Flow diversion has become increasingly used as the primary treatment for unruptured aneurysms (upper left); however, its applications are being pushed to new clinical and anatomic frontiers. Shown are several cases highlighting the treatment of intracranial aneurysms with flow diversion, including a giant right middle cerebral artery aneurysm (upper right), a ruptured fusiform right anterior inferior cerebellar artery aneurysm (lower left), and a vertebrobasilar mycotic aneurysm (lower right). See the article by Carnevale et al. (V2).
