The ability of four rapid diagnostic testsdirect thermometry, ophthalmodynamometry, and bruit and pulse assessmentto discriminate for the presence or absence of significant extracranial cerebrovascular disease is examined. Utilized separately thermometry, ophthalmodynamometry and the examination for a bruit will find over 75% to 85% of cases. Pulse assessment alone reveals only 40% of significant lesions. The combination of neck examination for the presence of a bruit or pulse deficit alone will discover 93% of the vascular lesions. In the present series 100% of cases were found by including either direct thermometry or ophthalmodynamometry in combination with the aforementioned two tests. Ophthalmodynamometry accurately located the side of the major lesion in more than 90% of the cases. The direct thermometry technique scored below 40% in lesion localization. It is suggested that the thermometry technique, because of the ease of its performance, should be utilized in combination with the neck examination as the preliminary step in assessing patients with suspected extracranial cerebrovascular disease. Ophthalmodynamometry should then be used for more accurate localization of the lesion prior to angiography.
