No. Carotid stent placement does not clean out existing plaque. It pushes it against the vessel wall trapping it with the stent.
No. Revascularization uses the pressure of the balloon (angioplasty) or stent to open the artery to allow unimpeded or improved blood flow. The plaque is not removed during the procedure. Aggressive medical treatment and lifestyle changes can reduce the risk of restenosis and slow plaque growth in some cases.
No. Stent pushes plaque out of the way.
