This clinical study was performed to investigate the patency rate of endothelial cell-seeded small-diameter expanded polytetrafluoroethylene grafts during coronary artery bypass surgery. Between September 1995 and December 1998, 14 patients (median age: 71 years, range: 61-79 years) received 21 endothelial cell-seeded small-diameter grafts. In all, 43% of the performed implantations were reoper...

Dysfunction of the arteriovenous fistula for hemodialysis is a challenge nephrologist and vascular surgeon. Although experience limited, use forearm basilic vein as outflow radiocephalic has been considered. We report case 60-year-old male, with cardiovascular comorbidities history ischemic complications induced by access. Drainage problems were present in was used access repair. The procedure ...

OBJECTIVES We sought to examine, angiographically, the longterm fate of a large number of mainly venous coronary bypass grafts and to correlate graft patency and disease with patient survival and reoperation. BACKGROUND Much is known about bypass graft patency and disease, but the precise relation between graft fate and patient outcome has not been substantiated and documented. METHODS A to...

In a model of early and aggressive vein graft stenosis in pigs, an intervention was performed with a single stent (n = 12 grafts), multiple stents (n = 6), or balloon angioplasty (n = 6), while grafts with mild stenoses were left untreated (n = 8). Four weeks after intervention, angiography showed that grafts with single stents, balloon angioplasty, or untreated grafts had patency rates of 92%,...

http://www.journal-imab-bg.org / J of IMAB. 2013, vol. 19, issue 1 / ABSTRACT: Objective: To analyze the one-year-patency of infrainguinal arterial reconstructions in relation to venous graft diameter and length . Material and Methods: 56 patent and failed infrainguinal autovenous by-pass reconstructions were followed up for no less than a year. The diameter of the vein was measured at the site...

Homologous vein grafts are becoming increasingly useful in patients without suitable autologous saphenous veins for peripheral arterial bypass procedures [4, 81. However, fresh veins are the only tissue that has been used successfully in homograft vascular reconstruction in terms of long-term patency [4]. The advantages of a reliable method of long-term storage of viable vein segments and the u...

The small saphenous vein (SSV) is an important graft in limb salvage surgery. It is frequently translocated for bypass surgery. Sometimes, the use of the SSV as an in-situ graft for posterior tibial artery or peroneal artery reconstruction offers the advantages of reduced vein graft injury and improved patency. Recently, saphenous vein mapping through computed tomography (CT) volume rendering t...

Paget-Schroetter Syndrome is a primary, effort vein thrombosis of the axillo-subclavian level. It occurs predominantly after repetitive sport movements in the dominant limb in young healthy male individuals. Patients refer with pain, swelling and blue discolouration in the affected upper extremity. We present a 33-years-old woman with primary thrombosis of left subclavian vein, with no history ...

BACKGROUND Radial artery (RA) aortocoronary bypass grafts anastomosed to a branch of the circumflex coronary artery have significantly better patency rates than saphenous vein (SV) grafts at 5 years, but the physiological characteristics and mechanisms involved are not clearly defined. We compared RA and SV graft vasomotor and flow responses to endothelium-dependent and -independent stimuli 5 y...

Introduction: Acknowledging the superior long term patency of infrainguinal saphenous bypass to distal popliteal artery, debate continues regarding the choice of alternative conduits and possible surgical adjuncts to improve infl ow and graft salvage. The objective of this retrospective study was to determine the effectiveness of proximal anastomotic patch as adjunct to open surgical below the ...
