BACKGROUND The surgically created arteriovenous fistula has recently been recommended as the best available angioaccess for hemodialysis. Therefore, in this study, we carried out a clinical analysis on surgical procedures in the ligation and division of a distal vein to achieve similar effects as those of vein end-to-arterial side after side-to-side anastomosis. METHODS We retrospectively rev...

Abtract: Recently, a new proximal anastomosis device of a saphenous vein graft (SVG) to the aorta, the PAS-Port device (Cardica, Redwood City, Calif) has been introduced and yielded encouraging results in terms of neurologic complications and early patency.1,2 However, there is a concern about the midterm (at least 1 year after surgical intervention) patency rate. The aim of this study was to e...

background and objectives: there are different types of vascular access. we compared the patency rate for six months in ulnar-basilic fistula and radio-cephalic fistula for vascular access in hemodialysis patients.   methods: the study was performed on 60 patients of 50.6±13.5 years of age with end-stage renal failure undergoing hemodialysis from 2012-2014 in imam ali hospital in zahedan. patie...

Despite the very important use of arterial bypass conduits, vein grafts remain one cornerstone in coronary surgery. Newer studies show a saphenous vein graft patency of about 60% at 10 years postoperatively. This article reviews the in vivo (animal) models of vein graft disease. According to the different models, the findings on pathology of graft thrombosis, neointimal hyperplasia, and vein gr...

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 a...

BACKGROUND Optimization of the saphenous vein for myocardial revascularization. OBJECTIVE To present the no-touch technique of the saphenous vein preparation. This technique consists of harvesting the vein with a pedicle of surrounding tissue, which protects the vein from spasms, obviating the need for distension. METHODS A prospective, randomized study with 156 patients who underwent arter...

OBJECTIVE The right internal thoracic artery is being used infrequently despite favorable observational angiographic data. Conversely, the radial artery utilization has increased with only limited data available. The purpose of this paper is to re-evaluate the roles of the right internal thoracic artery and the radial artery grafts. METHODS We reviewed all ischemia-directed coronary angiograp...

PURPOSE Symptomatic central vein stenosis commonly occurs when cardiac rhythm management device (CRMD) leads are placed via the subclavian vein ipsilateral to arteriovenous (AV) hemodialysis (HD) access. The purposes of this study were to determine the outcomes, complications, and patency following stenting of CRMD lead-associated central vein stenosis or occlusion, and to determine the effect ...

OBJECTIVES In middle hepatic vein dominant livers, the anterior segment of the right lobe of the liver (segments V and VIII) drains mainly into the middle hepatic vein. In these donors, when right lobe grafts are procured without the middle hepatic vein, the graft may harbor large segment V and/or VIII veins that need reconstruction to avoid graft congestion and subsequent graft dysfunction.
