Replaced gastroduodenal artery with continuation as accessory left hepatic artery: a rare anatomical variant.


ABSTRACT: Background:Presented here is a rare case of a gastroduodenal artery (GDA) replaced to the superior mesenteric artery with continuation into an accessory left hepatic artery. To the authors' knowledge, this rare anomaly is not described previously. Replaced GDA is reported, however without continuation into an accessory LHA. Case presentation:A 74-year-old male with recurrent peptic ulcer disease presented with acute onset melena. This anomaly was discovered during abdominal angiography performed for treatment of a hemorrhagic duodenal ulcer. Initial celiac and common hepatic artery (CHA) subselection and angiography demonstrated no branch vessels. Angiography via the superior mesenteric artery demonstrated free extravasation into the duodenum and distal perfusion of the left hepatic lobe. Conclusions:This is a rare variant of hepatic arterial anatomy. Importantly, this variant challenges a previously described anatomical model that attempts to explain observed CHA variation.
