Incidence and diagnosis of deep vein thrombosis associated with pregnancy.
Kierkegaard, A
1983-01-01
The incidence of deep vein thrombosis (DVT), diagnosed by ascending phlebography, has been calculated retrospectively in a group of 14 869 obstetrical patients. The incidence was calculated to 0.13 per thousand antepartum and 0.61 per thousand postpartum. The study revealed that clinical signs and symptoms of thrombosis are very unreliable in pregnant women but more reliable in puerperal women. It is concluded that objective diagnosis of thrombosis is important in pregnant women, and ascending phlebography is a rewarding objective method to use in pregnant women.

The influence of chronic synovial inflammation and effusion on the juxta-articular bone haemodynamics in the juvenile knee was studied in 12 immature dogs with Carragheenin-induced unilateral arthritis. Using a fluid filled electromanometric pressure recording system simultaneous pressure measurements were taken from the distal femoral metaphysis, juxta-articular epiphyses and knee joint cavity in general anaesthesia followed by intraosseous phlebographies. During resting conditions the intraosseous pressure of the distal femoral epiphysis and the intra-articular pressure was significantly elevated. The phlebographies showed increased accumulation of contrast in arthritic femoral epiphyses with decreased contrast clearance rate. During increasing intra-articular pressure an augmented vulnerability of the blood supply of the arthritic femoral epiphyses was demonstrated. The results suggests that joint effusion may play an important role in the bone changes in juvenile degenerative arthritis of the knee.

Knowledge of the anatomy of the pelvic, gonadal and renal veins is important to understand pelvic congestion syndrome (PCS) and left renal vein compression syndrome (LRCS), which is also known as the nutcracker syndrome. LRCS is related to PCS and to the presence of vulvar, vaginal and pudendal varicose veins. The diagnosis of the two syndromes is difficult, and usually achieved with CT- or phlebography. The gold standard is the intravenous pressure measurement using conventional phlebography. The definition of PCS is described as pelvic pain, aggravated in the standing position and lasting for more than 6 months. Pain in the left flank and microhaematuria is seen in patients with LRCS. Women with multiple pregnancies are at increased risk of developing varicose vein recurrences with pelvic drainage and ovarian vein reflux after crossectomy and stripping of the great saphenous vein. The therapeutic options are: conservative treatment (medroxyprogesteron) or interventional (coiling of the ovarian vein) or operative treatment (clipping of the ovarian vein). Controlled prospective trials are needed to find the best treatment.

[Superior vena cava syndrome--clinical aspects, etiology and case reports].
Serdarevic, M; Löhr, E; Reidemeister, J C
1984-06-01
The so-called superior-Cava Syndrome is caused by obstructions by centrally localized tumors by thrombosis or by inflammations of the mediastinum. In cases of tumorous infiltration a graft can be inserted. The different phenomena of thrombosis caused by nutritial catheters and pace makers are of clinical importance. Acute thrombosis of the brachio-cervical veins and the Vena Cava can be treated successfully by means of thrombolysis. Besides CT bilateral brachial phlebography communicates optimal information concerning localization of vascular obstruction and collateral circuits.

The May-Thurner syndrome is a well-known anatomical anomaly where the left common iliac vein (LCIV) is compressed between the right common iliac artery and the fifth vertebral body. This report describes the case of a 'right-sided' May-Thurner syndrome where the right common iliac vein (RCIV) is compressed by the left common iliac artery in a patient with a left-sided inferior vena cava (IVC). A 26-year-old woman was admitted to our institution with acute edema of the right lower limb. The diagnosis of May-Thurner syndrome was done by CT scan and confirmed by phlebography. An endovascular treatment with stenting was carriedmore » out, with good patency and clinical result at 12-month follow-up.« less

