【摘要】 目的对肝移植术后肝动脉狭窄的早期诊断及介入治疗进行初步的探讨和分析。资料与方法回顾性分析本院1998年9月至2004年1月进行的450例原位肝移植术后34例肝动脉狭窄、闭塞的诊断及介入治疗资料。对33例肝动脉狭窄的病例行球囊导管扩张治疗,3例扩张治疗无效的患者及1例球囊扩张后出现肝动脉内膜撕裂的患者行内支架置入治疗;1例肝动脉狭窄伴吻合口破裂出血的患者直接行内支架置入治疗。结果30例肝动脉狭窄的介入治疗获得成功,4例患者介入治疗失败。治疗成功的病例术后预后良好,肝功能有明显改善。治疗失败的病例预后不良。结论介入治疗方法对肝移植术后肝动脉狭窄的早期诊断及治疗具有较大的应用价值,肝动脉狭窄应首选球囊扩张治疗,必要时采用内支架置入治疗。更多还原

【Abstract】 Objective To discuss the interventional treatment and early diagnosis in hepatic artery stenosis after orthotopic liver transplantation.Materials and Methods 450 cases after orthotopic liver transplantation, the data of diagnosis and interventional treatment in 34 cases with hepatic artery stenosis or occlusion were retrospectively analyzed. 33 cases with hepatic artery stenosis were treated with balloon dilation, of them, 3 cases failed and 1 case because of laceration in hepatic artery intima were treated with stent.Results 30 cases of hepatic artery stenosis were successfully treated. All of 30 cases had a better outcome following angioplasty with improvement of hepatic function, whereas 4 cases had a bad outcome.Conclusion Interventional treatment is valuable in the early diagnosis and management for hepatic artery stenosis after liver transplantation, balloon dilation is first choice combined with stent.更多还原
