A stent is a small mesh tube that is used in the treatment of narrow or weak arteries. Your arteries are the blood vessels that carry blood away from your heart to other parts of your body.
Types of Stent Surgery:
A stent is placed in an artery as part of a procedure called percutaneous coronary intervention (PCI), also known as coronary angioplasty. PCI restores blood flow through narrow or blocked arteries, greatly increasing quality of life. A stent helps support the inner wall of the artery in the months or years after PCI.
Doctors also may place stents in weak arteries to improve blood flow and help prevent the arteries from bursting.
Stents usually are made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries.
Some stents are coated with medicine that is slowly and continuously released into the artery. These stents are called drug-eluting stents. The medicine helps prevent the artery from becoming blocked again.
Doctors may use stents to treat coronary heart disease(CHD). When plaque builds up in the arteries, the condition is called atherosclerosis.
Plaque narrows the coronary arteries, reducing the flow of oxygen-rich blood to your heart. This can lead to chest pain or discomfort called angina.
During the above-mentioned procedure PCI, a thin, flexible tube with a balloon or other device on the end is threaded through a blood vessel to the narrow or blocked coronary artery.
Once in place, the balloon is inflated to compress the plaque against the wall of the artery. This restores blood flow through the artery, which reduces angina and other CHD symptoms.
The aorta is the most important artery. It carries oxygen-rich blood from the left side of the heart to the body. This artery runs through the chest and down into the abdomen.
Over time, some areas of the aorta’s walls can weaken. These weak areas can cause a bulge in the artery called an aneurysm. An aneurysm in the aorta can burst, leading to serious internal bleeding.
To help avoid a burst, doctors may place a fabric stent in the weak area of the abdominal aorta. The stent creates a stronger inner lining for the artery.
Another problem that can occur in the aorta is a tear in its inner wall. If blood is forced into the tear, it will widen.
The tear can reduce blood flow to the tissues that the aorta serves. Over time, the tear can block blood flow through the artery or burst. If this happens, it usually occurs in the chest portion of the aorta.
An overnight stay in a hospital is usually required for this procedure. Before the procedure, your doctor may talk to you about medicines you’ll likely need to take after the stent is placed. These medicines help prevent blood clots from forming in the stent. This procedure usually takes about an hour.
Stents help prevent arteries from becoming narrow or blocked again in the months or years after PCI. However, stents aren’t a cure for atherosclerosis or its risk factors.
Making lifestyle changes can help prevent plaque from building up in your arteries again. Talk with your doctor about your risk factors for atherosclerosis and the lifestyle changes you’ll need to make.
Lifestyle changes may include changing your diet, quitting smoking, being physically active, losing weight, and reducing stress. You also should take all medicines as your doctor prescribes.
