Abstract
Background and purpose
The Woven EndoBridge is an intrasaccular device for the treatment of intracranial aneurysms. The first generation consisted of a high-profile double-layer braid. This review aims to evaluate the outcomes of the new generation low-profile Woven EndoBridge single layer device for intracranial aneurysm treatment.
Methods
A systematic review was conducted with Medline, Embase, and Web of Science Conference Proceedings databases. The search strategy provided 589 articles, 15 articles were included.
Results
Fifteen articles were identified reporting the use of Woven EndoBridge single-layer devices in 963 aneurysms, mostly wide-necked bifurcation aneurysms. Procedural aneurysm rupture was reported in 8 of 963 patients (0.83%; 95%CI 0.39–1.66%) and thromboembolic events in 54 of 963 patients (5.61%, 95CI 4.31–7.26%). Cumulative morbidity was 2.85% (27/949, 95%CI 1.95–4.12%) and mortality 0.93% (9/963, 95%CI 0.46–1.80%). The overall rate of adequate aneurysm occlusion at last follow-up was 83.3% (613/736; 95%CI 80.4–85.8%). Retreatment was reported in 38 aneurysms in eight studies with 450 aneurysms with follow-up (38/450; 8.4%, 95CI 6.2–11.4%). In 12 studies comprising 644 aneurysms with follow-up, rebleeds occurred in three patients in three studies with mean follow-up between 3.3 and 14.4 months (0.47%, 95%CI 0.09–1.43%)
Conclusion
Woven EndoBridge single-layer is a promising new low-profile device especially for wide-neck bifurcation aneurysms, both ruptured and unruptured. No antiplatelet medication is needed which is a great advantage, especially in ruptured aneurysms. Efficacy and safety compare favorably with (stent-assisted) coiling. However, no direct comparison with other treatments is available as yet.
