Final answer:
Aorto-femoral bypass surgeries can be performed using an open surgical method or an endovascular approach to reroute blood flow from the aorta to the femoral artery in the lower body.
Step-by-step explanation:
Aorto-femoral bypass surgeries are performed through an open surgical method or an endovascular approach. This type of surgery is conducted to bypass diseased large blood vessels in the abdomen and groin areas. The goal is to reroute blood flow from the aorta to the femoral artery. The femoral artery is a major blood vessel that continues from the external iliac artery after it passes through the body cavity, and it supplies blood to the lower body. It divides into several branches, including the lateral deep femoral artery and the genicular artery, and eventually becomes the popliteal artery as it passes behind the knee.