DOE Office of Scientific and Technical Information (OSTI.GOV)
Oei, H.Y.; Arndt, J.W.; Mali, W.P.T.
1984-01-01
In this study varicocelescintigraphy (VS) is compared to X-ray phlebography(XP). In 104 patients (pts) suspected for varicocele on physical examination, VS was performed using a large field camera and 5 mCi Tc-99m in-vivo labeled erythrocytes. This was done (without Valsalva) in upright position after taping penis to the abdomen, marking the penisbase and covering the thighs with lead. Twenty 5-sec dynamic images (DY) and 5-min static image (ST) were made. Variocele-size was quantitated by bloodpoolvalue (BPV) using digital image of ST. BPV is the ratio of mean counts/pixel in varicocele and right iliac vessels calculated from adjacent pixels with maximummore » counts. On XP varicocele was diagnosed if the testicular vein was visualized after contrast injection given during Valsalva in the renal vein. In 85 pts varicocele was confirmed on XP. In 67 of them this was recognized easily on both DY and ST; the DY shows activity in the varicocele 10-35 sec later than the iliac artery and the ST shows pooling of activity below the penisbase. In 11 pts the varicocele was only seen on ST and in other 5 pts only on DY. In the remaining 2 pts both DY and ST were false negative. The BPV in 72 pts with abnormal DY and in 11 pts with normal DY varied between 0.4 - 2.2(0.89 +- 0.38) resp. 0.4 - 1.0(0.61 +- 0.19). In 16 of the 19 pts who showed no varicocele on XP, VS also was negative; their BPV varied between 0.2 - 0.4(0.30 +- 0.08). However, in 3 pts who initially had a normal XP, varicocele was diagnosed on both DY and ST, which was confirmed when XP was repeated. Diagnosis of varicocele by physical examination is not accurate. VS is suitable for screenings procedure when both DY and ST are obtained. Pts with abnormal DY have larger varicocele than pts with normal DY.« less

A proof-of-concept study of the VeinScrew: A new percutaneous venous closure device.
Boersma, Doeke; de Borst, Gert Jan; Moll, Frans L
2017-02-01
Objective This study evaluated the concept of percutaneous closure of insufficient veins using the VeinScrew principle. Methods The VeinScrew is designed to place a spring-shaped implant that contracts and clamps around the vein. The ability of the device to occlude adequately was tested in a bench model experiment. The feasibility of accurate placement and adequate venous occlusion was evaluated in an animal experiment and in a human cadaveric experiment. Results The VeinScrew implant occluded up to a pressure of 135 mmHg. In vivo studies confirmed that deployment was challenging but technically feasible, and subsequent phlebography showed closure of the vein. The cadaveric study showed that percutaneous placement of the evolved VeinScrew around the great saphenous vein was feasible and accurate. Conclusions The current studies show the feasibility of the VeinScrew concept. Future developments and translational studies are necessary to determine the potential of this technique as a new option in the phlebologist's toolbox.

Uehara, Shuichiro; Osuga, Keigo; Yoneda, Akihiro; Oue, Takaharu; Yamanaka, Hiroaki; Fukuzawa, Masahiro
2009-08-01
Venous malformations (VMs) involve multiple anatomical spaces and encase critical neuromuscular structures, making surgical treatment difficult. Recently sclerotherapy has been suggested as the primary treatment for VMs instead of surgical intervention. This report represents eight cases of children with VMs treated with direct percutaneous injections of sclerosing agents, such as ethanol, polidocanol or ethanolamine oleate. All eight patients had large lesions (>3 cm) located on the head, foot, neck and face. Sclerotherapy was performed in an angiographic suite under general anesthesia. Prior to sclerotherapy, percutaneous phlebography was performed in order to visualize the dynamic situation inside the lesion and the draining flow into the adjacent venous vascular system. A 2-15 ml of sclerosing agent was injected into VM lesions under fluoroscopy. An evaluation by MRI examination showed that 6 out of 8 patients had remission, and alleviation of their symptoms without major complications, furthermore one of the lesions apparently disappeared. Intralesional sclerotherapy provides a simple, safe and effective treatment for VMs in the subcutaneous lesions in children.

