Varicose veins can be caused be weakened valves in the veins or weakened walls of the veins, or by inflammation in the veins (phlebitis).
Typical varicose vein surgery involves a scalpel incision, and then a large needle and sheath pass a laser catheter into the blood vessel. This can leave small scars, especially on dark skin.
David Greuner, M.D., a cardiovascular surgeon at NYC Surgical Associates explained, “When these people have a lot of venous disease and require a lot of little incisions, it can lead to quite a disfiguring result on somebody that wants their legs addressed for cosmetic reasons as well.”
Dr. Greuner has invented No Knife. It uses only a much smaller needle, containing a very thin laser fiber that contracts and repairs the vein, a stark contrast in the two needle sizes and in the scarring results.
Varicose veins can form anywhere in the body, but they are most often located in the legs.
