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 ...

BACKGROUND Percutaneous renal biopsy is a valuable procedure in the management of and prognostication for patients with renal disease. Complications, although rare, occur with renal biopsies. Arteriovenous fistulas and heavy bleeding are notable complications. In this report, we describe simple suturing of the biopsy tract for salvage of a graft destined for a nephrectomy due to a profusely ble...

Surgery In 1966, Brescia, Cimino and colleagues described the surgical creation of an arteriovenous fistula. Access Arteriovenous fistulae. A great variety of surgical techsurgery developed remarkably over the next decade niques and tricks are available to manage arteriovenous introducing various types and sites of anastomoses and fistula(e) complications like stenosis, thrombosis, and learning...

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...
