title: Splenic arteriovenous fistula causing massive ascites: a case report.
abstract: A case of splenic arteriovenous fistula leading to portal hypertension and ascites is presented. The recognition of this vascular lesion is important. When portal hypertension is secondary to a splenic arteriovenous fistula, the complications of portal hypertension can be avoided by the resection of the lesion. The diagnosis can be suspected by clinical findings and confirmed by angiographic delineation of the fistula. Surgical resection of splenic arteriovenous fistulae must include the fistula and all dilated venous tributaries to prevent thrombosis and recurrent portal hypertension.
