HEPATIC ARTERY ANATOMIC VARIATION: IMPORTANCE OF PREOPERATIVE PLANNING

Authors

Keywords:

aberrant hepatic artery, duodenopancreatectomy, anatomy, Michels, Hiatt

Abstract

Anatomic variations of the hepatic artery are not uncommon and may lead to iatrogenic injuries during pancreatoduodenectomy (PD). Two classifications (Michels’ and Hiatt’s) have been used to describe the different variations. Ligation of an aberrant hepatic artery may result in life-threatening complications, such as liver necrosis. Preoperative imaging is crucial for detection of these variations.
