BACKGROUND AND OBJECTIVES The role of thrombophilia in failing arteriovenous fistula (AVF) among patients with ESRD undergoing hemodialysis is not established. This study aimed to assess whether AVF primary patency is associated with thrombophilia and coagulation abnormalities. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This observational study screened 219 patients between 2002 and 2004 f...

INTRODUCTION A well-functioning arteriovenous fistula (AVF) is the best modality for vascular access in patients with end-stage renal disease (ESRD) requiring haemodialysis (HD). However, AVFs' main disadvantage is the high rate of maturation failure, with approximately one third (20%-50%) not maturing into useful access. This review examine the use of Far-Infra Red therapy in an attempt to enh...

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...

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 ...

Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...

Capsule endoscope aspiration into the respiratory tract is a rare complication of capsule endoscopy. Despite the potential seriousness of this complication, no accepted methods exist to accurately predict and therefore prevent it. We describe the case of an 85-year-old male who presented for evaluation of iron deficiency anemia. He complained of dysphagia while ingesting a patency capsule, with...

Aims The purpose of this study was to validate ST segment resolution as a non-invasive marker for patency of the infarct-related artery 90 min after the start of streptokinase therapy in patients with acute myocardial infarction. Methods and Results In the HIT-4 angiographic substudy, 447 patients with acute myocardial infarction </=6 h received 1.5 million IU streptokinase. Angiograms of the i...

BACKGROUND The aim of the present study was to assess the long-term graft patency rate of the radial artery (RA), in comparison to the saphenous vein (SV) in patients harvested for both vessels. METHODS AND RESULTS RA and SV were concomitantly used for coronary artery bypass grafting in 318 patients in an 8-year period from January 2002 to March 2010. During follow-up, graft patency was asses...

Introduction: In keeping with established international guidelines our institute follows an “all-autogenous” approach with regard to hemodialysis access. Upper arm transposition fistulas can allow for access options when forearm autogenous options are not suitable. We evaluate our experience with a single staged brachio-basilic arteriovenous fistulas (BBAVF) to assess efficacy and patency. Meth...
