    Summary Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm. We present a case of a child with a giant ICA pseudoaneurysm after tonsillectomy, manifested by pulsing mass and respiratory distress, which was treated by endovascular approach, occluding the lesion and the proximal artery with Histoacryl. We reinforce that the endovascular approach is the better way to treat most of the traumatic vascular lesions. PMID:20594516

    Ultrasound-guided compression repair of a pseudoaneurysm is a simple, safe and effective therapy, and has been proposed as a first-line treatment for pseudoaneurysms caused by catheterization. Herein, we report a case of a pseudoaneurysm arising from a sport injury which was treated by this method. Obliteration of the track of the pseudoaneurysm induced manual thrombosis and successfully converted the pseudoaneurysm to haematoma. Understanding the mechanism and the procedure is the basis of success in the use of this treatment. PMID:9497979

    Post-traumatic hepatic artery pseudoaneurysm is uncommon, appearing in approximately 1% of hepatic trauma cases. Most are extrahepatic (80%) and have a late onset. Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications, especially breakage. Currently the treatment of choice is endovascular embolization with coils or the exclusion of the pseudoaneurysm using other intravascular devices. Recently there have been accounts of a treatment that combines embolization with coils and image-guided percutaneous human thrombin injection. We present a case of post-traumatic hepatic artery pseudoaneurysm that was successfully treated using this combined technique. PMID:21160978

    Introduction Inferior epigastric artery (IEA) pseudoaneurysms are recognised complications of abdominal wall procedures, and a variety of approaches including surgical excision and ligation, percutaneous procedures and conservative management have been employed in treating this rare complication. Methods We describe a case of an IEA pseudoaneurysm diagnosed on computed tomography (CT) angiography, 14 days following a laparoscopic assisted low anterior resection, which was managed successfully with surgical excision and ligation. A review of the literature identified 32 reports of this complication since 1973 with 69% of cases occurring since 2000. Findings The main aetiology of IEA pseudoaneurysm was abdominal surgery (n=20); 65% of cases were attributable to abdominal wound closure or laparoscopic surgery. Two-thirds (66%) of patients presented between 11 and 63 days, and all except 1 case presented with discomfort, abdominal mass or haemodynamic instability. Colour Doppler ultrasonography was the imaging modality of choice (n=18), either alone or in combination with computed tomography and/or angiography. Surgical ligation and excision and percutaneous coil embolisation formed the mainstay of attempted treatments (69%), particularly following treatment failure using an alternative technique. Conclusions The incidence of iatrogenic IEA pseudoaneurysms appears to be increasing. Awareness of this rare complication is of clinical importance to avoid excessive morbidity for affected individuals. PMID:26263930

    The case of a 30-year-old woman with a post-traumatic pseudoaneurysm of the superior mesenteric artery and associated celiac axis occlusion is presented. The patient was successfully treated with celiac artery recanalization and placement of a covered stent within the superior mesenteric artery. Follow-up at 3, 6, and 12 months and 3 years demonstrated patency of the covered stent and continued exclusion of the aneurysm. Although the long-term success of this procedure is unknown this management option should be considered where facilities are available, to reduce the increased morbidity associated with open surgical procedure.

    Objective: This study was designed to determine the incidence of arterial pseudoaneurysm in patients presenting with postpartum hemorrhage (PPH), to analyze the angiographic characteristics of pseudoaneurysms that cause PPH, and to evaluate the effectiveness of pelvic arterial embolization for the treatment of this condition.Study designEighteen women with pelvic arterial pseudoaneurysm were retrieved from a series of 588 consecutive patients with PPH treated by arterial embolization. Clinical files, angiographic examinations, and procedure details were reviewed. Results: The incidence of pseudoaneurysm was 3.06 % (18/588; 95 % confidence interval (CI): 1.82-4.8 %). A total of 20 pseudoaneurysms were found; 15/20 (75 %) were located on the uterine arteries. Angiography revealed extravasation of contrast material from pseudoaneurysm indicating rupture in 9 of 18 (50 %) patients. Arterial embolization was performed using gelatin sponge alone in 12 of 18 (67 %) patients or in association with metallic coils in 5 of 18 (28 %) patients or n-butyl-2-cyanoacrylate in 1 of 18 (6 %) patients. Arterial embolization allowed controlling the bleeding in all patients after one or two embolization sessions in 17 of 18 (94 %) and 1 of 18 patients (6 %) respectively, without complications, obviating the need for further surgery. Conclusions: Pseudoaneurysm is rarely associated with PPH. Arterial embolization is an effective and safe procedure for the treatment of PPH due to uterine or vaginal artery pseudoaneurysm. Our results suggest that gelatin sponge is effective for the treatment of ruptured pseudoaneurysms, although we agree that our series does not contain sufficient material to allow drawing definitive conclusions with respect to the most effective embolic material.

    Pseudoaneurysms of the lingual artery are extremely rare and are commonly iatrogenic in nature or less frequently a result of blunt or penetrating trauma. Traditionally, these vascular abnormalities have been repaired with open or endovascular techniques. Although ultrasound-guided percutaneous thrombin injection has become a standard treatment for superficial pseudoaneurysms, there are no reports of this being used in the treatment of lingual artery pseudoaneurysms. We report the case of a 26-year-old man who suffered a penetrating head and neck injury after an improvised explosive device blast in Iraq who presented with persistent oropharyngeal swelling. Color-flow Doppler ultrasonography revealed the classic yin/yang sign of a pseudoaneurysm, and a computed tomography scan was obtained that revealed a right lingual artery pseudoaneurysm. With the lack of endovascular capabilities and the excessive risk of open surgery, thrombin was injected directly into the pseudoaneurysm under ultrasound guidance. A computed tomography scan and Doppler ultrasonography revealed complete resolution of the aneurysm. This article presents the first reported case in the English literature of a lingual artery aneurysm after penetrating trauma managed successfully with ultrasound-guided percutaneous thrombin injection.

    We describe a case of an elderly man who presented with an upper arm swelling that had developed following a humeral fracture 8 months previously. The swelling was painless but associated with significantly diminished motor function of his right hand and concurrent paraesthaesia. On examination, a large pulsatile mass was identified and CT angiography confirmed the presence of an 11×7 cm brachial artery pseudoaneurysm. The patient underwent surgical repair in which a fragment of the humerus was found to have punctured the brachial artery resulting in a pseudoaneurysm. The patient had an uncomplicated postoperative period and was discharged 2 days later having regained some motor function in his right hand. PMID:24859555

    A 54-year-old male presented with intermittent massive hemorrhage from recurrent oropharyngeal cancer. The angiogram showed the encasements at the main trunk of the left internal carotid artery (ICA) and external carotid artery (ECA). Transcatheter arterial embolization (TAE) of the ECA with gelatin sponge particles and microcoils was performed. However, hemorrhage recurred several hours after the initial TAE. The second angiogram showed a large pseudoaneurysm of the ICA developing at the encasement on the initial angiogram. As a simple neurologic test, regional cerebral oxygenation (rSO{sub 2}) was assessed with and without manual compression of the common carotid artery (CCA). With compression of the left CCA, the rSO{sub 2} did not change. We therefore performed isolation of the pseudoaneurysm. We embolized proximally and distally to the ICA pseudoaneurysm with microcoils and the pseudoaneurysm disappeared. No major complications occurred and no massive hemorrhage recurred until death from the cancer. TAE was an effective treatment for massive hemorrhage caused by tumor invasion to ICA. Assessment of rSO{sub 2} was a simple and useful neurologic test predicting the cerebral blood flow to prevent complications of TAE.

    We report on a case of endovascular management of pseudoaneurysm of the cavernous segment of the internal carotid artery with covered stent reconstruction. A 36 years-old woman with a history of previous transsphenoidal approach for pituitary macroadenoma and false aneurysma formation was studied in a protocol that included balloon test occlusion and cerebral blood flow evaluation. An endovascular covered stent deployment in the area of the carotid laceration was performed with isolation of the aneurysm from the circulation and maintenance of the carotid flow. Helical angio-CT and cerebral digital subtraction angiography showed the carotid preservation without stenosis in the stented area. In conclusion, endovascular stent reconstruction for post-transsphenoidal carotid artery laceration and false aneurysm is demonstrated as useful technical adjunct in the management strategy and with the potential for carotid sacrifice morbidity avoidance.

    A 48-year-old woman with severe juvenile-onset rheumatoid arthritis presented with a bleeding cutaneous sinus distal to her right total hip replacement scar. Methicillin resistant Staphylococcus aureus (MRSA) was isolated on culture. She had previously undergone bilateral total hip and knee replacements at aged 23 and six years later had the right knee prosthesis removed for infection, with subsequent osteomyelitis of the femoral shaft and right total hip prosthesis disruption. Peripheral arteriography was performed in view of persistent bleeding from the sinus, which revealed a 6 cm false aneurysm filling from and compressing the right external iliac artery (EIA). A PTFE-covered, balloon expandable JOSTENT was deployed in the right EIA, successfully excluding the false aneurysm and preventing further bleeding from the sinus. No graft infection was reported at 12 months. This case illustrates the potential use of endovascular stent-grafting in the treatment of an infected pseudoaneurysm.

    2014-01-01

    Inferior phrenic artery (IPA) pseudoaneurysm is an extremely rare complication of chronic pancreatitis with only three cases reported in the literature so far. It is a serious condition that can be life-threatening if not diagnosed promptly. Recent advances in endovascular interventions made angiography with embolisation the modality of choice for diagnosis and treatment. We presented the first report of a case of ruptured IPA pseudoaneurysm complicating a drug-induced acute pancreatitis that was successfully treated by transcatheter arterial embolisation. Despite its rarity, rupture of pseudoaneurysm due to drug-induced pancreatitis should be suspected and included in the differential diagnosis when associated with haemodynamic instability.

    Abstract Aneurysm or pseudoaneurysm formation is one of the vascular complications of Behcet disease. At present, the optimal treatment for the disease has not been established. The authors report a case of vasculo-Behcet disease (v-BD) with recurrent pseudoaneurysms in the left infrainguinal arteries (common femoral artery, superficial femoral artery, and popliteal artery), as well as thrombosis in the popliteal vein and posterior tibial vein. The patient underwent 3 rounds of surgery, but developed a new pseudoaneurysm several months after each surgery. Eventually, the patient was successfully treated with a combination of endovascular repair, using a fully covered stent graft, and prednisone. The pseudoaneurysm regressed without recurrence for more than 1 year. For v-BD, treatment with immunosuppressive therapy alone may not be sufficient to prevent the recurrence of pseudoaneurysms. For the endovascular treatment of pseudoaneurysms affecting the infrainguinal arteries in v-BD, a fully covered stent graft without oversizing is essential to prevent the recurrence of pseudoaneurysms.

    Carotid artery pseudoaneurysm is a rare condition, particularly in the paediatric population. Only about 30 cases of carotid artery aneurysms in infants have been published until now. This paper reports the case of a giant pseudoaneurysm of the left common carotid artery due to swallowed fish bone by an 8-year-old boy. This pseudoaneurysm was 5.5 cm transverse-diameter and resulted in severe respiratory distress. It was treated by resection and end-to-end anastomosis with satisfactory outcome after one-year follow-up. To the best of our knowledge, this is the largest carotid artery pseudoaneurysm ever described in children. PMID:26783485

    2015-01-01

    Pseudoaneurysms of the superficial temporal artery are an uncommon vascular lesion of the external carotid system and most often the result of blunt head trauma. The frequency of pseudoaneurysms of the superficial temporal artery developing after craniotomy is exceedingly low and only a few cases have been reported. We present a case of pseudoaneurysm of this type in a 45-year-old male who underwent craniotomy for excision of meningioma. One month postoperatively, the craniotomy flap exhibited an enormous diffuse pulsate swelling. The suspected diagnosis of pseudoaneurysm arising from superficial temporal artery was confirmed on angiography. Surgical excision was done and no recurrences of the tumor or aneurysm were noted on subsequent follow up. PMID:26501064

    Background: Dissecting giant pseudoaneurysm of the middle cerebral artery (MCA) is a rare lesion often presenting challenges to neurosurgical teams dealing with this specific pathology. Giant pseudoaneurysm originating from a dissecting distal segment of the MCA treated with aneurysm trapping under motor and sensitive evoked potential monitoring with a successful outcome is presented in the article followed by a brief discussion on the subject. Case Description: A case of a previously healthy young female patient admitted at the emergency room of Santa Paula Hospital with a history of a sudden headache and syncope, dysphasia, and Grade 4 right hemiparesis due to a large brain hemorrhage secondary to a 25 mm ruptured pseudoaneurysm originated from a distal left MCA dissecting segment is described. Because the patient risked neurological worsening, aneurysm was treated with parent and efferent vessel trapping technique and no changes on the sensitive and motor evoked potential (MEP) from baseline informed on this decision. Hemorrhage was completely drained after aneurysm was secured. Conclusion: Neurophysiological sensitive and MEP monitoring, on this specific case was a valuable tool and informed on the decision of trapping of this large vascular lesion. PMID:27127710

    We report a case of nontraumatic rupture of the lumbar artery that led to a pseudoaneurysm in the vertebral body and massive retroperitoneal to retropleural hematoma. The pseudoaneurysm was successfully treated by endovascular embolization. To our knowledge, idiopathic rupture of the lumbar artery has been reported in a limited number of cases and pseudoaneurysm formation in the vertebral body has not been presented in the literature. The etiology of hemorrhage has been discussed based on CT, MRI, and three-dimensional rotational angiography.

    We present a case of vertebral artery pseudoaneurysm after a posterior C1-C2 transarticular screw fixation procedure that was effectively treated with endovascular coil occlusion. Vertebral artery pseudoaneurysm complicating posterior C1-C2 transarticular fixation is extremely rare, with only one previous case having been reported previously. Endovascular occlusion is better achieved in the subacute phase of the pseudoaneurysm, when the wall of the pseudoaneurysm has matured and stabilized. Further follow-up angiographies are mandatory in order to confirm that there is no recurrence of the lesion.

    Summary Background: ankle arthroscopy increased its role in the diagnosis and treatment of pathology of the ankle since 1970s. Although the benefits are well established, ankle arthroscopy is associated with a definite risk of complications, especially neurological. The incidence rate of vascular complication after anterior ankle arthroscopy has been reported. Methods: we review the literature on vascular complications after anterior ankle arthroscopy especially pseudoaneurysm and a case report of a peronal artery pseudoaneurysm was reported. Conclusion: vascular complications after an anterior ankle arthroscopy are extremely rare but orthopaedic surgeons should be wary of this chance. Among vascular complications after an anterior ankle arthroscopy, peroneal artery pseudoaneurysm to our knowledge never has been described until now. PMID:25332946

    We report a case of a radial artery pseudoaneurysm complicating an incorrect puncture of a Brescia-Cimino hemodialysis fistula that was treated with percutaneous ultrasound-guided thrombin injection. The pseudoaneurysm recurred after the initial successful thrombin injection. With a second injection we obtained permanent pseudoaneurysm occlusion. Our case illustrates that this procedure is an effective treatment in this type of arteriovenous fistula complication. We compare this case with the only similar one we could find in the literature.

    An early diagnosis of popliteal artery pseudoaneurysm-a sequela of popliteal artery trauma-is difficult owing to its late presentation following total knee arthroplasty. The incidence of a popliteal artery pseudoaneurysm with a hematoma presenting only a peripheral nerve injury after total knee arthroplasty is also uncommon in the absence of common diagnostic features such as a pulsatile swelling with an audible bruit on auscultation. In the present report, we describe popliteal artery pseudoaneurysm following total knee arthroplasty. PMID:24944978

    Pseudoaneurysms of intercostal artery are very rare. All the published cases have been caused by trauma, either iatrogenic or otherwise. They can cause hemothorax, retroperitoneal hemorrhage or can present as pulsatile chest mass. Doppler ultrasound, contrast-enhanced CT and conventional angiogram can accurately diagnose this condition. All the reported cases have been treated by embolisation, stenting or surgery. We report an unusual case of intercostal artery pseudoaneurysm arising as a complication of corrosive poisoning presenting with hematemesis and treated by glue embolisation. The authors believe this to be the first case of intercostal artery pseudoaneurysm that is non-traumatic, complicating corrosive poisoning and presenting with hematemesis. PMID:25024522

    Pseudoaneurysm formation of the deep circumflex iliac artery (DCIA) after harvesting an anterior iliac bone graft for spinal fusion is reported herein. A 76-year-old man with cervical myelopathy underwent anterior cervical decompression and fusion with a left anterior iliac bone graft. A painful left inguinal mass was noted 1 month later. He was admitted to our emergency ward. Angiography of the left external iliac artery was performed which showed a pseudoaneurysm of the DCIA. Selective transarterial coil embolization of the artery was performed, and bleeding was arrested. In a review of the previous literature, only 1 pseudoaneurysm of the DCIA was reported to be associated with anterior iliac bone graft. In conclusion, vascular injury after anterior iliac bone harvesting is rare but can occur. Selective transarterial coil embolization is a prompt and effective solution. PMID:12350036

    A 29-year-old woman (gravida 1, para 1) had an uneventful first pregnancy and a delivery by emergency caesarean section at term. The caesarean section was complicated by a massive obstetric haemorrhage of 5000 ml. After closure, an immediate re-laparotomy was indicated due to heavy vaginal bleeding. The site of bleeding was identified as an extension of the uterine incision, and was sutured. She was stabilised by transfusion of blood and blood products in the intensive therapy unit, and discharged 5 days later. The patient was re-admitted 6 weeks later with brisk, painless vaginal bleeding, passing large clots from a well-contracted uterus. Her haemoglobin decreased from 11.8 to 7.8 g/dl overnight. In view of her history, an urgent CT angiogram was performed, which revealed the presence of a pseudo-aneurysm arising from the left uterine artery. This was successfully occluded by transarterial embolisation, obviating the need for further surgical exploration. PMID:22674937

    Pseudoaneurysm happens when the artery wall is injured and the blood is contained by the surrounding tissues with eventual formation of a fibrous sac communicating with the artery. We report a case of a 39-year-old man with inferior epigastric artery (IEA) pseudoaneurysm after paracentesis. The pseudoaneurysm was diagnosed by Doppler ultrasound and treated by surgical intervention regarding the patient’s underlying comorbidity. IEA false aneurysm must be included in the differential diagnosis during investigation of the cause of any swelling after paracentesis. Cirrhotic patients may be more prone to this complication because of thin rectus muscle that could not confine the hematoma. PMID:26557270

    Coil embolization to occlude the feeding artery of a pseudoaneurysm is an effective treatment to control hemoptysis. However, a feeding artery of the pseudoaneurysm may not be identified at pulmonary angiography, resulting in a failure to obtain embolization. We describe here two cases of a Rasmussen aneurysm that was successfully treated with percutaneous injection of thrombin (case 1) and N-butyl cyanoacrylate (case 2) under ultrasonographic and fluoroscopic guidance after failed transcatheter coil embolization.

    We report two patients with arteriovenous hemodialysis fistulas that were complicated by brachial artery pseudoaneurysms. Each pseudoanerysm was percutaneously thrombosed with an injection of thrombin, using techniques to prevent escape of thrombin into the native brachial artery. In one patient, an angioplasty balloon was inflated across the neck of the aneurysm during thrombin injection. In the second patient, thrombin was injected during ultrasound-guided compression of the neck of the pseudoaneurysm. Complete thrombosis of each pseudoaneurysm was achieved within 30 sec. No ischemic or embolic events occurred. This technique may be useful in treating pseudoaneurysms of smaller peripheral arteries.

    We report the case of a patient who developed an asymptomatic pseudoaneurysm in the left external iliac artery after transplant nephrectomy. The pseudoaneurysm most probably arose as a suture aneurysm from the external iliac artery after removal of the graft renal artery. Obviously we can not exclude the possibility it was a true aneurysm, although this seems much less likely. The pseudoaneurysm was detected during a routine CT scan and was treated interventionally with a stent-graft. One month later the asymptomatic patient underwent a vascular ultrasound examination including color Doppler, power Doppler, and B-flow as a routine control. An endoleak with collapse of the stent-graft was diagnosed. There was no evidence of stent infection. At a reintervention, the pseudoaneurysm was successfully treated using two uncovered Palmaz stents at the proximal and distal edge of the stent graft. Peri- and post-interventional ultrasound and CT angiography confirmed the exclusion of the aneurysm without an endoleak.

    Pseudoaneurysm of the superior gluteal artery (SGA) is very rare and the most common causes are blunt or penetrating pelvic traumas. Although pseudoaneurysm can be asymptomatic at the time of initial trauma, it can be symptomatic weeks, months, even years after initial trauma. We present a case of a ruptured superior gluteal artery pseudoaneurysm with hemorrhagic shock twenty days after a bomb injury in the Syria civil war. In addition, we review the anatomy of the SGA, clinical presentation and pitfalls of pseudoaneurysm, and imaging and treatment options. PMID:27239635

    We report two cases of acutely infected pseudoaneurysms of the iliac arteries, successfully treated with endovascular stent-grafting. Two patients underwent stent-graft treatment for erosive rupture of the iliac artery caused by surrounding infection. The first case is that of a 61-year-old man who had undergone Miles' operation for an advanced rectal cancer. Postoperatively, he developed intrapelvic abscess formation, from which methicillin-resistant Staphylococcus aureus was cultured, followed by rupture of the right external iliac artery. The second case is that of a 60-year-old man who had a pseudoaneurysm of the left common iliac artery, which was contiguous with a left psoas muscle abscess, from which Streptococcus agalactiae was cultured. Both patients were successfully treated with only a stent-graft and antibiotic therapy, and remained symptom-free 12 months and 10 months later. Although endovascular stent-grafting should not be considered standard therapy for infected aneurysms, our cases suggest that it can result in repair of infected aneurysms even in the uncontrolled active stage.

    Pancreatico-duodenal artery (PDA) pseudoaneurysms are rare vascular conditions with high mortality rates after rupture and they are frequently secondary to pancreatitis, surgery, trauma or infection. Due to the high risk of rupture and bleeding, it is mandatory to treat all pseudoaneurysms, regardless of their size or symptomatology. First option of treatment is open surgical repair, but it has high mortality rate, especially in hemodynamically unstable patients. In the recent years, percutaneous ultrasonography (US)- or computed tomography-guided thrombin injection was proposed as an alternative method for treating visceral aneurysms and pseudoaneurysms, but few reports described this therapy in case of peri-pancreatic pseudoaneurysms. We present a rare case of pseudoaneurysm of the PDA in a patient with no previous history of pancreatitis nor major surgery but with an occlusive lesion of the celiac axis. To the best of our knowledge this is the first reported case of PDA pseudoaneurysm successfully treated in emergency by single transabdominal US-guided injection of thrombin after failed attempts of percutaneous catheterization of the feeding vessel of the pseudoaneurysm.

The patient underwent emergent repair of the confluence of the right internal jugular, subclavian and brachiocephalic veins, and laparotomy secondary to compartment syndrome. Seven weeks later, with the pseudoaneurysm enlarged to 6 cm, it was repaired with combined access via the right common femoral artery and right brachial artery. The pseudoaneurysm was covered with a 7 mm x 8 cm fluency-covered stent graft and postdilated with a 7 mm x 4 cm balloon. Postoperatively, the patient had palpable pulses, occlusion of the pseudoaneurysm, and excellent blood flow into the arm. PMID:18583305

We describe a case of an 82-year-old lady, who presented 10 years following right shoulder joint replacement, with a sharply marginated erythematous cutaneous eruption over the right shoulder. Subsequent angiography revealed a pseudoaneurysm of the acromial branch of the thoracoacromial artery. Planned intervention was superseded by a further embolic episode, which prompted immediate percutaneous translumninal embolisation of the aneurysm.

    Postpartum hemorrhage is a major cause of maternal mortality. Though uncommon, uterine artery pseudoaneurysm can follow uterine dilatation and curettage (D + C) and needs to be considered in the differential diagnosis. This 30-year-old G1P1 woman presented with right upper quadrant pain and vaginal bleeding. She was afebrile but her white blood count was significantly increased (22.2 × 10(9) /L). One week prior, she had undergone a Cesarean delivery which was complicated by hemolysis, elevated liver enzymes, and low platelet count syndrome (HELLP), fetal dystocia, and chorioamnionitis. Uterine dilatation and curettage (D & C) and placement of a Bakri intrauterine balloon, performed for suspected retained products of conception, failed to control her postpartum bleeding. The patient wished to have a hysterectomy only as a last resort in order to preserve fertility. Emergency uterine artery angiography revealed a left uterine artery pseudoaneurysm and contrast extravasation. The patient was successfully treated with selective embolization. Computed tomography (CT) later revealed dehiscence of her uterine Cesarean section incision with an intra-abdominal fluid collection. This collection was drained. She also developed disseminated intravascular coagulopathy (DIC) syndrome as well as multiple pulmonary emboli which were both successfully treated. We discuss this unique case of uterine artery pseudoaneurysm with associated uterine dehiscence. PMID:22606544

    PurposeTo describe our experiences with treatment of visceral artery pseudoaneurysms (VAPA) by transcatheter coil embolization using an isolation technique and to propose indications for treating VAPA with this method.Materials and MethodsWe treated 37 patients with VAPA endovascularly: There were 15 pancreaticoduodenal arcade, 10 hepatic, 5 renal, 3 splenic, and 1 each left gastric, gastroepiploic, adrenal, and superior mesenteric artery pseudoaneurysms. Preprocedure computed tomography (CT) and/or angiographic studies confirmed the presence of VAPA in all 37 patients. Using the isolation technique, we embolized vessels at sites distal and proximal to the pseudoaneurysm.ResultsTranscatheter coil embolization with the isolation technique was technically successful in 33 (89%) of 37 patients, and angiogram confirmed the complete disappearance of the VAPA in 32 patients. No major complications occurred during the procedures. In a patient with a pancreaticoduodenal arcade artery pseudoaneurysm, we were unable to control hemorrhage. In 30 of 32 patients who recovered after transcatheter coil embolization using the isolation technique, follow-up CT scan showed no flow in VAPA; they survived without rebleeding. Two of the 32 patients (6%) with confirmed complete disappearance of VAPA on angiogram and CT scan obtained the day after the procedure manifested rebleeding during follow-up.ConclusionTranscatheter coil embolization using the isolation technique is an effective alternative treatment in patients with VAPA. In combination with coil embolization, the isolation technique is particularly useful in patients whose pseudoaneurysms present surgical difficulties.

    Sclerotherapy is commonly used to manage bleeding from oesophageal varices. In a patient with cirrhosis of the liver, sclerotherapy with bucrylate was followed by a pulmonary embolism and then by a decline in general health. A chest radiograph taken 5 months later disclosed a left perihilar opacity, surrounding and invading the pulmonary artery. Despite moderate fixation by positron emission tomography and inconclusive bronchoscopy findings, an upper left lobectomy was deemed in order. A left pulmonary artery pseudoaneurysm was found during the surgery. The pseudoaneurysm ruptured during dissection, requiring a left pneumonectomy. The pathological examination showed shredding of the left pulmonary artery, which contained foreign material. At points of contact with this material, destruction and severe polymorphic inflammation of the pulmonary parenchyma were noted. There was no evidence of tumour or infection. These findings strongly suggested an iatrogenic pulmonary artery pseudoaneurysm related to a bucrylate embolism through porto-systemic vascular shunts. We are not aware of previously reported cases.

    Ruptured hepatic artery pseudoaneurysm (HAP) generally leads to the hemobilia and can be diagnosed by endoscopy. This condition mostly occurs after an iatrogenic trauma. The management of the HAP is still a big challenge. Due to an increased rate of HAP cases over the last decade, appropriate management is necessary for the optimal outcomes achievement. Here, we report a 59-year-old woman presenting with hematemesis, melena, hematochezia, and epigastric pain. The CT scan of the abdomen showed intrahepatic biliay dilation with hypodense material, probably a clot inside it. Subsequently, the patient was transferred to an angiography unit. Celiac artery angiography demonstrated a right hepatic artery pseudoaneurysm, which subsequently embolized. PMID:27362248

    Intercostal artery pseudoaneurysms are extremely rare. We present a case of an intercostal artery pseudoaneurysm after median sternotomy that was treated by ultrasound-guided percutaneous thrombin injection. They are a potential source of complications, especially haemothorax, and treatment is mandatory. Different methods may be used for the confirmatory diagnosis of false aneurysms. Doppler ultrasound (DUS) and CT are the two most commonly used methods, but pseudoaneurysms have also been diagnosed by means of arteriography (AR), which enables endovascular treatment of the pseudoaneurysm in a single procedure. We used Doppler sonography alone, because this technique yielded a definitive diagnosis without the need for other complementary imaging modalities to treat the lesion. There are various possible treatments for lesions of this kind. Endovascular embolization is the commonly used treatment for intercostal pseudoaneurysm but also stent grafting has been described. Surgical aneurysmectomy with proximal ligation of the intercostal artery is an option described for the treatment of the pseudoaneurysm. To date only seven cases have been published in the literature. Our case is the only published instance of treatment of an intercostal artery pseudoaneurysm by direct percutaneous thrombin injection under sonographic guidance. PMID:19602496

    Splenic artery aneurysms (SAAs) are the third most frequent intra-abdominal aneurysm, following abdominal aorta and iliac artery aneurysms. SAAs are classified according to their involvement of arterial wall layers: true aneurysms involve all 3 layers (intima, media, and adventitia), and pseudoaneurysms involve only one or two. Herein we present a new case of giant pseudo SAA. A 65-year-old female patient with a pancreatic mass and iron deficiency was referred to our clinic for further investigation. Abdominal ultrasonography, contrast-enhanced CT and magnetic resonance imaging showed a lesion resembling a subcapsular hemangioma in the spleen, and aneurysmatic dilation of the splenic artery with a diameter of >5 cm. The large size of the aneurysm and the clinical findings were indications for surgical treatment. The patient underwent en bloc resection of the spleen, distal pancreas, and aneurysmatic segment of the splenic artery. The patient remains complication-free 2 months after the operation. Spontaneous rupture is the most important life-threatening complications of giant SAAs. Therefore, all symptomatic patients with SAA should be treated, as well as asymptomatic patients with lesions ≥2 cm, who are pregnant or fertile, have portal hypertension, or are candidates for liver transplantation. Despite advances in endovascular techniques, conventional abdominal surgery remains the gold standard for treatment. PMID:26595501

A covered stent was inserted percutaneously to exclude the APF and the pseudoaneurysm in a single procedure. The patient returned to our service after 21 months for a follow-up CT scan, which demonstrated the stent and the distal vasculature to be patent.

    Background: As carotid artery stenting becomes increasingly used, more complications are likely to occur. We present a case of Staphylococcus septicemia and pseudoaneurysm arising in the neck portion of the carotid artery after stenting. Case Description: A 51-year-old man was admitted with mild left hemiparesis. CT and MRI showed right hemisphere ischemia. Duplex Scan and MRA showed bilateral severe stenosis of the carotid arteries in the neck. A percutaneous angioplasty with stenting of the left carotid artery was performed. Two weeks after the procedure, he developed fever and swelling in the right leg and shoulder. An abscess, near where the groin had been punctured for the angioplasty was surgically drained. Blood samples were positive for S. aureus. After treatment the patient complained of a painful bulky pulsatile left cervical mass. Duplex scan and MRA showed a pseudoaneurysm of the left carotid artery. We excised the pseudoaneurysm and rebuilt the carotid artery with a saphenous vein graft. The postoperative period was uneventful, and the MRA revealed a patent saphenous graft. Conclusion: Mycotic pseudoaneurysm of the carotid artery is a rare complication of percutaneous angioplasty and stenting. Surgical treatment with saphenous vein graft is the treatment of choice.

    Visceral artery pseudoaneurysms are rare and only few cases have been reported. They are considered to be life threatening in case of rupture. Rapid treatment is mandatory and endovascular procedure is recommended as the treatment of choice. Occasionally, endovascular approach is difficult to achieve, owing to unusual vascular anatomy. Whenever it is the case, an alternative method has to be considered. We report the case of a jejunal artery pseudoaneurysm that required an access via collateral vessels to accomplish complete occlusion in a 34-year-old woman who presented with a sudden epigastric pain 14 days after a cephalic duodenopancreatectomy.

    Pseudoaneurysm resulting from hysteroscopic myomectomy is a rare clinical situation, and interventional radiologists are not traditionally involved in the management. To our knowledge, endovascular treatment of a pseudoaneurysm resulting from hysteroscopic myomectomy has not yet been reported in the English-language literature. Here, two such cases are reported, including one of a woman who later became pregnant. The case is unique because little is known about the influence of unilateral coil embolization of the uterine artery on fertility.

    Transcatheter arterial embolization is becoming the therapy of choice for controlling obstetric hemorrhage, affording the ability to control persistent bleeding from pelvic vessels while avoiding the morbidity of surgical exploration. The clinicians are left with little choice if pelvic hemorrhage continues after hysterectomy and ligation of anterior division of both internal iliac arteries. We present one such case of intractable post-obstetric hysterectomy hemorrhage in which an ovarian artery pseudoaneurysm was diagnosed angiographically and successfully embolized, highlighting the role of transcatheter embolization.

    Mycotic pseudoaneurysm of the pulmonary artery that ruptures during necrotizing pneumonia is a rare entity that is often fatal. Traditionally it has been treated with open thoracotomy and resection of both the aneurysm and the lobe in which the aneurysm is located. In this report, we describe the radiological findings and transcatheter coil embolization of a mycotic pulmonary pseudoaneurysm in a 6-month-old female infant. We also describe the subsequent morphologic changes observed on follow-up computed tomography after 9 months of embolization.

    Epistaxis is a frequent health problem and the most common cause of emergency in otorhinolaryngology practice. In this report, a case of a 26-year-old patient with intractable epistaxis after endoscopic sinus surgery was presented. The epistaxis began at the fourth postoperative day and was unresponsive to endoscopic cauterization and anterior and posterior nasal packing. On angiographic investigation, a pseudoaneurysm of the sphenopalatine artery was detected and treated with microcatheter embolization. This is the second case of postoperative sphenopalatine pseudoaneurysm as a complication of endoscopic sinus surgery in the literature. PMID:24621700

    Purpose: Our purpose was to evaluate iatrogenic renal pseudoaneurysms, endovascular treatment, and outcomes. Methods: This retrospective study (2003-2011) reported the technical and clinical outcomes of endovascular therapy for renal pseudoaneurysms in eight patients (mean age, 46 (range 24-68) years). Renal parenchymal loss evaluation was based on digital subtraction angiography and computed tomography. Results: We identified eight iatrogenic renal pseudoaneurysm patients with symptoms of hematuria, pain, and hematoma after renal biopsy (n = 3), surgery (n = 3), percutaneous nephrolithotomy (n = 1), and endoscopic shock-wave lithotripsy (n = 1). In six patients, the pseudoaneurysms were small-sized (<20 mm) and peripherally located and were treated solely with coil embolization (n = 5). In one patient, coil embolization was preceded by embolization with 500-700 micron embospheres to control active bleeding. The remaining two patients had large-sized ({>=}50 mm), centrally located renal pseudoaneurysms treated with thrombin {+-} coils. Technical success with immediate bleeding cessation was achieved in all patients. There were no procedure-related deaths or complications (mean follow-up, 23.5 (range, 1-67) months). Conclusions: Treatment of renal pseudoaneurysms using endovascular approach is a relatively safe and viable option regardless of location (central or peripheral) and size of the lesions with minimal renal parenchymal sacrifice.

    Traumatic pseudoaneurysm of the axillary artery combined with brachial plexus injury is extremely rare. The factors that influence the symptoms and functional recovery related to this condition are unclear. Nine patients who had sustained this trauma were surgically treated at our unit between June 1999 and November 2010. The cause of trauma, symptoms, signs and examinations of neurological and vascular deficits, and the surgical findings of the involved nerves and vessels were recorded in detail. The functional recovery of vessels and nerves, as well as the extent of pain, were evaluated, respectively. The average length of patient follow-up was 4.5 years (range, 24 months to 11.3 years). After vessel repair, whether by endovascular or operative treatment, the distending, constant, and pulsating pain was relieved in all patients. Furthermore, examination of the radial artery pulse on the repaired side appeared normal at last follow-up. All patients showed satisfactory sensory recovery, with motor recovery rated as good in five patients and fair in four patients. The symptom characteristics varied with the location of the damage to the axillary artery. Ultrasound examination and computed tomography angiography are useful to evaluate vascular injury and provide valuable information for operative planning. Surgical exploration is an effective therapy with results related to the nerve injury condition of the brachial plexus. PMID:25412426

    Pseudoaneurysm of the internal maxillary artery is a rare occurrence. A well-organized pulsatile mass that develops after a traumatic event indicates a pseudoaneurysm. Such lesions are commonly misdiagnosed for an abscess or a hematoma. Pulsations and audible bruit are diagnostic features of an aneurysm. Rupture of such false aneurysms cause significant morbidity. Management is either surgical resection or embolization. Endovascular embolization is indicated in deep seated lesions or lesions with high morbidity. Though surgical resection is an invasive procedure, it is considered to be an alternative to embolization. PMID:25593875

    Dissection of the cervical segment of the internal carotid artery may occur spontaneously or after trauma. We report the management of a 53-year-old right-handed man with progressive dizziness and neck pain 6 weeks after a motor vehicle collision. The clinical and neurologic examinations were normal. The CT scan led to the diagnosis of a pseudoaneurysm of the right internal carotid artery near the skull base. We successfully treated this post-traumatic lesion with a covered stent. The patient underwent the endovascular procedure under general anesthesia and transcranial Doppler monitoring. No neurologic event was observed. Obliteration of the pseudoaneurysm with preservation of the carotid artery was achieved. The patient was discharged from the hospital 72 hr later with no complications. Clinical and imaging follow-up at 6 months was unremarkable.

    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

    Background: Traumatic pseudoaneurysms of the middle meningeal artery (MMA) are rare, associated with skull fractures, and have a high mortality rate. When they rupture, MMA pseudoaneurysms frequently cause epidural hematomas and occasionally ipsilateral subdural or subarachnoid hemorrhage. Isolated intraparenchymal hemorrhage has also been reported. Case Description: A 54-year-old female who suffered a loss of consciousness resulting in a fall presented with a Glasgow Coma Scale of 7t. Imaging demonstrated a right subdural hematoma (SDH) with midline shift, left skull fracture overlying the left MMA, and left temporal lobe intraparenchymal hematoma extending to the surface. The patient underwent a right craniectomy with evacuation of the SDH, and the preoperative computed tomographic angiography revealed abnormal dilation of the left MMA consistent with a pseudoaneurysm. The pseudoaneurysm was treated with endovascular treatment, and the intraparenchymal hematoma was treated conservatively. Her recovery was uneventful, and she received a cranioplasty 3 months after the decompression. Conclusions: The presence of a fracture over the MMA and intraparenchymal hematoma should prompt suspicion for a traumatic pseudoaneurysm. Pseudoaneurysms of the MMA can cause catastrophic bleeding, and prompt treatment is necessary. Endovascular embolization is an effective method that decreases the hemorrhage risk of MMA pseudoaneurysms. PMID:26862457

    Behçet's disease is a systemic vasculitis of unknown etiopathogenesis. Arterial events such as pseudo-aneurysms are rare and may be the mode of occurrence of the disease. These pseudo-aneurysms tend, regardless of size, to progress rapidly to life-threatening rupture. We report two cases of arterial pseudo-aneurysms that ruptured. Treatment consisted of surgical repair in one case and arterial ligation in the other; the postoperative course was uneventful in both cases. PMID:26947054

    Introduction Pseudoaneurysms occur when there is a partial disruption in the wall of a blood vessel, causing a hematoma that is either contained by the vessel adventitia or the perivascular soft tissue. Presentation of case A 32-year-old male presented to the emergency department presented with comminuted fractures in the left zygoma, ethmoids, and the right ramus of the mandible following a gunshot wound. The patient underwent open reduction of his fractures and the patient was discharged on the eighth day after the trauma. Thirteen days after the discharge and 21 days after the gunshot wound, the patient returned to the ER due to heavy nasopharyngeal bleeding that compromised the patency of the patient’s airways and caused hemodynamic instability. Arteriography of the facial blood vessels revealed a pseudoaneurysm of the maxillary artery. Endovascular embolization with a synthetic embolic agent resulted in adequate hemostasis, and nine days after embolization the patient was discharged. Discussion The diagnosis of pseudoaneurysm is suggested by history and physical examination, and confirmed by one of several imaging methods, such as CT scan with contrast. Progressive enlargement of the lesion may lead to several complications, including rupture of the aneurysm and hemorrhage, compression of adjacent nerves, or release of embolic thrombi. Conclusion This case reports the long-term follow up and natural history of a patient with a post-traumatic pseudoaneurysm of the internal maxillary artery and the successful use of endovascular embolization to treat the lesion.

