Balloon angioplasty

Balloon angioplasty is a minimally invasive procedure used to treat narrowed or blocked blood vessels (arteries). The main goal of angioplasty is to restore normal blood flow in the arteries, which helps reduce symptoms such as chest pain (angina) and prevents serious complications, including myocardial infarction.

The method involves inserting a catheter with a small balloon at its tip into the affected vessel. The balloon is inflated at the site of narrowing, widening the artery and restoring blood flow.

When is balloon angioplasty performed?

1. Coronary artery disease (CAD). For the treatment of angina caused by narrowing of the coronary arteries.
2. Acute myocardial infarction. Emergency angioplasty helps rapidly restore blood flow in the affected artery.
3. Peripheral artery disease. Narrowing of the arteries of the legs leading to pain during walking or the formation of ulcers.
4. Renal artery stenosis. To improve blood flow to the kidneys and help control arterial hypertension.
5. Preparation for other procedures. In some cases, angioplasty is performed prior to stent placement to ensure access to the narrowed segment of the vessel.

Advantages of balloon angioplasty

1. Minimally invasive technique. The procedure is performed without large incisions, using only a small arterial puncture.
2. Rapid recovery. Patients can usually return to normal daily activities within a few days.
3. Effective treatment. Rapid restoration of blood flow reduces the risk of heart attack and relieves symptoms.
4. Can be performed in emergency situations, such as acute myocardial infarction.

How is the procedure performed in Belarus?

Patient preparation. Before balloon angioplasty, the patient undergoes a series of preliminary examinations, including ECG, blood tests, and angiography (X-ray imaging of blood vessels using a contrast agent). The procedure is usually performed under local anesthesia, which minimizes discomfort and procedural risks.

Procedure stages

1. A guidewire and catheter are introduced through a small puncture in the femoral or radial artery and advanced toward the coronary artery.
2. Under X-ray guidance, the catheter with a balloon at its tip is positioned at the narrowed segment of the artery.
3. The balloon is inflated, widening the artery and compressing atherosclerotic plaques against the vessel wall, thereby improving blood flow.
4. After vessel expansion, the balloon is deflated and removed, and the catheter is withdrawn.

If stent placement is required. In some cases, after balloon dilation, a stent—a metallic mesh framework—is implanted to keep the artery open and prevent recurrent narrowing.

Recovery after angioplasty

1. Post-procedural monitoring. The patient remains under medical supervision in the hospital for several hours or up to one day to prevent potential complications.
2. Physical activity. During the first few days after the procedure, heavy physical exertion and intense activity should be avoided.
3. Diet and lifestyle. Patients are advised to follow a heart-healthy diet, stop smoking, and engage in regular physical activity to prevent recurrent arterial narrowing.
4. Medication therapy. After the procedure, blood-thinning medications (anticoagulants and antiplatelet agents) and cholesterol-lowering drugs are prescribed.

Effectiveness and long-term outcomes

1. After angioplasty, most patients experience significant improvement, including reduced chest pain, increased physical activity, and better exercise tolerance.
2. The procedure significantly lowers the risk of myocardial infarction by improving coronary blood circulation.
3. In some cases, repeat angioplasty or stent placement may be required if restenosis develops, necessitating further intervention.

Balloon angioplasty is an effective method for treating arterial narrowing, helping to restore blood flow and improve patients’ quality of life. The procedure is particularly beneficial for coronary artery disease and in emergency situations such as myocardial infarction. Adherence to medical recommendations, a healthy lifestyle, and regular follow-up care help prolong the therapeutic effect and minimize the risk of complications.
