Follow-up scheme of 154 patients with a basilar tip aneurysm.

A 41-year-old man with a coiled ruptured basilar tip aneurysm in 1997 and a rebleed 15 years later. A, Angiography in 2006, 9 years after coiling in 1997, shows an adequately occluded basilar tip aneurysm. B, CT in 2012 demonstrates a rebleed from the basilar tip aneurysm. C, Angiography reveals regrowth of the aneurysm (arrow). D, After additional coiling, the aneurysm is completely occluded (arrow).

Timing of first retreatments in 37 patients with reopened basilar tip aneurysms.

Timing of retreatments in 15 patients with coiled basilar tip aneurysms and >1 recurrence.

Serial MR images of a 40-year-old man with a coiled ruptured basilar tip aneurysm in 2003. A, Transversal T2-weighted MR image from December 2003 shows a basilar tip aneurysm 6 months after coiling. B, MR imaging in May 2008 shows enlargement of the aneurysm and compression of the brain stem. C, MR imaging in March 2009 shows further growth, now with edema in the brain stem. D, MR imaging in December 2009 shows a rapid increase in size with enormous compression of the brain stem. The patient died 1 month later.
