<h3>Materials and Methods</h3> Consecutive patients treated with WEB were selected from March 2016 to February 2020 in six different centers in our country. We retrospectively evaluated clinical records, anatomical and angiographic variables. <h3>Results</h3> 73 patients (mean age: 52.8) with 75 IA were treated with WEB. History of SAH in 18/75(24%). A total of 84 devices were attempted and finally implanted 75 (1.1 device per aneurysm) of these, eight devices were exchanged due to sizing failures, one case of WEB miss-opening was discarded. 59/75 (78.6%) were located in anterior circulation (MCA: 32, ACA: 19, ICA: 8). Sixteen cases in the posterior circulation (Basilar tip: 13, SCA: 2, VBJ: 1). An additional strategy was observed in five cases (6.6%): high porosity stent in four and balloon-assisted web in one case. WEB SL was used in 82.6% and WEB SLS configuration in 13/75. Radiological follow-up available 6–12 months in 49/73 (67%) with complete occlusion in 54.9% and adequate occlusion rate according to WOS in 93%. None thromboembolic complications were reported. Two patients with severe hemorrhages procedure-related (one case of ICA rupture secondary to DAC advancement, and one tip-basilar aneurysm perforated with the microwire). Overall morbid-mortality of 2.6%. <h3>Conclusion</h3> In this multicenter experience, the treatment of IA using WEB was feasible, safe, and effective. Overall morbid-mortality (2.6%) aligned with previous publications. <h3>Reference</h3> Kabbasch C, <i>et al</i>.
