Varicose vein laser treatment has some efficacy and is a minimally invasive treatment, but there is a recurrence rate. Laser treatment of varicose veins involves puncturing a fiber optic into the main trunk of the saphenous vein and using high temperatures to cauterize the wall of the varicose vein, causing aseptic inflammation to form, and ultimately mechanizing the lumen of the blood vessel to close completely, resulting in the cure of the varicose vein. As the large vein trunks close under laser cauterization, the pressure on the veins of the lower extremities can be reduced to a great extent, and at the same time, with the foam sclerotherapy of varicose veins of the lower extremities, a better therapeutic effect can be achieved. However, it should be noted that if the operator retreats the fiber too quickly during the operation, local lumen residue may be formed, leading to recurrence; at the same time, the laser treatment, due to the generation of high temperature, burns the main trunk of the saphenous vein and the surrounding tissues, and in severe cases, local skin necrosis may occur. For the choice of varicose vein treatment, it is recommended to consult with the attending physician for standardized treatment under the doctor’s guidance.
