(a long, tube-shaped device) into a major blood vessel, usually the one at the top of your thigh. They then steer the catheter through your blood vessels to the areas where your arteries are narrow enough to cause claudication. Once they’re at the narrowed area, they can then inflate a balloon to widen the artery. They can also place a stent, a scaffold-like structure that will hold the artery open so blood can flow through easily. Bypass surgery. This procedure takes a blood vessel from elsewhere in your body and uses it to craft a detour-like route for blood to travel. Once in place, that bypass provides enough blood flow to prevent intermittent claudication. Atherectomy. This procedure uses a catheter device to remove plaque buildup on the inside of narrowed arteries.
