FIG 3. Follow-up angiograms obtained after stent placement.

A, High-grade stenosis at the origin of the ICA is seen.

B, Implantation of a Wallstent completely restored the vascular lumen. Note the slight narrowing at the origin of the ECA and minimal fusiform dilatation above the distal end of the stent at the site of the protective balloon.

C, After 6 mo, the stent is covered by a smooth layer of neointima, which is prominent within the distal CCA. At the flow divider at the bifurcation, a bulblike bulging is seen. The ECA remained patent. Dilatation at the former site of the protective balloon is no longer visible.
