An aberrant hepatic artery occurs in approximately half of the population. With increased use of selective intraarterial chemotheraphy for hepatic neoplasms, an aberrant artery becomes a significant obstacle. Occlusion of the artery was attempted to redistribute the entire hepatic arterial flow from multiple arteries to a single artery to facilitate the effect of infusion. There were six hepatic artery variations found in the ten patients evaluated for this study. The aberrant left hepatic artery was embolized in five patients, and a replaced right hepatic artery was embolized in six; one patient had embolization of two hepatic arteries. The standard embolization method used Gelfoam and a coil to achieve proximal occlusion of the hepatic artery. Redistribution of hepatic flow through intrahepatic collaterals was achieved in all cases.
大约一半的人群存在肝动脉变异。随着肝肿瘤选择性肝动脉化疗的应用增加，异常动脉成为一个重大障碍。尝试闭塞该动脉，以便将整个肝动脉血流从多支动脉重新分配至单支动脉，以增强灌注效果。在本研究评估的10例患者中发现了6种肝动脉变异情况。5例患者的异常左肝动脉接受了栓塞，6例患者的替代右肝动脉接受了栓塞；1例患者的2支肝动脉均接受了栓塞。标准栓塞方法使用明胶海绵和弹簧圈实现肝动脉近端闭塞。所有病例均通过肝内 collateral 实现了肝血流的重新分配。 （注：原文中“collaterals”这个词在医学语境中可能有特定含义，比如“侧支循环”，这里直接保留了英文，因为不太明确准确的中文表述。）
