| Abstract: | The presence of branching vessels, a wide aneurysm neck, and/or fusiform morphology represents a challenge to conventional endovascular treatment of visceral artery aneurysms. A variety of techniques and devices have emerged for the treatment of intracranial aneurysms, in which more aggressive treatment algorithms aimed at smaller and morphologically diverse aneurysms have driven innovation. Here, modified neurointerventional techniques including the use of compliant balloons, scaffold- or stent-assisted coil embolization, and flow diversion are described in the treatment of visceral aneurysms. Neurointerventional devices and their mechanisms of action are described in the context of their application in the peripheral arterial system. |
