Which surgical option is used for treating arterial insufficiency?

• A. Apheresis
• B. Cryotherapy
• C. Endovascular graft or bypass
• D. Amputation

Answer: (C)

Restoring adequate blood flow to an ischemic limb is the goal when arteries are narrowed or blocked. The surgical approach that directly achieves this is revascularization, which can be done by bypassing the diseased segment or by endovascular means that place a graft or stent to reestablish a clear pathway for blood to reach downstream tissues. An endovascular graft or bypass reopens perfusion, helping wounds heal and reducing the risk of limb loss. In contrast, apheresis is a blood-cleansing procedure, cryotherapy is used for tissue or pain management rather than restoring circulation, and amputation is a last-resort option when the limb is nonviable and does not address the underlying blood flow. Revascularization thus best treats arterial insufficiency by directly reestablishing arterial perfusion.
