Optimal woven endobridge (WEB) device-aneurysm volume: using automated volumetric software to predict aneurysmal occlusion status after WEB treatment.
Article in Acta neurochirurgica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundOptimal Woven EndoBridge (WEB) sizing is crucial for successful implantation. We used three-dimensional (3D) software, Siemens Aneurysm Analysis v. VD30B, to determine the potential of WEB device-aneurysm volume (DAV) ratios in predicting post-treatment occlusion status.
methodsWe retrospectively reviewed 35 unruptured intracranial wide-neck bifurcation aneurysms treated using the WEB. The study evaluated the association between the DAV ratio and aneurysm obliteration during follow-up. The primary aim of the study was to determine the optimal DAV ratio for predicting occlusion status following WEB treatment.
resultsThe success rate of treating all unruptured aneurysms with the WEB was 100%. The median duration to final follow-up was 365 ± 184.0 days with all 35 patients having a mean modified Rankin Scale score of 0. One (2.9%) patient experienced a transient ischemic attack with hemiparesis perioperatively. A follow-up angiography revealed complete occlusion (WEB Occlusion Scale [WOS] A and B) in 25 (71.4%) of 35 patients and WOS C and D in 10 (28.6%) of 35. The median DAV ratio significantly differed between the groups. The median DAV ratios were 0.97 in the complete occlusion group and 0.84 in the WOS C and D group, respectively (p = 0.002). A receiver operating characteristic curve produced an area under the curve of 0.76 (confidence interval: 0.56-0.96). The optimal DAV ratio cut-off and the highest Youden index for complete occlusion was 0.90.
conclusionCalculating DAV ratios using 3D software may help improve the rate of complete occlusion following WEB treatment.
