Does a collapsed stent need fixing?
Q. About 10 years ago, after being unexpectedly short of breath a few times, my brother had a stent put in during an angioplasty procedure. He has been fine since. During a routine visit to his cardiologist, he was told he had a blockage in the vicinity of the stent. A CT scan showed that the stent had collapsed but blood was passing through arteries around the stent. Both my brother's doctor and a cardiologist he saw for a second opinion said the stent cannot be replaced and, since my brother isn't having any symptoms, told him not to worry about it. This doesn't sound right to me. Shouldn't a stent be replaced if it is defective?
A. Although most stents work like they're supposed to, the technology isn't foolproof. Occasionally, a stent doesn't open completely during implantation, making it more likely that problems will develop later. A more common problem is blockage of the stent caused by the body's healing response. The blockage can be partial or total.
