为了解肝硬化门脉高压病人门脉系统循环情况及为临床门脉高压的药物治疗提供客观依据，应用彩色多普勒超声检测２０例肝硬化病人及１５例正常人门脉系统血流动力学改变。结果：肝硬化门脉高压症病人门静脉、脾静脉、肠系膜上静脉的血管直径、血流速度、血流量均大于正常人（Ｐ＜０００５），而且发现门静脉血流量增加主要是脾静脉血流量增加所致．结论：肝硬化门脉高压病人存在门脉高动力循环状态，这对临床选择有效的治疗门脉高压症的方法有重要价值。
To understand the portal system circulation in cirrhotic patients with portal hypertension and provide an objective basis for clinical treatment of portal hypertension, the portal hemodynamics of 20 patients with cirrhosis and 15 normal controls were examined by color Doppler sonography change. Results: The diameter of portal vein, splenic vein and superior mesenteric vein in cirrhotic patients with portal hypertension were significantly higher than those in normal subjects (P <0005), and the increase of portal vein blood flow was mainly in splenic venous blood Due to increased traffic. Conclusion: There are portal hyperdynamic circulation in cirrhotic patients with portal hypertension, which is of great value in the clinical choice of effective treatment of portal hypertension.
