A 37-year-old man and a 23-year-old man with cervical carotid artery aneurysms were treated with covered stents. The covered stent was constructed from a Palmaz stent covered with an expanded polytetrafluoroethylene graft. Angiography showed the aneurysms had disappeared immediately after the procedure. Patency of the covered stents was confirmed at 18 and 34 months after intervention by three-dimensional computed tomography angiography. The covered stent allows relatively noninvasive reconstruction of the parent artery that immediately brings about complete thrombosis of the aneurysm. However, delivering the covered stent to the carotid artery may be difficult.
