Angioplasty or Ballon Angioplasty
The usefulness of angioplasty depends upon the severity of arterial narrowing. Angioplasty is often recommended when arterial narrowing is moderate to severe, or when only one or two coronary arteries are severely narrowed.
The doctor threads a thin tube through a blood vessel in the arm or groin up to the involved site in the artery. The tube has a tiny balloon on the end. When the tube is in place, the doctor inflates the balloon to push the plaque outward against the wall of the artery. This widens the artery and restores blood flow.
