Abstract

The authors analysed 140 cases of subdural hygroma developed after head injury and various neurosurgical operations and was treated at Hanyang university hospital from 1983 to 1989. The results were analysed and summarized as follows. 1) The peak incidence was the age over 50 and under 10. 2) 104 cases(74.4%) were bilateral frontotemporoparietal lesions. 3) Causes were head injury(121 cases), operation for intracranial aneurysms(5 cases), ventriculoperitoneal shunt(5 cases), traumatic(2 cases), external ventricular drainage(1 case). 4) Change in mental status without focal sign of brain damage was presenting symptom. 5) Operation was underwent if 63 cases and the reaccumulation rate was high (26.8%) after trephination but outcome was favorable. 6) Mortality rate in traumatic subdural hygroma was low(5.8%) because brain CT could detect subdural hygroma easily in early stage.
