PURPOSE Since the introduction of short vein bypass (SVB), many have reported its feasibility when long vein bypass (LVB) cannot be performed due to limited vein conduit. However, the presence of inflow-vessel disease may affect graft patency and thus require endovascular treatment prior to surgery. Our study aims to analyze the results between SVB and LVB. MATERIALS AND METHODS From 2009 to ...

BACKGROUND In severe coronary artery disease, coronary artery bypass grafting (CABG) surgery is indicated to re-establish an adequate blood supply to the ischemic myocardium. Effectiveness of CABG surgery for symptom relief and mortality decrease should therefore depend on bypass graft patency. As bypass using a left internal mammary artery (LIMA)-to-left anterior descending coronary artery (LA...

Objectives. The purpose of this analysis was to define the factors that predict 3-year graft patency. Background. The success of coronary artery bypass graft surgery (CABG) is dependent on vein graft patency after the operation. It has been well established by a series of Department of Veterans Affairs Cooperative Trials that aspirin (325 mg daily) improves saphenous vein graft patency early (7...

OBJECTIVES To investigate the variables affecting the long-term outcome of infrainguinal vein bypass grafts that have undergone postoperative surveillance. DESIGN A retrospective analysis. PATIENTS AND METHODS Details of 299 consecutive infrainguinal vein grafts performed in 275 patients from a single university hospital were collected and analysed. All grafts underwent postoperative duplex...

OBJECTIVES The purpose was to test the durability of the use of the unobstructed popliteal or tibial arteries as alternative inflow sources. MATERIALS We examined 106 such bypasses performed during a 12 year period (1981-93). The indication for surgery was limb salvage in 99.1%. Seventy-five percent of the patients were male, 78% were diabetic and the average age was 59.6 years. The inflow so...

PURPOSE The population of end-stage renal failure patients dependent on hemodialysis continues to expand with an increasing number of patients having an unsuitable cephalic vein or failed radio- and brachio-cephalic fistula. In these patients, the transposed basilic vein to brachial artery arteriovenous fistula (BaVT) provides autologous choice for hemodialysis. The results of basilic vein tran...

OBJECTIVE To find out whether intraoperative angioscopic assistance has any effect on graft outcome in patients with critical leg ischemia. MATERIAL AND METHODS One hundred one patients requiring a below-knee bypass were assigned to undergo in situ saphenous vein bypass with or without intraoperative angioscopic assistance; otherwise treated similarly including preoperative duplex vein mappin...

OBJECTIVE To determine the effects of smoking, plasma lipids, lipoproteins, apolipoproteins, and fibrinogen on the patency of saphenous vein femoropopliteal bypass grafts at one year. DESIGN Prospective study of patients with saphenous vein femoropopliteal bypass grafts entered into a multicentre trial. SETTING Surgical wards, outpatient clinics, and home visits coordinated by two tertiary ...

Background Superior patency rates for internal mammary artery (IMA) grafts compared with vein coronary bypass grafts have been demonstrated by retrospective studies. This difference may have been affected by selection bias of patients and coronary arteries for IMA grafting. Methods and Results To estimate the difference between IMA and vein grafts, we analyzed graft patency data of 912 patients...

PURPOSE Tumor invasion to the portal vein (PV) or superior mesenteric vein (SMV) can be encountered during the surgery for pancreatic cancer. Venous reconstruction is required, but the optimal surgical methods and conduits remain in controversies. METHODS From January 2007 to July 2012, 16 venous reconstructions were performed during surgery for pancreatic cancer in 14 patients. We analyzed t...
