Which term means removal of the fatty plaque?

• A. Arthrography
• B. Atherectomy
• C. Atherosclerosis
• D. Atrioventricular

Answer: (B)

Removing fatty plaque from an artery is called atherectomy. The root 'athero-' refers to fatty plaque, especially within arteries, and '-ectomy' means surgical removal. This describes a procedure that physically shaves off or extracts the plaque from the vessel, often using a catheter-based device. In contrast, arthrography is imaging of a joint, atherosclerosis is the disease process of plaque buildup in arteries, and atrioventricular relates to the relationship between the atrium and ventricle of the heart. So the term that means removal of the fatty plaque is atherectomy.
