Repeat CT scanning and cerebral angiography has been performed in 68 consecutive patients with subarachnoid hemorrhage. Blood in the subarachnoid cisterns could be discerned in 27 of 32 patients provided the examination was performed within 2 days of the bleeding. The distribution of cisternal blood can be identified which, in combination with the localization of a possible intracerebral hematoma, yields a rather good predictability as to the site of the ruptured aneurysm. The subsequent angiography can thus be directed to the relevant vessel in most cases. Repeat CT scanning can replace angiography in the evaluation of patients with deterioration of the clinical condition.
对68例连续的蛛网膜下腔出血患者进行了重复CT扫描和脑血管造影。如果在出血后2天内进行检查，32例患者中有27例可在蛛网膜池内发现血液。可以确定脑池内血液的分布，结合可能存在的脑内血肿的定位，对破裂动脉瘤的部位有相当好的预测性。因此，在大多数情况下，后续的血管造影可以针对相关血管进行。在评估临床病情恶化的患者时，重复CT扫描可以替代血管造影。
