Abstract： 目的评价介入技术治疗原位肝移植后肝动脉狭窄(HAS)的效果.方法对原位肝移植术后发生HAS的7例患者进行介入治疗,4例于移植术后7～20 d发生肝脏缺血并发症,3例于移植术后3～6 d发生HAS.介入治疗方法有肝动脉内留置导管持续给予低剂量尿激酶进行溶栓和肝动脉内支架置入术.结果3例为肝动脉吻合口狭窄,狭窄程度＞70%;4例为肝固有动脉完全阻塞,经肝动脉内留置导管溶栓3～7 d后开通,但均存在肝动脉吻合口狭窄,狭窄程度＞90%.7例肝动脉内置入支架均成功,术后2周肝功能明显改善,未发生与介入治疗相关的并发症.术后随访4～18个月,一般情况良好,超声波复查,显示肝动脉血流通畅.结论血管内支架置入术是治疗原位肝移植后HAS的一种安全、有效的方法.
