供肝切取中肝动脉的变异分析

The analysis for the variation of hepatic arteries of the donor livers

目的 探讨肝动脉的变异类型及快速切取供肝过程及修整过程中保护肝动脉不受损伤的方法。方法 回顾性分析2000年5月至2004年3月200例供肝切取及修整过程的资料,总结肝动脉变异情况及肝动脉的重建方法。结果 200例中有37例肝动脉变异, 2例因肝动脉保护不当而出现肝移植术后胆道合并症。结论 大多数的变异肝动脉来源于肠系膜上动脉和胃左动脉;快速整块腹腔器官切取方法是保证肝动脉不受损伤的基础;所有变异的肝动脉均应重建。

Objective To investigate the variations type of hepatic artery and discuss the method of how to protect hepatic artery from injury during the quick harvest of the donor liver. Methods A retrospective review of the variations of hepatic arteries of the donor livers and the course of excision and reconstruction of 200 donor livers was performed, and the aberrance and reconstruction method of hepatic arteries were summarized. Results 37 out of 200 hepatic arteries varied and 2 patients suffered biliary complications because of improper preservation of aberrant hepatic arteries. Conclusions Most aberrant liver arteries come from superior mesenteric artery or left gastric artery. Proper quick harvest of multiple organs is the basis of the integrity of hepatic arteries, and all the aberrance must be reconstructed.
