Abstract
A 66-year-old woman was admitted to our department with abdominal distension. Further examination revealed a tumor in the groove area that was diagnosed as groove pancreatic carcinoma. Preoperative multidetector-row CT (MDCT) showed Type VI Adachi hepatic arterial anomaly, in which the common hepatic artery arises from the superior mesenteric artery behind the portal vein. Pancreaticoduodenectomy was performed without injury to the portal vein or common hepatic artery during the dissection of the No 8a lymph node and the lymph node around the superior mesenteric artery. Histopathological examination revealed a tubular adenocarcinoma in the pancreas head, which involved the groove and duodenal wall. In groove pancreatic carcinoma treatment, MDCT is useful for both diagnosing and understanding vascular anomalies to avoid intraoperative complications.
