Article Synopsis
- The study aimed to identify the optimal sizes for middle cerebral artery (MCA) bifurcation aneurysms that are most suitable for treatment with the Woven EndoBridge (WEB) device, focusing on aneurysm width and neck dimensions.
- Using a large retrospective database, the researchers analyzed unruptured MCA bifurcation aneurysms and established ideal cutoff values of 6.1 mm for width and 4.6 mm for neck size regarding treatment effectiveness.
- Findings indicated that aneurysms smaller than these cutoff values had significantly higher rates of occlusion (93% for width and 90% for neck) and lower retreatment rates compared to larger aneurysms, highlighting the importance of
Article Synopsis
- - The study aimed to create a predictive calculator to determine the chances of achieving adequate occlusion (Raymond-Roy classification 1 or 2) when using the woven endobridge (WEB) device for intracranial aneurysms, drawing from a large dataset.
- - Analyzed data from 356 patients across 30 centers worldwide revealed that larger aneurysm neck size and partial thrombosis were linked to lower chances of successful occlusion, while the calculator showed good predictive accuracy.
- - The newly developed tool offers a valuable resource for clinicians to better estimate the success of using the WEB device in treating intracranial aneurysms, helping to enhance patient care.
Article Synopsis
- - The Woven EndoBridge (WEB) device is used for treating wide-neck intracranial bifurcation aneurysms smaller than 10 mm, but there's limited data on its effectiveness for larger aneurysms.
- - A study reviewed data from the WorldWide WEB Consortium involving 898 patients to compare outcomes between small and large aneurysms, using propensity score matching (PSM) for accuracy.
- - Results showed that large aneurysms had significantly lower rates of adequate occlusion and higher rates of retreatment compared to small aneurysms, suggesting that these findings could influence treatment choices and patient discussions in the future.
Article Synopsis
- The Woven EndoBridge (WEB) device is being studied as a new treatment for intracranial aneurysms, particularly its effectiveness for off-label uses which require further investigation.
- A study of 162 patients utilizing machine learning developed predictive models for successful occlusion after off-label WEB treatment, analyzing various factors linked to outcomes.
- Findings indicated that larger neck diameter and the presence of daughter sacs significantly predicted poorer occlusion results, emphasizing the need for further validation to refine patient selection and treatment strategies.
Background And Purpose: Despite the numerous studies evaluating the occlusion rates of aneurysms following WEB embolization, there are limited studies identifying predictors of occlusion. Our purpose was to identify predictors of aneurysm occlusion and the need for retreatment.
Materials And Methods: This is a review of a prospectively maintained database across 30 academic institutions.
Article Synopsis
- This study examined how taking antiplatelet medications before and after procedures affects the risk of thromboembolic complications (TECs) in patients treated with the Woven EndoBridge (WEB) device for specific brain aneurysms.
- It analyzed data from multiple centers, involving a total of 1412 patients, to determine if antiplatelet drugs reduce the likelihood of TECs, finding that those who took them before the procedure had a significantly lower risk.
- The study concluded that while preprocedural antiplatelet use significantly lowers the chances of TECs, the effect does not carry over when the medication is taken post-procedure.
Background: The Woven EndoBridge (WEB) devices have been used for treating wide neck bifurcation aneurysms (WNBAs) with several generational enhancements to improve clinical outcomes. The original device dual-layer (WEB DL) was replaced by a single-layer (WEB SL) device in 2013. This study aimed to compare the effectiveness and safety of these devices in managing intracranial aneurysms.

Objective: The Woven EndoBridge (WEB) device is an intrasaccular flow disruptor designed for wide-necked bifurcation aneurysms. These aneurysms may require the use of a concomitant stent. The objective of this study was to determine the clinical and radiological outcomes of patients undergoing stent-assisted WEB treatment.

Initial studies have demonstrated that approximately 90% of patients have same or improved long-term aneurysm occlusion after the initial 6-month follow up. The aim of this study is to assess the long-term follow-up in aneurysms that have achieved complete occlusion at 6 months.

Article Synopsis
- The Woven EndoBridge (WEB) device is FDA-approved for treating wide-necked bifurcation aneurysms, but its effectiveness across different locations has only been studied in limited case series.
- A research study analyzed data from 572 aneurysms treated with the WEB device at 22 academic institutions, focusing on various bifurcation types, including AComA, ACA, basilar tip, ICA, and MCA aneurysms.
- Results showed that basilar tip (91.6%) and ICA bifurcation (96.7%) aneurysms had significantly higher occlusion rates compared to ACA (71.4%) and AComA (80.6%) aneurysms, making this the largest study to assess
