If a bare metal stent re-narrows, what are my treatment options?

Currently, about 25 percent of patients who receive bare metal stents and 10 percent of patients who receive drug-eluting stents develop re-narrowing inside the stent within 6 to 12 months after receiving it. A bare metal stent is a small, metal mesh tube that is inserted into an artery to prop the artery open and allow blood to flow through. Blocked arteries are serious and can cause heart attack, stroke and kidney failure, among other health problems. Drug-eluting stents are metal stents that release small amounts of a medication designed to help prevent the artery from re-narrowing.
Traditionally, patients who experience re-narrowing after stent placement are treated with the placement of a second drug-eluting stent to reopen the artery.
Another promising option may be treatment with an angioplasty balloon coated with a medication that is released into the blood vessel’s inner wall. This new device appears to treat a reblocked stent as well as avoid the placement of a second stent.
These are early results and will need more research. The study that yielded promising results is named Paclitaxel-Eluting PTCA-Balloon Catheter in Coronary Artery Disease II-In-Stent Restenosis (PEPCAD II-ISR).
