BACKGROUND: Although twist drill craniostomy for evacuation of a chronic subdural hematoma is a rapid and minimally invasive procedure, it carries the risk of complications because it is a 'blind' technique. Our aim was to analyse the complications in a series of patients treated by this technique in order to identify methods of avoidance by modifications in the surgical technique. METHOD: Thirty-nine patients with a chronic subdural hematoma underwent twist drill craniostomy between November 2002 and December 2005 in our clinic. When a surgical complication happened we modified our surgical technique to see if this avoided it in future patients. FINDINGS: Surgical complications happened in 7 patients (17.9%) including inadequate drainage, brain penetration, acute epidural hematoma and catheter folding. After preventive modifications these complications did not recur. CONCLUSIONS: Modifications in the technique of twist drill craniostomy are described in this paper which may minimise the occurrence of surgical complications.
