Hepatic artery stenosis (HAS) is an infrequent complication of liver transplant; if left untreated, it can lead to hepatic artery thrombosis with high risk of biliary necrosis and graft loss. HAS is diagnosed with screening Doppler ultrasound, together with computed tomography angiography and magnetic resonance angiography. Endovascular treatment with angioplasty ± stent placement is safe and effective with infrequent major complications; however, when complications occur, they can devastate long-term graft survival. Herein, we present two cases of HAS treated with balloon angioplasty with resultant major complications requiring operative intervention.
肝动脉狭窄（HAS）是肝移植中一种罕见的并发症；如果不进行治疗，它可导致肝动脉血栓形成，伴有胆管坏死和移植物丢失的高风险。HAS通过筛查多普勒超声以及计算机断层血管造影和磁共振血管造影来诊断。血管成形术±支架置入的血管内治疗是安全有效的，主要并发症很少见；然而，当并发症发生时，它们可能会破坏移植物的长期存活。在此，我们报告两例经球囊血管成形术治疗的HAS病例，结果出现了需要手术干预的主要并发症。
