Congenital pulmonary arteriovenous fistulae, provided that they are not present in very large numbers, are best managed surgically, and there is no effective alternative management. Where pulmonary arteriovenous fistulae develop as a consequence of pulmonary hypertension it is rational to resect the fistulae if the cause of pulmonary hypertension - for example, mitral stenosis - is correctable....

Definitive clinical diagnosis of congenital pulmonary arteriovenous fistula is extremely difficult. In order to evaluate the diagnostic value of echocardiography, 2 cases with suspected pulmonary arteriovenous fistula were studied. In the first case, there was a solitary pulmonary arteriovenous fistula, while in the second multiple minute pulmonary arteriovenous fistulas were illustrated. The s...

common autosomal-dominant genetic disorders with an incidence of approximately 1:3,500. Vascular abnormalities associated with NF-1 include stenotic or occlusive diseases, aneurysms, arteriovenous malformations and, rarely, arteriovenous fistula (AVF). Association of arteriovenous fistula with NF-1 is rare with a few cases of vertebral AVF having been reported (1-3). Endovascular occlusion of t...

the possibility of abnormal avf was considered and it was confirmed on contrast-enhanced computed tomography (ct), inferring that this modality is not only fast and non-invasive, but also accurate in detecting vascular abnormalities. herein, we report a 42-year-old woman with congenital avf between the external carotid artery and external jugular vein, presenting with palpitation and dyspnea. t...

 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...

We report two rare and infrequent cases, one of a patient with Cognard type V tentorial dural fistula diagnosed at the beginning as trunk glioma in gait disturbance. And another Guillian Barré syndrome tetraparesis secondary to arteriovenous fistula.

A 69-year-old woman with hypertension was admitted for an acute coronary syndrome. Emergency coronary angiography showed a long, bifurcated, calcified lesion in the left anterior descending artery (LAD). An interventional procedure was performed by predilations with an expandable and a nonexpandable balloon. Following the last inflation, angiography showed LAD occlusion due to a perforation, wh...

in this paper, we describe a case of an aneurysmal circumflex artery connected to the coronary sinus through a fistula in a 40-year-old man with a two-year history of palpitation and chest pain. we discussed surgical management for patients with coronary artery fistula (caf), particularly for asymptomatic patients with a small left-to-right shunt .
