Splenic artery pseudoaneurysm rupture post-laparoscopic sleeve gastrectomy.

Abstract

A splenic artery pseudoaneurysm (SAP) is a rare vascular entity that is becoming increasingly recognized as a potential complication of bariatric surgery. This is a case of a 36-year-old woman brought by ambulance to a regional emergency department with abdominal pain, collapse, and gross haemodynamic instability 2 years post-laparoscopic sleeve gastrectomy. She received aggressive resuscitation in the emergency department but could not be stabilized and so underwent an emergency laparotomy. Intra-operatively, she was found to have a ruptured SAP with active bleeding, which was managed with a splenectomy. A high index of suspicion is required in any patient presenting with abdominal pain and circulatory collapse in the context of previous bariatric surgery. In rural or regional settings without immediate access to interventional radiology services, the most appropriate management option will almost invariably be an emergency laparotomy and splenectomy due to the risk of deterioration during patient transfer.
