Coronary Stent Placement

It is not uncommon for arteries to re-clog after an angioplasty is performed.  Sometimes scar tissue may form at the angioplasty site or additional plaque may re-close the artery.

In about 80 percent of all angioplasties, surgeons prop open the artery with a coronary stent, which is a mesh cylinder that keeps scar tissue and plaque from re-forming.  The stent forms itself to the wall of the artery and keeps it open so blood can flow through the artery.

Although the coronary stent is a viable option for sufferers of repeat artery closures, the stent is not 100 percent effective and closure still occurs in about 150,000 patients annually.  This re-closure in an artery with a coronary stent is called in-stent restenosis.

At Norton Heart Care there are new treatment options available for patients with in-stent restenosisthat  help cardiologist treat re-clogging arteries without open-heart surgery.

What to expect during this procedure

  • During angioplasty, a small, expandable wire mesh-like stent is permanently inserted into the artery.
  • The balloon is placed inside the stent and inflated.
  • The stent is then opened and pushed into place against the artery wall to keep the narrowed artery open.
  • Because the stent is a mesh-like cylinder, the cells lining the blood vessel are able to grow through and around the stent, helping to secure it.

What to expect after this procedure

  • You will be moved to an area where your heart rate, pulse and blood pressure will be closely monitored.
  • The catheter insertion site will be checked for bleeding, and you will be given medication for discomfort.
  • Pain is minimal and recovery is rapid. You usually can start walking within 4 to 8 hours after angioplasty.
  • The average hospital stay for most procedures is one to two days.
  • It is not uncommon for arteries to re-clog after angioplasty because of scar tissue or a recurrence of plaque buildup. If you do experience another blockage, a surgeon typically performs another angioplasty or a different procedure to clear the artery.
