A RARE VARIANT OF GASTRO-DUODENAL ARTERY ORIGINATING FROM RIGHT HEPATIC ARTERY – IMPLICATIONS DURING PANCREATICO-DUODENECTOMY

Abstract

The presence of arterial variants in patients scheduled for pancreatico-duodenectomy is not uncommon and should be preoperatively detected because it may influence the intraoperative strategy. Ligation of the gastro-duodenal artery is a critical step during pancreatico-duodenectomies. However, the impact of anatomical variants of gastro-duodenal artery was poorly investigated. Hereby, it is presented the case of a patient who underwent pancreatico-duodenectomy for distal bile duct cholangiocarcinoma and with anatomical variant of origin for gastro-duodenal artery from right hepatic artery. Proper recognition of arterial anatomy during pancreatico-duodenectomies is of utmost importance to avoid postoperative complications.
