we report a case of a 40 year old man with portal hypertension caused by a splenic arteriovenous fistula that was diagnosed at laparotomy. he presented with bleeding esophageal varices and was initially treated by sclerotherapy. at laparotomy, portal pressure was 40 cmh20 but fell to 20 cm h20 after the fistula was treated with splenectomy. all symptoms disappeared shortly after operation and t...

BACKGROUND Native arteriovenous fistula is one of the important routes for hemodialysis patients because of increased long-term survival and preservation of quality of life. We reported on a single-center experience with using pharmacomechanical thrombolysis for the treatment of thrombosed native arteriovenous fistula. MATERIAL/METHODS This was a retrospective study of 12 hemodialysis patient...

A progressive rise in the number of patients accepted for renal replacement therapy has been reported world wide [1]. Permanent vascular access (VA) is the life-line for the majority of these patients, when hemodialysis is the treatment of choice. Thus, the successful creation of permanent vascular access and the appropriate management to decrease the complications is mandatory. A well function...

The efficiency of haemodialysis treatment relies on a functional status of vascular access. A vascular access makes life-saving haemodialysis treatments possible. The efficiency of haemodialysis treatment relies on a functional status of vascular access. The purpose of this review was to discuss the role of haemodialysis and vascular access in end stage kidney disease. Vascular access and its r...

Native arteriovenous (AV) fistula which was introduced into clinical practice in 1966 by Brescia, Cimino, Appel and Hurowich [1] is still a vascular access of choice for chronic hemodialysis patients. The main advantages were longevity and fewer, especially infectious, complications. For the patients with exhausted vasculature, AV grafts made of expanded polytetrafluoroethylene (ePTFE), introdu...

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. ...
