Abstract:
Lacune is small infarct located in the deeper part of the brain and developed by occlusion of small branch of the large cerebral arteries. It occupies 10-30% of infarction in western countries but 53.1% in our study. We investigated 181 cases of lacunar infarction confirmed by clinical features and neuroimaging study. We analyzed lacunar stroke into 13 groups of symdrome based on the clinical features. The frequent lacunar syndromes were pure motor stroke (35.4%), sensori-motor stroke (26.5%), ataxic hemiparesis (11.6%), and pure sensory stroke (6.1%). The frequent sites for lacune were pons (25.4%), corona radiata (24.9%), and thalamus (18.2%). The major contributing risk factors were hypertension (65.8%) and diabetes (19.3%). The incidence of multiple lacune was 67.4%. The determining factor for clinical presentation of lacune was not the size of lesion but the location of lesion.
