Angioplasty: With respect to how science is applied to address the issue of this disease, when the symptoms of PAD persist, patients undergo a procedure known as Angioplasty. It is done to open obstructed or restricted arteries. To flatten the plaque, the doctor may blow up a tiny balloon inside the artery. To aid in the artery's healing, the balloon may occasionally be coated with medication. To lessen the possibility that the artery would re-narrow, your doctor might also place a tiny mesh tube known as a stent. When angioplasty is less likely to be effective, bypass surgery may be done to manage extreme pain, repair wounds, or salvage a damaged foot or leg. In this treatment, your surgeon reroutes a blocked artery in your leg using a segment of another blood vessel from your body or an artificial vessel.
