addition, non‐TLR rates were also significantly higher in patients with PR (42.2%) than in those with IR/NR (23.5%; p = 0.03). Cardiac event‐free survival (for events such as death, myocardial infarction, TLR and non‐TLR) was significantly lower in patients with PR than in those with IR/NR (log rank, p = 0.001). By multivariate logistic regression analysis, PR (χ2 6.57, OR 2.70; 95% CI, 1.27 to 5.78; p = 0.01) and plaque rupture (χ2 4.17, OR 2.38; 95% CI, 1.04 to 5.45; p = 0.04) were independent predictors of cardiac events. Conclusion In patients with ACS, PR and intravascular ultrasound findings that may correspond with plaque rupture predict cardiac events including both TLR and non‐TLR at 2 years. PMID:17395673

    A 25-year-old woman developed a spinal cord infarction leading to quadriplegia and respiratory insufficiency after consuming cocaine and vodka for several days. Within five months, she regained full motor and respiratory function. A literature review revealed 11 cases of cocaine-induced spinal cord infarction. A complete recovery from quadriplegia and respiratory failure following cocaine abuse has never been reported to date. The value of diffusion-weighted imaging in cocaine-induced spinal cord infarction is here presented and discussed. The literature proposes several mechanisms for cocaine-induced infarction including vasospasm, arteritis, and thrombosis. In this case, the imaging studies and the full recovery suggest that the spinal cord ischemia was secondary to a transient vasospasm of the anterior spinal artery. PMID:24028991

    Spinal arachnoiditis is an insidious disease caused by an inflammatory process of the arachnoid membrane resulting from many possible causes, such as myelograms with oil-based radiographic contract agents and multiple back surgeries. Diagnosis is based on symptoms and magnetic resonance imaging. Arachnoiditis can also mimic the symptoms of other diseases, such as spinal cord tumors, cauda equina syndrome, arachnoiditis ossificans, and syringomyelia. Unfortunately, there is no cure, only treatment of the chronic symptoms. It is an incurable disease that can cause minor to severe symptoms from unexplained rashes to neurologic defects.

    Inducible nitric oxide synthase and N-methyl-D-aspartate receptors have been shown to participate in nerve cell injury during spinal cord ischemia. This study observed a protective effect of curcumin on ischemic spinal cord injury. Models of spinal cord ischemia were established by ligating the lumbar artery from the left renal artery to the bifurcation of the abdominal aorta. At 24 hours after model establishment, the rats were intraperitoneally injected with curcumin. Reverse transcription-polymerase chain reaction and immunohistochemical results demonstrated that after spinal cord ischemia, inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression significantly increased. However, curcumin significantly decreased inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression in the ischemic spinal cord. Tarlov scale results showed that curcumin significantly improved motor function of the rat hind limb after spinal cord ischemia. The results demonstrate that curcumin exerts a neuroprotective fect against ischemic spinal cord injury by decreasing inducible nitric oxide synthase and N-methyl-D-aspartate receptor expression.

He was diagnosed with Scimitar Syndrome in the neonatal period by ultrasound, which revealed partial anomalous pulmonary venous return (PAPVR) of the right pulmonary vein to the inferior vena cava, as well as dextroversion of the heart, hypoplastic right pulmonary artery, and right lung hypoplasia. Due to the large shunt volume, the patient exhibited signs of congestive heart failure with dilatation of the left atrium and left ventricle. The patient underwent cardiac catheterization, which confirmed the presence of PAPVR as well as a large aorto-pulmonary collateral connecting the sequester to the descending aorta. Due to the high flow within the sequester artery a combined "sandwich" technique was used with two AGA vascular plugs (II) and MWCE Tornado coils. Complete closure of the collateral was achieved.

  10. How to prevent spinal cord injury during endovascular repair of thoracic aortic disease.

    PubMed

    Uchida, Naomichi

    2014-07-01

    The incidence of spinal cord injury in thoracic endovascular aortic repair (TEVAR) has been 3-5 % from recent major papers where sacrifice of the critical intercostal arteries is inevitable by a stent graft. Hemodynamic stability, which depends on a network of blood vessels around the cord is most important not only during but also after stent-graft deployment. High risk factors of spinal cord injury during endovascular aortic repair are (1) coverage of the left subclavian artery, (2) extensive coverage of long segments of the thoracic aorta, (3) prior downstream aortic repair, (4) compromising important intercostal (T8-L1), vertebral, pelvic and hypogastric collaterals, and (5) shaggy aorta. Preoperative, intraoperative, and postoperative managements have been required to prevent spinal cord injury with TEVAR. For imaging assessment of blood supply to spinal cord including Adamkiewicz artery, prophylactic cerebrospinal fluid drainage is mandatory, and monitoring motor-evoked potential is recommended for high risk factors of spinal cord injury. Mean arterial pressure should be maintained over 90 mmHg after stent-graft placement for a while to prevent delayed spinal cord ischemia in high-risk patients of spinal cord ischemia. Finally, because spinal cord injury during TEVAR is not rare and negligible, perioperative care during TEVAR should be strictly performed according to the protocol proposed by each cardiovascular team.

    Vascular pathologies of the spinal cord are rare and often overlooked. This article presents clinical and imaging approaches to the diagnosis and management of spinal vascular conditions most commonly encountered in clinical practice. Ischemia, infarction, hemorrhage, aneurysms, and vascular malformations of the spine and spinal cord are discussed. Pathophysiologic mechanisms, clinical classification schemes, clinical presentations, imaging findings, and treatment modalities are considered. Recent advances in genetic and syndromic vascular pathologies of the spinal cord are also discussed. Clinically relevant spinal vascular anatomy is reviewed in detail. PMID:27616317

  14. Complete nonsurgical resolution of a spontaneous spinal epidural hematoma.

    PubMed

    Silber, S H

    1996-07-01

    Spontaneous spinal epidural hematomas (SSEH) are heralded by spinal pain and progressive cord compression syndromes which may lead to permanent neurological disability or death if emergent neurosurgical intervention is delayed. It therefore must be considered early in the differential diagnosis of acute spinal cord compression syndrome. A case of spontaneous spinal epidural hematoma presenting as an acute myelopathy in a clarinet player who chronically used a nonsteroidal anti-inflammatory medication is presented. The case was remarkable for the rare complete spontaneous resolution of neurological function. Approximately 250 cases of SSEH have been reported in the medical literature, although only a handful of these patients have recovered spontaneously. This is the sixth report of such an event. The etiologies, contributing factors, disease progression, and treatment recommendations are discussed. PMID:8768163

    2013-01-01

    The two amino acids γ-amino butyric acid (GABA) and glycine mediate fast inhibitory neurotransmission in different CNS areas and serve pivotal roles in the spinal sensory processing. Under healthy conditions, they limit the excitability of spinal terminals of primary sensory nerve fibers and of intrinsic dorsal horn neurons through pre- and postsynaptic mechanisms, and thereby facilitate the spatial and temporal discrimination of sensory stimuli. Removal of fast inhibition not only reduces the fidelity of normal sensory processing but also provokes symptoms very much reminiscent of pathological and chronic pain syndromes. This review summarizes our knowledge of the molecular bases of spinal inhibitory neurotransmission and its organization in dorsal horn sensory circuits. Particular emphasis is placed on the role and mechanisms of spinal inhibitory malfunction in inflammatory and neuropathic chronic pain syndromes. PMID:22298656

