The influence of concomitant intradural pathology on the presentation and outcome of patients with acute traumatic extradural haematoma

Abstract

The pre-operative and early postoperative CT scans of 120 patients who had surgery for acute extradural haematoma were reviewed, 88 cases (73%) had an extradural haematoma alone (Group 1) while 32 cases (27%) had an additional intradural abnormality (Group 2). The abnormalities were a subdural haematoma in eight, a haemorrhagic contusion in 16 and hemisphere swelling in eight. The two groups were compared with regard to the findings that an additional intradural abnormality is likely to be associated with an older age, an injury following a road traffic accident, a GCS less than 7 at operation, additional extracranial injuries and a poorer outcome. The increase in the percentage of patients who were unconscious from the onset and the decrease in those who were always conscious with a concomitant intradural damage was without statistical significance.
