Variability of Vascular Territory in Stroke:Pitfalls and Failure of Stroke Pattern Interpretation Stroke 26:942-945, Lang,E.W.,et al, 1995 See this aricle in Pubmed Article Abstract Classification of infarction patterns resulting from carotid stenosis was independent of the territorial extension map chosen:83#were classified as territorial.Classification of patterns due to carotid occlusion,however, varied highly;81%of infarctions were considered territorial when the maximal middle cerebral artery distribution map was used,whereas only 19% were when the minimal territorial extension map was used.The current concept that stroke mechanisms can be inferred from the interpretation of stroke patterns seen on computed tomography scans or magnetic resonance imaging is significantly confounded by the demonstrated variability in intracranial vascular distributions.Stroke pattern interpretation appears to be highly dependent on the in vivo vascular tree of the individual, which is unknown to the examiner.This calls into question the reliability of classifying infarction patterns as border-zone or territorial. Determination of true underlying stroke mechanisms requires a comprehensive approach and cannot be based solely on stroke pattern interpretation.
