Our experiences in early aneurysm operations: a preliminary report.

Twenty-seven patients affected by ruptured aneurysms and operated on within three days of the first haemorrhage, are presented. At operation 22 patients were graded I-II; a six months follow-up showed a 22% mortality rate. Five patients were graded III-IV at operation and none survived. The results of early operation in our series are examined and discussed. In our opinion it is necessary to know the results of other larger series in order to obtain a final evaluation of early operations on aneurysms.
