摘　　要：目的　探讨梗阻性黄疸对肝血流动力学的影响。方法　应用彩色多普勒血流显像仪对 2 0例梗阻性黄疸患者手术前后门静脉、肝固有动脉的血流进行测定。结果　梗阻性黄疸患者手术前门静脉内径、血流速度、血流量显著低于其手术后 (P <0 .0 1,P <0 .0 0 1) ;而手术前肝固有动脉内径、血流速度、血流量显著高于其手术后 (P <0 .0 0 1)。结论　应加强对梗阻性黄疸患者围手术期内肝血流动力学的监测 。Objective To observe hemodynamic changes of liver in patients with obstructive jaundice. Methods The blood flow in portal vein and hepatic artery were quantitively measured by color Doppler ultrasonography before and after surgery in 20 patients with obstructive jaundice. Results The results showed that the diameter,velocity and quantity of portal vein blood flow before surgery in the patients with obstructive jaundice were significantly lower than after surgery ( P <0.01, P <0.001). The diameter,velocity and quantity of hepatic artery blood flow before surgery in the patients with obstructive jaundice were significantly higher than after surgery ( P <0.001). Conclusion Before and after operation, monitor of liver hemodynamics for these patients are needed. It plays an important role in making clinical therapy schedule.
