A) Wide-necked basilar tip aneurysm, with height of 14 mm. B) As the aneurysm height exceeded the maximum available height of the WEB II, 2 coils were positioned within the aneurysm after WEB II deployment. This combined technique was described by Pierot et al. (see text for details) and appeared safe and effective. C) DSA performed 9 months after treatment shows complete exclusion of the aneurysm from the intracranial circulation and normal patency of the posterior cerebral arteries.
