Abstract
Background
The Woven EndoBridge (WEB) has been specifically developed to manage wide neck bifurcation intracranial aneurysms. A wide range of aneurysm occlusion rates and device-related complications are reported in different papers, and a lack of collective evidence in this regard.
Objective
To clarify the long-term efficacy and safety outcomes of intracranial aneurysm treatment with WEB devices.
Methods
A systematic literature search was performed on PubMed, Scopus, Web of Science, and Embase databases on April 25, 2023. Considering the eligibility criteria, all the studies reporting the outcomes of the intracranial aneurysm treatment with WEB device at 1 and/or more than 1 year were included. Data elements of interest were extracted and analyzed using R software version 4.2.1.
Results
Twenty-seven articles were included. Complete occlusion rate was 56.85%, 67.10%, and 56.34% at one year, beyond one year, and at/beyond two years of follow-up, respectively. Adequate occlusion rate was 87.11% at one year, 91.16% beyond one year, and 88.87% at/beyond two years of follow-up. WEB compression and aneurysm recurrence rates increased from 17.62% and 0.58% at one year to 42.59% and 18.99% beyond one year of follow-up, respectively. An increase in retreatment rate from 3.45% at one year to 7.15% beyond one year of follow-up was found.
Conclusion
The current study supports the long-term efficacy of WEB devices for the treatment of intracranial aneurysms. However, an increase in WEB compression, aneurysm recurrence, and retreatment rates beyond one year reveals the importance of follow-ups after the first year of WEB placement.
