Stents are metal spirals or tubes that are placed in a coronary artery stenosis to improve accessibility.
Stents come into direct contact with blood in the first weeks after placement. Therefore, clots can sometimes form on the inside of the stent which can re-seal the coronary artery. To reduce this risk, you should take several blood thinners in the first weeks after a stent placement.
