PURPOSE: To determine the safety and effectiveness of Guglielmi detachable coils in the endovascular treatment of ruptured and nonruptured basilar tip @entity439 . MATERIALS AND METHODS: A basilar @entity439 was occluded with Guglielmi detachable coils in 21 @entity1 . The aneurysmal diameter was small (less than 12 mm) in 15 @entity1 , large (12-25 mm) in four @entity1 , and giant (more than 25 mm) in two @entity1 . Angiographic follow-up ranged from 6 to 48 months (mean, 26 months); clinical follow-up ranged from 1 to 48 months. RESULTS: Embolization was technically successful in all @entity1 . Complete occlusion was achieved in 14 (67%) @entity1 ; 90% occlusion was achieved in seven (33%) @entity1 . There was partial reperfusion of the @entity439 in three @entity1 (14%) after 6 months, which necessitated repeated embolization. The clinical results were excellent in 13 @entity1 , good in six, and fair in one. One @entity1 died 2 months after the embolization due to @entity358 . A posterior cerebral artery was occluded in five (24%) @entity1 ; one of these @entity1 developed a permanent @entity51 , one developed a transient @entity51 , and three had no clinical symptoms. CONCLUSION: Endovascular treatment of a basilar @entity439 with Guglielmi detachable coils seems to be a safe and less invasive alternative to surgical clipping.
