title: Quadrifurcation of the hepatic artery proper in conjunction with double right gastric arteries.
abstract: Descriptions of the variant hepatic arterial pattern are common and frequently reported in anatomy archives. We describe a noteworthy deviation from the usual branching pattern in a single cadaver. There was a unique division of the hepatic artery proper into two right gastric arteries (RGAs), apart from the usual branches. Furthermore, an arterial loop was formed by these two RGAs, giving off another RGA, which we termed 'right gastric proper'. This report attempts to evaluate the embryological basis of the anomaly. The significance of this anomalous hepatic arterial pattern is appreciated while performing liver transplantations, hepatic artery infusion of chemotherapeutic drugs and Doppler angiographic procedures. We advocate meticulous familiarisation with the anatomy of the coeliac trunk and its topographic relationship to vital viscera for the operating hepatobiliary surgeon and radiologist.
