Blood distribution in computer cranial tomograms after subarachnoid hemorrhage with and without an aneurysm on
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.
