Computed tomography angiography shows a right extracranial carotid artery aneurysm (ECAA), with a 3.0 cm diameter, 5 cm long true aneurysm, and a left ECAA with a 2.1 cm diameter, 4.5 cm long true aneurysm (A) (arrows). Post-operative computed tomography angiography shows a patent graft one month after the second operation without aneurysmal dilatation (B).

Post-operative computed tomography angiography revealed patent grafts 1 year after the second operation (Fig. 1B).
Operative image shows a true aneurysm with intramural thrombus after application of an intraluminal shunt (A), reconstruction of the right internal carotid artery (ICA) with autologous great saphenous vein after resection of the right extracranial carotid artery aneurysm (B) and reconstruction of the left ICA with autologous great saphenous vein (C). Pathological examination of the surgical specimen revealed atherosclerotic change with no vasculitis or fibromuscular dysplasia (D).

After opening the internal carotid aneurysm, a carotid shunt was inserted between the common carotid artery and the distal internal carotid artery (ICA) (Fig. 2A). After removal of the carotid aneurysm sac, a bypass with an interposition graft was created with autologous saphenous vein (Fig. 2B). Pathological examination of the aneurysm sac revealed atherosclerotic change without any evidence of vasculitis or fibromuscular dysplasia (Fig. 2D).
