The anatomy of the hepatic artery and its variations were studied in 70 donor livers harvested for liver transplantation in the Austin Hospital. Forty three (61.5%) had a 'normal' vascular anatomy and 27 (38.5% had anomalous anatomy. The anomalies were single in 13 instances and multiple in 14 and involved the origin of the right or left hepatic arteries or the coeliac axis. The hepatic artery was reconstructed most frequently by end-to-end anastomosis of the donor to the recipient common hepatic artery (79%). A Carrel patch, an interposition aortic graft and the donor superior mesenteric artery were other techniques used for reconstruction. Two patients (3%) had a postoperative hepatic artery thrombosis, with one of those patients having a further reconstruction. When one vascular anomaly is found, there is a high probability of others being present. The authors' experience confirms that safe hepatic arterial anastomosis can be performed even in the presence of abnormalities of the vascular arterial system.
对奥斯汀医院70例用于肝移植的供肝的肝动脉解剖结构及其变异情况进行了研究。43例（61.5%）具有“正常”的血管解剖结构，27例（38.5%）存在解剖异常。这些异常情况中，13例为单一异常，14例为多重异常，涉及右或左肝动脉的起源或腹腔干。肝动脉重建最常用的方法是将供体肝总动脉与受体肝总动脉进行端端吻合（79%）。其他用于重建的技术包括卡雷尔补片、间置主动脉移植和供体肠系膜上动脉。2例患者（3%）术后发生肝动脉血栓形成，其中1例患者进行了再次重建。当发现一处血管异常时，存在其他异常的可能性很大。作者的经验证实，即使存在血管动脉系统异常，也可以进行安全的肝动脉吻合。
