title: GDC in ruptured versus unruptured aneurysms.
abstract: We have treated 581 aneurysms in 510 patients from August 1990 to November 1998. In 247 patients the presentation was acute rupture. In 141 patients the aneurysm treated was incidental. Complications in the acute group was 10.1% morbidity with 2.8% procedure related mortality. The corresponding rates were 4.2% and 0% in the incidental group. In the incidental group all complications occurred up to 1995. In our last 91 patients there has been no morbidity or mortality. Anatomic outcomes were dependent upon aneurysm geometry in both groups. This low rate of complications when compared to the natural history for both ruptured and unruptured aneurysm favors treatment if the long-term follow-up confirms reduced longitudinal hemorrhage rates, and the aneurysm has a favorable geometry.
