Where is the balloon dilator inserted during coronary artery angioplasty?

• A. Carotid artery
• B. Subclavian artery
• C. Radial artery
• D. Femoral artery

Answer: (D)

During coronary artery angioplasty, the balloon dilator is typically inserted through the femoral artery. This approach is commonly used because the femoral artery provides direct access to the arterial system, allowing for the introduction of catheters and balloon devices necessary for the procedure. The femoral artery is a major blood vessel in the thigh and provides a large and stable entry point for interventions involving the coronary arteries. Once the balloon dilator is advanced through the femoral artery, it travels up through the aorta and into the coronary arteries, where it can be inflated to open up narrowed or blocked areas. While other arteries such as the radial or subclavian arteries can also be used for catheterization in some scenarios, they are not the most common access points for coronary angioplasty. Each access site has its own advantages and considerations based on the patient's condition, but the femoral artery remains one of the most widely used and taught sites for this procedure.
