Abstract:
A series of 70 patients with chronic subdural hematoma, admitted to the Department of Neurosurgery of Kyung Hee University Hospital from Aug. 1, 1977 to July 31, 1982 is presented. The following results were obtained. 1) Males were more frequently involved than female with the ratio of 4.8 : 1. Peak age incidence was 6th and 7th decade. Bilateral subdural collections were only 4 cases and others were unilateral. 2) Older age(more than 50) had more frequently focal neurologic deficit such as hemiplegia, however younger age(less than 50) presented as increased intracranial pressure signs such as headache and vomiting. 3) The hematoma density of CT-scan on admission was hypertense, 3 cases(4.9%); mixed density, 20 cases(32.8%); isodense, 18 cases(29.8%); and hypodense, 20 cases(32.8%) respectively. 4) The operative method between simple burr hole drainage and craniotomy with membranectomy didn't affect the postoperative results. The operative mortality was 2.9%. 5) Follow-up CT scanning was performed in 32 patients, only 8 of them showed normal CT findings within one month after operation. One patient still showed remnant of hematoma on 50th postoperative day. 6) Osmolarities of the hematoma and systemic venous blood were measured simultaneously 10 times in 8 cases. Hematoma osmolarities were isosmolar 1, hyperosmolar 6 and hyposmolar 3 compared with systemic venous blood.
