Abstract:
Cystic artery pseudoaneurysm (CAP) is a rare disease, with small number of previous reports related to CAP. Besides, it is frequently prone to critical condition due to arterial bleeding. Here, we presented a case of ruptured CAP with acute calculus cholecystitis and its subsequent successful management with temporary endoscopic biliary drainage for obstructive jaundice and embolization for the culprit artery without cholecystectomy. Since CAP is at high risk of bleeding, intravascular treatment, which is only one currently available therapeutic option, is urgently required in the clinical sites.
