摘要
目的探讨梗阻性黄疸对肝脏血流动力学的影响．方法采用彩色多普勒血流显象仪对２０例梗阻性黄疸患者的肝固有动脉和门静脉血流进行定量测量，并与２０例正常人进行对比分析．结果梗阻性黄疸患者肝固有动脉的峰值流速（ｃｍ／ｓ，９２±１５ｖｓ６９±１９，Ｐ＜００５）、血流量（ｍＬ／ｍｉｎ，７１４±３６３ｖｓ３０５±１２１，Ｐ＜００１）显著高于正常人；门静脉血管内径（ｃｍ，１２５±０２４ｖｓ１０４±０１９，Ｐ＜００１）及门脉充血指数（ｃｍ×ｓ，０１４１±００１３ｖｓ０１１９±００１３，Ｐ＜００１）明显高于正常人．但门静脉血流量及峰值流速则低于正常人．结论彩色多普勒血流显象仪探讨梗阻性黄疸时肝脏血流动力学改变的较理想非创伤性方法。
AIM To observe hemodynamic changes in patients with obstructive jaundice. METHODS We prospectively studied 20 patients with obstructive jaundice and 20 normal subjects by Color Doppler flow imaging (CDFI). RESULTS The results showed that the peak systolic velocity and blood flow of hepatic artery in patient group were significantly higher than that in control group. The diameter and congestion index of portal vein were higher significantly also. But the blood flow and velocity of portal vein in patient group were lower than that in control group. CONCLUSION CDFI for liver hemodynamicl changes is a best method. They play an important role for prognostic evaluation.
