Abstract
Knowledge of hepatic arterial vascularization and its variations have a significant relevance for the daily practice of hepato-biliary surgeon as well as radiologists. Human cadaver livers (n=60) were obtained from routine autopsies. Resections were carried out en bloc with liver, celiac trunk (CT), left gastric artery (LGA), lesser omentum, superior mesenteric artery (SMA) and head of the pancreas. We have found one case with an exceptional anatomic variation, replaced left hepatic artery (LHA) coming off the SMA directly to the hepatic left lobe. We would like to draw attention for this particularly anatomic variation of the origin of the LHA ensuring that no damage will be made during gastrointestinal surgery.
Keywords: Liver anatomy, left hepatic anomaly, superior mesenteric artery.