    Background: Traumatic pseudoaneurysm of the internal carotid artery (ICA) is an uncommon but serious complication, and difficult to repair surgically. Minimally invasive endovascular treatment of traumatic injuries of the ICA with a stent graft has become increasingly popular over the past decade. The efficacy of the stent graft appears satisfactory, but most if not all reported studies have involved small patient cohorts (less than 10) with short follow-up periods (less than 3 years). Methods: In this prospective study, 13 patients with traumatic pseudoaneurysm of the ICA were recruited from June 2008 to June 2012. All the patients were examined using whole-brain cerebral angiography and followed up for as long as five years. Willis intracranial vascular stent grafts, manufactured by Shanghai Microport, were chosen as embolism material. Results: All 13 patients achieved good clinical outcome. Pseudoaneurysm recurred in one patient and this patient was treated by balloon occlusion of the parent artery. No patient suffered recurrent bleeding or death. Conclusion: Based on the outcomes of this relatively large cohort and long follow-up period, we believe that stent graft is an optimal therapy for patients with traumatic pseudoaneurysms of the ICA.

    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

    Objectives: Mycotic pseudoaneurysms of the extracranial internal carotid artery are rare, and their management often represents a challenge, but treatment is necessary due to the high risk of rupture and distal brain embolization. Systemic antibiotics associated with open surgical excision of the infected tissues and carotid reconstruction using autologous grafts are the treatment of choice. The use of endovascular techniques still remains controversial in infective fields; however, it can be an attractive alternative in high-risk patients or more often as a “temporary” solution to achieve immediate bleeding control for a safe surgical reconstruction. Methods: We discuss the unusual case of an extracranial right internal carotid artery mycotic pseudoaneurysm following methicillin-resistant Staphylococcus aureus infection, in a patient with poor general conditions. Results and Conclusion: The lesion was successfully treated using a hybrid endovascular and surgical procedure. PMID:27489662

    Visceral artery pseudoaneurysms occur mostly as a result of inflammation and trauma. Owing to high risk of rupture, they require early treatment to prevent lethal complications. Knowledge of the various approaches of embolization of pseudoaneurysms and different embolic materials used in the management of visceral artery pseudoaneurysms is essential for successful and safe embolization. We review and illustrate the endovascular, percutaneous and endoscopic ultrasound techniques used in the treatment of visceral artery pseudoaneurysm and briefly discuss the embolic materials and their benefits and risks.

    2014-05-01

    Pseudoaneurysms rarely occur as a serious complication following incomplete hemostasis of an arterial puncture site. As a result of the increase in diagnostic and therapeutic angiography, the frequency of iatrogenic pseudoaneurysm has increased as well. Iatrogenic pseudoaneurysms associated with angiographic catheterization occur most commonly in the common femoral artery. Here we report a case of iatrogenic superficial external pudendal artery (SEPA) pseudoaneurysm following cardiac catheterization, which was diagnosed with Doppler ultrasound (US) and multidetector computed tomographic angiography (MDCTA) before Doppler US-guided compression therapy. To the best of our knowledge, iatrogenic SEPA pseudoaneurysm, which is an unusual vessel location for pseudoaneurysm occurrence, has not been reported in the literature. In patients in whom anticoagulant-thrombolytic therapy or therapeutic catheterization with larger sized sheath is planned, determination of the precise localization of arterial puncture site is important for the prevention of iatrogenic pseudoaneurysm development. Arterial puncture guided with Doppler US might reduce complications. When suspected, MDCTA is useful in the diagnosis and demonstration of iatrogenic pseudoaneurysms. Treatment of US-guided compression should be the first choice for iatrogenic pseudoaneurysms. Interventional radiologists and cardiologists should have enough experience about the catheterization complications and their treatment in order to decrease the morbidity and mortality related to the intervention.

    We report an unusual pathological entity of a pseudoaneurysm of the right hepatic artery, which developed two years after the resection of a type II hilar cholangiocarcinoma and secondary to an excessive skeletonization for regional lymphadenectomy and neoadjuvant external-beam radiotherapy. After a sudden and massive hematemesis, a multidetector computed tomographic angiography (MDCTA) showed a hepatic artery pseudoaneurysm. Angiography with embolization of the pseudoaneurysm was attempted using microcoils with adequate patency of the hepatic artery and the occlusion of the pseudoaneurysm. A new episode of hematemesis 3 wk later revealed a partial revascularization of the pseudoaneurysm. A definitive interventional radiological treatment consisting of transarterial embolization (TAE) of the right hepatic artery with stainless steel coils and polyvinyl alcohol particles was effective and well-tolerated with normal liver function tests and without signs of liver infarction.

    Hepatic artery pseudoaneurysms (HAP) are uncommon, occurring mostly as a complication of trauma (accidental or iatrogenic). Liver abscess rarely causes HAP and multiple HAP associated with cholangitic abscesses have not been reported in the literature. We present a patient of acute necrotizing pancreatitis with stent block cholangitis and multiple cholangitic abscesses who developed hemorrhagic output through drainage catheter in the liver abscess. A multiphasic CT angiography demonstrated three HAP, which were treated with a combination of endovascular coil embolization and percutaneous thrombin injection. The fact that cholangitic abscesses may be associated with pseudoaneurysms should not be neglected, considering the potentially catastrophic complication and relatively easy radiological management. CT angiography permits accurate diagnosis and lays down the roadmap for endovascular procedures. PMID:27081232

    Burrows, V; Zayyan, K S; Harding, J

    2015-01-01

    Supracolic peri-pancreatic visceral pseudoaneurysms combine the challenges of difficult location for open surgical repair with unpredictable risk of fatal exsanguination. Endovascular embolisation is a well-established method of safely decompressing these lesions using a variety of thrombogenic agents. A single catheter technique is commonly employed to achieve this outcome. However, there is also a risk of iatrogenic rupture during these procedures as a result of occlusion of one vessel allowing pressure to rise through any other vessel(s). Thus a thorough understanding of the flow dynamics prior to and during occlusion is essential for safe decompression. We report the adaptation of dual arterial catheter technique in treating these lesions in an 80-year old man with a large, leaking peripancreatic visceral pseudo-aneurysm. Our technique of alternating between intervention and observation of effect allows greater control of the potentially unpredictable haemodynamic situation. PMID:26158256

    In this article we present a fatal case of a ruptured intercostal artery pseudoaneurysm that occurred a number of years after an incident in which the patient suffered a blunt-trauma injury. A long interval between blunt trauma and this type of fatality has rarely been reported. This case discusses a 49-year-old woman who was found dead at her home by her husband and was referred for autopsy because the cause of death was uncertain. Her past medical history was unknown; however, it was learned that she had a bicycle accident 4 years previously and had sustained injuries to the left side of her body. During the autopsy, healed fractures in the bones of the left lower rib cage and a large amount of blood in the left thorax were observed. Furthermore, a hematoma, containing a small rupture was found in the left tenth intercostal space adjacent to the thoracic vertebrae. Histological examinations showed that the wall of the left tenth intercostal artery was ruptured, with recent blood clots including fibrin. Additionally, in the lesion where the tunica adventitia was disrupted, the dissecting cavity was filled with blood. We concluded that the woman died of hemorrhagic shock resulting from a ruptured intercostal artery pseudoaneurysm that formed as a result of the injury incurred from the bicycle accident 4 years before.

    Subclavian artery pseudoaneurysm and occlusion in young patients are usually post-traumatic. We report the case of a 33-year-old diabetic woman with subclavian artery occlusion and pseudoaneurysm formation caused by pulmonary mucormycosis infection. The patient presented with diabetic ketoacidosis, Horner's syndrome, and absent left arm pulses. A cystic lesion of the left lung apex was found by imaging, was surgically resected, and was histologically diagnosed as mucormycosis infection. Magnetic resonance angiography depicted a left subclavian artery pseudoaneurysm and occlusion adjacent to the mucormycosis lesion. To protect against thromboembolic complications and rupture, the pseudoaneurysm was embolized with coils. The patient is clinically well 1 year after the intervention with no perfusion of the pseudoaneurysm.

    Objective. To review the literature concerning the management with placement of covered stent-grafts of traumatic pseudoaneurysms of the extracranial internal carotid artery (ICA) resulting from penetrating craniocervical injuries or skull base fractures. Method. We have reviewed, from the Medline database, all the published cases in the English literature since 1990 and we have added a new case. Results. We identified 20 patients with traumatic extracranial ICA pseudoaneurysms due to penetrating craniocervical injuries or skull base fractures who had been treated with covered stent-graft implantation. Many discrepancies have been ascertained regarding the anticoagulation therapy. In 3 patients the ICA was totally occluded in the follow-up period, giving an overall occlusion rate 15%. No serious complication was reported as a result of the endovascular procedure. Conclusion. Preliminary results suggest that placement of stent-grafts is a safe and effective method of treating ICA traumatic pseudoaneurysms resulting from penetrating craniocervical injuries or skull base fractures. The immediate results are satisfactory when the procedure takes place with appropriate anticoagulation therapy. The periprocedural morbidity and mortality and the early patency are also acceptable. A surveillance program with appropriate interventions to manage restenosis may improve the long-term patency.

    Medical ultrasound imaging with Doppler plays an essential role in the diagnosis of vascular disease. This study intended to review the clinical use of “to-and-fro” waveform at duplex Doppler ultrasonography (DDU) in the diagnosis of pseudoaneurysms in the arterial vessels of upper and lower extremities, abdominal aorta, carotid and vertebral arteries as well as to review our personal experiences of “to-and-fro” waveform at DDU also. After receiving institutional review board approval, an inclusive literature review was carried out in order to review the scientific foundation of “to-and-fro” waveform at DDU and its clinical use in the diagnosis of pseudoaneurysms in various arterial vessels. Articles published in the English language between 2000 and 2013 were evaluated in this review study. Pseudoaneurysms in arterial vessels of the upper and lower extremities, abdominal aorta, carotid and vertebral arteries characterized by an extraluminal pattern of blood flow, which shows variable echogenicity, interval complexity, and “to-and-fro” flow pattern on color Doppler ultrasonography. In these arterial vessels, Duplex ultrasonography can demonstrate the degree of clotting, pseudoaneurysm communication, the blood flow patterns and velocities. Spectral Doppler applied to pseudoaneurysms lumen revealed systolic and diastolic turbulent blood flow with traditional “to-and-fro” waveform in the communicating channel. Accurate diagnosis of pseudoaneurysm by spectral Doppler is based on the documentation of the “to-and-fro” waveform. The size of pseudoaneurysm determines the appropriate treatment approach as surgical or conservative. PMID:26029351

    Renal artery anastomotic pseudoaneurysms, an uncommon complication of transplantation, may result in aneurysm rupture and loss of allograft. We report the case of 50-year-old female with back pain 3 weeks post renal transplantation. CT scan revealed transplant renal artery anastomotic pseudoaneurysm arising from anastomosis of two renal arteries joined together to form a single renal artery that was joined to the aorta. Successful endovascular treatment was achieved with covered stents, resulting in preserved renal function. Follow-up ultrasound at one-day post procedure and CT at 2 months revealed satisfactory renal perfusion with no pseudoaneurysm. Endovascular treatment of transplant renal artery pseudoaneurysms with covered stent and ostial flare balloon technology may be preferred in patients with extensive prior pelvic surgery, as illustrated in this case.

    A true aneurysm is defined as an enlargement of an artery resulting in a diameter more than 1.5 times the anatomic size. It can be fusiform when it covers the entire perimeter of the vessel, or saccular when it bulges on one side of the artery. The pseudoaneurysm is a pulsating encapsulated haematoma in communication with the lumen of the ruptured vessel,which affects the the intima and the media and which is stopped from developing by the adventitia and the surrounding connective tissue. Geographically, aneurysm can be broadly divided into intracranial and extracranial types.While the neurosurgeon manages the intracranial types, the vascular surgeon manages the extracranial types. Vascular surgeons also do divide the extracranial types into central (abdominal-aorto-iliac, thoracic including ascending, transverse aortic arch and descending), peripheral (extremities) and visceral (splanchnic arteries). Splanchnic artery aneurysm includes the coeliac, superior mesenteric, inferior mesenteric arteries including their branches. Of all intra-abdominal aneurysms, only around 5% are due to the splanchnic arteries,which could be either true or pseudo. The prevalence has been estimated at 0.1-0.2%. PMID:27487600

    Intercostal artery pseudoaneurysm is an extremely unusual condition, with less than 10 reported cases to our knowledge. Most of them have been associated with surgical interventions or blunt thoracic trauma. The bleeding risk in this kind of lesions is considerable, the majority of them presenting as haemothorax. We present a case of an intercostal artery pseudoaneurysm detected after a blunt thoracic trauma in a patient with signs of acute bleeding. The identification of a small artery pseudoaneurysm as the cause of haemothorax requires knowledge of this possible aetiology as well as detailed attention to the CT technique. Embolisation is considered to be the first therapeutic method in the management of a ruptured pseudoaneurysm. To reduce the risk of failure, the anatomic features and adjacent vessels providing collateral branches must be studied and embolised if needed, with important attention to collateral blood supply arising from the musculophrenic and anterior intercostal arteries.

    A 25 year old male was admitted with features of life threatening renal haemorrhage after undergoing open nephrolithotomy for a staghorn calculus of the right kidney. CECT abdomen and selective renal angiography revealed a 2.5 × 3.0 cm pseudoaneurysm arising from the lower segmental branch of right renal artery, leaking into retroperitoneal space. After an initial failed attempt of transcatheter embolization with N-butyl cyanoacrylate (NBCA) and 10% lipiodol mixture, the pseudoaneurysm was successfully ablated with absolute alcohol. Our case demonstrates that absolute alcohol ablation is a safe and effective modality for controlling haemorrhage from an iatrogenic renal artery pseudoaneurysm. PMID:25634415

    Post-pancreatitis pseudoaneurysms are not uncommon. They have a high associated mortality due to a propensity to rupture. Current standards of treatment advocate immediate intravascular interventions. We describe two cases of alcohol-related post-acute pancreatitis pseudoaneurysms arising from the second-order branches of the superior mesenteric artery (SMA) that were endoluminally inaccessible. Both cases were successfully treated with percutaneous thrombin injection into the pseudoaneurysm sac under ultrasound guidance. We suggest that endoluminally inaccessible pseudoaneurysms that are percutaneously accessible can be expeditiously treated with percutaneous thrombin injection. Further, due to the efficaciousness of this procedure, it could be considered as a first-line minimally invasive therapeutic option. PMID:26590924

    Large cerebral aneurysms of the basilar apex are difficult to treat. Recently, endovascular treatment has mitigated much of the morbidity associated with treating these lesions. However, the morphology of aneurysms of the vertebrobasilar system can preclude endovascular treatment. Rapid ventricular pacing (RVP) facilitates open surgical treatment of cerebral aneurysms. It can assist in reducing the pressure of the neck of the aneurysm, allowing safe application of a clip. The authors present a case of a pediatric patient who developed a basilar artery pseudoaneurysm that required surgery. Given the large size of the aneurysm, RVP was performed, allowing the surgeons to dissect the dome of the aneurysm from the surrounding tissue and pontine perforating branches away from the lesion to safely clip the lesion. The patient had an uneventful recovery. To the authors' knowledge, this represents the first known case of RVP to aid in basilar artery clip occlusion in a pediatric patient. PMID:25745950

    PurposeTo assess the role and effectiveness of percutaneous arterial embolization (TAE) in patients with hemodynamic instability due to hypovolemic shock secondary to ruptured splanchnic artery pseudoaneurysms (SAPA).Materials and MethodsSeventeen patients (11 men, 6 women; mean age, 53 years) with hemodynamic instability (systolic blood pressure <90 mmHg) due to hypovolemic shock secondary to ruptured SAPA were treated by TAE. Clinical files, multidetector row computed tomography angiography, and angiographic examinations along with procedure details were reviewed.ResultsSeventeen SAPAs were present, predominantly located on gastroduodenal or pancreatic arteries (9/17; 53 %). Angiography showed extravasation of contrast medium from SAPA in 15/17 patients (88 %). Technical success rate of TAE was 100 %. TAE was performed using metallic coils in all patients (100 %), in association with gelatin sponge in 5/17 patients (29 %). TAE allowed controlling the bleeding and returning to normal hemodynamic status in 16/17 patients (94 %). In 1/17 patient (6 %), surgery was needed to definitively control the bleeding. The mortality and morbidity rate of TAE at 30 days were 0 and 12 %, respectively. Morbidity consisted in coil migration in 1/17 patient (6 %) and transient serum liver enzyme elevation in 1/17 patient (6 %).ConclusionTAE is an effective and safe treatment option for ruptured SAPA in hemodynamically unstable patients, with a success rate of 94 %. Our results suggest that TAE should be the favored option in patients with hemodynamic instability due to ruptured SAPA.

    INTRODUCTION Pseudoaneurysm of the cystic artery is very rare. In the majority of cases it has been reported as a post-operative complication of laparoscopic cholecystectomy, however it has also been associated with the presence of acute cholecystitis or pancreatitis. When these pseudoaneurysms rupture they can lead to intraperitoneal bleeding, haemobilia and upper gastrointestinal haemorrhage. Radiological as well as open surgical approaches have been described for control of this rare pathology. PRESENTATION OF CASE We report the laparoscopic surgical management of an incidental, unruptured cystic artery pseudoaneurysm in a patient presenting with acute cholecystitis. DISCUSSION Cystic artery pseudoaneurysm is a rare entity and as such there is no consensus on the clinical management of this condition. A variety of treatment strategies have been reported in the literature including radiological selective embolisation and coiling, open cholecystectomy with ligation of the aneurysm, or a two-step approach involving radiological management of the pseudoaneurysm followed by an elective cholecystectomy. CONCLUSION In this report we have demonstrated that laparoscopic management of a cystic artery pseudoaneurysm with simultaneous laparoscopic cholecystectomy is feasible and safe. This avoids multiple invasive procedures and decreases morbidity associated with open surgery. PMID:26291047

    An infected pseudoaneurysm of the right common femoral artery in a 69-year-old patient receiving methotrexate therapy was confirmed to have been caused by Mycobacterium tuberculosis. After surgical excision of the aneurysm and revascularization using femoral vein, cutaneous manifestations of M tuberculosis infection in the foot complicated the course. We hypothesized that methotrexate may have triggered the reactivation of dormant tuberculosis in this patient. Because extrapulmonary tuberculous pseudoaneurysms are clinically similar to other types of infected pseudoaneurysm, M tuberculosis infection should always be suspected during the initial diagnosis. We propose that mycobacterial cultures should be routine when initial cultures and Gram stain are negative. PMID:16950450

    We report an unusual case of a pseudoaneurysm of the superior gluteal artery as a complication of bone marrow biopsy. A 51-year-old man presented with sciatic pain and foot drop after undergoing bone marrow biopsy and was initially diagnosed as having degenerative disc disease based on his past medical history. Pelvic magnetic resonance imaging (MRI) revealed a large heterogeneous mass suggestive of a neurogenic tumor, but pulsatile blood was instead encountered during computed tomography (CT)-guided needle biopsy. Subsequent workup established the diagnosis of a superior gluteal artery pseudoaneurysm, which was treated with coil embolization, followed by surgical evacuation of the hematoma, which relieved his sciatic pain. However, the patient continues to have a persistent foot drop. Gluteal artery pseudoaneurysms are exceedingly uncommon but should be considered in the workup of a patient with gluteal pain or sciatic nerve palsy following trauma or medical procedures in the gluteal region.

    Vascular injury resulting in pseudoaneurysm formation in the plantar aspect of the foot is an uncommon injury after trauma. Such injuries are more often reported in the lateral plantar artery rather than the medial plantar artery, most likely because of its more superficial location. Traditional modalities in diagnosis have included ultrasound and digital subtraction angiography. We present a case of traumatic pseudoaneurysm of the lateral plantar artery following a foot laceration. Diagnosis was made by the use of high-resolution, time-resolved contrast-enhanced 3D magnetic resonance angiography, also referred to as “TRICKS” (time-resolved imaging of contrast kinetics). This technique provided high spatial resolution for the arterial anatomy as well as temporal resolution which allowed better delineation of the hemodynamic characteristics of the pseudoaneurysm.

A 21-year-old man referred to the Department of Oral and Maxillofacial Surgery with limited mouth opening and left preauricular swelling for more than 40 days after a traffic accident injury. He had received mandibulomaxillary fixation in the emergency department. Computed tomography showed left mandibular condylar fracture, and digital subtraction angiography confirmed left superficial temporal artery pseudoaneurysm. Endovascular embolization of the left external carotid artery was performed, followed by excision of the traumatic pseudoaneurysm and open reduction internal fixation of the left condylar fracture. Six months after treatment, the patient can open his mouth to approximately 35 mm and showed no swelling in the left preauricular region. PMID:23851869

    To describe when and how to perform endovascular embolization of aortic branch artery pseudoaneurysms associated with type A and type B intramural hematoma (IMH) involving the descending thoracic and abdominal aorta (DeBakey I and III) that increased significantly in size during follow-up. Sixty-one patients (39 men; mean {+-} standard deviation age 66.1 {+-} 11.2 years) with acute IMH undergoing at least two multidetector computed tomographic examinations during follow-up for 12 months or longer were enrolled. Overall, 48 patients (31 men, age 65.9 {+-} 11.5) had type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III). Among the 48 patients, 26 (54 %; 17 men, aged 64.3 {+-} 11.4 years) had 71 aortic branch artery pseudoaneurysms. Overall, during a mean follow-up of 22.1 {+-} 9.5 months (range 12-42 months), 31 (44 %) pseudoaneurysms disappeared; 22 (31 %) decreased in size; two (3 %) remained stable; and 16 (22 %) increased in size. Among the 16 pseudoaneurysms with increasing size, five of these (three intercostal arteries, one combined intercostobronchial/intercostal arteries, one renal artery), present in five symptomatic patients, had a significant increase in size (thickness >10 mm; width and length >20 mm). These five patients underwent endovascular embolization with coils and/or Amplatzer Vascular Plug. In all patients, complete thrombosis and exclusion of aortic pseudoaneurysm and relief of back pain were achieved. Aortic branch artery pseudoaneurysms associated with type A and type B IMH involving the descending thoracic and abdominal aorta (DeBakey I and III) may be considered relatively benign lesions. However, a small number may grow in size or extend longitudinally with clinical symptoms during follow-up, and in these cases, endovascular embolization can be an effective and safe procedure.

    Mycotic false aneurysm caused by local arterial injury from attempted intravenous injections in drug addicts remains a challenging clinical problem. The continued increase in drug abuse has resulted in an increased incidence of this problem, particularly in high-volume urban centres. In the drug-abusing population, mycotic arterial pseudoaneurysms most often occur because of missed venous injection and are typically seen in the groin, axilla, and antecubital fossa. Mycotic aneurysms may lead to life-threatening haemorrhage, limb loss, sepsis, and even death. Any soft-tissue swelling in the vicinity of a major artery in an intravenous drug abuser should be suspected of being a false aneurysm until proven otherwise and should prompt immediate referral to a vascular surgeon for investigation and management. We report a case of rupturing mycotic pseudoaneurysm of the left common femoral artery treated by surgical resection followed by vessel reconstruction with autologous material. Unfortunately, at the time of discharge a sudden leakage from the vein graft anastomosis occurred, with subsequent massive bleeding, and required emergent endovascular covered stenting. To the best of our knowledge, this is the first reported case of femoral artery bleeding in a drug abuser treated by stent graft placement.

    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.

    A 71-year-old man affected by cardio- and cerebrovascular disease experienced an accidental fall and trauma to the fronto-temporal area of the head. A few weeks later a growing mass appeared on his scalp. A diagnosis of superficial temporal artery pseudoaneurysm was made following CT and color Doppler ultrasound. His clinical condition favoured a conservative approach by ultrasound-guided compression and subsequent surgical resection. A conservative approach should be considered the treatment of choice in critically ill patients affected by superficial temporal artery pseudoaneurysm.

    Central venous catheterization is routinely required in a wide range of clinical situations such as hemodynamic monitoring, delivery of blood products and drugs, hemodialysis, total parental nutrition, and management of perioperative fluids. Pseudoaneurysms account for 4% of all innominate artery aneurysms. Clinical presentation may include airway and neurological compression, chest pain, mediastinal syndrome, upper limb ischemia, and hemodynamic instability. We report what we believe is the first documented case of a successful endovascular stent-graft repair of an innominate artery iatrogenic pseudoaneurysm. PMID:21193466

    We report the first case of endovascular covered stent implantation for the treatment of a large pulmonary artery pseudoaneurysm (PAPA) following a right thoracic gunshot wound. After resuscitation and hemodynamic stabilization, a CT angiography was performed to analyze the neck size of the PAPA and its position relative to the branches of the parent artery. Covered stent implantation with additional coil embolization was successfully performed. At the 4-year follow-up, the stents remained patent and there was neither pseudoaneurysm recurrence nor treatment-related complication. PMID:26662074

    Iatrogenic cavernous carotid pseudoaneurysms are a special group among other intracranial aneurysms. They can occur during the dissection phase of the surgery if the tumor encases a vessel. Complications of their rupture as hemorrhage or stroke are life threatening. Early recognition and treatment is mandatory to avoid catastrophic sequelae. We present the successful diagnosis and endovascular treatment of a postoperative cavernous carotid pseudoaneurysm following radical cavernous sinus resection. PMID:27330923

    This case report describes a traumatic pseudoaneurysm arising from the right V4 segment of the vertebral artery, near the origin of the posterior inferior cerebellar artery. Post-traumatic vertebral artery pseudoaneurysm is rare, but associated with a high mortality rate. We report on an extremely rare case of post-traumatic pseudoaneurysm of the vertebral artery with delayed manifestation. A 9-year-old child was admitted to the emergency room after a pedestrian car accident. A computed tomography (CT) scan showed subarachnoid hemorrhage with intraventricular hemorrhage (IVH), multiple facial bones, and temporal bone fracture. External ventricular drainage and decompressive suboccipital craniectomy were performed for acute hydrocephalus and posterior fossa swelling. The patient's clinical condition became suddenly aggravated on the 15th hospital day, and brain CT confirmed appearance of a new 4th ventricle IVH. Digital subtraction angiography revealed a ruptured pseudoaneurysm arising from the right V4 segment of the vertebral artery. Parent artery occlusion using detachable coils was achieved. Despite intensive care, the patient's clinical condition showed continuous deterioration and the patient died of respiratory complications on the 52nd hospital day. PMID:27169084

    A 68-year-old woman presenting with gastrointestinal bleeding (hematocrit 19.3%) and in a critical clinical condition (American Society of Anesthesiologists grade 4) from a giant superior mesenteric artery pseudoaneurysm (196.0 x 131.4 mm) underwent emergency endovascular treatment. The arterial tear supplying the pseudoaneurysm was excluded using a 5.0 mm diameter and 31 mm long monorail expanded polytetrafluoroethylene (ePTFE)-covered self-expanding nitinol stent. Within 6 days of the procedure, a gradual increase in hemoglobin levels and a prompt improvement in the clinical condition were observed. Multislice CT angiograms performed immediately, 5 days, 30 days and 3 months after the procedure confirmed the complete exclusion of the pseudoaneurysm.

    Pseudoaneurysms of the subclavian artery remain a rare complication after fracture of the clavicle. We report a case of delayed diagnosis of a subclavian artery pseudoaneurysm after a closed fracture of the clavicle in a 15-year-old patient, 3 months after the original injury while playing rugby union. Despite several attendances to the Emergency Department with vague symptoms, the final diagnosis was confirmed by duplex ultrasound and Computed Tomography of the thorax. Surgical repair was indicated due to acute limb ischaemia from distal embolisation from a large pseudoaneurysm, with the patient making a full recovery. This case highlights the need for clinical vigilance when assessing patients, particularly on repeated occasions when their recovery appears to be impaired. A thorough history and clinical examination can raise suspicion of even rare occurrences and aid prompt management. PMID:26351589

    This study reports 6 cases of hemoptysis originating from infectious pulmonary artery pseudoaneurysms (PAPs). Selective pulmonary angiography revealed PAPs in 5 cases, and segmental pulmonary artery embolization was performed using coils and gelatin sponge particles. Systemic arterial embolization also was performed in 5 cases because of inadequate initial control or for shunts from systemic to pulmonary arteries. At a median follow-up time of 9 months (range, 25 d to 25 mo), no recurrence occurred, although 2 patients died of respiratory failure. Segmental artery embolization combined with systemic artery embolization may be useful in patients with hemoptysis secondary to PAPs. PMID:26095272

    Iatrogenic intracranial pseudoaneurysm formation and rupture are rare complications following endoscopic sinus surgery. Given the propensity for devastating neurologic injury after a relatively routine procedure, swift diagnosis and treatment is essential. The authors present a patient who experienced bifrontal intracranial hemorrhage and subarachnoid hemorrhage due to a ruptured iatrogenic frontopolar artery pseudoaneurysm caused during routine endoscopic sinus surgery. The pseudoaneurysm was not present on initial angiograms but became apparent radiographically 19 days after the endoscopic procedure. Endovascular treatment consisted of coil and Onyx embolization for sacrifice of the parent vessel proximal to the lesion. Early recognition of iatrogenic intracranial vascular injury is important to allow for rapid treatment. Initial radiographic studies may be unreliable in excluding the presence of a pseudoaneurysm so delayed repeat angiographic assessment is necessary, particularly in the presence of a high index of clinical suspicion. Endovascular techniques may provide an effective and safe option for the treatment of iatrogenic anterior cerebral artery distribution pseudoaneurysms. PMID:25994943

    This report describes an unusual case of lumbosacral plexopathy resulting from internal iliac artery pseudoaneurysm. A 50-yr-old woman presented with multiple penetrating trauma to the thorax, abdomen, and left buttock. Several weeks after the injury, severe sciatica and motor dysfunction developed in her left leg. Progressively worsening pain was followed by left foot drop. An electrodiagnostic evaluation suggested a lower lumbosacral plexopathy. Magnetic resonance imaging showed a hematoma extending adjacent to the left lumbosacral plexus. Computerized tomographic angiography revealed a left internal iliac artery pseudoaneurysm. The pseudoaneurysm was excised surgically. In the early postoperative period, the patient reported total relief of pain. Her motor function recovered gradually over several weeks; however, some residual weakness of foot dorsiflexion persisted. With this case presentation, we underscore that an arterial pseudoaneurysm should be remembered as an etiologic possibility of lumbosacral plexopathy and sciatica, especially in patients with history of iatrogenic or accidental trauma. An increased awareness of this rare cause of sciatica and lumbosacral plexopathy may enable early intervention alternatives. PMID:18388559

    Although aneurysmal complications of sickle cell anemia have been described in the intracranial circulation, visceral artery pseudoaneurysms in this disease entity have not previously been reported in the literature. Conventional treatment of visceral pseudoaneurysms has been surgical ligation or resection of the aneurysm. Transcatheter embolization has emerged as an attractive, minimally invasive alternative to surgery in the treatment of these lesions. In certain situations, however, due to the unfavorable angiographic anatomy precluding safe transcatheter embolization, direct percutaneous glue injection of the pseudoaneurysm sac may be considered to achieve successful occlusion of the sac. The procedure may be rendered safer by simultaneous balloon protection of the parent artery. We describe this novel treatment modality in a case of inferior pancreaticoduodenal artery pseudoaneurysm in a patient with sickle cell anemia. Although a complication in the form of glue reflux into the parent vessel occurred that necessitated surgery, this treatment modality may be used in very selected cases (where conventional endovascular embolization techniques are not applicable) after careful selection of the balloon diameter and appropriate concentration of the glue-lipiodol mixture.

    We would like to report our experience of a rather rare complication that occurred in a 76-year old patient tree years after endovascular repair of a splenic artery pseudoaneurysm with a covered stent. Three years after stent insertion, the patient complained of mild abdominal pain and melena; it was revealed endoscopically that the covered stent has eroded the stomach wall and migrated into the stomach. The splenic artery is the most common location among the spectrum of potential presentation sites of visceral arteries aneurysms and pseudoaneurysms. Endovascular treatment with the use of coils or stents is the first option due to lower morbidity and mortality than open surgery. Endovascular repair may also lead to complications and patients need to be followed up in order to confirm aneurysm sealing, and exclude late complication. Minor stent graft migration may occur in the long term, however extra vascular migration is extremely rare. PMID:27200159

    Arthroscopy of the foot and ankle is a common orthopedic procedure with low complication rates. Arterial injuries from these procedures are an even more rare subset of the complications. Hemophilia A is a genetic disorder of aberrant coagulation, which leads to increased risk of bleeding even after minor trauma. We present the second case of anterior tibial artery pseudoaneurysm formation secondary to ankle arthroscopy in a hemophiliac patient and suggest that these individuals are at higher risk for developing complications associated with arterial injury. Furthermore, potential risk factors include port placement, anatomic variation of the vessels, and nature of the arthroscopic procedure. We recommend steps to prevent complications in hemophiliac patients. PMID:27174350

    Background: Superficial temporal artery (STA) pseudoaneurysms have been reported in the literature since the mid of seventeenth century from Bartholin, however, there is an increasing number of cases, suggesting a diversity of etiological factors. Among these, traumatic events, even of an iatrogenic nature, have been identified as causative factors for nonspontaneous STA pseudoaneurysms. Regional pain and tenderness, troublesome pulsations of the mass, cosmetic concerns as well as the risk of bleeding warrant a thorough evaluation and a definite interventional approach to the condition. Case Description: A 21-year-old Caucasian male searched medical advice for a growing, tender, and pulsatile mass on his right temple, with isolated and short episodes of lancinating sensations, after sustaining a blunt trauma following a hit with a stick half a year before the admission. Enhanced cranial computed tomography and angiography confirmed the diagnosis of an STA pseudoaneurysm. A direct percutaneous aspiration, as well as ultrasonography, was performed prior to the neurosurgical intervention, with the complete removal of the mass. Conclusions: STA pseudoaneurysms require a careful evaluation and a conclusive approach in order to avoid the risk of a growing mass and other nonremote complications such as bone erosions and bleeding. Different treatment options are available, including endovascular obliteration and embolization, however, surgical removal after ligation of the afferent and efferent segments of the vessel seem to be highly effective.

    Splenic artery aneurysms (SAA) are the third most common intra-abdominal aneurysm. Complications include invasion into surrounding structures often in association with preexisting pancreatic disease. We describe an 88-year-old female, with no history of pancreatic disease, referred with lower gastrointestinal bleeding. CT angiography showed a splenic artery pseudoaneurysm with associated collection and fistula to the transverse colon at the level of the splenic flexure. The pseudoaneurysm was embolised endovascularly with metallic microcoils. Rectal bleeding ceased. The patient recovered well and follow-up angiography revealed no persistence of the splenic artery pseudoaneurysm. SAA rupture results in 29%-50% mortality. Experienced centres report success with the endovascular approach in haemodynamically unstable patients, as a bridge to surgery, and even on a background of pancreatic disease. This case highlights the importance of prompt CT angiography, if endoscopy fails to identify a cause of gastrointestinal bleeding. Endovascular embolisation provides a safe and effective alternative to surgery, where anatomical considerations and local expertise permit. PMID:27559488

    Arterial pseudoaneurysm of the lower limb is an infrequent entity, particularly in the infrapopliteal segment. It is commonly associated to vascular repairs or follows a localized arterial lesion, a fracture or a surgical procedure. There is little information in Mexico about this entity in cases involving the anterior tibial artery, and secondary to trauma and osteosynthesis. Given that sudden bleeding due to rupture of the pseudoaneurysm is a possible catastrophic outcome for the viability of the segment, it is important to timely detect and diagnose the pseudoaneurysm. Treatment indications contained in the international literature are controversial. Solution-oriented approaches may be either surgical or endovascular. Current reports show that the best treatment option is an autologous saphenous vein graft, which maintains blood flow and minimizes the risk of peripheral ischemia. The purpose of this paper is to report the case of a patient who sustained the above mentioned complication and provide a literature review. This topic should be further investigated, as this condition may go unnoticed in a large number of cases, given that its symptoms are silent. PMID:27627775

Experienced centres report success with the endovascular approach in haemodynamically unstable patients, as a bridge to surgery, and even on a background of pancreatic disease. This case highlights the importance of prompt CT angiography, if endoscopy fails to identify a cause of gastrointestinal bleeding. Endovascular embolisation provides a safe and effective alternative to surgery, where anatomical considerations and local expertise permit. PMID:27559488

    Blunt traumatic injuries to the superior gluteal artery are rare in clinic. A majority of injuries present as aneurysms following penetrating trauma, fracture pelvis or posterior dislocation of the hip joint. We reported a rare case of superior gluteal artery pseudoaneurysm following blunt trauma presenting as large expanding right gluteal hematoma without any bony injury. The gluteal hematoma was suspected clinically, confirmed by ultrasound and the arterial injury was diagnosed by CT angiography that revealed a large right gluteal hematoma with a focal contrast leakage forming a pseudoaneurysm within the hematoma. Pseudoaneurysm arose from the superior gluteal branch of right internal iliac artery, which was successfully angioembolized. The patient was discharged on day 4 of hospitalization with resolving gluteal hematoma. This report highlighted the importance of considering an arterial injury following blunt trauma to the buttocks with subsequent painful swelling. Acknowledgment of this rare injury pattern was necessary to facilitate rapid diagnosis and appropriate treatment. PMID:27578385

    To characterize extrahepatic pseudoaneurysm regarding incidence and etiology and determine the effectiveness of endovascular management. A retrospective audit of 1,857 liver transplants in two institutions was performed (1996-2009). Recipients' demographics, clinical presentation, transplant type, biliary anastomosis, and presence of biliary endoprostheses were noted. Pseudoaneurysms were classified into iatrogenic (associated with biliary endoprosthesis or angioplasty) or spontaneous extrahepatic pseudoaneurysms. Spontaneous and iatrogenic pseudoaneurysms were compared for time from transplant, presenting symptoms, location in the arterial anatomy, and 3-month graft survival. Arterial patency and 6-month graft survival were calculated. Twenty pseudoaneurysms were found (1.1 %, 20/1,857): 9 (0.5 % of transplants, 9/1,857) were spontaneous and 11 (0.6 % of transplants, 11/1,857) were 'iatrogenic' (due to minimally invasive procedures: 4 angioplasty and 7 biliary endoprostheses). Sixty percent (12/20) underwent endovascular management (4 coil embolization and 8 stent-grafts). Technical success was 83 % (10/12) with a mean arterial patency of 70 % (follow-up mean, 4.9; range, 0-18 months). The 1-, 3-, and 6-month graft survival was 70, 40, and 35 %, respectively. Due to minimally invasive procedures, posttransplant extrahepatic pseudoaneurysms are no longer an exclusive complication of the transplant surgery itself. Endovascular management is effective to stabilize patients but has not improved historic postsurgical graft survival.

