BACKGROUND AND PURPOSE: Endovascular coiling is an alternative to surgical clipping for ruptured @entity438 . However, no large multicenter prospective study has compared coiling and clipping in @entity1 with poor-grade @entity1756 . We aimed to determine differences in @entity260 and clinical outcome between the 2 treatments in this group of @entity1 . MATERIALS AND METHODS: A Multicenter Poor-Grade @entity439 Study was a prospective, multicenter, observational registry of consecutive @entity1 who presented with poor-grade @entity1756 . Three hundred sixty-six @entity1 were enrolled from October 2010 to March 2012. "Poor-grade @entity439 " was defined as a World Federation of Neurosurgical Societies grade of IV or V at the time of @entity439 treatment. Two hundred sixty-two @entity1 received @entity439 treatment within 21 days and were included. Clinical outcomes were assessed at discharge and at 6 and 12 months by the modified Rankin Scale. RESULTS: One hundred thirty-three (50.8%) @entity1 underwent endovascular coiling. Unadjusted analysis showed that the outcome rate (mRS 0-1 or mRS 0-2) at 6 and 12 months in @entity1 undergoing coiling was higher than that in @entity1 undergoing clipping. In adjusted analyses, there was no statistically significant difference in outcomes at 6 and 12 months between the 2 groups. The risk of radiologic @entity1276 was higher in @entity1 treated with coiling than that in those treated with clipping (adjusted OR, 3.36; 95% CI, 1.13-10.01; P = .030). CONCLUSIONS: The long-term outcome in selected @entity1 was similar between endovascular coiling and clipping for poor-grade @entity1756 . The risk of radiologic @entity1276 was higher after endovascular treatment of poor-grade @entity439 .
