PREOPERATIVE CT FINDINGS IN EVALUATION OF THE RISK OF RELAPSE OF CHRONIC SUBDURAL HEMATOMAS

Preoperative CT examination of the brain is a necessary diagnostic procedure aiming to establish the diagnosis of chronic subdural hematoma (HSH). The aim of this study was to evaluate the significance of preoperative CT findings in evaluation of the risk of relapse of chronic subdural hematomas. The retrospective analysis of 93 patients who were operatively treated at the Clinic of Neurosurgery in Nis from 2006-2008 was performed.A high level of relapse was shown by the HSHs which at the preoperative CT displayed the characteristics of hyperdensity (11,76%) and mixed-density (28,58%). These results suggest that preoperative CT findings can be considered useful in the evaluation of the risk of HSH relapse. In addition, the preoperative CT findings can help the neurosurgeon in the selection of the operative technique.