    We report a very unusual complication of uretero-iliac artery fistula that developed following robotic radical cystectomy (RARC), bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch reconstruction. Our patient was a 54-year-old male who was admitted 1 month after undergoing robotic surgery due to intermittently occurring massive transurethral bleeding necessitating blood transfusion that stopped by itself. Angiography showed a right external iliac artery pseudo-aneurysm and a fistula tract between the pseudo-aneurysm and Wallace type ureteral anostomosis that was successfully treated by an angiographic endovascular stent insertion at this level. Uretero-iliac artery fistula might occur following RARC, bilateral extended pelvic lymph node dissection and intracorporeal Studer pouch reconstruction leading to intermittently massive transurethral bleeding. Angiography and stenting are important for diagnosis and successful treatment of this rare entity. PMID:24069106

    Less invasive surgery and interventional radiology are relatively new techniques. This case report describes a patient with a distal tibial fracture that was stabilized using minimally invasive osteosynthesis consisting of a precontoured metaphyseal Locking Compression Plate (LCP). Postoperative radiographs showed good alignment of the bone, and the initial postoperative course was uneventful. At the sixth-week follow-up visit after surgery, the patient presented with a pulsating and tender mass on the lower leg that was palpable subcutaneously. Arteriography showed a pseudoaneurysm of the anterior tibial artery. At the same procedure an endovascular stent was placed, thereby excluding the pseudoaneurysm from the main circulation while keeping the vessel lumen patent. At the time of the last visit, 6 months after the operation, the patient was fully weightbearing with normal function of the ankle but with a nonhealing fracture on the x-ray. The dorsalis pedis pulse was equally strong as on the right side. Endovascular treatment with a covered stent proved to be an effective treatment for the described posttraumatic pseudoaneurysm of the anterior tibial artery. This case illustrates a risk of less invasive fracture surgery and at the same time underlines the value of a multidisciplinary approach to complications in trauma surgery. PMID:17414557

    Pulmonary mucormycosis is a rare opportunistic invasive fungal infection involving the pulmonary vasculature in immunocompromised patients. Pseudoaneurysm of pulmonary artery in mucormycosis is a rare fatal complication after invasion and rupture of a pulmonary artery. We report a patient with diabetes mellitus and incidental lung cancer who developed massive hemoptysis because of a huge pseudoaneurysm of the left pulmonary artery by mucormycosis. Although the patient had been managed by amphotericin B followed by left pneumonectomy for persistent hemoptysis, he died from septic shock and multiorgan failure after surgery. Histologic analysis of a surgical specimen revealed concomitant squamous cell lung cancer. PMID:25441799

    An aberrant internal carotid artery (ICA) is a rare abnormality associated with life-threatening otorrhagia if inadvertently injured during middle-ear surgery including myringotomy. We present a case where a 3-year-old girl experienced massive otorrhagia following myringotomy, and computed tomographic scan showed the aberrant ICA. Bleeding was controlled by ear canal packing, but rebleeding occurred. Investigations by carotid angiography demonstrated a pseudoaneurysm of the aberrant ICA in the middle ear. We attempted surgical repair using a high-flow bypass technique; however, the bypass graft was occluded by embolic complications, and eventually, ligation of the ICA was performed, which led to the paralysis of the patient's left limbs. In this report, management of iatrogenic aberrant ICA injuries and pseudoaneurysms in the middle ear are discussed based on the case that we experienced. PMID:27085819

    Classically, hepatic artery pseudoaneurysms (HAPs) arise secondary to trauma or iatrogenic causes. With an increasing prevalence of laparoscopic procedures of the hepatobiliary system the risk of inadvertent injury to arterial vessels is increased. Pseudoaneurysm formation post injury can lead to serious consequences of rupture and subsequent hemorrhage, therefore intervention in all identified visceral pseudoaneurysms has been advocated. A variety of interventional methods have been proposed, with surgical management becoming the last step intervention when minimally invasive therapies have failed. The authors present a case of a HAP in a 56-year-old female presenting with jaundice and pruritis suggestive of a Klatskin’s tumor. This presentation of HAP in a patient without any significant past medical or surgical intervention is atypical when considering that the majority of HAP cases present secondary to iatrogenic causes or trauma. Multiple minimally invasive approaches were employed in an attempt to alleviate the symptomology which included jaundice and associated inflammatory changes. Ultimately, a right hepatic trisegmentectomy was required to adequately relieve the mass effect on biliary outflow obstruction and definitively address the HAP. The presentation of a HAP masquerading as a malignancy with jaundice and pruritis, rather than the classic symptoms of abdominal pain, anemia, and melena, is unique. This presentation is only further complicated by the absent history of either trauma or instrumentation. It is important to be aware of HAPs as a potential cause of jaundice in addition to the more commonly thought of etiologies. Furthermore, given the morbidity and mortality associated with pseudoaneurysm rupture, intervention in identifiable cases, either by minimally invasive or surgical interventions, is recommended.

    Spontaneous cervical extradural pseudoaneurysms or arteriovenous fistulas (AVFs) are rare vascular diseases. We report a case of ruptured occipital artery (OA) pseudoaneurysm associated with occipital-internal jugular vein (IJV) fistula in neurofibromatosis type 1. Endovascular internal trapping via the OA was attempted; however, the distal entry of the OA could not be accessed because of the high shunt flow and tortuosity of the OA. The distal part of the OA was obliterated with coil via a transvenous approach through the IJV and pseudoaneurysm. The proximal entry of the OA was obliterated with coil and glue under proximal flow control with a balloon, and the fistula was successfully obliterated without placement of coils in the pseudoaneurysm. When ordinary internal trapping via a transarterial approach is not possible, the transvenous approach should be considered as an alternative for AVF associated with an aneurysmal component.

    Pancreatitis is a known cause of pseudoaneurysms of the peripancreatic arteries, which can rarely rupture into various adjacent structures and become a source of life-threatening bleeding. The management is challenging and requires an individualised approach and multidisciplinary care. Herein, we present the case of a 24-year-old man in whom a splenic pseudoaneurysm ruptured into the adjacent infected pseudocyst, communicating with the colon by a fistulous tract, causing massive lower gastrointestinal bleeding. This was successfully managed by transcatheter arterial embolisation (TAE). PMID:23208811

    Pseudoaneurysm of the internal mammary artery (IMA) following median sternotomy is extremely rare. To date, the reported cases are only in single figures. The majority of these pseudoaneurysms were suspected from the clinical presentation, echocardiography or computed tomography (CT) but were only confirmed on contrast angiography. This case report demonstrates the current ability to carry out detailed vascular imaging on a 16-slice CT scanner. This accurate delineation of the pseudoaneurysm allowed targeted therapeutic embolization to be performed without unnecessary angiographic imaging.

    Before the advent of ultrasound, percutaneous pericardiocentesis was associated with relatively high mortality and complication rates (6% and 20–50%, respectively) [1–3]. Ultrasound (US)-guided pericardiocentesis has dramatically decreased the incidence of complications by direct visualization of the heart and other adjacent vital structures. US helps localize the size and location of the pericardial effusion, measure the distance from the chest wall, localize adjacent, vital organs, and determine the optimal access site to the effusion. We report a case of posttraumatic internal mammary artery pseudoaneurysm, a rare complication of pericardiocentesis. PMID:27141247

    Pseudoaneurysms of the lower limb are rare and frequently iatrogenics complications. Closed traumas are likely to generate lesions of the arterial wall, which generally become symptomatic at a later stage. The diagnosis of such vascular lesion is difficult because the symptomatology and the onset can be delayed. We herein report the case of a 15-year-old patient in whom the diagnosis of pseudoaneurysm of the anterior tibial artery was made 5 months after a non-displaced closed fracture of the tibial shaft. The radiographs were evocative of a malignant bone tumor. The study of vessels by a contrast-enhanced CT-scan enabled us to diagnose the pseudoaneurysm. Before the occurrence of late onset swelling, a history of trauma must be sought, even old. PMID:27447879

    Background: Spontaneous superficial temporal artery (STA) pseudoaneurysms are very rare; only four cases, including ours, have been reported to date. Therefore, the cause of them has not been studied. Case Description: A 57-year-old woman was admitted to our hospital with a pulsatile mass in the left preauricular region. Her medical history included hypertension, dyslipidemia, and angina pectoris. She denied a history of head injury or minor head trauma. Three-dimensional computed tomography angiography showed a well-enhanced saccular aneurysm on the main trunk of the STA. To prevent rupture it was removed surgically. The histological diagnosis was pseudoaneurysm with atherosclerosis. By the 2nd postoperative day, she had completely recovered and was discharged home. There has been no relapse. Conclusions: As all four documented patients were at high risk for atherosclerosis, we posit that a causal factor was weakening of the arterial wall due to atherosclerosis and chronic pressure on the STA from anatomical structures. Here, we present histological evidence to support this hypothesis. PMID:27127716

    A cystic artery aneurysm is a rare cause of hemobilia. Herein, we report two cases of acute cholecystitis with a ruptured cystic artery pseudoaneurysm. Two patients (a 69-year-old man and an 83-year-old man) were admitted to our hospital because of acute cholecystitis with gallstone impaction in the neck. Percutaneous transhepatic gallbladder drainage (PTGBD) was performed for both patients. After a few days of PTGBD, gallbladder hemorrhage was observed. Abdominal angiography showed cystic artery aneurysm. A transcatheter arterial embolization was therefore performed, followed by an open cholecystectomy. PMID:27593367

    Mediastinal pancreatic pseudocyst (MPP) is a rare, but known, complication of both acute and chronic pancreatitis. Most pseudocysts are associated with alcoholic pancreatitis. Recent advances in endoscopic techniques have shown promising results, with reduced chances of infection and recurrence than with percutaneous drainage, but limited availability restricts widespread use. Left gastric artery pseudoaneurysm with mediastinal pseudocyst has not been described in the literature to date. We report a successful resolution of hemorrhagic MPP with embolization of pseudoaneurysm and percutaneous trans-hepatic pseudocyst drainage. PMID:25502760

    A 35-year-old man presented to our emergency room with asymptomatic jaundice. A physical exam revealed a palpable mass with audible bruit in the epigastrium. Total serum bilirubin was 21.7 mg%. A real time sonography/Doppler examination showed widening of the biliary tree (common bile duct diameter of 13 mm) and a mass in the pancreatic head with turbulent flow. Arteriography of the celiac axis revealed a pseudoaneurysm of the gastroduodenal artery. A ligation of the gastroduodenal artery was performed surgically, and the aneurysmal cavity was explored and emptied. An intraoperative cholangiography showed slight stenosis of the common bile duct distally, and so a choledochojejunostomy was performed. The patient's recovery was uneventful. A follow-up angiogram revealed the short stump of the gastroduodenal artery and no aneurysm or extravasation of dye. A follow-up ultrasound showed the common bile duct measuring 5.5 mm. The bilirubin level dropped to normal values. The patient was discharged on 12 days after surgery. Ten months following surgery he was doing well. The pathology, diagnosis, and treatment of such cases are briefly discussed. PMID:11433208

She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm. This was treated with an endovascular stent resulting in slightly improved motor function, but the significant residual deficit required subsequent rehabilitation to improve right upper limb function.

    The rupture of a mycotic femoral artery pseudoaneurysm in an intravenous drug abuser is a limb- and life-threatening condition that necessitates emergency intervention. Emergency stent-grafting appears to be a viable, minimally invasive alternative, or a bridge, to subsequent open surgery. Caution is required in cases of suspected concomitant deep vein thrombosis in order to minimize the possibility of massive pulmonary embolism during stent-grafting, perhaps by omitting stent-graft postdilation or by inserting an inferior vena cava filter first. We describe the emergency endovascular management, in a 60-year-old male intravenous drug abuser, of a ruptured mycotic femoral artery pseudoaneurysm, which was complicated by a fatal pulmonary embolism.

    We present a case of a 52-year old female patient with intermittent gastrointestinal bleeding and iron deficiency anaemia. Repeated endoscopic investigation revealed no diagnosis, but contrast-enhanced computed tomography showed a splenic artery pseudo-aneurysm secondary to chronic alcoholic pancreatitis. A distal pancreatectomy and splenectomy was performed. Hemosuccus pancreaticus is an uncommon cause of gastrointestinal bleeding, most frequently associated with chronic pancreatitis. Erosion of a peripancreatic artery by a pseudocyst can cause a pseudoaneurysm and rupture occurs in up to 10% of the cases. Bleeding from a pseudocyst wall or rupture of an atherosclerotic or traumatic aneurysm is rare. Angiography, contrast-enhanced computed tomography and endoscopic findings can be diagnostic in the majority of cases. Angiographic embolization or surgery are both therapeutic options depending on underlying nonvascular pancreas related indications requiring surgery. We discuss diagnostic pitfalls and current therapeutic strategies in the management of this disease. PMID:26712055

    Internal carotid artery (ICA) lesions in the parapharyngeal space (a dissection and a pseudoaneurysm) may present as isolated lower cranial nerves (IX, X, XI, and XII) palsy (Collet-Sicard syndrome). Some arteriopathies such as fibromuscular dysplasia and tortuosity make a vessel predisposed to dissection. Extreme vessel tortuosity makes the treatment by a stent graft impossible. Two Silk stents were used in a 46 year-old man with left lower cranial nerves (IX-XII) palsy for the treatment of left ICA spontaneous dissection with pseudoaneurysm. A follow-up angiogram 5 months later confirmed pseudoaneurysm thrombosis and patency of the left ICA. The patient recovered completely from the deficits.

    An 82-year-old woman developed acute occlusion of her right coronary artery. She underwent percutaneous coronary stent placement and aortic balloon pump installation. In the postprocedural period, she developed a common femoral artery pseudoaneurysm (PSA) that communicated with the common femoral vein via an arteriovenous fistula (AVF). After unsuccessful ultrasound-guided compression, ultrasound-guided thrombin injection of the PSA was performed, with simultaneous balloon occlusion of the common femoral vein at the level of the AVF. There was complete thrombosis of the PSA and AVF.

    Pseudoaneurysm of aorta is a rare condition usually seen after aortic surgeries or serious accidents. Here we report a 60 years old man without any previous medical condition who presented with non-specific symptoms and underwent different investigations for more than 1 year, until the presence of a continuous murmur raised suspicion toward his cardiovascular system. In echocardiographic and computed tomography (CT) angiographic studies a large pseudoaneurysm of aortic arch with compression effect on pulmonary artery was detected. At this stage he remembered having suffered a minor trauma 10 years ago. He finally underwent operation and his aortic wall was repaired successfully with a patch. This case highlights the importance of thorough history taking and physical examination in patients irrespective of symptoms and high index of suspicion to detect this life-threatening condition.

    Vacuum-assisted closure (VAC) therapy in the management of sternal wound infection post cardiac surgery has gained popularity since last decade. It is very cost effective and has survival benefit compared with conventional management. Although there are few complications associated with VAC therapy including right ventricular free wall rupture and infectious erosion to aorta, there are now isolated reports of vein graft pseudoaneurysm associated with it. We describe an extremely rare complication of right internal mammary artery pseudoaneurysm post VAC therapy in a 56-year-old man which was successfully managed surgically. We also did a literature review on the possible complications of VAC therapy post cardiac surgery and its management. PMID:26597235

    Introduction Symptomatic hepatic-artery pseudoaneurysm (HAP) after bile-duct injury (BDI) is a rare complication with a varied (but clinically urgent) presentation. Methods A prospectively maintained database of all patients with BDI at laparoscopic cholecystectomy (LC) referred to a tertiary specialist hepatobiliary centre between 1992 and 2011 was searched systematically to identify patients with a symptomatic HAP. Care and outcome of these patients was studied. Results Eight (6 men) of 236 patients with BDI (3.4%) with a median age of 65 (range: 54?6) years presented with symptomatic HAP. Median time of presentation of the HAP from the index LC was 31 (range: 13?16) days. Bleeding was the dominant presentation in 7 patients. One patient presented late (>2 years) with abdominal pain alone. Computed tomography angiography was the most useful investigation. Angioembolisation was successful in 7 patients. One patient died, and another patient developed liver infarction. Three patients (38%) developed biliary strictures after embolisation. Seven patients are alive and well at a median follow-up of 66 months. Conclusions Presentation of HAP is often delayed. A high index of suspicion is necessary for the diagnosis. Computed tomography angiography is the first-line investigation and selective angioembolisation can yield successful outcomes. PMID:27580308

    The treatment of posttraumatic aneurysms of peripheral arteries using covered stents is increasingly commonplace. We present the case of a 10-year-old girl with a pseudoaneurysm of the subclavian artery complicated by an arteriobronchial fistula with hemorrhaging into the bronchial tree and distal subclavian artery occlusion. Despite the lack of artery patency, endovascular stent graft implantation was successful. Pseudoaneurysm exclusion and involution was achieved, together with a patent implant and maintained collateral circulation patency.

    Although n-butyl-2-cyanoacrylate (NBCA) has been used as an effective liquid embolization material, its indication for pseudoaneurysms has seemingly been limited because of the technical difficulties of using NBCA, such as reflux to the parent artery and causing significant infarction. Thus, considerable skill in using NBCA or a device to control blood flow during its polymerization is required to achieve embolization without severe complications. We report our new technique for controlling blood flow using diluted epinephrine in transcatheter arterial NBCA embolization of five pseudoaneurysms in four cases secondary to hemosuccus pancreaticus.

    Total knee replacements (TKRs) are performed to treat debilitating arthritis and are one of the most routinely performed surgical procedures in the United Kingdom. Complications of infection and deep vein thrombosis are well recognized and managed, whereas neurovascular injuries are rarely reported although should not be disregarded. We report on the case of a 72-year-old man who presented 5 weeks after a TKR with symptoms of a progressively worsening ipsilateral foot drop. A diagnosis of common peroneal nerve neuropathy secondary to the compressive effects of a popliteal pseudoaneurysm was made, and he underwent uneventful patch repair of the pseudoaneurysm. Unique to the literature is the chronicity of the foot drop, which still persisted at follow-up 6 weeks later. PMID:26140945

    Acute or chronic blood loss from pseudoaneurysms of the splanchnic artery in chronic pancreatitis poses diagnostic and management challenges. Arteriographic examination offers both diagnostic and therapeutic options, with success rates of 76%-100% for both modalities. In cases of failure of embolization, repeat embolization is also an option. Surgical intervention is advocated for rebleeding and failure of embolization. Evidence-based guidelines regarding the optimal treatment modality for this condition are lacking. There has been a reported case of dislodgement of coil into the stomach through a gastropseudocystic fistula. We report the case of a migrating steel-wire coil through the gastrointestinal tract and splenic artery pseudoaneurysm. We highlight the potential complications of pseudoaneurysm and other available therapeutic management options.

  6. Life-threatening rupture of an external iliac artery pseudoaneurysm caused by necrotizing fasciitis following laparoscopic radical cystectomy: a case report

    2014-01-01

    Background Pseudoaneurysms are caused by trauma, tumors, infections, vasculitis, atherosclerosis and iatrogenic complications. In this paper, we report about a patient with rupture of an external iliac artery pseudoaneurysm, which lead to hemorrhagic shock, after undergoing laparoscopic radical cystectomy and extended pelvic lymphadenectomy. Case presentation The patient was a 68-year-old Japanese male diagnosed with invasive bladder cancer. Laparoscopic radical cystectomy and extended pelvic lymphadenectomy were performed. On postoperative day 12, he developed a high fever and an acute inflammatory response with redness and swelling in the right inguinal region. He was diagnosed with necrotizing fasciitis and underwent debridement. On postoperative day 42, a sudden hemorrhage developed from the open wound in the right inguinal region. He was diagnosed with external iliac artery pseudoaneurysm rupture by computed tomography. Conclusion These complications occur extremely rarely after cystectomy with pelvic lymphadenectomy. There are no reports to date on these complications following laparoscopic cystectomy with pelvic lymphadenectomy. PMID:24885366

    The diagnostic value of common ultrasound and contrast-enhanced ultrasonography (CEUS) in hepatic artery pseudoaneurysm (HAP) after liver transplantation was investigated. From January 2005 to November 2015, information was collected on 2,085 cases of orthotopic liver transplantation. The cases included 1,617 men and 468 women. Common ultrasound and CEUS were used to monitor arterial blood flow following surgery, and the complications were assessed. Instruments used included Acuson Sequoia 512 and Mylab Twice, and the contrast agent was SonoVue. The standard of common ultrasound in the diagnosis of HAP was follicular structure, which had arterial blood flow signal present beside the hepatic artery. The diagnostic criteria of HAP using CEUS were abnormal and round contrast enhancement zone and perfusion of the contrast agent in the zone near the hepatic artery. The diagnostic standard of HAP was computed tomographic angiography (CTA) and emergency operation. Eight cases of HAP were diagnosed in 2,085 patients after liver transplantation (0.38%). Three cases of HAP were diagnosed successfully by common ultrasound while 5 cases were missed. Sensitivity, specificity and diagnostic accuracy for common ultrasound was 37.5, 100 and 99.76%, respectively. Six cases of HAP were diagnosed by CEUS and 2 cases were missed. Sensitivity, specificity and diagnostic accuracy for CEUS was 75, 100 and 99.9%, respectively. Collectively, CEUS is a convenient and effective diagnostic method for HAP following liver transplantation, the diagnostic sensitivity was obviously higher than that of the common ultrasound, and it was more convenient than CTA. Nevertheless, the diagnosis of pseudoaneurysm with deep location, and unsatisfactory grayscale images were easily missed. PMID:27446316

    We present the case of a late superficial femoral artery stent disconnection causing an asymptomatic pseudoaneurysm successfully treated with a stent-graft. A 67-year-old female was referred to our department for evaluation of claudication of the left lower limb and was diagnosed to have a total occlusion of the superficial femoral artery. Three nitinol stents were used to revascularize this artery. At 48 months, duplex-ultrasonography control revealed the presence of a 45-mm saccular femoral dilatation; X-rays and CT angiography showed fractures of the proximal stents and the presence of a pseudoaneurysm at the site of the distal stents disconnection. The pseudoaneurysm was excluded using two stent-grafts. We conclude that patients and surgeons should be aware of structural complications with all stents. Rigorous follow-up controls should be mandatory. Endovascular repair proved to be feasible and durable to manage a previous endovascular procedure.

    Post–partum haemorrhage is a major determinant of maternal mortality. Traditionally, cases of post–partum haemorrhage caused by arterial injuries were managed by caesarean hysterectomies or bilateral internal iliac artery ligations. The diagnosis of aneurysms or arteriovenous malformations of uterine artery are often missed. Uterine curettage, caesarean section or vaginal delivery can result in uterine vascular anomalies like pseudo aneurysms, arteriovenous malformations, arteriovenous fistula and rupture of uterine vessels. Colour Doppler ultrasound pelvis allows detection of these vascular abnormalities. It helps in differentiating the vascular abnormalities that require embolization from non–vascular abnormalities which can be managed by uterine curretage. Vessel malformations can be treated safely with transcatheter uterine artery embolization, but they can develop disastrous consequences with inadvertent uterine curettage. Transcatheter uterine artery embolization after pelvic angiography is the treatment of choice for uterine artery malformations and it has the advantage of preserving the reproductive capacity. We recommend a routine use of colour Doppler ultrasound pelvis for evaluation of abnormal uterine bleeding. PMID:24298511

    Visceral aneurysms are potentially life-threatening vascular lesions. Superior mesenteric artery (SMA) pseudoaneurysms are a rare but well-recognized complication of chronic pancreatitis. Open surgical repair of such an aneurysm, especially in patients after previous surgical treatment, might be dangerous and risky. Stent graft implantation makes SMA pseudoaneurysm exclusion possible and therefore avoids a major abdominal operation. Percutaneous direct thrombin injection is also one of the methods of treating aneurysms in this area. We report a first case of percutaneous ultrasound-guided thrombin injection to complete SMA pseudoaneurysm exclusion after an unsuccessful endograft placement. Six-month follow-up did not demonstrate any signs of aneurysm recurrence.

    Thrombin injection has been proven to be successful in postcatheterization pseudoaneurysms. However, there are only a few reports on the treatment of pseudoaneurysms of the trunk. We report our first experiences using a percutaneous as well as an endovascular access. Eight iatrogenic pseudoaneurysms of the trunk (aorta, n = 4; pulmonary artery, n = 1; gastroduodenal artery, n = 1; left gastric artery, n = 1, renal artery, n = 1) were treated either percutaneously using CT guidance (n = 3) or via an endovascular access (n = 5). Noninvasive control angiograms were performed at day 1 and weeks 1 and 3 by either CT or MR angiography. The total volume of the pseudoaneurysms was 31.2 {+-} 23.1 ml on average, with a mean volume of the perfused aneurysmal lumen of 12.9 {+-} 7.2 ml. The maximum diameter was 4.1 {+-} 1.39 cm on average. In each case, the aneurysmal neck was not wider than 2 mm. One pseudoaneurysm occluded spontaneously following selective catheterization. The remaining pseudoaneurysms were successfully treated by injection of 765 {+-} 438.1 IU thrombin. In one individual, a nontarget embolization occurred, as well as an intervention-associated rupture of a pseudoaneurysm. High-grade stenoses of the donor artery were found in a different case. Only once was the endoluminal access converted to a percutaneous one. Thrombin injection might be a future first-line treatment of vascular lesions such as pseudoaneurysms of the trunk. In our experience both percutanous and endoluminal access are technically feasible and safe. However, further experiences are mandatory, especially concerning the question of dosage and long-term results.

    Partial nephrectomy can be associated with vascular complications. Computed tomography (CT) with CT angiography is ideal for noninvasive imaging of this process. The treatment of choice is selective embolization.

    Objective: Penetrating carotid trauma in a hemodynamically stable patient invariably presents with a pseudoaneurysm on initial imaging. Although extremely rare, delayed pseudoaneurysm formation has been reported. The purpose of this paper is to define this rare entity and propose a diagnostic and treatment plan. Methods: We present a case of delayed presentation of carotid pseudoaneurysm following penetrating neck trauma. A systematic review of the literature was performed. Results: A 21-year-old male presents to the trauma center after sustaining a gunshot wound to the left upper back resulting in a zone 2 hematoma and pneumothorax. Bullet fragment artifact interfered with computed tomography. Carotid angiogram was normal. The patient was discharged after 3 days. He returned to the Emergency Department 3 months later with a painful pulsatile hematoma. Computed tomography angiogram revealed a 6-cm pseudoaneurysm arising from the proximal left internal carotid artery (ICA). A left common carotid artery (CCA) to ICA bypass with reversed great saphenous vein was performed. The patient’s post-operative course was uneventful, neurologic deficits improved, and he was discharged. Conclusion: Delayed presentation of traumatic pseudoaneurysms has been reported, although usually these cases are iatrogenic access complications in extremities. While endovascular therapies are first line for zone 1 and 3 vascular injuries, management of zone 2 injuries is still controversial. This patient was treated with a bypass due to the need to evacuate the hematoma that was exerting a mass effect in the neck. PMID:27489718

    Vascular injury as a consequence of dislocated bone fragments after hip fractures is a rare complication. We report a case of a 78-year-old male who developed a pseudoaneurysm of the profunda femoris artery during rehabilitation after intramedullary fixation for a pertrochanteric hip fracture. As this procedure was minimally invasive, open reposition and fixation of the dislocated lesser trochanter were not performed. The pseudoaneurysm was diagnosed through duplex ultrasound and CT angiography and treated with thrombin injections and an endovascular Wallgraft covered stent. The imaging features are described in the article. Although a pseudoaneurysm is a rare complication after hip fractures, the development should be considered, in particular when symptoms such as pulsatile swelling or venous engorgement are presented.

    An intrahepatic artery pseudoaneurysm (IHAA) is a very rare but potentially lethal complication occurring after liver transplantation. This report presents a case of an IHAA associated with a metallic biliary stent after liver transplantation. A 40-year-old male underwent living donor liver transplantation (LDLT) using a left lobe graft. The bile duct reconstruction was performed with Roux-en-Y hepaticojejunostomy. He developed obstructive jaundice 5 years after LDLT, and had biliary stricture of the anastomosis area, therefore, the two metallic biliary stents were finally positioned at the stricture of the biliary tract. He suddenly developed hematemesis 8 years after LDLT, and computerized tomography scan showed an IHAA. Although seven interlocking detachable coils were placed at the neck of the aneurysm, hematemesis recurred 3 days after the initial embolization. Therefore, retransplantation was successfully performed 25 days after the embolization of IHAA using a right lobe graft from his son. In conclusion, metal stent insertion can lead to the fatal complication of HAA. The placement of a metallic stent could have been avoided in this case. Percutaneous metallic stent insertion for biliary stenosis after liver transplantation should therefore only be performed in carefully selected patients. PMID:22914885

    Abstract Background: Pseudoaneurysm of the aortic arch is uncommonly associated with cancer, and is extremely rare in pulmonary cancer. Here, we report an unusual and successfully treated case of aortic arch pseudoaneurysm in a male patient with lung squamous cell carcinoma. Methods: A 64-year-old male patient was admitted to the Emergency Department, presenting with massive hemoptysis (>500 mL blood during the 12 hours prior to treatment). The diagnosis of aortic arch pseudoaneurysm was confirmed after inspection of computed tomographic angiography and three-dimensional reconstruction. We processed the immediate endovascular stent-grafting for this patient. Results: This patient recovered with no filling or enlargement of the pseudoaneurysm, no episodes of hemoptysis, and no neurological complications during the 4-week follow-up period. Conclusion: Herein, we compare our case with other cancer-related pseudoaneurysms in the medical literature and summarize the clinical features and treatment of this unusual case. PMID:27495079

    Patient: Male, 77 Final Diagnosis: Femoral artery pseudoaneurysm Symptoms: None Medication: — Clinical Procedure: Cardiac catheterization and coronary stenting with Starclose vascular closure Specialty: Interventional Cardiology Objective: Educational Purpose (only if useful for a systematic review or synthesis) Background: Vascular closure devices (VCDs) are frequently used for hemostasis with endovascular procedures by employing sutures or plug devices (using collagen or hydrogel) or through the use of a metal clip made of nickel and titanium, such as the StarClose SE device. In comparison to manual compression (MC), VCDs are associated with earlier time to discharge and ambulation, improved patient comfort, and better cost-effectiveness. Case Report: A 77-year-old man with history of ischemic cardiomyopathy with non-ST segment elevation myocardial infarction (NSTEMI) underwent diagnostic cardiac catheterization with deployment of a StarClose SE vascular closure device for hemostasis. Upon repeat access 4 days later for coronary intervention, retrograde sheath angiography revealed a pseudo-aneurysm emanating from the center of the StarClose clip. Conclusions: A review of the literature shows VCDs to be non-inferior to MC, with an overall high success rate. Major and minor complications rates are comparable to those with MC, and pseudo-aneurysm is an infrequent complication. PMID:27026227

    A 25-year-old man developed sudden pain and a pulsating mass in the left thigh. A diagnosis of Behcet's disease was made because of four major symptoms. Laboratory data indicated active inflammation. Emergency spiral computed tomographic angiography (CTA) showed an aneurysm of the left superficial femoral artery (SFA). Under steroid therapy, follow-up spiral CTA showed spontaneous occlusion of the aneurysm. In the active phase of arteritis, spiral CTA is useful for the diagnosis of arterial lesions to avoid the arterial puncture of conventional arteriography.

    A pseudoaneurysm refers to a contained rupture of the myocardium with a tenuous pericardium walling off the leak. It needs to be differentiated from a true aneurysm by the fact that there is lack of myocardial tissue in the wall of a pseudoaneurysm. The differentiation between the two is pertinent as true aneurysms can be treated medically while pseudoaneurysms require urgent surgical treatment. Untreated pseudoaneurysms carry a high risk of rupture and mortality. We report a case of cardiac pseudoaneurysm developing in a 46-year-old male who had suffered myocardial infarction four months back. The patient now presented with chest pain and dyspnoea. CECT chest revealed a partially thrombosed large pseudoaneurysm arising from the posterior wall of left ventricle. While the clinical diagnosis of this entity is difficult, CECT plays a pivotal role in the non-invasive detection of pseudoaneurysms. PMID:27504379

    The study was aimed at analysing strategies of prevention of puncture-related complications in patients with myocardial infarction undergoing subjected to emergency coronary interventions by means of a femoral arterial access. We carried out a retrospective comparative analysis of two strategies aimed at preventing false aneurysms of femoral arteries: Group One (232 cases) - elective use of special devices for closure of puncture defects in patients with high risk of haemorrhage (previously performed thrombolytic therapy; exogenous obesity of the second-third degree, 2-3 degree arterial hypertension, use of 2b/3a blood platelet receptors inhibitors); Group Two (525) cases - conventional routine use of these technologies. Puncture defects were closed using by means of devices Cordis Exoseal and St.Jude Angio-Seal. The obtained results suggested advantage of the conventional approach: demonstrating a statistically significant (p < 0.05) decrease in the total incidence of false aneurysms of femoral arteries (from 5.2 to 1.9%) and the frequency of cases requiring surgical suturing of the defect in the femoral artery (from 1.7 to 0.2%). In the conditions of an intensive flow of emergency patients presenting with acute coronary pathology and requiring coronary interventions, devices for closing defects in the femoral arterial access make it possible to level puncture complications. Over the examined period of 2013-2014 there were performed more than 600 closures of defects of the femoral artery by means of the Cordis ExoSeal. These devices proved to be efficient, reliable, and very simple to use. A decrease in the incidence rate of puncture-related complications was also associated with rational prescription administration of drugs influencing positively various links of haemostasis.

    Aortic arch pseudoaneurysm is a rare condition but carries a high risk of rupture. We report a case of a 45-year-old man with aortic arch pseudoaneurysm between left common carotid artery (LCCA) and left subclavian artery (LSA), in which a endovascular stent graft combined with double chimneys covered stents were successfully placed. There were no any complaints and complications after 12 months follow-up. The CTA demonstrated thrombus formation in the pseudoaneurysm lumen, no endoleak and the aortic arch, LCCA and LSA were all patent. We feel that the combined endovascular and double chimneys may be a valuable therapeutic alternative when treating aortic arch lesion. However, long-term clinical efficacy and safety have yet to be confirmed. PMID:23577875

    A pseudo aneurysm results from leakage of blood from an artery after trauma or dehiscence or separation of a surgical anastomosis. The reported rate of pseudo aneurysm in access sites range from 0.88% to 8%. It has some cause like penetrating trauma, blunt trauma and endovascular procedure. The differential diagnoses of this lesion are hematoma, AV fistula, lymphadenopathy, lymphocele, DVT, compartment syndrome, soft tissue tumor. A 16 years old male was referred to our clinic with progressive swelling in his right leg for the past three month. In primary survey (MRI, CT, Bone Scan) patient was diagnosed with soft tissue tumor, but after biopsy and angiography he was diagnosed with pseudo aneurysm of anterior tibialis artery. Despite easy diagnosis of p aneurysm in most cases, the signs and symptoms are more likely to soft tissue mass in rare cases. So pseudo aneurysm should always be considered as one differential diagnosis for soft tissue tumors. PMID:24901729

    Purpose: To assess the effectiveness of tissue adhesive and thrombin solution in the percutaneous ablation of peripheral artery pseudoaneurysms.Methods: Twenty-five pseudoaneurysms were treated over a 33-month period; all had failed ultrasound-guided compression. Tissue adhesive or thrombin solution was injected percutaneously, with needle tip position and changes within the aneurysm confirmed with color Doppler ultrasound. In 19 cases we utilized a protective balloon inflated across the aneurysm neck prior to the injection of tissue adhesive and in six cases used thrombin injection alone. Seven patients were anticoagulated. Patients were followed up after the procedure.Results: All 25 aneurysms were treated successfully; two patients required a return visit and there were no immediate complications or peripheral emboli detected. One patient developed a contralateral pseudoaneurysm.Conclusions: The percutaneous injection of pseudoaneurysms is a safe, a traumatic, and effective treatment for femoral artery pseudoaneurysms in the peripheral circulation. There are significant advantages over ultrasound-guided compression or surgical repair.

    We describe a rare case of carotid pseudoaneurysm secondary to a retropharyngeal abscess, treated with coil embolization in a 2-year-old boy. The patient presented to an emergency department with symptoms suggesting meningitis but was subsequently diagnosed with streptococcal pharyngitis. He was discharged home on oral antibiotics after a short hospitalization. He returned to the emergency department two weeks later with limited neck motion and pain. Neck CT demonstrated a retropharyngeal abscess with a large left cervical internal carotid artery (ICA) pseudoaneurysm. The petrous ICA distal to the pseudoaneurysm had thrombosed prior to treatment. The ICA proximal to the pseudoaneurysm was sacrificed with coil embolization. Post-treatment imaging demonstrated complete thrombosis of the pseudoaneurysm but also demonstrated acute strokes in the left MCA/ACA watershed distribution. His parents noted that the patient was clumsier and exhibited some mild speech changes and a steppage gait prior to evaluation in the ED; therefore, these were thought to be secondary to emboli from partial thrombosis of the pseudoaneurysm prior to treatment. The patient was discharged home in good condition and his neurological function improved. PMID:26060279

    Pseudoaneurysms of abdominal aorta after inferior vena cava (IVC) filter placement are uncommon, with associated morbidity and mortality. We report a case in which an abdominal aortic pseudoaneurysm resulted from erosion of a Bird's Nest (Cook, Bloomington, IN) IVC filter into the wall of the abdominal aorta. A 64-year-old woman with an IVC filter placed 10 years prior presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen and pelvis showed a 1.4-cm x 2.0-cm infrarenal aortic pseudoaneurysm adjacent to the IVC filter site. A Zenith endograft (Cook) was used via an open femoral artery exposure to successfully treat the pseudoaneurysm. PMID:16765254

    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

    A 48-year-old man who had undergone implantation of two paclitaxel-eluting stents (PESs) at the right coronary artery was admitted to our hospital with progressive dyspnea. In the coronary care unit, he developed cardiogenic shock due to cardiac tamponade treated by pericardiocentesis. A coronary angiogram showed a large pseudoaneurysm at the site of the previously implanted stents, suggesting coronary rupture due to implanted stent fracture. The pseudoaneurysm was completely sealed by polytetrafluoroethylene-covered stent implantation. Although this case is very rare, coronary rupture by stent fracture should be considered when cardiac tamponade occurs after drug-eluting stent implantation, especially PES. PMID:25998891

    We report a case of a 74-year-old woman with a 16-year history of a double bilo-enteric anastomosis due to resected hilar cholangiocarcinoma (Type IIIb Klatskin tumor). The patient presented with cholangitis secondary to benign anastomotic stenosis which resulted in a large intrahepatic biloma. In order to restore the patency of the anastomosis and overcome cholangitis, several attempts took place, including endobiliary stenting, balloon-assisted biloplasty and transhepatic billiary drainage. Anastomotic patency was achieved, complicated, however, by persistent upper gastro-intestinal bleeding, presented as hemobilia. A biloma-induced pseudoaneurysm of the left hepatic artery was diagnosed. This had ruptured into the biliary tract, and presented the actual cause of the hemobilia. Selective embolism of the pseudoaneurysm resulted in control of the hemorrhage, and was successfully combined with transhepatic dilatation of the anastomosis and percutaneous drainage of the biloma. The patient was ultimately cured and seems to be in excellent condition, 5 mo after treatment. PMID:16127759

    Swelling around the knees can be due to both neoplastic as well as non neoplastic aetiology. One of the rare cause for the same is pseudoaneurysm. Pseudoaneurysms can mimic a bone tumor or a soft tissue sarcoma. Pseudoanuerysms result because of the gradual growth occurring due to constant arterial pressure and development of a reactive fibrous capsule. Inappropriate diagnosis and management of these lesions may result in major morbidity and rarely mortality. We present two cases of pseudoaneurysms around the knees which were misdiagnosed as osteogenic sarcomas. These cases also stress on the importance of multidisciplinary care, in preventing avoidable morbidity, mortality and providing safe and optimal care to the patients. PMID:27437336

    This report presents the case of a 30-year-old motocross (BMX) cyclist with a third-degree posterior cruciate ligament rupture. The technique used for reconstruction was the transtibial single-bundle autologous hamstring technique. Unfortunately, the procedure was complicated by a popliteal pseudoaneurysm, which was located in line with the tibial canal. The pseudoaneurysm was treated with an end-to-end anastomosis and the patient recovered without further complaints. In this case, the popliteal artery was damaged most probably by the edge of the reamer or the guide wire during removal. Vascular complications can be limb- and life-threatening. This case report aims to increase the awareness of this serious complication with a review of the literature. PMID:25229050

    A 16-year-old male patient with hereditary multiple exostoses (HME) was found to have a pseudoaneurysm of the left popliteal artery caused by osteochondroma in the lower femur. The diagnosis was confirmed by ultrasound, magnetic resonance imaging and magnetic resonance angiography without the need to perform an angiogram. The osteochondroma was excised and the popliteal artery was repaired with a saphenous graft. Vascular complications are extremely rare in HME, pseudoaneurysm being the most common and mostly located in the popliteal artery. This complication should be considered in young HME patients with a mass at the knee region. The radiological spectrum of investigations allows the diagnosis of this complication with proper and less invasive management procedures for the patient.

