Abstract
Two cases of hepatic infarction as a postoperative complication after hepato-biliary surgery are reported. Case 1: A 62-year-old man was admitted to our hospital with cholangiocarcinoma of the portal hepatis, for which left hepatic lobecotmy coupled with resection of the portal vein was undertaken. Postoperatively, however, he had a massive hepatic infarction (Sa) and consequently died. Autopsy revealed that ligation of the right anterior hepatic artery had led to an extensive infarction of the liver, although the portal vein was patent. Case 2: A 46-year-old man was admitted with a recurrence of gastric cancer. Pancreatoduodenectomy coupled with resection of the portal vein and the hepatic artery was performed. When a retrograde transhepatic biliary drainage tube was inserted into the liver for bile drainnage, an intrahepatic vessle was injured and subsequently hepatic infarction occurred in the peripheral area supplied but this damaged vessel.
