What is it?
A stent is a small device, similar to an expandable mesh tube, that is implanted inside an artery treated by angioplasty to help keep it open.
What is it used for?
It is used together with coronary angioplasty to reduce the risk of the artery narrowing again after treatment. The decision to place one or more stents depends on the characteristics of each case, assessed by the medical team during the procedure.
How is it performed, in general terms?
During angioplasty, once the blocked area has been widened with a balloon, the stent is positioned at the treated site and expanded so it adheres to the artery wall, where it remains permanently.
Typical preparation
Preparation is the same as for a coronary angioplasty. It is especially important to inform the medical team of any allergies to antiplatelet or anticoagulant medication. You can review the general guidelines for preparing for a study, which always work alongside your physician's specific instructions.
What happens afterward?
Antiplatelet medication is usually indicated for a period determined by the medical team, and should not be stopped without medical guidance, since it helps prevent clot formation in the stent. Recommendations about rest and follow-up checks are also provided.
Frequently asked questions
