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 1-second 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 enhance...

Peripheral Arterial Disease (PAD) in diabetic patients is a significant cause of Morbility. Long arterial occlusion patient previously treated can require unusual and complex solution. Herein we report case complicated bypass with history for bilateral popliteal aneurysm. A 51-year-old male, smoker, hypertension diabetes mellitus was referred to our hospital rest pain left limb peripheral cyano...

OBJECTIVES The long-term patency rates for individual and sequential saphenous vein grafts (SVG) as coronary bypass conduits are angiographically compared; the impact of native coronary vessel characteristics is investigated. METHODS A total of 875 distal coronary anastomoses on 500 SVGs were assessed in 430 patients at an average of 5.8+/-3 years after a coronary revascularization procedure....

AIM Micro-vascular anastomosis is a difficult art. It can be learnt and perfected only by practice using vessels of small animals in the laboratory. The purpose of the study was to practice various anastomotic techniques using rat femoral vessels and study the patency rates. MATERIAL AND METHODS Sixty-four Sprague-Dawley rats were used in the study. The following procedures were conducted on ...

BACKGROUND The endoscopic vein harvesting (EVH) method has been used in coronary artery bypass surgery in many countries. We started using the EVH method recently, and investigated the results during the early learning period. METHODS Between March 2012 and June 2014, 75 patients (31 patients in the EVH method group, and 44 patients in the open method group) who underwent isolated first-time ...

Mats Dreifaldt (2013): Conduits in coronary artery bypass grafting surgery: Saphenous vein, radial and internal thoracic arteries. Örebro Studies in Medicine 93. A novel technique for saphenous vein (SV) graft harvesting, the No-touch technique (NT), has been developed at the Dept. of Cardiovascular surgery, Örebro University hospital. With NT the SV is harvested with a pedicle of surrounding t...

BACKGROUND Vein bypass surgery is an effective therapy for atherosclerotic occlusive disease in the coronary and peripheral circulations; however, long-term results are limited by progressive attrition of graft patency. Failure of vein bypass grafts in patients with critical limb ischemia results in morbidity, limb loss, and additional resource use. Although technical factors are known to be cr...

BACKGROUND Transjugular intrahepatic portosystemic shunt (TIPS) has become an important and effective interventional procedure in treatment of the complications related to portal hypertension. Although the primary patency of TIPS has been greatly improved due to the clinical application of cover stent-grafts, the long-term patency is still suboptimal. This study was to investigate the feasibili...

BACKGROUND The purpose of this study was to evaluate the use of a Fogarty arterial embolectomy catheter (Fogarty catheter) in intraoperative balloon angioplasty of the cephalic vein, in order to determine its effect on the patency of arteriovenous fistulas (AVFs) created for hemodialysis access. METHODS A total of 156 patients who underwent creation of an AVF were divided into two groups, bas...

For over a decade there has been accumulating evidence that the use of more than a single arterial graft during coronary artery bypass grafting can improve clinical outcomes. However the vast majority of patients in most developed countries still only receive a single arterial conduit even in the presence of multivessel coronary artery disease. This review summarizes the current evidence for th...
