<h3>Introduction</h3> WEB (Woven Endobridge, Sequent Medical, Aliso Viejo, California, USA) device represents a new generation of the called ¨endosaccular flow disruption¨ devices which have been designed for the treatment of wide-neck bifurcation aneurysms (WNBA). early clinical experiences have reported a good safety and effectiveness profile. Current limitations during the endovascular treatment of those WNBA using conventional approaches such as high recanalization rates, significant thromboembolic complications and need for re-treatments may be overcome using this braided technology. <h3>Matherials and Methods</h3> High-frequency optical coherence tomography (HF-OCT) consists of an endovascular catheter-based imaging technique that has been validated in either peripheral and interventional cardiology fields. oct technology combines the use of infrared light and tridimensional reconstruction, allowing the evaluation (micron-scale level) of the inner wall of the vessel, intravascular devices implanted as well as associated hemodynamic and biological responses. <h3>Discussion</h3> We report here, the intracranial use of OCT to evaluate the et of a carefully selected patient with a WNBA located in posterior circulation treated with WEB technology. We describe for the first time in humans these technical and angiographic aspects intra-procedural as well as the visualization close to the histology of the findings immediately after WEB deployment. <h3>Reference</h3> Vardar Z, <i>et al</i>.
