A stent is a small expandable tube that is inserted in a weak or narrow artery to improve blood flow. It may also be used in other hollow areas of the body including the urinary tube. Stents are either made of a metal or plastic mesh or fabric. Fabric stents (also known as stent grafts) are used in larger arteries. Some stents may also be coated with medicine which is slowly released into the arteries to prevent them from being blocked again.
Stents help arteries and blood vessels to stay open and prevent cardiac arrest. Coronary or cardiac stents are the more commonly used and may treat a variety of heart conditions including:
Stents may also be inserted in the arteries to the kidneys as blockages here can affect kidney function. They are sometimes used for arteries in the limbs of patients with peripheral artery disease (P.A.D.), a condition in which severe arterial narrowing can cut off blood flow and result in the patient requiring surgery.
As mentioned earlier, stents are also used in other areas of the body such as to hold open a damaged or blocked ureter, bile ducts or airways.
A stent becomes a permanent part of your artery or any other area where it is inserted. Here is what a typical cardiac stenting process involves:
A stent may eliminate the need for a coronary bypass surgery. It is a minimally invasive alternative to coronary artery bypass grafting and has a faster recovery period as well. Patients are able to leave the hospital in a day and can quickly return to their normal activities when compared to the typical six-week recommended recovery after a bypass surgery. Most patients do not require general anesthesia for this procedure.
It is important to understand that although a stent can bring about a significant improvement in your condition, it is not a cure for heart disease. You will still need to monitor and manage other health conditions, if any, and maintain a healthy lifestyle.
