A Case of Pancreatoduodenectomy for Pancreatic Head Cancer with Invasion to the Hepatic Artery from the Pancreatic Arcade

: This case pertained a 53-year-old man who underwent nab-PTX plus GEM therapy for BR-A pancreatic head cancer. He achieved a partial response and underwent pancreatoduodenectomy. Dynamic CT showed blockage of the original common hepatic artery branching from the celiac artery. Hepatic blood flow was maintained by a pancreatic arcade branching from the superior mesenteric artery which ran along the ventral side of the pancreatic head. The cancer had invaded the same location; therefore, the hepatic artery and portal vein were both resected and reconstructed. The patient had no complications, such as postoperative pancreatic fistula, and was discharged 45 days postoperatively. Currently(5 months postoperatively), postoperative S-1-based adjuvant chemotherapy is being administered, and the patient had a recurrence-free survival.
