PURPOSE To study the arteriovenous fistula patency, duration of its maintenance, and its relative complications. MATERIALS AND METHODS One hundred and thirty patients who had undergone hemodialysis during five years (1996 to 2001) were included in this study. The patency rate and complications, including paresthesia, pain induced by ischemia, venous hypertension, infection, erythema, and edem...

BACKGROUND Dialysis vascular access complications are considered as significant causes of morbidity in chronic hemodialysis patients. OBJECTIVES The aim of the present study was a comparison of axillary loop and straight grafts patency and its complications in hemodialysis access. PATIENTS AND METHODS In this cohort study conducted at Shahid Beheshti Medical University, 77 patients who unde...

OBJECTIVE The use of self-expanding stent grafts for treatment of popliteal artery aneurysms (PAA) is a matter of debate, although several studies have shown similar results compared with open surgery. In recent years, a new generation stent graft, with heparin-bonding technology, became available. The aim of this study is to present the results of endovascular PAA repair with heparin-bonded st...

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 ...

To determine the clinical profile and efficacy of accelerated recombinant tissue-type plasminogen activator (rt-PA) dose regimens, five different strategies of thrombolytic therapy in a total of 232 patients were systematically evaluated in the setting of acute myocardial infarction. The fifth strategy involved a combination of accelerated rt-PA and intravenous urokinase (regimen E). A weight-a...

In an attempt to analyse the results of saphenous bypass grafting 213 patients were re-investigated by repeat coronary, graft and left ventricular angiography. In this series, the presence of diffuse arterial disease was not considered as a contra-indication to operation. Instead, additional endarterectomy was performed. The overall patency rate was 88% and was not significantly altered by the ...

OBJECTIVE We wanted to retrospectively evaluate the long-term therapeutic results of iliac arterial stent placement that was done in a single institution for 10 years. MATERIALS AND METHODS From May 1994 to April 2004, 206 patients who underwent iliac arterial stent placement (mean age; 64+/-8.8) were followed up for evaluating the long term stent patency. Combined or subsequent bypass surger...

Childhood inguinal herniorrhaphy is one common cause of seminal tract obstruction. Vasovasostomy (VV) can reconstruct seminal deferens and result in appearance of sperm and natural pregnancy in some patients. Secondary epididymal obstruction caused by a relatively long-term vasal obstruction is a common cause of lower patency compared with VV due to vasectomy in adults. From July 2007 to June 2...

The aim of this study was to evaluate the outcomes of multiple advanced surgical treatments (i.e. microsurgery, laparoscopic surgery and endoscopic surgery) for acquired obstructive azoospermia. We analyzed the surgical outcomes of 51 patients with suspected acquired obstructive azoospermia consecutively who enrolled at our center between January 2009 and May 2013. Modified vasoepididymostomy, ...

The major goal of reperfusion strategies in patients with acute myocardial infarction is to achieve patency of the infarct-related artery . Improvement in ventricular function and survival are related to initial and continued potency of this artery . The greater initial patency of the infarct-related artery after intravenous recombinant tissue-type plasminogen activator (r(-PA) compared with th...
