Further understanding of the characteristics of
intracranial atherosclerosis with symptomatic middle
cerebral artery (MCA) steno-occlusion could be helpful
for stroke risk stratification and treatment strategy
modification. This study sought to assess the
association between infarction pattern and size and
intraplaque hemorrhage (IPH) in patients with
symptomatic MCA steno-occlusion lesion. Our key findings
are that 36.8% IPH characterized by SNAP imaging exist
in symptomatic steno-occlusion MCA. In additon, our
findings indicate that IPH together with stenosis may
account for the heterogeneity of infarct sizes and
patterns.
