Mean treatment time with FD was 5.8 d (range, 0-11 d) from ictus. The technical success rate was 100%. On admission 2 patients were Hunt and Hess grade 1, 2 patients grade 3, and 1 patient grade 4. At discharge, 4 patients (80%) were independent (modified Ranking Scale (mRS)\u00a0\u22642) and 1 patient had severe disability (mRS 4). None of the patients had aneurysmal rebleeding. All 5 aneurysms were completely occluded on angiographic follow-up (range, 3-22 mo). One patient had permanent intraprocedural in stent thrombosis and brain infarction. One patient had spontaneous nonaneurysmal intracerebral hemorrhage 1 mo after FD treatment.
