A, WEB-DL, a double-layer microbraid, used in 37 of the 52 aneurysms in this series. B, WEB-SL, a single-layer implant, used in 15 of the 52 aneurysms in this series.

Ruptured basilar tip aneurysm before (A) and immediately after (B) deployment of the WEB device. After the WEB is placed, no contrast filling can be seen inside the dome, including the bleb that is presumed to be the rupture site; furthermore, there is stasis of contrast inside the WEB beyond the venous phase, indicating sufficient hemodynamic decoupling.
