FIG 2. Lateral views of the left carotid artery bifurcation.
A, Approximately 70% short-segment, circumferential, atherosclerotic stenosis of the internal carotid artery origin (arrow).
B, Appearances after deployment of a SMART stent, which crosses the origin of the external carotid artery. Note stenosis of the external carotid artery origin as a consequence of stenting across the carotid bifurcation. This is usually of no clinical significance.
FIG 3. Lateral views of the right carotid artery bifurcation.
A, Severe (approximately 90%), long-segment, atherosclerotic stenosis of the common and internal carotid arteries. There is minimal opacification of the external carotid artery (arrow).
B, Appearances after deployment of a SMART stent within the common carotid artery.
