Recently published data from the International Subarachnoid Aneurysm Trial (ISAT) shows that for patients enrolled in the trial there is a 7.4% reduction in the incidence of death or dependency at 1 year if they undergo coiling, rather than clipping. Furthermore, extrapolation of longer-term follow-up data for patient mortality appears to suggest that this advantage will be maintained in the longer term. ⋯ Treatment of aneurysms is a continually evolving field and there is currently no other major source of information concerning management of aneurysms. For these reasons the authors recommend the instigation of a national aneurysm registry to prospectively collect data.
