Clinical imaging correlations in lacunar infarcts

PURPOSE: This paper is a study concerning the clinical-imagistic correlations in lacunar infarcts causes and associated lesions in these ones. We made an attempt to find out and emphasize the risk factors, causes and pathogenic mechanisms involved in lacunar syndromes. MATERIALS AND METHODS: We studied 138 patients with lacunar infarcts diagnosed by clinical examination and computer tomography. The investigation of risk factors evidenced arterial hypertension in 75 cases (54%). The clinical features of lacunar syndromes were: 1) pure motor stroke 41c; 2) pure sensory stroke 8c; 3) ataxic hemiparesis 9c; 4) dysarthria-clumsy hand 1c; 5) sensorimotor stroke 21c; 6) Landry syndrome 1c. RESULTS: We correlated the clinical manifestations and complementary investigations what enabled us to charge in determining of lacunar infarcts: focal microangiopathy-small artery disease (75c), cardio-embolic mechanism (12c), arterio-arteriolar embolic mechanism (15c). The risk factors and pathogenic mechanisms need more adequate research in order to find appropriate prevention and medical attendance.
