[摘要】 目的探讨彩色多普勒超声在肾动脉狭窄诊断中的临床应用价值。方法 收集经临床医生初步诊 断为药物难治性高血压(尤以舒张压增高为主)的患者60例,共119支肾动脉。在肾动脉条件下首先观察肾动脉 主干有无狭窄所致的花色血流信号,初步判断狭窄的部位;再测量肾动脉水平部腹主动脉,花色血流信号处,肾动 脉主干近、中、远段及肾内段,叶间动脉的血流参数;同时采集肾内叶间动脉频谱声像图,测量各动力学参数。依据 彩色多普勒超声(CDFI)检查成功的标准,按内径减少百分比得出肾动脉狭窄程度,同期行肾动脉血管造影。将 CDFI检查的肾动脉狭窄程度与“金标准”血管造影(DSA)结果相对比。结果彩色多普勒测量不同狭窄组患者各 血流动力学参数呈明显改变:CDFI诊断肾动脉狭窄的敏感性92.5%、特异性95.0%,符合率94.2%;轻度狭窄的 敏感性100.0%,特异性97.1%;中度狭窄的敏感性85.7%,特异性100.0%;重度狭窄的敏感性96.2%,特异性 90.9%。结论CDFI为诊断肾动脉狭窄提供了简便、准确的影像学检查方法,进一步为临床选择合理的治疗方法 提供了可靠依据。 [关键词] 肾动脉狭窄;彩色多普勒超声;血流动力学;小慢波 [中图分类号]R543.5 [文献标识码]A

measurements of PSV,AT,AC,RI,RPSV,RAR and RIR;were calculated.Through application of various blood fluid mechanics pa- rameters along with spectral shape changes and CDFI criteria,the location and severity of renal artery stenosis were determined.Compa- ring Doppler ultrasound results in renal artery stenosis severity with the renal artery angiographic results.Results Renal artery Color doppler ultrasound diagnosis of renal artery stenosis had a sensitivity of 92.5%and a specificity of 95.0%.Diagnosis of renal artery ste— nosis severity:Stenosis severity<50%had a sensitivity of 100%and a specificity of97.1%:moderate stenosis had a sensitivity of85. 7%and a specificity of 100%:severe stenosis had a sensitivity of 96.2%and a specificity of 90.9%.Conclusions Color Doppler ul- trasound provides a more accurate imaging assistance examinations for the renal artery stenosis;and also provide a more reliable basis to select the appropriate clinical treatment.
