ABSTRACT

Background:  With ever increasing load of liver disease on population of developed as well as developing countries, it has become mandatory to have a detailed knowledge about hepatic arteries. Since adequate literature regarding hepatic arteries and its variation e in people living in and around Eluru  is not available, a study of hepatic arteries ad its variation is carried out in our ASRAM medical college, Andhra Pradesh, India.

Aims and objectives:  To study  the variations in the origin, course of right hepatic artery

Materials and methods:  This study was conducted in 60 embalmed adult cadavers of both sexes of age group between 50 to 80 years. The common hepatic artery and its branch gastroduodenal artery were identified. Proper hepatic artery in the hepatoduodenal ligament was traced and the relation of the common hepatic artery and the proper hepatic artery were noted. Origin of the RHA was traced and the presence of aberrant right hepatic arteries: (i) Replaced; (ii) Accessory were noted. To identify the presence of aberrant right hepatic arteries, abdominal aorta was exposed from the level of origin of the coeliac trunk to the level of origin of the inferior mesenteric artery.

Results: In this study,  the  right hepatic artery originates from the proper hepatic artery in 24 (60%) specimens.The aberrant, accessory and replaced right hepatic artery  were found to be 20%, 12.5%, and 7.5% respectively. 5% of specimen showed caterpillar hump in right hepatic artery.

Conclusion: Right hepatic artery is subject to anatomical variation in its origin and course. Because of anatomic variations in the RHA, surgical injuries in the liver can occur even by the most experienced surgeon. A thorough knowledge of the RHA anatomy is necessary while performing hepatic surgery and hepatic arteriography

KEY WORDS: Right Hepatic Artery, Hepatic Artery, Hepatic Artery Variations.
