[Experiences in diagnosis and treatment of chronic subdural hematoma]

Abstract

Diagnosis and treatment of 95 patients with chronic subdural hematoma (CSDH) are presented. There were 92 males, 56 patients (59%) over 51 years old and 66 of them with history of head injury. The majority of our patients appeared increased intracranial pressure. Mental confusion and incontinence of urine and stool usually occurred in senile patients. Ultrasonic and electroencephalography examination were helpful in location of the hematoma. Cerebral angiography could make actual diagnosis. CT scan were more useful in diagnoses of CSDH and may discover multiple hematomas. If CSDH image were iso-dense on CT scan cerebral angiography should be performed. In the early years extirpation of CSDH including the capsule was performed. Now an irrigation drainages by cranial bur hole was performed usually. 5 patients had complication. The mechanism and prevention of CSDH are discussed.
