Safety and EffecTiveness of the Silk Vista Flow DiverteR in the TrEatment of Unruptured IntracrAnial AneurysMs

Flow diverter stents (FDS) are braided stents with specific porosity that promotes the flow redirection within the parent vessel and outside the aneurysm sac, and the endothelialization. The FDS placed in the parent artery and covering the aneurysm sac will promote the intra-aneurysmal blood stagnation and parent vessel wall healing. All of these promoting, the aneurysm's thrombosis and ist regression
