Why is performed coronary stenting?
Heart in the body acts as a powerful pump,allowing blood to circulate constantly, bringing to the tissues and organs are so necessary for their livelihoods oxygen and nutrients. But to carry out this great work the heart also needs these components, their delivery through an extensive network of coronary arteries. But if these vessels pathological changes occur, for example, there is a proliferation of layering and cholesterol deposits, connective tissue, calcium salts (calcification), the vessel walls are deformed, lumen gradually more and more narrowed. This phenomenon is called stenosis. The heart begins to suffer from lack of blood supply, less doing its job. The chest pain attacks occur periodically, tachycardia. dyspnea, Excessive sweating, even fear appearsof death. Restore blood flow in the affected artery, doctors can not only using the bypass, but also resorted to a less traumatic method - vascular stenting. For this special implanted coronary stent. He is a thin, consisting of a metal tube wire cells, bloated special balloon. When the stent is introduced in the affected vessel, then expanding when it is pressed into the vessel wall, the lumen is expanded. In this manner it manages to improve the supply of the heart muscle with blood.
Indications for the implementation of the stent may be:
- asymptomatic myocardial ischemia;
- exertional angina or rest;
- acute myocardial infarction (The operation is carried out in the first hours after the onset of disease);
- restenosis (i.e. re-stenosis has developed to the point where the stent has been placed previously);
- CABG (coronary artery bypass grafting) if angina resumed;
- acute stent thrombosis, which developed after stenting conducted.
The first such operation with the introduction of the stent through the skin were performed in 1986 in France and Switzerland.
How is the vascular stenting?
mymedinform.com mention the complications possible during the stenting.
- The response of an allergic reaction when ingested radiopaque substance.
- Thrombosis and restenosis at the site of the stent.
- Abnormalities in the kidneys.
- Damage to the artery wall.
- Irregular heartbeat.
- Myocardial infarction.
- The lethal outcome (extremely rare).
- The formation of hematoma at the site where the puncture is made.
- Bleeding in the puncture area.
- The pulsating hematoma (cavity joined to the artery).
- Education between the artery and vein running.
On the results and recommendations
Usually in most cases resultsstenting of the coronary vessels is positive. The rehabilitation period is short, soon the patient can begin to previously performed duties. And only 15-20% of the total number of patients operated on by this method once again there is a narrowing of the lumen in the vessel. But cardiologists continue to improve stents and equipment operation, to reduce the rate of statistics, save the patient from heart problems.
To prevent the formation of blood clots in the arteries, stenting zone, as well as slow down the process atherosclerosisNecessarily have to take the following medications:
- Clopidogrel (Plavix is its synonym) - not less than 12 months after surgery.
- Aspirin (Synonymous with acetylsalicylic acid) - the period of reception of preparations containing acetylsalicylic acid, sold under various names, is quite lengthy, it sets a doctor.
- Statins (they are needed at a high rate cholesterol).
Your doctor may prescribe other medicines - it all depends on the state of health of the patient.
Eat right, limit foods abundant with cholesterol.
Pay attention to the condition of your heart, notoverload themselves excessive, unbearable physical exertion, are under the supervision of a cardiologist. If a person is having a stent, suddenly a doctor may prescribe an MRI, be sure to warn the technician who will carry out the survey, you have the stent. Check with your cardiologist, what type of stent you have installed. The instructions for each stent always specify the period during which it is necessary to refrain from MRI.
vascular stenting is currently consideredcardiologists with one of the most effective and successful ways to eliminate the narrowing of the coronary arteries. It is low-impact (no need to open the sternum). Suffice it to puncture size of 2 mm at the point where the catheter will be introduced. The entire procedure takes about 40 minutes. This operation is performed under the quota (VTMP system) or on toll conditions.
