Abstract:
Hepaticartery pseudoaneurysms are a rare complication of chronic pancreatitis. However, giant pseudoaneurysms (80 mm) and complicated biliary obstructions are extremely rare. This article reports a 75 year-old man with chronic pancreatitis that presented as upper abdominal pain and obstructive jaundice. Computed tomography revealed a hepatic artery pseudoaneurysm measuring 80 × 72 × 70 mm. We performed aneurysm resection and common hepatic artery bypass, using a great saphenous vein graft in the patient. The postoperative course was uneventful, and he was discharged on the 10th postoperative day. However, on the 135th postoperative day, he died of massive hemorrhage into the peritoneal cavity.
