Fifty patients with spontaneous subarachnoid hemorrhage were investigated by both computerized tomography (CT), within 5 days of onset, and complete cerebral angiography. CT showed blood in the basal cisterns in 38 of the 42 patients with a demonstrable aneurysm, but in only 1 of 8 patients with a negative angiogram (p less than 0.001). This means that: (1) blood in the basal cisterns on CT almost certainly indicates a ruptured aneurysm, and (2) unexplained subarachnoid hemorrhages are unlikely to be caused by occult basal aneurysms.
对50例自发性蛛网膜下腔出血患者在发病5天内进行了计算机断层扫描（CT）及全脑血管造影检查。在42例证实有动脉瘤的患者中，38例CT显示基底池内有血液，而在8例血管造影阴性的患者中只有1例CT显示基底池内有血液（P<0.001）。这意味着：（1）CT显示基底池内有血液几乎可以肯定提示动脉瘤破裂；（2）不明原因的蛛网膜下腔出血不太可能由隐匿性基底动脉瘤引起。
