title: Ectopic varices in portal hypertension: computed tomographic angiography instead of repeated endoscopies for diagnosis.
abstract: Ectopic varices (EcV) accounting for 1-5% of all varices in portal hypertension are composed of dilated portosystemic collaterals located in unusual sites instead of the most known gastroesophageal region. The difficulty in localization of bleeding is a great burden on the management of these patients. Herein, we present patients with EcV as well as with portal hypertension and recurrent intestinal bleeding. The sites of EcV were identified with computed tomographic angiography, after a series of inconclusive endoscopies, and moreover a selective celiac arteriographic examination of one of the patients.
