Age, consciousness level, and temporal lobe involvement on computed tomography scans are key indicators for predicting survival after acute stroke. These factors help evaluate patient prognosis effectively.

Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Cerebrovascular disease diagnosis commonly utilizes computed tomography (CT).
  • Prognostic evaluation of acute stroke patients requires reliable assessment tools.

Purpose of the Study:

  • To assess the utility of cranial computed tomography (CT) combined with neurological assessment for predicting survival in acute stroke patients.
  • To identify specific CT findings indicative of prognosis after stroke.

Main Methods:

  • Prospective study of 245 consecutive acute stroke patients over 1 year.
  • Neurological assessment performed 24-72 hours post-stroke onset.
  • Cranial computed tomography (CT) without contrast administered within the first week of admission; lesions categorized by neuroanatomic regions.

  • Multiple logistic regression analysis used to correlate CT findings and clinical data with survival outcomes.

    • Main Results:

    • Computed tomography (CT) revealed acute lesions in 76% of patients (infarcts) and 11% (hemorrhages).
    • Temporal, parietal, frontal regions, and basal ganglia were the most frequently affected areas.
    • Older age, lower level of consciousness, and temporal lobe involvement were associated with poorer survival rates.

    Conclusions:

    • Age, level of consciousness, and temporal lobe involvement identified via computed tomography (CT) are significant prognostic factors for acute stroke survival.
    • Cranial CT, alongside neurological assessment, provides valuable prognostic information for acute stroke management.
