Summary:Since the introduction of computerized tomography (CT) it has been possible to trace the image of the brain after removal of subdural haematoma. Postoperative studies demonstrated often presence of residual haematoma. This raises the problem of establishing indication to reoperation, especially of patients with good clinical condition. The clinical condition and CT images before and after operation were assessed in 20 patients treated surgically for chronic subdural haematoma. A statistically significant correlation was found between the magnitude of the effect of the space occupying lesion in CT image and the severity of the clinical condition. A high-grade mass effect with major ventricular system shifting was more often connected with presence of partly haemolysed haematoma in CT. Subdural haematoma thickness exceeding 20 mm correlated with serious clinical condition of the patient, and increased the likelihood of hemiparesis persisting after the operation. Finding of residual haematoma in postoperative CT should not be an indication to reoperation, if not associated with high-grade mass effect and if the clinical condition is good. In our material out of 15 patients with good clinical condition postoperatively residual haematoma was detected by CT in 12 cases, but only one had to be reoperated because of persistent high-grade mass effect.
