objectives the present study aimed to compare the efficacy rate of avfs using two different anastomosis methods; side to side (sts) versus end to side (ets) and to determine whether the different approaches render any preferences or complications. background in candidate patients for permanent hemodialysis or dialysis on a regular basis, an appropriate vascular access has great importance. the ...

Background and Objectives: Arteriovenous fistula is a popular vascular access method for surgical treatment of hemodialysis patients. The method, however, is associated with a high rate of early failure varying in the range of 20-60%. Predicting early Arteriovenous fistula failure and its risk factors can help reduce its incidence, its hospitalization rate, and associated costs. In this study, ...

purpose: to describe a complicated case of traumatic carotid-cavernous fistula (ccf) and our management strategy. case report: a 13-year-old patient was referred one month following a car accident and facial trauma with severe proptosis, chemosis and limitation of ocular movement. presence of murmur and an enlarged superior ophthalmic vein on orbital imaging suggested an arteriovenous fistula. ...

background and purpose: pain perception with arteriovenous fistula (avf) cannulation is a major concern among patients undergoing hemodialysis. this study aimed to compare the efficacy of cryotherapy and placebo in the reduction of avf puncture-related pain in hemodialysis patients. methods: this randomized clinical trial was conducted on 50 patients undergoing hemodialysis selected via random ...

background: arteriovenous fistula (avf)is the ideal method of vascular access for patients on maintenance hemodialysis (hd).therefore it is an important part of treatment in hd.there are several observations that indicate the role of inflammation in failure of avf.the aim of this study was to evaluate the hematologic and inflammatory biomarkers in early avf failure.   methods : this case-contro...

background: coronary arteriovenous fistulas (cavfs) are direct connections from one or more coronary arteries to cardiac chambers or a large vessel. they are mostly of congenital origin. the aim of this study was to describe clinical presentation and also delineate the course and management of cavf. methods: clinical data, chest x-rays, echocardiographic and angiographic evaluation of 40 patien...

BACKGROUND AND OBJECTIVES The relative merits of buttonhole (or blunt needle) versus rope ladder (or sharp needle) cannulation for hemodialysis vascular access are unclear. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Clinical outcomes by cannulation method were reviewed in 90 consecutive home hemodialysis patients. Initially, patients were trained in rope ladder cannulation. From 2004 on, a...

background: we aimed to analyze the effect of nursing strategies on patients with chronic renal failure (crf) undergoing maintenance hemodialysis (mhd) treatment by puncturing on arteriovenous fistula (avf). methods: ninety-two patients with chronic renal failure undergoing maintenance hemodialysis (mhd) between jan 2014 and jan 2015 were included in the study (all undergoing avf, dialysis for ...

Pulmonary arteriovenous fistula is a congenital and rarely acquired anomalous direct communications between pulmonary arteries and veins. Transcatheter embolization using metallic coil or detachable balloon is one of the common treatment procedure. However, recanalization after the embolization is one of the concern and its differentiation from the retrograde filling via pulmonary vein is diffi...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to loo...
