The K+31 medical centers perform the procedure of vascular stenting. Using a modern endovascular method, the vascular surgeon restores the patency of narrowed or blocked areas by plaques. During the operation, a metal frame is installed. The choice of stent based on material, deployment method, and diameter depends on the person’s condition.
The X-ray endovascular stenting method is considered the most effective method of therapy for coronary heart disease. Minimally invasive intervention helps prevent ischemic stroke in atherosclerosis and stenosis. The operation is performed without cutting the chest. The surgeon just needs to make a puncture (puncture) and install a special catheter.
- Efficiency. After installing the stent, the pain immediately disappears. The metal frame remains and does not allow the vessels to narrow back and maintains normal blood circulation
- Safety. Small punctures reduce the risk of bleeding, shorten the rehabilitation period, and eliminate complications after surgery
- Fast rehabilitation. After stenting, the patient remains in the hospital under the supervision of specialists for no more than 5 days
- Surgery reduces the risk of recurrent myocardial infarction and allows a person to significantly improve their quality of life
A stent is a wire tube that serves as a frame and helps maintain lumen in the artery. Today, the following types of stents are used in vascular surgery:
- Metal stent without covering
- Drug-eluting stent that prevents overgrowth and re-narrowing of the vessel lumen
- A stent made of soluble material that completely dissolves after 6-9 months
The first two types of stents can disrupt the natural vibration of the artery. During coronary bypass surgery, the metal frame in the vessel “gets in the way.” Therefore, after stenting, the patient is prescribed medication to prevent the formation of clots.
Installation of a stent at the site of the lesion is recommended in the presence of the following diseases:
- Ischemic heart disease
- Vascular atherosclerosis
- Angina
- Increased risk of heart failure
There are no absolute or relative contraindications to stenting of cardiac vessels.
The stent is a thin frame in the form of a tube, which is made of a special anti-allergenic metal alloy or plastic. Initially, it is in a folded state, which facilitates the stenting procedure - an operation to insert a stent into an area of the organ that is narrowed and requires expansion.
Stenting is performed in a hospital setting, under medical sedation, due to which the patient’s discomfort and discomfort are reduced to a minimum.
Stenting is performed under double control - x-ray and endoscopic, so that all actions are as accurate as possible. Exactly how much time will be spent depends on the location of the narrowing zone and the type of stent. On average, the manipulation takes 30-45 minutes. Stages of stent installation:
- Puncture in the catheter insertion area
- Next, a conductor is inserted through the needle. Along it, the needle will be replaced with an introducer, through which the catheter is guided
- The following instruments are inserted through the catheter: a microconductor for navigation and contrast. The movement of the conductor is displayed on the screen of the X-ray machine
- The vascular surgeon determines the exact location of the blockage in the vessel. The stand is delivered to the damaged area via a microconductor
- After installation, the balloon inside the stent begins to inflate. The metal frame diverges in the vessel, pressing the plaques against the walls. Afterwards the balloon is deflated and removed
After the operation, the patient is given a protocol that carefully describes all the steps performed during the operation, and also describes the type of stent installed.
Stenting may be performed to provide temporary relief before subsequent radical surgery or, if radical treatment is not indicated, then as a definitive treatment.
Appointment to the doctor
As with all surgical interventions, with stenting there is a risk of complications such as:
The listed complications are rare enough, but require immediate treatment. That is why patients after stenting in the early postoperative period (2-3 days) should be observed in a hospital.