  16. Intractable Pruritus After Traumatic Spinal Cord Injury

    PubMed Central

    Crane, Deborah A; Jaffee, Kenneth M; Kundu, Anjana

    2009-01-01

    Background: This report describes a young woman with incomplete traumatic cervical spinal cord injury and intractable pruritus involving her dorsal forearm. Method: Case report. Findings: Anatomic distribution of the pruritus corresponded to the dermatomal distribution of her level of spinal cord injury and vertebral fusion. Symptoms were attributed to the spinal cord injury and possible cervical root injury. Pruritus was refractory to all treatments, including topical lidocaine, gabapentin, transcutaneous electrical nerve stimulation, intravenous Bier block, stellate ganglion block, and acupuncture. Conclusions: Further understanding of neuropathic pruritus is needed. Diagnostic workup of intractable pruritus should include advanced imaging to detect ongoing nerve root compression. If diagnostic studies suggest radiculopathy, epidural steroid injection should be considered. Because the autonomic nervous system may be involved in complex chronic pain or pruritic syndromes, sympatholysis via such techniques as stellate ganglion block might be effective. PMID:19777867

    Background Lumbar spinal stenosis is a pathological condition of the spinal channel with its concentric narrowing with presence of specific clinical syndrome. Absence of the clear unified radiological signs is the one of the basic problems of the lumbar spinal stenosis. Purpose The authors seek to create method of assessment of the spinal canal narrowing degree, based on anatomical aspects of lumbar spinal stenosis. Study Design Development of diagnostic criteria based on analysis of a consecutive patients group and a control group. Methods Thirty seven patients (73 stenotic segments) with mean age 62,4 years old were involved in the study. Severity of clinical symptoms has been estimated by the measuring scales: Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSQ). Mean number of the stenotic segments was 1.97. For all patients 8 radiological criteria have been measured. In the control group have been included 37 randomly selected patients (volunteers) in mean age of 53,4 years old without stenosis signs and narrowing of the spinal canal on the MRI imaging (73 segments total). Measurements were performed at the middle of intervertebral disc and facet joints level. Results For description of the state of spinal canal we offer the coefficient: ratio of the lateral canals total area to the cross-sectional area of the dural sac (“coefficient of stenosis”). Comparison of mean values of “coefficient of stenosis” for main and control groups showed statistically significant differences (t = -12,5; p < 0.0001). Strong statistically significant correlation with the ODI and SSS scales was revealed for the obtained coefficient (p <0.05). Conclusions In our study new method of assessment of the spinal canal narrowing degree has been applied. Promising results have been obtained in a small group of patients. It is necessary to check the data on a large sample of recommendations for its clinical application. PMID:25834777

    We sought to assess the extent to which pain relief in chronic back and leg pain (CBLP) following spinal cord stimulation (SCS) is influenced by patient-related factors, including pain location, and technology factors. A number of electronic databases were searched with citation searching of included papers and recent systematic reviews. All study designs were included. The primary outcome was pain relief following SCS, we also sought pain score (pre- and post-SCS). Multiple predictive factors were examined: location of pain, history of back surgery, initial level of pain, litigation/worker's compensation, age, gender, duration of pain, duration of follow-up, publication year, continent of data collection, study design, quality score, method of SCS lead implant, and type of SCS lead. Between-study association in predictive factors and pain relief were assessed by meta-regression. Seventy-four studies (N = 3,025 patients with CBLP) met the inclusion criteria; 63 reported data to allow inclusion in a quantitative analysis. Evidence of substantial statistical heterogeneity (P < 0.0001) in level of pain relief following SCS was noted. The mean level of pain relief across studies was 58% (95% CI: 53% to 64%, random effects) at an average follow-up of 24 months. Multivariable meta-regression analysis showed no predictive patient or technology factors. SCS was effective in reducing pain irrespective of the location of CBLP. This review supports SCS as an effective pain relieving treatment for CBLP with predominant leg pain with or without a prior history of back surgery. Randomized controlled trials need to confirm the effectiveness and cost-effectiveness of SCS in the CLBP population with predominant low back pain. PMID:23834386

    Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity. Although many of these complications remain uncommon, the range of possible morbidities is wide and includes multiple organ systems. Perioperative visual loss (POVL) is a well described, but uncommon complication that may occur due to ischemia to the optic nerve, retina, or cerebral cortex. Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery. Peripheral nerve injuries, such as those caused by prolonged traction to the brachial plexus, are more commonly encountered postoperative events. Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning, albeit rarely. Other uncommon positioning complications such as tongue swelling resulting in airway compromise, femoral artery ischemia, and avascular necrosis of the femoral head have also been reported. Many of these are well-understood and largely avoidable through thoughtful attention to detail. Other complications, such as POVL, remain incompletely understood and thus more difficult to predict or prevent. Here, the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity.

    We report a case of a 35-year-old male who underwent thoracoabdominal aortic repair of a chronic dissecting aortic aneurysm, Crawford extent II. Preoperative computed tomography showed thrombosis of almost all intercostal arteries. Precise diagnostic assessment demonstrated the Adamkiewicz artery originating from the left lateral thoracic artery and subscapular artery, which would have been at risk after using a standard Stoney's incision, thus potentially causing paraplegia or paraparesis due to spinal cord ischemia. We modified the lateral thoracic incision anteriorly and successfully preserved the collateral arteries without impairing the spinal cord function. PMID:27549554

    Myelitis, or inflammation of the spinal cord, produces a characteristic clinical syndrome. Among the many causes of myelitis are the prototypical demyelinating diseases multiple sclerosis and neuromyelitis optica, each of which has distinct clinical, pathologic, and radiographic features. Less distinct are the myelitides associated with systemic autoimmune conditions like sarcoidosis and lupus. Nondemyelinating conditions such as arachnoiditis, dural arteriovenous fistula, and tumor infiltration may also produce inflammation of the spinal cord. The objective of this review is to aid the clinician in the radiographic diagnosis of noninfectious inflammatory diseases of the spinal cord. PMID:27430439

    The incidence of permanent injury to the spinal cord as a complication of radiation therapy generally correlates positively with total radiation dosage. However, several reports in the literature have indicated that fraction size is also an important factor in the development or nondevelopment of late injuries in normal tissue. To determine the effect of fraction size on the incidence of radiation-induced spinal cord injuries, we reviewed 144 cases of head and neck cancer treated at our institution between 1971 and 1980 with radiation greater than 5600 cGy to a portion of the cervical spinal cord. Most of these patients received greater than or equal to 6000 cGy, with fraction sizes ranging from 133 cGy to 200 cGy. Fifty-three of the 144 patients have been followed up for 2 years or more. Nearly half of these (26 patients) received greater than 6000 cGy with fraction sizes of 133 cGy to 180 cGy. Only 1 of the 53 (1.9%) has sustained permanent spinal cord injury; 20 months after completion of radiation treatments he developed Brown-Sequard syndrome. Our experience suggests that radiation injuries to the spinal cord correlate not only with total radiation dosage, but also with fraction size; low fraction sizes appear to decrease the incidence of such injuries.

