摘　　要：目的评价彩色多普勒超声检测心肾综合征肾内动脉血流动力学变化的临床价值。方法将慢性心力衰竭分为肾功能正常组和慢性肾功能不全组,应用彩色多普勒技术检测两组肾内段动脉、叶间动脉的收缩期峰值流速及阻力指数,并与正常对照组比较。结果慢性肾功能不全组段动脉及叶间动脉的收缩期峰值流速较肾功能正常组减低(P<0.01),而阻力指数较肾功能正常组显著增高(P<0.01),较正常对照组也显著增高。结论心肾综合征患者肾内动脉于收缩期及舒张期处于低血流速,而肾血管处于高阻力状态。Objective To evaluate the clinical value of renal haemodynamics changes in patients with cardiarenal syndrome. Methods All patients with chronic heart failure were divided into two groups by blood creatinine. The maximal velocity and resistance index of segmental and interlobar renal arteries were examined by color Doppler ultrasonagraphy, and compared with normal group. Results In patients with cardiarenal syndrome, the maximal velocity of segmental and interlobar renal arteries were significantly lower（P 〈0.01）. The resistance index were significently higher （P 〈0.01）. Conclusion The intrarenal arteries of patients with cardiarenal syndrome are in lower systolic and diastolic flow velocity, but higher renal vascular resistance.
