Chronic Subdural Hematoma

Abstract

AFTER evacuation of a subdural hematoma the compressed hemisphere may fail to expand spontaneously. This may be a grave prognostic sign. Trotter,¹ Coleman,² Coblentz³ and Voris⁴ have discussed this aspect of subdural hematoma.We agree with Coleman and Coblentz that failure of the compressed hemisphere to expand is more likely than cerebral edema to cause serious symptoms. Coleman found that the compressed hemisphere may not expand for several days after evacuation of the clot. It has been shown that the hemisphere may still be in a compressed state at autopsy even though the hematoma has been adequately evacuated.⁵ We have . . .
