Abstract

A pseudoaneurysm of the cystic artery is a rare complication of cholecystitis, and is manifested by hemobilia or hematemesis. An early diagnosis is required for the successful treatment by cholecystectomy and ligation of the cystic artery. Herein, we report a case of a pseudoaneurysm of the cystic artery diagnosed by color Doppler ultrasonography and CT, and successfully treated by transcatheter arterial embolization with N-butyl cyanoacrylate in a high-risk surgical patient.

  Fig. 1 A 79-year-old male with epigastric pain. A. Color Doppler ultrasonography shows anechoic nodule with flow signal (arrow) in the gallbladder. B. Contrast enhanced CT scan reveals a small enhancing lesion in the gallbladder (arrow) and cholecystocolonic fistula (arrowhead). C. Cystic artery angiography shows a pseudoaneurysm. D. Completion angiography after glue embolization demonstrates complete exclusion of pseudoaneurysm with patent right hepatic artery.
