Natural History of Stenosis from Intracranial Atherosclerosis by Serial Angiography Stroke 29:433-438, Akins,P.T.,et al, 1998 See this aricle in Pubmed Article Abstract We identified 21 patients with 45 intracranial stenoses who underwent repeat angiography at an average interval of 26.7 months.The average stenosis for all intracranial lesions was 43.9%initially and 51.8%on follow-up(P=.032).The average stenosis in the intracranial internal carotid artery(ICA)was stable(51.2%versus 52.6%).The average stenosis in the anterior cerebral artery(ACA),middle cerebral artery(MCA),and posterior cerebral artery(PCA)progressed from 32.4%to 49.7%(P=.037).Based on a minimum of 10%change,20%of intracranial ICA lesions progressed compared with 61%of ACA,MCA,and PCA lesions.Regression occurred in 14%of the intracranial ICA group and 28%of the ACA-MCA-PCA group.Cerebrovascular events were infrequent during this period,with 4 transient ischemic attacks and 1 intracerebral hemorrhage.
