Flow disruption with the Woven EndoBridge WEB device is an innovative technique for the endovascular treatment of wide-neck bifurcation aneurysms. Patients with wide-neck bifurcation aneurysms for which WEB treatment was possible were included. Clinical data including adverse events and clinical status at 1 month and 1 year were collected and analyzed. A core laboratory evaluated anatomic results at 1 year following the procedure.
Ten European neurointerventional centers included 55 patients 38 women; 27—77 years of age; mean, Aneurysm locations were the middle cerebral artery in 25 aneurysms Procedural morbidity and mortality at 1 month were, respectively, 1. Morbidity and mortality at 1 year were, respectively, 3. Endovascular treatment is now the first-line treatment for ruptured aneurysms.
However, at least in Europe, the tendency is to give priority to endovascular treatment. Thus, more complex endovascular techniques have been developed, such as balloon-assisted coiling, stent-assisted coiling, and flow diversion. Flow disruption is now a well-established procedure for the treatment of wide-neck bifurcation aneurysms. Introduced in in Europe, the Woven EndoBridge WEB; Sequent Medical, Aliso Viejo, California is the only intrasaccular device that has been extensively evaluated in the literature with several single- and multicenter, retrospective, and prospective series.
Written informed consent was obtained for all patients. The indication for endovascular treatment was determined in each center by a local multidisciplinary team that included neurosurgeons and neuroradiologists.
The selection of aneurysms treated with the WEB device was performed autonomously in each center by the interventional neuroradiologists according to aneurysm characteristics aneurysm status, aneurysm location and size, and neck size. The treatment of aneurysms with the WEB was performed by using techniques similar to those used in the treatment of aneurysms with coils. The study protocol did not specify the antiplatelet regimen to be followed, and it was managed in each center as indicated for typical endovascular treatment with coils or stents and coils.
