Radiofrequency ablation is now considered a kinder and easier to use technique for removing varicose veins. Many laser treatments for varicose veins are expensive and time consuming, which is why physicians are urging many patients to use radiofrequency procedures. Over 25 million people are adversely affected by varicose veins and spider veins, which is why a gentle and efficient procedure would alleviate much pain and time constraints with traditional removal methods. MedPage News said, "In a randomized trial, pain and tenderness, skin discoloration from bleeding in the treated area, and quality of life significantly favored radiofrequency ablation in the first weeks after treatment, J. Andrew Williamson, M.D., of the Dotter Interventional Institute in Portland, and colleagues found. Radiofrequency treatment applies heat targeted directly at the vessel wall to contract collagen and damage the endothelium with delayed inflammation and fibrosis that closes the vessel."
