肝移植术后并发症的介入治疗

目的:探讨肝移植术后并发症介入治疗的应用。方法:对终末期肝病及肝癌肝移植术及介入处理相关资料进行回顾性分析,并对5例肝移植术后并发肝动脉狭窄及血栓形成的患者行球囊扩张、溶栓、内支架置入术。结果:2例肝动脉狭窄的患者经球囊扩张后临床症状缓解;其中1例发生吻合口出血,置入带膜支架,症状缓解。3例肝动脉血栓形成患者经溶栓后肝动脉血流得到恢复。结论:介入治疗对肝移植术后并发肝动脉狭窄及血栓形成的患者进行治疗是可行的,但须谨慎实施,以免发生出血等并发症,介入技术对肝移植术后早期并发症的诊断和处理有重要价值。

The Preliminary Experience of Interventional Therapy for Hepatic Arterial Complications After Liver Transplantation

Objective To study the interventional therapy for hepaticarterial complications after liver transplantation. Methods To summarize the preliminary experience of interventional therapy for the patient after liver transplantation who suffered from late hepatopathy andhepatocarcinoma . Five patients with hepatic arterial stenosis (HAS) or hepatic arterial thrombosis( HAT) after liver transplantation were treated by percutaneous transluminal angioplasty(PTA),transarterial thrombolysis and stent graft placement. Results The symptoms of two patients with HAS was relieved by percutaneous transluminal angioplasty even though stent graft was placed in one patient with hepatic arterial anastomosis hemorrhage. Immediate blood flow of hepatic artery was restored in three patients with HAT after treating by transarterial thrombolysis. Conclusion Interventional therapy is an effective modality for hepatic arterial stenosis and thrombosis after liver transplantation but they must be performed cautiously to avoid hemorrhagic complications.It is of great value for the diagnosis and treatment of complications in early stage after liver transplantation.
