Cystic artery pseudoaneurysm after laparoscopic cholecystectomy presenting as haemobilia: a case report.

ABSTRACT

Cystic artery pseudoaneurysm which developed following a cholecystectomy and resulting in upper gastrointestinal bleeding is a rare entity, with only three cases described in the literature. We report the case of a 26-year old man who presented with upper gastrointestinal bleeding approximately three months after laparoscopic cholecystectomy. Emergency abdominal angiogram revealed a cystic artery stump pseudoaneurysm, with no evidence of active contrast extravasation. The pseudoaneurysm was coil embolised and the patient had no further bleeding episodes. In this situation an angiogram and embolisation rather than surgery is the preferred mode of management both in terms of diagnosis and treatment. The presence of a dilated cystic artery stump on angiogram following cholecystectomy is an "ominous sign", even in the absence of active extravasation of contrast.