Venous interruption for pulmonary embolism: the illustrative case of Richard M. Nixon.
Barker, W F; Hickman, E B; Harper, J A; Lungren, J
1997-07-01
This politically prominent patient was seen in consultation on October 26, 1974 because of chronic venous thrombosis and a recent pulmonary embolism. His problems had begun in 1965 when he developed venous thrombosis in the left leg after a length trip by air. His treatment had been sporadic and his compliance with treatment less than satisfactory. Because of detailed phlebography demonstrating (1) no clots in the veins of the right leg, (2) extensive loose lying clot filling the superficial, deep, and external iliac veins on the left, and (3) because of prior difficulties with patient compliance unilateral interruption of the left external iliac vein above the top of the clot was proposed. Despite some postoperative complications, the patient made a full recovery and lived 19 years on warfarin therapy before death from unrelated causes. He suffered no significant edema or other postphlebitic symptoms in the affected leg. The history of the use of venous interruption under these circumstances is reviewed to justify the operation that was performed.

Pietura, Radosław; Toborek, Michał; Dudek, Aneta; Boćkowska, Agata; Janicka, Joanna; Piekarski, Paweł
2013-01-01
Summary Background: Varicoceles are abnormally dilated veins within the pampiniform plexus. They are caused by reflux of blood in the internal spermatic vein. The incidence of varicoceles is approximately 10–15% of the adolescent male population. The etiology of varicoceles is probably multifactorial. The diagnosis is based on Doppler US. Treatment could be endovascular or surgical. The aim of the study was to describe and evaluate a novel method of endovascular embolization of varicoceles using n-butyl cyanoacrylate (NBCA) glue. Material/Methods: 17 patients were subjected to endovascular treatment of varicoceles using NBCA. A 2.8 Fr microcatheter and a 1:1 mixture of NBCA and lipiodol were used for embolization of the spermatic vein. Results: All 17 procedures were successful. There were no complications. Discussion: Embolization of varicoceles using NBCA glue is efficient and safe for all patients. The method should be considered as a method of choice in all patients. Phlebography and Valsalva maneuver are crucial for technical success and avoidance of complications. Conclusions: Endovascular treatment of varicoceles using NBCA glue is very effective and safe.

Acute appendicitis-like symptoms as initial presentation of ovarian vein thrombosis.
Prieto-Nieto, M I; Perez-Robledo, J P; Rodriguez-Montes, J A; Garci-Sancho-Martin, L
2004-07-01
Postpartum ovarian vein thrombosis is a rare condition, with an incidence rate being 1/600 deliveries. It most often arises in the right ovarian vein. A 33-year-old patient who had had normal vaginal delivery presented with fever, pain in the right iliac fossa, and leukocytosis on the sixth day after delivery. An antibiotic course was instituted but 3 days later symptoms reappeared. Diagnosis of acute appendicitis was made. At surgery through a McBurney incision, a woody tumoration consistent with ovarian vein thrombosis was found. Anticoagulation therapy with heparin and antibiotics were instituted. Phlebography and color Doppler sonography confirmed the presence of thrombosis of both the common femoral iliac and inferior vena cava. Fribrolysis with urokinase was performed. The patient has remained stable and symptom-free over a 4-year follow-up. Ovarian vein thrombosis typically presents with symptoms suggestive of acute appendicitis, as was the case in our patient. Color Doppler sonography is the favored diagnostic procedure, with CT being a supplementary tool. Surgery is not necessary and treatment consists of anticoagulants and antibiotics. Even though postpartum ovarian vein thrombosis is rare, early recognition of the condition is of paramount importance to institute the adequate treatment and avoid potential serious sequelae.

