Recurrent aneurysmal subarachnoid haemorrhage: incidence, timing and effects. A re-appraisal in a surgical series.
A series of 510 patients with proven aneurysmal subarachnoid haemorrhage (SAH) is reported. The incidence of recurrent haemorrhage during the period awaiting surgery was 13.7%. There was no significant difference in incidence between good and poor grade patients. Following rebleeding there was an immediate mortality of 34% in good grade patients and 52% in poor grade patients. In the long term only 44.4% of good grade and 8% of poor grade patients made a good recovery following a second bleed as compared to 70.6% and 52.8% respectively for those who did not rehaemorrhage.