    May-Thurner syndrome is an anatomic variant where the right common iliac artery compresses the left common iliac vein. The variant exists in a significant portion of the population, but is usually asymptomatic; however, clinically significant stenosis can occur by iatrogenic means. In this report, we describe a patient who presents with left lower extremity pain and swelling. Initial workup for deep vein thrombosis was negative. After being referred to our venous clinic, a magnetic resonance angiography revealed narrowing of the left common iliac vein with a tortuous right common iliac artery crossing over the constriction. During left iliac vein stent placement, a pedicle screw from a prior L2-S1 spinal fusion was noted to be perforated through L5 vertebral body impinging the posterior aspect of the vein. This case demonstrates that increased scrutiny must be applied when dealing with pathology in close proximity to any implanted medical device. PMID:26912480

    Hepatopulmonary syndrome is characterized by the presence of liver disease, pulmonary vascular dilatations, and arterial hypoxemia. It is usually associated with cirrhosis of any origin, but has been described in other liver diseases, both acute and chronic, and not always associated with portal hypertension. The gold standard method to detect pulmonary vascular dilations is contrast enhancement echocardiography with saline and is essential for the diagnosis of hepatopulmonary syndrome. These dilatations reflect changes in the pulmonary microvasculature (vasodilatation, intravascular monocyte accumulation, and angiogenesis) and induce a ventilation/perfusion mismatch, or even true intrapulmonary shunts, which eventually trigger hypoxemia. This syndrome worsens patients' prognosis and impairs their quality of life and may lead to the need for liver transplantation, which is the only effective and definitive treatment. In this article, we review the etiological, pathophysiological, clinical and therapeutic features of this syndrome. PMID:25840463

    Pancreaticoduodenal artery aneurysms are a rare type of visceral artery aneurysm, whose rupture is associated with high mortality. These aneurysms are of particular interest because local haemodynamic change caused by coeliac artery obstruction plays an important role in their development. However, the pathophysiological mechanism of coeliac artery obstruction is not completely understood. Pressure from the median arcuate ligament is most frequently reported cause. Although it is well-known that stenosis or occlusion of the visceral vessels may be caused by aortic syndrome, reports of pancreaticoduodenal artery aneurysm associated with coeliac artery occlusion due to aortic syndrome are extremely rare. Our case indicates a new aetiology for a pancreaticoduodenal artery aneurysm and demonstrates the rapid deterioration of the patient affected. PMID:27122676

    We present the case of a 12-year-old girl who underwent an uncomplicated posterior spinal fusion with instrumentation for scoliosis and who later developed nausea, emesis, and abdominal pain. We discuss the epidemiology, prevalence, anatomic findings, symptoms, diagnostic tests, and clinical management, including nonsurgical and surgical therapies, of superior mesenteric artery syndrome (SMAS), a rare condition. Over a 2-week period, the patient developed an uncommon type of bowel obstruction likely related to her initial thin body habitus, correction of her deformity, and weight loss after surgery. The patient returned to the operating room for placement of a Stamm gastrostomy feeding tube with insertion of a transgastric-jejunal (G-J) feeding tube. The patient had the G-J feeding tube in place for approximately 6 weeks to augment her enteral nutrition. As she gained weight, her duodenal emptying improved, and she gradually transitioned to normal oral intake. She has done well since the G-J feeding tube was removed. Posterior spinal fusion for adolescent idiopathic scoliosis is a relatively common procedure, and SMAS is a rare condition. However, in the case of an asthenic adolescent with postoperative weight loss, intestinal obstruction can develop. When planning operative spinal correction in scoliosis patients who have a low body mass index at the time of surgery and who have increased thoracic stiffness, be alert for signs and symptoms of SMAS. This rare complication can develop, and timely diagnosis and medical management will decrease morbidity and shorten the length of time needed for nutritional rehabilitation. PMID:26372764

    Little is known about cell death in spinal cord tissue following compression injury, despite compression being a key component of spinal injuries. Currently models are used to mimic compression injury in animals and the effects of the compression evaluated by observing the extent and duration of recovery of normal motor function in the days and weeks following the injury. A fibreoptic photoplethysmography system was used to investigate whether pulsation of the small arteries in the spinal cord occurred before, during and after compressive loads were applied to the tissue. It was found that the signal amplitudes were reduced and this reduction persisted for at least five minutes after the compression ceased. It is hoped that results from this preliminary study may improve knowledge of the mechanism of spinal cord injury.

    The antiphospholipid syndrome causes venous, arterial, and small-vessel thrombosis; pregnancy loss; and preterm delivery for patients with severe pre-eclampsia or placental insufficiency. Other clinical manifestations are cardiac valvular disease, renal thrombotic microangiopathy, thrombocytopenia, haemolytic anaemia, and cognitive impairment. Antiphospholipid antibodies promote activation of endothelial cells, monocytes, and platelets; and overproduction of tissue factor and thromboxane A2. Complement activation might have a central pathogenetic role. Of the different antiphospholipid antibodies, lupus anticoagulant is the strongest predictor of features related to antiphospholipid syndrome. Therapy of thrombosis is based on long-term oral anticoagulation and patients with arterial events should be treated aggressively. Primary thromboprophylaxis is recommended in patients with systemic lupus erythematosus and probably in purely obstetric antiphospholipid syndrome. Obstetric care is based on combined medical-obstetric high-risk management and treatment with aspirin and heparin. Hydroxychloroquine is a potential additional treatment for this syndrome. Possible future therapies for non-pregnant patients with antiphospholipid syndrome are statins, rituximab, and new anticoagulant drugs. PMID:20822807

    Preoperative medication by inhibitors of angiotensin-converting enzyme (ACE) in coronary artery patients predisposes to vasoplegic shock early after coronary artery bypass grafting. Although in the majority of the cases this shock is mild, in some of them it appears as a situation, "intractable" to high-catecholamine dose medication. In this study we examined the possible role of prophylactic infusion of low-dose vasopressin, during and for the four hours post-bypass after cardiopulmonary bypass, in an effort to prevent this syndrome. In addition, we studied the influence of infused vasopressin on the hemodynamics of the patients, as well as on the postoperative urine-output and blood-loss. In our study 50 patients undergoing coronary artery bypass grafting were included in a blind-randomized basis. Two main criteria were used for the eligibility of patients for coronary artery bypass grafting: ejection fraction between 30-40%, and patients receiving ACE inhibitors, at least for four weeks preoperatively. The patients were randomly divided in two groups, the group A who were infused with 0.03 IU/min vasopressin and the group B who were infused with normal saline intraoperativelly and for the 4 postoperative hours. Measurements of mean artery pressure (MAP), central venous pressure (CVP), systemic vascular resistance (SVR), ejection fracture (EF), heart rate (HR), mean pulmonary artery pressure (MPAP), cardiac index (CI) and pulmonary vascular resistance (PVR) were performed before, during, and after the operation. The requirements of catecholamine support, the urine-output, the blood-loss, and the requirements in blood, plasma and platelets for the first 24 hours were included in the data collected. The incidence of vasodilatory shock was significantly lower (8% vs 20%) in group A and B respectively (p = 0,042). Generally, the mortality was 12%, exclusively deriving from group B. Postoperatively, significant higher values of MAP, CVP, SVR and EF were recorded in

Patients with Eisenmenger syndrome suffer a high risk of complications in connection with acute medical conditions, extra-cardiac surgery and pregnancy. This article describes the precautions that should be taken to reduce morbidity and mortality in these patients. PMID:19416617

    If vertebral artery occlusion occurs in degenerative arterial disease it is almost invariably left-sided, but in vertebral artery deficiency syndromes associated with oral contraceptives a striking preponderance of right-sided involvement has been shown. This observation adds support to the view that causes other than changes in the wall of the vessel at the site of occlusion must be sought as an explanation of the occlusion. PMID:1252812

    Human studies in the past three decades have provided us with an emerging understanding of how cortical and spinal networks collaborate to ensure the vast repertoire of human behaviors. Humans have direct cortical connections to spinal motoneurons, which bypass spinal interneurons and exert a direct (willful) muscle control with the aid of a context-dependent integration of somatosensory and visual information at cortical level. However, spinal networks also play an important role. Sensory feedback through spinal circuitries is integrated with central motor commands and contributes importantly to the muscle activity underlying voluntary movements. Regulation of spinal interneurons is used to switch between motor states such as locomotion (reciprocal innervation) and stance (coactivation pattern). Cortical regulation of presynaptic inhibition of sensory afferents may focus the central motor command by opening or closing sensory feedback pathways. In the future, human studies of spinal motor control, in close collaboration with animal studies on the molecular biology of the spinal cord, will continue to document the neural basis for human behavior.

