[Single craniotomy by trephining and closed-circuit external drainage for the treatment of chronic subdural hematoma].
Chronic subdural hematoma is one of the most frequent pathological entities in the adult. Therapeutic approaches have ranged from craniotomy with excision of the membrane to close external drainage placed, under local anesthesia, at the bedside. The authors report the results of treatment of twelve (12) patients by craniotomy with placement of a closed external drainage for the gradual emptying of the chronic subdural hematoma.