    Summary The study assessed the effectiveness and safety of endovascular covered stents in the management of intracranial pseudoaneurysms, fusiform aneurysms and direct carotid-cavernous fistulas. Fourteen endovascular covered stents were used to repair three pseudoaneurysms, six fu-siform aneurysms and six direct carotid-cavernous fistulas. Aneurysms were in the carotid artery in seven cases, in the vertebral artery two cases. It was not possible to treat two additional cases transcutaneously for technical reasons
2/15. Percutaneous closure of the lesions with an endovascular covered stent was successful in 13 of 15 cases. Initial follow-up showed good stent patency. No complications were observed after stent implantation. During follow-up, stent thromboses were detected in two of nine patients with follow-up digital subtracted angiography. One carotid-cavernous fistula of Barrow Type A transformed into Barrow Type D at nine month follow-up study was cured with a procudure of Onyx-18 injection. Endovascular covered stents may be an option for percutaneous closure of intracranial pseudoaneurysms, fusiform aneurysms and direct carotid-cavernous fistulas. Endoluminal vascular repair with covered stents offers an alternative therapeutic approach to conventional modalities. PMID:20557743

    Internal carotid artery pseudoaneurysm is a rare life-threatening condition that may develop in different clinical situations. We report the case of an extracranial internal carotid artery pseudoaneurysm secondary to a throat infection in a pediatric patient that was initially treated with percutaneous thrombin injection under ultrasound guidance. However, recanalization occurred at 48 h, and definitive treatment was then performed by endovascular stent-graft placement. We briefly review the clinical characteristics of this uncommon clinical condition as well as the treatment options.

    Abstract Hematuria resulting from urethral traumatic catheter insertion and removal is often encountered. Usually, hematuria resolves with conservative measures. We report a case of traumatic Foley removal leading to intermittent life-threatening hematuria resulting in blood loss anemia requiring multiple transfusions and multiple episodes of hypotension requiring pressors. A pelvic angiogram revealed a pseudoaneurysm of the left pudendal artery, which was treated with microcoil embolization leading to resolution of bleeding.

    Purpose. To describe our preliminary experience with a new liquid embolization agent, Onyx, in peripheral interventions. Methods and results. We successfully treated two peripheral aneurysms (one in an internal iliac artery, one in a thoracic collateral artery of an aortic coarctation), two peripheral pseudoaneurysms (one in a lumbar artery, one in a renal artery), and one pulmonary arteriovenous malformation. Conclusion. Onyx is a promising alternative embolic material for peripheral interventions. It can be combined with coils in selected cases, and balloon catheters can be effectively used during slow injection of embolic material to control flow and protect the aneurysm neck.

    A mycotic pseudoaneurysm of the popliteal artery is usually a consequence of septic embolization and often a result of bacterial endocarditis. Conventional treatment is surgical and avoids the placement of foreign material in infected sites. Here we report our treatment of a 59-year-old man who presented with a rupture of a mycotic pseudoaneurysm of the popliteal artery due to septic embolism from sternoclavicular infectious arthritis. Radiological investigations are included. This is the first documented case of septic arthritis complicated by a rupture of a mycotic popliteal false aneurysm and treated using an endovascular procedure. Combining endovascular stent grafts with evacuation of the joint abscess and antibiotic therapy can offer a safe alternative for frail and unstable patients. PMID:22664287

    We report two patients who developed a tracheo-innominate artery fistula (TIF) after tracheostomy. Contrast-enhanced computed tomography revealed a pseudoaneurysm of the innominate artery protruding into the trachea. Stent grafts were deployed for the innominate artery via two different access routes: the transfemoral approach and the right carotid artery approach. Endovascular stent-graft repair resulted in complete exclusion of the TIF and control of the bleeding from the tracheal stoma. At 12- and 16-month follow-ups, neither patient had clinical signs of graft infection, recurrent fistulization, or ischemic complications. It is feasible and useful to employ the carotid artery approach for stent-graft implantation in patients who have vascular anatomical limitations for the transfemoral approach. Endovascular repair of TIF by stent grafting is a minimally invasive treatment that can be tolerated by patients in poor clinical condition, and is a feasible alternative to surgical treatment.

    A 74-year-old man presented with a ruptured infected anastomotic femoral pseudoaneurysm. Due to severe medical comorbidities he was considered unsuitable for conventional surgical management and underwent an emergency endovascular repair with a balloon-expandable covered stent. The pseudoaneurysm was excluded successfully and the patient had an uneventful postoperative recovery with long-term suppressive antimicrobials. He remained well for 10 months after the procedure with no signs of recurrent local or systemic infection and finally died from an acute myocardial infarction. To our knowledge, emergency endovascular treatment of a free ruptured bleeding femoral artery pseudoaneurysm has not been documented before in the English literature. This case illustrates that endovascular therapy may be a safe and efficient alternative in the emergent management of ruptured infected anastomotic femoral artery pseudoaneurysms when traditional open surgery is contraindicated.

    The interventional angiographic techniques using the percutaneous femoral approach for endovascular revascularization are becoming increasingly more popular. These methods usually require larger sheaths, and most patients need postprocedural anticoagulation or antiplatelet therapy. As a consequence, the interventional procedure is associated with a higher rate of complications at the arterial entry site compared to diagnostic angiography. The reported incidence of iatrogenic pseudoaneurysm formation after coronary artery interventions ranges from 3.2% to 7.7%, and the rates noted after diagnostic angiography range from 0.2% to 1%. Peripheral pseudoaneurysms have traditionally been treated by surgical intervention, but nonsurgical alternatives, such as ultrasound (US)-guided compression, coil embolization, stent-graft placement, and percutaneous thrombin injection with or without balloon occlusion have also been documented. Of these alternatives, direct percutaneous embolization with embolic agents is the most popular method. The tissue adhesive n-butyl cyanoacrylate (NBCA) (Hystoacryl) (B. Braun, Melsungen, Germany) is one of the most popular occluding agents for neurovascular interventions, and has been widely used for more than 20 years [5,6]. In this study, we evaluated the efficacy and utility of direct percutaneous injection of NBCA for embolization of femoral pseudoaneurysms.

    Purpose: To evaluate the therapeutic role of angiography in patients with pseudoaneurysms complicating pancreatitis. Methods: Thirteen symptomatic pseudoaneurysms were treated in nine patients with pancreatitis. Eight patients had chronic pancreatitis and pseudocyst and one had acute pancreatitis. Clinical presentation included gastrointestinal bleeding in seven patients and epigastric pain without bleeding in two. All patients underwent transcatheter embolization. Results: Transcatheter embolization resulted in symptomatic resolution in all patients. Rebleeding occurred in two patients, 18 and 28 days after embolization respectively, and was successfully treated by repeated emnbolization. One patient with severe pancreatitis died from sepsis 28 days after embolization. Follow-up was then available for eight patients with no relapse of bleeding after a mean follow-up of 32 months (range 9-48 months). Conclusion: Transcatheter embolization is safe and effective in the management of pseudoaneurysms complicating pancreatitis.

    Ventricular free wall rupture remains the most serious complication after acute myocardial infarction. In early-recognized, subacute cases a surgical intervention using patches can be lifesaving. However, in the rare case of postoperative patch leakage, a relapse of a pseudoaneurysm may occur. This is the first case in the literature-to the best of our knowledge-describing a minimally invasive strategy using CT fluoroscopic guidance to perform an injection of thrombin into the perfused pseudoaneurysm to seal a leakage. This therapeutical regimen was chosen-in accordance with cardiac surgeons, cardiologists, and interventional radiologists-due to the high risk of adverse event after repeated surgery in this particular patient. The follow-up images showed complete occlusion of the pseudoaneurysm after the thrombin injection. This approach could be discussed in a multidisciplinary setting in similar cases, especially due to the described negligible recurrence rate after successful initial thrombosis after treating femoral pseudoaneurysms, pseudoaneurysms of the pancreatic artery, or even endoleaks after stenting of aneurysms of the aorta.

    Introduction The use of angioembolisation in patients with lower gastrointestinal tract haemorrhage has become well established, especially in cases of diverticular bleeding, or in bleeding from arterio-venous malformations. Pseudoaneurysms are rare and the evaluation of selective gelfoam angioembolisation amongst patients with lower gastrointestinal tract bleeding secondary to this etiology has not been extensively studied. The friable nature of pseudoaneurysms may lead to a greater risk of rupture during an attempted angioembolisation procedure. Presentation of case We describe the successful treatment and outcome of a lady who initially presented with perforation of the colon at the rectosigmoid junction, for which she underwent resection and anastomosis. A few days later, she was noted to have persistent hematochezia, which was secondary to bleeding pseudoaneurysms at the rectosigmoid branches of the inferior mesenteric artery. She successfully underwent selective angioembolisation of these pseudoaneurysms with gelfoam. She did not suffer any complications from the procedure. Discussion Although there have been significant advances in the armamentarium associated with percutaneous interventional radiology procedures for hemostasis in gastrointestinal bleeding, the use of selective angioembolisation for bleeding pseudoaneurysms have not been readily adopted due to the friable nature of the wall of the pseudoaneurysm, and its risk for rupture. Our case report illustrates that angioembolisation in such cases is feasible, and should be a consideration especially when the risk of surgical intervention is high. Conclusion Selective gelfoam angioembolisation should be considered in the management of patients with bleeding from the gastrointestinal tract secondary to pseudoaneurysms. PMID:27111875

Over a 3-year period, six patients with a mean age of 68.7 years (range 58-75) were identified who had proximal anastomotic aortic pseudoaneurysms secondary to previously implanted bifurcated aortic grafts (mean 15, range 12-20 years) following open surgical correction of aortoiliac occlusive disease. Five patients (83%) presented with concomitant palpable femoral anastomotic pseudoaneurysms and one patient (16%) had a pulsatile abdominal mass. All patients had computed tomographic (CT) scans confirming proximal anastomotic pseudoaneuryms without evidence of infection. The mean diameter of the pseudoaneurysms was 5.3 cm (range 4.0-7.0). Five patients were treated with endovascular methods, while one patient was not suitable for endovascular repair due to the diameter of the native aorta as seen on imaging study at the time of the procedure. AneuRx aortic extender cuffs (3.75 cm length) were deployed sequentially in five patients via a femoral approach. Devices were overlapped approximately 1.5 cm in order to achieve total exclusion of the pseudoaneurysms, and all concomitant femoral aneurysms were repaired surgically at the same time. Successful exclusion of the anastomotic pseudoaneurysm was achieved in four patients (80%) using a combination of two or three overlapping aortic cuffs. One patient had a small residual endoleak that had sealed by 1 month, evidenced by follow-up CT. The renal arteries were preserved in all patients. The average estimated blood loss and operative time were 355 +/- 25 cc and 84 +/- 21 min, respectively. The average length of hospital stay was 2.1 days, and there was no mortality or major morbidity. All patients underwent CT scanning

    Background: Intracranial giant vertebral artery aneurysms are extremely rare in the pediatric population and are associated with significant morbidity and mortality. The present report describes a case of a pediatric patient with giant vertebral artery aneurysm who presented with intracranial mass effect. This patient was successfully treated with endovascular parent artery occlusion and coil embolization. Case Description: A 7-year-old girl presented with tetraparesis, ataxia, dysphagia, and dysphonia. Cerebral angiography revealed intracranial giant aneurysm arising from the right vertebral artery. The patient underwent endovascular parent artery occlusion alone to facilitate aneurysmal thrombosis as an initial treatment. This was done to avoid a coil mass effect to the brainstem. However, incomplete thrombosis occurred in the vicinity of the vertebral artery union. Therefore, additional coil embolization for residual aneurysm was performed. Two additional coil embolization procedures were performed in response to recurrence. Mass effect and clinical symptoms gradually improved, and the patient had no associated morbidity or recurrence at 2 years after the last fourth coil embolization. Conclusion: Intracranial giant vertebral artery aneurysms are rare and challenging in pediatric patients. Staged endovascular strategy can be a safe and effective treatment option. PMID:25071937

    Arthroscopic shoulder surgery is considered a safe and effective method of treating a variety of shoulder pathologies and is associated with a low complication rate. The type and rate of complications can vary, depending on the procedure, positioning, surgical time, and anesthesia. Fortunately, neurovascular injuries occur infrequently. Numerous studies have described the proximity of neurovascular structures to portals placed in shoulder arthroscopy, in both the beach chair and the lateral decubitus positions. Accurate portal placement is important to avoid damage to adjacent neurovascular structures. Inaccurate placement of portals can lead to inadvertent damage to these structures and create more difficulty with visualization and angle of instrumentation, possibly compromising the success of the procedure. This article describes a 50-year-old man who underwent arthroscopic subacromial decompression and distal clavicle excision for persistent subacromial impingement and acromioclavicular arthritis. During postoperative follow-up, the patient had a small, bulging area located near the anterior portal site. Examination showed a well-healed anterior portal site with a small (approximately 2×2 cm), nontender, immobile mass located within the deep soft tissues just below the anterior portal incision. Ultrasound evaluation showed a pseudoaneurysm of a branch off the axillary artery. The patient underwent successful embolization of the pseudoaneurysm, with complete resolution of symptoms.

    The purpose of this paper is to report our experience with the endovascular treatment of crural arterial injuries using transcatheter and direct embolization techniques. A total of eight consecutive patients have been treated during a 7-year period. Six males and two females, mean age 32 years (range, 15-56 years), presented with penetrating trauma to the lower extremities. Mechanisms of injuries were stab wounds in six patients, gun shot wound in one patient, and iatrogenic injury in one patient. Five patients presented with acute trauma, while three patients presented with delayed injuries. Crural arterial injuries encountered included pseudoaneurysms with arteriovenous fistulas (n = 6), pseudoaneurysms with vessel transections (n = 2), and pseudoaneurysm (n = 1). Proximal and distal embolization with coils was used in three cases, proximal embolization with coils in three cases, percutaneous thrombin injection in one case, and liquid n-butyl cyanoacrylate in one case. Complete exclusion of the lesions was accomplished by sacrifice of one crural vessel in seven cases and of two crural vessels in one case. Two cases of delayed injuries required combined coil and liquid embolization techniques for lesion exclusion. A minor complication (groin hematoma) occurred in one patient, no distal ischemia was seen, and no amputations were required. Mean follow-up was 61 days (range, 1-180 days). One pseudoaneurysm treated with thrombin injection recurred and required surgical excision. We conclude that transcatheter embolization alone or in combination with different endovascular techniques is useful in the treatment of traumatic crural vessel injuries.

    PurposeExplore the application of endovascular covered stent-graft (SG) placement in femoral pseudoaneurysms in intravenous drug addicts.Materials and MethodsWe evaluated a consecutive series of pseudoaneurysm in intravenous drug addicts treated with SGs from August 2010 to December 2013.Results15 patients with 16 arterial pseudoaneurysms were enrolled in this study. All were males with a mean age of 36.9 years. Hemorrhage was the most common reason (93.8 %) for seeking medical care, and 3 of these patients were in hemorrhagic shock at admission. All patients received broad-spectrum antibiotics, and debridement and drainage were implemented after SG placement. 7 of the 13 cases which had microbiologic results showed mixed infections, while gram-negative bacteria were the major pathogens. Except for 2 patients, who were lost to follow-up, two new pseudoaneurysms formed due to delayed debridement, and one stent thrombosis occurred, none of the remaining cases had SG infection or developed claudication.ConclusionsSG placement controls massive hemorrhage rapidly, gives enough time for subsequent treatment for pseudoaneurysms due to intravenous drug abuse, and reduces the incidence of postoperative claudication. With appropriate broad-spectrum antibiotics and early debridement, the incidence of SG infection is relatively low. It is an effective alternative especially as temporary bridge measure for critical patients. However, the high cost, uncertain long-term prospects, high demand for medical adherence, and the risk of using the conduits for re-puncture call for a cautious selection of patients. More evidence is required for the application of this treatment.

    Pseudoaneurysm of the left ventricle most often occurs after transmural myocardial infarction but may also follow cardiac operations, trauma, inflammation, or infection. In contrast to patients with true ventricular aneurysm, those with false aneurysm most commonly die of hemorrhage. Review of the reported surgical experience and of our 14 cases confirms that standard chest radiographs with an abnormal cardiac silhouette and rapidly expanding size may alert the physician to this sometimes overlooked diagnosis. Noninvasive tests such as color-flow Doppler echocardiography, 2-dimensional echocardiography, cineangiographic computed tomography, and transesophageal echocardiography allow relatively easy recognition of these apparently rare lesions with increasing frequency. Cardiac catheterization, however, is usually still necessary for a clear picture of the location and anatomy of the aneurysm and the state of the coronary arteries. Finally, a new classification is proposed, consisting of true aneurysm, false aneurysm, pseudo-false aneurysm, and mixed aneurysm. Images PMID:7888805

A 64-year-old woman suffered hematoma and bleeding from a pseudoaneurysm probably originating from a branch of the right IMA 16 years after breast implant surgery. After clinical assessment, the patient underwent surgery with resection of the aneurysm and ligation of the arterial branch. No early postoperative complications were reported. Pseudoaneurysms in small vessels such as the IMA or its branches are not well described in the literature. Proper diagnosis with imaging is of importance in order to determine treatment as each case is unique. Some cases can be managed conservatively. PMID:27470014

    Pseudoaneurysm of ascending aorta is an infrequent but well-recognized and potentially fatal complication after cardiac surgeries. The complication can develop early, delayed or late, and the presentation is also varied. We are presenting here two cases of pseudoaneurysm of ascending aorta following cardiac surgery that were successfully managed by the transcatheter method. The first one occurred following coronary artery bypass surgery and the second one occurred following double-valve replacement surgery. The aortic openings of these aneurysms were occluded with 12 mm and 10 mm atrial septal occluders, respectively, with a good outcome. An immediate postprocedure angiogram showed no residual flow into the sac. Six months of follow-up of both cases also showed excellent results. PMID:21976887

    Left ventricular pseudoaneurysm is a rare, but potentially fatal, condition that generally occurs as a complication of myocardial infarction, infective endocarditis, or cardiac surgery. Surgical repair is the treatment of first choice because of the marked risk of rupture, but deteriorated hemodynamics and complicated procedures to treat the pseudoaneurysm may lead to a high mortality rate. We report a 62-year-old woman with a large left ventricular pseudoaneurysm after mitral valve replacement for rheumatic mitral valve stenosis. Surgical repair was not performed due to the patient's refusal, but her pseudoaneurysm resolved spontaneously by 2 years after mitral valve replacement. Spontaneous obliteration of a large left ventricular pseudoaneurysm is very rare in a patient on warfarin therapy. This case suggests that a left ventricular pseudoaneurysm with a narrow neck may resolve spontaneously in rare settings. PMID:25224154

These are usually not true aneurysms; hence treatment of these cases poses a therapeutic challenge. In this case report, we describe a young Asian male who presented with a ruptured pseudoaneurysm of the distal branch of the anterior cerebral artery. It was treated successfully with endovascular embolization. To our knowledge, there are few reports of this entity in the literature. PMID:27048313

    Background. There are no Canadian prevalence studies on pulmonary arterial hypertension (PAH) to date. We described the characteristics of treated PAH patients and the healthcare utilization and costs associated with PAH in a population of public drug plan beneficiaries in Ontario, Canada. Methods. A retrospective cross-sectional analysis was conducted between April 2010 and March 2011 to identify treated PAH patients using population-based health administrative databases. We investigated demographic and clinical characteristics of treated PAH patients and conducted a cohort study to determine treatment patterns, healthcare utilization, and associated costs, over a one-year follow-up period (March 2012). Results. We identified 326 treated PAH cases in Ontario's publicly funded drug plan. Overall mean age was 59.4 years (±20.3 years) and over 77% of cases were women (n = 251). Combination therapy was used to treat 22.9% (n = 69) of cases, costing an average of $4,569 (SD $1,544) per month. Median monthly healthcare costs were $264 (IQR $96-$747) for those who survived and $2,021 (IQR $993-$6,399) for those who died over a one-year period, respectively (p < 0.01). Conclusions. PAH care in Ontario is complex and has high healthcare costs. This data may help guide towards improved patient management. PMID:27445555

    Penetrating gunshot wounds (GSWs) to the abdominal aorta are frequently lethal. Alternative management options for treatment of traumatic pseudoaneurysms of the abdominal aorta are illustrated by three patient case histories. Patient A sustained two GSWs to the abdomen (midepigastrium, right subcostal region). He was hypotensive in the field. Emergent laparotomy was undertaken with suture ligature of a celiac injury and distal pancreatectomy/splenectomy for a pancreatic injury. Postoperative abdominal CT for an intraabdominal infection with leukocytosis revealed a 4 cm traumatic pseudoaneurysm of the abdominal aorta that extended from the suprarenal aorta to the level of the renal arteries. Six weeks later, he underwent an open repair. Patient B sustained multiple GSWs to his right arm and right upper quadrant. He was hemodynamically stable. He underwent abdominal exploration for a grade 3 liver laceration. Postoperative abdominal CT revealed a supraceliac abdominal aortic pseudoaneurysm. An aortogram demonstrated a 1.5 cm defect in the aortic wall above the celiac trunk communicating with the inferior vena cava (IVC). He underwent endovascular repair with covered aortic stent graft. Patient C sustained multiple thoracoabdominal GSWs. He was hemodynamically stable. Emergent laparotomy revealed multiple left colonic perforations, two duodenal lacerations, and an unsalvageable left kidney laceration. Postoperatively, he developed a duodenal-cutaneous fistula with multiple intraabdominal abscesses. Serial CT scans revealed an enlarging infrarenal aortic pseudoaneurysm. He underwent angiographic coil embolization and intraarterial injection of thrombin into the pseudoaneurysm sac. The average time from injury to surgical treatment was 46 days (range 29-67). Postoperatively, none of the patients developed paraplegia. Advances in endovascular techniques have provided options to deal with traumatic pseudoaneurysms of the abdominal aorta.

    Intracranial pseudoaneurysms represent a potentially fatal complication of intracranial surgery. Our purpose is to describe their neuroradiological characteristics, prognostic features and possible treatment. Eight cases of postsurgical intracranial pseudoaneurysms have been observed at our institution since 1988. Four were observed following transsphenoidal (TS) surgery and four after pterional craniotomies. Two types of iatrogenic pseudoaneurysms were observed: "fusiform", probably due to weakening of the adventitia during surgical peeling of the tumour from the artery (three cases) and "saccular", occurring after a more focal or complete laceration of the vessel (five cases), more often after TS surgery. A thorough preoperative neuroradiological examination may identify anatomical conditions at risk for development of this severe complication. Postoperative neuroradiological follow-up is mandatory in cases in which unusual bleeding has occurred during the perioperative period, but absence of bleeding does not exclude the possible development of a pseudoaneurysm. Endovascular treatment of pseudoaneurysms represents a safe and durable procedure, specifically in those cases in which damage to the carotid siphon occurred during TS surgery. PMID:17122940

    We report a case of a 43-year-old man who developed intractable hematuria after percutaneous nephrolithotomy. Angiography detected a pseudoaneurysm arising from the lower polar artery; however, embolization could not be performed because of unfavorable vascular anatomy. A percutaneous thrombin injection under ultrasound guidance initially controlled the bleeding, but hematuria subsequently recurred as a result of recanalization of the aneurysm. The case was successfully managed with ultrasound- and fluoroscopic-guided direct injection of cyanoacrylate glue into the pseudoaneurysm.

    Purpose: The effectiveness of angiography and embolization in diagnosis and treatment were assessed in a cohort of patients presenting with upper gastrointestinal hemorrhage secondary to hepatic artery pseudoaneurysm following laparoscopic cholecystectomy. Methods: Over a 6-year period 1513 laparoscopic cholecystectomies were carried out in our region. Nine of these patients (0.6%) developed significant upper gastrointestinal bleeding, 5-43 days after surgery. All underwent emergency celiac and selective right hepatic artery angiography. All were treated by coil embolization of the right hepatic artery proximal and distal to the bleeding point. Results: Pseudoaneurysms of the hepatic artery adjacent to cholecystectomy clips were demonstrated in all nine patients at selective right hepatic angiography. In three patients celiac axis angiography alone failed to demonstrate the pseudoaneurysm. Embolization controlled hemorrhage in all patients with no further bleeding and no further intervention. One patient developed a candidal liver abscess in the post-procedure period. All patients are alive and well at follow-up. Conclusion: Selective right hepatic angiography is vital in the diagnosis of upper gastrointestinal hemorrhage following laparoscopic cholecystectomy. Embolization offers the advantage of minimally invasive treatment in unstable patients, does not disrupt recent biliary reconstruction, allows distal as well as proximal control of the hepatic artery, and is an effective treatment for this potentially life-threatening complication.

    A multinodular hepatocellular carcinoma (HCC) was treated with seven transarterial interventions via the hepatic artery over a 2-year, 5-month period before the eighth angiography showed a recurrent HCC in the anterior portion of the left hepatic lobe. The left internal mammary artery (IMA) was feeding the tumor. This was successfully treated with Lipiodol-transcatheter arterial embolization using a coaxial system via a branch of the left IMA. No complications resulted from the procedure. The left IMA should be considered as a possible feeding artery to an HCC occurring in the anterior portion of the left hepatic lobe.

    We present a case of spontaneous rupture of hepatocellular carcinoma (HCC) with poor liver function which was treated by transcatheter arterial embolization (TAE). The patient's bilirubin value was 3.8 mg/dL. The tumor was fed by the right renal capsular artery according to selective arteriography. It was subsequently treated by TAE. With successful TAE, no hepatic failure was related to the treatment. We believe that if tumors are fed only by extrahepatic collateral vessels, TAE may be an effective treatment even in patients with poor liver function.

    This case illustrates successful treatment of a large postoperative intrasellar pseudoaneurysm with a polytetrafluoroethylene (PTFE)-covered stent. The advantages and potential disadvantages of this novel method of treatment are discussed. A previously healthy 59-year-old man underwent transsphenoidal operative treatment for hypophyseal macroadenoma,complicated by bleeding. On the 17{sup th} postoperative day the patient had profuse arterial bleeding from his nose requiring posterior tamponade. Subsequent angiography of the left internal carotid artery(ICA) revealed a large pseudoaneurysm located intrasellarly, with the orifice in the anteromedial wall in the ophthalmic segment of the ICA.Surgical treatment of the pseudoaneurysm was considered very risky. A12-mm PTFE-covered stent (JoMed, Ulestraten, Netherlands), manually compressed on a PTCA-balloon (Maxxum 4.5/13 mm, Boston Scientific,Ireland) was endovascularly delivered covering the orifice of the pseudoaneurysm. Control angiography immediately after the intervention and one year later revealed no flow into the pseudoaneurysm and the ICA was fully patent. In conclusion, deployment of a PTFE-covered stent proved to be feasible and successful in the treatment of an intrasellariatrogenic ICA pseudoaneurysm. Adequate anticoagulative treatment after the procedure is essential to prevent thrombotic complications.

    This paper describes four cases of visceral artery aneurysms (VAAs) successfully treated with endovascular stent-grafts and discusses the endovascular approach to VAAs and the long-term results. Four balloon expandable stent-grafts were used to treat three splenic artery aneurysms and one bleeding common hepatic artery pseudoaneurysm. The percutaneous access site and the materials were chosen on the basis of CT angiography findings. In all cases the aneurysms were successfully excluded. In one case a splenic infarction occurred, with nonrelevant clinical findings. At 16- to 24-month follow-up three patients had patent stents and complete exclusion and shrinkage of the aneurysms. One patient died due to pancreatitis and sepsis, 16 days after successful stenting and exclusion of a bleeding pseudoaneurysm. We conclude that endovascular treatment using covered stent-grafts is a valid therapeutic option for VAAs. Multislice CT preoperative study helps in planning stent-graft positioning.

    A 65-year-old male was diagnosed with purulent pericarditis, caused by Staphylococcus aureus five weeks after bare metal stenting for a 90% stenosis of the right coronary artery ostium. Subsequently, he developed a pseudoaneurysm in the right coronary sinus of Valsalva (CSV) requiring surgical intervention during the treatment of the pericarditis. Bacteremia after percutaneous coronary intervention (PCI) occurs in < 1% of patients and usually has insignificant clinical sequelae. We present an infected coronary bare metal stent of the proximal right coronary artery after PCI that resulted in a purulent pericardial effusion and mycotic pseudoaneurysm of the right coronary sinus of Valsalva (CSV). The patient successfully underwent surgical treatment. PMID:25783563

    Portal vein arterialization (PVA) has been applied as a salvage procedure in hepatopancreatobiliary surgeries, including transplantation and liver resection, with revascularization for malignancies. Here we describe the use PVA as a salvage procedure following accidental injury of the hepatic artery to the remnant liver occurred during left hepatic trisectionectomy for colorectal liver metastases (CRLM). A 60-year-old man with cancer of the sigmoid colon and initially unresectable CRLM received 11 cycles of hepatic arterial infusion chemotherapy with 5-fluorouracil (1500 mg/week), after which CRLM was downstaged to resectable. One month after laparoscopic sigmoidectomy, a left trisectionectomy and wedge resection of segment 6 were performed. The posterior branch of the right hepatic artery, the only feeding artery to the remnant liver, was injured and totally dissected. Because microsurgical reconstruction of the artery was impossible, PVA was used; PVA is the sole known procedure available when hepatic artery reconstruction is impossible. The patient then suffered portal hypertension, and closure of arterio-portal anastomosis using an interventional technique with angiography was eventually performed on postoperative day 73. Therefore, it is considered that because PVA is associated with severe postoperative portal hypertension, closure of the arterio-portal shunt should be performed as soon as possible on diagnosing portal hypertension.

    Background: To describe the application of an interposition graft bypass using superficial temporal artery (STA) for the treatment of a ruptured anterior cerebral artery (ACA) infectious aneurysm. Case Description: A 30-year-old male suffered from severe headache with high fever. The patient's diagnosis was ruptured infectious ACA aneurysm at the A3 segment with a maximum diameter of 4.5 mm, caused by infectious endocarditis. The patient was initially treated with high-dose intravenous antibiotics. Follow-up digital subtraction angiography (DSA) revealed that the fusiform aneurysm had enlarged to a maximum diameter of 14.0 mm. A left paracentral artery, supplying the motor area of the left lower extremity, originated from the body of this aneurysm. Because the angiographic findings suggested a risk of recurrent bleeding, the patient underwent open surgery. Interposition graft bypass using the STA was performed to reconstruct the left A3 segment in an end-to-side manner (left proximal callosomarginal artery – STA graft – left distal pericallosal artery). Then, the origin of the left paracentral artery was cut and anastomosed to the STA graft in an end-to-side manner. The affected parent artery was trapped, and the aneurysm was resected. Postoperative magnetic resonance imaging showed no ischemic or hemorrhagic complications, and postoperative DSA revealed the patency of the interposition graft. Pathological diagnosis of the resected aneurysm revealed features corresponding to infectious cerebral aneurysm. The postoperative course was uneventful, and the patient was discharged without any neurological deficits. Conclusion: In the treatment of infectious cerebral aneurysms, revascularization should be considered when the affected artery supplies the eloquent area. Interposition graft bypass using the STA is one of the options for revascularization surgery for the treatment of infectious ACA aneurysms. PMID:26862444

    Iatrogenic hepatic arterial injuries (IHAIs) include pseudoaneurysm, extravasation, arteriovenous fistula, arteriobiliary fistula, and dissection. IHAIs are usually demonstrated following percutaneous transhepatic biliary drainage, percutaneous liver biopsy, liver surgery, chemoembolization, radioembolization, and endoscopic retrograde cholangiopancreatography. The latency period between the intervention and diagnosis varies. The most common symptom is hemorrhage, and the most common lesion is pseudoaneurysm. Computed tomography angiography (CTA) is mostly performed prior to angiography, and IHAIs are demonstrated on CTA in most of the patients. Patients with IHAI are mostly treated by coils, but some patients may be treated by liquid embolic materials or stent-grafts. CTA can also be used in the follow-up period. Endovascular treatment is a safe and minimally invasive treatment option with high success rates. PMID:26359873

    Arterial wall disruption, as a consequence of inflammation/infection, trauma (penetrating or blunt), or iatrogenic causes, may result in pseudoaneurysm formation. Currently, iatrogenic causes are increasing as a result of the growth of endovascular intervention. The frequency of other causes also seems to be increasing, but this may simply be the result of increased diagnosis by better imaging techniques, such as multidetector contrast-enhanced computed tomography. Clinically, pseudoaneurysms may be silent, may present with local or systemic signs, or can rupture with catastrophic consequences. Open surgical repair, previously the mainstay of treatment, has largely been replaced by image-guided occlusion methods. On the basis of an experience of over 100 pseudoaneurysms, treatments at various anatomical sites, imaging modalities used for accurate diagnosis, current changing therapeutic options for pseudoaneurysm management, approved embolization agents, and clinical follow-up requirements to ensure adequate treatment will be discussed. Image-guided direct percutaneous and endovascular embolization of pseudoaneurysms are established treatment options with favorable success rates and minimal morbidity. The pendulum has now swung from invasive surgical repair of pseudoaneurysms to that of image-guided interventional radiology.

    A 56-year-old man presented with a 3-month history of progressive dizziness. His dizziness was aggravated when his head was rotated to the right side. Diagnostic angiography showed that a normal right-sided vertebral artery in the neutral position became an abnormal vertebral artery with two stenotic lesions at the C3–4 and C5–6 levels when the patient’s head was turned to the right. A normal left-sided vertebral artery also showed a stenotic lesion at the C2 level when the patient’s head was turned right. The axial dimensions of the bilateral vertebral arteries were similar. The patient was successfully treated with decompression of only one level (C5–6). We conclude that if a bilateral stenosis is found upon one directional head rotation and the bilateral vertebral arteries are similarly sized, a one-sided treatment may suffice. PMID:24390179

    Background. Pulmonary arterial hypertension (PAH) is a life-threatening disease characterized by an increase in pulmonary artery pressure leading to right ventricular (RV) hypertrophy, RV failure, and ultimately death. Current treatments can improve symptoms and reduce severity of the hemodynamic disorder but gradual deterioration in their condition often necessitates a lung transplant. Methods and Results. In experimental models of PAH, particularly the model of monocrotaline-induced pulmonary hypertension, efficacious treatment options tested so far include a spectrum of pharmacologic agents with actions such as anti-mitogenic, proendothelial function, proangiogenic, antiinflammatory and antioxidative. Emerging trends in PAH treatment are gene and cell therapy and their combination, like (progenitor) cells enriched with eNOS or VEGF gene. More animal data should be collected to investigate optimal cell type, in vitro cell transduction, route of administration, and number of cells to inject. Several recently discovered and experimentally tested interventions bear potential for therapeutic purposes in humans or have been shown already to be effective in PAH patients leading to improved life expectation and better quality of life. Conclusion. Since many patients remain symptomatic despite therapy, we should encourage research in animal models of PAH and implement promising treatments in homogeneous groups of PAH patients.

    Peroneal artery arteriovenous fistulas and pseudoaneurysms are extremely rare with the majority of reported cases due to penetrating, orthopedic, or iatrogenic trauma. Failure to diagnose this unusual vascular pathology may lead to massive hemorrhage or limb threatening ischemia. We report an interesting case of a 14-year-old male who presented with acute musculoskeletal pain of his lower extremity. Initial radiographs were negative. Further imaging workup revealed a peroneal arteriovenous fistula with a large pseudoaneurysm. After initial endovascular intervention was unsuccessful, the vessels were surgically ligated in the operating room. Pathology revealed papillary endothelial hyperplasia consistent with an aneurysm and later genetic testing was consistent with Ehlers-Danlos syndrome Type IV. This case illustrates an unusual cause of acute atraumatic musculoskeletal pain and uncommon presentation of Ehlers-Danlos syndrome. PMID:25349770

    Treatment of the femoropopliteal (FP) artery remains a challenge to the endovascular specialist. Long-term patency is low with a high rate of target lesion revascularization. The true patency rate varies considerably between studies partly because there is a lack of uniform performance criteria and reporting standards in peripheral arterial interventions. Literature review supports three principles that emerge as important components of an optimal strategy in treating the FP artery: (1) improving vessel compliance and subsequently less dissections and bailout stenting, (2) reducing smooth muscle cell proliferation, and (3) protecting outflow vessels from distal embolization. In this overview, we examine current data that support the validity of this strategy. PMID:24436577

    The objective of this study was to evaluate the efficacy and safety of intra-arterial thrombolysis in treating acute cerebral infarction and further discuss the indications of acute cerebral infarction treatment, in order to enhance the therapeutic effects of arterial thrombolysis. The data of 164 patients with acute cerebral infarction who accepted intra-arterial thrombolysis treatment by using rt-PA or reteplase between 2009 and 2014 at the Department of Neurology of our hospital, were collected, including patients' medical history, characteristics of the onset procedure, intervals between onset and intra-arterial thrombolysis, bleeding or death, and the changing process of patient's main neurologic function after the treatment. The neurological functions including muscle strength, speech, and level of consciousness were chosen for evaluation. Through a review of cerebral angiography, we collected the digital subtraction angiography (DSA) morphological changes of blood vessels before and after arterial thrombolysis to evaluate whether those blood vessels had been reperfused. Thereafter, we analyzed and statistically processed above-mentioned data. The mean time of arterial thrombolysis was 5.7 h. DSA results were as follows: 22 patients had complete internal carotid artery (ICA) occlusion; 49 patients middle cerebral artery's (MCA's) Ml or M2 segment occlusion; 6 patients anterior cerebral artery (ACA) occlusion; 58 patients reperfusion after thrombolysis, and the recanalization rate was 76 %. Based on vertebral-basilar artery (VBA) system, 18 patients had complete occlusion, 11 patients had reperfusion after thrombolysis, and the recanalization rate was 61 %. A total of 63 patients had severe stenosis, and they had significantly improved after thrombolysis. The clinical symptoms of patients were improved: 79 out of 164 patients with paralysis had partially recovered their limb muscle strength after operation, while 33 patients had completely recovered, and

    We report a rare case of a tuberculous mycotic aortoiliac pseudoaneurysm treated with an endovascular procedure and follow-up of 36 months. The patient was a white 72-year-old man with pulmonary tuberculosis and a former smoker with hypertension, chronic renal failure, and dyslipidemia. A computed tomographic scan of the abdomen and pelvis revealed a left paravertebral cavity with fluid content and involvement of vertebrae L2-L4. After a surgical repair attempt, the patient was treated with the implant of a bifurcated endoprosthesis. Because it is unlikely that any center has extensive experience in the management of this rare manifestation of the disease, we reviewed the literature for similar cases.

