Abstract

The color coded continuous wave doppler ultrasound was compared with angiography in 201 arteries, 83 with greater than 50% diameter stenosis and 118 with less than 50% stenosis. Overall accuracy in identifying hemodynamically significant (greater than 50% diameter stenosis) was 87% in the presence of peak velocities greater than 5000 Hz and a blue color coded image. Negative predictive value was 94.5%. False positives were mainly due to the presence of severe external carotid stenosis and increased flow due to contralateral carotid occlusion. Within the limitations of the test being an indirect method, it is a reliable screening method for detecting hemodynamically significant carotid artery disease.

摘要

对201条动脉进行了彩色编码连续波多普勒超声与血管造影的比较，其中83条动脉直径狭窄超过50%，118条动脉直径狭窄小于50%。在峰值速度大于5000Hz且图像为蓝色编码的情况下，识别血流动力学显著（直径狭窄超过50%）的总体准确率为87%。阴性预测值为94.5%。假阳性主要是由于存在严重的颈外动脉狭窄以及对侧颈动脉闭塞导致血流增加。在该检测作为间接方法的局限性范围内，它是检测血流动力学显著的颈动脉疾病的可靠筛查方法。
