Which procedure involves surgical removal of plaque buildup from the interior of an artery?

• A. Nebulizer
• B. Atheroma
• C. Atherectomy
• D. Sinusitis

Answer: (C)

The main idea is a procedure that physically removes plaque from inside an artery to open up the vessel. This is called atherectomy. It’s used to treat atherosclerotic arteries where buildup narrows blood flow, and the goal is to cut away or shave off the plaque so blood can circulate more freely. Nebulizers deliver medications to the lungs, not remove arterial plaque. Atheroma is the plaque itself, not the procedure. Sinusitis is inflammation of the sinuses, unrelated to arteries. So the procedure that fits the description is atherectomy.
