Abstract

We attemted to clarify the temporal profile and the predisposing factors for progressing neurological disorders in the patients with acute cerebral infarction in the territory of the deep perforators of the carotid system. The subjects were 19 patients with mild hemiparesis admitted to our hospital within 24 hours of stoke onset, and their mean age was 59.9±9.1. Six of those patients (about 32%) had gradual neurological deterioration after admission (progressive cases), and they had poor outcome compared with non-progressing patients. The mean progressing period was 3.7±1.0 days. Our examination suggest that both the changes in systemic hemodynamics and the risk factors for cerebrovascular disease (hypertension, diabetes mellitus, hyperlipidemia) do not always provide a correlation with the development of progressing stroke. However, we speculate that the impairment of the microcirculation plays a major role in progressing stroke in the territory of penetrating arteries because of the result that the mean infarct size of progressive patients had a tendency to be larger than that of non-progressive patients in the chronic stage.
