Stenosis

The relationship between different distribution patterns of cerebral infarcts and the presence of internal carotid artery (ICA) or middlecerebral artery (MCA) stenosis has been studied with inconsistentresults. In summary, the occurrence of acute/ early subacute middle cerebral artery infarcts in the shower/corticalwatershed/superficial perforating territory distribution is stronglyassociated with the presence of critical stenosis of the internal carotidartery or the first segment of the middle cerebral artery. The primary objective of this study was to compare the presence ofcritical stenosis of either the ipsilateral ICA or the M1 segment of theipsilateral MCA between the two study groups (SWPs vs. MTPd). Thedegree of stenosis on MRA was measured according to the NorthAmerican SymptomaticCarotid Endarterectomy Trial (NASCET)Criteria. Comparing the presence of either ipsilateral ICA or M1 criticalstenosis between the two study groups showed a strong statisticalsignificance towards a higher frequency of critical stenosis in thegroup composed of cortical-predominant multifocal, corticalwatershed, and superficial perforating territory infarcts (P=.001). Thisdifference persisted on the logistic regression analysis even after weadjusted for age, sex, hypertension, diabetes mellitus,hypercholesterolemia.
