We analyzed CT findings of 95 aneurysmal cases taken within 3 days after the onset of SAH and these findings were classified into 3 types, that is, subarachnoid hemorrhage type, intracerebral hematoma type, and intraventricular hematoma type, from the location of the hematoma after aneurysmal rupture. CT findings were scored according to the severity of SAH from 0 to 9 in each types. The relationship between CT score, incidence of symptomatic vasospasm and surgical results was studied and the following results were obtained. (1) CT score correlated well with the severity of clinical grade of Hunt and Kosnik. (2) The cases, in which CT score was above 3, showed high incidence of symptomatic vasospasm high morbidity and mortality. (3) In severe SAH, early operation within 3 days was recommended in the aneurysmal surgery, especially within 24 hours after the onset in cases with CT score (s≥5) and within 3 days in cases with CT score (S≥3). (4) From the above results, CT score may give information for predicting symptomatic vasospasm and deciding the timing of surgery.
