Article08. 05. 2024 Angiology and Venous Surgery
Endovenous laser therapy (EVLT) is a modern thermic, minimally invasive method used for removing varicose veins. This technique uses thermal destruction to seal off damaged veins, thus improving blood flow and alleviating the symptoms associated with varicose veins. Thanks to its effectiveness and patients’ rapid recovery, EVLT has become a popular alternative to traditional surgical methods.
For whom the method is appropriate
EVLT is appropriate for patients who suffer from moderately severe to severe varicose veins. It is especially beneficial for those who have problems with pain, swelling or feelings of heaviness in the legs, in treating chronic venous insufficiency, and in the case of aesthetic requirements associated with visible varicose veins. A doctor assesses the suitability of this method on the basis of the patient’s overall health condition, the extent of damaged veins and, as the case may be, previous treatment. In the case of a greater extent of lateral varicose veins, supplementation with a phlebectomy or sclerotisation may be considered. Such supplemental measures can be carried out either in the course of the procedure or a few months after the procedure.
Course of the procedure
The procedure is performed on an outpatient basis under local, tumescent anaesthesia. Treatment begins with a detailed ultrasound examination of the venous system. A thin catheter is then inserted into the affected vein under local anaesthesia. Using a laser, the wall of the vein is heated, which causes the vein to close and gradually perish. The treated vein is coated with an anaesthetic solution. The whole procedure takes approximately 30-45 minutes and patients can go home after a brief period of rest.
Benefits of the procedure
- Rapid recovery: Without the necessity of hospitalisation, minimal post-operative pain.
- Without restrictions: Most patients return immediately to their normal activities and work duties.
- Lower risk of complications: In comparison with traditional surgical methods, EVLT has a lower risk of complications such as bleeding and infection.
- Aesthetic improvement: This method not only improves functional symptoms, but also significantly improves the appearance of the affected limbs.
