The Woven EndoBridge (WEB) for recurrent aneurysms: Clinical and imaging results

IntroductionThe Woven EndoBridge (WEB) device is a novel intrasaccular flow disrupter designed for wide-necked aneurysms. We present our results of WEB treatment in previously treated and reopened aneurysms.Materials and methodsBetween February 2015 and December 2017, 17 patients with reopening of previously treated aneurysms were treated using the WEB device. Initial treatment was clipping in one, WEB in five and coiling in 11 aneurysms. Six aneurysms had two or three previous treatments. Mechanism of aneurysm reopening was clip remnant in one, compaction without regrowth in three, focal regrowth in five, reopening in partially thrombosed aneurysms in three and WEB compression in five aneurysms.ResultsEndovascular treatment of the recurrent aneurysm was possible in all 17 patients with good WEB position obtained. Additional devices were used in three of 17 patients (18%): coils in two and stent in one patient. No technical, hemorrhagic or thromboembolic complications occurred (0%, 97.5% confidence interv...
