Percutaneous Transluminal Angioplasty is similar to angioplasty of the arteries of the heart, except this is for the disease of the legs and it helps improve leg circulation. This is accomplished by inflating a balloon at the area of fatty deposits. Sometimes an atherectomy is performed, which is the scraping and removal of those fatty deposits in the arteries of the legs. After this procedure, a patient will be able to walk for longer distances without feeling pain in the legs.
