Which vascular procedure did the patient undergo on the left leg?

• A. Right common iliac artery stent
• B. Gallbladder surgery
• C. Left femoral-to-popliteal bypass graft
• D. Carotid endarterectomy

Answer: (C)

The scenario describes a bypass procedure in the lower extremity. A left femoral-to-popliteal bypass graft connects the femoral artery to the popliteal artery to bypass a blocked segment in the femoropopliteal region, restoring blood flow to the leg. The other options don’t fit because they involve different areas or procedures: a stent in the right common iliac artery would be on the right side and in the pelvic/iliac region, gallbladder surgery is biliary, and a carotid endarterectomy treats disease in the neck's carotid artery. Therefore, the vascular procedure performed on the left leg is the left femoral-to-popliteal bypass graft.
