[Surgical outcome in chronic subdural hematoma].

In a retrospective study the operative results of 200 patients with chronic subdural hematoma were investigated. In the majority of patients a burr hole and a closed drainage was performed. The operative result was very good (resumption of normal life) in 67.5% of the patients. Operative mortality was 4.5%, in these patients an obvious connection was appearant between the result and the poor preoperative condition. The recurrence of hematomas required a second operation in 8% and a third in 1%.
