肝硬化患者彩色多普勒超声检测入肝血流变化的临床评价

摘要

Objective Study of patients with compensated cirrhosis and clinical prognosis in patients with decompensated cirrhosis, hepatic artery portal vein hemodynamic changes.Methods According to the liver cir hosis clinical type is divided into compensatory and decompensated cir hosis of two kinds, we selected 97 cases of compensatory cir hosis, 55 patients with decompensated cirrhosis, the other 50 cases selected healthy control group. Application of color Doppler ultrasound to detect the portal vein diameter (Dpv), mean blood flow velocity (Vpv), portal venous blood flow (Qpv), hepatic artery peak velocity (Psv), mean velocity (Tav), pulsatility index (PI), resistance index (RI).Results Cir hosis patients with portal vein increased, the portal vein velocity slowed down, reduced blood flow, hepatic artery peak velocity and pulsatility index increased, compared with compensated cir hosis patients and the control group, with statistical significance.Conclusion Color Doppler ultrasound in patients with decompensated cirrhosis portal vein, hepatic artery blood flow changes in the clinical treatment, assessment of severity and prognosis have important value.%目的：探讨代偿性肝硬化患者及失代偿性肝硬化患者门静脉、肝动脉血流动力学变化的临床预后评价。方法根据肝硬化临床分型分为代偿期及失代偿其两类肝硬化,选取97例代偿期肝硬化,55例失代偿期肝硬化,另选取50例健康人为对照组。运用彩色超声多普勒检测各组门静脉主干内径(Dpv)、平均血流速度(Vpv)、门静脉血流量(Qpv),肝动脉峰值流速(Psv)、平均流速(Tav)、搏动指数(PI)、阻力指数(RI)。结果肝硬化失代偿性患者门静脉主干增大,门静脉流速减慢,血流量减少,肝动脉峰值流速及搏动指数增加,与代偿期肝硬化患者及对照组比较有差异,具有统计学意义。结论彩色多普勒超声检测肝硬化患者的门静脉、肝动脉血流的改变对临床治疗、评价病情及预后有重要价值。
