Percutaneous twist-drill craniostomy for the treatment of chronic subdural haematoma.

ABSTRACT

A consecutive series of 65 adult patients with chronic subdural haematoma was reviewed to ascertain the efficacy of twist-drill craniostomy and closed-system catheter drainage. In all patients but two the percutaneous evacuation of the haematoma alone was enough to bring about their recovery. Infections or neurological complications were never observed. Pneumocephalus was likewise absent in all patients. Therefore this technique should be recommended as the "first intention" management of the disease, particularly in elderly patients.
