An angioplasty is a procedure that uses x-ray guidance and a balloon catheter to open a blocked or narrowed blood vessel. By opening a blocked or narrowed blood vessel, blood flow will improve. A catheter will be inserted that will have a balloon over it which is inflated to open the blockage. Occasionally, these balloons will be coated with a chemotherapy agent, or drug-eluding balloons. Sometimes a stent may need to be placed if there is recoil of the blood vessel after the angioplasty.
