(a) Computerized tomography angiogram (CTA) reveals a large left carotid artery aneurysm with ulcerated intramural thrombosis (arrows), and (b) CTA with 3D reconstruction shows the aneurysm with irregular thrombus involving the left distal common and proximal internal carotid arteries.

Computerized tomography angiogram (CTA) showed a large amount of thrombus inside the aneurysm sac (Figure 1).
(a) Intraoperative angiogram confirms the left carotid aneurysm, and (b) coil embolization of the left external carotid artery (arrow) is performed using Interlock coils (Boston Scientific Corp., Marlborough, MA) to prevent type II endoleak.

Gore & Associates Inc., Flagstaff, AZ) and coil embolization of the left ECA were performed (Figure 2).
(a) Postoperative computerized tomography angiogram (CTA) shows that the Viabahn (W. L. Gore & Associates Inc., Newark, DE) covered stent is widely patent, with complete thrombosis of the aneurysmal sac, and (b) CTA with 3D reconstruction demonstrates that the flexible covered stent is smoothly following the natural course of the carotid artery without kink or stenosis.