    We report acute radiation dermatitis on a patient's back and left arm, which developed 4 weeks after endovascular embolisation of a spinal arteriovenous malformation. Vesciculation and erosions were followed by a gradual re-epithelisation of the skin resulting in rectangular hyperpigmented patches that resolved almost completely within 1 month. Fluoroscopic radiodermatitis has been reported with more frequency over the past decades because of the rise in duration and number of procedures performed under fluoroscopic guidance. Articles concerning this issue are mostly limited to case reports after coronary interventions, renal artery catheterisations, transjugular intrahepatic portosystemic shunt procedures and embolisations of intracranial arteriovenous malformation. To the best of our knowledge, only two cases of radiation dermatitis after spinal arteriovenous malformation embolisation have been reported to date. PMID:27166008

    The authors present a review of spinal cord blood supply, discussing the anatomy of the vascular system and physiological aspects of blood flow regulation in normal and injured spinal cords. Unique anatomical functional properties of vessels and blood supply determine the susceptibility of the spinal cord to damage, especially ischemia. Spinal cord injury (SCI), for example, complicating thoracoabdominal aortic aneurysm repair is associated with ischemic trauma. The rate of this devastating complication has been decreased significantly by instituting physiological methods of protection. Traumatic SCI causes complex changes in spinal cord blood flow, which are closely related to the severity of injury. Manipulating physiological parameters such as mean arterial blood pressure and intrathecal pressure may be beneficial for patients with an SCI. Studying the physiopathological processes of the spinal cord under vascular compromise remains challenging because of its central role in almost all of the body's hemodynamic and neurofunctional processes.

    Cerebral and spinal vascular systems are organized individually, and they then conjugate at their border, through the integration of basilar artery and vertebral arteries. Zebrafish (Danio rerio) is an ideal organism for studying early vascular development, and the precise procedure of cranial and truncal vascular formation has been previously demonstrated using this model. However, the stepwise process of the integration between the brain and spinal cord has not been clearly elucidated. In this study, we describe the integration of the independent vascular systems for the brain and spinal cord, using transgenic zebrafish expressing enhanced green fluorescent protein in endothelial cells. Initially, basilar artery and primordial hindbrain channels, into which internal carotid arteries supplied blood, were connected with dorsal longitudinal anastomose vessels, via the first intersegmental artery. This initial connection was not influenced by flow dynamics, suggesting that vascular integration in this region is controlled by genetic cues. Vertebral arteries were formed individually as longitudinal vessels beneath the spinal cord, and became integrated with the basilar artery during subsequent remodeling. Furthermore, we confirmed the basal vasculature was well conserved in adult zebrafish. Observations of vascular integration presented herein will contribute to an understanding of regulatory mechanisms behind this process. PMID:26234750

    The effect of spinal anesthesia on drug disposition was determined in six dogs with chronically implanted vascular catheters using propranolol as a model compound. On the first study day, 40 mg of unlabeled propranolol and 200 microCi of (3H)propranolol were injected into the portal and femoral veins respectively. Arterial blood samples were taken for 4 hr for measurement of plasma concentrations of labeled and unlabeled propranolol by high-pressure liquid chromatography (HPLC) and of (3H)propranolol by liquid scintillation counting of the HPLC eluant corresponding to each propranolol peak. Twenty-four hr later, spinal anesthesia was induced with tetracaine (mean dose 20.7 +/- 0.6 mg) with low sacral to midthoracic levels and the propranolol infusions and sampling were then repeated. Spinal anesthesia had no significant effect on either the intrinsic clearance of propranolol (2.01 +/- 0.75 L/min before and 1.9 +/- 0.7 L/min during spinal anesthesia), or on mean hepatic plasma flow (2.01 +/- 0.5 L/min before and 1.93 +/- 0.5 L/min during spinal anesthesia). The systemic clearance and elimination half-life of propranolol were also unchanged by spinal anesthesia (0.9 +/- 0.23 L/min on the first day, 0.7 +/- 0.1 L/min during spinal anesthesia; and 101 +/- 21 min on the first day, 115 +/- 16 min during spinal anesthesia, respectively). The volume of distribution (Vd) of propranolol was similarly unaffected by spinal anesthesia.

    Access-site vascular complications in patients undergoing transradial coronary procedures are rare but may have relevant clinical consequences. The aim of the study was to evaluate: (1) radial artery's (RA) patency immediately after the procedure and in long-term observation, (2) factors influencing the frequency of radial artery's occlusion (RAO) after percutaneous coronary intervention (PCI) procedures performed via transradial access in the group of 220 patients with acute coronary syndromes (ACS). RA ultrasound was performed 48-72 h after the procedure and in those who were diagnosed with RAO-again after 6-12 months. According to the ultrasonographic findings, the patients were divided into two sub-groups: 187 pts (85 %) with patent RA after PCI and 33 pts (15 %) with RAO. Both sub-groups significantly statistically differed with regard to the frequency of local hematomas-15 versus 27.3 % (p = 0.02), the frequency of applying IIbIIIa inhibitors in PCI-6.4 versus 15.1 % (p = 0.015) and procedure duration-0.59 ± 0.37 versus 0.77 ± 0.38 (p = 0.014), respectively. In a multifactorial analysis the only factor influencing RA patency promptly after the procedure was PCI duration (p < 0.05, r = -0.22). In the follow-up, right RA remained still obstructed in 28 patients (12.7 %) whereas in five patients (2.3 %) the regular flow in RA was resumed. The chronic RAO was clinically silent. Due to insignificant frequency of the occurrence of RAO after PCI procedure in patients with ACS as well as practically lack of clinical consequences of this artery's occlusion in long-term observation, we do not see any implications to routine ultrasound periprocedural RA evaluation.

