Many aspects of an animal or plant can be correctly called adaptations, though there are always some features whose function is in doubt. By using the term adaptation for the evolutionary process, and adaptive trait for the bodily part or function (the product), the two senses of the word may be distinguished.
Angioplasty (or Balloon angioplasty) is an endovascular procedure to widen narrowed or obstructed arteries or veins, typically to treat arterial atherosclerosis. An empty, collapsed balloon, known as a balloon catheter, is passed over a wire into the narrowed locations and then inflated to a fixed size.
You may have bleeding in your leg or arm where a catheter was inserted. Usually this simply results in a bruise, but sometimes serious bleeding occurs and may require a blood transfusion or surgical procedures. Other rare risks of angioplasty include: Heart attack. Though rare, you may have a heart attack during the procedure. Coronary artery damage.
