After a restricted placement, patients typically receive indefinite aspirin therapy.
A stent can be defined as any medical device that supports tissue, but more commonly, the term refers to a specific medical device that is placed in an artery. An arterial stent is a mesh-shaped tube, usually made of metal, that can expand once it is inserted into an artery. Its most frequent placement is in the coronary arteries, which are normally blocked by plaques that form inside them.
A stent is a support device inserted into the body.
During an angioplasty, a stent can be inserted into an artery and is usually inflated with a balloon catheter. The procedure starts from the femoral artery in the groin or the axillary artery in the armpit, and the stent is guided into the appropriate artery. The stent acts as a kind of scaffold for the artery during any repair or surgical procedure. It is usually left in the artery permanently. The stent supports the narrowed or blocked artery, keeping it open so blood can flow more freely.
Stent implantation can be performed by a cardiologist.
The risks associated with stent placement are minimal compared to the risk of untreated blocked arteries and include clotting, additional damage to an artery during the procedure, and an allergic reaction to the material. All patients are placed on a blood thinner, or blood thinner, after the procedure and then, normally, aspirin therapy is needed indefinitely.
During an angioplasty, a stent can be inserted into an artery and is usually inflated with a balloon catheter.
There is a possibility that an artery with a stent in place will collapse or become blocked again. This is known as restenosis. There are some stents, called drug-eluting stents, that are coated with drugs that release into the artery and help prevent it from closing again. There are no known problems associated with the long-term presence of stents other than the possibility of restenosis. Patients who have had stents implanted will be closely monitored by their cardiologist, or other specialist, for a few weeks after the procedure and then at routine intervals for examinations. Magnetic resonance imaging (MRI) is not recommended for at least four weeks after the procedure, unless under the direct supervision of a cardiologist.
