Abstract
- The authors have experienced 62 cases of chronic subdural hematoma from Jan. 1987 to May 1992 at National Medical Center. In these cases, 58 cases of chronic subdural hematoma were treated with burr hole and closed draninage, 4 cases were managed with conservative management. Male was predominant to female with the ratio of 6:1 and common age was 50-60 years old. Most common causes was head injury and there was cases of chronic subdural hematoma developed after shunt operation. Common symptom was mental change and headache. Brain expansion was delayed in old age group(over 50 years old), Brain CT was available in diagnosis but brain MRI was useful in diagnosis of scantly chronic subdural hematoma. Surgical outcome was related to preoperative neurologic grade and time interval of diagnosis. In this study, clinical improvement rates was 88% in surgically treated cases.
