Vein ligation is a minor surgical procedure where a large varicose vein is tied off through a small incision. This is necessary when veins are not working properly and the blood in them is leaking (refluxing) back down the leg. These incompetent veins are the source of most of the visible varicose veins seen on the surface of the leg. That is why treating only the surface veins will not eliminate the source of the problem and will only lead to a poor result or a rapid recurrence of the original or a new problem. Ligation is performed in combination with ambulatory phlebectomy and/or sclerotherapy which eliminates the source and the surface diseased veins.
