摘要
目的 探讨肝移植术后不同肝动脉狭窄类型治疗时机的选择和疗效.方法 2003年10月至2007年5月,本院共有21例肝移植病人术后发生肝动脉狭窄,其中19例接受肝动脉支架放置术,2例定期随访观察;同时监测介入治疗前后肝功能、肝动脉通畅程度变化及病人临床转归等情况.结果 肝移植术后肝动脉狭窄发生率为3.43%(21/613),诊断中位时间146 d.6例早期肝动脉狭窄病人均接受介入治疗,其中病死2例,存活4例病人中有2例再移植.15例晚期肝动脉狭窄病人中,13例接受介入治疗,其中病死4例,再移植2例,7例存活但肝功能反复出现异常.另外2例在肝门及肝内分支形成良好的侧支循环,肝功能维持稳定.结论 移植术后应根据肝动脉狭窄类型、胆道缺血损伤程度以及有无良好侧支循环代偿等综合因素采取个体化治疗策略.
Objective To determine the timing for therapy and efficacy for different types of hepatic artery stenosis (HAS) after orthotopic liver transplantation(OLT). Methods From October 2003 to May 2007, a total of 21 patients had hepatic artery stenosis after OLT in this hospital. Of the 21 patients, 19 underwent stent placement in their narrowed hepatic arteries and 2 were regularly followed up. Liver function, clinical outcomes, and the hepatic artery potency were reviewed. Results The occurring rate of HAS was 3.43% (21/613) and its median time of diagnosis was 146 days (range, 2-515 days). Six patients with early HAS were treated with interventions and 2 of them died.For the 4 surviving patients, 2 received retransplantation. For the 15 patients with late HAS, 13 were treated with interventions and 4 of them died. Two patients received retransplantation. Seven surviving patients had abnormality in liver function. Another 2 patients had normal liver function because of hepatic portal form compensatory circulation. Conclusion The presence of ischemic bile duct lesion and whether or not favourable compensatory circulation exists or not should be considered before individualized therapeutic regimens adopted according to postoperative HAS types.
