Physicians at Saarland University hospital in Germany assigned 400 patients to one of the two procedures. The patients had all been diagnosed with chronic venous insufficiency of the saphenous vein that runs from the hip to the toe.
Two years later, the physicians found that of the 316 patients who could be reached, 123 patients had developed new varicose veins. Of those patients, 51 patients had received laser treatment and 72 had undergone surgery.
Ultrasound reports revealed that 18 percent of patients who received laser treatment experienced a backflow of blood where the saphenous vein connects to the femoral vein, compared to just 1 percent of those who had surgery.
According to the report, while patients who undergo laser treatment may be more satisfied with the cosmetic results, the complications are much more severe than those that occur after surgery.
