Study of anatomical variations of hepatic vasculature using multidetector computed tomography angiography.

Purpose: Preoperative evaluation of the hepatic vasculature is necessary to minimize mortality and morbidity during various surgeries due to the complexity of liver anatomy. The purpose of our investigation is to determine the anatomical variations in the hepatic vascular system by using multidetector computed tomography.

Methods: In this observational study, 500 patients aged between 1 and 86 years were randomly chosen from a patient population referred for computed tomography angiography for various clinical indications.
