A noninvasive cerebrovascular evaluation has been devised that combines three separate but complimentary procedures: ocular pneumoplethysmography (OPPG), carotid audiofrequency analysis (CAA), and cerebral Doppler analysis. This evaluation has proven particularly useful in examination of the asymptomatic carotid bruit, and the management of such patients is aided by noninvasive testing. Patients with a poorly compensated stenosis (reduced OPPG) are all considered candidates for angiography and surgery. For patients with a well-compensated (normal OPPG) but surgically important stenosis (abnormal CAA or Doppler), angiography and surgery are recommended in selected patients. Angiography and/or surgery are believed safely withheld in all remaining patients. The reliability and effectiveness of this approach is evaluated in a series of 100 consecutive patients with an asymptomatic carotid bruit. There were no false-positive results and only known false-negative interpretation.
已设计出一种非侵入性脑血管评估方法，它结合了三种独立但互补的程序：眼体积描记法（OPPG）、颈动脉音频分析（CAA）和脑多普勒分析。这种评估在无症状颈动脉杂音检查中已证明特别有用，非侵入性检测有助于此类患者的管理。狭窄代偿不良（OPPG降低）的患者均被视为血管造影和手术的候选者。对于代偿良好（OPPG正常）但具有手术重要性狭窄（CAA或多普勒异常）的患者，建议对部分患者进行血管造影和手术。所有其余患者被认为可安全地不进行血管造影和/或手术。在一系列连续100例无症状颈动脉杂音患者中评估了这种方法的可靠性和有效性。没有假阳性结果，只有已知的假阴性解读。