    Technically uncomplicated percutaneous angioplasty and stent placement of a left subclavian artery stenosis was performed in a 56-year-old man for treatment of subclavian steal syndrome and vertebrobasilar insufficiency. Six days later the patient was readmitted with Staphylococcus aureus bacteremia and stigmata of septic emboli isolated to the ipsilateral hand. Nine days later he had computed tomography (CT) evidence of a contrast-enhancing phlegmon surrounding the stent. Despite clinical improvement and resolution of bacteremia on intravenous antibiotic therapy, the phlegmon progressed, and at day 21 a pseudoaneurysm was angiographically confirmed. The patient underwent surgical removal of the stented arterial segment and successful autogenous arterial reconstruction. The possible contributory factors leading to stent infection were prolonged right femoral artery access and an infected left arm venous access. Although the role of prophylactic antibiotics remains to be defined, it may be important in cases where the vascular access sheath remains in place for a prolonged period of time.

    Until in the early nineties, pulmonary arterial hypertension (PAH) was a uniformly fatal disease, with a median life expectancy of approximately 2.5 years. Uncontrolled studies showed that a small proportion of patients responded to high-dose calcium channel blockers, retrospective studies supported the use of anticoagulant therapy and heart-lung or lung transplantation remained the only option. In 1996, a 3-month randomised, placebo-controlled trial showed that chronic intravenous epoprostenol (synthetic prostacyclin) improved functional state, exercise capacity, haemodynamics, and even survival in patients with idiopathic PAH. Similar benefits were subsequently reported and extended to all PAH categories, and confirmed with more stable prostacyclin analogues administered subcutaneously (treprostinil), by inhalation (iloprost), or even orally (beraprost). In the early 2000s, two randomised controlled trials showed efficacy of the oral intake of the dual endothelin A/B receptor antagonist bosentan. Two selective endothelin-A receptor antagonists, sitaxsentan and ambrisentan, are being developed. Finally, a randomised controlled trial has established the therapeutic efficacy of phosphodiesterase-5 inhibition with sildenafil, introducing a third signalling pathway to be targeted by the pharmacological treatment of PAH. Another phosphodiesterase-5 inhibitor, tadalafil, is already being evaluated. While all these treatments have markedly improved the lives of PAH patients, they have not offered yet a cure of the disease. Multi-drug approaches are now under evaluation, with more ambitious therapeutic goals. Alternative approaches with stem cells, RhoA-Rho-kinase inhibitors, platelet derived growth factor inhibitors and vasoactive intestinal peptides are being considered. PMID:17927481

    Objective To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. Materials and Methods A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Results Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Conclusion Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair. PMID:27587969

    Pediatric polyarteritis nodosa is rare systemic necrotizing arteritis involving small- and medium-sized muscular arteries characterized by aneurysmal dilatations involving the vessel wall. Aneurysms associated with polyarteritis nodosa are common in visceral arteries; however intracranial aneurysms have also been reported and can be associated with central nervous system symptoms, significant morbidity, and mortality. To our knowledge extracranial involvement of the vertebral arteries has not been reported but has the potential to be deleterious due to fact that they supply the central nervous system vasculature. We present a case of a 3-year-old Haitian boy with polyarteritis nodosa that presented with extracranial vessel involvement of his vertebral arteries. After thorough diagnostic imaging, including a bone scan, ultrasound, Magnetic Resonance Imaging/Angiography, and Computed Tomography Angiography, he was noted to have vertebral artery vasculitis, periostitis, subacute epididymoorchitis, arthritis, and myositis. He met diagnostic criteria for polyarteritis nodosa and was treated with cyclophosphamide, methylprednisolone, and tocilizumab, which resulted in improvement of his inflammatory markers, radiographic findings, and physical symptoms after treatment. To the authors' knowledge, this is the first report of vertebral artery vasculitis in polyarteritis nodosa as well as successful treatment of the condition using the combination cyclophosphamide and tocilizumab for this condition.

    We present a 17-y-old male who presented to the emergency room with left arm weakness along with slurred speech. On physical examination, he had stable vital signs with left facial weakness suggestive of lower motor neuron seventh nerve palsy. He was also noted to have a small pulsatile mass in the right infraclavicular region. Further questioning revealed that 3 mo earlier he had suffered blunt chest wall trauma during a football game with fracture-dislocation of the right clavicular head, which was managed conservatively. MRI of the brain showed right frontal cortical changes suggestive of infarct versus vasculitis or edema. Chest CT revealed a 2.5- to 3-cm pseudoaneurysm arising from the brachiocephalic artery, with thrombus formation, along with a surrounding 3 x 4.5 cm hematoma. The patient underwent a successful repair of the pseudoaneurysm with no further neurological sequelae. Traumatic pseudoaneurysm with thrombus formation is an extremely rare cause of stroke. It has been reported in association with the carotid artery, but to our knowledge, this is the first reported case with isolated innominate artery pseudoaneurysm. This case highlights the need for a broad differential when evaluating young patients with neurological deficits. PMID:19816975

    Purpose. The purpose of the study was to evaluate the angiographic findings and results of embolotherapy in the management of lumbar artery trauma. Methods. All patients with lumbar artery injury who underwent angiography and percutaneous embolization in a state trauma center within a 10-year period were retrospectively reviewed. Radiological information and procedural reports were reviewed to assess immediate angiographic findings and embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians as well as with chart review. Results. In a 10-year period, 255 trauma patients underwent abdominal aortography. Eleven of these patients (three women and eight men) suffered a lumbar artery injury. Angiography demonstrated active extravasation (in nine) and/or pseudoaneurysm (in four). Successful selective embolization of abnormal vessel(s) was performed in all patients. Coils were used in six patients, particles in one and gelfoam in five patients. Complications included one retroperitoneal abscess, which was treated successfully. One patient returned for embolization of an adjacent lumbar artery due to late pseudoaneurysm formation. Conclusions. In hemodynamically stable patients, selective embolization is a safe and effective method for immediate control of active extravasation, as well as to prevent future hemorrhage from an injured lumbar artery.

We present the case of a 57-year-old female patient with past history of emergent surgery for iatrogenic Type A dissection treated by supracoronary ascending aortic replacement. Four months after the initial surgery, a sternal fistula had formed and due to severe bleeding emergent reoperation was required. Imaging and pathology on admission revealed an infected pseudoaneurysm at the distal aortic prosthesis and mediastinitis with methicillin-resistant Staphylococcus aureus. Rescue surgery was performed by means of a two-stage approach, with extensive debridement, graft replacement and continuous antiseptic lavage in a first step and an omental wrapping of the new prosthesis in a second stage 24 hours later. During 10 years of follow-up, no recurrent infection occurred. The operative approach and general considerations for management of infected pseudoaneurysms are discussed. PMID:27069945

A 55-year-old patient presented with loss of sensation in the fingers and loss of peripheral pulsations in the right arm 4 days after right upper lobectomy for a pT2N1 moderately differentiated adenocarcinoma of the lung. Duplex examination and computed tomography were performed the same day and showed a subtotal stenosis of the right subclavian artery, which was caused by the surgical placement of a metal clip to mark the surgical boundary. Selective angiography was subsequently performed. Percutaneous transluminal angioplasty (PTA) successfully dilated the stenosis and pushed the clip off. Flow in the right subclavian artery (RSA) was completely restored as were neurology and peripheral pulses. In conclusion, arterial stenosis by a surgical (marking) clip may be feasibly treated with PTA.

    We report the successful treatment of dissection with stenosis of the carotid artery by stenting and aspiration of hematoma. A male patient, presenting with acute blurred vision and weakness and numbness of the right side of his body, was diagnosed with common carotid artery (CCA) dissection and severe stenosis of the internal carotid artery and CCA by digital subtraction arteriography and color Doppler ultrasonography (CDU). Two stents were separately implanted into the left internal carotid artery and CCA to restore blood flow and seal the opening of the dissection. The hematoma inside the CCA dissection was transcutaneously aspirated under CDU guidance after thrombolysis with tissue plasminogen activator. Three days after the operation, the dissection was still sealed. The patient was discharged 1 week later without any signs or symptoms. Follow-up examination at 70 days confirmed complete healing of the CCA dissection. Transcutaneous intradissection hematoma aspiration with CDU guidance may be applicable in treating arterial dissection, especially when conservative treatments cannot be expected to improve severe flow disturbances.

    Coronary embolization is a potentially fatal sequela of endocarditis. We report a case of Candida endocarditis with septic embolism to the left anterior descending coronary artery. This embolism was successfully treated with aspiration thrombectomy followed by balloon angioplasty. The treatment of acute coronary syndrome in the presence of septic embolism is controversial. Aspiration thrombectomy has been performed in this situation before, and it appears to be safer and more feasible than is thrombolysis or percutaneous transluminal angioplasty. PMID:25120402

    We report a case of acute stent recoil occurring after the stenting of an ostial left main coronary artery lesion. The marked recoil after high-pressure balloon inflation confirmed that the radial force of the first stent was unable to ensure vessel patency. The addition of a second stent provided the necessary support to achieve a good final result. This case illustrates a possible complication of aorto-ostial angioplasty that could be treated with double stenting. PMID:12499528

    Arterial mycotic pseudoaneurysms are a rare complication of pancreas transplantation. Rupture results in catastrophic hemorrhage with a high risk of mortality. Definitive management is complicated by an extensive arterial defect within a contaminated surgical field. Synthetic vascular grafts often fail due to subsequent graft infection whereas primary repair often results in arterial stenosis. Arterial ligation may be required to prevent exsanguination. A 41-year-old man, type 1 diabetic with associated renal failure, underwent successful simultaneous pancreas and kidney transplantation. He presented, 9 months following transplantation, with life-threatening rectal bleeding secondary to a ruptured mycotic pseudoaneurysm. This was successfully managed with a bovine pericardial patch (BPP) repair of the arterial defect and enteric diversion following graft pancreatectomy. He remains well with no vascular insufficiency 18 months following the procedure. A ruptured mycotic pseudoaneurysm following transplantation carries a significant risk of mortality and represents a surgical challenge as conventional techniques using synthetic materials often fail due to the contaminated field. A BPP offers good handling characteristics, excellent hemostatic properties and a favorable profile of infection risk in comparison with synthetic grafts. This case highlights its use as a treatment for a post-transplantation ruptured mycotic pseudoaneurysm. PMID:25131098

    Ruptured aneurysms of anterior inferior cerebellar artery (AICA) after radiotherapy for vestibular schwannoma (VS) are rare, and no definite treatment has been established for distal AICA pseudoaneurysms. We describe a 61-year-old man who underwent Gamma Knife surgery (GKS) for left VS. Follow-up magnetic resonance imaging (MRI) revealed partial regression of the tumor. Twelve years after GKS, he suffered from subarachnoid hemorrhage. Initial angiogram showed no vascular lesions; second left vertebral angiogram, 10 days after admission, demonstrated a pseudoaneurysm in the lateral pontine segment of the left AICA. The proximal portion of the AICA was occluded by a coil. Postoperative MRI revealed an infarction on the left side of the pons and brachium pontis. Although the patient suffered from mild postoperative cerebellar ataxia and facial and abducens nerve palsy, he was discharged 1 month postoperatively requiring no assistance with activities of daily living. Twelve months later, he recovered satisfactorily with a modified Rankin Scale grade of 1, and no recanalization of the aneurysm was found on MR angiography. Endovascular parent artery occlusion for ruptured aneurysms at distal AICA carries the risk of brain stem infarction, but should be considered when no other option is available such as after radiotherapy for VS.

    Between April 1978 and April 1981, 70 patients with hypertension and renal artery stenosis were treated by percutaneous transluminal arterial dilatation. Selection of the patients was based solely on arteriographic criteria. Arteriography after dilatation showed considerable widening of the stenosed area in all patients. In 65 patients the effect of treatment on the blood pressure was assessed during follow up periods of one to four years. In 14 of these patients the hypertension was cured, in 29 it was improved, and in 22 there was no change. Patients with fibromuscular lesions benefited distinctly more than did those with atheromatous stenosis, only one of the 21 patients with fibromuscular lesions showing no change as compared with 21 of the 44 patients with atheromatous lesions. The only serious complication encountered was microcholesterol emboli, which developed in two patients with severe atheromatous lesions of the aorta. In the atheromatous group age and overall renal function had no influence on the blood pressure response. In the subgroup of patients with a unilateral lesion the renal vein renin ratios and asymmetrical curves obtained by renography had only a very limited predictive value. In experienced hands percutaneous transluminal arterial dilatation is relatively safe, and this study suggests that it should be attempted in all patients with renal artery stenosis. Only in patients with severe atheromatosis of the aorta should the risk associated with the catheterisation be weighed against the 50% or so chance of benefit from the procedure. PMID:6223685

    Objective: To discuss the feasibility and safety of uterine artery chemoembolization in treating cesarean scar pregnancy (CSP). Methods: During the period between 1st of May 2009 and 17th of January 2014, uterine artery chemoembolization with methotrexate (MTX) and gelatin sponge was performed in 31 patients diagnosed with CSP in Xinqiao Hospital. Curettage of uterus was carried out within 24-48 hours after the procedure. Results: The success rate of bilateral uterine artery chemoembolization was 100%. The mean blood loss during curettage procedure was only 8.32±4.76 (2-20) ml. The mean time for serum β-HCG normalization was 33.81±17.47 (15-82) days, and the mean time for gestational sacs elimination was 29.52±20.93 (4-90) days. The mean time of hospital stay was 5.10±1.08 (4-8) days. Conclusions: No serious complications occurred. The uterine artery chemoembolization is an effective and safe treatment for CSP, which greatly reduces the necessity of hysterectomy. PMID:25932203

    Behcet's Disease (BD) is a rare disease, of unknown origin that generally causes an inflammation in the subcutaneous tissue, eyes and brain vessels, and related with the immune system, predominantly seen in male patients and the mean age at onset is mainly in the third decade. The aim of the study was to present our experiences with the cases of arterial pseudoaneurysms that we treated conservatively without surgical or radiological intervention. Eleven patients with Behcet's disease who developed arterial pseudoaneuryms and responsed to the medical treatment are included in the study. The operation requirement, the complication rates, and factors that influence morbidity and mortality are evaluated. The mean age of the patients was 29,5 (18-35) years. Nine of the patients were male and 2 were female. The mean period of hospitalization was 18 (11-34) days. Six patients redeveloped aneurysm during their follow-up. Three of these patients were treated with surgery. Five patients had no complication during an average of 20 months of follow-up period. Arterial pseudoaneurysm is a rare complication of Behcet's disease. Despite the good response to conservative treatment at the beginning period, the patients should be closely followed up and redevelopment of the aneurysm should be kept in mind. PMID:23482359

    Purpose: To evaluate the feasibility and short-term follow-up results of treating iliac aneurysms by the Cragg Endopro System 1 stent-graft. Methods: Nine lesions (two pseudoaneurysms and seven atherosclerotic aneurysms) were treated in eight patients by percutaneous implantation of a total of 10 stent-grafts. The procedure was followed by anticoagulation with heparin for 6 days, then antiplatelet therapy. Follow-up was by color Doppler ultrasound scan at 2 days and 3 months after the procedure for all patients, and by venous digital subtraction angiography and/or angio-CT up to 12 months later for four patients. Results: Initial clinical success rate was 100% and there were two minor complications. In one case the delivery system was faulty resulting in failure to deploy the stent-graft. An additional device had to be used. At 3-12 months all prostheses were patent but one patient (12.5%) had a minimal pergraft leak. Conclusion: Percutaneous stent-grafting with this device is a safe and efficacious treatment of iliac artery aneurysms.

    We report the singular case of an exceptionally large giant communicating artery aneurysm successfully treated with a direct surgical approach. The clinical presentation was a relatively short history of frontal headache. In the pre- and postcontrast CT scans the lesion mimicked an intracranial tumor. At surgery the intraluminal thrombus was partially removed with an ultrasonic surgical aspirator; the decompression allowed the isolation and subsequent temporary dipping of the tracts A1 and A2 of both the anterior cerebral arteries. It was then possible to complete the thrombectomy and to dip the neck of the aneurysm. The report emphasizes the indispensable role of MRI for the accurate diagnosis of giant intracranial aneurysms and the recent improvement of the surgical results concerning this category of aneurysms (mainly related to the present wider availability of technical surgical instrumentation).

    Summary Mirror image aneurysms of the distal anterior cerebral arteries (DACA) are rare. To the best of our knowledge this is the first case report of two patients with mirror image DACA aneurysms treated successfully with coil embolization. The association of aneurysms with anatomic variants has been extensively reported. We may speculate that the remnants of the failed regression of the supreme anterior communicating artery could lead to an increase in stress across their territorial bifurcation, leading to the development of mirror image DACA aneurysms. We found the endovascular treatment of mirror image DACA aneurysms to be feasible and effective. If possible, we suggest the treatment of both aneurysms in one procedure. PMID:23472723

    Arteriovenous fistulae (AVF) and grafts (AVG) for hemodialysis access generally provide good long-term solutions for the patient with end-stage renal disease. However, complications of both AVGs and AVFs are common and require a multimodality approach to maintain their patency and continued use. Commonly encountered problems include stenosis, thrombosis, aneurysm or pseudoaneurysm formation, rupture, and infection. Each needs to be addressed on a case-by-case basis. Outflow stenosis, often occurring within the cephalic arch in patients with a brachiocephalic fistula, may occur alone or be discovered in conjunction with other access problems. Pseudoaneurysm of the venous end generally arises from traumatic weakening of the vessel wall, often from repetitive venipuncture. More rare is the fracture of a previously placed stent. We present a case of stent fracture complicated by pseudoaneurysm formation with concomitant stenosis of the cephalic arch treated successfully with single-procedure placement of endovascular stent grafts.

    The Δ32-CCR5 deletion of the CCR5 receptor is protective toward coronary artery pathology and myocardial infarction. Maraviroc (MVC), a CCR5 antagonist, was recently introduced in the therapy of HIV infection; we evaluated whether this drug could modulate the atherosclerotic burden in aviremic PI-treated HIV-positive individuals who underwent MVC intensification. Thus, the effect of MVC on intima media thickness, arterial stiffness, metabolic parameters, pro-inflammatory cytokines, endothelial dysfunction, and microbial traslocation markers was analyzed in 6 aviremic PI-treated HIV-positive individuals and were compared to those obtained in 9 additional aviremic PI-treated subjects that were enrolled retrospectively from our outpatients cohort. MVC intensification resulted in a significant reduction in intima media thickness, pulse wave velocity and triglycerides compared to baseline. Notably, MVC was also associated with a significant reduction of IL-6, microbial translocation indexes, sICAM and sVCAM; these changes were maintained throughout the 6 months of MVC intensification. No significant modifications were observed in CD4 counts, HIV viral load, and cholesterolemia. Results herein support a role of CCR5 antagonists in reducing the cardiovascular risk in HIV-infection. The hampering of inflammation, microbial translocation and the improvement of endothelial function could justify the protective role of CCR5 antagonists on atherosclerotic burden. PMID:27352838

    A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child. PMID:10499389

    The aim of this case-control study was to evaluate carotid hemodynamic variables and traditional cardiovascular risk factors in women with Hashimoto thyroiditis (HT). The study group consisted of 31 females with HT on levothyroxine (L-T4) and 26 euthyroid women with HT without L-T4 matched for age and body mass index (BMI) as controls. Carotid intima-media thickness (CIMT), carotid extra-media thickness (CEMT), and pulsatility indexes in common carotid artery (PI CCA) and in internal carotid artery (PI ICA) were measured. BMI, waist circumference, lipid profile, fasting glucose and insulin levels, and parameters of thyroid function [TSH, free thyroxine (FT4) and antithyroperoxidase antibodies (TPOAbs)] were assessed. The study and the control groups did not differ in age, BMI, waist circumference, lipid profile, fasting glucose, and insulin levels. Results are expressed as median (IQR). Treated HT group had higher FT4 levels than nontreated [17.13 (5.11) pmol/l vs. 14.7 (2.27) pmol/l; p=0.0011] and similar TSH [1.64 (2.08) IU/ml vs. 2.07 (3.14) IU/ml; p=0.5915]. PI CCA and PI ICA were higher in the study group than in controls (p=0.0224 and p=0.0477, respectively). The difference remained statistically significant for PI ICA and PI CCA after adjustment for other variables (coefficient=0.09487; standard error=0.04438; p=0.037 and coefficient=0.1786; standard error=0.0870; p=0.0449, respectively). CIMT and CEMT were similar in both groups (p=0.8746 and p=0.0712, respectively). Women with HT on L-T4 replacement therapy have increased PI in common and internal carotid arteries than nontreated euthyroid HT patients. Therefore, it seems that hypothyroidism, but not autoimmune thyroiditis per se, influences arterial stiffness. PMID:25671800

A 75-year-old woman with non-tuberculous mycobacteriosis and pulmonary aspergillosis was admitted with recurrent hemoptysis despite repeated BAE. Considering the ineffectiveness of BAE with Spongel or polyvinyl alcohol, BAE with NBCA was selected. Immediate cessation of hemoptysis was obtained and it has not been seen for 2 years. Although NBCA is the most widely used liquid embolic material to treat brain aneurysm, arteriovenous malformations or gastric varices, there are only a few cases are reported in the treatment of hemoptysis. It seems to be a possible useful treatment for patients with repeated hemoptysis. PMID:19514507

    Among the variations of vertebral artery dissecting aneurysms (VDAs), VDAs involving the posterior inferior cerebellar artery (PICA), especially ruptured and high-risk unruptured aneurysms, are the most difficult to treat. Because the PICA is an important structure, serious symptoms may occur after its occlusion. Retained PICAs are prone to re-bleeding because VDAs are difficult to completely occlude. There is therefore confusion regarding the appropriate treatment for VDAs involving the PICA. Here, we used the PubMed database to review recent research concerning VDAs that involve the PICA, and we found that treatments for VDAs involving the PICA include (i) endovascular treatment involving the reconstruction of blood vessels and blood flow, (ii) occluding the aneurysm using an internal coil trapping or an assisted bypass, (iii) inducing reversed blood flow by occluding the proximal VDA or forming an assisted bypass, or (iv) the reconstruction of blood flow via a craniotomy. Although the above methods effectively treat VDAs involving the PICA, each method is associated with both a high degree of risk and specific advantages and disadvantages. The core problem when treating VDAs involving the PICA is to retain the PICA while occluding the aneurysm. Therefore, the method is generally selected on a case-by-case basis according to the characteristics of the aneurysm. In this study, we summarize the various current methods that are used to treat VDAs involving the PICA and provide schematic diagrams as our conclusion. Because there is no special field of research concerning VDAs involving the PICA, these cases are hidden within many multiple-cases studies. Therefore, this study does not review all relevant documents and may have some limitations. Thus, we have focused on the mainstream treatments for VDAs that involve the PICA. PMID:27429591

    Background Thrombolysis with rtPA is the only accepted drug therapy for acute ischemic stroke. Since acute cerebral stroke is so pervasive, newly developed recanalization methods have the potential for wide-ranging impacts on patient health and safety. We explored the efficacy and safety of Solitaire stent arterial embolectomy in the treatment of acute cardiogenic cerebral embolism. Material/Methods Between October 2012 and June 2015, 17 patients underwent Solitaire stent arterial embolectomy, either alone or in combination with rtPA intravenous thrombolysis, to treat acute cardiogenic cerebral embolism. Sheath placement time, vascular recanalization time, number of embolectomy attempts, and IV rtPA dose and time were recorded. Success and safety of the recanalization procedure, as well as clinical outcomes, were assessed. These results were compared to 16 control patients who were treated using only rtPA IV thrombolysis. Results Full recanalization of the occluded arteries was achieved in 15 (88.2%) of the Solitaire stent patients. NIH Stroke Scale scores of embolectomy patients improved by an average of 12.59±8.24 points between admission and discharge, compared to 5.56±5.96 in the control group (P<0.05). Glasgow Coma Score improvement between admission and discharge was also significantly higher in the embolectomy group (P<0.05). There was no significant difference in symptomatic intracerebral hemorrhage, high perfusion encephalopathy, incidence of hernia, or mortality between the 2 groups (P>0.05). Conclusions Solitaire stent embolectomy is a safe and effective alternative to simple venous thrombolytic therapy, and it can significantly improve short-term neurological function and long-term prognosis in acute cardiogenic cerebral embolism.

    Carotid-cavernous fistulas (CCFs) are an abnormal vascular shunt between the carotid artery and the cavernous sinus, and were traditionally classified into four subtypes based on the detailed fistulas anatomy and arterial supply. CCFs are frequently encountered in patients with traumatic skull base fractures. In this report, we present one such case caused by two head traumas. Computed tomography and digital subtraction angiography confirmed that this CCF arose from posterior communicating artery of the internal carotid artery, which is not included in the traditional Barrow et al’s categorization. The possible mechanisms include laceration of dural mater of posterior clinoid process and laceration or pseudoaneurysm formation of posterior communicating artery. This case was successfully treated with endovascular coil embolization. PMID:27099501

    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.

    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.

The patient underwent stenting to treat the SMA occlusion and subsequent deployment of a custom-designed fenestrated endovascular stent-graft to treat the PAU involving the CT origin. Follow-up at 6 months after device placement demonstrated no complications, and there was complete thrombosis of the PAU and patency of the two branch vessels.

    We report a case of acute ischemic stroke involving both the anterior and posterior circulation associated with a persistent primitive trigeminal artery (PPTA), treated by endovascular revascularization for acute basilar artery (BA) occlusion via the PPTA. An otherwise healthy 67-year-old man experienced sudden loss of consciousness and quadriplegia. Magnetic resonance imaging showed an extensive acute infarction in the right cerebral hemisphere, and magnetic resonance angiography showed occlusion of the right middle cerebral artery (MCA) and BA. Because the volume of infarction in the territory of the right MCA was extensive, we judged the use of intravenous tissue plasminogen activator to be contraindicated. Cerebral angiography revealed hypoplasia of both vertebral arteries and the presence of a PPTA from the right internal carotid artery. A microcatheter was introduced into the BA via the PPTA and revascularization was successfully performed using a Merci Retriever with adjuvant low-dose intraarterial urokinase. After treatment, his consciousness level and right motor weakness improved. Although persistent carotid-vertebrobasilar anastomoses such as a PPTA are relatively rare vascular anomalies, if the persistent primitive artery is present, it can be an access route for mechanical thrombectomy for acute ischemic stroke.

    We present a patient with Ehlers-Danlos syndrome type IV (EDS IV) with a carotid dissecting pseudoaneurysm causing severe carotid stenosis. This lesion was treated endovascularly. Unfortunately, the patient died of remote vascular catastrophes (intracranial hemorrhage and abdominal aortic rupture). This unique case illustrates the perils of endovascular treatment of EDS IV patients and the need for preoperative screening for concomitant lesions. It also shows that a dissecting pseudoaneurysm can feasibly be treated with a covered stent and that closure is effective using Angioseal in patients with EDS IV.

    Intra-arterial injection of sclerosants is a significant but uncommon complication of sclerotherapy that may result in extensive tissue necrosis and in rare cases digit or limb amputation. We have managed three cases in the past 10 years. One patient was referred for immediate treatment following intra-arterial injection of liquid polidocanol. The other two had undergone foam sclerotherapy with polidocanol and sodium tetradecyl sulphate, respectively. All patients were treated with a combination of oral steroids (prednisone 0.5-1 mg/kg) and systemic anticoagulants (enoxaparin 1.5 mg/kg daily subcutaneous injection). One case progressed to skin ulceration where prednisone was started five days after the adverse event and prematurely stopped after four weeks. The other cases did not progress to necrosis or other long-term sequelae. In these patients, prednisone was commenced immediately and slowly reduced over the following 12 weeks. The inflammation that follows ischemia plays a significant role in tissue necrosis and the immediate management of this adverse event may benefit from anti-inflammatory measures and in particular systemic steroid therapy unless contraindicated.

    A 48-year-old woman was diagnosed with idiopathic pulmonary arterial hypertension (PAH) and administered PAH-specific therapies, including bosentan. Four years after the initiation of treatment with bosentan, liver dysfunction appeared, and ambrisentan was substituted for bosentan. One-and-a half years later, a second episode of liver dysfunction occurred. The pathological findings of a liver biopsy specimen were not definitive, although drug-induced hepatotoxicity caused by ambrisentan was considered. However, the patient's liver dysfunction did not improve even after the discontinuation of ambrisentan. Finally, we diagnosed her with autoimmune hepatitis (AIH). Providing careful observation with a suspicion of AIH is important when treating PAH patients with autoantibodies. PMID:24694495

    Intracellular vesicular transport is shown to be dysfunctional in pulmonary arterial hypertension (PAH). However, the expression of intracellular vesicular transport proteins in PAH remains unclear. To elucidate the possible role of these proteins in the development of PAH, the changes in the expressions of N-ethyl-maleimide-sensitive factor (NSF), α-soluble NSF attachment protein (α-SNAP), synaptosome-associated membrane protein 23 (SNAP23), type 2 bone morphogenetic receptor (BMPR2), caveolin-1 (cav-1), and endothelial nitric oxide synthase (eNOS) were examined in lung tissues of monocrotaline (MCT)-treated rats by real-time polymerase chain reaction and western blot analysis. In addition, caspase-3, also examined by western blot analysis, was used as an indicator of apoptosis. Our data showed that during the development of PAH, the expressions of NSF, α-SNAP, and SNAP23 were significantly increased before pulmonary arterial pressure started to increase and then significantly decreased after PAH was established. The expressions of BMPR2 and eNOS were similar to those of NSF, α-SNAP, and SNAP23; however, the expression of cav-1 was down-regulated after MCT treatment. Caspase-3 expression was increased after exposure to MCT. In conclusion, the expressions of NSF, α-SNAP, and SNPA23 changed greatly during the onset of PAH, which was accompanied by abnormal expressions of BMPR2, cav-1, and eNOS, as well as an increase in apoptosis. Thus, changes in NSF, α-SNAP, and SNAP23 expressions appear to be mechanistically associated with the development of PAH in MCT-treated rats. PMID:25630652

    A 56-year-old man presented with a giant serpentine aneurysm arising from the middle cerebral artery (MCA) manifesting as right hemiparesis and motor aphasia. Magnetic resonance imaging and digital subtraction angiography identified the giant serpentine aneurysm arising from the MCA. The patient was treated surgically. Temporary clipping of the distal channel induced thrombosis in the vascular channel, and the thrombosis was aspirated with an ultrasonic suction device after superficial temporal artery-MCA anastomosis. This case shows that initial occlusion of the distal channel is effective to treat giant serpentine aneurysm. PMID:19246869

    Failure of a vascular closure device most commonly results in a hemorrhage or pseudoaneurysm formation. In this paper a rare case of severe acute limb ischemia following incorrect deployment of a clip-based closure device (Starclose SE, Abbott Vascular) in a 31-year-old woman is presented. Symptoms of acute limb ischemia occurred at the start of the ambulation, 6 h after completion of the procedure. Because of the severity of ischemia the patient was treated surgically, and limb perfusion was successfully restored. An attempt of closure of an inadvertently punctured narrow superficial femoral artery was identified as the cause of this complication. PMID:27458492

    Pseudoaneurysms of the ascending aorta are a rare complication of cardiac surgery. However, the poor prognosis associated with this condition if untreated makes early diagnosis and treatment important. We present the case of a 66-year-old woman who had undergone mitral valvuloplasty 12 days previously, who was admitted with a diagnosis of new-onset atrial fibrillation. The transthoracic echocardiogram showed a clot in the right atrium and anticoagulation was initiated, followed by antibiotic therapy. After further investigation, the patient was diagnosed with a pseudoaneurysm of the ascending aorta and underwent surgical repair, followed by six weeks of antibiotic therapy. She was readmitted six months later for an abscess of the lower sternum and mediastinum. After a conservative approach with antibiotics and local drainage failed, recurrence of a large pseudoaneurysm compressing the superior vena cava was documented. A third operation was performed to debride the infected tissue and to place an aortic allograft. There were no postoperative complications. PMID:24508151

    Pseudoaneurysm of the right ventricle outflow tract (RVOT) is a rare complication in pediatric cardiac surgery. We report a patient who developed a right ventricular pseudoaneurysm 8 months after RVOT enlargement using a pericardial patch for infundibular pulmonary stenosis. Our patient was born with severe pulmonary valvular stenosis and treated with percutaneous balloon valvotomy in the neonatal period. Six months later, she developed infundibular pulmonary stenosis, which required surgical resection of right ventricle infundibular trabeculations and bovine pericardial patch enlargement. The postoperative period was normal. She was readmitted to hospital 5 months later complaining of wheezing, coughing and shortness of breath. Echocardiography showed a huge aneurysmal dilatation of the outflow patch in connection with the right ventricular cavity. The patient underwent resection of the pseudoaneurysm and former patch, followed by interposition of a bovine jugular vein conduit between the RVOT and pulmonary bifurcation. The early postoperative period was uncomplicated. On echocardiography, no significant residual gradient was measured through the conduit and there was no insufficiency of the valve. RVOT reconstruction with patch enlargement, homograft or conduit implantation can be the origin of pseudoaneurysms. Although their incidence is rare, they are often asymptomatic before becoming quite large and causing compression symptoms as in our patient with respiratory complaints due to airway compression. It is important to follow up these patients closely, especially in the first year after surgery since most aneurysms develop within 6 months of surgery. PMID:20824590

    Mycotic aneurysms of the aorta are uncommon life-threatening lesions. Sporadic cases have been reported in adults after surgical intervention for native and recurrent coarctation of the aorta. We report a case of a rapidly progressive, large mycotic pseudoaneurysm in a 13-year-old boy 3 months after a bare-metal stent was used to treat native coarctation. The boy presented with slurred speech, bacteremia, and systemic septic embolization. During an emergency operation, the pseudoaneurysm was resected, and the infected aorta was replaced with an interposition graft. This rare complication may occur early or late after stent placement for coarctation of the aorta. PMID:27106463

    In general aneurysms of the pulmonary arteries are less frequent than intracranial, aortic or other vascular locations. Infectious causes include bacteria such as Staphylococcus sp and Streptococcus sp, mycobacteria, Treponema pallidium (syphilis) and rarely fungi. We report a 7 year old female with two right-sided parahilar pseudo-aneurysm of fungal origin with a prior history of ventricular septal defect. Pulmonary mycotic pseudo-aneurysms are very rare and require a high suspicion to diagnose. If a patient is still symptomatic for fever and cough for a long time, and consolidation on x-ray is not improving on antibiotics, contrast-enhanced computed tomography is indicated. It can be suspected that the "friable mass attached to ventricular septal defect patch" was a source of fungeal emboli to pulmonary arteries thus giving weight to the infective endocarditis etiology. A prior history of ventricular septal defect repair could favour fungal endocarditis. PMID:27238181

    Recently, we experienced a case where the diagnosis and management of a deep femoral artery rupture was delayed. This vascular complication occurred during the insertion of a distal interlocking screw of a proximal femoral nail for the fixation of an intertrochanteric femur fracture. A 79-year-old male patient was diagnosed with a right intertrochanteric fracture after a fall. We fixed the fracture with a proximal femoral nail (Zimmer® Natural Nail™ System). One day after the procedure, the patient complained of pain and swelling on the anteromedial side of his middle thigh followed by hypotension, anemia and prolonged thigh swelling. Computed tomography angiography was performed 7 days after the procedure. We found a pseudoaneurysm of the perforating artery caused by injury to the deep femoral artery and an intramuscular hematoma in the anterior thigh muscle. We successfully treated the pseudoaneurysm using coil embolization. Throughout the management of intertrochanteric femoral fractures, it is important to be aware and monitor signs and symptoms related to the possibility of blood vessel damage. When a patient presents with swelling and pain on the middle thigh and/or unexplained anemia postoperatively, the possibility that these symptoms are caused by an injury to the femoral artery must be considered.

    Endocarditis is uncommon in infants and is exceptionally related to Candida albicans on pulmonary banding. We report on a case in a 7-month-old infant who had pulmonary artery banding for a ventricular septal defect and who presented with candidal endocarditis. Banding was chosen because of the patient's poor trophic and unstable status, which could be risky for surgery involving extracorporeal circulation. A few weeks after the banding, the patient developed systemic Candida infection, which was treated successfully. At 7 months, cardiac failure appeared without fever or inflammatory signs. Cardiac echography showed that the banding was not protective as well as a hyperechogenic image on the pulmonary bifurcation. The angioscan showed a hypodense thrombus. Emergency surgery was performed consisting of pulmonary artery exploration, thrombectomy, and ventricular septal defect closure. The exploration showed a pulmonary artery perforation caused by the infected pseudoaneurysm and the migration of the banding into the pulmonary artery. The anatomopathologic analysis of the vegetation identified multisensitive Candida albicans. After surgery and prolonged antifungal treatment, progression was satisfactory. PMID:19525096

    The development of supra-celiac pseudoaneurysms following aorto-hepatic reconstruction during liver transplantation represents a major and surgically challenging complication. However, the use of endovascular stent grafts for the exclusion of aortic aneurysms is now a standard procedure with low morbidity and mortality. We demonstrate the successful endovascular repair of three cases of supra-celiac pseudoaneurysms, which developed after liver transplantation. A 40-yr-old woman, a 61-yr-old man, and a 45-yr-old woman underwent liver transplantation for end-stage liver disease. Between three months and five yr after the transplantation the patients developed large supra-celiac pseudoaneurysms leading to thrombosis of the hepatic artery and biliary complications. The stent graft implantation was uneventful, one endoleak Type I occluded spontaneously. There were no intervention-related complications. Unfortunately, one patient died one month after the procedure due to progressive liver failure and one died after five months due to multiple organ failure. One patient is still alive and in good condition. PMID:19659512

    This study investigates the respirability and efficacy of peptide-micelle hybrid nanoparticles as carriers for inhalational therapy of pulmonary arterial hypertension (PAH). CARSKNKDC (CAR), a cell-penetrating and lung-homing peptide, conjugated polyethylene glycol-distearoyl-phosphoethanolamine micelles containing fasudil, an investigational anti-PAH drug, were prepared by solvent evaporation method and characterized for various physicochemical properties. The pharmacokinetics and pharmacological efficacy of hybrid particles containing fasudil were evaluated in healthy rats and monocrotaline-induced PAH rats. CAR micelles containing fasudil had an entrapment efficiency of approximately 58%, showed controlled release of the drug, and were monodispersed with an average size of approximately 14 nm. Nuclear magnetic resonance scan confirmed the drug's presence in the core of peptide-micelle hybrid particles. Compared with plain micelles, CAR peptide increased the cellular uptake by approximately 1.7-fold and extended the drug half-life by approximately fivefold. The formulations were more prone to accumulate in the pulmonary vasculature than in the peripheral blood, which is evident from the ratio of the extent of reduction of pulmonary and systemic arterial pressures. On the whole, this study demonstrates that peptide-polymer hybrid micelles can serve as inhalational carriers for PAH therapy. PMID:25266507

    A 36-year-old man, who had undergone thoracoscopic anterior spinal fusion using the plate system and posterior screw fusion three months previously, presented to our hospital with left flank pain and fever. Computed tomography indicated the presence of a psoas muscle abscess. However, after two days of percutaneous catheter drainage, a mycotic abdominal aortic pseudoaneurysm was detected via computed tomography. We performed in situ revascularization using a prosthetic graft with omental wrapping. Methicillin-resistant Staphylococcus aureus was identified on blood and pus culture, and systemic vancomycin was administered for one month. Although the abscess recurred, it was successfully treated with percutaneous catheter drainage and systemic vancomycin administration for three months, without the need for instrumentation removal. The patient remained asymptomatic throughout two years of follow-up. PMID:26665118

    In this article we present an unusual case of hepatic artery aneurysm bleeding due to a hepatic artery thrombosis after liver transplantation. The patient developed a recurrent hepatic artery thrombosis leading to severe graft failure in four consecutive liver transplantations. While being evaluated for a fifth transplant, stabilization of the clinical situation was attempted by interventional therapy. The first intervention was to place a stent into the hepatic artery to prevent further ischemic damage. This failed to improve graft function, but unfortunately led to the development of a pseudoaneurysm at the distal end with a subsequent rupture into the biliary tree. Bleeding was treated successfully by direct puncture and coil embolization of the aneurysm. In addition, the patient demonstrated a hemodynamically relevant portal vein stenosis on the CT scan. Stenting of the portal vein markedly improved graft function. After extensive investigations, a paroxysmal nocturnal hemoglobinuria was found to be the underlying cause of the recurrent hepatic artery thrombosis. Here we suggest that hepatic artery aneurysm bleeding is a rare but potentially fatal complication that can be successfully treated by percutaneous coil embolization. Additionally, we propose that stenting of the portal vein can lead to a significant improvement of the graft perfusion even though the hepatic artery remained occluded.

