目的:总结覆膜支架腔内修复治疗肝移植术后肝动脉假性动脉瘤的初步经验。方法:对4例肝移植术后肝动脉假性动脉瘤患者行动脉造影检查,覆膜支架腔内修复治疗。结果:所有患者肝动脉假性动脉瘤均通过动脉造影明确诊断。2例患者经覆膜支架腔内修复治疗痊愈,1例患者经覆膜支架腔内修复治疗1周后出现内漏,经植入裸支架和瘤腔栓塞治疗痊愈。1例覆膜支架植入失败。结论:覆膜支架腔内修复术是治疗肝移植后肝动脉假性动脉瘤的有效方法。
OBJECTIVE: To summarize the preliminary experience of endovascular stent-graft repair of hepatic artery pseudoaneurysm after liver transplantation. Methods: Four patients with hepatic artery pseudoaneurysm underwent arterial angiography and endovascular stent-graft repair. Results: All patients with false hepatic artery aneurysm were confirmed by arteriography. Two patients underwent endovascular stent-graft restoration. One patient underwent endovascular stent-graft restoration after one-week endovascular treatment. The stent was cured by implantation of bare stent and embolization. One case of stent graft failure. Conclusion: Endovascular stent-graft repair is an effective method for the treatment of hepatic artery pseudoaneurysm after liver transplantation.
