Cystic Artery Hemorrhage as a Rare Complication of Acute Gangrenous Cholecystitis.

This report presents a case of cystic artery hemorrhage resulting from acute gangrenous cholecystitis. During an emergency laparoscopic cholecystectomy, the surgical team unexpectedly encountered hemorrhage from the cystic artery. Subsequent pathological examination confirmed the diagnosis of acute gangrenous cholecystitis. As a severe infectious condition of the gallbladder, acute gangrenous cholecystitis is typically associated with a high risk of complications; however, cystic artery hemorrhage, as a direct complication, is exceedingly rare. This article seeks to investigate both common and uncommon complications of acute gangrenous cholecystitis through the analysis of this case, emphasizing the clinical features, pathogenesis, and management strategies related to cystic artery hemorrhage to improve clinicians' capacity to recognize this rare occurrence.
