2、、MRI、胆道造影和血清学检查了解移植肝形态、血流动力学及肝功能。98例随访2～48个月。结果发生胆道并发症24例(18%)，其中因肝动脉狭窄或栓塞引起的胆漏、胆道狭窄和肝内局限性坏死7例(5例经溶栓及内支架介入治疗后恢复、2例因肝功能衰竭并感染死亡)；胆道狭窄8例(6例经再次手术和ERCP及PTCD胆道内、外支撑等介入治疗恢复、2例胆管消融并发胆管炎死亡)；胆漏7例(6例经再次手术或超声引导下穿刺置管引流治愈、1例保守治愈)；胆道铸型2例(均经再次手术治愈)。结论供肝的质量和完整的动脉采集及胆道黏膜的保护，精细的动脉和胆管吻合是预防肝移植术后胆道并发症

3、的关键。肝动脉溶栓、ERCP及PTCD胆道内支撑等是治疗胆道并发症的有效手段。【关键词】 肝脏移植；胆道并发症   【Abstract】 Objective Toinvestigatethepreventionandmanagementmethodsofbiliarycomplicationsafterorthotopiclivertransplantation(OLT).Methods Aretrospectiveanalysiswasdoneon160patientstreated
