Cholecystitis-related cystic artery pseudoaneurysm: Case report

Asmae Rais et al. Radiol Case Rep. .

Abstract

The pseudoaneurysms of the cystic artery (CAP) are very uncommon. They usually develop as a result of an acute cholecystitis or after a cholecystectomy. Among the complications, we can find hemorrhaging, biliary blockage, and haemobilia. Limited understanding of the illness makes managing specific cases difficult. We describe a case of a cystic artery pseudoaneurysm complicating an acute cholecystitis that was successfully treated by transcatheter arterial embolization.

Keywords: Cholecystitis; Cystic artery; Interventional radiology; Pseudoaneurysm.
