- Abstract: Vascular anomalies are a serendipitous finding during surgeries and diagnostic angiography. Such variations are frequently encountered in the abdominal region. These anomalies are usually asymptomatic but the presence of hepatic arterial variations may lead to injuries of the liver during surgery. The present study was conducted on 35 adult embalmed cadavers, 31 males, 4 females from August 2015 to December 2021 in the Department of Anatomy, Amrita School of Medicine, Amrita Institute of Medical Sciences, Kochi. In this study of 35 cadavers, we present 3 variants: an accessory right hepatic artery, replaced common hepatic artery, replaced common hepatic artery anastomosis with accessory left hepatic artery and an arc of Buhler. One of our variants has not yielded a precedent in literature search. We have compared these variants with Michels and Hiatt classification. It is known that different variants arise at distinct stages of embryonic development. As specialists in anatomy, we have tried to correlate the variants in our study with their embryological origins.
