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

Abstract

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. 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. Consequently, aneurysm retreatment to attain complete occlusion is imperative.
