Chronic subdural haematoma: a review of 114 cases.

One hundred and fourteen consecutive adult patients treated surgically for chronic subdural haematoma are described and their clinical features presented in detail. The diagnostic investigations are evaluated and a regime of surgical management is described. The three main modes of clinical presentation and the diagnostic role of carotid angiography are emphasised. It is suggested that the neurological state at the time of operation has no bearing on the prognosis and that, in particular, patients presenting in coma have a much better prognosis than might be expected. The average follow-up period was two years and the longest 11 years.
