肝硬化门静脉高压的并发症往往带来不良的预后,腹水患者5年生存率为20%,静脉曲张出血患者1年生存率亦为20%左右。非肝硬化性门静脉高压(NCPH)较少见,其预后亦截然不同,Kingham 等的研究表明,其5年生存率为90%,30年生存率为55%。NCPH 首先必需与门静脉高压的肝外原因(特别是特发性或医源性门静脉血栓形成)鉴别。在Kingham 报道的41例施行静脉造影的患者中,13例证实有门静脉系统轻微异常(包括部分闭塞)。较少 Complications of cirrhosis and portal hypertension often lead to poor prognosis. The 5-year survival rate of patients with ascites is 20%. The 1-year survival rate of patients with variceal bleeding is also about 20%. Non-cirrhotic portal hypertension (NCPH) is rare, and its prognosis is also very different, Kingham et al study showed that the 5-year survival rate was 90%, 30-year survival rate was 55%. NCPH must first be distinguished from extrahepatic causes of portal hypertension, particularly idiopathic or iatrogenic portal vein thrombosis. Thirteen of the 41 patients undergoing venography in Kingham reported minor abnormalities in the portal system (including partial occlusion). less
