Abstract:
Hepatic artery variations are important to the surgeons performing procedures in and around the porta hepatis in order to avoid injury to vascular and ductal structures. This cross sectional study was carried out in the Departments of Anatomy and Radiodiagnosis, KGMU, U.P, Lucknow, India. CT-angiograms of 50 subjects were analyzed. Various patterns of hepatic arterial anatomy were observed in the study. These included, normal anatomical origin of CHA from the celiac trunk in 95.92% with CHA displaying a variant anatomical relationship in 2.04% cases. Anomalous origin of CHA from the aorta was found in 4.08% cases. Replaced RHA was found in 16% whereas accessory RHA was found in 14% cases. Observations of LHA anatomy displayed replaced origin from CHA and LGA whereas accessory LHA could be traced to the LGA. Variant arteries displayed an anomalous course.
