introduction: traumatic arteriovenous fistula (avf) called to an abnormal relationship between artery and vein which occurs in 10% of arterial traumas. if treatment of avf due to trauma delayed, different outcomes including heart failure, varices and varicose ulcers may accure. in case of chronic traumatic avf, open surgery may lead to remarkable outcomes, presence of many lateral veins and var...

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 ...

Objective The aim of this study was to describe the demographic, clinical and anatomic characteristics of coronary arteriovenous fistulas in adult patients who underwent open cardiac surgery and to review surgical management and outcomes. Methods Twenty-one adult patients (12 female, 9 male; mean age: 56.1±7.9 years) who underwent surgical treatment for coronary arteriovenous fistulas were re...

We report a case of coronary-subclavian steal syndrome, which had been masked by a malfunctioning hemodialysis access vessel and then reappeared after a successful angioplasty of multiple stenoses in the arteriovenous fistula of the left arm in a 61-year-old man. This case suggests that coronary-subclavian steal syndrome should be considered before a coronary artery bypass grafting surgery usin...

A 50 year old woman presented with a history of angina and palpitation. She had a positive exercise test and thallium scintigraphy showed reversible ischaemia in the territory of the left anterior descending coronary artery. Coronary angiography showed a small coronary arteriovenous fistula arising from the bifurcation of the left main stem--that is, the origin of the left anterior descending a...

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 In patients in chronic hemodialysis via upper extremity arteriovenous fistula in whom ipsilateral internal thoracic artery graft was used for myocardial revascularization, hemodynamic interference between the fistula and the graft during dialysis can be hypothesized. METHODS AND RESULTS In 5 patients undergoing chronic hemodialysis via upper extremity arteriovenous fistula, ipsilat...
