Incidental 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).

Incidental aneurysm in a 58-year-old woman. A, 3D angiography shows a wide-neck MCA trifurcation aneurysm. B, EVT was performed and resulted in a WEB protrusion within a branch; IV abciximab was administered and a Solitaire stent (arrow) was placed, achieving an incomplete occlusion and patency of the stented branch. C, Angiographic control at 6 months shows a stable small-neck remnant.

Incidental aneurysm in a 64-year-old woman. A, Conventional angiography shows a 13-mm basilar tip aneurysm with a 5-mm neck. B, Angiographic control at the end of EVT shows an incomplete aneurysm occlusion. C, Angiographic control after complementary treatment by stent-assisted coiling shows a complete aneurysm occlusion.
