Technical aspects of web device in aneurysm treatment.

Wide-neck bifurcation aneurysms (WNBAs) make up 26-36% of all brain aneurysms. Intrasaccular flow disruption is an innovative technique for the treatment of WNBAs. The Woven EndoBridge (WEB) device (Sequent Medical, Aliso Viejo, California USA) is the only United States Food and Drug Administration approved intrasaccular flow disruption device. In this video article, a few cases of intracranial aneurysms treated with the WEB device are presented and various aspects of treating WNBAs with the WEB device, including aneurysm/device selection strategies, and procedural technique, are discussed (video 1).
