WEB-DL Endovascular Treatment of Wide-Neck Bifurcation Aneurysms: Short- and Midterm Results in a European Study

Abstract

BACKGROUND AND PURPOSE:Flow disruption with the WEB-DL device has been used safely for the treatment of wide-neck bifurcation aneurysms, but the stability of aneurysm occlusion after this treatment is unknown. This retrospective multicenter European study analyzed short-and midterm data in patients treated with WEB-DL.

Intrasaccular Flow Disruption in Acutely Ruptured Aneurysms: A Multicenter Retrospective Review of the Use of the WEB

“…In nonruptured aneurysms, the WEB has been described in a number of published series to be both safe and efficacious. [12][13][14] Because of its conceptual difference from standard coil occlusion, a potential yet unproven advantage of the WEB is faster hemodynamic separation of the aneurysm; immediate stasis is often seen after its deployment (Fig 2). The absence of overlapping radiopaque material might enable accurate positioning at the level of the neck, even in broad-based aneurysms.…”

“…It seems to be especially suitable for broad-based bifurcation aneurysms and may eliminate the need for other reconstructive measures inside the parent artery, such as placing a stent. 12 Numerous publications have described the successful use of the WEB in the treatment of unruptured wide-neck bifurcation aneurysms. [12][13][14] Just recently, a single-center experience with the WEB in 6 ruptured aneurysms was reported, and the results were promising.…”

Flow-Diverter Stents for the Treatment of Saccular Middle Cerebral Artery Bifurcation Aneurysms

“…Some midterm follow-up studies have been published 17,31,32 and show good safety with morbidity rates of between 1.3% and 3.1%, with no mortality reported. Midterm anatomic results 17,31,33 have shown complete occlusion in 26.7%-56.9% of aneurysms.…”

WEB Treatment of Intracranial Aneurysms: Feasibility, Complications, and 1-Month Safety Results with the WEB DL and WEB SL/SLS in the French Observatory

“…The initial clinical results have shown that treatment is feasible with a low level of complications, low morbidity, and no mortality.
