The course of the hepatic inferior vena cava (HIVC) has a wide range of variations which are relevant in hepato-vascular surgery and liver transplantation. Eighty livers were studied for hepatic course and axial orientation of the HIVC. The HIVC was found to run in an incomplete tunnel in 43.8% of the cases (n = 35), complete tunnel in 32.5% of the cases (n = 26) while in the rest, it was contained in a shallow groove on the retrohepatic surface. It assumed an oblique course in relation to the longitudinal axis of the liver in 60% of the cases (n = 48). The findings of this study vary to a wide range from those reported previously, and call for extra caution during surgical operations involving the HIVC region.
肝下腔静脉（HIVC）的走行存在广泛变异，这在肝血管手术和肝移植中具有重要意义。对80个肝脏的HIVC走行和轴向进行了研究。发现43.8%的病例（n = 35）中HIVC走行于不完全隧道内，32.5%的病例（n = 26）中走行于完全隧道内，其余病例中，它位于肝后表面的浅沟内。60%的病例（n = 48）中，HIVC相对于肝脏纵轴呈斜行走行。本研究结果与先前报道的差异很大，在涉及HIVC区域的手术操作中需要格外谨慎。
