Extrahepatic portal vein obstruction is a vascular disorder of liver, which results in obstruction and cavernomatous transformation of portal vein with or without the involvement of intrahepatic portal vein, splenic vein, or superior mesenteric vein. Portal vein obstruction due to chronic liver disease, neoplasm, or postsurgery is a separate entity and is not the same as extrahepatic portal vein obstruction. Patients with extrahepatic portal vein obstruction are generally young and belong mostly to Asian countries. It is therefore very important to define portal vein thrombosis as acute or chronic from management point of view. Portal vein thrombosis in certain situations such as liver transplant and postsurgical/liver transplant period is an evolving area and needs extensive research. There is a need for a new classification, which includes all areas of the entity. In the current review, the most recent literature of extrahepatic portal vein obstruction is reviewed and summarized.
肝外门静脉阻塞是一种肝脏血管疾病，可导致门静脉阻塞及海绵样变，可伴有或不伴有肝内门静脉、脾静脉或肠系膜上静脉受累。由慢性肝病、肿瘤或手术后引起的门静脉阻塞是另一种情况，与肝外门静脉阻塞不同。肝外门静脉阻塞患者通常较为年轻，且大多来自亚洲国家。因此，从治疗角度将门静脉血栓形成定义为急性或慢性非常重要。在某些情况下，如肝移植及术后/肝移植期间的门静脉血栓形成是一个不断发展的领域，需要广泛研究。需要一种新的分类方法，涵盖该疾病的所有方面。在本综述中，对肝外门静脉阻塞的最新文献进行了回顾和总结。
