Objective:
We evaluated a prospective cohort of 150 patients under observation in our centre for lacunar strokes. The purpose of this study was to investigate if lacunar stroke of varying size, shape and locations had different risk factors between them and possibly different mechanisms and causes.
Patients And Methods:
150 patients with a lacunar stroke were included in the present study. Infarcts were classified by size, shape and location. We evaluated the correlation between several risk factors of stroke and the radiological characteristics of the infarcts.
Results:
Older age was associated with the presence of a basal ganglia lesion (p < 0.001) and with the presence of a smaller lesion (trend to statistical significance, p = 0.07). Patients with infarcts >15 mm had higher NIHSS score at admission (p 0.01).
Conclusion:
The different subtypes of lacunar infarcts have distinct pathogenesis. Further studies, with a larger numbers of patients, are necessary to confirm our data.
