目的探讨彩色多普勒能量图(CDE)对高血压病患者肾脏血流动力学观测的价值。方法随机选择2009年4月～2011年10月期间在某院治疗的高血压患者121例,并选择78例健康体检者作为对照组。采用CDE检测肾脏血流分布情况及相关参数。结果随着血压增高,高血压病患者肾脏血流信号逐渐减少。随着血压的增高,PSV、S/D、RI及PI增加,而EDV逐渐减少。除了S/D外,其他指标各组间差异均有统计学意义(P﹤0.05)。结论肾动脉血流变化可以作为判断高血压病肾血管损害程度的参考依据。
Objective To investigate the value of color Doppler energy imaging (CDE) on hemodynamics in patients with essential hypertension. Methods A total of 121 hypertensive patients treated in a hospital from April 2009 to October 2011 were randomly selected and 78 healthy subjects were selected as the control group. CDE was used to detect the distribution of renal blood flow and related parameters. Results With the increase of blood pressure, renal blood flow signal of hypertensive patients gradually decreased. With the increase of blood pressure, PSV, S / D, RI and PI increased while EDV decreased gradually. In addition to S / D, the other indicators of the differences between the groups were statistically significant (P <0.05). Conclusion Renal artery blood flow changes can be used as a reference to determine the extent of renal vascular damage in hypertensive patients.
