Stents are medical devices that are placed in narrowed segments in the coronary arteries and allow the intravascular blood flow to return to normal. They are in the form of a cage and are available in different sizes between 2-4 mm diameter and 10-36 mm length. It is used in the treatment of vascular occlusions. Stents are available shrunk over a balloon. These stents are delivered through the patient’s vascular access to the narrowed area. Meanwhile, the balloon in the stent is inflated and the vascular access is opened. The stent is embedded in the vein together with the opened balloon. The balloon is then deflated and removed from the vascular access. Although it is not possible for the stent embedded in the vein to be dislodged, it remains for life.
The stenting procedure increases blood flow to the heart. Narrowed or blocked vessels are opened with stenting, but it does not treat cardiovascular disease alone. In addition, you should continue to use drugs that slow the progression of the disease and make changes in your lifestyle. Some vessels cannot be stented. In this case, surgery or drug treatment can be selected according to the clinical and vascular structure.
A metal stent is a mesh made of metal wire. Medicated stents, on the other hand, are a special drug coating on the metal wire. After this medicated stent is inserted, the drug on the wire begins to be slowly released into the tissue. By affecting the tissue here, it prevents narrowing and congestion. Fusible stents are made of a molten material, not metal. Each of these stents is used in different situations. Which stent should be placed is decided by a detailed examination by the doctor.
After the stent is placed, the patient should be very careful about his daily life and nutrition. The 6-month period after the stent application is a period that needs attention. It is necessary for the healing process to follow the medications given by the doctor and the recommendations given by the dietitian in order to prevent the veins from narrowing or clogging again. In line with this list, the patient is informed about what to eat or what not to eat, and the healing process is accelerated.