    Vascular changes after acute spinal cord trauma are important factors that predispose quadriplegia, in most cases irreversible. Repair of the spinal blood flow helps the spinal cord recovery. The average time to arrive and perform surgery is 3 h in most cases. It is important to determine the critical ischemia time in order to offer better functional prognosis. A spinal cord section and vascular clamping of the spinal anterior artery at C5–C6 model was used to determine critical ischemia time. The objective was to establish a critical ischemia time in a model of acute spinal cord section. Four groups of dogs were used, anterior approach and vascular clamp of spinal anterior artery with 1, 2, 3, and 4 h of ischemia and posterior hemisection of spinal cord at C5–C6 was performed. Clinical evaluation was made during 12 weeks and morphological evaluation at the end of this period. We obtained a maximal neurological coordination at 23 days average. Two cases showed sequels of right upper limb paresis at 1 and 3 ischemia hours. There was nerve conduction delay of 56% at 3 h of ischemia. Morphological examination showed 25% of damaged area. The VIII and IX Rexed’s laminae were the most affected. The critical ischemia time was 3 h. Dogs with 4 h did not exhibit any recovery. PMID:17024402

    An experimental model of spinal epidural abscess was developed in rabbits by injecting Staphylococcus aureus into the posterior thoracolumbar epidural space. This model has been shown to reproduce the neurological, bacteriological, and radiological aspects of the human disease. In this study, the effect of the infectious epidural mass on the vasculature of the spinal cord in paraplegic rabbits was studied using microangiographic techniques. The normal vascular anatomy of the rabbit spinal cord was defined in control experiments. Vascular proliferation was demonstrated in the epidural space surrounding the abscesses. Anterior and paired posterior spinal arteries remained patent in paraplegic rabbits with mild or moderate spinal cord compression and in some cases of severe compression. In animals with severe compression, the anterior epidural venous plexus remained patent, but the dorsal spinal vein was occluded. Occlusion of perforating arteries occurred only with extreme spinal cord compression. These data indicate that the initial neurological deficit associated with experimental spinal epidural abscess is not due to vascular thrombosis. PMID:2454302

    We report a case of Nicolau syndrome in a 15 months old girl following an intramuscular injection of penicillin 6.3.3 in her left buttock. This case is unique because she developed compartment syndrome in her left calf far from her injection site. Her toe’s tips gangrened in the course of her ailment. We hypothesized that the compartment syndrome might be produced by a probable intra-arterial injection that had produced embolic obstruction of the small and medium size arteries in her leg or a probable perineural or periarteial injection had produced secondary sympathetic stimulation, extensive vasospasm, compromised microcirculation and the development of compartment syndrome.

    Two distinct terms are used to describe vascular thoracic outlet syndrome (TOS) depending on which structure is predominantly affected: venous TOS (due to subclavian vein compression) and arterial TOS (due to subclavian artery compression). Although the venous and arterial subtypes of TOS affect only 3% and <1% of all TOS patients respectively, the diagnostic and management approaches to venous and arterial TOS have undergone considerable evolution due to the recent emergence of minimally invasive endovascular techniques such as catheter-directed arterial and venous thrombolysis, and balloon angioplasty. In this review, we discuss the anatomical factors, etiology, pathogenesis and clinical presentation of vascular TOS patients. In addition, we use the most up to date observational evidence available to provide a contemporary approach to the diagnosis and management of venous TOS and arterial TOS patients. PMID:27568153

    2014-01-01

    We report a case of cervicomedullary compression by an anomalous vertebral artery treated using microsurgical decompression with intraoperative monitoring. A 68-year-old woman presented with posterior neck pain and gait disturbance. MRI revealed multiple abnormalities, including an anomalous vertebral artery that compressed the spinal cord at the cervicomedullary junction. Suboccipital craniectomy with C1 laminectomy was performed. The spinal cord was found to be compressed by the vertebral arteries, which were retracted dorsolaterally. At that time, the somatosensory evoked potential (SSEP) changed. After release of the vertebral artery, the SSEP signal normalized instantly. The vertebral artery was then lifted gently and anchored to the dura. There was no other procedural complication. The patient's symptoms improved. This case demonstrates that intraoperative monitoring may be useful for preventing procedural complications during spinal cord microsurgical decompression. PMID:25628814

    Acute myelopathy is increasingly being recognized as a common neurological complication of schistosomiasis. Schistosome eggs reach the spinal cord either as egg emboli or as eggs produced by ectopic worms. This leads to inflammatory reaction and granuloma formation around the eggs. Patients with spinal schistosomiasis may not have clinical evidence of schistosomiasis. The typical clinical picture is that of lumbar pain preceded by other symptoms by hours or up to 3 weeks. Patients may present with paraparesis, urinary retention or paraplegia. Definitive diagnosis of spinal cord schistosomiasis is by detection of the eggs in a spinal cord biopsy or at autopsy. However, most cases are diagnosed based on a presumptive diagnosis that depends on a suggestive clinical picture, history or evidence of active schistosomiasis and exclusion of other conditions. Investigations include stools and urine examination for schistosome eggs, blood tests, magnetic resonance imaging (MRI) and examination of the cerebrospinal fluid. Treatment of cases is mainly by praziquantel, corticosteroids, surgical intervention and rehabilitation.

    OBJECT The arterial basket of the conus medullaris (ABCM) consists of 1 or 2 arteries arising from the anterior spinal artery (ASA) and circumferentially connecting the ASA and the posterior spinal arteries (PSAs). The arterial basket can be involved in arteriovenous fistulas and arteriovenous malformations of the conus. In this article, the authors describe the microsurgical anatomy of the ABCM with emphasis on its morphometric parameters and important role in the intrinsic blood supply of the conus medullaris. METHODS The authors performed microsurgical dissections on 16 formalin-fixed human spinal cords harvested within 24 hours of death. The course, diameter, and branching angles of the arteries comprising the ABCM were then identified and measured. In addition, histological sections were obtained to identify perforating vessels arising from the ABCM. RESULTS The ASA tapers as it nears the conus medullaris (mean preconus diameter 0.7 ± 0.12 mm vs mean conus diameter 0.38 ± 0.08 mm). The ASA forms an anastomotic basket with the posterior spinal artery (PSA) via anastomotic branches. In most of the specimens (n= 13, 81.3%), bilateral arteries formed connections between the ASA and PSA. However, in the remaining specimens (n= 3, 18.7%), a unilateral right-sided anastomotic artery was identified. The mean diameter of the right ABCM branch was 0.49 ± 0.13 mm, and the mean diameter of the left branch was 0.53 ± 0.14 mm. The mean branching angles of the arteries forming the anastomotic basket were 95.9° ± 36.6° and 90° ± 34.3° for the right- and left-sided arteries, respectively. In cases of bilateral arterial anastomoses between the ASA and PSA, the mean distance between the origins of the arteries was 4.5 ± 3.3 mm. Histological analysis revealed numerous perforating vessels supplying tissue of the conus medullaris. CONCLUSIONS The ABCM is a critical anastomotic connection between the ASA and PSA, which play an important role in the intrinsic blood supply

    This case report concerns a 40-year-old male who had previously been treated for an esophageal varix rupture, at the age of 30 years. The medical examination at that time revealed occlusion of the inferior vena cava in the proximity of the liver, leading to the diagnosis of the patient with Budd-Chiari syndrome. The progress of the patient was therefore monitored in an outpatient clinic. The patient had no history of drinking or smoking, but had suffered an epileptic seizure in 2004. The patient's family history revealed nothing of note. In February 2012, color Doppler ultrasonography (US) revealed a change in the blood flow in the right portal vein branch, from hepatopetal to hepatofugal, during deep inspiration. Arrival time parametric imaging (At-PI), using Sonazoid-enhanced US, was subsequently performed to examine the deep respiration-induced changes observed in the hepatic parenchymal perfusion. US images captured during deep inspiration demonstrated hepatic parenchymal perfusion predominantly in red, indicating that the major blood supply was the hepatic artery. During deep expiration, the portal venous blood flow remained hepatopetal, and hepatic parenchymal perfusion was displayed predominantly in yellow, indicating that the portal vein was the major source of the blood flow. The original diagnostic imaging results were reproduced one month subsequently by an identical procedure. At-PI enabled an investigation into the changes that were induced in the hepatic parenchymal perfusion by a compensatory mechanism involving the hepatic artery. These changes occurred in response to a reduction in the portal venous blood flow, as is observed in the arterialization of hepatic blood flow that is correlated with the progression of chronic hepatitis C. It has been established that the peribiliary capillary plexus is important in the regulation of hepatic arterial blood flow. However, this case demonstrated that the peribiliary capillary plexus also regulates acute

