    TAKE HOME MESSAGE

    • WEB can be an option for aneurysms ≥ 10mm.
    • VIA 33 has a specifically engineered reinforced distal portion that allows the device`s recapture and redeployment but can make catheterization harder.
    • Sometimes, navigation could be the most complex step of the procedure.
    • Two 0,014” guidewires can be an alternative when using a 0,033” ID microcatheter.
