title: Avoidable factors that contribute to complications in the surgical treatment of chronic subdural haematoma.
abstract: The results of a personal series of 44 consecutive patients undergoing burrhole evacuation and closed system suction drainage for chronic subdural haematoma are presented. 43 patients made a complete recovery and one was left with moderate disability. Contralateral weakness in one patient, recurrence of haematoma in another, and a new contralateral haematoma in a third were the only complications. The operative procedures responsible for the rather low complication rate in this series are described. It is concluded that to avoid complications following surgical treatment of chronic subdural haematoma, attention must be paid to the following factors: evacuation of the haematoma through two burrholes overlying the subdural collection; attention to ensure free communication through the subdural space between the two burrholes; identification and opening of additional loculations overlying the cortex; irrigation of the subdural space to ensure as complete an evacuation of the subdural collection as possible and the use of closed system suction drainage, nursing the patient flat, and intravenous hydration of the patient for three days. In addition, in patients with coagulopathy, correction of these disorders before surgery is most essential.