    Background: Treatment of anterior choroidal artery (AChA) aneurysms with endovascular coiling or surgical clipping may increase the risk of ischemic complications owing to the critical territory supplied by the AChA. We analyzed the surgical results of endovascular coiling and surgical clipping for AChA aneurysms performed in a single institution, as well as the role of indocyanine green-videoangiography (ICG-VAG) and motor-evoked potential (MEP). Methods: We analyzed 50 patients (51 aneurysms; 21 men, 29 women; mean age: 58 years) including 25 with subarachnoid hemorrhage treated with endovascular coiling or surgical clipping between April 1990 and October 2013. The complication rates and clinical outcomes of the coil group (mean follow-up: 61 months) and the clip group (mean follow-up: 121 months) were analyzed with a modified Rankin scale. Results: The overall clinical outcome of the coil group (95%) was better than that of the clip group (85%). Especially, the outcomes in the coil group were better in the first investigated period (1990–2007) (P < 0.05). However, after the introduction of ICG-VAG and MEP, the outcomes in the clip group improved significantly (P = 0.005), and treatment-related complications decreased from 20 to 4.7%. Eleven aneurysms (coil group: 8, clip group: 3) showed small neck remnants but no remarkable regrowth, except for 1 case during the mean follow-up period of 91 months. Conclusions: Surgical clipping of AChA aneurysms has become safer because of ICG-VAG and MEP monitoring. Coiling and clipping of AChA aneurysms showed good and comparable outcomes with these monitoring methods.

    Abulia refers to a pathological deficit of willpower. Disruption of frontal-subcortical-mesolimbic circuits caused by lesions in certain central nervous system structures has been associated with abulia. Given the neurobiological link between the dopaminergic reward system and the psychological phenomenon of motivation, it has been speculated that modulating dopaminergic neurotransmission will potentially alter the clinical presentation of abulia. We present a case of abulia S/P right middle cerebral artery, treated successfully with olanzapine. PMID:25384076

    This study aims to explore the treatment methods for patients with abdominal aortic aneurysms (AAAs) that required occlusion of the openings of the bilateral internal iliac arteries (IIAs) in endovascular aneurysm repair (EVAR) and to evaluate the efficacy of these treatments. Four patients with AAA were treated with endovascular aneurysm repair (EVAR) and the crossover chimney technique in the bilateral internal iliac arteries (IIAs). We inserted and released the abdominal aortic stent as usual and implanted the bypass stent graft simultaneously. The intraoperative immediate angiography showed complete isolation of the AAA and patency of the bypass. One month after surgery, it showed contrast engorgement in the bypass stent in three patients. The IIA on the bypass side and its branches had good developing. Another case in which we utilized a COOK stent, occlusion started at the opening of the bypass stent, with no occurrence of other complications. For patients in whom AAAs involve bilateral iliac arteries and the openings of the bilateral IIAs need to be occluded, EVAR and a crossover chimney technique can protect the unilateral IIA.

    A 17-year-old patient underwent total arch replacement for aortic arch aneurysm due to vascular Behcet's disease (BD). Follow-up computed tomography, performed 6 months after the operation, demonstrated pseudoaneurysm formation at the proximal anastomotic site. We performed endovascular treatment and used a short stent graft that was originally designed for abdominal aortic aneurysm. To avoid the occlusion of the coronary or brachiocephalic artery (BCA) due to stent graft migration, we used right ventricular rapid pacing and BCA ballooning. Thus, we believe that endovascular treatment can be used for anastomotic complications in the ascending aorta after open surgery for connective tissue disorders including BD. PMID:27174345

    The prognosis for patients with unresectable intrahepatic cholangiocarcinoma(ICC) is extremely poor. Case 1 was a 65- year-old woman who had an ICC of 9 cm in diameter (mass-forming type) in the right lobe with portal trunk invasion. She was treated with hepatic arterial infusion chemotherapy[cisplatin(CDDP)/5-fluorouracil(5-FU)/l-leucovorin(l-LV)] and radiation therapy (total dose, 50 Gy). After 6 months, abdominal computed tomography (CT) revealed that the tumor had regressed. She survived for 7 years without recurrence of the ICC; subsequently, she died of peritoneal cancer. Case 2 was a 59-year-old woman who had an ICC of 8 cm in diameter (mass-forming type) in the left lobe with lymph node metastasis in the hepatoduodenal ligament; the right hepatic artery was involved by the metastatic lymph nodes. She was treated with hepatic arterial infusion chemotherapy(CDDP/5-FU/l-LV) and radiation therapy(total dose, 30 Gy). After 10 months, abdominal CT revealed that the tumor had disappeared, but paraaortic and mediastinal lymph node metastases were detected. She was therefore treated with systemic chemotherapy. Treatment with systematic chemotherapy enabled her to survive for over 5 years with a good performance status. PMID:23267958

    Pseudoaneurysms are vessel wall ruptures, that are often mistaken for deep vein thrombosis (DVT). A middle-aged man presented with right leg pain, swelling and erythema. His history was significant for persistent Staphylococcus aureus bacteraemia. Ultrasound revealed subacute DVT and laboratory parameters were suggestive of sepsis. He was started on intravenous heparin and antimicrobials. Owing to persistent anaemia despite blood transfusion, MRI of the right thigh was obtained. It revealed a 13×17 cm superficial femoral artery infected mycotic pseudoaneurysm (MPA) with a fresh haematoma. The patient underwent arterial ligation and extensive debridement. Intraoperative cultures revealed daptomycin-resistant vancomycin-intermediate S. aureus (VISA) and he was managed with 6 weeks of intravenous ceftaroline. MPAs are most common in the femoral artery and form <1% of aneurysms. Therapy involves surgical debridement and prolonged antimicrobials. VISA causing MPA is associated with worse outcomes. We report the first time use of ceftaroline in the management of a VISA MPA. PMID:25833910

    The role of thrombolysis in brain ischemia in patients with atrial myxoma is unknown. A patient with acute brain ischemia and previously undiagnosed atrial myxoma recanalized an occluded middle cerebral artery with intra-arterial thrombolysis. Arterial occlusion from presumed myxoma may be amenable to fibrinolysis. Angiography before treatment in patients with atrial myxoma excludes a myxomatous pseudoaneurysm and permits site-specific thrombolytic instillment. PMID:9270611

    OBJECT The revascularization technique, including bypass created using the external carotid artery (ECA), radial artery (RA), and M2 portion of middle cerebral artery (MCA), has remained indispensable for treatment of complex aneurysms. To date, it remains unknown whether diameters of the RA, superficial temporal artery (STA), and C2 portion of the internal carotid artery (ICA) and intraoperative MCA blood pressure have influences on the outcome and the symptomatic watershed infarction (WI). The aim of the present study was to evaluate the factors for the symptomatic WI and neurological worsening in patients treated by ECA-RA-M2 bypass for complex ICA aneurysm with therapeutic ICA occlusion. METHODS The authors measured the sizes of vessels (RA, C2, M2, and STA) and intraoperative MCA blood pressure (initial, after ICA occlusion, and after releasing the RA graft bypass) in 37 patients. Symptomatic WI was defined as presence of the following: postoperative new neurological deficits, WI on postoperative diffusion-weighted imaging, and ipsilateral cerebral blood flow reduction on SPECT. Neurological worsening was defined as the increase in 1 or more modified Rankin Scale scores. First, the authors performed receiver operating characteristic curve analysis for continuous variables and the binary end point of the symptomatic WI. The clinical, radiological, and physiological characteristics of patients with and without the symptomatic WI were compared using the log-rank test. Then, the authors compared the variables between patients with and without neurological worsening at discharge and at the 12-month follow-up examination or last hospital visit. RESULTS Symptomatic WI was observed in 2 (5.4%) patients. The mean MCA pressure after releasing the RA graft (< 55 mm Hg; p = 0.017), mean (MCA pressure after releasing the RA graft)/(initial MCA pressure) (< 0.70 mm Hg; p = 0.032), and mean cross-sectional area ratio ([RA/C2 diameter](2) < 0.40 mm [p < 0.0001] and [STA/C2

    A 20-year-old man was admitted to the emergency department after falling 15 m onto the roof of a car and landing on his back. Imaging by computed tomography (CT) showed delayed perfusion of the right kidney and no excretion of contrast from that kidney on delayed images. Angiography confirmed a localized intimal dissection in the right main renal artery. We inserted a balloon-expandable stent using a transfemoral approach to successfully repair the dissection. At 4 year follow-up, Doppler ultrasound of the right renal artery and renal scintigraphy demonstrated preserved function of the right kidney. Our findings support endovascular stenting as a safe, effective and efficient treatment for blunt renal artery injury.

    A 75-year-old man with a history of diabetes mellitus and hypertension was suffered from dizziness and vomiting and brought to the near-by hospital. MRI showed cerebellar infarction due to right vertebral artery stenosis. Despite best medical treatment, the infarction progressed day by day and he was transferred to our hospital five days later. Neurological examination showed mild disturbance of consciousness and right hemiparesis. Right vertebral angiography revealed high-grade stenosis accompanied with atherosclerosis at the V3-V4 portion. Percutaneous transluminal angioplasty(PTA)was performed with 2.5mm×14mm balloon with 6 atm dilation. Postoperative course was uneventful and no further stroke occurred after the treatment. PTA was effective for vertebral artery stenosis manifested with progressing stroke. The indication of stent placement for the cerebral artery should be prudent. PMID:27166843

    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

    Some challenges have been detected when there are long and complex lesions of femoropopliteal arterial occlusive disease, even with descriptions of the retrograde pedal approaches. The aim of this article is to describe the retrograde proximal anterior tibial artery access for treatment of femoropopliteal segment occlusion when antegrade recanalization failed (retrograde recanalization and rearranging the system into an antegrade position). Technical and clinical success was achieved in 100% of 4 cases, with an improvement of at least 2 Rutherford classes. Minor complication, small hematoma in an anterior compartment of the limb, occurred in 1 patient. No sign of compartmental syndrome was observed. PMID:26902943

    Complete dehiscence of a composite aortic valve graft with pseudoaneurysm formation is a rare complication following aortic root replacement. This complication often takes place in the setting of acute graft infection and accompanies symptoms of heart failure, valve insufficiency or sepsis. We present a delayed, asymptomatic presentation of this complication in a young man with distant history of aortic root replacement and medically treated prosthetic valve endocarditis a year postoperatively. He had been non-adherent to warfarin over 10 years, but otherwise maintained a healthy life. After being lost to follow-up, he re-presented 12 years after the initial operation with new-onset seizures. Echocardiogram revealed complete dehiscence of a composite valved conduit at the proximal anastomosis site with a resultant large pseudoaneurysm. The patient underwent an urgent re-operation with resection of the pseudoaneurysm and insertion of a tissue valved conduit. He had an uncomplicated postoperative recovery and promised close follow-up on discharge. PMID:27530875

    Isolated middle cerebral artery dissection is a rare clinical entity, with descriptions limited to a few case reports and case series. Symptomatic dissection in the anterior circulation can present as an ischemic stroke in a young population; however, it is rarely associated with subarachnoid hemorrhage. We describe a young patient who presented with acute headache from a subarachnoid hemorrhage that was ultimately determined to be due to a vascular dissection in the middle cerebral artery. The initial angiogram showed vascular irregularities in this area with stenosis. Repeat imaging 4 days after presentation identified a pseudoaneurysm proximal to the stenosis. The patient was successfully treated with a self-expanding nitinol stent and followed up with serial angiography during postoperative recovery in the hospital; additional angiograms were performed approximately 1 and 6 months after treatment. Serial angiograms demonstrated incremental healing of the dissection. The patient was discharged and remains neurologically intact at the 6-month follow-up. PMID:25854687

    2014-01-01

    Background: Fusiform aneurysms of cerebellar arteries are rare. Different surgical techniques to address these challenging lesions have been described, and their application depends on whether the goal is to maintain the flow in the parent vessel or to occlude it. Case Description: The authors reported a case of a fusiform aneurysm located in the lateral pontomesencephalic segment of the superior cerebellar artery (SCA) in a 32-year-old man who presented with subarachnoid hemorrhage. The patient was subjected to aneurysm trapping followed by a bypass between the superficial temporal artery (STA) and SCA and had an uneventful recovery. Conclusions: Although only a few cases of fusiform aneurysms in the supracerebellar artery have been reported in the literature, the treatment strategies adopted were diverse. In selected cases of patients in good neurological condition with ruptured fusiform aneurysms at the proximal segments of SCA and who have poor evidence of collateral supply, the possibility of a STA-SCA bypass with aneurysm trapping must be considered. A review of the current treatment modalities of this pathology is also presented. PMID:25071936

    Fetal brain perfusion is supplied by the primitive dorsal aorta anteriorly, longitudinal neural arteries posteriorly, and anastomotic transverse segmentals. Most notable of these connections are the primitive trigeminal, otic, hypoglossal, and proatlantal arteries. With cranial-cervical circulatory maturation and development of the posterior communicating segments and vertebro-basilar system, these primitive segmental anastomoses normally regress. Anomalous neurovascular development can result in persistence of these anastomoses. Due to its territory of perfusion, the persistent primitive hypoglossal artery (PPHA) is associated with vertebral artery and posterior communicating artery hypoplasia or aplasia. As a consequence, primary blood supply to the hindbrain comes chiefly from this single artery. Although usually clinically silent, PPHA is susceptible to common cerebrovascular disorders including athero-ischemic disease and saccular aneurysmal dilation to name a few. We present a case of transient ischemic attack in a patient with a PPHA and proximal atherosclerotic disease treated by endovascular stenting. PMID:26929891

    Background Giant cell tumor of the sacrum, especially involving the sacroiliac joint, is rare, but is particularly challenging to treat. The long term outcome of a patient was studied with giant cell tumor involving the sacroiliac joint treated with selective arterial embolization and curretage. Method One patient with giant cell tumor involving the sacroiliac joint was treated with selective arterial embolization and curettage in our hospital in October 2002. The curettage and bone grafting was done after two times of selective arterial embolization;1600 ml of blood were transfused and no complications developed during the operation. Results At the final follow-up of 9 years after the operation, no local recurrence and metastasis developed and she retained normal activity in daily life. Conclusion We think it is an optimal treatment for giant cell tumor involving the sacroiliac joint, with repeated selective arterial embolization and curettage, which has the advantage of less injury, less blood loss and fewer complications.

    Women with gestational diabetes mellitus (GDM) are at high risk of subsequently developing type 2 diabetes mellitus which is an important cardiovascular risk factor. We have evaluated whether preclinical morphological and functional arterial changes are present in GDM. Diameter, intima-media thickness (IMT), intima-media cross-section area (IMCSA) and elasticity features (compliance, distensibility coefficient, circumferential strain, stiffness index (SI) α and β, incremental elastic modulus) of the common carotid arteries (CCA) were studied in the 3rd trimester in 25 women with GDM, and 17 normal pregnant women matched for age and body mass index using an ultrasonographic vessel wall-movement tracking system and applanation tonometry. Mean IMT, IMCSA and SI α tended to be larger, whereas compliance was smaller in women with GDM but none of these differences were significant. Serum glucose (4.99 ± 0.51 vs. 4.79 ± 0.61 mmol/L, p=0.37) and HbA1c (5.33 ± 0.27 vs. 5.36 ± 0.47 mmol/L, p=0.85) proved normoglycemia in both groups. In conclusion, by the combination of methods we applied in this case control study, neither morphological nor functional characteristics of large elastic arteries differ significantly between well-treated normoglycemic women with GDM and non-diabetic pregnant women in the 3rd trimester.

    Use of endovascular means is gaining ever greater acceptance in the treatment of aorto-iliac aneurysms. Especially, the treatment of patients with common iliac aneurysms (CIAs) may be very challenging due to the complexity of the underlying disease with often involvement of the hypogastric artery. Additionally, the variety of endovascular therapeutic options such as the use of iliac branch devices, parallel grafts, the bell-bottom technique or coil embolization of the hypogastric artery and overstenting of the origin represents significant limitation regarding the presentation of a clear and robust endovascular therapeutic algorithm. Aim of the present article was the demonstration of the institutional experience with the endovascular management of CIAs in order to provide a clinical recommendation and algorithm. PMID:27406396

    The patient was a 50-year-old woman who suffered from gastric discomfort. She was first diagnosed as intrahepatic cholangiocarcinoma with hepatic, paraaortic lymphnodal and bone metastasis. Initial systemic chemotherapy using gemcitabine (GEM) and 5-FU failed to control the disease activity. Then she was given GEM and cisplatin (CDDP) combination chemotherapy. The response was assessed as stable disease (SD), but grade 4 leukopenia was seen. Then systemic therapy using GEM, and hepatic arterial infusion therapy with CDDP, l-leucovorin and 5-FU were continued biweekly. Partial response (PR) was achieved six months later, and her disease status was maintained as SD. This hepatic arterial infusion chemotherapy would be safe and feasible as therapy for inoperable intrahepatic cholangiocarcinoma. PMID:17108736

    PubMed Central

    2015-01-01

    A 66-year-old man with a history of coronary artery disease was evaluated due to ventricular tachycardic (VT) storm. The patient continued to have frequent recurrences of VT despite treatment with amiodarone and lidocaine. Since the ventricular arrhythmia could be related to myocardial ischemia related to a chronic total occlusion (CTO) of the right coronary artery, the patient underwent successful percutaneous coronary intervention of the CTO, followed by implantable cardioverter defibrillator implantation. He had no further episodes of VT during his hospital stay. After 9 months of follow-up, he had no further chest pain or clinically apparent recurrent ischemia. Interrogation of his defibrillator has shown brief nonsustained episodes of ventricular tachycardia, but the patient has not required delivery of a shock. The temporal association between treatment of the CTO and resolution of the VT, as well as the lack of recurrence of sustained VT, suggest a causative link between underlying ischemia produced by a chronically occluded coronary artery and provocation of VT and lend supportive evidence to this treatment approach.

    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

    The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery. PMID:26072086

    Objectives. A symptomatic renal pseudoaneurysm (RPA) is a severe complication after open partial nephrectomy (OPN). The aim of our study was to assess incidence and risk factors for RPA formation. Furthermore, we present our management strategy. Patients and Methods. Clinical records of consecutive patients undergoing OPN were assessed for surgical outcome and postoperative complications. Renal masses were risk stratified for tumor complexity according to the PADUA score. Uni- and multivariate analysis for symptomatic RPAs were performed using the t-tests and logistic regression. Results. We identified 233 patients treated with OPN. Symptomatic RPAs were observed in 13 (5.6%) patients, on average 14 (4–42) days after surgery. Uni- and multivariate analysis identified tumor complexity to be an independent predictor for symptomatic RPAs (p = 0.004). There was a significant correlation between RPAs and transfusion and the duration of stay (p < 0.001 and p = 0.021). Symptomatic RPAs were diagnosed with CT scans and successfully treated with arterial embolization. Discussion. Symptomatic RPAs are not uncommon after OPN for high-risk renal masses. A high nephrometry score is a predictor for this severe complication and may enable a risk-stratified followup. RPAs can successfully be located by CT angiography, which enables targeted angiographic treatment. PMID:26539549

    Gelatin sponge particles are commonly used in the conventional transarterial chemoembolization (c-TACE) as an adjuvant embolizing agent for hepatocellular carcinoma (HCC). However, there are few reports regarding the clinical applications of gelatin sponge microparticles (GSMs) as a main embolizing agent in the treatment of HCC. This retrospective study aim to evaluate the efficacy and safety of patients with Barcelona Clinic Liver Cancer (BCLC) stage B HCC treated with intra-arterial injection of 350 to 560 μm GSMs mixed with anticancer agents.Twenty-four patients with unresectable BCLC stage B HCC without any prior treatment underwent transarterial chemoembolization with gelatin sponge microparticles (GSMs-TACE) of diameter 350 to 560 μm mixed with lobaplatin. The mixture was injected into tumor-feeding arteries until the sluggish flow in selective artery. Safety was measured by assessing complication rate, and efficacy was reflected by assessing response to mRECIST therapy and overall survival. The survival rate was calculated using the Kaplan-Meier method.All 24 BCLC stage B HCC patients showed good tolerance to the procedure. The mean follow-up period was 27 months and mean number of TACE treatments per patient was 3.7 sessions (range 1-10) during the follow-up period. Postprocedure complications were mild and treated by symptomatic treatment. Six months and 1 year overall survival rates were 100% and 87.5%, respectively. Overall median survival time was 25 months (95%CI: 21.06-28.95 months).GSMs-TACE is a safe and effective method for BCLC stage B HCC patients. PMID:26717358

    Pulmonary tuberculosis is an opportunistic infection that can be reactivated in immunocompromised conditions, for example, in malignancy or after liver transplantation. Hepatocellular carcinoma (HCC) has a high mortality rate because it is frequently diagnosed at an advanced stage. Although surgical resection is the established curative measure for HCC, it is only feasible for early-stage HCC. Transcatheter arterial chemoembolization (TACE) is the most common treatment modality for patients with unresectable HCC. However, repeated TACE sessions and, occasionally, the tumor itself can further impair the reserve hepatic function and immunity. We report 3 recent cases of HCC with reactivation of pulmonary tuberculosis after TACE. PMID:22761986

    Cardiopulmonary abnormalities are often present in patients with liver diseases. We herein report a case of congenital portosystemic shunts complicated by hepatopulmonary syndrome (HPS) and portopulmonary hypertension (PoPH). A 57-year-old woman complained of dyspnea and was subsequently diagnosed with HPS and PoPH caused by congenital portosystemic shunts. Although shunt closure by transcatheter embolization was successfully performed, her dyspnea worsened and pulmonary artery pressure and pulmonary vascular resistance elevated. Conventional vasodilator therapy was started, resulting in an improvement of pulmonary hypertension (PH). In some patients with congenital portosystemic shunts, shunt closure could exacerbate PH, and vasodilator therapy may be effective. PMID:27580545

    Introduction The placement of a Swan-Ganz catheter into the pulmonary artery may lead to a number of complications (2–17%). In less than 0.2% of cases Swan-Ganz catheterization results in serious vascular damage – pulmonary artery rupture (PAR). This paper presents two distinct forms of iatrogenic PAR treated endovascularly using different vascular devices. Aim To evaluate the effectiveness of endovascular treatment and the application of different types of vascular devices in the management of pulmonary artery rupture caused by Swan-Ganz catheterization. Material and methods In this retrospective study we evaluated 2 patients in whom Swan-Ganz catheter application was used for perioperative monitoring and resulted in pulmonary artery rupture. This complication was treated endovascularly by means of interventional cardiology. Results We report the cases of 2 patients with a pulmonary artery pseudoaneurysm formed in the perioperative period. In case 1, a single, 4-loop, 3 mm diameter coil was implanted. In case 2, a 5 mm Amplatzer Vascular Plug IV was applied. In both cases, the endovascular approach resulted in total occlusion of the feeding artery and reduced further extravasation of the blood. Conclusions Despite its extremely low incidence, iatrogenic PAR is a serious, life-threatening complication of Swan-Ganz catheterization that requires urgent attention. Among available methods of treatment, percutaneous embolization is a relatively quick, safe, accurate and highly effective alternative to traumatizing surgery. PMID:27279873

    In a 75-year-old man, a growing vertebral artery aneurysm at the C3/4 intervertebral level was found at postoperative evaluation of cervical abscess, which was diagnosed as a complication of sepsis subsequent to cholangitis. Even after a successful antibiotic treatment and a surgical drainage, the aneurysm grew enough to cause compression of esophagus and trachea. The aneurysm was judged to be infection-related, based on the clinical course and the anatomical vicinity to the abscess. Following a dual antiplatelet treatment (clopidogrel 75 mg and aspirin 100 mg per day) for a week, the patient underwent endovascular treatment of the aneurysm with a stent-graft. Postoperative angiography showed complete obliteration of the aneurysm with preserving patency of the vertebral artery. A dual antiplatelet treatment was continued for 6 months and was changed to a single antiplatelet treatment (clopidogrel 75 mg per day) thereafter. Neither recurrence of the aneurysm nor stent-graft infection was observed for 4 years of follow-up. This case illustrates the potential use of a stent-graft in the treatment of an infected aneurysm.

    Perventricular ventricular septal defect (VSD) closure has been adopted as a therapeutic option for selected patients with muscular VSDs. This technique may combine some of the advantages of surgical and interventional techniques. Complication rates have been low: only one case of procedure-related left ventricular (LV) pseudoaneurysm has been documented. We report the surgical repair for a LV pseudoaneurysm after perventricular VSD device closure. PMID:24131474

    Purpose. To evaluate the safety and efficacy of stent placement for extracranial and intracranial arterial dissections. Methods. Eighteen patients underwent endovascular treatment of carotid and vertebral dissections using intraluminal stent placement. Five patients with arterial dissection were treated, 2 using one insertion of a single stent and 3 using placement of two stents. Patients with a dissecting aneurysm were treated as follows: 7 patients with insertion of one stent, 4 with placement of two stents, and 2 by stent-assisted Guglielmi detachable coil embolization. In the 18 patients in whom stenting was attempted, the overall success in reaching the target lesion was 94.4%. Of the 17 patients treated with stents, stent release and positioning were considered optimal in 16 (94%) and suboptimal in one (6%). In patients who underwent a successful procedure, all parent arteries were preserved. There were no instances of postprocedural ischemic attacks, new neurologic deficits, or new minor or major strokes prior to patient discharge. In follow up, all patients were assessed, using the modified Rankin scale, as functionally improved or of stable clinical status. The reduction in dissection-induced stenosis or pseudoaneurysm, the patency rate obtained at follow-up, and the lack of strokes (ischemic or hemorrhagic) suggest that stent placement offers a viable alternative to complex surgical bypass or reconstructive procedures. The long-term efficacy and durability of stent placement for arterial dissection remain to be determined in a larger series.

    A 35-year-old farmer presented with complaints of pain in the right upper limb for 1 month and bluish discoloration of the right-hand finger tips with tingling and numbness. He sustained injury to the right upper limb while lifting a heavy object 1 mo previously. There was an ovoid swelling of 4 × 2 cm on the medial aspect of the right arm, 12 cm above the medial epicondyle at the level of the armpit with visible pulsations. There was distal neurovascular deficit. Duplex scan of the right upper limb arterial system revealed a pseudoaneurysm of the proximal right brachial artery, with dampened monophasic flow in the ulnar artery and no flow in the radial artery. Spiral computed tomography angiogram showed the presence of an echogenic periarterial lesion in the proximal brachial artery suggestive of pseudoaneurysm or an extrinsic compression by hematoma. Distal brachial artery was found to have filled with thrombus, with non-opacification of the radial and the distal ulnar artery. The patient was posted for excision of the aneurysmal arterial segment. A 5-cm-long reversed segment of vein graft was interposed in between the cut ends of the brachial artery. Histopathology: Specimen shows a part of the vessel wall composed of intimal, medial, and adventitial layers with intraluminal thrombus showing evidence of recanalization suggestive of true aneurysm of the brachial artery.

    Nanoscale topography in improving vascular response in vitro was established previously on various titanium surfaces. In the present study different surface nanotopographies that is different diameters of titanium dioxide (TiO2 ) nanotubes (NTs) were fabricated by electrochemical anodization and conditioned with highly reactive gaseous oxygen plasma. The morphology of different diameter NTs was studied by scanning electron microscopy and atomic force microscopy, while changes in chemical composition on the surface before and after plasma treatment were determined by X-ray photoelectron spectroscopy. Performance of human coronary artery endothelial cells (HCAEC) on those conditioned surfaces was studied in regard to cell proliferation, released IL-6 protein and immunofluorescence microscopy (IFM). We show that HCAEC function is dependent on the diameter of the TiO2 NTs, functioning far less optimally when bound to 100 nm TiO2 NTs as compared to Ti foil, 15 nm NTs or 50 nm NTs. There were improved, morphological cell shape changes, observed with IFM, between HCAEC growing on oxygen-rich plasma-treated versus nontreated 100 nm NTs. These endothelialized conditioned Ti nanosurfaces could elucidate optimization conditions necessary for vascular implants in coronary arteries. © 2016 Wiley Periodicals, Inc.

    Whether biomarkers associated with cardiovascular disease risk also predict incident diabetes mellitus (DM) is unknown. Our objective was to determine if a panel of 18 biomarkers previously associated with risk of cardiovascular disease also predicts incident DM in statin-treated patients with coronary artery disease (CAD). The Treating to New Targets (TNT) study is a randomized trial that compared the efficacy of high (80 mg) versus low (10 mg) dose atorvastatin for the secondary prevention of coronary heart disease events. Fasting plasma levels of standard lipids and of 18 emerging CAD risk biomarkers were obtained after an 8-week run-in period on atorvastatin 10 mg in a random sample of 1,424 TNT patients. After exclusion of patients with DM at baseline (n = 253), 101 patients developed DM during the median follow-up of 4.9 years. Patients with incident DM had lower levels of total and high-molecular weight adiponectin, lipoprotein-associated phospholipase A2 (Lp-PLA2), soluble receptor of advanced glycation end products, and vitamin D compared with patients without incident DM. In contrast, insulin, soluble CD40 ligand, and soluble intercellular adhesion molecule-1 levels were higher in patients with incident DM compared with those without. Plasma levels of C-reactive protein, cystatin C, lipoprotein(a), monocyte chemotactic protein-1, matrix metalloproteinase-9, myeloperoxidase, neopterin, N-terminal fragment of pro-B-type natriuretic peptide, osteopontin, and soluble vascular cell adhesion molecule-1 were comparable in patients with and without incident DM. After multivariate adjustment, total and high-molecular weight adiponectin as well as Lp-PLA2 were negatively associated with incident DM. Results of this study suggest that plasma lipids and some emerging CAD risk biomarkers, such as adiponectin and Lp-PLA2, may be useful for predicting incident DM in statin-treated patients with stable CAD.

    Background: Recent researches have shown that dysfunctional intracellular vesicular trafficking exists in pulmonary arterial hypertension (PAH). However, the expression of proteins involved in intracellular vesicular trafficking in pulmonary vasculature in PAH remains unclear. Objective: To elucidate possible roles of proteins involved in intracellular vesicular trafficking in the development of PAH in rats treated with monocrotaline, changes in the expression of N-ethyl-maleimide-sensitive factor (NSF), α-soluble NSF attachment protein (α-SNAP) and synaptosome-associated membrane protein (SNAP) 23 were examined together with expression of caveolin-1 (cav-1), endogenous nitric oxide synthase (eNOS), type 2 bone morphogenetic receptor (BMPR2) and cellular apoptosis. Methods: The mRNA expression was investigated by real time-PCR and protein expression by immunoblot method in rat lung. Caspase-3 was used as an indicator of cellular apoptosis and examined by immunoblot method. Results: During the development of PAH, mRNA and protein expression of NSF, α-SNAP and SNAP23 all significantly increased before pulmonary arterial pressure started to increase, then all significantly decreased when PAH established. The expression of eNOS and BMPR2 changed similarly, while the mRNA and protein of cav-1 both downregulated after monocrotaline treatment. Caspase-3 was also increased after exposure to monocrotaline. Conclusions: Since the expression of NSF, α-SNAP and SNAP23 changed greatly during the onset of PAH and accompanied with abnormal expression of eNOS, BMPR2 and cav-1 and with enhanced cellular apoptosis, NSF, α-SNAP and SNAP23 appear to be associated with the development of PAH in rats treated with monocrotaline.

    Purpose To evaluate the angiographic findings and embolotherapy in the management of traumatic renal arterial injury Methods This is a retrospective review of 22 patients with renal trauma who underwent arteriography and percutaneous embolization from December 1995 to January 2002. Medical records, imaging studies and procedural reports were reviewed to assess the type of injury, arteriographic findings and immediate embolization results. Long-term clinical outcome was obtained by communication with the trauma physicians and by clinical chart review.Results Arteriography was performed in 125 patients admitted to a State Trauma Center with suspected internal bleeding. Renal arterial injury was documented in 22 and was the result of a motor-vehicle accident (10), auto-pedestrian accident (1), gunshot (4) or stab wounds (6) and a fall (1). Percutaneous renal arterial embolization was undertaken in 22 of 125 (18%) patients to treat extravasation (11), arterial pedicle rupture (5), abnormal arteriovenous (3) or arteriocalyceal (2) communication and pseudoaneurysm (3). One of the pseudoaneurysms and one of the arteriovenous fistulae were found in addition to extravasation. All 22 patients (16 men, 6 women) were hemodynamically stable, or controlled during arteriography and embolotherapy. Selective and/or superselective embolization of the abnormal vessels was performed using coils in 9 patients, microcoils in 9 patients and Gelfoam pledgets in 3 patients. In one patient Gelfoam pledgets mixed with polyvinyl alcohol (PVA) particles were used for embolization. Immediate angiographic evidence of hemostasis was demonstrated in all cases. Two initial technical failures were treated with repeat arteriography and embolization. There was no procedure-related death. There was no non-target embolization. One episode of renal abscess after embolization was treated by nephrectomy and 3 patients underwent elective post-embolization nephrectomy to prevent infection. Follow-up ranged

    Endovascular repair of femoral arterial access complications is nowadays the treatment of choice in a group of patients who cannot tolerate vascular reconstruction and bleeding due to advanced cardiovascular disease. Endovascular procedures can be performed under local anesthesia, are well tolerated by the patient, and are associated with a short hospitalization time. Ninitinol stent technology allows for safe stent and stent-graft extension at the common femoral artery (CFA) level, due to increased resistance to external compression and bending stress. Active pelvic bleeding can be insidious, and prompt placement of a stent-graft at the site of leakage is a lifesaving procedure. Percutaneous thrombin injection under US guidance is the treatment of choice for femoral pseudoaneurysms (PAs); this can theoretically be safer with simultaneous balloon occlusion across the entry site of a PA without a neck or with a short and wide neck. In a few cases with thrombin failure due to a large arterial defect or accompanying arteriovenous fistula (AVF), a stent-graft can be deployed. The vast majority of catheter-induced AVFs can be treated effectively with stent-graft implantation even if they are located very close to the femoral bifurcation. Obstructive dissection flaps localized in the CFA are usually treated with prolonged balloon inflation; however, in more extensive dissections involving iliac arteries, self-expanding stents should be deployed. Iliofemoral thrombosis can be treated effectively with catheter-directed thrombolysis (CDT) followed by prolonged balloon inflation or stent placement. Balloon angioplasty and CDT can occasionally be used to treat stenoses and occlusions complicating the use of percutaneous closure devices.

    Prosthetic graft infections with mediastinitis following aortic surgery are rare, yet represent grave complications yielding high morbidity and mortality. We present the case of a 57-year-old female patient with past history of emergent surgery for iatrogenic Type A dissection treated by supracoronary ascending aortic replacement. Four months after the initial surgery, a sternal fistula had formed and due to severe bleeding emergent reoperation was required. Imaging and pathology on admission revealed an infected pseudoaneurysm at the distal aortic prosthesis and mediastinitis with methicillin-resistant Staphylococcus aureus. Rescue surgery was performed by means of a two-stage approach, with extensive debridement, graft replacement and continuous antiseptic lavage in a first step and an omental wrapping of the new prosthesis in a second stage 24 hours later. During 10 years of follow-up, no recurrent infection occurred. The operative approach and general considerations for management of infected pseudoaneurysms are discussed. PMID:27069945

    Introduction: The purpose of the present study was to analyze complications following antegrade puncture of the common femoral artery (CFA) and the superficial femoral artery (SFA) using vascular closure systems (VCS). Methods: A single-center, retrospective study was performed after obtaining approval from the institutional review board and informed consent from all patients. At our center, the CFA or SFA are used for arterial access. All patients were evaluated clinically on the same day. If there was any suspicion of an access site problem, Duplex ultrasound was performed. Results: Access location was the CFA in 50 patients and the SFA in 130 patients. The sheath size ranged from 4F to 10F. Two patients had to be excluded because of lack of follow-up. Successful hemostasis was achieved in 162 of 178 cases (91 %). The following complications were observed in 16 patients (8.9 %): 4 pseudoaneurysms (2.2 %), 11 hematomas (6.2 %), and 1 vascular occlusion (0.5 %). The two pseudoaneurysms healed spontaneously, in one case an ultrasound-guided thrombin injection was performed, and one aneurysm was compressed manually. No further medical therapy was needed for the hematomas. The one vascular occlusion was treated immediately with angioplasty using a contralateral approach. No significant difference was noted between the CFA and the SFA group with respect to complications (p = 1.000). Conclusions: The use of closure devices for an antegrade approach up to 10F is feasible and safe. No differences in low complication rates were observed between CFA and SFA.

    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.

    We evaluated the clinical outcome of patients with moderate/severe aortic stenosis and significant coronary disease not treated according to guidelines, recommending combined aortic valve replacement (AVR) and coronary artery bypass grafting (CABG). From 2002 to 2010, we assessed death up to 5 years in 650 patients with moderate/severe aortic stenosis and at least one coronary lesion (>50 %): 23 % were treated conservatively (MT), 17 % with percutaneous coronary intervention (PCI), 11 % with AVR, and 49 % with combined CABG and AVR. At a median follow-up of 58 months, overall death decreased over the groups (MT, 68 % vs. PCI, 44 % vs. AVR, 34 % vs. CABG and AVR, 23 %, p < 0.01). Compared to the MT group, Cox regression analysis adjusted for potential confounders showed significantly reduced mortality in the PCI, AVR, and CABG and AVR groups. When combined CABG and AVR is not feasible, PCI or AVR alone still improves significantly long-term survival as compared with MT alone. PMID:26883368

    Background Combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO) is an uncommon retinal vascular disease which causes sudden visual acuity loss and is associated with poor prognosis and the development of severe complications. We report a very rare case of combined CRAO and CRVO in a patient with factor V Leiden (FVL) mutation (only 3 cases published). To our knowledge, this is the first case of combined CRAO and CRVO treated with hyperbaric oxygen therapy (HBOT). Case and Results A 49-year-old woman presented with complaints of sudden loss of vision in her left eye (LE), with best corrected visual acuity (BCVA) of 1/20. A complete ophthalmic evaluation with fundus angiography showed combined CRAO and CRVO. The patient was urgently treated with HBOT (she completed a total of 9 sessions in 7 days), with marked visual acuity and angiographic improvement (BCVA of 10/10). Forty-five days later, she developed a new LE CRVO, and BCVA decreased to 5/10 and later to <1/20 because of significant macular edema. A detailed investigation showed an abnormal resistance to activated protein C, and a genetic study showed homozygosity for FVL mutation. The patient was submitted to 3 monthly injections of 1.25 mg bevacizumab. After 10 months, the patient is in a stable condition with BCVA of 6/10. Conclusions Combined CRAO and CRVO in young adults should be investigated thoroughly for embolic sources, thrombophilic disorders and local ocular conditions. This is the first case of this severe disease that was treated with HBOT, and the visual result was very good. PMID:26955350

    Nonocclusive arterial disease represents less than 5% of posttransplant arterial complications. Nonocclusive arterial complications are classified into (1) nonocclusive diminished flow in the hepatic artery, (2) arteriovenous fistulae, (3) pseudoaneurysms, and (4) arterial rupture. Due to the rarity of these complications, particularly when considering them individually, many of the opinions and managements of these complications are anecdotal. Transcatheter embolization is the main mode of minimal invasive management of these uncommon complications. Other minimal invasive methods have been described such as stent placement or direct percutaneous embolization/thrombosis. The article discusses the presentation, etiology, types, treatment indications, and various modes of minimal invasive therapy used to manage these complications. PMID:18086427

    Contrast extravasation on computed tomography angiography (CTA) is rare but becoming more common, with increasing use of CTA for various cerebral vascular diseases. We report on two cases of spontaneous subarachnoid hemorrhage (SAH) in which the CTA showed an upper basilar trunk saccular lesion suggesting ruptured aneurysm. However, immediate subsequent digital subtraction angiography (DSA) failed to show a vascular lesion. In one case, repeated follow up DSA was also negative. The patient was treated conservatively and discharged without any neurologic deficit. In the other case, the patient showed sudden mental deterioration on the third hospital day and her brain CT showed rebleeding. The immediate follow up DSA showed contrast stagnation in the vicinity of the upper basilar artery, suggestive of pseudoaneurysm. Double stents deployment at the disease segment was performed. Due to the frequent use of CTA, contrast extravasation is an increasingly common observation. Physicians should be aware that basilar artery extravasation can mimic the appearance of an aneurysm.

