title: Hepatic artery pseudoaneurysm following laparoscopic cholecystectomy.
abstract: Hepatic artery pseudoaneurysm is a rare and potentially fatal complication of laparoscopic cholecystectomy that often presents with abdominal pain, anemia, hemobilia, and liver function elevations. The authors report a case of hepatic artery pseudoaneurysm diagnosed by abdominal computed topography in a 54-year-old man who had undergone laparoscopic cholecystectomy the previous month. Definitive treatment was angiography with embolization.
