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.