    Regeneration after spinal cord injury is a serious health issue and there is no treatment for ailing patients. To understand regeneration of the spinal cord we used a system where regeneration occurs naturally, such as the lamprey. In this work, we analyzed the stress response of the spinal cord to tensile loading and obtained the mechanical properties of the cord both in vitro and in vivo. Physiological measurements showed that the spinal cord is pre-stressed to a strain of 10%, and during sinusoidal swimming, there is a local strain of 5% concentrated evenly at the mid-body and caudal sections. We found that the mechanical properties are homogeneous along the body and independent of the meninges. The mechanical behavior of the spinal cord can be characterized by a non-linear viscoelastic model, described by a modulus of 20 KPa for strains up to 15% and a modulus of 0.5 MPa for strains above 15%, in agreement with experimental data. However, this model does not offer a full understanding of the behavior of the spinal cord fibers. Using polymer physics we developed a model that relates the stress response as a function of the number of fibers.

    Fibromuscular dysplasia (FMD) involving the coronary arteries is an uncommon but important condition that can present as acute coronary syndrome, left ventricular dysfunction, or potentially sudden cardiac death. Although the classic angiographic “string of beads” that may be observed in renal artery FMD does not occur in coronary arteries, potential manifestations include spontaneous coronary artery dissection, distal tapering or long, smooth narrowing that may represent dissection, intramural hematoma, spasm, or tortuosity. Importantly, FMD must be identified in at least one other noncoronary arterial territory to attribute any coronary findings to FMD. Although there is limited evidence to guide treatment, many lesions heal spontaneously; thus, a conservative approach is generally preferred. The etiology is poorly understood, but there are ongoing efforts to better characterize FMD and define its genetic and molecular basis. This report reviews the clinical course of FMD involving the coronary arteries and provides guidance for diagnosis and treatment strategies. PMID:25190240

    The trigeminal artery is one of four primitive anastomoses between the internal carotid artery and vertebrobasilar system that regresses in the sixth week of fetal development. A persistent trigeminal artery (PTA) is generally an incidental finding but may also be associated with intracranial vascular pathologies such as aneurysms, arteriovenous malformations, and cranial nerve compression syndromes. We present an extremely rare case of a right PTA with an associated bleeding fusiform aneurysm located in the carotidian (lateral) part of the PTA. In addition, this rare anatomic variation was associated with bilateral absence of the posterior communicating arteries, a left posterior cerebral artery originating from the left internal carotid artery, and agenesis of the A1 segment of the left anterior cerebral artery.

    Stiffness of large arteries has been long recognized as a significant determinant of pulse pressure. However, it is only in recent decades, with the accumulation of longitudinal data from large and varied epidemiological studies of morbidity and mortality associated with cardiovascular disease, that it has emerged as an independent predictor of cardiovascular risk. This has generated substantial interest in investigations related to intrinsic causative and associated factors responsible for the alteration of mechanical properties of the arterial wall, with the aim to uncover specific pathways that could be interrogated to prevent or reverse arterial stiffening. Much has been written on the haemodynamic relevance of arterial stiffness in terms of the quantification of pulsatile relationships of blood pressure and flow in conduit arteries. Indeed, much of this early work regarded blood vessels as passive elastic conduits, with the endothelial layer considered as an inactive lining of the lumen and as an interface to flowing blood. However, recent advances in molecular biology and increased technological sophistication for the detection of low concentrations of biochemical compounds have elucidated the highly important regulatory role of the endothelial cell affecting vascular function. These techniques have enabled research into the interaction of the underlying passive mechanical properties of the arterial wall with the active cellular and molecular processes that regulate the local environment of the load-bearing components. This review addresses these emerging concepts. PMID:26587425

    Abstract Objective To evaluate an a priori threshold for advanced imaging in patients with spinal pain. Design Patients with spinal pain in any region for 6 to 52 weeks were assessed to determine if radiologic studies beyond x-ray scans were indicated, including magnetic resonance imaging (MRI), computed tomography (CT), and radionuclide bone scans. An a priori threshold was set before MRI, CT, or bone scans would be considered. Those who did not have MRI, CT, or bone scans ordered were followed for at least 1 year to determine if any of them went on to be diagnosed with a more serious spinal disorder (eg, infection, fracture, spondylitis, tumour, neurologic compression). Setting Four large primary care clinics in Edmonton, Alta. Participants A total of 1003 consecutively presenting patients with symptoms suspected to be related to the spine (for a duration of generally 6 to 52 weeks) who had not already undergone advanced imaging and did not have a diagnosis of nonbenign back pain. Main outcome measures Number of cases of nonbenign spinal disorder in participants who underwent advanced imaging and participants who did not undergo advanced imaging (ie, did not have any red flags). Results There were 399 women (39.8%) and 604 men (60.2%). The mean (SD) age of the group was 47.2 (14.6) years. The mean (SD) duration of symptoms was 15.1 (8.6) weeks. Of the 1003 participants, 110 met an a priori threshold for undergoing at least 1 of MRI, CT, or bone scan. In these 110 participants, there were newly diagnosed cases of radiculopathy (n = 12), including a case of cauda equina syndrome; spondyloarthropathy (n = 6); occult fracture (n = 2); solitary metastasis (n = 1); epidural lipomatosis (n = 1); osteomyelitis (n = 1), and retroperitoneal hematoma (n = 1), each of which was considered likely to be the cause of the patient’s spinal symptoms.

    Because it may cause paralysis, injury to the spine is one of the most feared traumas, and spinal cord injury is a major cause of disability. In the USA approximately 10,000 traumatic cervical spine fractures and 4000 traumatic thoracolumbar fractures are diagnosed each year. Although the number of individuals sustaining paralysis is far less than those with moderate or severe brain injury, the socioeconomic costs are significant. Since most of the spinal trauma patients survive their injuries, almost one out of 1000 inhabitants in the USA are currently being cared for partial or complete paralysis. Little controversy exists regarding the need for accurate and emergent imaging assessment of the traumatized spine in order to evaluate spinal stability and integrity of neural elements. Because clinicians fear missing occult spine injuries, they obtain radiographs for nearly all patients who present with blunt trauma. We are influenced on one side by fear of litigation and the possible devastating medical, psychologic and financial consequences of cervical spine injury, and on the other side by pressure to reduce health care costs. A set of clinical and/or anamnestic criteria, however, can be very useful in identifying patients who have an extremely low probability of injury and who consequently have no need for imaging studies. Multidetector (or multislice) computed tomography (MDCT) is the preferred primary imaging modality in blunt spinal trauma patients who do need imaging. Not only is CT more accurate in diagnosing spinal injury, it also reduces imaging time and patient manipulation. Evidence-based research has established that MDCT improves patient outcome and saves money in comparison to plain film. This review discusses the use, advantages and disadvantages of the different imaging techniques used in spinal trauma patients and the criteria used in selecting patients who do not need imaging. Finally an overview of different types of spinal injuries is given

