Abstract Body : Objectives:

Recently, due to the rapid increase in the number of liver transplants from living donors, the knowledge of variations of hepatic artery anatomy has become important. Appropriate evaluation of hepatic arteries is essential for reducing operative and post-operative morbidity and mortality both in donors and recipients. The aim of this anatomical study is to analyze the variations of the branching pattern of the hepatic arteries in 100 adult human cadavers of Indian origin.

Material and Methods

This study reviewed the anatomical variations in the branching patterns of hepatic arteries in 100 adult human cadavers (M: 82, F: 18) during educational dissection in the Department Of Anatomy, Siddhartha Medical College, Vijayawada for 13 consecutive years from 2006 to 2019. The dissection was done following the standard dissection procedures and the variations of the hepatic arteries were carefully observed and photographed. The classification of hepatic arteries was done following the Michel’s classification of types I to X.

Results

Out of 100 cadavers studied, the normal branching pattern of hepatic arteries (Michel's Type I) was present in 60. The remaining 40 cadavers exhibited various anatomical variations, encompassing Michel's Types II to IX.

Conclusion

Preoperative knowledge and identification of the origin, course, and variations of the hepatic artery are crucial for surgeons and interventional radiologists to perform hepatic surgery or trans arterial chemoembolization successfully and safely.
