title: Aberrant right hepatic artery with a prepancreatic course visualized prior to pancreaticoduodenectomy.
abstract: Liver vascularization is known to present with several different variations. Generally, a normal vascular anatomy is reported in up to 50-80 % of cases. For this reason, a precise preoperative mapping of the hepatic vascularization prior to pancreatic surgery is essential to avoid injuries and subsequent complications. We report here a case of a young patient scheduled for Whipple procedure, who presented an arterial pattern type Michels IV, variation reported in 0.6 to 3 % in the literature. Another interesting particularity of this case was the fact that the right hepatic artery had a prepancreatic course. We think that every surgeon performing hepatopancreatic surgery should have heard of this special and rare situation.
