Flow Diverters for Unruptured Internal Carotid Artery Aneurysms: Dangerous and Not Yet an Alternative for Conventional Endovascular Techniques

摘要

With interest, we read the article of Lanzino et al1 about the use of flow diverters for proximal internal carotid artery aneurysms in 21 patients. There was a higher rate of complete occlusion at follow-up with flow diverters than in a matched series of aneurysms treated with conventional techniques (coiling, stent placement, ICA occlusion). Most important, there were no complications leading to permanent neurologic deficits or death, though 1 patient was found to have a complete ICA occlusion at 6 months without symptoms. The message in the article is that although longer follow-up is needed, flow diverters are probably better than conventional techniques for these ICA aneurysms because of a higher complete occlusion rate at follow-up.
