Factor VIII is a common acute phase reactant and elevated levels confer an increased risk of thrombosis. Such thrombotic events have been documented in the literature, though to a limited extent. We present the case of a 54-year-old man presenting with a non-Q-wave myocardial infarction who was found to have triple vessel disease and subsequently underwent a 4-vessel coronary artery bypass grafting (CABG). Postoperatively, he was found to have multiple occluded vessels, deep vein thromboses, and a cerebrovascular accident (CVA)...

BACKGROUND: The widespread use of central venous catheters, ports, pacemakers, and defibrillators has increased the incidence of benign superior vena cava syndrome (SVCS). This study aimed at reviewing the results of open and endovascular treatment of SVCS. METHOD: Medical literature databases were searched for relevant studies. Studies with more than five adult patients, reporting separate results for the SVC were included. Nine studies reported the results of endovascular treatment of SVCS including 136 patients followed up for a mean of 11-48 months...

BACKGROUND: Bioengineered living autologous valves with remodeling and growth capacity represent a promising concept for future cardiac and venous valve repair. A meticulous understanding of the mechanisms involved in recellularization and remodeling is essential for the safe and efficient clinical translation of this technology. In this context, the first investigations of bioengineered vascular grafts in immune-incompetent or transgenic rodents represented an important step. However, the in-vivo assessment of bioengineered synthetic scaffold-based (biodegradable) valve replacements in rodent models has not been achieved to date...

The authors report a case of left ventricular perforation and cardiac tamponade in a patient undergoing endovascular aortic and mesenteric stent grafting. During the procedure, the anesthetist noticed a sudden increase in central venous pressure and a decrease in blood pressure. Cardiac tamponade was suspected and confirmed by transesophageal echocardiography. Pericardiotomy resulted only in temporary stabilization. Emergency sternotomy revealed left ventricular perforation. Both anesthetists and radiologists have to be aware of such rare but severe complications of interventional procedures...

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...

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...
