摘要

摘要门静脉血栓形成(PVT)是肝脏最常见的血管性疾病之一,发病率和死亡率较高。PVT最常见的病因是肝硬化、肝胆肿瘤、炎症和感染性腹部疾病以及骨髓增生综合征。(1,2)PVT的自然进展导致门静脉高压,导致脾肿大和门体侧支血管的形成,以及胃食管、十二指肠和空肠静脉曲张。超声,尤其是多普勒超声,是评估、监测和诊断肝病患者PVT最广泛使用的成像方法。急性PVT治疗的目的是使阻塞的血管重新透化;在静脉曲张破裂的情况下,内镜下结扎静脉曲张对慢性PVT是安全且非常有效的。总之,PVT是最常见的肝血管疾病,其发病率增加,尤其是在慢性肝病患者中。(3)

Risk Factors Regarding Portal Vein Thrombosis in Chronic Liver Disease
Abstract The portal vein thrombosis (PVT) is one of the most frequent vascular diseases of the liver, with a high rate of morbidity and mortality. The most common causes of the PVT are hepatic cirrhosis, hepatobiliary neoplasms, inflammatory and infectious abdominal diseases, and myeloproliferative syndromes.(1,2) The natural progress of the PVT has as a result portal hypertension which leads to splenomegaly and the formation of portosystemic collateral vessels, as well as gastroesophageal, duodenal and jejunal varices. Ultrasonography, especially Doppler ultrasound, is the most widely used imaging method to asses, supervise and diagnose PVT in patients with hepatopathies. The purpose of acute PVT treatment is to re-permeabilize the obstructed vessels; the endoscopic ligature of the varices in the eventuality of their rupture is safe and extremely efficient in chronic PVT. To conclude, PVT is the most common hepatic vascular disorder, and its prevalence has increased particularly among the patients with chronic hepatopathies.(3)
