This is a comparative study of the blood distribution in computer cranial tomograms after spontaneous subarachnoid hemorrhage in 51 patients with saccular aneurysms and 34 patients with no evidence of a source of bleeding in cerebral panangiography. There was often less blood observed at all sites when aneurysms were not present. This was, however, significant only in the interhemispheric fissure, the Sylvian cisterns, the parietal sulci as well as intracerebrally. Thus, 79.4% of patients without an aneurysm were in grades I and II of the Hunt and Hess scale as opposed to 47.0% of those patients with evidence of an aneurysm.
这是一项对比研究，针对51例囊状动脉瘤患者和34例脑血管造影未发现出血源证据的患者，观察自发性蛛网膜下腔出血后计算机头颅断层扫描中的血液分布情况。当不存在动脉瘤时，在所有部位观察到的血液通常较少。然而，这仅在大脑半球间裂、外侧裂池、顶叶脑沟以及脑内具有显著意义。因此，79.4%无动脉瘤的患者处于Hunt和Hess分级的I级和II级，而有动脉瘤证据的患者中这一比例为47.0%。
