ABSTRACT


In a setting of living-donor liver transplant and patients undergoing extended hepatic resections for both primary and metastatic liver tumors, preoperative assessment of hepatic arterial anatomy is very important because of the risk of ischemic complications in the event of inadvertent injury to the arterial supply. Anatomical variations in hepatic arterial supply to the liver are very common and seen in nearly half the population. Identifying anomalous origin of segment 4 hepatic artery is vital since this vessel can cross the transection plane and can result in liver ischemia and liver failure. The purpose of our study is to study the variations in hepatic arterial anatomy to segment 4 of the liver in the Indian population.
Keywords: Arterial supply, computed tomography angiography, segment 4
