Aberrant right posterior hepatic artery originating from the gastroduodenal artery with a concomitant replaced left hepatic artery: a rare clinical variant

TL;DR

This paper reports a rare variation in liver blood vessels that could impact surgical outcomes.

Contribution

The study identifies a rare hepatic arterial variant involving an aberrant right posterior artery and a replaced left artery.

Findings

An aberrant right posterior hepatic artery originated from the gastroduodenal artery.

A replaced left hepatic artery was also present in the case.

Such variants are critical to recognize during pancreatic surgery to avoid complications.

Abstract

Variations in the hepatic arterial system, observed in up to 22% of the population, significantly influence the outcomes of hepatobiliary and pancreatic procedures. This study describes an extremely rare variant involving an aberrant right posterior hepatic artery (aRPHA) originating from the gastroduodenal artery (GDA) alongside a replaced left hepatic artery (LHA). Awareness of such variants is critical during pancreaticoduodenectomy to prevent ischemic complications.
