Chronic Subdural Haematoma in the CT Scan Era

: One hundred and fifty patients with chronic subdural haematoma were studied with respect to clinical features, investigation and outcome. Those patients aged 65 years and over did not differ significantly in either outcome or clinical features from the rest. The outcome in this series of patients, managed after CT scanning became the standard method of investigation, was no better than in previous studies. The only factor which did influence outcome was the level of responsiveness on admission. The overall mortality in this study was 6 per cent. CT scanning does not therefore result in improved results in patients with chronic subdural haematoma; this may rather depend upon better selection of patients for CT scanning.