Although surgery for the treatment of hallux valgus is frequently performed, the exact rate of deep vein thrombosis following this procedure is unknown. We performed a single-center, prospective, phlebographically controlled study to quantify the rate of venous thrombosis following operative correction of hallux valgus. Consecutive patients undergoing chevron bunionectomy for correction of hallux valgus deformity were enrolled in the study. Patients with clinical or hematological risk factors for venous thrombosis were excluded. One hundred patients with a mean age of 48.9 years were operated on and did not receive medical prophylaxis against thrombosis. All patients were assessed with phlebography at a mean of twenty-nine days postoperatively. Venous thrombosis was found in four patients (4%). The mean age of these patients (and standard deviation) was 61.7 +/- 6.1 years compared with a mean age of 48.4 +/- 13.9 years for the patients in whom thrombosis did not develop (p = 0.034). Patients are at a low risk for venous thrombosis following surgical treatment of hallux valgus. The need for prophylaxis against thrombosis should be calculated individually for each patient according to his or her known level of risk. Routine medical prophylaxis against thrombosis might be justified for patients over the age of sixty years.

This case report concerns a child admitted to the County Hospital of Zalaegerszeg with the symptoms of ataxia, focal convulsions and hemiparesis. Anticonvulsive therapy abolished the epileptic manifestations, but hemiparesis remained unchanged. At the age of six and half years progressive venous thrombosis developed first on the left and some days later on the right lower limb. Phlebography revealed on both sides thrombosis of the vena iliaca which led to stenosis of the right femoral vein and dilated venous collaterals on the abdomen and right thigh. Coeliacography showed an enlarged spleen and varicosity around the portal vein. Later thrombosis of the arteria dorsalis pedis developed indicated by the gangrene the fifth toe. At this stage the child was transfered to the Pediatric Department of the University of Pécs for further evaluation. Examination of the hemostasis showed hypercoagulability due to antithrombin III deficiency pointing towards a common cause, namely thromboembolism of the earlier and recent clinical manifestations. A reduced activity of the antithrombin III was also observed in the mother and two sisters of the child. The response to Syncumar therapy was beneficial, arterial thrombosis regressed and no further thromboembolic complications developed.

Nowadays, compression ultrasonography (CUS) is the gold standard for the routine diagnosis of deep venous thrombosis (DVT). The drawback of CUS is the low sensitivity concerning the diagnosis of isolated pelvic vein thrombosis, especially referring to isolated internal iliac vein and ovarian vein thromboses. Therefore, magnetic resonance (MR) venography has become a valuable alternative. We present the case of a 45-year-old female patient with a massive pulmonary embolism with the indication for thrombolytic therapy due to severe right ventricular overload. We were not able to detect a DVT in the lower limbs of this patient with CUS. However, further DVT workup by MR venography showed a free-floating thrombus formation originating from the right internal iliac veins into the inferior vena cava. Owing to the fact that this thrombus was free floating, surgical removal of the thrombus was scheduled and performed successfully. In some patients it might be important to look for so-called rare causes of pulmonary embolism, even when CUS of the lower limbs does not reveal any DVTs. The diagnostic procedure of choice for these patients seems to be MR phlebography, as iliac and pelvic veins can be evaluated without radiation exposure with this procedure.

