A stent is a tiny stainless-steel mesh tube that acts as a kind of scaffolding to hold open an artery that has become blocked. Stenting increases the likelihood that your artery remains dilated or unblocked after a percutaneous coronary intervention (PCI) procedure.
A fine, flexible, hollow tube (catheter) with a small inflatable balloon at its tip is passed into an artery in either your groin or arm and directed to your heart using X-ray screening. Once it reaches the narrowed or blocked section, the balloon is inflated to briefly open up the artery and restore blood flow. The stent is then inserted. Once the balloon is deflated and removed, the stent remains in the artery.
All patients will require anti-thrombotics after the procedure to prevent any blood clotting.
