To determine the value of Doppler periorbital flow measurements (DOP) and real-time ultrasonic in the analysis of carotid artery occlusive disease, 1,203 carotid arteries were evaluated in 669 consecutive patients from 1 June 1980 to 1 July 1981. The results of DOP and US were compared with biplane carotid arteriograms using the Seldinger technique. The stenoses were graded: Grade I (zero to 25 per cent), Grade II (25 to 50 per cent), Grade III (50 to 75 per cent) and Grade IV (75 to 100 per cent). Both US and CA agreed in 71.3 per cent of 209 arteries. US and DOP were performed together in 1,203 arteries and agreed in 83.2 per cent. The flow surfaces of an additional 29 arteries were visually inspected at operation to determine the capacity of US to predict ulceration. All of the arteries demonstrated visible ulceration, but only six (20.7 per cent) were predicted by US. The deepest ulcerations that were not detected by US were 2 millimeters in depth. US images were unsatisfactory in 44 arteries (3.7 per cent) because of excessive sound reflection and in 60 (5.0 per cent) because of a "high bifurcation." We conclude that Doppler periorbital flow studies are not as accurate as carotid sonography nor do they add to the accuracy of sonography when the two examinations are combined. Sonography identified significant stenoses but failed to grade the stenoses well and was unreliable in detecting shallow to moderately deep ulcerations.
为确定眶周血流多普勒测量（DOP）和实时超声检查在分析颈动脉闭塞性疾病中的价值，于1980年6月1日至1981年7月1日对669例连续患者的1203条颈动脉进行了评估。将DOP和超声检查的结果与采用Seldinger技术的双平面颈动脉血管造影结果进行了比较。狭窄程度分为：I级（0至25%）、II级（25至50%）、III级（50至75%）和IV级（75至100%）。在209条动脉中，超声检查和血管造影结果一致的占71.3%。对1203条动脉同时进行了超声检查和DOP检查，二者结果一致的占83.2%。另外29条动脉在手术中进行了肉眼检查以确定超声检查预测溃疡形成的能力。所有这些动脉均显示有明显溃疡形成，但超声检查仅预测出6条（20.7%）。超声检查未检测到的最深溃疡深度为2毫米。44条动脉（3.7%）的超声图像因回声反射过多而不满意，60条动脉（5.0%）因“高位分叉”而不满意。我们得出结论，眶周血流多普勒研究不如颈动脉超声检查准确，且在两项检查联合应用时也不会提高超声检查的准确性。超声检查可识别出明显狭窄，但对狭窄程度分级不佳，在检测浅至中度深度的溃疡方面不可靠。
