目的:观察彩色多普勒超声检查在肾动脉狭窄诊断中的效能.方法:选取 2022 年 8 月至 2023 年 8 月该院收治的 67 例疑似肾动脉狭窄患者进行横断面研究,所有患者均给予彩色多普勒超声检查与肾动脉造影检查.以肾动脉造影检查结果为"金标准",分析彩色多普勒超声检查诊断结果及诊断效能,同时分析不同狭窄程度肾动脉狭窄患者与肾动脉造影结果的一致性,比较不同狭窄程度肾动脉狭窄患者的彩色多普勒超声检查参数[收缩期峰值流速(PSV)、阻力指数(RI)、舒张末期峰值流速(EDV)、肾动脉峰值流速与腹主动脉峰值流速比值(RAR)]水平.结果:肾动脉造影检查结果显示,67 例疑似肾动脉狭窄患者中阳性 54 例,其中轻度狭窄 20 例,中度狭窄 18 例,重度狭窄 10 例,完全闭塞 6 例;阴性 13 例.彩色多普勒超声检查结果显示,阳性 53 例,阴性 14 例,检查诊断的灵敏度、准确度、特异度分别为 96.30%、95.52%、92.31%,与金标准诊断的一致性好(Kappa值=0.869).彩色多普勒超声检查诊断不同狭窄程度肾动脉狭窄患者与肾动脉造影检查结果的一致性好(Kappa值=0.895).不同狭窄程度肾动脉狭窄患者的EDV、RAR、PSV水平为轻度﹤中度﹤重度或闭塞;不同狭窄程度肾动脉狭窄患者的RI水平为轻度>中度>重度或闭塞,差异有统计学意义(P<0.05).结论:彩色多普勒超声检查在肾动脉狭窄诊断中的效能与肾动脉造影检查诊断的一致性好.
Efficiency of color Doppler ultrasonography in diagnosis of renal artery stenosis
Objective:To observe efficiency of color Doppler ultrasonography in diagnosis of renal artery stenosis.Methods:A cross-sectional study was conducted on 67 patients with suspected renal artery stenosis admitted to the hospital from August 2022 to August 2023.All patients were given color Doppler ultrasonography and renal angiography.Using the results of renal angiography as the"gold standard",the diagnostic results and the diagnostic efficiency of color Doppler ultrasonography were analyzed.At the same time,the consistency between color Doppler ultrasonography and renal angiography in the diagnosis of the patients with different degrees of renal artery stenosis was analyzed.The levels of color Doppler ultrasonography parameters[peak systolic velocity(PSV),interlobar artery resistance index(RI),end-diastolic peak velocity(EDV),ratio of renal artery peak flow/abdominal aorta peak flow(RAR)]in the patients with different degrees of renal artery stenosis were compared.Results:Suspected renal angiography showed that 54 of the 67 patients with renal artery stenosis were positive,including 20 cases of mild stenosis,18 cases of moderate stenosis,10 cases of severe stenosis and 6 cases of complete occlusion,and 13 cases were negative.The color Doppler ultrasonography showed that 53 cases were positive and 14 cases were negative.The sensitivity,the accuracy and the specificity of color Doppler ultrasonography were 96.30%,95.52%and 92.31%.The consistency with the gold standard diagnosis was good(Kappa=0.869).The consistency between color Doppler ultrasonography and renal angiography in the diagnosis of the patients with different degrees of stenosis was good(Kappa value=0.895).The levels of EDV,RAR and PSV in the patients with different degrees of renal artery stenosis were mild<moderate<severe or occlusion;the RI level was mild>moderate>severe or occlusion,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of color Doppler ultrasonography in the diagnosis of renal artery stenosis is in good agreement with that of renal angiography.
