随着影像诊断技术的进步，曾被认为是罕见病的门静脉系统血栓的确诊率迅速上升。全身因素（包括各种促血栓形成的危险因素）以及局部因素（包括肝硬化、腹腔创伤及感染、恶性肿瘤等）均可导致门静脉血栓形成。目前依据临床症状出现时间的长短以及是否存在门脉海绵样变将门静脉系统血栓分为急性和慢性两类，这两类门静脉系统血栓分别具有不同的临床表现及治疗原则。急性血栓的治疗原则为复通闭塞的门静脉，降低血栓进入肠系膜上静脉的危险性；慢性血栓则为治疗和预防门脉高压后产生的并发症。门静脉系统血栓的介入治疗在血管再通、减轻门脉高压引起的并发症以及恢复阻塞静脉血流方面起到很大作用。本文将就门静脉系统血栓从病因到治疗的最新进展做一综述。

With the progress of imaging techniques, the diagnosis rate for portal vein thrombosis (PVT), that is used to be considered as a rare disease, has been rapidly increasing. PVT can be caused by systemic reasons such as various thrombophilic risk factors as well as a lot of local reasons such as cirrhosis, abdominal trauma and infection, malignant tumor, etc. At present, PVT is classified into acute and chronic entities based on the duration of clinical symptoms as well as on the presence or absence of portal cavernous transformation. The clinical manifestations and the treatment principles of the acute and chronic PVT are quite different. For acute PVT, the principle of treatment is to reopen the obstructed portal vein and to prevent the thrombus from entering into the superior mesenteric vein, while for chronic PVT the principle of treatment is focused on the management of the complications due to portal hypertension. The interventional management of portal thrombus plays an important role in reopening portal vein, reducing complications caused by portal hypertension, and restoring portal blood flow, etc. This paper aims to make a comprehensive review about the etiology and management of portal vein thrombosis.
