Clinical Correlates of Doppler/Ultrasound Errors in the Detection of Internal Carotid Artery Occlusion Stroke 20:612-615, Bridgers,S.L., 1989 See this aricle in Pubmed Article Abstract One recognized limitation of carotid Doppler/ultrasound is its accuracy in differentiating occlusion from near-total occlusion of the internal carotid artery,which is a crucial issue in management decisions.Clinical histories were reviewed in 58 patients with apparent occlusion of an internal carotid artery diagnosed by Doppler/ultrasound who also underwent angiography.False-positive results were detected in eight patients,for an overall accuracy of 86%.Among a group of 25 patients with acute cerebral or ocular events ipsilateral to an apparently occluded artery,false- positive results occurred in seven(accuracy of 72%).Among a group of 33 patients with asymptomatic or remotely symptomatic apparent occlusions, only one false-positive occurred,for an accuracy of 97%.This difference in accuracy between groups was significant.Thus,a Doppler/ultrasound diagnosis of occlusion was most inexact in those patients for whom the detection of continued patency was most likely to influence management.
