- W2388893970 abstract "Objective To evaluate the accuracy of color Doppler ultrasonograpy for diagnosing atherosclerotic renal artery stenosis(ARAS).Methods One hundred and twenty-three patients with atherosclerotic diseases totalling 246 renal arteries were examined by color Doppler ultrasonograpy and renal artery angiography.Both examination were double blind.The ratio of peak systolic velocity (PSV) of the renal artery and abdominal aorta(RAR),intrarenal acceleration time (AT) were obtained.Results For patients with renal artery stenosis ≥50%,the sensitivity and specificity of PSV≥150 cm/s were 80.3% and 98.2%.The sensitivity and specificity of RAR 2.2 were 81.8% and 96.5%.Combined these two criteria,the sensitivity and specificity were up to 96.4% and 94.3%.Intrarenal AT 0.07 s showed the sensitivity and specificity of 90.1% and 91.4% for those with stenosis ≥75%.Conclusions Color Doppler ultrasonography is a reliable and convenient examination for diagnosing ARAS." @default.
