彩色多普勒超声对亚临床肝肾综合征的诊断价值

目的 探讨彩色多普勒超声检查在临床诊断亚临床肝肾综合征中的应用价值.方法 应用彩色多普勒超声检测肾功能正常的肝硬化代偿期患者(30例)和肝硬化失代偿期患者(30例)的主肾动脉内径(D)及肾脏血流动力学参数[收缩期峰值流速(PSV)、舒张末期流速(EDV)及阻力指数(RI)],并与健康者(对照组,30例)对照.结果 肝硬化失代偿组患者主肾动脉D[(0.39±0.06)cm]较对照组[(0.56±0.05)cm]及肝硬化代偿组[(0.53±0.04)cm]显著减小,差异有统计学意义(P＜0.01);肝硬化失代偿组患者肾动脉EDV[(16.0±5.4)cm/s]亦显著低于对照组[(29.2±6.0)cm/s]及肝硬化代偿组[(28.6±5.9)cm/s],差异有统计学意义(P＜0.01);肝硬化失代偿组患者肾动脉RI(0.73±0.06)显著高于对照组(0.60±0.04)及肝硬化代偿组(0.61±0.05),差异有统计学意义(P＜0.01).3组肾动脉PSV间差异无统计学意义(P＞0.05).结论 彩色多普勒超声能敏感、客观地评价肾功能正常的肝硬化患者肾脏血流动力学紊乱情况,进而了解肾小球滤过率和肾血流状态,对亚临床肝肾综合征的早期诊断有重要价值.

Value of Color Doppler Ultrasonography in the Diagnosis of Preclinical Hepatorenal Syndrome

Objective To evaluate the value of color Doppler ultrasonography used in the diagnosis of preclinical hepatorenal syndrome (HRS).Methods Color Doppler ultrasonography was applied to detect the inner diameter of renal artery and the renal hemodynamic parameters including peak systolic velocity (PSV),end diastolic velocity (EDV) and resistive index(RI) in hepatic cirrhosis patients with normal renal function who were at compensation stage (n=30)and at decompensation stage (n=30),and the results were compared ...
