摘要
门静脉高压症是消化系统常见病,指门静脉血流压力增高。肝硬化引起的门静脉高压症患病率高,目前认为由门静脉阻力(R)增加和门静脉血流量(Q)增加所致,肝脏结构改变所致的机械梗阻与神经、体液及代谢因素一同发挥着重要作用。临床表现包括腹腔积液、脾大、侧支循环形成与开放。诊断时须符合以下条件:满足肝硬化及门静脉高压症的诊断,但除外其他病因。
Summary：Portal hypertension （PH） refers to a common digestive system disease with elevated blood flow pressure in the portal vein. The cirrhosis-induced PH has a high incidence rate, which is mainly believed to be caused by an increase in resistance （R） and an increase in blood flow quantity （Q）. Mechanical obstruction in- duced by altered liver structure together with nerve, body fluids and metabolic factors also play an important role in PH development. The clinical manifestations include ascites, splenomegaly and formation and opening of collateral circulations. The diagnostic criteria for cirrhosis and PH should be met when determining on a diagnosis, along with other causes ruled out.
