Angiography as an aid in extra-enteric gastrointestinal bleeding due to visceral artery aneurysm.

Three unusual patients with visceral artery aneurysms involving the hepatic artery, inferior pancreaticoduodenal artery, and a mesenteric branch artery are presented. Each of these lesions is unusual and all were diagnosed preoperatively. Surgical intervention was planned on the basis of angiography. In two patients with hypovolemia a simple diagnostic approach employing emergency selective angiography was formulated and successfully used.
