| 摘 要： | 应用双功多普勒检测了３２例正常对照者，３８例慢性肝炎，１７例肝硬化和３２例原发性肝癌患者的门脉血流动力学，发现肝硬化，原发性肝癌组门静脉内径显著大于正常对照组和慢性肝炎组；门脉血流速度则三组患者均显著低于对照组；门脉血流量仅慢性肝炎组显著低于对照组；三组患者的门脉充血指数均显著大于对照组。本文初步探讨了门脉血流动力学检测的临床意义及各种生理因素对门脉血流的影响。

| Abstract: | The portal hemodynamics was studied by using duplex Doppler in 32 normal subjects and 87 patients including 38 chronic hepatitis (CH), 17 liver cirrhosis(LC), and 32 primary hepatic carcinoma(PHC). The diameter of portal vein in LC and PHC was significantly larger than in CH and control group. The portal venous velocity was slow in CH, LC and PHC. However, portal venous flow was only reduced in CH. The congestive index of portal vein increased in LC, PHC and CH. The measurement of portal hemodynamics is helpful to differ LC from CH and to assess the portal vein invaded by tumour. The physiological factors affecting portal hemodynamics were discussed. |
