Abstract

A retrospective study on 107 cases of acute(within 24 hours) subdural hematoma(ASDH) with special reference to the size is presented. The thin ASDH is defined as the hematoma of which thickness is less than 3 mm in the printed CT film(true thickness about 10 mm). 45 cases are the thin ASDH and 62 cases are the not-thin ASDH. Age, Glasgow coma score, pupil, CT finding, operation finding, operation method, interval from injury to CT and operation, and outcome at 1 month are compared and analysed with chi square tests. The most significant difference is the high surgical mortality (92.6%) in the thin ASDH despite of the fact that there are no significant bad prognostic factors. This difference might be due to the fact that diffuse brain injury is more commonly associated with the thin ASDH and suggested that the thin ASDH should be managed differently from the not-thin ASDH.