    Healthcare reform is driving the development of specialty physician practices into larger regional and national physician networks. These networks arise from the federation of > or =2 practices that negotiate with managed-care organizations for contracts. Developing cardiovascular networks and establishing and implementing lipid management quality assurance programs into the network are presented in this article. Goals of the lipid management program include enhancing the identification, diagnosis, education, and comprehensive treatment of patients with cardiovascular disease. Utilizing an integrated, coordinated, multidisciplinary approach to lipid management allows the cardiology network to improve patients' quality of life, reduce long-term costs, and gain a competitive advantage for successful contracting. A network lipid management program involves targeting eligible patients and treating them to a targeted level for low-density lipoprotein (LDL) cholesterol where possible. Among cardiologists, there is a consensus that achieving an LDL cholesterol of < 100 mg/dL for patients with pre-existing cardiovascular disease is desirable. Secondary lipid management program goals include: (1) collecting, storing, and analyzing patient demographics; (2) implementing programs involving lifestyle modification, smoking cessation, weight control; and (3) measuring clinical and economic outcomes. Convergence of several driving forces in managing hypercholesterolemia provides cardiologists with the ability to improve the process. These forces include: market-consolidated delivery systems, established lipid management guidelines, and employer-initiated policies requiring higher quality care within managed-care organizations. Methods to achieve enhanced treatment effectiveness, patient satisfaction, and control costs are discussed.

    Four cases of cervical vertebral artery (VA) dissection are reported. In three patients VA dissection was associated with neck trauma. All patients were young or middle-aged (range 27 to 49 years). In two there was a history of migraine. Pain preceded neurological symptoms from hours to six weeks. Three patients had neurological deficits including elements of the lateral medullary syndrome, and one experienced recurrent transient ischaemic attacks in the vertebrobasilar territory. Angiographic findings included irregular stenosis, occlusion and pseudoaneurysm; in two patients VA abnormalities were bilateral. All patients were treated with anticoagulants and improved. In a review of 28 cases with traumatic dissection and 29 cases with spontaneous dissection of the VA reported in the literature, distinct clinical and angiographic features emerge. Aetiology remains obscure in most cases of spontaneous dissection and management is still controversial. Images PMID:1744639

    Free wall rupture of the left ventricle (LV) is a rare but life-threatening complication of acute myocardial infaction. Very rarely such rupture may be contained by the adhering pericardium creating a pseudoaneurysm. This condition warrants for an emergency surgery. Left ventricular aneurysm is the discrete thinning of the ventricular wall (<5 mm) with akinetic or dyskinetic wall motion causing an out-pouching of the ventricle. Given the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared with a more benign natural history for true aneurysms, accurate diagnosis of these conditions is important. True aneurysm, usually, calls for an elective surgery. Clinically differentiating the two conditions remains a challenge. We report the case of a patient with LV pseudoaneurysm, initially diagnosed as true aneurysm at our institution. We have attempted to review the existing literature and discussed the characteristic findings of each entity. PMID:26750696

    This study was designed to analyze the clinical results in patients suitable for liver transplantation with hepatocellular carcinoma (HCC) who exceeded Milan criteria, which underwent intra-arterial therapies (IAT), to determine predictive factors of successful downstaging. A total of 277 consecutive patients with cirrhosis and HCC were treated by IAT (transarterial oily chemoembolization, transarterial chemoembolization, transarterial embolization) in a single center. Eighty patients exceed the Milan criteria. Patients with infiltrative HCC, hypovascular HCC, and portal vein thrombosis were excluded, with a final study population of 48 patients. Tumor response to IAT was evaluated with CT and/or MRI according to modified RECIST criteria. Successful downstaging was defined as a reduction in the number and size of viable tumors to within the Milan criteria, and serum alpha-fetoprotein (AFP) <100 ng/mL, for at least 6 months. Nineteen patients (39 %) had their tumors successfully downstaged; 29 patients (61 %) did not. Multivariate analysis showed that AFP level <100 ng/mL and 3-year calculated survival probability using the Metroticket calculator were the only independent predictors of successful downstaging (p < 0.023 and p < 0.049 respectively). Biological characteristics of HCC as AFP levels <100 ng/mL and high 3-year calculated survival probability may predict a good response to downstage after IAT.

    Esophageal perforation is a condition associated with high morbidity and mortality rates; it requires early diagnosis and treatment. The most common complication of esophageal rupture is mediastinitis. There are several case reports in the literature of mediastinitis secondary to esophageal perforation and development of aortic pseudoaneurysm as a complication. We report the case of a patient with an 8-day history of esophageal perforation due to foreign body (fishbone) with mediastinitis and aortic pseudoaneurysm. The diagnosis was made using Computed Tomography (CT) with intravenous and oral water-soluble contrast material. An esophagogastroduodenoscopy did not detect the perforation. PMID:26977330

    We report the interesting case of a rare form of presentation of rupture of the ascending aorta with formation of a pseudoaneurysm, diagnosed following the development of a large mass on the surface of the chest over a period of about eight months. Serological tests were positive for syphilis. Echocardiography and computed tomography angiography were essential to confirm the diagnosis and therapeutic management. Cardiovascular syphilis is a rare entity since the discovery of penicillin. Rupture of an aortic aneurysm with formation of a pseudoaneurysm is a potentially fatal complication. The postoperative period was uneventful and the patient was discharged from hospital within days of surgery. PMID:26481180

    Objective: To document clinical experience of treating congenital heart disease combined with large patent ductus arteriosus with pulmonary artery closure in combination with patch technique. Methods: Thirty-six patients (8 males and 28 females) who suffered from congenital heart disease and underwent hybrid surgery in the First Affiliated Hospital of Zhengzhou University from October 2010 to February 2014 were selected for this study. They aged 14 to 39 years and weighed 32.20 to 61.50 kg. Diameter of arterial duct was between 10 mm and 13 mm; 28 cases were tube type, 4 cases were funnel type and four cases were window type. All patients had moderate or severe pulmonary arterial hypertension; besides, there were 28 cases of ventricular septal defect, 16 cases of atrial septal defect, eight cases of aortic insufficiency, four cases of mitral stenosis and insufficiency and four cases of infectious endocarditis. Cardz Pulmonary Bypass (CPB) was established after chest was opened along the middle line. With the help of Transesophageal echocardiography, large patent ductus arteriosus was blocked off through pulmonary artery. Pulmonary artery was cut apart after blocking of heart. Large patent ductus arteriosus on the side of pulmonary artery was strengthened with autologous pericardial patch. Results: Of 36 patients, 32 patients had patent ductus arteriosus closure device and four patients had atrial septal defect closure device. Pulmonary arteries of 36 cases were all successfully closed. Systolic pressure declined after closure ((54.86±19.23) mmHg vs (96.05±23.07) mmHg, p<0.05); average pulmonary arterial pressure also declined after closure ((39.15±14.83) mmHg vs (72.88±15.76) mmHg, p<0.05). The patients were followed up for one to fifty one months (average 11.5 months). Compared to before surgery, left atrial diameter, left ventricular diameter and pulmonary artery diameter all narrowed after surgery. Besides, clinical symptoms were relieved and cardiac

    Purpose: To assess the feasibility and effectiveness of emergency endovascular treatment of acute arterial injuries after orthopedic surgery. Materials and Methods: Fifteen patients (mean age 68.3 years) with acute arterial injuries after orthopedic surgery were observed, in particular, 5 patients with pseudoaneurysm, 9 patients with active bleeding, and 1 patient with arterial dissection. Transarterial embolization (TAE) and positioning of covered and noncovered stents were the treatments performed. Follow-up after stent implantation (mean 36 months) was performed with color Doppler US (CDU) at 1, 3, 6, and 12 months and yearly thereafter. Plain X-ray was performed to evidence dislodgment or fracture of the graft. A minimum of 12 months' follow-up is available after TAE. Results: Immediate technical success was obtained in all cases. No major complications occurred. Overall clinical success rate was 100%. During mean follow-up, stent-graft occlusions did not occurred. No recurrence and/or consequence of TAE was registered during a minimum follow-up of 12 months. Conclusions: Percutaneous treatment is a feasible and safe tool for treating arterial injuries because it can provide fast and definitive resolution of the damage. This low-invasiveness approach can be proposed as first-line treatment in patients with acute injuries after orthopedic surgery.

    We present a case of a 70-year-old man with abdominal aortic aneurysm and coincident pelvic arteriovenous malformation (AVM). Before the operation for the aneurysm, we embolised the pelvic AVM that had multiple feeding arteries and an aneurysmal-dilated draining vein. After decreasing the number of the feeding arteries by coil embolisation, an n-butyl-2-cyanoacrylate/lipiodol mixture (1:1) was injected into the prominent feeding artery and nidus with proximal balloon occlusion of the right internal iliac artery to decrease the flow to the nidus. The mixture (1:4–8) was also added for the finer feeding arteries that became apparent after the initial procedure to embolise the rest of the nidus. A follow-up study showed no contrast enhancement of the nidus and aneurysmal draining vein. PMID:24907213

    Carotid blowout syndrome (CBS) is a high-risk condition associated with significant morbidity and mortality that may result from invasion and destruction of the cervical carotid vasculature from head and neck squamous cell carcinoma. Endovascular approaches offer multiple modalities for treatment to prevent morbidity and death. In this paper we review our experience in addressing CBS and present an up-to-date algorithm of endovascular management. 16 lesions were identified in 8 patients treated with 9 procedures over the past year. Pseudoaneurysm and/or active extravasation were documented in at least one vessel in all 8 cases presenting with acute CBS. There were 13 pseudoaneurysms in external carotid artery (ECA) trunk (5), ECA branches (4), internal carotid artery (ICA) (1) and common carotid artery (CCA) (3). There were 3 additional ICA lesions due to tumor infiltration, resulting in ICA occlusion (2) and long segment stenosis (1). Permanent vessel occlusion was performed in 11 lesions of the ECA trunk (4), ECA branches (4) and ICA (3). Stent-grafts were placed in 5 lesions in the CCA (3), ICA (1) and ECA trunk (1). Technical success and immediate hemostasis were achieved in all patients. There were no procedural deaths or immediate complications. With a median follow-up of 2 months (range, 1-13 months), three patients died: one from recurrent CBS, one from global brain ischemia after a cardiac arrest event unrelated to CBS and one from systemic disease. There was no other recurrence of bleeding or neurological complication. Endovascular techniques offer an armamentarium to effectively address CBS, significantly affecting the care and outcome in this particular oncologic population. These techniques should be offered as early as possible in the context of a multidisciplinary approach. PMID:21990567

    The aim of the current analysis was to characterize the population PK of prasugrel and clopidogrel metabolites, the resulting PD response, and identification of covariates for key PK/PD parameters. Aspirin-treated subjects with coronary artery disease were randomized to double-blind treatment with clopidogrel 600 mg loading dose (LD) followed by daily 75 mg maintenance dose (MD) or prasugrel 60 mg LD and daily 10 mg MD for 28 days. Plasma concentrations of prasugrel active metabolite (Pras-AM) and prasugrel's inactive thiolactone metabolite (Pras-thiolactone) were simultaneously fit to a multicompartmental model; a similar model adequately described clopidogrel's active metabolite (Clop-AM) PK. By linking to the PK model through the active metabolite concentrations, the PK/PD model characterized the irreversible inhibition of platelet aggregation through a sigmoidal Emax model. Although dose, sex, and weight were identified as significant covariates in the prasugrel PK model, only the effect of body weight produced significant changes in Pras-AM exposure. Generally, these factors resulted in only minor changes in Pras-AM exposures such that, overall, the change in the resulting maximal platelet aggregation (MPA) was predicted to be < or =10% points on average. The clopidogrel PK model included dose as a covariate indicating that a significantly less-than-proportional increase in Clop-AM exposure is expected over the dose range of 75-600 mg, thus, the model-predicted PD response is lower than might be anticipated given an 8-fold difference in dose and lower than that typically achieved following prasugrel 60 mg LD. The greater PD response with prasugrel compared with clopidogrel was accounted for by greater conversion of dose to active metabolite. PMID:19023649

    Aspirin and statin therapy are mainstay treatments in patients with coronary artery disease (CAD). The relation between statin therapy, in vivo thromboxane (Tx) generation; a marker of inflammation, and blood thrombogenicity has never been explored. Urinary 11-dehydro (dh) TxB2 was determined in patients with suspected CAD on 325 mg daily aspirin therapy prior to undergoing cardiac catheterisation (n=281). Thrombogenicity was estimated by thrombelastographic measurement of thrombin-induced platelet-fibrin clot strength (TIP-FCS) and lipids/lipoproteins were determined by vertical density gradient ultracentrifugation/ELISA. The influence of statin therapy and dose was analysed by the atorvastatin equivalent dose (5-10 mg, 20-40 mg, or 80 mg daily). Statin therapy (n=186) was associated with a dose-dependent reduction in urinary 11-dh TxB2 (p=0.046) that was independent of LDL and apo B100 levels but was strongly related to TIP-FCS (p=0.006). By multivariate analysis, no statin therapy (n=95) and female gender were independently associated with high urinary 11-dh TxB2 [OR=2.95 (0.1.57-5.50, p=0.0007); OR=2.25 (1.24-4.05, p=0.007)], respectively. In aspirin-treated patients, statin therapy was independently and inversely associated with inflammation in a dose-dependent manner. Elevated 11-dh TxB2 was associated with a prothrombotic state indicated by high TIP-FCS. Our data suggest that measurement of urinary 11-dTxB2 may be a useful method to optimise statin dosing in order to reduce thrombotic risk. PMID:24763965

    Background The expanded usage of drug-eluting stents (DES) in treating patients with multivessel coronary artery disease (CAD) may sometimes be limited in real-world practice due to cost concerns. We compared the clinical outcomes of exclusive and selective DES use in treating patients with multivessel CAD. Methods From November 2004 to December 2011, 110 patients with multivessel CAD who received four or more stents were enrolled into this study, and divided into two groups according to the DES strategy employed: exclusive DES (n = 52), or selective DES (n = 58). In the selective DES group, DES was reserved for complex lesions only, such that the incidence and predictors of clinical events were assessed. Results At a mean follow-up of 41.4 ± 26.5 months, there were no significant differences between the two strategies in terms of baseline characteristics, all-cause mortality (exclusive vs. selective: 1.9% vs. 6.9%, p = 0.21), cardiac death (1.9% vs. 1.7%, p = 0.94) and nonfatal myocardial infarction (3.8% vs. 5.2%, p = 0.74). Despite the presence of more ostial lesions in the exclusive DES group, there was a trend such that major adverse cardiac events (MACE) and target lesion revascularization (TLR) rates were higher in the selective DES group (MACE: 17.3% vs. 31%, p = 0.16; TLR: 11.5% vs. 24.1%, p = 0.08). The higher MACE rate in the selective DES group was mainly driven by a higher target vessel revascularization (TVR) rate (15.4% vs. 29.3%, p = 0.08). In the exclusive DES group, SYNTAX score was an independent predictor of MACE [Haxard ratio (HR): 1.09, 95% confidence internal (CI): 1.02-1.16, p = 0.01] and TVR (HR 1.08, 95% CI 1.01-1.15, p = 0.04). Conclusions Compared to the exclusive DES strategy, the selective DES strategy with reservation of DES for complex lesions is associated with numerically higher, but not statistically significant, rates of MACE and all-cause mortality in this small group of patients with multivessel CAD receiving four or more

    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

    Abstract The aims of this study were to identify arteriographic manifestations of acute renal hemorrhage and to evaluate the efficacy of emergency embolization. Emergency renal artery angiography was performed on 83 patients with acute renal hemorrhage. As soon as bleeding arteries were identified, emergency embolization was performed using gelatin sponge, polyvinyl alcohol particles, and coils. The arteriographic presentation and the effect of the treatment for acute renal hemorrhage were analyzed retrospectively. Contrast extravasation was observed in 41 patients. Renal arteriovenous fistulas were found in 12 of the 41 patients. In all, 8 other patients had a renal pseudoaneurysm, 5 had pseudoaneurysm rupture complicated by a renal arteriovenous fistula, and 1 had pseudoaneurysm rupture complicated by a renal artery-calyceal fistula. Another 16 patients had tumor vasculature seen on arteriography. Before the procedure, 35 patients underwent renal artery computed tomography angiography (CTA). Following emergency embolization, complete hemostasis was achieved in 80 patients, although persistent hematuria was present in 3 renal trauma patients and 1 patient who had undergone percutaneous nephrolithotomy (justifying surgical removal of the ipsilateral kidney in this patient). Two-year follow-up revealed an overall effective rate of 95.18 % (79/83) for emergency embolization. There were no serious complications. Emergency embolization is a safe, effective, minimally invasive treatment for renal hemorrhage. Because of the diversified arteriographic presentation of acute renal hemorrhage, proper selection of the embolic agent is a key to successful hemostasis. Preoperative renal CTA plays an important role in diagnosing and localizing the bleeding artery. PMID:26496273

    Behçet’s disease (BD) is a multisystem autoimmune disorder characterized by recurrent orogenital ulcers, uveitis, and skin lesions. The vascular manifestations include thrombophlebitis, stenosis, occlusion, and pseudoaneurysm. BD infrequently precipitates aortic pseudoaneurysm rupture into the sigmoid mesocolon and lumen of the adjacent colon. Here we report an extremely rare case of spontaneous abdominal aortic pseudoaneurysm rupture via the sigmoid mesocolon into the lumen of the sigmoid colon in a 37-year-old patient with BD.

    Hyperbaric oxygen therapy is the primary treatment for arterial gas embolism, decompression sickness and acute carbon monoxide poisoning. Though there has been a proliferation of hyperbaric centers throughout the United States, a scarcity of centers equipped to treat emergency indications makes transport of patients necessary. To locate and characterize hyperbaric chambers capable of treating emergency cases, a survey of centers throughout the entire United States was conducted. Using Google, Yahoo, HyperbaricLink and the UHMS directory, a database for United States chambers was created. Four researchers called clinicians from the database to administer the survey. All centers were contacted for response until four calls went unreturned or a center declined to be included. The survey assessed chamber readiness to respond to high-acuity patients, including staff availability, use of medical equipment such as ventilators and intravenous infusion devices, and responding yes to treating hyperbaric emergencies within a 12-month period. Only 43 (11.9%, N = 361) centers had equipment, intravenous infusion pumps and ventilators, and staff necessary to treat high-acuity patients. Considering that a primary purpose of hyperbaric oxygen therapy is the treatment of arterial gas embolism and decompression sickness, more hyperbaric centers nationwide should be able to accommodate these emergency cases quickly and safely.

    Endovascular treatment of posttraumatic arteriovenous fistulae (AVFs) in the lower extremities by means of covered stent-grafts is widely accepted, and many cases have been reported in the iliac-femoral region. However, few reports exist on the treatment of infrapopliteal AVFs, with or without a pseudoaneurysm, using this method. The authors present this case report dealing with a patient who had undergone a tibial and peroneal open fracture in his left limb 34 years ago. He developed a leg ulcer as a consequence of AVF between the tibialis posterior artery and vein, which resulted in venous insufficiency, which was treated by the endovascular approach with the placement of a stent-graft. Total healing was achieved over a period of 3 months. Angio-CT was performed, showing stent-graft patency 6 months after the endovascular procedure. PMID:22843636

    We report the case of an 82-year-old woman who developed extensive proximal thigh swelling and persistent anaemia following internal fixation of an extracapsular neck of femur fracture with a dynamic hip screw (DHS). This was revealed to be a pseudoaneurysm of a branch of profunda femoris artery on angiography. Her case was further complicated by a concurrent pulmonary embolism (PE). She underwent endovascular coil embolisation of the pseudoaneurysm. An IVC filter was inserted and the patient was fully anticoagulated once it had been ensured that there was no active bleeding. In this case, we review the potential for anatomical variations in the blood supply to this region and discuss treatment options for a complicated patient. We recommend that a pseudoaneurysm should be part of a differential diagnosis for postoperative patients with anaemia refractory to blood transfusion so as not to miss this rare but potentially serious complication.

    Treatment of bovine pulmonary arterial endothelial cells in culture with the phase II enzyme inducer sulforaphane (5μM, 24h; sulf-treated) increased cell-lysate NAD(P)H:quinone oxidoreductase (NQO1) activity by 5.7 ± 0.6 (mean ± SEM)-fold, but intact-cell NQO1 activity by only 2.8 ± 0.1-fold compared to control cells. To evaluate the hypothesis that the threshold for sulforaphane-induced intact-cell NQO1 activity reflects a limitation in the capacity to supply NADPH at a sufficient rate to drive all the induced NQO1 to its maximum activity, total KOH-extractable pyridine nucleotides were measured in cells treated with duroquinone to stimulate maximal NQO1 activity. NQO1 activation increased NADP(+) in control and sulf-treated cells, with the effect more pronounced in the sulf-treated cells, in which the NADPH was also decreased. Glucose-6-phosphate dehydrogenase (G-6-PDH) inhibition partially blocked NQO1 activity in control and sulf-treated cells, but G-6-PDH overexpression via transient transfection with the human cDNA alleviated neither the restriction on intact sulf-treated cell NQO1 activity nor the impact on the NADPH/NADP(+) ratios. Intracellular ATP levels were not affected by NQO1 activation in control or sulf-treated cells. An increased dependence on extracellular glucose and a rightward shift in the K(m) for extracellular glucose were observed in NQO1-stimulated sulf-treated vs control cells. The data suggest that glucose transport in the sulf-treated cells may be insufficient to support the increased metabolic demand for pentose phosphate pathway-generated NADPH as an explanation for the NQO1 threshold.

    Mycotic aneurysm of the ascending aorta is a rare complication following orthotopic heart transplantation. This article describes a case of mycotic pseudoaneurysm caused by Candida albicans that developed shortly after orthotopic heart transplantation. The pseudoaneurysm compressed the left main coronary artery, which led to the development of congestive heart failure symptoms mimicking sub-acute transplant rejection. The heart failure signs and symptoms resolved completely with resection of the aneurysm. This case reiterates that early diagnosis and complete resection of the aneurysm is associated with good prognosis. PMID:15063413

    Imaging the pregnant patient presents a unique challenge to radiologist due to the risk of radiation to the conceptus (embryo/fetus). A rare case of a successfully recognized and treated pseudoaneurysm (PA) of the abdominal aorta is to be presented. The pseudoaneurysm occurred in the third trimester and had a favorable outcome for the mother and the baby. Emergent abdominal ultrasound (US) is the first modality in diagnostic algorithm for the rupture of aortic aneurysm in a pregnant woman. It provides the most rapid diagnostic information, although intestinal gas and abdominal tenderness may limit its accuracy. To confirm the findings, magnetic resonance angiography (MRA) or CT angiography (CTA) can be used. In our case, the diagnosis was established using a color Doppler ultrasonography of the abdomen and was later confirmed by a low dose CT scan of the abdominal aorta. MRA in such cases have some disadvantages. At many health centers, the monitoring of patients with acute ruptures is more difficult in the MR suite than at the CT scanner. MRA angiographic images are also subject to degradation by multiple artifacts and the visualization of the distal vasculature is suboptimal and inferior to the one done by CTA. Due to fetal movements, a small quantity of fresh blood can be overlooked by MR. MRA is often not available on a 24-hours basis, and the time required for making a diagnosis can preclude the use of MRA in an unstable patient. For this reason, we used a low dose CTA protocol to confirm the diagnosis. Low dose scanning protocols in CT can obtain sufficient diagnostic information while reducing the risk of radiation. A particular focus is put on the outline of new concepts for dose management and optimization. We used new approaches based on tube current modulation. The birth was induced by an urgent Caesarean section followed by a resection of a pseudoaneurysm and a reconstruction of the aorta with an end-to-end vascular prosthesis. PMID:26898082

    The arterial switch operation has been the procedure of first choice for correction of transposition of the great arteries (TGA) for several decades now. However, a large number of adult patients with TGA nowadays were palliated previously by either a Mustard or a Senning procedure. Atrial tachyarrhythmias (ATs) are frequently observed during long-term follow-up of patients with TGA after these atrial switch corrections and are associated with both morbidity and mortality. Because of the complex postoperative anatomy in these patients, ablative therapy for these tachyarrhythmias can be challenging. The goals of this review are to discuss the most prevalent ATs in patients after the Mustard or Senning procedure and to summarize (long-term) outcomes of ablative therapy. In addition, recent developments in ablative therapy for ATs in this patient population are outlined. PMID:27018378

    Internal carotid aneurysms at the base of the skull after blunt trauma are infrequent but their management is difficult, leading many surgeons to only attempt ligation. We report 2 cases presenting with high traumatic aneurysms, following motorcycle accidents. The 2 aneurysms underwent repair by a venous graft. The petrous portion of the carotid artery was approached and controlled by an ENT surgeon. This "infratemporal" approach was used exposing the facial nerve, combined with temporary anterior sub-luxation of the temporomaxillary joint to expose the lower part of the carotid canal which was opened up with a drill in order to control the carotid artery in the petrous canal. Both patients developed facial nerve palsies which improved within 3 months. Postoperative angiography showed patent vein grafts and the patients were doing well, without any symptoms 18 and 24 months later. PMID:1601924

    Tracheo-innominate artery fistula (TIF) is a rare but fatal complication after tracheostomy. Necessary lifesaving measures include proper ventilation, temporary hemostasis, and surgery. Recently, we successfully managed 3 cases of TIF. Ventilation and temporary hemostasis were secured by a long endotracheal tube and overinflated cuff. Division of the innominate artery, restoration of the tracheal fistula with an autologous pericardial patch or direct closure, and aorto-innominate bypass grafting or extra-anatomical bypass grafting with a polytetrafluoroethylene (PTFE) graft were performed through an emergency median sternotomy. All 3 patients recovered with no problems. After TIF occurs, the patient's condition rapidly worsens, and the risk of bacterial contamination in the operative field may increase. Surgical intervention should be performed for patients with tracheal stenosis who are judged to be at high risk for TIF. This preventive surgery includes bypass grafting to divide the innominate artery and partial resection of the anterior bony thorax(upper sternum, medial part of clavicles, and anterior part of upper ribs if necessary). We believe that this procedure will improve tracheal stenosis and minimize the risk of TIF. Thus far, 10 patients have undergone this operation, and their mid-term results are satisfactory.

    We report a case of unruptured fungal internal carotid artery (ICA) aneurysm and review the pertinent literature. A 79-year-old man presented with decreased visual acuity on the right side, and he was diagnosed with retrobulbar optic neuritis. Medical treatment with steroids resulted in Aspergillus meningoencephalitis spreading to the bottom of bilateral frontal lobes, caused by an intracranial extension of sphenoid sinusitis. Magnetic resonance imaging (MRI) performed 26 days after the start of antifungal therapy showed a denovo right ICA aneurysm projecting anteriorly into the sphenoid sinus. As the aneurysm grew rapidly, it was trapped surgically after establishing a high-flow bypass from the external carotid artery to the middle cerebral artery. The patient’s postoperative course was uneventful. Anti-fungal medication was continued until plasma concentrations of beta-D-glucan decreased to within normal limits. Although fungal ICA aneurysm carries a high mortality rate, early detection and prompt treatment by trapping and high-flow bypass can lead to good clinical outcome. PMID:26804189

    The purpose of the study was to investigate the hemodynamic effect of stent struts (wires) on renal arteries in patients with abdominal aortic aneurysms (AAAs) treated with suprarenal stent-grafts. Two sample patients with AAA undergoing multislice CT angiography pre- and postsuprarenal fixation of stent-grafts were selected for inclusion in the study. Eight juxtarenal models focusing on the renal arteries were generated from the multislice CT datasets. Four types of configurations of stent wires crossing the renal artery ostium were simulated in the segmented aorta models: a single wire crossing centrally, a single wire crossing peripherally, a V-shaped wire crossing centrally, and multiple wires crossing peripherally. The blood flow pattern, flow velocity, wall pressure, and wall shear stress at the renal arteries pre- and post-stent-grafting were analyzed and compared using a two-way fluid structure interaction analysis. The stent wire thickness was simulated with a diameter of 0.4, 1.0, and 2.0 mm, and hemodynamic analysis was performed at different cardiac cycles. The interference of stent wires with renal blood flow was mainly determined by the thickness of stent wires and the type of configuration of stent wires crossing the renal ostium. The flow velocity was reduced by 20-30% in most of the situations when the stent wire thickness increased to 1.0 and 2.0 mm. Of the four types of configuration, the single wire crossing centrally resulted in the highest reduction of flow velocity, ranging from 21% to 28.9% among three different wire thicknesses. Wall shear stress was also dependent on the wire thickness, which decreased significantly when the wire thickness reached 1.0 and 2.0 mm. In conclusion, our preliminary study showed that the hemodynamic effect of suprarenal stent wires in patients with AAA treated with suprarenal stent-grafts was determined by the thickness of suprarenal stent wires. Research findings in our study are useful for follow-up of

    Background. To investigate the safety and efficacy of superselective transcatheter arterial embolization (TAE) with n-butyl cyanoacrylate (NBCA) in treating lower gastrointestinal bleeding caused by angiodysplasia. Methods. A retrospective study was performed to evaluate the clinical data of the patients with lower gastrointestinal bleeding caused by angiodysplasia. The patients were treated with superselective TAE with NBCA between September 2013 and March 2015. Angiography was performed after the embolization. The clinical signs including melena, anemia, and blood transfusion treatment were evaluated. The complications including abdominal pain and intestinal ischemia necrosis were recorded. The patients were followed up to evaluate the efficacy in the long run. Results. Seven cases (2 males, 5 females; age of 69.55 ± 2.25) were evaluated in the study. The embolization was successfully performed in all cases. About 0.2–0.8 mL (mean 0.48 ± 0.19 mL) NCBA was used. Immediate angiography after the embolization operation showed that the abnormal symptoms disappeared. The patients were followed up for a range of 2–19 months and six patients did not reoccur. No serious complications, such as femoral artery puncture point anomaly, vascular injury, and intestinal necrosis perforation were observed. Conclusion. For the patients with refractory and repeated lower gastrointestinal hemorrhage due to angiodysplasia, superselective TAE with NBCA seem to be a safe and effective alternative therapy when endoscopy examination and treatment do not work.

    OBJECTIVES: Behcet’s disease is a form of systematic vasculitis that affects vessels of various sizes. Aortic pseudoaneurysm is one of the most important causes of death among patients with Behcet’s disease due to its high risk of rupture and associated mortality. Our study aimed to investigate the outcomes of Behcet’s disease patients with aortic pseudoaneurysms undergoing open surgery and endovascular aortic repair. METHODS: From January 2003 to September 2014, ten consecutive patients undergoing surgery for aortic pseudoaneurysm met the diagnostic criteria for Behcet’s disease. Endovascular repair was the preferred modality and open surgery was performed as an alternative. Systemic immunosuppressive medication was administered after Behcet’s disease was definitively diagnosed. RESULTS: Eight patients initially underwent endovascular repair and two patients initially underwent open surgery. The overall success rate was 90% and the only failed case involved the use of the chimney technique to reach a suprarenal location. The median follow-up duration was 23 months. There were 7 recurrences in 5 patients. The median interval between operation and recurrence was 13 months. No significant risk factors for recurrence were identified, but a difference in recurrence between treatment and non-treatment with preoperative immunosuppressive medication preoperatively was notable. Four aneurysm-related deaths occurred within the follow-up period. The overall 1-year, 3-year and 5-year survival rates were 80%, 64% and 48%, respectively. CONCLUSIONS: Both open surgery and endovascular repair are safe and effective for treating aortic pseudoaneurysm in Behcet’s disease patients. The results from our retrospective study indicated that immunosuppressive medication was essential to defer the occurrence and development of recurrent aneurysms. PMID:27438562

    A large aneurysm of the left renal artery was found incidentally during abdominal ultrasound in a 39-year-old woman with no medical or family history of cardiovascular disease. Vascular pathology with a dysplastic appearance was confirmed by magnetic resonance angiography and the patient was offered transcatheter embolization. Since the position and size of the neck of the aneurysm could not be determined at angiography, detachable platinum coils were used for occlusion. The procedure was performed without complications. During a 4-year follow-up no alterations of renal function, recanalization of the aneurysm, or perfusion defects in the rest of the left renal circulation were noted.

    Traumatic nonanastomtic disruption of an axillofemoral bypass graft (AFBG) is a relatively rare entity. However, we are reporting on an 82-year-old female who presented with a pulsating mass on her left side, which was noticed about 2 weeks after she fell on her side. The patient had undergone an ABFG about 15 years earlier for limb revascularization, and she had an occluded aortobifemoral bypass graft. A diagnosis of localized rupture with pseudoaneurysm (PSA) was confirmed with arterial duplex ultrasound and computed tomograph (CT) angiogram scans. A 7-cm PSA with partial disruption of the polytetrafluoroethylene (PTFE) graft at the level of the fifth thoracic vertebrae was noted. An initial work-up to eliminate the possibility of sepsis and localized mycotic seeding was negative. The patient was taken to the hybrid angiogram room, and a percutaneous cut down of the AFBG was performed with local dissection below the site of rupture. A limited angiogram showed a focal PSA of the AFBG. An intravascular ultrasound (IVUS) was performed to calibrate the diameter of the AFBG, and a covered stent was deployed across the area of the disrupted graft. A completion angiogram showed complete exclusion of the PSA with good runoff throughout the graft. The authors will review the management of the traumatic PSA with an endovascular approach.

    It has been estimated that up to half of circulating factor XIIIa (FXIIIa) is stored in platelets. The release of FXIIIa from platelets upon stimulation with adenosine diphosphate (ADP) in patients with coronary artery disease treated with dual antiplatelet therapy has not been previously examined. Samples from 96 patients with established coronary artery disease treated with aspirin and clopidogrel were examined. Platelet aggregation was performed by light transmittance aggregometry in platelet-rich plasma (PRP), with platelet-poor plasma (PPP) as reference, and ADP 5 µM as agonist. Kaolin-activated thrombelastography (TEG) was performed in citrate PPP. PRP after aggregation was centrifuged and plasma supernatant (PSN) collected. FXIIIa was measured in PPP and PSN. Platelet aggregation after stimulation with ADP 5 µM resulted in 24% additional FXIIIa release in PSN as compared to PPP (99.3 ± 27 vs. 80.3 ± 24%, p < 0.0001). FXIIIa concentration in PSN correlated with maximal plasma clot strength (TEG-G) (r = 0.48, p < 0.0001), but not in PPP (r = 0.15, p = 0.14). Increasing quartiles of platelet-derived FXIIIa were associated with incrementally higher TEG-G (p = 0.012). FXIIIa release was similar between clopidogrel responders and non-responders (p = 0.18). In summary, platelets treated with aspirin and clopidogrel release a significant amount of FXIIIa upon aggregation by ADP. Platelet-derived FXIIIa may contribute to differences in plasma TEG-G, and thus, in part, provide a mechanistic explanation for high clot strength observed as a consequence of platelet activation. Variability in clopidogrel response does not significantly influence FXIIIa release from platelets. PMID:24833046

    An adolescent male sustained a severe penetrating injury to the external iliac artery. Emergency surgical revascularization was with a reversed long saphenous vein interposition graft. The primary graft and the subsequent revision graft both became aneurysmal. The second graft aneurysm was successfully excluded by endovascular stent-grafts with medium-term primary patency. A venous graft was used initially rather than a synthetic graft to reduce the risk of infection and the potential problems from future growth. Aneurysmal dilatation of venous grafts in children and adolescents is a rare but recognized complication. To the best of our knowledge, exclusion of these aneurysms with stent-grafts has not been previously reported in the adolescent population.

    Esophageal perforation caused by accidental swallowing of fish bones can lead to rare complications, such as aortoesophageal fistula accompanied by aortic pseudoaneurysm, which can be fatal if not properly handled. We report two rare cases of aortoesophageal fistula and aortic pseudoaneurysm caused by esophagus perforation after accidental swallow of fish bone; the patients also had purulent mediastinitis and esophagitis. The treatment of aortic pseudoaneurysm was successful in both cases, with one patient undergoing surgical resection and aortic neoplasty and the other patient undergoing endovascular stent graft placement. Long-term antibiotic treatment was administered to both patients after surgery. There were no postsurgical complications, and the patients recovered without incident.

