Purpose: To present the application of a covered stent for the management of a left internal carotid artery (ICA) aneurysm that had recanalized following embolization with Onyx.Case Report: A 54-year-old man had a giant intracavernous aneurysm of the left ICA successfully occluded with Onyx. Recurrence of symptoms 5 months later prompted control angiography, which showed partial recanalization of the aneurysm. The aneurysm neck was successfully sealed by placing 2 polytetrafluoroethylene-covered stents across it. Control angiography performed at 12 months after stent placement showed no stenosis or signs of recanalization of the aneurysm.Conclusions: Recanalization of giant intracavernous carotid aneurysms post-Onyx treatment may be safely treated with placement of covered stents across the aneurysm neck.
