The Woven EndoBridge for Wide-Neck Bifurcation Aneurysms: A Retrospective Study of 120 Cases with Expanded Indications Covering All Subtypes.
Article in Neurointervention, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe Woven EndoBridge (WEB) was introduced in Japan in January 2021 and approved for all subtypes of wide-neck bifurcation aneurysms (WNBA). This retrospective study evaluated the safety and efficacy of the WEB device for all subtypes of WNBA. MATERIALS AND
methodsAll patients treated with the WEB at our facility between January 2021 and May 2024 was reviewed. We selected the WEB device according to an oversizing policy, based on cumulative clinical evidence from global experience.
resultsWe analyzed 120 aneurysms in 117 patients (56 males and 61 females with a mean age of 65.5±12.7 years). There were 45 anterior communicating artery aneurysms, 27 middle cerebral artery aneurysms, 17 internal carotid artery-posterior communicating artery aneurysms, 15 basilar artery top aneurysms, and 16 aneurysms in other locations. Aneurysm characteristics included a maximum diameter of 6.5 [5.3, 7.7] mm, height of 4.9 [3.9, 6.0] mm, width of 4.8 [4.0, 6.2] mm, and dome/neck ratio of 1.2 [1.1, 1.4]. All data are expressed in median [interquartile range]. Angiographic follow-up at 12 months in 96 cases showed complete obliteration in 68.8% and adequate obliteration in 90.6% of cases. Intraoperative ischemic events occurred in 5 cases (4.2%). Hemorrhagic events occurred in 2 cases (1.7%), with symptoms resolving by discharge, except for 1 case of mild paralysis. During follow-up, 1 patient developed a major stroke, resulting in morbidity (0.8%). Retreatment was required in 3 cases (2.5%). On multivariate analysis for complete occlusion at 12 months following WEB treatment, age was statistically associated with the outcome (odds ratio, 0.957 per year; 95% confidence interval, 0.919-0.996; P=0.033).
conclusionWEB is safe and effective for all subtypes of WNBA, with a low retreatment rate using an oversizing policy. This is the first report in a Japanese population.
