Long-Term Follow-up of the Woven EndoBridge (WEB) Device for the Treatment of Broad Based Intracranial Aneurysms: A Single-Center Retrospective Observational Analysis.
Observational study in Clinical neuroradiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeIntracranial aneurysms are a major cause of hemorrhagic stroke, often requiring endovascular intervention. The Woven EndoBridge (WEB) device offers a minimally invasive solution for wide-neck bifurcation aneurysms and typically requires only single antiplatelet therapy, reducing bleeding risks associated with dual regimens. However, long-term clinical and angiographic data remain limited.
methodsThis single-center, retrospective study analyzed 247 patients treated with the WEB device between January 2013 and December 2021, with clinical and imaging follow-up through June 2024. Demographics, aneurysm characteristics, procedural outcomes, and retreatment rates were evaluated. A competing risk model was applied to identify factors associated with retreatment.
resultsThe cohort included 247 patients (mean age: 63 years; 70% female) with 266 broad-based intracranial aneurysms. The overall retreatment rate was 12.8%, most occurring within the first year. Subgroup analysis revealed no significant differences based on aspect ratio (< 1.6 vs. ≥ 1.6) or device diameter (< 0.9 mm vs. ≥ 0.9 mm). Patients treated after 2018 had significantly lower retreatment rates (HR: 0.31; 95% CI: 0.13-0.71; p = 0.006), likely reflecting greater operator experience and introduction of the WEB17 model.
conclusionThe WEB device demonstrates durable aneurysm occlusion with a low long-term retreatment rate. Improved outcomes after 2018 suggest an effect of the learning curve and device refinement. Early imaging follow-up and continued operator training remain essential to optimize procedural success.
