目的 探讨彩色多普勒超声和计算机断层扫描造影(CTA)诊断肾动脉狭窄(RAS)的准确性.方法 将200例患者按有/无RAS分为观察(A,100例)组与对照(B,100例)组,再将A组随机分为超声(A1,70例)组与CTA(A2,30例)组,使用彩色多普勒超声检测A组患者肾动脉血流速度和肾动脉内径,并以肾动脉血流速度和肾动脉内径对RAS的诊断绘制ROC曲线.并使用CTA技术显示A2组患者狭窄的肾动脉血管.结果 ROC曲线示:肾动脉血流速度和肾动脉内径与RAS的关系密切,当肾动脉血流速度＜ 170cm/s、肾动脉内径＜5mm时,受试患者存在RAS.另30例(60支血管)同时进行了肾动脉CTA检查,肾动脉CTA显示的狭窄血管数多于肾动脉造影[45支(75.0％)和41支(68.3％)],差异无统计学意义(P=0.067).结论 彩色多普勒超声诊断RAS的灵敏度和特异性均较高,动脉血流速度和肾动脉内径是监测RAS的有效指标.肾动脉CTA和肾动脉造影具有类似的诊断价值.
目的 探討綵色多普勒超聲和計算機斷層掃描造影(CTA)診斷腎動脈狹窄(RAS)的準確性.方法 將200例患者按有/無RAS分為觀察(A,100例)組與對照(B,100例)組,再將A組隨機分為超聲(A1,70例)組與CTA(A2,30例)組,使用綵色多普勒超聲檢測A組患者腎動脈血流速度和腎動脈內徑,併以腎動脈血流速度和腎動脈內徑對RAS的診斷繪製ROC麯線.併使用CTA技術顯示A2組患者狹窄的腎動脈血管.結果 ROC麯線示:腎動脈血流速度和腎動脈內徑與RAS的關繫密切,噹腎動脈血流速度＜ 170cm/s、腎動脈內徑＜5mm時,受試患者存在RAS.另30例(60支血管)同時進行瞭腎動脈CTA檢查,腎動脈CTA顯示的狹窄血管數多于腎動脈造影[45支(75.0％)和41支(68.3％)],差異無統計學意義(P=0.067).結論 綵色多普勒超聲診斷RAS的靈敏度和特異性均較高,動脈血流速度和腎動脈內徑是鑑測RAS的有效指標.腎動脈CTA和腎動脈造影具有類似的診斷價值.

Objectives Investigate the diagnostic accuracy of the RAS by Color Doppler ultrasound and CTA.Methods Two hundred patients were divided into observation group (A,100) and control group (B,100)according to whether they had/didnt haveRAS.Then divided group A randomly into Group Color Doppler ultrasound (A1,70) and Group CTA (A2,30).Using color Doppler ultrasound detect renal artery blood flow velocity and renal artery diameter of group A.And drew ROC curve of RAS diagnosis on the basis of renal artery blood flow velocity and renal artery diameter level.And use the CTA technique shows patients with renal artery stenosis of A2 group.Results ROC curves revealed:Renal artery blood flow velocity and renal artery diameter is closely related with the RAS.When renal artery blood flow velocity ＜ 170cm/s and Renal artery diameter ＜5mm,Study patients suffering from RAS.While 30 patients(60 vessels) had renal artery CTA,Renal artery CTA display the Number of renal artery stenosis greater than angiography [45 Branch (75.0％) vs 41 Branch (68.3 ％)],The difference was not statistically significant(P =0.067).Conclusions There are have higher sensitivity and specificity Color Doppler ultrasound diagnosis of RAS.Renal artery blood flow velocity and arterial diameter is a valid indicator to monitor RAS.CTA renal artery and renal arteriography have similar diagnostic value.
