[Qualitative histological diagnostics of the remoteness of traumatic subdural hematomas].

The present histological study was based on the examination of dura mater, capsules, and contents of 200 subdural hematomas (SDH) obtained from the corpses of subjects with a non-penetrating craniocerebral injury within a period from 1 hour to 2.5 years after the trauma. A total of 14 well-reproducible qualitative morphological criteria have been identified for diagnostics of the prescription of subdural hematomas; the probability and the exact earliest and latest times of their manifestation at different dates of the posttraumatic period were calculated. Sensitivity, specificity, and prognostic value of the proposed qualitative morphological criteria for the prescription of traumatic subdural hematomas were evaluated. The results of the study can be used in the practical work of forensic medical experts.
