The right common carotid artery was patent but showed 80% long-segment stenosis in its proximal segment (Figs. 1 and 2).
Aortic arch angiogram demonstrating the single patent severely stenosed carotid artery. The arrows point to the stenosed right brachiocephalic artery (White arrow), occluded left carotid (Black arrow) and occluded left subclavian arteries (interrupted arrow).

Angiogram following stenting of the stenosed carotid artery segment using a self-expanding Precise 8 x 40 mm Nitinol stent (J&J) which was post-dilated using a 6 mm balloon. The arrows point to the proximal and distal ends of the stent in the carotid artery.

The left subclavian artery was occluded at its ostium, and the sole patent branch of the aortic arch was the left common carotid artery, which showed a proximal 90% stenosis <10 mm in length (Fig. 4).

Angiogram following balloon angioplasty of the severely stenosed carotid artery using 2.5 x 15 mm and 3.5 x 15 mm balloon catheters.
