ABSTRACT
We report an autopsy on a 46-year-old man, a case that presented the concurrence of two rare vascular variations of the lesser omentum: aberrant right gastric vein draining directly into the liver, and multiple hepatic arteries. Although the left gastric vein emptied into the left aspect of the portal vein, the right one was found to ascend from the gastric lesser curvature along the right aspect of the common bile duct and to reach directly the porta hepatis. A left hepatic artery originating from the left gastric artery entered the porta hepatis in conjunction with the left ramus of the portal vein. A predominant right hepatic artery arose from the superior mesenteric artery and entered the porta hepatis in conjunction with the right ramus of the portal vein. The proper hepatic artery originating from the celiac artery entered the porta hepatis in conjunction with the aberrant right gastric vein. The possibility of a common underlying mechanism for these rare vascular variations is discussed.
