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 Long-term patency of extracranial-to-intracranial (EC-IC) vein bypass is poorly understood. OBJECTIVE We report our experience of patency of arterial pedicle grafts and interposition vein grafts for the purpose of EC-IC bypass. METHODS We analyzed 294 consecutive patients who underwent 178 intracranial arterial pedicle bypass procedures and 152 intracranial vein bypass procedures...

Although arterialovenous fistulae (AVF) is considered to be vital for chronic kidney disease (CKD) patients, but they may cause complications and problems. For instance they may fail soon after their creation. The most important cause of failure in these cases is intrafistula thrombus formation. Whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this stud...

Purpose: To investigate outcomes following treatment of thrombosed native dialysis fistulas with AngioJet thrombectomy. Materials and Methods: We retrospectively reviewed an existing database and included patients according to the following criteria: thrombosed fistula, native fistula, and use of the AngioJet system for mechanical thrombectomy. Outcomes included clinical success, complications,...

In this series we present the results of a retrospective analysis of 66 vasovasostomy procedures performed between 1983 and 1991. Obstructive intervals and serum antisperm antibodies were correlated with pregnancy and patency rates. With obstructive intervals of less than 5 years a patency rate of 100% (31/31) was obtained. Even more than 10 years after reversal, pregnancy occurred in 25% (2/8)...

BACKGROUND Advances in endovascular technology led to an alternative treatment option for TASC II D (TransAtlantic Inter-Society Consensus II class D) lesions. This study was aimed to evaluate the outcomes of endovascular treatment for TASC II D femoropopliteal lesions. METHODS Endovascular intervention with bare nitinol stent implantation was performed on 58 limbs (53 patients) with TASC II ...

OBJECTIVE To assess the use of radiofrequency myringotomy in combination with mitomycin C as an alternative myringotomy technique on rabbits. STUDY DESIGN Experimental animal research protocol. SETTING University of Crete, School of Medicine, Medical Experimental Education and Research Center. METHODS Radiofrequency myringotomies were performed under general anesthesia on both ears of 20 ...

BACKGROUND Although stent implantation is used worldwide for peripheral arterial disease, there is little data on the safety and long-term patency of stents implanted for venous disease. METHODS AND RESULTS We studied 13 patients with 14 lesions (6 males, 7 females, mean age: 63.2±10.2 years) diagnosed with venous stenosis and who underwent venous stenting. We examined the location of the ste...

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. Pat...
