[The comparison of volume of ischemia zone in CT examination with neurological and functional status of patients after cerebral ischemia].

The aim of this work was to establish the correlation between volume of ischemic zone in CT examination and neurological and functional (Barthel index) disorders after cerebral ischemia. The retrospective study was performed. The 30 patients (the median age was 73 years; 14 woman and 16 man) were examined. The medial cerebral artery stroke was recognised in CT. CT examinations without contrast media injection, neurological and functional (Barthel index) diagnostic tests were performed directly and 18 months after ischemia. The evolution of ischemic zone in CT and neurological and functional disorders were estimated. The correlation between volume of ischemic zone in CT, neurological parameters and Barthel index results was examined. The statistical correlation between ischemic zone volumetry and physiological reactions was ascertained. In acute phase the greater volume of ischemic zone responds to neurological dysfunctions. The same tendency, without statistical significance, was observed between volume of ischemic zone and Barthel index result (inversely proportional). 18 months after cerebral stroke the statistical correlation was significant only for comparison of volume of the ischemic zone and Barthel index result. The greater volume of ischemic zone responded to lower Barthel index. Ischemic stroke volumetry in CT examination can facilitate neurological (physiological reactions disorders) and functional (Barthel index) status assessment.
