Radiological prediction of contralateral extradural haematoma following evacuation of traumatic acute subdural haematoma.

Objectives: To identify radiological predictors of contralateral extradural haematoma (CEDH) in patients undergoing evacuation of acute subdural haematoma (ASDH).

Design: Retrospective case-control study.

Subjects: Patients requiring evacuation of traumatic ASDH via craniotomy/craniectomy with contralateral skull fracture were analysed in two groups: those who developed CEDH postoperatively and those who did not.
