What is the stent?

stent can be defined as any medical device that supports tissue, but most often this term concerns a specific medical facility located in the artery. The arterial stent is a tube similar to a net, often made of metal, which can expand as soon as it is inserted into the artery. Its most common location is in coronary arteries, which are usually blocked by plaque created inside.

During angioplasty, the stent can be inserted into the artery and usually inflates with a Baloon catheter. The procedure starts either on the femoral artery in the weakness or axillary artery in the armpit, and the stent is leading to the correct artery. The stent acts as a type of scaffolding for artery during any surgical repair or procedure. It is usually left in an artery permanently. The stent supports a narrowed or blocked artery and keeps it open for free -flowing blood.

The risks associated with the location of the stent are minimal compared to the risk of untreated blocked arteries and includes clotting, additional arterial damagey during the procedure and allergic reaction to the material. All patients are placed on an anti-coagulance or thinner blood, after the procedure and then usually aspirin therapy is required indefinitely.

There is a possibility that the artery with the stent can collapse again or blocked again. This is referred to as restenosis. There are several stents called drugs that are covered with drugs that are released into the artery and help it prevent it from closing again. There are no known problems with the long -term presence of stents than the possibility of restenosis. Patients who have implanted stents will be carefully monitored by their cardiologist or another specialist for several weeks after the procedure and then at routine control intervals. Imagine magnetic resonanceg (MRI) Scanning is not recommended for at least four weeks after the procedure if it is not under direct supervision of a cardiologist.
