What is the surgical procedure or operation for inserting a stent, a mold to keep a passageway open, into an anatomical vessel?

• A. Stenting
• B. Antibody
• C. Bacteria
• D. Metabolic Syndrome

Answer: (A)

Stenting is the surgical procedure for inserting a stent into a blood vessel to keep it open. In this operation, a catheter is guided to the narrowed artery and a stent—a small mesh tube—is placed and often expanded with a balloon so it supports the vessel wall and prevents re-narrowing. This is commonly done during angioplasty to treat blockages from atherosclerosis. The other terms are not procedures: an antibody is an immune protein, bacteria are microorganisms, and metabolic syndrome is a cluster of metabolic risk factors.
