Evaluation of controlled digital artery compression in cerebral vascular insufficiency

Abstract

In order to evaluate unilateral digital compression of the carotid artery as a clinical test for the diagnosis of cerebral vascular insufficiency, this maneuver was employed in 280 patients without cerebral vascular insufficiency (CVI) and in 166 patients with CVI. Eeg changes were used as an endpoint. After age 60, the incidence of false positive findings limit the value of this test in clinical diagnosis, but, before this age, a positive response may be useful. Within narrow limits, the location of the major eeg changes may aid in localizing vessels that are insufficient. The procedure is not without risks.
