The supraorbital Doppler technique was used to study 102 carotid arteries prior to arteriography. A carotid stenosis was defined as being hemodynamically significant if the diameter of the lumen were reduced by more than 50 percent. The Doppler examination gave a false-positive result in only two of the 61 arteries which did not demonstrate significant stenoses. False-negative Doppler results occurred in 22 percent of the 41 significant carotid lesions. The presence or absence of significant carotid lesions were predicted in 96 percent of 67 arteries for which the results of the supraorbital examination and carotid auscultation were in agreement. False-negative results occurred in association with significant ipsilateral external and common carotid stenoses and in the presence of unusually efficient collateral circulation via the circle of Willis. The supraorbital Doppler examination is a valuable technique for the identification of patients with hemodynamically significant carotid stenoses.
在进行动脉造影之前，采用眶上多普勒技术对102条颈动脉进行了研究。如果管腔直径缩小超过50%，则将颈动脉狭窄定义为具有血流动力学意义。在61条未显示明显狭窄的动脉中，多普勒检查仅出现了两例假阳性结果。在41处具有血流动力学意义的颈动脉病变中，22%出现了多普勒检查假阴性结果。对于67条眶上检查结果与颈动脉听诊结果一致的动脉，96%可预测有无具有血流动力学意义的颈动脉病变。假阴性结果与同侧颈外动脉和颈总动脉明显狭窄以及通过 Willis 环存在异常有效的侧支循环有关。眶上多普勒检查是识别具有血流动力学意义的颈动脉狭窄患者的一项有价值的技术。
