Coronary arteriovenous fistula (CAVF) is a rare condition defined as an anomalous termination of the coronary arteries. The etiology of CAVF is either congenital or acquired, and iatrogenic CAVF is most commonly caused by cardiovascular surgery or percutaneous intervention. Most of the prenatally diagnosed CAVFs were related to complex heart disease, and only few cases of an isolated CAVF have ...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

BACKGROUND Oroantral fistulas are pathologic connections between the oral cavity and the maxillary sinus. Arteriovenous fistulas are abnormal connections between an artery and a vein with no intervening capillary network. METHODS We present an extremely rare case of barotrauma-related oroantral fistula with an associated arteriovenous fistula between the internal maxillary artery and the opht...

A 61-year-old man with acute myocardial infarction developed a painful hematoma in his groin after percutaneous coronary intervention. Ultrasonography, including color Doppler, detected a pulsatile, hypoechogenic, single compartment lesion (2.3 3.0 2.9 cm) consistent with a partially thrombosed pseudoaneurysm originating from the distal part of the common femoral artery (Figure, A). Sampling fr...

in order to create an effective arteriovenous fistula (avf) in patients with sustained chronic renal failure (crf), surgeons need to become familiar with various anatomical variations of venous structures in the operating field. because of variety and different types of cubital venous anatomies, there is more than a 90% possibility of creating suitable avfs in the cubital fossa , but in the wri...

introduction: a traumatic arteriovenous fistula (avf) after repetitive blunt trauma has not been described previously. in a 34-year-old male, the first reported case of such an injury after repetitive blunt trauma is described. case presentation: a 34-year-old gentleman presented with a non-healing ulcer near his medial malleolus. a bone scan was performed and then treated for presumed osteomye...

Cannulation of arteriovenous fistulae is technically more challenging than cannulation of arteriovenous grafts. With the advent of the National Vascular Improvement Initiative, Fistula First, the United States has seen an increase in the number of arteriovenous fistulae. The problem we now face is how to refocus and reeducate nurses to the intricacies of arteriovenous fistula cannulation. Throu...

Dural arteriovenous fistula of the cavernous sinus is usually a benign disease and rarely has brainstem edema as its complication. We present a patient with dural arteriovenous fistula of the cavernous sinus and brainstem edema. The brainstem edema resolved after embolization. Embolization should be considered first whenever brainstem edema occurs, progressive visual deterioration or increased ...

BACKGROUND Fistula thrombosis in patients on maintenance hemodialysis is an important morbidity factor. Arterial or venous thrombotic events have been described as complications in patients on regular hemodialysis. This study was designed to evaluate the risk factors for arteriovenous fistula thrombosis. METHODS One hundred and seventy-one patients with arteriovenous fistula on maintenance he...
