高血压患者肾动脉彩色多谱勒分析

Subject Study on Color Doppler Flow of renal arteries in Hypertension patients

目的 采用彩色多谱勒技术探讨高血压对肾动脉的影响。方法 对50例高血压患者与45例血压正常者进行彩色多谱勒超声检查,分别测量和比较两组肾动脉干、肾段动脉、叶间动脉收缩期峰值流速、阻力指数;并对其不同年龄组的变化情况分别进行统计分析。结果 高血压组不同部位肾动脉阻力指数较血压正常组增加,差异均有统计学意义,高血压组3个年龄组间肾动脉阻力指数的差异亦有统计学意义(P<0.01);肾动脉峰值流速高血压组较血压正常组增高,但仅肾动脉干峰值流速的差异有统计学意义。结论 高血压与肾动脉峰值流速、阻力指数及随年龄的变化程度有其相关性;用彩色多谱勒技术对此有较高诊断价值。

[Objective]To investigate the impact of hypertension on renal arteries by using Color Doppler Flow Imaging (CDFI) . [Methods] Maximal systolic velocity (MAX) and resistive index (RI) of renal aorta, renal segmental artery, and leaf artery in 50 hypertension patients and 45 normal people were measured by CDFI, and the result were statistically analyzed. [Results] The RI of renal arteries in hypertension patients increased significantly than that in normal group( P < 0.01) . The Max of renal arteries in hypertension patients increased than that in normal group. But only the difference in renal arteries showed statistic significance. [Conclusion] The Max and RI of the renal arteries were related with hypertension and the age of hypertension patients. CDFI could play an importance role in the diagnosis of hypertension.
