- FIG 1.
Ruptured anterior communicating artery aneurysm treatment using an SL 3.5 × 2 mm WEB. A, Left internal carotid angiogram shows the aneurysm. B, 3D rotational angiography with aneurysm measurement. C, A postdeployment angiogram shows a good filling of the aneurysmal sac with persistent opacification inside the WEB. D and E, Three-month follow-up angiogram shows complete exclusion of the aneurysm. F, Three-month follow-up VasoCT confirms the aneurysm exclusion, with slight WEB compaction.
- FIG 2.
Technical failure in a left superior cerebellar artery with an SL 3 × 2 WEB. A, A left vertebral angiogram shows the left cerebellar aneurysm. B, 3D rotational angiography with aneurysm measurement. C, WEB deployment attempt, with the proximal marker (white arrow) protruding into the basilar trunk. D, Final angiogram after coiling. E, Retrospective Sim&Cure simulation showing SL 3 WEB protrusion into the superior cerebellar artery and basilar trunk.
