Management of Recurrent Subdural Hematomas

摘要: Subdural hematomas commonly recur after surgical evacuation, at a rate of 2% to 37%. Risk factors for recurrence can be patient related, radiologic, or surgical. Patient-related risk include alcoholism, seizure disorders, coagulopathy, and history ventriculoperitoneal shunt. Radiologic poor brain reexpansion postoperatively, significant subdural air, greater midline shift, heterogeneous (layered multi-loculated), higher-density hematomas. Surgical lack postoperative drainage. Most recurrent are managed successfully with burr hole craniostomies closed-system Refractory may variety techniques, including craniotomy subdural-peritoneal shunt placement.
