Endoscopic stenting: the lumen of the organ

About the service

The K+31 medical centers perform the procedure of vascular stenting. Using a modern endovascular method, a vascular surgeon restores the patency of narrowed or plaque-clogged areas. During the operation, a metal frame is installed. The choice of stent by material, opening method, 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 only needs to make a puncture (puncture) and install a special catheter.

Types of stents

Endoscopic stenting procedure

A stent is a wire tube that serves as a frame and helps maintain the lumen of an artery. The following types of stents are currently used in vascular surgery:

  • Bare metal stent
  • Drug-eluting stent, which prevents closure and re-narrowing of the vessel lumen
  • A stent made of a soluble material that completely dissolves in 6-9 months

The first two types of stents can interfere with the natural movement of the artery. During coronary artery bypass grafting, the metal frame in the vessel interferes. Therefore, after stenting, the patient is prescribed medication to prevent clot formation.

General information

Indications for Stenting

Stent placement at the lesion site is recommended for the following diseases and conditions:

  • Coronary heart disease
  • Atherosclerosis
  • Angina
  • Increased risk of heart failure
  • Stenosis
  • Tumors of internal organs that obstruct blood flow or the passage of food
  • Injuries to large vessels and digestive organs

Most often, the intervention is performed on the cardiovascular system. Additionally, indications for stenting may include conditions affecting the following body parts:

  • Gallbladder (biliary tract) and liver
  • Intestines and stomach
  • Esophagus

With proper preparation and surgery, patients recover quickly and return to normal life, significantly reducing the risk of complications. The procedure is widely used in many areas of medicine to effectively treat complex conditions.

Contraindications to the procedure

Although the procedure is considered safe and there are no absolute contraindications to cardiac stenting, it is not suitable for everyone. Here are the main situations when doctors recommend avoiding the procedure:

  • Active infection of any origin
  • Bleeding disorder
  • Intolerance to anesthesia
  • Chronic liver, kidney, lung, or nervous system diseases
  • Heart failure
  • Structural vascular abnormalities or large aneurysms

Before deciding on surgery, the doctor will assess the patient's overall condition.

Preparing for the Procedure

To ensure successful treatment, it is important to prepare in advance and undergo a full medical examination. The main stages of preparation for stenting:

  • Specialist consultation - the doctor will ask the patient detailed questions about all symptoms, medical history, and previous surgeries.
  • Ultrasound - ultrasound imaging allows us to visualize the structure of blood vessels and identify areas of narrowing or impaired blood flow.
  • CT and MRI scans - help to thoroughly examine the condition of blood vessels and surrounding tissues.
  • Blood tests.
  • Electrocardiogram - shows heart function.

Many medical centers in Moscow, including the K+31 Clinic, offer comprehensive preparation for stenting. The more accurate the diagnosis and the better the patient's health is assessed, the lower the risk of complications after surgery.

How is stenting performed?

A stent is a thin, tube-like frame made of a special hypoallergenic metal alloy or plastic. It is initially folded, which facilitates the stenting procedure—the surgical insertion of a stent into an area of the organ that is narrowed and requires expansion.

Stenting is performed in a hospital setting under sedation, minimizing discomfort and discomfort for the patient.

Stenting is performed under dual control—radiographic and endoscopic—to ensure maximum precision. The exact time required depends on the location of the narrowing and the type of stent. On average, the procedure takes 30-45 minutes. Stent placement steps:

  • Puncture at the catheter insertion site
  • Next, a guidewire is inserted through the needle. The needle will be replaced with an introducer sheath through which the catheter is guided.
  • The following instruments are inserted through the catheter: a microguidewire for navigation and contrast. The movement of the guidewire is displayed on the X-ray screen.
  • The vascular surgeon determines the exact location of the vessel blockage. The stent is delivered to the damaged area using the microguidewire.
  • After placement, the balloon inside the stent is inflated. The metal frame expands within the vessel, pressing the plaque against the walls. The balloon is then deflated and removed.

After the surgery, the patient is given a protocol that carefully describes all the steps performed during the surgery, as well as the type of stent installed.

Stenting can be performed to provide temporary assistance before subsequent radical surgical intervention or, if radical treatment is not indicated, as a definitive treatment method.

Rehabilitation after Stenting

Immediately after discharge from the hospital, the rehabilitation period begins, during which it is necessary to follow a number of important recommendations. A key aspect of recovery is proper nutrition. After stenting, it is advisable to follow a diet rich in vitamins and minerals, avoiding fatty, salty, and sugary foods.

Moderate physical exercise is beneficial for strengthening the heart and improving overall well-being. Therefore, successful recovery after stenting depends on following doctor's recommendations, proper nutrition, and regular clinical monitoring.

Possible complications after stenting

As with all surgical procedures, stenting carries a risk of complications such as:

  • Bleeding
  • Organ perforation
  • Stent migration (displacement)

These complications are relatively rare, but require immediate treatment. Therefore, patients undergoing stenting should be monitored in the hospital for the early postoperative period (2-3 days).

Benefits of stenting

  • Efficiency. Pain immediately disappears after stent placement. The metal frame remains in place, preventing the vessels from narrowing again and maintaining normal blood flow.
  • Safety. Small punctures reduce the risk of bleeding, shorten the recovery period, and prevent post-surgical complications.
  • Fast recovery. After stenting, the patient remains in the hospital under specialist observation for no more than 5 days.
  • The surgery reduces the risk of recurrent myocardial infarction and significantly improves quality of life.

Today, stenting is becoming one of the main treatments for vascular and heart diseases. This method is virtually painless and requires minimal surgical intervention.

Instead of open surgery, thin catheters are used—this approach is called minimally invasive and reduces the risk of complications. A second important advantage is rapid recovery. Furthermore, the procedure is highly safe—the operation is carried out under the supervision of the center's experienced specialists.
