A case of massive lower gastrointestinal bleeding: Superior rectal artery pseudoaneurysm

摘要

Dear Editor,While most cases of acute lower gastrointestinal (GI) bleeding resolve spontaneously following supportive management, 10% to 15% of patients in whom bleeding persists require further diagnostic and therapeutic intervention.The most common causes of massive lower GI bleeding are diverticular disease and angiodysplasia. Massive lower GI bleeding resulting from a pseudoaneurysm is less common, but is an important consideration following arecent procedural or surgical intervention. Here we report a rare case of acute massive lower GI bleeding resulting from an iatrogenic traumatic superior rectal arterypseudoaneurysm.
