Background and Aim: Meso rex bypass is the surgical intervention of choice for children with EHPVO. Patency vein a pre-requisite this surgery however conventional diagnostic modalities like USG CT cannot accurately detect patency. Transjugular wedged hepatic portography (WHVP) detects patency Rex almost 90% accuracy. We aimed to assess in Indian EHPVO using transjugular WHVP, study portal venou...

BACKGROUND Meso-Rex bypass (MRB) surgery is being increasingly used to treat chronic prehepatic portal hypertension secondary to extrahepatic portal vein thrombosis (EPVT) and cavernous transformation (EPVCT) in children. Rather than using the internal jugular vein (IJV, the traditional venous graft), we used an autogenous splenic vein segment graft for MRB. MATERIAL/METHODS We examined 25 ch...

BACKGROUND The optimal conduit of second choice in surgical coronary revascularization remains a matter of debate. Radial artery grafts are believed to have a better patency rate than the saphenous vein grafts, although no conclusive results have been reported. This report describes the late result of a coronary revascularization with sequential venous bypass performed 30 years earlier. METHO...

OBJECTIVE This study explored the long-term outcomes of arteriovenous fistulas treated with vonapanitase (recombinant human elastase) at the time of surgical creation. METHODS This was a randomized, double-blind, placebo-controlled trial of 151 patients undergoing radiocephalic or brachiocephalic arteriovenous fistula creation who were randomized equally to placebo, vonapanitase 10 μg, or von...

OBJECTIVE The durability of cryopreserved allograft has been previously demonstrated in the setting of infection. The objective of this study was to examine the safety, efficacy, patency, and cost per day of graft patency associated with using cryopreserved allograft (vein and artery) for hemodialysis access in patients with no autogenous tissue for native fistula creation and with arteriovenou...

BACKGROUND The purpose of this study was to assess the benefits of duplex compared with clinical vein graft surveillance in terms of amputation rates, quality of life, and healthcare costs in patients after femoropopliteal and femorocrural vein bypass grafts. METHODS AND RESULTS This was a multicenter, prospective, randomized, controlled trial. A total of 594 patients with a patent vein graft...

OBJECTIVE This study was conducted to evaluate stent compression in iliac vein compression syndrome (IVCS) and to identify its association with stent patency. MATERIALS AND METHODS Between May 2005 and June 2014, after stent placement for the treatment of IVCS with acute ilio-femoral deep vein thrombosis, follow-up CT venography was performed in 48 patients (35 women, 13 men; age range 23-87 ...

OBJECTIVE It has been reported that a failed endovascular intervention adversely affects results of lower extremity bypass (LEB). We reviewed rates of prior endovascular intervention (PEI) in patients undergoing LEB with autologous vein for critical limb ischemia (CLI) to determine effects on graft patency, limb salvage, and amputation-free survival. METHODS Retrospective review was conducted...

Twenty-three coronary bypass graft patients were evaluated by a contrast-enhanced computed tomography (CT) technique to determine graft patency. Four to six 4.8-second sequenced scans with a 1second interscan interval were obtained in each patient during the hand injection of 25-30 ml of contrast medium in a peripheral vein. Patency of grafts was determined by a characteristic contrast enhancem...

Blood flow and patency rates obtained by lingual to basilar artery anastomosis were compared with those obtained by saphenous vein bypass graft from the carotid to the basilar artey in two groups of ten dogs. Flow was measured by an electromagnetic technique while blood pressure and blood gases were monitored. Graft patency also was determined by angiography and histological examination. The ar...
