Objective To investigate the diagnosis and treatment of celiac arterial stenosis / occlusion after liver transplantation. Methods Retrospective analysis of clinical data, diagnosis and treatment of 4 patients with celiac arteriall stenosis / occlusion after liver transplantation. Results In this group of 4 patients with celiac arterial stenosis / occlusion after liver transplantation, the clinical manifestations were non-specific. Routine ultrasonography after surgery showed that the hepatic artery resistance index（RI）was less than 0.5, and hepatic artery stenosis was suspected. Later, hepatic arterial CT angiography（CTA）was used to confirm the diagnosis（the first 3 patients were diagnosed with stenosis and the latter patient was diagnosed with complete occlusion）, and 3 of them underwent interventional stent placement, one patient underwent balloon dilation. The success rate was 100%. The blood flow was completely restored. No complications related to interventional surgery and celiac arterial stenosis / occlusion occurred. The first 2 patients were followed up for more than 12 months, and the last 2 patients were followed up for more than 6 months. Ultrasound showed no significant abnormal hepatic artery blood flow. Conclusion For patients with celiac artery stenosed / occluded after liver transplantation, there is usually no clinical manifestation. Color Doppler ultrasound has an early suggestion, CTA examination of the hepatic artery can determine the location and degree of stenosis. And once the diagnosis is clear, interventional therapy is safe and effective and should be used as the preferred treatment

目的 探讨肝移植术后腹腔干动脉狭窄 / 闭塞的诊断与治疗。方法 对 4 例肝移植术后腹腔 干动脉狭窄 / 闭塞患者的临床资料、诊断及治疗情况进行回顾性分析。结果 本组 4 例肝移植术后腹腔干 动脉狭窄 / 闭塞的患者，临床表现无特异性表现，术后早期常规超声检查均提示 ：移植后肝动脉阻力指数 （RI）＜ 0.5，可疑肝动脉狭窄。后均通过肝动脉 CT 血管成像技术（CTA）明确诊断（前 3 例患者诊断腹腔 干动脉开口狭窄，后 1 例患者诊断腹腔干动脉完全闭塞），其中有 3 例行介入内支架技术治疗，1 例行球囊 扩张治疗，手术成功率 100%，血流完全恢复通畅，术后未出现与介入手术及腹腔干动脉狭窄 / 闭塞等相关 并发症。前 2 例患者随访观察超过 12 个月，最后 2 例随访观察超过 6 个月，超声示肝动脉血流均未见明显 异常。结论 对于肝移植术后腹腔干动脉狭窄 / 闭塞的患者，临床通常无特征性表现，彩色多普勒超声对 腹腔干动脉狭窄有早期提示的作用，肝动脉 CTA 检查可以明确狭窄部位、程度，且一旦诊断明确，介入治 疗是安全有效的，应作为首选的治疗方法。
