摘　　要：目的:探讨肝硬化患者拇指动脉管径和血流动力学改变。方法:采用彩色多普勒超声检测60例肝硬化患者拇指动脉的管径、血管收缩期最高血流速度(Vmax)、舒张末期最低血流速度(Vmin)及阻力指数(RI)。结果:肝硬化患者拇指动脉的内径增宽、Vmax增高,失代偿期肝硬化患者的Vmin降低,与正常组比较,P<0.05;有肝掌的肝硬化患者拇指动脉内径明显增宽、Vmin明显减缓,与无肝掌的患者比较,P<0.05。结论:肝硬化患者存在外周血管扩张和心输出量增加的改变,失代偿期患者的血液淤滞状态更为明显;有肝掌的肝硬化患者更易出现失代偿改变。Objective： To study the diameter and hemodynamies of the right thumb artery in patients with liver cirrhosis.Methods： Sixty patients with liver cirrhosis （30 compensated, 30 decompensated） and 30 controls were enrolled in the study. Measurements of diameter, Peak Systolic Velocity （Vmax）, End Diastolic Velocity （Vmin） and Resistance index （RI） were done using color Doppler ultrasound.Results： The diameter and Vmix in patients with liver cirrhosis were significantly greater, and Vmin in patients with decompensated cirrhosis was significantly decreased, than those in the control. To compare with the patients without liver palms, the diameter was greater and the Vmin decreased than thee with liver palms. Conclusion： Peripheral vasodilatation and augmentation of cardiac ouptut occurred in patients with liver cirrhosis. Abnormality of hemodynamics in patients with decompensated cirrhisos or with liver pahms is more marked.