To analyze our experience with antegrade sclerotherapy for the treatment of Coolsaet types I, II, and III varicoceles in a pediatric and adolescent population. Between 2005 and 2015, 73 patients who underwent antegrade sclerotherapy were retrospectively evaluated. Patient age, side, clinical and Doppler ultrasound grade, and anatomical variations were collected. Varicoceles were grouped following Coolsaet's classification: all types were sclerosed. Follow-up consisted in clinical examination 3 and 6 months following surgery and testicular Doppler ultrasound 6 and 12 months following surgery. Patients were then telephonically interviewed. Success was defined as varicocele resolution or reduction to a grade not requiring surgery. Mean patient age was 14.7 years and mean operating time was 50.8 minutes. Based on phlebographic imaging and following Coolsaet's classification, we identified 57 (78.1%) type I, 3 (4.1%) type II, and 13 (17.8%) type III varicoceles. No intraoperative complications were observed. Three patients (4.1%) presented a short-term complication in the form of pampiniform plexus thrombosis; 1 patient also developed wound dehiscence: all complications occurred in Coolsaet type I varicoceles and during surgeon learning curve. No hydrocele occurred. Out of 59 patients with a satisfactory follow-up (range: 14 months-10 years), 2 recurrences occurred, the success rate thus being 96.6%. Tauber's antegrade sclerotherapy is a simple and feasible technique, effective in treating all kinds of varicocele with low complication, recurrence, and persistence rates. Phlebography reveals frequent venous anatomical variations, allows grouping of varicoceles into Coolsaet types, and enables performing of sclerosis safely in all 3 kinds.

To evaluate the SailValve, a new self-expanding deep venous valve concept based on a single polytetrafluoroethylene cusp floating up and down in the bloodstream like a sail, acting as a flow regulator and allowing minimal reflux to reduce thrombogenicity. Both iliac veins of 5 pigs were implanted with SailValve devices; the first animal was an acute pilot experiment to show the feasibility of accurately positioning the SailValve via a femoral access. The other 4 animals were followed for 2 weeks (n=2) or 4 weeks (n=2) under a chronic implantation protocol. Patency and valve function were evaluated directly in all animals using ascending and descending phlebography after device placement and at termination in the chronic implant animals. For reasons of clinical relevance, a regimen of clopidogrel and calcium carbasalate was administered. Histological analysis was performed according to a predefined protocol by an independent pathologist. Deployment was technically feasible in all 10 iliac veins, and all were patent directly after placement. No perioperative or postoperative complications occurred. Ascending phlebograms in the follow-up animals confirmed the patency of all valves after 2 or 4 weeks. Descending phlebograms showed full function in 5 of 8 valves. Limited reflux was seen in 1 valve (4-week group), and the function in the remaining 2 valves (2-week group) was insufficient because of malpositioning. No macroscopic thrombosis was noted on histology. Histology in the follow-up groups revealed a progressive inflammatory reaction to the valves. This animal study shows the potential of the SailValve concept with sufficient valve function after adequate positioning and no (thrombogenic) occlusions after short-term follow-up. Future research is essential to optimize valve material and long-term patency.

In a randomized, prospective trial, a low-molecular-weight heparinoid (Org 10172 (Lomoparan)) was compared with warfarin for efficacy and safety in preventing deep-vein thrombosis in 263 patients who had an operatively treated fracture of the hip. One group of patients received Org 10172 in a dose of 750 units subcutaneously every twelve hours until the ninth postoperative day; on the seventh postoperative day, warfarin was added to the regimen. The other group received only warfarin. Both drugs were begun preoperatively, immediately after the admission evaluation. In the patients who received warfarin, the desired prothrombin time was one and one-half times themore » control level. Deep-vein thrombosis was detected by {sup 125}I-fibrinogen scanning and impedance plethysmography and was confirmed by phlebography and compression ultrasonography. Deep-vein thrombosis was found in nine (7 per cent) of the 132 patients who received Org 10172 and in twenty-eight (21 per cent) of the 131 patients who received warfarin (p less than 0.001). Adverse reactions were not significantly different in the two groups. Major bleeding complications occurred in eight patients in the Org-10172 group, only four of whom were receiving the drug at the time of bleeding, and in five patients who were receiving warfarin (not significant). There was no difference in intraoperative loss of blood or in requirements for transfusion. We concluded that the low-molecular-weight heparinoid Org 10172 is a safe, convenient, effective antithrombotic agent for the prevention of venous thrombosis after an operation for fracture of the hip.« less

