Case #1: Incidental Basilar tip
aneurysm in a 57-year-old woman
A. Conventional angiography shows a very wide-neck basilar tip aneurysm.
B. Placement of the WEB device within the aneurysmal sac.
C. Angiographic control at the end of EVT shows a small-neck remnant (arrow) that is mostly due to the design of the WEB that has a concave proximal recess.
D. Unsubstracted lateral view at the end of EVT shows the WEB device (arrow).
E. Angiographic control at 12 months shows a stable aneurysm occlusion.
F. Unsubstracted lateral view at 12 months shows the WEB device that remains unchanged both in shape and size (arrow).
G. & H. Show total occlusion of aneurysm at 18 and 24 months, respectively.
