THE VALUE OF DIFFERENT METHODS OF TREATMENT OF BRAIN-ABSCESS IN THE CT ERA

67 cases of brain abscess were analyzed retrospectively. As 2 comatose patients died on admission before any treatment was started, the results are based on 65 treated patients. Different methods of treatment included: total removal in 36 patients, drainage in 14, aspiration in 6 and conservative treatment in 9. Management mortality was 18,5% and was almost not dependent on the method of treatment (except aspiration) being lowest in the drainage group. The mortality was significantly higher in patients with serious impairment of consciousness on admission. Follow-up examination after 1 to 11 years was performed in 47 out of 53 discharged patients and revealed in 25 of them (53%) full recovery. 10 additional cases (21%) are independent. The best early and long term results were obtained in patients by drainage and medical treatment. Chronic epilepsy developed in 34% of patients with supratentorial lesions. The risk of epilepsy was lowest in the group of patients treated by drainage. The authors present the opinion that removal of brain abscess is necessary only in exceptional cases. © 1990 Springer-Verlag.