To determine the feasibility and safety of establishing a porcine hepatic cirrhosis and portal hypertension model by hepatic arterial perfusion with 80% alcohol. Twenty-one healthy Guizhou miniature pigs were randomly divided into three experimental groups and three control groups. The pigs in the three experimental groups were subjected to hepatic arterial perfusion with 7, 12 and 17 mL of 80% alcohol, respectively, while those in the three control groups underwent hepatic arterial perfusion with 7, 12 and 17 mL of saline, respectively. Hepatic arteriography and direct portal phlebography were performed on all animals before and after perfusion, and the portal venous pressure and diameter were measured before perfusion, immediately after perfusion, and at 2, 4 and 6 wk after perfusion. The following procedures were performed at different time points: routine blood sampling, blood biochemistry, blood coagulation and blood ammonia tests before surgery, and at 2, 4 and 6 wk after surgery; hepatic biopsy before surgery, within 6 h after surgery, and at 1, 2, 3, 4 and 5 wk after surgery; abdominal enhanced computed tomography examination before surgery and at 6 wk after surgery; autopsy and multi-point sampling of various liver lobes for histological examination at 6 wk after surgery. In experimental group 1, different degrees of hepatic fibrosis were observed, and one pig developed hepatic cirrhosis. In experimental group 2, there were cases of hepatic cirrhosis, different degrees of increased portal venous pressure, and intrahepatic portal venous bypass, but neither extrahepatic portal-systemic bypass circulation nor death occurred. In experimental group 3, two animals died and three animals developed hepatic cirrhosis, and different degrees of increased portal venous pressure and intrahepatic portal venous bypass were also observed, but there was no extrahepatic portal-systemic bypass circulation. It is feasible to establish an animal model of hepatic cirrhosis and portal hypertension by hepatic arterial perfusion with 80% alcohol, however, the safety of this model depends on a suitable perfusion dose.

The aim of this study was to compare the technical success between left spermatic vein (LSV) scleroembolisation achieved with the injection of sclerosant through a diagnostic catheter and through an occluding balloon (OB), in the treatment of male varicocele. From January 2012 to September 2013, we prospectively enrolled 100 patients with left varicocele and an indication for LSV scleroembolisation related to symptoms or spermiogram anomalies; patients were randomised to two groups (we wrote a list of 100 lines assigned casually with A or B and each patient was consecutively allocated to group A or B on the basis of this list). Patients in group A underwent injection of the sclerosing agent through an angiographic diagnostic catheter (free catheter technique) and patients in group B through an OB catheter (OB technique). In cases of incomplete occlusion of the LSV, the procedure was completed with coils. Total occlusion of the LSV at post-treatment phlebography during a Valsalva manoeuvre before any coil embolisation was considered a technical success. The rate of complications was also evaluated. The Fischer's test was used for statistical analysis. We evaluated a total of 90 patients because five patients for each group were not included in the statistical analysis owing to technical problems or complications. In group A we had a technical success of 75.6 versus 93.4 % in group B, and the difference was statistically significant (P = 0.003); in particular, we had to complete the embolisation with insertion of coils in 11 cases (24.4 %) in group A, and in three cases in group B (6.6 %). In group A, LSV rupture occurred in four cases (8 %) so the procedure was completed by sclerosant injection through the OB located distally to the lesion. These patients were not considered for evaluation. In another case, a high flow shunt towards the inferior vena cava was detected, so the patient underwent OB injection to stop the flow to the shunt, and was not included for statistical evaluation. In group B, vein rupture with contrast leakage was noted in six cases (12 %); nonetheless, all the procedures were completed because the OB was positioned distally to the vessel tear, obviating any retrograde leakage of sclerosant. In group B, in five cases (10 %), we were unable to advance the OB though the LSV ostium so the procedures were completed with the diagnostic catheter and not considered for statistical evaluation. On the basis of our data, the embolisation of the LSV obtained by injecting the sclerosant through an OB rather than through a diagnostic catheter seems to be more effective in achieving total vein embolisation, as well as allowing a controlled injection of sclerosant even in cases of vein rupture.
