how long do stents stay open
The Lifetime of a Stent. In a majority of the cases, stents stay open forever. In situations during which a patient does experience a problem, it is mostly due to the development of new blockages, not because of the stent. In less than 10% of the cases, a stent can get re-blocked, resulting in a condition called in-stent restenosis. This may require your doctor to reopen the blocked stent with a balloon or place a new stent inside the blocked stent.
