Rupture of a Previously Unruptured Cerebral Aneurysm 6 Years After Treatment With the Woven EndoBridge (WEB) Device: Case Report

Background Introduced to the clinical field in 2011, the Woven EndoBridge (Sequent Medical) device is recognized as a significant innovation for managing wide‐neck bifurcation aneurysms. Delayed aneurysm ruptures, typically occurring hours to months after Woven EndoBridge placement, have been reported. Methods We present a case of a previously unruptured, known residual aneurysm that ruptured 6 years after treatment with a Woven EndoBridge device. This case underscores the fact that intrasaccular flow diversion, without achieving aneurysm occlusion, does not prevent aneurysm rupture. Conclusion Consequently, aneurysm retreatment to attain complete occlusion is imperative.
