Flow diverters constitute a new generation of flexible self-expanding, stent-like devices with a high-metal surface-area coverage for the endovascular management of wide-necked, fusiform, large, and giant unruptured intracranial aneurysms. They achieve aneurysm occlusion through endoluminal reconstruction of the dysplastic segment of the parent artery that gives rise to the aneurysm. To our knowledge, there is no report on the use of flow diverters for the management of occlusive cerebrovascular disease. We describe the novel use of telescoped flow diverters in a construct that acts as an endovascular bypass for the management of symptomatic chronic carotid occlusion. In long carotid occlusions with a burden of extensive clots and atherosclerotic plaque, we found that the reduced porosity of the diverter mesh serves as an effective barrier to in-stent clot protrusion and distal embolization. Diverter implantation allows subsequent angioplasty. With this patient report, we propose a new potential application for flow diverters in the management of occlusive cerebrovascular disease. The optimal application of these devices will continue to be defined as clinical experience evolves.
