abstract background: the optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. the purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a post thrombotic syndrome (pts). methods: during 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous throm...

BACKGROUND Long-term patency of extracranial-to-intracranial (EC-IC) vein bypass is poorly understood. OBJECTIVE We report our experience of patency of arterial pedicle grafts and interposition vein grafts for the purpose of EC-IC bypass. METHODS We analyzed 294 consecutive patients who underwent 178 intracranial arterial pedicle bypass procedures and 152 intracranial vein bypass procedures...

Background The saphenous vein is still the most widely used conduit in CABG surgery despite its poor long term patency. In the 1990’s a new No-touch technique for saphenous vein graft harvesting for CABG was introduced where the vein graft is harvested with a pedicle of surrounding tissue. With the No-touch technique the vein graft does not go into spasm and the vessel wall does not have to be ...

conclusion the open-cell stent is effective and its performance is higher than that obtained with the closed-cell stent for treating central vein stenosis or occlusion in hemodialysis patients. results for the open-cell stent group, 159 patients were diagnosed as central vein stenosis and 98 were occlusion. for the closed-cell stent group, 78 were stenosis and 66 were occlusion. there were two ...

BACKGROUND Graft patency is a fundamental predictor of long-term survival after coronary artery bypass surgery. Left and right internal thoracic artery (arterial) graft patency has been shown to be superior to that of saphenous vein grafts. More recently, the radial artery has been used as an aortocoronary graft, but little is known about the midterm and long-term patency of this conduit. We pe...

BACKGROUND Portal vein stenosis develops due to different causes including postoperative inflammation and oncological processes. However, limited effective therapy is available for portal vein stenosis. The objectives of this study were to evaluate the efficacy of a portal vein stent for portal vein stenosis after hepatobiliary pancreatic surgery and to determine the factors associated with ste...

The internal thoracic artery is the most effective conduit for coronary artery bypass surgery; however, most patients have multivessel disease and require additional saphenous vein or radial artery grafts. In this systematic review of the literature and meta-analysis, we aim to compare reported patency rates for these conduits and explore if differences are homogeneous across follow-up interval...

BACKGROUND In femoropopliteal bypass surgery, the use of saphenous vein grafts is preferable, but synthetic grafts are widely used above the knee. The objective of this meta-analysis was to assess the long-term patency of femoropopliteal bypass grafts classified as above-knee polytetrafluoroethylene, above-knee saphenous vein, or below-knee saphenous vein. METHODS Studies published from 1986 ...

BACKGROUND Patency and limb salvage after synthetic bypass to the arteries below-knee are inferior to that which can be achieved with autologous vein. Use of a vein collar at the distal anastomosis has been suggested to improve patency and limb salvage, a problem that is analysed in this randomised clinical study. METHODS Patients with critical limb ischaemia undergoing polytetrafluoroethylen...
