BACKGROUND The provision and maintenance of vascular access remains a major cost to end stage renal failure programmes. There are few reports regarding the surgical revision of the failing native elbow arteriovenous fistula (AVF). PATIENTS AND METHODS A retrospective case note review was performed on all patients identified from the hospital vascular access database as having undergone constr...

The purpose of this study was to evaluate the diagnostic capability of imaging modalities used for preoperative mesenteric-left portal bypass ("Rex shunt") planning. Twenty patients with extrahepatic portal vein thrombosis underwent 57 preoperative planning abdominal imaging studies. Two readers retrospectively reviewed these studies for an ability to confidently determine left portal vein (PV)...

BACKGROUND Witholding treatment in asymptomatic/pauci-symptomatic high-grade central vein stenosis (CVS), i.e. those not causing debilitating painful extremity oedema, the benefits of which have been shown in only one study in grafts, is debatable. The aim of our study was to assess the short- and long-term benefits of such a strategy in mainly autogenous fistulas. METHODS We retrospectively ...

PURPOSE The superiority of autogenous vein conduits is well known in lower extremity arterial bypass (LEAB). Among various alternative conduits for LEAB, long-term results of arm vein grafts were investigated in this study. MATERIALS AND METHODS We retrospectively reviewed clinical characteristics of 28 patients who underwent infrainguinal LEAB with autogenous arm vein grafts at a single inst...

Various alternative conduits for aortocoronary bypass grafting have been suggested when the saphenous vein quality is inadequate. During a 10-year period we have used the cephalic vein in 39 patients. Eighteen entered an angiographic follow-up study. A total of 31 arm vein grafts were used with 43 distal anastomoses. When calculating patency by number of patent distal anastomoses, this was 46% ...

PURPOSE To analyze the long-term results of above-the-knee femoro-popliteal bypass (ATKFPB) with vein grafts compared with polytetrafluoroethylene (PTFE) grafts. METHODS A database of patients with chronic atherosclerotic occlusive disease who underwent ATKFPB was retrospectively reviewed. Characteristics of patient and arterial lesion, and follow-up results were compared between vein grafts ...

OBJECTIVE Left internal thoracic artery (LITA) grafting has become the gold standard in coronary artery bypass graft procedure (CABG). In order to optimize the use of LITA or other grats, sequential anastomosis has been used. There is no consensus on equivalence of results between isolated and sequential grafts. The aim of this study is to compare the patency of isolated versus sequential graft...

BACKGROUND The long-term success of coronary bypass surgery is dependent on graft patency after surgery. This trial was designed to determine if aspirin improved saphenous vein graft or internal mammary artery (IMA) graft patency between 1 and 3 years after coronary artery bypass grafting (CABG). METHODS AND RESULTS After receiving aspirin 325 mg/d for 1 year after CABG and undergoing a 1-yea...

PURPOSE Various alternative conduits have been used for lower extremity revascularization when an adequate ipsilateral greater saphenous vein is absent. This study compared the effectiveness of all-autogenous multisegment arm vein bypass grafts with that of composite grafts composed of combined prosthetic and autogenous conduits. METHODS One hundred fifty-three lower extremity revascularizati...

BACKGROUND Fibrinogen is related to the pathogenesis of atherosclerosis. The inflammatory process in atherosclerosis may cause an increase in plasma fibrinogen level. Therefore, in this study we proposed to investigate whether plasma fibrinogen is associated with the patency of saphenous vein graft in patients at least 1 year after coronary artery bypass graft (CABG) surgery. METHODS Patients...
