ABSTRACT Knowledge of the variant vascular anatomy of the subhepatic region is valuable to hepatobiliary surgeons to limit operative complications due to unexpected bleeding. One hundred and two subhepatic regions were studied by gross dissection for the pattern of arterial blood supply. Measurements were made for the distance of hepatic bifurcation from the liver. The common hepatic artery (CHA) originated from the celiac trunk in 95.1% and from the superior mesenteric artery (SMA) in 4.9% of cases. The mean distance of bifurcation from the liver was 2.6cm and the CHA gave rise to 2 hepatic branches in 93.1% of cases. The right hepatic artery (RHA) passed anterior to the CHD in 48%, posterior in 41.2% and in 7.8% was related to the common bile duct (CBD). Accessory RHA and left hepatic arteries (LHA) were observed in 10.8% and 9.8% of the cases. There is wide variation in the pattern of arterial supply to the liver and biliary apparatus in adult Kenyans. A comprehensive understanding and application of this aspect of surgical anatomy is essential for good results to be maintained and even improved when carrying out surgical procedures in this area.