    A patient undergoing radical extrapleural pneumonectomy for epithelioid malignant mesothelioma developed acute paraplegia postoperatively related to long-segment spinal cord ischemia. The usual area of concern for this complication is the T9 to T12 area where the artery of Adamkiewicz is most likely to originate. In this patient, there was ligation of only upper thoracic, ipsilateral segmental arteries from the T3 to T6 level, yet he still developed paraplegia. Our hypothesis is variant mid-thoracic vascular anatomy. Previously unreported, to our knowledge, this should be understood as a rare complication of this surgery. PMID:25091760

    A prospective study was made of 73 patients presenting in one year with abdominal pain provisionally diagnosed as of spinal origin. The criteria for audit of diagnosis and treatment are defined. The diagnosis was confirmed in 53 patients, 49 of whom had been treated with a lignocaine intercostal block in the relevant segment. Thirty-three of these (67.3%) had both complete and prolonged relief. It is suggested that the block causes interruption of a vicious circle of pain and muscle spasm in a 'spinal reflex pain syndrome'. PMID:860866

    Spinal cord stimulation (SCS) has become an established clinical option for treatment of refractory chronic pain. Current hardware and implantation techniques for SCS are already highly developed and continuously improving; however, equipment failures over the course of long-term treatment are still encountered in a relatively high proportion of the cases treated with it. Percutaneous SCS leads seem to be particularly prone to dislocation and insulation failures. We describe our experience of lead breakage in the inserted spinal cord stimulator to a complex regional pain syndrome patient who obtained satisfactory pain relief after the revision of SCS.

    A growing body of scientific evidence suggests that there is an association between occult spinal injury and abusive head trauma (previously known as shaken baby syndrome). Consideration needs to be given to the nature of these injuries, the possible causal mechanisms and what investigations should be undertaken to delineate the full extent of spinal involvement in infants with suspected abusive head trauma. This association has the potential to influence our understanding of the biomechanics and subsequent neuropathology associated with abusive head trauma. PMID:25501732

    Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid-internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

    Objective To identify adverse effects of spinal manipulation. Design Systematic review of papers published since 2001. Setting Six electronic databases. Main outcome measures Reports of adverse effects published between January 2001 and June 2006. There were no restrictions according to language of publication or research design of the reports. Results The searches identified 32 case reports, four case series, two prospective series, three case-control studies and three surveys. In case reports or case series, more than 200 patients were suspected to have been seriously harmed. The most common serious adverse effects were due to vertebral artery dissections. The two prospective reports suggested that relatively mild adverse effects occur in 30% to 61% of all patients. The case-control studies suggested a causal relationship between spinal manipulation and the adverse effect. The survey data indicated that even serious adverse effects are rarely reported in the medical literature. Conclusions Spinal manipulation, particularly when performed on the upper spine, is frequently associated with mild to moderate adverse effects. It can also result in serious complications such as vertebral artery dissection followed by stroke. Currently, the incidence of such events is not known. In the interest of patient safety we should reconsider our policy towards the routine use of spinal manipulation. PMID:17606755

    2006-04-15

    Fistula formation between a coronary artery bypass graft (CABG)and the pulmonary arterial circulation represents a rare cause of recurrent angina in patients following bypass grafting. Therapy has traditionally involved surgical ligation by open thoracotomy. We describe a case of left internal mammary artery-left upper lobe pulmonary artery fistula presenting as early recurrent angina following CABG. The fistula was embolized using platinum coils, resulting in symptomatic relief and improvement in myocardial perfusion on cardiac perfusion scintigraphy. Coil embolization should be considered a therapeutic option in patients with coronary-pulmonary steal syndrome.

    The aim of the study was to assess the effect of commonly used intravertebral anesthesia on bone cement implantation syndrome (BCIS) in aged patients undergoing hemiarthroplasty.The medical records of 1210 aged patients receiving hemiarthroplasty under intravertebral anesthesia were retrospectively reviewed. Anesthesia charts for all patients were reviewed for central venous pressure, mean arterial pressure, arterial oxygen saturation, and heart rate before, during, and after cementation. Each patient was classified into no BCIS (grade 0) or BCIS grade 1, 2, or 3 according to the degree of hypotension, arterial desaturation, or loss of consciousness around cementation. Changes in these grades after cementation were compared according to the ways of intravertebral anesthesia used.Among all included patients, 72.2% (874/1210) showed grade 1 or higher grade of BCIS after cementation. Compared with spinal-epidural anesthesia, single epidural anesthesia showed adjusted odds ratios (95% confidence interval) of 1.25 (1.13-1.43) for grade 1, 1.36 (0.83-2.06) for grade 2, and 3.55 (1.52-7.06) for marked postoperatively grade 3 of BCIS versus grade 0 (Type III P < 0.0001).Single epidural anesthesia was associated with increased odds for elevation of these grades after cementation compared with spinal-epidural anesthesia.

    Ischaemic heart disease is the most common cause of sudden death in the UK, and the most common cardiac cause of medical discharge from the Armed Forces. This paper reviews current evidence pertaining to the diagnosis and management of coronary artery disease from a military perspective, encompassing stable angina and acute coronary syndromes. Emphasis is placed on the limitations inherent in the management of acute coronary syndromes in the deployed environment. Occupational issues affecting patients with coronary artery disease are reviewed. Consideration is also given to the potential for coronary artery disease screening in the military, and the management of modifiable cardiovascular disease risk factors, to help decrease the prevalence of coronary artery disease in the military population.

    Aortic coarctation complicated with spinal artery aneurysm rupture is exceptionally rare and can be source of intraspinal hemorrhage with markedly poor prognosis. A 21-year-old man visited the emergency department because of chest and back pain along with immobility of bilateral lower limbs immediately after he woke up in the morning. Complete flaccid paraplegia and hypoesthesia in dermatome below bilateral T3 level and pain over axial region from neck to lumbar region were noted. A computed tomography excluded aortic dissection. Magnetic resonance imaging revealed a fusiform lesion involving the anterior epidural space from C7 to T2 level suspected of epidural hemorrhage, causing compression of spinal cord. He started intravenous corticosteroid but refused operation concerning the surgical benefits. Severe chest pain occurred with newly onset right bundle branch block that developed the other day. Coronary artery angiography revealed myocardial bridge of left anterior descending coronary artery at middle third and coarctation of aorta. He underwent thoracic endovascular aortic repair uneventfully. The patient was hemodynamically stable but with slow improvement in neurologic recovery of lower limbs. Aortic coarcation can cause paralysis by ruptured vascular aneurysms with spinal hemorrhage and chest pain that mimics acute aortic dissection. A history of hypertension at young age and aortic regurgitated murmurs may serve as clues for further diagnostic studies. Cautious and prudent evaluation and cross disciplines cares are essential for diagnosis and successful management of the disease. PMID:26275629

    Spinal injuries with neurologic sequelae are a rare but catastrophic injury. Many of these injuries might be preventable through proper parent and child education, particularly in water sports and vehicles accidents. A significant number of neurologic injuries are incomplete at the time of injury and proper rescue and initial care may make the difference between life as a quadriplegic and life as a normal individual. Because of the complexity of the management of the child with spinal injuries and their relative rarity, the definitive care is best undertaken at hospitals which specialize in the care of spinal injuries. Progressive deformity of the spine, a problem unique to childhood and adolescent paralysis, is often preventable with prolonged immobilization and protection of the spine. Progressive deformities which interfere with function or result in neurologic deterioration require an aggressive surgical approach. PMID:1124228

    Lumbar spinal stenosis, the results of congenital and degenerative constriction of the neural canal and foramina leading to lumbosacral nerve root or cauda equina compression, is a common cause of disability in middle-aged and elderly patients. Advanced neuroradiologic imaging techniques have improved our ability to localize the site of nerve root entrapment in patients presenting with neurogenic claudication or painful radiculopathy. Although conservative medical management may be successful initially, surgical decompression by wide laminectomy or an intralaminar approach should be done in patients with serious or progressive pain or neurologic dysfunction. Because the early diagnosis and treatment of lumbar spinal stenosis may prevent intractable pain and the permanent neurologic sequelae of chronic nerve root entrapment, all physicians should be aware of the different neurologic presentations and the treatment options for patients with spinal stenosis.

