Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...

Angiocardiography and physical findings established the diagnosis of a coronary arteriovenous aneurysm in a 6-year-old asymptomatic schoolgirl. During the 7 years that have ensued, her heart size, electrocardiogram, and general condition have remained normal. Review of the literature discloses 13 autopsy-proved coronary artery fistulas and 8 cases wherein the diagnosis was established by explor...

1. Anomalies of origination and course • Absent left main trunk, • Anomalous location of coronary ostium within aortic root or near proper aortic sinus of Valsalva (for each artery) • Anomalous location of coronary ostium outside normal "coronary" aortic sinuses • Anomalous location of coronary ostium at improper sinus (which may involve joint origination or "single" coronary pattern) • Single ...

SEVERAL excellent reviews have been published recently describing the anatomic and clinical findings in patients with congenital coronary arteriovenous fistulas or with communications between the coronary arteries and the cardiac chambers.1-3 The recognition of this clinical entity presents real difficulty, since it may easily be confused with other lesions causing a continuous or to-and-fro mu...

The incidence of multiple fistulas within all coronary arteriovenous fistulas varies between 10.7% and 16%. Double coronary-arteriovenous fistulas originating from a coronary artery are much less common. In this study, we present a double fistula originating from left anterior descending coronary artery and communicating with main pulmonary artery. A 72-year-old female patient was admitted to o...

Coronary arteriovenous fistula is a rare entity and is mostly diagnosed and corrected in early childhood. We report the case of a 59-year-old female patient who was presented with chest pain during exertion for 3 months because of an aneurysmatic circumflex artery and coronary sinus fistula. We successfully ligated the circumflex artery close to the main stem and to the coronary sinus. The firs...

A 27-year-old man with bacterial endocarditis of the mitral valve and embolic episodes was bound to have a large right coronary artery fistula communicating with the left ventricle, immediately inferior to the posterior mitral annulus. The perforation of the posterior leaflet and coronary arteriovenous fistula was identified using two-dimensional Doppler echocardiography. The diagnosis was conf...

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...
