[Prognostic significance of early CT changes in ischemic stroke patients].
The aim of the study was to establish the prognostic value of early CT findings in predicting the 30-day mortality after stroke, to assess the prevalence of these findings in acute stroke patients, and to examine the correlation between these findings and the clinical status. 134 patients (mean age 67.5 +/- 12.1) with supratentorial ischaemic stroke and CT performed within 12 hours from onset of the symptoms were included into the study. The neurological deficit and consciousness disturbances were assessed by means of Scandinavian Stroke Scale. The 30-day mortality was registered. CT findings were found in 84 (63.7%) patients, including hypodense lesions in 74 (55.5%), mass effect in 55 (41.0%) and hyperdense middle cerebral artery sign in 5 (3.7%) cases. Patients with mass effect had greater neurological deficit on admission (p < 0.0001), more frequently developed disorders consciousness (p = 0.001) and had greater 30-day mortality (p < 0.0001). Patients with hypodense lesions of at least two types presented with greater neurological deficit observed on the second day of hospitalization (p < 0.05) and had also greater 30-day mortality (p = 0.01). On multivariate analysis mass effect seen in early CT, as well as older age and greater neurological deficit appeared to be independent predictors of 30-day mortality.
