肝移植术后肝动脉栓塞的诊治进展

Progress in the diagnosis and treatment of hepatic artery thrombosis after liver transplantation

肝动脉栓塞（HAT）是肝移植术后最常见的血管并发症，是导致移植术后移植物原发性无功能、移植物丢失和移植患者死亡的重要原因。肝移植术后肝动脉栓塞分为早期肝动脉栓塞（E—HAT）和晚期HAT（L-HAT）。由于其病因复杂，临床表现各异，治疗效果亦有争议。因此，对肝移植术后HAT的早发现、早诊断、早治疗非常重要。本文就肝移植术后HAT的诊治进展展开综述。

Hepatic artery thrombosis （HAT） is the most frequent vascular complication following with liver trans- plantation, whichis the foremost cause of primary graft nonfunc- tion, graft loss and recipient＇ s death. Hepatic artery thrombosis after liver transplantation wasdivided into early hepatic artery thrombosis （E-HAT） and late hepatic artery thrombosis （L-HAT）. And the etiologywascomplex, clinical presentations were diversity, treatment effects were controversial, therefore, the early detection, early diagnosis and early treatment of hepa- tic artery thrombosis after liver transplantation are very impor- tant. In this paper, the progress in the diagnosis and treatment of hepatic artery thrombosis after liver transplantation were re- viewed.
