1、2023单纯门静脉再通术治疗非肝硬化性慢性肝外门静脉阻塞引起的重度门静脉高压非肝硬化性慢性肝外门静脉阻塞(CNC-EHPVo)是一种罕见的肝脏疾病，有发生肝前性门静脉高压及其相关并发症的风险，包括胃肠道(GI)出血、门脉胆管病、腹痛、腹水、血栓蔓延或复发(Intagliatazetal.Gastroenterology.2019,156,1582-1599.e1;NoronhaFerreirazetal.Hepatology.2016z63z1640-1650;Hernandez-Geazetal.JournalofHepatology.2019z71z175-199;Khannazetal.
