WebFeb 25, 2024 · Flow diverter stents are revolutionizing the treatment of large wide-neck and fusiform intracranial aneurysms. But those devices are less effective when such aneurysms are located at arterial bifurcations, since two vessel branches are involved and flow can only be diverted in one at a time. WebFlow diverters are thought to work primarily through 2 mechanisms: (1) the fine-mesh diversion device leads to a reduction of flow inside the aneurysm, and (2) it provides a scaffold for endothelialization across the aneurysm neck, permanently excluding it …
