Abstract
A 73-year-old man underwent a pylorus-preserving Whipple's procedure for distal cholangiocarcinoma. His postoperative course was complicated by the formation of a pancreatic fistula, which was initially managed conservatively. On postoperative day (POD) 86, he lost 100 ml of blood from the site of the pancreatic fistula. Contrast-enhanced computed tomography (CT) showed a pseudoaneurysm, 12 mm in diameter, in the common hepatic artery. The diameter of the pseudoaneurysm increased to 15 mm on POD 89, so we implanted coronary covered stents to prevent massive bleeding from rupture and to retain hepatic arterial flow. Six days after implantation, computed tomography findings confirmed a thrombosed pseudoaneurysm as well as patent hepatic arterial flow. Follow-up CT 18 months after surgery showed patent hepatic arterial flow. There have been no signs of rebleeding or abnormal liver function.
