Endovenous laser treatment (EVLT) is a minimally invasive procedure used to treat varicose veins, a condition characterized by enlarged, twisted veins usually found in the legs. The procedure involves the use of laser energy to close off and seal the affected veins. During EVLT, a thin, flexible catheter is inserted into the varicose vein through a small incision in the skin. A laser fiber within the catheter emits laser energy, which is directed towards the vein's inner walls. This energy causes the vein to heat up, leading to its closure and eventual absorption by the body over time. Endovenous laser treatment is often recommended for patients with symptomatic varicose veins, such as pain, swelling, or skin changes, and is particularly effective for treating larger veins that are not responsive to conservative treatments like compression stockings. The procedure is performed under local anesthesia, making it relatively comfortable for the patient and allowing for a quick recovery. Despite its advantages, EVLT does come with potential complications. These can include bruising, swelling, or pain at the site of the laser treatment. There is also a risk of skin burns or thermal injury if the laser energy is not precisely controlled. Additionally, some patients may experience pigmentation changes or the formation of small blood clots. In rare cases, there may be a risk of deep vein thrombosis or recurrence of varicose veins. Overall, endovenous laser treatment is considered a safe and effective option for managing varicose veins, providing significant symptom relief and cosmetic improvement with minimal invasiveness.
