Cystic Artery Stump Pseudoaneurysm Following Laparoscopic Cholecystectomy: A Case Report.

Cystic artery stump pseudoaneurysm (CASP) is a potentially life-threatening condition that can be related to multiple etiologies, especially the iatrogenic factor owing to the increased number of hepatobiliary procedures. Most patients present with haemobilia. Here we report a successfully managed case of CASP that initially complained of right upper abdominal pain. A 38-year-old patient developed bile duct injury after laparoscopic cholecystectomy (LC) which was identified by magnetic resonance cholangiopancreatography (MRCP). Later, she developed haemobilia due to CASP which was then treated by trans-arterial embolization (TAE). CASP is a rare complication of post-LC, yet potentially life-threatening, with possible delayed complications occurring months to years after the surgery. Clinicians and radiologists should be aware of this important entity and its variable manifestations to facilitate early treatment.
