[Early surgery of ruptured aneurysms. A factor in preventing ischemia]

110 patients with ruptured aneurysms were operated on within 4 to 96 hours after subarachnoid hemorrhage. Clinical grades (Hunt) were: 1-2-3 in 93 cases and 4-5 in 17 cases. Among the patients grades 1-2-3, 81% had a good out come without any neurological abnormality, among the patients graded 4-5, only 27% had a fair out come. Cerebral ischemia has been noted (CTS can + neurological deficits) in 7 cases only among patients graded 1-2-3 (93 cases). The results, concerning ischemia, are better than the natural course of ruptured aneurysms and better than the course in series with delayed operation. Probably vasospasm is not alone to create ischemia.
