Endovenous laser treatment of varicose veins (EVLT) – a modern method of treatment of varicose veins. The procedure is based on thermal action on the inner walls of the expanded vessel, as a result of which it is glued and removed from the circulatory system. Gradually, the treated vein resolves, the skin above it is smoothed and acquires a natural color. The operation takes place without incisions, so there are no scars left after the operation.
Features of laser treatment of varicose veins
EVLT is one of the most effective methods of eliminating affected blood vessels. The operation is non-traumatic and bloodless, due to which it is carried out on an outpatient basis.
The essence of EVLT is the introduction of a thin laser conductor into an enlarged vein. The laser causes local “boiling” of venous blood, resulting in thermal cauterization of the inner surface of the vein. The walls of the vein collapse, so that gradually a connective tissue strand forms in place of the affected area, which is completely invisible externally. Since the laser guide is inserted into the vessel through a small puncture, no suturing or care is required after the operation.
Advantages of laser treatment:
- absence of pain and severe discomfort during the operation;
- a short rehabilitation period that does not require restriction of movements;
- absence of stitches, scars, hematomas and other cosmetic defects, excellent aesthetic result;
- the ability to return to normal life immediately after the procedure;
- the lowest percentage of postoperative complications compared to other methods of treatment of varicose veins;
- lifetime guarantee of the absence of relapses on treated vessels;
- no age restrictions.
Indications for the treatment of varicose veins with a laser
- failure of the valve apparatus of the vessels in combination with their deformation (expansion up to 10 mm);
- complications of venous insufficiency (trophic ulcers, thrombophlebitis);
- clinical manifestations of varicose veins (leg pain, swelling, cramps);
- pronounced cosmetic defect due to dilated subcutaneous veins.
If the patient has a significant expansion of the vascular walls (more than 10 mm), then endovenous laser coagulation is usually performed in combination with other surgical methods of treating the disease, for example, phlebectomy. For this reason, it is necessary to contact phlebologists when the first symptoms of varicose veins appear. In this case, surgical intervention may not be necessary.
Contraindications for the treatment of varicose veins with a laser
- heart diseases (ischemic disease, angina pectoris, arrhythmia);
- a recent stroke or myocardial infarction;
- thrombophilia (Latin thrombophilia) (tendency to form blood clots);
- dilation of the large saphenous vein by more than 18 mm;
- severe arterial insufficiency of the lower extremities;
- for women – the period of pregnancy and the first six months after childbirth;
- purulent-inflammatory skin lesions at the site of the intervention, etc.
In addition, the vascular surgeon will pay attention to chronic or concomitant diseases that require primary treatment.
Ultrasound of blood vessels. As a rule, a phlebologist performs an ultrasound examination in order to assess the length, bend, and other characteristics of the affected vessels. Along with this, the doctor performs duplex scanning of the veins and arteries of the lower extremities to detect blood clots, atherosclerotic plaques, vascular spasms, and other pathologies.
Standard preoperative preparation. As before any other surgical intervention, the patient will have to do an ECG, undergo fluorography and laboratory blood and urine tests, as well as get a therapist’s consultation.
Preparation for the EVLT
Consultation of a phlebologist. If the patient is taking medications that affect the blood clotting system (hormonal contraceptives, aspirin, etc.), it is necessary to tell the doctor about it. The specialist will adjust the schedule of their admission taking into account the upcoming operation.
Preparation on the day of the procedure. The patient should refrain from eating and drinking 4 hours before surgery. It is also necessary to wear loose clothing since compression stockings will be required immediately after the intervention. If necessary, the doctor will provide the patient with individual advice on preparation.
