摘要
目的 :探讨肝外梗阻性黄疸对肝脏血流动力学的影响。材料和方法 :应用彩色多普勒血流显像仪测定 2 3例肝外梗阻性黄疸患者的肝固有动脉和肝左静脉血流 ,并与 2 3例单纯胆囊结石患者和 2 3例正常人对比。结果 :肝外梗阻性黄疸患者肝固有动脉内径、血流速度、血流量显著高于正常人和单纯胆囊结石患者 ;而正常人和单纯胆囊结石患者之间无差别。肝左静脉血流测值在各组之间均无显著差别。结论 :梗阻性黄疸时肝固有动脉血流量明显增多 ;肝左静脉病变较门静脉轻。
Purpose: To Observe hemodynamic changes of liver in patients with obstructive jaundice. Materials and Methods: The blood flow in hepatic artery and left hepatic vein were quantitively measured by color Doppler ultrasonography in 23 patients with extrabiliary tract obstructive jaundice (group A), 23 patients with gallbladder stones (groupB)and 23 normal adults (groupC). Results: The results showed that the diameter, velocity and quantity of hepatic artery blood flow in group A were significantly higher than those of groups B and C (P<0 001). Left hepatic vein blood flow in group A, group B and group C were not significantly different (P>0 05). Conclusion: The hepatic artery blood flow was significantly increased in obstructive jaundice patients. The hepatic vein was less affected than portal vein.
