Unruptured aneurysm at the basilar tip (A + B). Due to the broad-based geometry and the unruptured aneurysm status, intrasaccular flow-disruption was envisaged. A WEB SL (7 × 3 mm) was placed within the aneurysm sac, achieving immediate contrast stasis (C). Two-years angiographic control shows complete aneurysm occlusion (D).