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

    PurposeThis study was designed to assess the efficacy and safety of the ExoSeal vascular closure device (VCD) to achieve hemostasis in antegrade access of the superficial femoral artery (SFA).MethodsWe retrospectively reviewed the outcome of ExoSeal VCD used for hemostasis in 110 accesses to the SFA in 93 patients between July 2011 and July 2013. All patients had patent proximal SFA based on computer tomography angiography or ultrasound duplex. Arterial calcifications at puncture site were graded using fluoroscopy. The SFA was accessed in an antegrade fashion with ultrasound or fluoroscopic guidance. In all patients, 5–7F vascular sheaths were used. The ExoSeal VCD was applied to achieve hemostasis at the end of the procedure. All patients were clinically examined and had ultrasound duplex exam for any puncture site complications during the 24 h postprocedure.ResultsIn all procedures, the ExoSeal was applied successfully. We did not encounter any device-related technical failure. There were four major complications in four patients (3.6 %): three pseudoaneurysms, which were treated with direct thrombin injection, and one hematoma, which necessitated transfusion of two blood units. All patients with complications were treated with anticoagulation preprocedure or received thrombolytic therapy.ConclusionsThe ExoSeal VCD can be safely used for antegrade puncture of the SFA, with a high procedural success rate (100 %) and a low rate of access site complications (3.6 %)

    An 81-year-old male with previous open abdominal aortic aneurysm repair presented with asymptomatic large pseudoaneurysms at both ends of an open surgical tube graft. Endovascular aneurysm sealing (EVAS) in combination with the iliac limbs of a standard endovascular aneurysm repair (EVAR) successfully excluded both pseudoaneurysms from circulation. We describe the combination of elements of EVAS and EVAR and have termed this endovascular aneurysm repair and sealing (EVARS). EVARS has the advantage of harnessing the benefits of endobag sealing in aortic necks unsuitable for standard EVAR whilst providing the security of accurate stent placement within short common iliac arteries. In conclusion, EVAS may be combined with standard endovascular iliac limbs and is a possible treatment option for pseudoaneurysm following open aneurysm repair. PMID:26493819

    Background— The safety and effectiveness of non–vitamin K antagonist (VKA) oral anticoagulants, dabigatran or rivaroxaban, were compared with VKA in anticoagulant-naive patients with nonvalvular atrial fibrillation during the early phase of anticoagulant therapy. Methods and Results— With the use of the French medico-administrative databases (SNIIRAM and PMSI), this nationwide cohort study included patients with nonvalvular atrial fibrillation who initiated dabigatran or rivaroxaban between July and November 2012 or VKA between July and November 2011. Patients presenting a contraindication to oral anticoagulants were excluded. Dabigatran and rivaroxaban new users were matched to VKA new users by the use of 1:2 matching on the propensity score. Patients were followed for up to 90 days until outcome, death, loss to follow-up, or December 31 of the inclusion year. Hazard ratios of hospitalizations for bleeding and arterial thromboembolic events were estimated in an intent-to-treat analysis using Cox regression models. The population was composed of 19 713 VKA, 8443 dabigatran, and 4651 rivaroxaban new users. All dabigatran- and rivaroxaban-treated patients were matched to 16 014 and 9301 VKA-treated patients, respectively. Among dabigatran-, rivaroxaban-, and their VKA-matched–treated patients, 55 and 122 and 31 and 68 bleeding events and 33 and 58 and 12 and 28 arterial thromboembolic events were observed during follow-up, respectively. After matching, no statistically significant difference in bleeding (hazard ratio, 0.88; 95% confidence interval, 0.64–1.21) or thromboembolic (hazard ratio, 1.10; 95% confidence interval, 0.72–1.69) risk was observed between dabigatran and VKA new users. Bleeding (hazard ratio, 0.98; 95% confidence interval, 0.64–1.51) and ischemic (hazard ratio, 0.93; 95% confidence interval, 0.47–1.85) risks were comparable between rivaroxaban and VKA new users. Conclusions— In this propensity-matched cohort study, our findings

    Background Atrial fibrillation (AF) is one of the most common complications after cardiac surgery. Several therapeutic and preventive strategies have been introduced for postoperative AF, but the treatment and prophylaxis of AF remain controversial. We aimed to compare the efficacy of intravenous amiodarone and oral propafenone in the treatment of AF after coronary artery bypass grafting (CABG). Methods This was a randomized controlled trial performed in two hospitals in Shiraz, Iran from 2009 to 2012. We included all patients who underwent elective CABG and developed AF postoperatively. The patients were randomly assigned to receive propafenone or amiodarone. The duration of AF, the success rate of the treatment, the need for cardioversion, the frequency of repeated AF, and the need for repeating the treatment were compared. Results The duration of the first (p=0.361), second (p=0.832), and third (p=0.298) episodes of AF, the need for cardioversion (p=0.998), and the need to repeat the first and second doses of drugs (p=0.557, 0.699) were comparable between the study groups. Repeated AF was observed in 17 patients (30.9%) in the propafenone group and 23 patients (34.3%) in the amiodarone group (p=0.704). Conclusion Oral propafenone and intravenous amiodarone are equally effective in the treatment and conversion of recent-onset AF after CABG. PMID:27298795

    Background. Endosaccular coiling, vessel occlusion, stenting, stent-assisted coiling, and flow diversion are all endovascular treatment options for pseudoaneurysms (PAs) of the head and neck. We explore different clinical situations in which these were selected for PA management at a single institution. Methods. Over a period of ten years, 33 patients presented to our hospital with PAs of the head and neck. Their outcomes and procedural complications are discussed. Results. We observed a complication rate of 18.2% (6 of 33), consisting predominantly of infarcts following vessel occlusion. As measured by the modified Rankin Scale, 25 (75.8%) patients had achieved favorable outcomes on discharge. A single patient who was treated with stent-assisted coiling expired following procedural complications. Conclusions. In our series, most patients with traumatic/iatrogenic PAs were successfully treated with parent vessel sacrifice. When parent vessel occlusion is not an option, stenting with or without coiling, or flow diversion, may also be safe and effective alternatives. PMID:25401139

    Two cases of left ventricular pseudoaneurysm following myocardial infarction are presented. In the first patient a two-dimensional echocardiography study revealed a small posterior echo-free space that appeared to communicate with the left ventricle through a small defect in the left ventricular posterior wall. Conventional Doppler echocardiography and colour flow imaging demonstrated flow between the left ventricle and the paraventricular chamber. In the other patient, the same study detected an enormous false aneurysm. We found a large extramyocardial echo-free space within the pericardial cavity. The site of this space was posterolateral and communicating with the left ventricular cavity. Cardiac catheterization and surgery confirmed the diagnosis. A postoperative echocardiographic study demonstrated a persistent but smaller saccular echo-free space and a residual shunt through one site of repair in the first patient; in the other, after surgical treatment there was no residual flow, but a left ventricular dysfunction was detected. Two dimensional and color Doppler echocardiography is the best technique among the noninvasive methods, for detecting and following up left ventricular pseudoaneurysms. PMID:8325466

    We present a 28-year-old man with a large symptomatic arteriovenous fistula (AVF) treated with embolization using the Amplatzer vascular plug (AVP). Although embolization may be considered the first-line therapy in the treatment of AVFs, there is an inherent high risk of migration of the embolic agents into the venous and pulmonary circulations. This case is illustrative of the ease and safety of using this device in high-flow renal AVFs.

    Pseudoaneurysm formation often complicates transfemoral interventional procedures. Nonsurgical treatment consists of femoral compression and thrombin injection under ultrasound guidance. We report a 74-year-old man who was diagnosed with a pseudoaneurysm, following coronary angiography. Duplex ultrasound revealed deep vein thrombosis of the ipsilateral common femoral vein. Ultrasound-guided thrombin injection was unsuccessfully performed, and the patient subsequently underwent surgical exploration for repair of the pseudoaneurysm and release of the venous compression. The increased local inflammation, because of the thrombosis, added in surgical difficulties. We conclude that early surgical intervention should be considered as a primary strategy in patients with femoral pseudoaneurysms and deep vein thrombosis secondary to femoral compression.

    Objective To evaluate the rate of and potential risk factors for bloodstream infections (BSIs) using data from the REVEAL (Registry to Evaluate Early and Long-term Pulmonary Arterial Hypertension [PAH] Disease Management) REGISTRY®, which provides current information about patients with PAH. Patients and Methods Patients were enrolled from March 30, 2006, through December 8, 2009, and data on reported BSIs were collected through the third quarter of 2010. Bloodstream infection rates were calculated per 1000 patient-days of risk. Results Of 3518 patients enrolled, 1146 patients received intravenous (IV) prostanoid therapy for more than 1 day (no BSI, n=1023; ≥1 BSI, n=123; total BSI episodes, n=166). Bloodstream infections rates were significantly increased in patients receiving IV treprostinil vs IV epoprostenol (0.36 vs 0.12 per 1000 treatment days; P<.001), primarily due to gram-negative organisms (0.20 vs 0.03 per 1000 treatment days; P<.001). Multivariate analysis adjusting for age, causes of PAH, and year of BSI found that treatment with IV treprostinil was associated with a 3.08-fold increase (95% confidence interval, 2.05-4.62; P<.001) in BSIs of any type and a 6.86-fold increase (95% confidence interval, 3.60-13.07; P<.001) in gram-negative BSIs compared with treatment with IV epoprostenol. Conclusion Compared with IV epoprostenol therapy, treatment with IV treprostinil is associated with a significantly higher rate of gram-negative BSIs; observed differences in BSI rate did not seem to be due to any other analyzed factors.

    PURPOSE We aimed to investigate the safety and effectiveness of intracranial stenting in a population with severe (≥70%) symptomatic intracranial internal carotid artery (ICA) atherosclerotic stenosis. METHODS Fifty-eight patients with severe intracranial ICA atherosclerotic stenosis were prospectively enrolled. The baseline data, cerebral angiography, success rate, perioperative complications, clinical and imaging follow-up were prospectively analyzed. RESULTS All patients had successful intracranial stenting (100%), and the mean degree of stenosis was improved from 84.3%±7.5% to 23.5%±5.1% after the stent procedure. During the 30-day perioperative period, only one patient (1.7%) had ischemic stroke. Seven patients (12.1%) had headache and dysphoria. Thirty-six patients (62.1%) had clinical follow-up for 6–68 months after stenting. Five female patients (13.9%) had ipsilateral stroke including one death, but no disabling stroke, while three other patients (8.3%) had ipsilateral temporary ischemic attack (TIA). The recurrent stroke rate was higher in patients presenting with stroke (4/17, 23.5%) than in patients presenting with TIA (1/19, 5.3%), with no statistical significance (P = 0.33). Thirteen patients (22.4%) had imaging follow-up of 5–12 months following stenting, five of whom (38.5%) had in-stent restenosis. CONCLUSION Intracranial stenting for patients with intracranial ICA atherosclerotic stenosis has a low perioperative stroke rate and decent outcome on long-term follow-up, despite a relatively high in-stent restenosis rate.

    The aim of the present study was to investigate the association between serum vascular endothelial growth factor (VEGF) and insulin-like growth factor 1 (IGF-1) levels and the prognosis of patients with uterine fibroids following uterine artery embolization (UAE) treatment. A total of 70 patients with uterine fibroids and 20 healthy controls were enrolled in this study between 2012 and 2014. The serum levels of IGF-1 and VEGF were measured using ELISA. Multiple-factor analysis was performed to assess the association between serum levels of IGF-1/VEGF and certain clinical characteristics, including size, location, number of uterine fibroids and adenomyosis. Progression-free survival curves were analyzed using the Kaplan-Meier method. The serum levels of IGF-1 and VEGF in patients with uterine fibroids prior to UAE treatment were significantly higher than those in controls (P<0.05). At 1 week after UAE treatment, the serum levels of IGF-1 and VEGF were significantly lower compared with those prior to UAE treatment. The serum levels of IGF-1 and VEGF at 1 or 3 months after UAE treatment were significantly higher than those at 1 week after UAE treatment. The serum levels of IGF-1 and VEGF were significantly correlated with the clinical characteristics of uterine fibroids (P<0.05). Lower levels of IGF-1 and VEGF in the serum following UAE treatment were associated with an enhanced progression-free survival of patients. In conclusion, the levels of IGF-1 and VEGF in the serum following UAE treatment can be used as indicators of prognosis in patients with uterine fibroids. PMID:26893660

    Blunt gallbladder injury is rare, and bleeding from the cystic artery due to blunt trauma is even rarer. We report herein a case of extraluminal bleeding of the gallbladder in a patient following blunt abdominal trauma. Contrast-enhanced computed tomography revealed pericholecystic fluid and extravasation of contrast material in the subcapsular liver space adjacent to the gallbladder. Abdominal digital subtraction angiography revealed pseudoaneurysm originating from a branch of the cystic artery. Successful treatment was achieved using selective transcatheter embolization, and cholecystectomy was not required. PMID:20182852

    Blunt traumatic infrarenal aortic injuries are unusual, and the formation of a delayed pseudoaneurysm of the aorta is even more rare. In this report, a young woman developed a small intimal flap of the infrarenal aorta after a motor vehicle accident which progressed into a 3 cm pseudoaneurysm after 3 months. Operative repair was successful and the patient recovered. This case illustrates the importance of repeat imaging of small blunt aortic injuries since progression can occur. PMID:27252519

    Purpose: To investigate the percutaneous endovascular management of visceral aneurysms (VA) and visceral pseudoaneurysms (VPA) treated in three European interventional radiology departments. Methods: Patient archives from the department's databases were examined and retrospectively analyzed. Patients diagnosed between 2000 and 2010 with VA and/or VPA, confirmed by computed tomography angiography, magnetic resonance angiography, or digital subtraction angiography and treated exclusively with percutaneous endovascular methods, were included in the study. The study's primary end points were procedural technical success, target lesion reintervention rate, and periprocedural mortality rate. Secondary end points included major and minor complications rates. Results: The medical records of 54 patients (41 male, mean age 55 {+-} 18.1 years) with 58 VAs or VPAs and treated with various percutaneous endovascular therapeutic modalities were analyzed. In total, 21 VAs (mean diameter 49.4 {+-} 21 mm, range 20-100 mm) and 37 VPAs (mean diameter 25.1 {+-} 14.6 mm, range 8-60 mm) were treated. Procedural technical success was achieved in 100% of the cases, while target lesion reintervention rate was 6.1% (2 of 33) and 14.2% (3 of 21) in the VPA and VA groups, respectively. Mean clinical follow-up period was 19.1 {+-} 21.4 months. Overall periprocedural mortality rate was 3% (1 of 33) in the VPA group and 0% (0 of 21) in the VA group. Conclusion: Percutaneous endovascular treatment of VAs and VPAs is safe and effective with low morbidity and mortality. There is a small but significant reintervention rate, particularly for true aneurysms; dedicated follow-up imaging is recommended. Successful aneurysm exclusion was achieved in all cases with a second procedure.

    Mycobacterium kansasii is a photochromogenic, slow-growing mycobacterium species that can cause pulmonary infection in patients with predisposing lung diseases, as well as extrapulmonary or disseminated disease in immunosuppressed patients. We describe a patient with a myelodysplastic syndrome, disseminated M kansasii infection, and ruptured aortic aneurysm. He had a recent diagnosis of mycobacterium cavitary lung lesions and was transferred to our facility for possible surgical intervention of an aortic aneurysm. Few hours after admission, the patient suddenly collapsed and died despite resuscitation efforts. A complete autopsy was performed and showed ruptured ascending aortic pseudoaneurysm with hemopericardium, disseminated necrotizing and nonnecrotizing granulomas with acid-fast bacilli in the aortic wall, lungs, heart, liver, spleen, and kidneys. Further genetic studies were consistent with monocytopenia and mycobacterial infection syndrome. PMID:25537975

    Failing to reach blood pressure (BP) goals is one of the main problems in hypertension management. Especially in high-risk patients, intensive monitoring including frequently office visits or new techniques to monitor home BP is required. A total of 60 patients with uncontrolled hypertension were included and randomized into a group with telemetric BP monitoring (TBPM) (n=30) and a control group receiving standard care (n=30). During the 3-month study period, patients received in addition to their antihypertensive pre-treatment up to 2 × 300 mg irbesartan to achieve the required target BP. All patients were instructed to measure their BP once daily in the morning. In the TBPM group automatic alerts were generated by the central database server using pre-defined algorithms and patients were subsequently contacted by the physician. At baseline mean 24-h ambulant BP monitoring (ABPM) was 143.3±11.1/82.6±9.9 mm Hg in the TBPM group and 141.4±12.6/82.1±6.5 mm Hg in the standard care group. During treatment mean systolic BP showed a more intensive decrease in the TBPM vs control group (-17.0±11.1 mm Hg vs -9.8±13.7 mm Hg; P=0.032). Patients in the TBPM group had a more pronounced night dipping and a higher reduction of mean pulse pressure than controls (-8.1±5.9 mm Hg vs -2.8±7.4 mm Hg, P=0.004). After 3 months, TBPM-treated patients were given a higher mean daily dose of irbesartan (375±187 mg vs 222±147 mg in controls; P=<0.001). We demonstrated that with TBPM a more effective and faster titration of the antihypertensive agent is possible. The alarm criteria chosen were useful to improve BP control. PMID:21228822

    Sildenafil and bosentan are increasingly used for the treatment of pulmonary arterial hypertension (PAH) in HIV-infected patients. However, concerns exist about pharmacokinetic interactions among sildenafil, bosentan and antiretroviral drugs, including protease inhibitors (PI). We describe here the case of an HIV-infected patient with PAH, who was co-administered bosentan 125 mg twice daily and sildenafil 40 mg three times per day, together with a ritonavir-boosted PI-based antiretroviral therapy; plasma levels of bosentan, sildenafil, N-desmethylsildenafil, and PI were measured. The patient had a sildenafil Cthrough and Cmax of 276.94 ng/mL and 1733.19 ng/mL, respectively. The Cthrough and the Cmax of bosentan were 1546.53 ng/mL and 3365.99 ng/mL, respectively. The patient was able to tolerate as high sildenafil blood concentrations as 10 times those usually requested and did not report any significant adverse reaction to sildenafil during the follow-up period. Therapeutic drug monitoring should be considered during sildenafil therapy in patients concomitantly treated with ritonavir-boosted PI. PMID:25874072

    For over six decades intra-arterial (IA) drugs have been sporadically used for the treatment of lethal brain diseases. In recent years considerable advance has been made in the IA treatment of retinoblastomas, liver and locally invasive breast cancers, but relatively little progress has been made in the treatment of brain cancers. High resting blood flow and the presence of the blood-brain barrier (BBB), makes IA delivery to the brain tissue far more challenging, compared to other organs. The lack of advance in the field is also partly due to the inability to understand the complex pharmacokinetics of IA drugs as it is difficult to track drug concentrations in sub-second time frame by conventional chemical methods. The advances in optical imaging now provide unprecedented insights into the pharmacokinetics of IA drug and optical tracer delivery. Novel delivery methods, improved IA drug formulations, and optical pharmacokinetics, present us with untested paradigms in pharmacology that could lead to new therapeutic interventions for brain cancers and stroke. The object of this review is to bring into focus the current practice, problems, and the potential of IA drug delivery for treating brain diseases. A concerted effort is needed at basic sciences (pharmacology and drug imaging), and translational (drug delivery techniques and protocol development) levels by the interventional neuroradiology community to advance the field.

    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

    Joint hemorrhages are very common in patients with severe hemophilia. Inhibitors in patients with hemophilia are allo-antibodies that neutralize the activity of the clotting factor. After total knee replacement, rare intra-articular bleeding complications might occur that do not respond to clotting factor replacement. We report a 40-year-old male with severe hemophilia A and high responding inhibitors presenting with recurrent knee joint hemorrhage after bilateral knee prosthetic surgery despite adequate clotting factor treatment. There were two episodes of marked postoperative hemarthrosis requiring extensive use of subsititution therapy. Eleven days postoperatively, there was further hemorrhage into the right knee. Digital subtraction angiography diagnosed a complicating pseudoaneurysm of the inferior lateral geniculate artery and embolization was successfully performed. Because clotting factor replacement therapy has proved to be excessively expensive and prolonged, especially in patients with inhibitors, we recommend the use of cost-effective early angiographic embolization.

    Authors report a case of a 31 years old patient who eliminate a urinary stone which contains a platinium coil. Five years ago, this patient had a percutaneous nephrolithotomy. A persistent hematuria was successfully managed with angioembolization of a lower polar artery branch. One of the coils was deployed too distally. It was not efficient, it rolled itself up in the pseudoaneurysm cavity. Different physio pathological hypothesis are developed to explain this expulsion. PMID:17634005

    Postoperative celiac artery stenosis (CAS) rarely occurs in the absence of vascular injury or pseudoaneurysm after pancreatoduodenectomy (PD). Because of its low incidence, the optimal treatment for non-traumatic postoperative CAS is unknown. Here, we show a case of CAS possibly due to exacerbated median arcuate ligament compression after PD. The purpose of this report is to describe this rare complication and its successful endovascular treatment with review of literatures. PMID:27375809

    Purpose. To assess the effectiveness of endovascular treatment of anastomotic pseudoaneurysms (APAs) following aorto-iliac surgical reconstruction. Materials. We retrospectively evaluated 21 men who, between July 2000 and March 2006, were observed with 30 APAs, 13 to the proximal anastomosis and 17 to the distal anastomosis. The patients had had previous aorto-iliac reconstructive surgery with a bypass due to aneurysm (15/21) or obstructive disease (6/21). The following devices were used: 12 bifurcated endoprostheses, 2 aorto-monoiliac, 4 aortic extenders, 1 stent-graft leg, and 2 covered stents. Follow-up was performed with CT angiography at 1, 3, and 6 months after the procedure and yearly thereafter. Results. Immediate technical success was 100%. No periprocedural complications occurred. Four patients died during follow-up from causes not related to APA, and 1 (treated for prosthetic-enteric fistula) from sepsis 3 months after the procedure. During a mean follow-up of 19.7 months (range 1-72 months), 2 of 21 occlusions of stent-graft legs occurred 3 and 24 months after the procedure (treated with thrombolysis and percutaneous transluminal angioplasty and femorofemoral bypass, respectively) and 1 type I endoleak. Primary clinical success rate was 81% and secondary clinical success was 91%. Conclusion. Endovascular treatment is a valid alternative to open surgery and can be proposed as the treatment of choice for APAs, especially in patients who are a high surgical risk. Further studies with larger series and longer follow-up are necessary to confirm the long-term effectiveness of this approach.

    Left ventricular outflow tract (LVOT) pseudoaneurysm is a rare but potentially lethal complication, mainly after aortic root endocarditis or surgery. Usually it originates from a dehiscence in the mitral-aortic intervalvular fibrosa and it arises posteriorly to the aortic root. Due to these anatomical features, its imaging assessment is challenging and surgical repair requires complex procedures. An unusual case of LVOT pseudoaneurysm is described. It was detected by transthoracic ecocardiography 7 months after aortic root replacement for acute endocarditis. Multidetector computed tomography (MDCT) confirmed the presence of a pouch located between the aortic root and the right atrium. Computed tomography also detected the origin of the pseudoaneurysm from the muscular interventricular septum of the LVOT, rather below the aortic valve plane. It was repaired with an extracardiac surgical approach, sparing the aortic root bioprosthesis previously implanted. The high-resolution three-dimensional details provided by the preoperative MDCT allowed us to plan a simple and effective surgical strategy.

    Left ventricular aneurysm is one of the most troublesome complications of myocardial infarction. This complication results from LV wall rupture and presents as a cavity contained by pericardium and fragments of the ruptured wall. The risk of pseudoaneurysm rupture is very high and this makes the prognosis for the disease extremely unfavorable. A surgical correction, involving a patch repair of the LV wall, seems to be the only treatment modality. Echocardiography makes it possible to diagnose pseudoaneurysm of the left ventricle in most cases, while intraoperative transesophageal echocardiography is required for the in-process monitoring of intracardiac hemodynamics and assessment of intervention efficiency.

    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

    A 9-day-old boy had pulmonary artery banding and extended end-to-end aortic arch anastomosis for ventricular septal defect (VSD) and type A interrupted aortic arch. Severe dyspnea gradually developed. At 3 months of age, intracardiac repair of VSD was performed. Weaning from the ventilator was difficult. Endoscopic examination and chest CT revealed stenosis of the right and left main bronchi and compression of tracheal bifurcation and the right and left main bronchi by the ascending aorta and pulmonary artery. Suspension of the ascending aorta and pulmonary artery was performed 15 days after VSD closure. Nine days after this procedure, the patient was weaned from respirator. Postoperative course was uneventful. Bronchial stenosis may be caused from extended end-to-end aortic arch anastomosis. PMID:11211771

    Abstract Local complications at the radial access site are not frequent, hence its large diffusion as the preferred access route for endovascular procedures. However, in a time of fast widespreading, better comprehension of all potential complications becomes critical to facilitate their early recognition and the most appropriate treatment. In this case report, we present for the first time a case of sudden massive bleeding at the left wrist, due to spontaneous gross rupture of the left radial artery bleeding 15 days after an endovascular procedure through a left radial arterial access. The patient had been readmitted to the hospital after evidence of local infection at the left wrist with loss of substance. The radial artery was patent with no evidence of pseudoaneurysm. After sudden radial artery rupture, with massive bleeding and suspicion that the local infection could have reached the arterial wall, surgical hemostasis with artery ligation was obtained. Healing of the large wound was then efficiently speeded up using a negative pressure wound therapy. This is the first case of macroscopic radial artery rupture associated with local wrist infection after arterial catheterization. After prompt surgical hemostasis, negative pressure wound therapy was very helpful in favoring healing of the large and deep wound. PMID:25761194

    Ten children, aged 4 to 14 years, sustaining blunt arterial trauma from motor vehicle collisions (6), bicycle accidents (2), and falls (2) were identified over a 10-year period. The arteries injured included the common iliac (3), abdominal aorta (2), carotid (2), brachial (2), and the subclavian, renal, and femoral artery (1 each). One patient had three arterial injuries. Six patients had associated injuries including a pelvic and lumbar spine fracture, Horner's syndrome, liver laceration, skull fracture, open humerus fracture, small bowel serosal tear, and a brachial plexus injury. Definitive diagnosis was made using arteriography (6), computed tomography (CT) scan (2), and physical examination (2). The types of arterial injuries found included incomplete transection, complete transection with pseudo-aneurysm formation, traumatic arteriovenous (AV) fistulas, complete occlusion, and dissection. Repair was accomplished by hypogastric artery interposition or bypass grafting, synthetic grafting with polytetrafluoroethylene (PTFE), reverse saphenous vein grafting, or primary repair, depending on the circumstances. An AV fistula between the carotid artery and cavernous sinus was embolized. All grafts remained patent with exception of the aorto-renal bypass graft at follow-up ranging from 1 month to 3 years. The principles for repairing vascular injuries in children are slightly different than those in adults. Every effort should be made to use autogenous tissue such as the hypogastric artery or saphenous vein for repair if possible. If not, PTFE grafts can be used, although the long-term patency of these grafts in growing children is not known. PMID:15156954

    A 70-year-old woman presented to our outpatient clinic with a large idiopathic renal arteriovenous fistula (AVF). Transcatheter arterial embolization (TAE) using interlocking detachable coils (IDC) as an anchor was planned. However, because of markedly rapid blood flow and excessive coil flexibility, detaching an IDC carried a high risk of migration. Therefore, we first coiled multiple loops of a microcatheter and then loaded it with an IDC. In this way, the coil was well fitted to the arterial wall and could be detached by withdrawing the microcatheter during balloon occlusion ('pre-framing technique'). Complete occlusion of the afferent artery was achieved by additional coiling and absolute ethanol. This technique contributed to a safe embolization of a high-flow AVF, avoiding migration of the IDC.

    Introduction Systemic atherosclerosis can result in both coronary artery disease (CAD) and carotid artery disease. Recently it has been shown that patients with CAD have a higher incidence of microembolization during carotid artery stenting (CAS), and it has been hypothesized that they could be at higher risk in this intervention. Material and methods We retrospectively evaluated an institutional registry with 437 consecutive patients who underwent coronary angiography and CAS to evaluate their short-term outcomes and long-term survival with regard to the presence of coexisting multivessel coronary artery disease (MVD). Results We performed 220 CAS procedures in MVD patients and 318 CAS procedures in non-MVD patients. The incidence of in-hospital CAS-related adverse events was 2.7% and 2.5% in the MVD and non-MVD groups, respectively (p = 0.88). At 30 days, there was no significant difference between the groups in terms of the number of patients with adverse events (hierarchically death/stroke/myocardial infarction; 8.8% vs. 5.5%; p = 0.18). The median duration of follow-up was 4.23 years. Survival free of all-cause mortality at 1, 3 and 5 years was 90% (95% CI: 86–94%), 79% (95% CI: 73–85%) and 70% (95% CI: 64–77%), and 92% (95% CI: 89–95%), 85% (95% CI: 80–90%) and 76% (95% CI: 70–82%) for the MVD and non-MVD groups (p = 0.02), respectively. Conclusions These results suggest that patients with MVD combined with carotid artery disease are probably not at higher risk of early post-CAS adverse clinical events, but they have significantly worse long-term survival rates.

    We report two cases of proximal posterior cerebral artery (PCA) aneurysms treated with endovascular parent artery occlusion (PAO) with coils. In both cases, selective injection from the 4 F distal access catheter clearly showed the perforating arteries arising from the PCA. Case No 1, a 49-year-old woman, was successfully treated with preservation of a paramedian artery. Case No 2, a 54-year-old woman, was treated in the same manner. The patient underwent extensive thalamic infarction after the procedure because of paramedian artery occlusion. Endovascular PAO with coils is feasible for proximal PCA aneurysms; however, preservation of perforating arteries arising from the PCA is mandatory. PMID:25969452

    The major puncture-site complications of the transfemoral approach are retroperitoneal bleeding (RPB), arteriovenous (AV) fistula, and arterial pseudoaneurysm. Although the management of RPB and AV fistula depends on individual cases, our experience shows that the use of a covered stent with intravascular ultrasound (IVUS) guidance can successfully manage percutaneous coronary intervention-associated RPB and AV fistula. IVUS guidance can therefore make it easy to use an optimal-size covered stent. PMID:27250054

    Methods: A 63-year-old woman with atrial fibrillation presented clinical symptoms and signs of acute ischemia in the right lower extremity on the 17th postoperative day after revision total hip arthroplasty of the left hip for aseptic loosening of femoral component. Aspirin was discontinued 7 days before surgery. Both computed tomography angiography and digital subtraction angiography demonstrated complete occlusion of the right common iliac artery. An emergency catheter-directed thrombolysis with urokinase combined with balloon angioplasty was performed to obtain complete patency of the right common iliac artery. Results: The patient received anticoagulation and antiplatelet therapy postoperatively and was fine at the 2-year follow-up. Conclusions: This case demonstrated that catheter-directed thrombolysis combined with balloon angioplasty could be an efficacious, minimally invasive approach for the treatment of acute embolic occlusion of the common iliac artery. Preoperative anticoagulation for patients undergoing total hip arthroplasty with long-term use of aspirin for atrial fibrillation needs further investigation.

    Traumatic internal carotid artery dissection secondary to blunt trauma is a rare event accounting for 0.08 to 0.4% of all traumatic lesions. The spectrum of traumatic lesions that can affect the internal carotid artery includes minor lesions like spasm, intimal tears, or mural contusions and serious lesions like pseudoaneurysms and complete occlusion. Delayed clinical presentation is typical and can include headache, hemiparesis, partial Horner's syndrome, and cranial nerve palsy. Embolization secondary to the dissection can have devastating effects because it may cause ischemic stroke. Traumatic internal carotid artery dissection after safety belt trauma is very rare; it is usually due to direct cervical trauma on the side of the shoulder fixation point, which causes external bruising along the pathway of the safety belt. We present two cases of traumatic internal carotid artery dissection with concomitant cerebral infarcts caused by safety belts; we discuss the clinical, diagnostic, and therapeutic aspects of this lesion.

    Summary The Pipeline embolization device (PED) is one of the flow-diverting stents approved for the treatment of unruptured large or wide-necked cerebral aneurysms in 2011 1. Its use has now been extended to the treatment of recently ruptured dissecting cerebral aneurysm, carotid pseudoaneurysm from radiation injury, and blister aneurysms 2,3. We aimed to evaluate the effectiveness of utilizing the PED as a primary treatment for ruptured dissecting intracranial aneurysms. A single center retrospective review was conducted for all patients primarily treated with PED for acute subarachnoid hemorrhage (SAH) from ruptured dissecting cerebral aneurysms between December 2010 and February 2013. Patients were followed up with CT angiogram (CTA) or digital subtraction angiogram (DSA). Eight patients with a total of eight dissecting aneurysms were identified. The mean duration from SAH to treatment was 2.5 days. Six of the aneurysms arose from vertebral arteries and two from the basilar artery. Immediate check-DSA confirmed satisfactory contrast stasis in all eight cases, and complete aneurysmal obliteration was achieved at six months. There were two (25%) procedure-related complications, but no major procedure-related complications, such as thromboembolic events or rebleeding from aneurysm were encountered. The PED is a feasible treatment option for ruptured dissecting cerebral aneurysms in acute phase. According to our experience, using PED as flow-diverters in acute SAH does not significantly increase the complication risks or mortality rate if the antiplatelet regime is carefully monitored. Future studies shall evaluate the optimal antiplatelet regimen for using the PED in the acute phase. PMID:25207906

    The stimulation of endothelial cells by arterial wall shear stress (WSS) plays a central role in restenosis. The fluid-structure interaction between stent wire and blood flow alters the WSS, particularly between stent struts. We have designed an in vitro model of struts of an intra-vascular prosthesis to study blood flow through a 'stented' section. The experimental artery consisted of a transparent square section test vein, which reproduced the strut design (100x magnifying power). A programmable pump was used to maintain a steady blood flow. Particle image velocimetry method was used to measure the flow between and over the stent branches, and to quantify WSS. Several prosthesis patterns that were representative of the total stent strut geometry were studied in a greater detail. We obtained WSS values of between -1.5 and 1.5Pa in a weak SS area which provided a source of endothelial stimulation propitious to restenosis. We also compared two similar patterns located in two different flow areas (one at the entry of the stent and one further downstream). We only detected a slight difference between the weakest SS levels at these two sites. As the endothelial proliferation is greatly influenced by the SS, knowledge of the SS modification induced by the stent implantation could be of importance for intra-vascular prostheses design optimisation and thus can help to reduce the restenosis incidence rate.

Data from patients meeting the criterion were examined. CTP was performed and K(trans) maps were used to assess the permeability values in HT and non-HT regions. A receiver operating characteristic (ROC) curve was calculated, showing the sensitivity and specificity of K(trans) for predicting HT risk. Composite images were produced to illustrate the spatial correlations among perfusion, permeability changes and HT. This study examined 41 patients. Twenty-six patients had hemorrhagic infarction and 15 had parenchymal hemorrhage. The mean K(trans) value in HT regions was significantly lower than that in the non-HT regions (0.26 ± 0.21/min vs. 0.78 ± 0.64/min; P < 0.001). The ROC curve analysis identified an optimal cutoff value of 0.334/min for K(trans) to predict HT risk. Composite images suggested ischemic regions with low permeability, or the mismatch area of low perfusion and high permeability, more likely have HT. HT regions after intra-arterial thrombolysis had lower permeability values on K(trans) maps. The mismatch area of lower perfusion and higher permeability are more likely to develop HT. PMID:27302077

    An 84-year-old woman with a history of hypertension and coronary artery disease was admitted with a progressively worsening diffuse abdominal pain. Computed tomography scan of the abdomen and angiography revealed occlusion of the origin and proximal portion of superior mesenteric artery. Aortography also showed severe origin stenosis of inferior mesenteric artery and that the distal part of the superior mesenteric artery was supplied by a prominent marginal artery of Drummond. Patient was effectively treated with percutaneous transluminal angioplasty and stenting of the inferior mesenteric artery. Follow-up imaging studies demonstrated patency of the stent and spontaneous recanalization of superior mesenteric artery occlusion.

    We retrospectively evaluated low brachial artery puncture for arteriography and its complications as an alternative approach route for bilateral lower extremity run-off. Using the Seldinger technique and catheterization with a sheathless 4-F multiple side-hole pigtail catheter, we performed 2250 low brachial artery punctures in outpatients.The right brachial artery (RBA) was successfully punctured in 2039 patients; the left brachial artery (LBA) in 200. The transfemoral approach was used in 11 patients when catheterizing either of brachial arteries failed. Ten major or moderate complications (2 pseudoaneurysms, 2 thrombosis, 1 dissection and 5 hematomas) were encountered. Surgical intervention was necessary in three cases. There were no transient ischemic attacks. Twenty-one patients suffered temporary loss of radial pulse which returned spontaneously in less than 1 hour. One patient demonstrated prolonged loss of pulse which required heparin. Low brachial artery puncture and catheterization at the antecubital fossa is a very safe and cost-effective alternative to the femoral artery approach for lower extremity intra-arterial arteriography in the hands of experienced operators. The success rate in catheterizing one of the brachial arteries was 99.52% with a low significant complications rate of 0.44%. The transbrachial approach should be used as a standard method for lower extremity IA - DSA in an outpatient setting.

  14. Case report: parenchymal pseudoaneurysm of a renal allograft after core needle biopsy: a rare cause of allograft injury.

    There are multiple causes of worsening graft function after initial good function in cadaveric kidney transplant. In this report, we discuss a rare one: a traumatic pseudoaneurysm caused by a 14-gauge core needle biopsy in a 55-year-old woman. She had immediate graft function followed by rapid decline in the first postoperative week. Imaging studies showed an intraparenchymal 2-cm pulsatile mass with turbulent blood flow in the upper pole at the corticomedullary junction. Angiography the following morning confirmed the diagnosis of pseudoaneurysm. It was coiled successfully, with restoration of graft function. Although development of a pseudoaneurysm is a rare event, transplant centers must be cognizant of allograft injuries like this one. PMID:21911162

    A new concept--Tissue Requisitions (Principle I)/Relinquishes (Principle II) Arterial Supply--of TRAS principles is introduced to help appreciate the failures/successes of modern medicine's attempts at restoring arterial flow in luminally compromised coronary/carotid fields, an invasive branch rightly called vascular ReRheology, which comprises diagnosing/treating arterial blocks. The technical wizardry of arterial reconstruction (bypass) or lumen--restoration (plasty) has to reckon with the TRAS principles all the time. PMID:10740714

    Patients with pulmonary arterial hypertension (PAH) usually show improvements in symptoms, exercise capacity, and hemodynamics after treatment with approved medical therapies. This study sought to determine whether improvement in right-sided cardiac function measured using cardiac magnetic resonance imaging would also be seen and whether these changes would correlate with improvement in exercise capacity. Sixteen patients with PAH underwent evaluation at baseline and after 12 months of treatment with bosentan. After treatment, cardiac index, pulmonary vascular resistance, and 6-minute walk distance improved, and there was a trend toward improvement in right ventricular (RV) stroke volume (70 +/- 27 to 81 +/- 30 ml; p = 0.08), but no change in RV ejection fraction (RVEF) or RV end-diastolic volume. Six-minute walk distance improved by 59 m (p <0.05) in the overall cohort and improved more in patients in whom RVEF increased compared with those with stable or decreased RVEF (+98 vs -37 m, respectively; p = 0.01). Three patients died during follow-up, and these patients had significantly lower RVEF and left ventricular end-diastolic volume indexes than surviving patients. In conclusion, these results suggest that cardiac magnetic resonance imaging may have value in determining response to therapy and prognosis in patients with PAH. PMID:18489949

    We here report the results of a Phase I/IIa open-label four dose-escalation clinical study assessing the safety, tolerability, and possible therapeutic efficacy of a single intramuscular administration of DVC1-0101, a new gene transfer vector based on a nontransmissible recombinant Sendai virus (rSeV) expressing the human fibroblast growth factor-2 (FGF-2) gene (rSeV/dF-hFGF2), in patients with peripheral arterial disease (PAD). Gene transfer was done in 12 limbs of 12 patients with rest pain, and three of them had ischemic ulcer(s). No cardiovascular or other serious adverse events (SAEs) caused by gene transfer were detected in the patients over a 6-month follow-up. No infectious viral particles, as assessed by hemagglutination activity, were detected in any patient during the study. No representative elevation of proinflammatory cytokines or plasma FGF-2 was seen. Significant and continuous improvements in Rutherford category, absolute claudication distance (ACD), and rest pain were observed (P < 0.05 to 0.01). To the best of our knowledge, this is the first clinical trial of the use of a gene transfer vector based on rSeV. The single intramuscular administration of DVC1-0101 to PAD patients was safe and well tolerated, and resulted in significant improvements of limb function. Larger pivotal studies are warranted as a next step. PMID:23319060

    A 53-year-old woman with liver cirrhosis and hepatocellular carcinoma underwent living donor liver transplantation. After transplantation, her hemoglobin and hematocrit levels decreased to 6.3 g/dl and 18.5%, respectively, during the course of 3 days. A contrast-enhanced abdominal computed axial tomography (CAT) scan showed a hemoperitoneum in the right perihepatic space with no evidence of abdominal wall hematoma or pseudoaneurysm formation. An angiogram of the deep circumflex iliac artery (DCIA) showed extravasation of contrast media along the surgical drain, which had been inserted during the transplantation procedure. Transcatheter embolization of the branches of the DCIA was successfully performed using N-butyl cyanoacrylate.

    Traumatic intracranial aneurysm in the proximal part of the anterior cerebral artery in the pediatric population has not been documented so far. Here we report the case of a 4 year-old child who developed a pseudo-aneurysm after minor head trauma and was managed successfully with trapping of the aneurysm. A ventriculo-peritoneal shunt was placed as the child became dependent on extraventricular drain during the post-operative period. The patient made excellent recovery in neurological status within 1 month of post-operative clinical follow up.
