Can a stent get clogged?

A stent can get clogged. A complication of a stent is that it can get restenosed by gradual renarrowing of the stented segment. This is typically seen 3 to 12 months after stent placement. It is seen in 15 percent of people with a bare metal stent and less than 10 percent of people with a drug-eluting stent. It can present as recurrent chest pain or even a heart attack in a small population of people. These symptoms are often managed by repeat stenting.
