Traumatic Pseudoaneurysm of Superior Rectal Artery - an Unusual Cause of Massive Lower Gastrointestinal Bleed: A Case Report.

Traumatic pseudoaneurysm of superior rectal artery is an unusual cause of massive lower gastrointestinal bleed. We are reporting the first case as we could not come across any similar report in the literature. Patient underwent exploratory laparotomy, diversion sigmoid loop colostomy, perineal wound debridement and antiseptic dressing for traumatic perineal wound. Patient had repeated episode of massive lower gastrointestinal bleeding and was diagnosed as a case of bleeding from superior rectal artery pseudoaneurysm which was managed by selective superior rectal artery embolization after failure of surgical treatment.
