肝移植术后并发症与介入治疗 二、肝动脉狭窄

Interventional therapy of complications after liver transplantation:hepatic artery stricture

移植术后肝动脉狭窄(HAS)可直接导致移植肝功能丧失与胆管并发症。及早发现并明确诊断对预后至关重要,多普勒超声可作为首选的筛查方式,血管造影可以进一步明确诊断。肝动脉狭窄后球囊扩张术仍是有效的方法,如有条件采用冠脉支架对HAS更为合适,尤其是肝动脉扭曲者。但对治疗无效的HAS外科血管再通或再次移植仍是挽救措施。

Hepatic artery stricture （HAS） after liver transplantation can lead directly to transplanted liver function exhaustion and complications of biliary system. The early diagnosis and treatment are crucial for better prognosis. Doppler ultrasound is the first method of choice, and angiography can give further clear dignosis. The balloon dilatation is still effective for hepatic arterial stenosis. With the more adaptable usage of oronary stent, if possible, would reveal more promising result especially for tortuous stenotic hepatic artery. The vascular reconstruction or repeated liver transplantation is still the effective therapeutic methods.
