Abstract

The authors analysed 39 cases chronic subdural hematoma admitted to the Department of Neurosurgery, Seoul Red Cross Hospital from January 1990 to June 1993. The results were as follows : 1) The ratio of male versus female was 6.8 : 1 and the incidence was predominant in patients whose ages were over 50. 2) Past history of head trauma was found in 28 cases(72%) and head trauma with habitual alcoholism was found in 6 cases(15%). 3) Symptoms and signs at admission were headache(90%), hemiparesis(62%), mental change(46%) and vomiting(36%). 4) The densities of hematoma shown in Brain CT scan were iso, hypo, mixed, and hyperdense and the shapes of hematoma were crescenteric, planoconvex, and biconvex in order of frequency. 5) We have found an association between the neurologic grade at admission and the prognosis, and noted full recovery in 33 cases(84%) and no death as a result of the 2-burr hole trephination.