    Awareness that SCI pain is common emerged during the past decade. However, there are a number of unresolved issues. There is a need for variety of experimental models to reflect diversity of SCI pains. Current classification is not as user-friendly as it should be. More attention should be given to a condition of the spinal cord below and above the SCI lesion. A consensus for what is an optimal SCI functional assessment for patients with sensory complaints and pain should be developed. Further extensive SCI pain research is needed prior to spinal cord regeneration trials in order to be able to cope with a potential for newly developed pains that may appear during incomplete spinal cord regenerative attempts.

    Spinal angiolipomas are fairly infrequent benign tumours that are usually located in the epidural space of the thoracic column and represent 0.14% to 1.3% of all spinal tumours. Lumbar angiolipomas are extremely rare, representing only 9.6% of all spinal extradural angiolipomas. We report the case of a woman who complained of a lumbar pain of several months duration with no neurological focality and that had intensified in the last three days without her having had any injury or made a physical effort. The MR revealed an extradural mass L1-L2, on the posterior face of the medulla, decreasing the anteroposterior diameter of the canal. The patient symptoms improved after surgery. Total extirpation of the lesion is possible in most cases, and the prognosis is excellent even if the lesion is infiltrative. For this reason, excessively aggressive surgery is not necessary to obtain complete resection. PMID:27263067

    This study reviewed the epidemiology of brain and spinal tumours in Sarawak from January 2009 till December 2012. The crude incidence of brain tumour in Sarawak was 4.6 per 100,000 population/year with cumulative rate 0.5%. Meningioma was the most common brain tumour (32.3%) and followed by astrocytoma (19.4%). Only brain metastases showed a rising trend and cases were doubled in 4 years. This accounted for 15.4% and lung carcinoma was the commonest primary. Others tumour load were consistent. Primitive neuroectodermal tumour (PNET) and astrocytoma were common in paediatrics (60%). We encountered more primary spinal tumour rather than spinal metastases. Intradural schwannoma was the commonest and frequently located at thoracic level. The current healthcare system in Sarawak enables a more consolidate data collection to reflect accurate brain tumours incidence. This advantage allows subsequent future survival outcome research and benchmarking for healthcare resource planning. PMID:25934956

    Acute coronary syndromes result in a global impairment of coronary blood flow with nonculprit artery blood flow being associated with culprit artery flow and vice versa. Improvements in nonculprit artery flow are related to improvements in culprit artery flow after percutaneous intervention; nonculprit arteries with abnormal flow sustain greater improvements in their flow after culprit artery intervention.

    The article deals with the data concerning the efficacy of reconstructive operations and conservative treatment in patients presenting with pathological tortuosity of internal carotid arteries. The study included a total of 63 patients. The diagnostic algorithm was as follows: studying the haemodynamics of the internal carotid arteries, assessing the neurological status, and the methods of examining the eye. The patients were subdivided into two groups: Group One consisted of operated on patients (n=37) and Group Two comprising patients treated conservatively (n=26). The patients according to the neurological status were subdivided as follows: an asymptomatic course in 25 (39.7%) patients, transitory ischaemic attacks in 18 (28.6%) patients, dyscirculatory encephalopathy in 12 (19 %) patients, and stroke in 8 (12.7%) patients. Ophthalmological symptomatology was predominantly manifested by fits of amaurosis fugax in 19 (30.2%) patients and processes of maculodystrophy in 49 (77.8 %) patients. We assessed the immediate (day 30) and remote (1 year) results of conservative and surgical treatment. Group One patients demonstrated cessation of the amaurosis fugax attacks, improvement of the acuity of vision by 0.1 and more, enlargement of the borders of the field of vision, disappearance of scotomas, as well as arrest of the processes of maculodystrophy. Patients with transitory ischaemic attacks and dyscirculatory encephalopathy changed to the category of asymptomatic patients. In Group Two patients the dynamics of the neurological status was negative and the patients continued to experience fits of amaurosis fugas. The dynamics of the opthalmological symptomatology was weakly pronounced. PMID:24429568

    A wide range of neuromuscular diseases, including Parkinson disease, cerebral palsy, multiple sclerosis, and myopathy, are associated with spinal deformities. The most common postural deformities include anterocollis, Pisa syndrome (pleurothotonus), scoliosis, and camptocormia. Nonsurgical management of spinal deformity in patients with neuromuscular disease centers on maximizing the medical management of the underlying neurodegenerative pathology before surgical intervention is contemplated. Surgical management can include decompression alone, or decompression and fusion with short or long fusion constructs. Patients with neuromuscular disease are susceptible to postoperative medical complications, such as delirium, epidural hematomas, pulmonary emboli, and cardiac events. Compared with outcomes in the typical patient with spinal deformity, postoperative outcomes in patients with neuromuscular disease have higher rates of surgical complications, such as instrumentation failure, proximal junctional kyphosis, loss of correction, and the need for revision surgery, regardless of the magnitude of surgical treatment.

    Arterial tortuosity syndrome (ATS) is an autosomal recessive connective tissue disorder caused by loss-of-function mutations in SLC2A10, which encodes facilitative glucose transporter 10 (GLUT10). The role of GLUT10 in ATS pathogenesis remains an enigma, and the transported metabolite(s), i.e. glucose and/or dehydroascorbic acid, have not been clearly elucidated. To discern the molecular mechanisms underlying the ATS aetiology, we performed gene expression profiling and biochemical studies on skin fibroblasts. Transcriptome analyses revealed the dysregulation of several genes involved in TGFβ signalling and extracellular matrix (ECM) homeostasis as well as the perturbation of specific pathways that control both the cell energy balance and the oxidative stress response. Biochemical and functional studies showed a marked increase in ROS-induced lipid peroxidation sustained by altered PPARγ function, which contributes to the redox imbalance and the compensatory antioxidant activity of ALDH1A1. ATS fibroblasts also showed activation of a non-canonical TGFβ signalling due to TGFBRI disorganization, the upregulation of TGFBRII and connective tissue growth factor, and the activation of the αvβ3 integrin transduction pathway, which involves p125FAK, p60Src and p38 MAPK. Stable GLUT10 expression in patients' fibroblasts normalized redox homeostasis and PPARγ activity, rescued canonical TGFβ signalling and induced partial ECM re-organization. These data add new insights into the ATS dysregulated biological pathways and definition of the pathomechanisms involved in this disorder. PMID:26376865
