A 36-year-old male presented with progressive exertional dyspnea over months. Physical examination showed jugular venous distension, lung crecipitations, femoral bruit and pitting pedal edema. Echocardiogram showed a dilated right ventricle with severe pulmonary hypertension and a non collapsing inferior vena cava (IVC). On right heart catheterization, IVC oxygen saturation was noted at 92% suggesting arterial mixing; a computed tomography of the abdomen showed a fistula between the right common iliac artery to the right common iliac vein at L4 level and a massive IVC; this was linked to trauma from a disectomy done 16 years ago at L4-L5 level...

Biliovenous fistula occurs due to development of a communication between hepatic duct and portal vein branches and is a rare complication of percutaneous transhepatic biliary drainage (PTBD). Most of them are self-limiting and only occasionally they need interventional management. Placement of biliary stent graft is a viable option. We present here a case of a 56-year-old male with carcinoma of gall bladder presenting with hemodynamic shock due to severe hemobilia after PTBD and treated successfully by biliary covered stent placement...

OBJECTIVES: Parkes Weber syndrome is a congenital vascular malformation which consists of capillary malformation, venous malformation, lymphatic malformation, and arteriovenous malformation. Although Parkes Weber syndrome is a clinically distinctive entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome that consists of the triad capillary malformation, venous malformation, and lymphatic malformation. METHODS: We performed a systematic review investigating clinical, diagnostic, and treatment modalities of Parkes Weber syndrome (PubMed/MEDLINE, Embase, and Cochrane databases)...

Profuse bleeding originating from an injured cerebral sinus can be a harrowing experience for any surgeon, particularly during an operation on a young child. Common surgical remedies include sinus ligation, primary repair, placement of a hemostatic plug, and patch or venous grafting that may require temporary stenting. In this paper the authors describe the use of a contoured bioresorbable plate to hold a hemostatic plug in place along a tear in the inferomedial portion of a relatively inaccessible part of the posterior segment of the superior sagittal sinus in an 11-kg infant undergoing hemispherotomy for epilepsy...

Hepatic venous outflow obstruction (HVOO) is a rare complication after liver transplantation (LT) associated with significant morbidity and reduced graft survival. Endovascular intervention has become the first-line treatment for HVOO, but data on long-term outcomes are lacking. We have analysed outcomes after endovascular intervention for HVOO in 905 consecutive patients who received 965 full-size LT at our unit from January 2007 to June 2014. There were 27 (3%) patients who underwent hepatic venogram for suspected HVOO, with persistent ascites being the most common symptom triggering the investigation (n = 19, 70%)...

OBJECTIVE: The aim of the study was to evaluate the feasibility and mid-term biological behavior of the novel customized aortic repair (CAR) method for endovascular aneurysm treatment. METHODS: CAR consists of exclusion of an aneurysm from the circulation using a custom-designed dog bone-shaped balloon, followed by aneurysm sac filling with an in situ curing polymer. After curing and balloon deflation, the circulation is restored through a patent cast neolumen. A liquid two-component polymer was injected via a small bore catheter under X-ray control into a surgically created aneurysm...

OBJECTIVE: Detailed analyses of clinical characteristics of myocardial infarction (MI) as an essential thrombocythemia (ET)- and polycythemia vera (PV)-related complication have been so far presented mostly as case reports. Therefore, the aim of this retrospective analysis was to evaluate the main cardiological and hematological characteristics for better understanding myocardial complications in ET/PV. METHODS: A retrospective analysis was carried out involving 263 patients diagnosed with ET or PV (155/108) between 1998 and 2014...

BACKGROUND: The initial therapy for a stenosis in an arteriovenous fistula used for haemodialysis is radiological balloon dilatation or angioplasty. The benefit of angioplasty is often short-lived, intervention-free survival is reported to be 40-50 % at 1 year. Previous small studies and observational data suggest that paclitaxel-coated balloons may be of benefit in improving outcomes after fistuloplasty of stenotic arteriovenous fistulae. METHODS/DESIGN: We have designed a multicentre, double-blind randomised controlled trial to test the superiority of paclitaxel-coated balloons for preventing restenosis after fistuloplasty in patients with a native arteriovenous fistula...

OBJECTIVE: The number of older patients with acute aortic dissection type A (AAD [A]) is increasing as the population ages. We evaluated clinical outcomes for octogenarians with AAD (A) treated surgically at our hospital. Whenever possible, we limited the replacement site of the ascending aorta to the supracoronary and hemiarch. METHODS: Of 436 patients with AAD (A) seen in our hospital emergency room between April 2001 and August 2015, 90 were octogenarians. Surgery was performed using a simple cardiopulmonary bypass established through the right femoral artery and venous cannulation, and distal anastomosis was performed under deep hypothermic circulatory arrest at 20°C...

An arteriovenous fistula (AVF) is an abnormal connection between an artery and a vein. Double-lumen catheters are widely used for gaining temporary access in patients requiring acute hemodialysis (HD). Several complications are associated with the insertion of these catheters, including bleeding, infection, arterial injuries, and deep venous thrombosis. An iatrogenic AVF is a rare and severe complication following catheterization for temporary HD. Here, we report the case of a patient who developed an iatrogenic AVF following catheterization for acute HD resulting in acute bleeding...

A 43-year-old man with liver cirrhosis received transjugular intrahepatic portosystemic shunt (TIPS) for the treatment of recurrent variceal bleeding and F3 esophageal varices. During routine follow up liver ultrasound examination, six months after the implantation, TIPS occlusion was suspected and TIPS revision was performed. During the revision, moderate to severe stenosis at the hepatic venous segment of the tract and a total occlusion at the parenchymal segment of TIPS tract near the portal vein with biliary-TIPS fistula were identified with a clear visualization of the common bile duct...

PURPOSE: To compare patency in dialysis patients following different endovascular treatment of symptomatic central venous stenosis. MATERIALS AND METHODS: A 10-year retrospective evaluation in 70 patients (32 men) dialyzing through vascular access (33, 47%) and tunneled catheters (37, 53%) was made. Three cohorts were compared: angioplasty alone (22), bare metal stent (28), and stent graft (20). Patencies were described with Kaplan-Meier method, and Cox uni- and multivariate models were analyzed to find factors associated...

BACKGROUND: Hepatic venous outflow is important for graft survival in living donor liver transplantation (LDLT). If hepatic venous outflow obstruction occurs, hepatic vein stenting is considered to restore the patency. PURPOSE: To retrospectively evaluate the efficacy and patency of primary hepatic vein stenting for hepatic venous outflow obstruction (HVOO) after LDLT. MATERIAL AND METHODS: Percutaneous interventions, including hepatic vein stent placement with or without balloon angioplasty, were performed in 21 patients who had undergone LDLT and had HVOO confirmed through hepatic venography or manometry, including the patients who had a structural abnormality...

Surgically placed dialysis access is an important component of dialysis replacement therapy. The vast majority of patients undergoing dialysis will have surgically placed accesses at some point in the course of their disease, and for many patients these accesses may represent their definitive renal replacement option. Most, if not all, arteriovenous fistulae and grafts will require interventions at some point in time. Percutaneous angioplasty is the typical first treatment performed for venous stenoses, with stents and stent grafts being reserved for patients in whom angioplasty and surgical options are exhausted...
