Benign Outcome of Carotid Occlusion Neurol 39:6-8, Borenstein,N.M.&Norris,J.W., 1989 See this aricle in Pubmed Article Abstract We followed 40 patients with unilateral carotid occlusion by serial clinical and Doppler evaluation for over 6 years.Two groups were identified:19 patients had already occluded their arteries on entry to the study,and 21 progressed to occlusion during the course of the study.No strokes occurred in the first group during follow-up,and the annual stroke rate in the second group was 3.8%for the territory of the occluded artery and 5.7%for all vascular territories.Death rate was 6.6%annually for both groups,mainly cardiac.Transcranial Doppler with digital compression of each carotid artery demonstrated middle cerebral artery(MCA)dependency on the patent carotid being total in 50%and partial in 30%.There was no correlation between degree of stenosis and MCA dependency(r=-0.24).Our data on stroke risk in asymptomatic patients with unilateral carotid artery occlusion indicate a benign outcome.
