| ABSTRACT |
|
We have done clinical analysis of 92 cases with chronic subdural hematoma, admitted to our department from August 1, 1984 to July 31, 1987. The following results were obtained; 1) The ratio of male versus female was 3.6:1, and 6 cases(71.7%) were over 50 year-old age. 2) 50 cases(75.7%) in older group(over 50) had head trauma history, and 11 cases(42.3%) in younger group(under 50). 3) The major clinical symptoms and signs in older group were mental deterioration and hemiparesis, in younger group headache and vomiting. 4) The hematoma densities in CT on admission were hyperdense 1.0%, isodense 33.7%, hypodense 39.3%, and mixed 25.9%. The shapes were biconvex 45.7%, planoconvex 35.8%, and crescenteric 18.5%. 5) The operation method was either burr hole drainage, or craniotomy with membranectomy, according to patient's physical condition and CT findings.
In postoperative results there was no significant difference in both. |
