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
