目的:探讨多普勒超声检查在临床诊断肾动脉狭窄中的意义。方法:回顾性分析我院自2012年7月至2014年8月确诊的38例肾动脉狭窄患者的临床资料。结果:本组38例肾动脉狭窄患者经多普勒超声检查确诊率为93%。多普勒超声诊断狭窄处显示血流速度增高,峰值流速范围约2.0~3.2m/s,相应肾内段动脉和叶间动脉频谱多呈慢波形态,测定Ac:1.1~2.7m/s,TAC:0.11~0.39s。结论:多普勒超声检查对肾动脉狭窄可起到重要的辅助确诊作用。
Objective: To investigate the significance of Doppler ultrasonography in the diagnosis of renal artery stenosis. Methods: The clinical data of 38 patients with renal artery stenosis diagnosed in our hospital from July 2012 to August 2014 were retrospectively analyzed. Results: 38 cases of renal artery stenosis in this group confirmed by Doppler ultrasound was 93%. Doppler ultrasound diagnosis of stenosis showed increased blood flow velocity, peak velocity range of about 2.0 ~ 3.2m / s, the corresponding internal segments of arteries and interlobar arteries were mostly slow wave spectrum, measured Ac: 1.1 ~ 2.7m / s, TAC: 0.11 ~ 0.39s. Conclusion: Doppler ultrasound examination of renal artery stenosis can play an important auxiliary diagnosis.
