Evaluation Of Branching Pattern Of Hepatic Artery

Abstract

The incidence of normal hepatic arterial anatomy ranges between approximately 50-80% 1-6 of individuals. Knowing anomalous origin of hepatic arteries is important for successful cholecystectomy, hepatobiliary and liver transplant surgery. The present work is a descriptive study which emphasizes to document the normal anatomy and different variations of extra hepatic biliary apparatus and was conducted in Department of Surgery and Anatomy, LLRM Medical College, Meerut and SIMS, Hapur. The study revealed that in all cases, the division of proper hepatic artery was extra-hepatic, of which 92% the point of division was proximal to the point of union of hepatic duct, whereas in 8% cases the point of division was higher. In 86%, the right hepatic artery was dorsal to the common hepatic duct. In 4% cases the artery crossed ventral to common hepatic duct. In 93.5% cases branching pattern of common hepatic artery was normal, 1.5% cases showed trifurcation of common hepatic artery with absence of proper hepatic artery, and aberrant or accessory hepatic artery was present in 5% cases. CONCLUSION: familiarity with vascular Anatomy of sub hepatic region is useful for planning and conduct of radiological as well as surgical procedures of upper abdomen including laparoscopic operations of biliary tract.
