Correlation study between small vessel disease and early neurological deterioration in patients with mild/moderate acute ischemic stroke

Aims: Cerebral small vessel disease (SVD) refers to a group of pathological processes that affect small arteries, arterioles, venules, and capillaries of the brain. We hypothesized that imaging markers of SVD could be associated with neurological deterioration during acute phase of mild/moderate ischemic stroke. Methods: We performed a prospective cohort with 687 consecutive patients with acute ischemic stroke and also with admission NIHSS score below 12 points. Imaging markers of SVD include silent lacunar infarction, deep cerebral microbleeds (CMBs), brain atrophy, periventricular and semiovale white matter hyperintensities, basal ganglia and semiovale enlarged perivascular spaces as well as SVD burden rating scale, which were evaluated and calculated, respectively. Early neurology deterioration (END) was defined as an increment of NIHSS score ≥2 points in the first 72 h after admission. Results: None of these imaging markers and rating scale of SVD significantly correlated with END after adjusted for m...
