title: Covered stents to treat partial recanalization of onyx-occluded giant intracavernous carotid aneurysm.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
