Which statement best describes the stenting procedure in vascular intervention?

• A. Endarterectomy
• B. Angioplasty
• C. Stenting
• D. Bypass

Answer: (C)

Stenting is the placement of a small mesh scaffold inside a narrowed artery to keep it open. It’s usually done after balloon angioplasty widens the lesion, with the stent acting as a scaffold to prevent elastic recoil and restenosis so the lumen stays patent longer. This is an endovascular approach, done via a catheter, and it differs from endarterectomy, which surgically removes plaque, and from bypass, which creates a new route around the blockage. Angioplasty alone uses balloon dilation to widen the vessel but does not provide a lasting scaffold unless a stent is placed; in practice, stenting is often performed in conjunction with angioplasty.
