AbstractThe authors present a series of more than 200 surgical procedures for chronic subdural hematoma in a 5-year-period. Clinical presentation and neurosurgical treatment were regarded with a special focus on the surgical technique. Between March 2003 and July 2008, 193 patients (113 male and 80 female, mean age 72.5 yrs [range 26-97 yrs]) suffering from chronic subdural hematoma were retrospectively analyzed. One-hundred-fifty-one craniotomies and 42 burr holes were performed. Forty-two craniotomy patients (27.8%) in contrast to 6 burr hole patients (14.3%) required surgical revision. A craniectomy was performed as an ultima ratio after at least 2 prior evacuations in 3 cases. Chronic subdural hematoma is a disease of the elderly. A craniotomy seems to possess a higher rate of recurrence of the chronic subdural hematoma so that a burr hole evacuation should be preferred. Craniectomy might be a good therapeutic option in complicated recurrent chronic subdural hematomas.
