Laser Treatment of Leg Veins 

Laser Treatment of Leg Veins 

 Public interest in laser and light treatment of leg veins is high, and, under the right circumstances, excellent results can be achieved with this treatment modality. With any laser or light source treatment, reverse pressure from associated reticular or varicose veins must be recognized and eliminated; otherwise, the treatment is doomed to fail. Many patients benefit from a combination of treatments such as sclerotherapy, ambulatory phlebectomy, and intravascular laser or radiofrequency closure because external lasers and light sources do not effectively treat associated reticular and varicose veins. Lasers can be effective in treating vessels of less than 1-2 mm in diameter that are resistant to sclerotherapy and telangiectatic matting, which can occur postsclerotherapy. However, sclerotherapy remains the criterion standard for the treatment of leg veins and telangiectasias. 

Not until the development of the pulsed dye lasers (PDLs) in the late 1980s were the first reasonable results achieved on leg veins. [123Development over the last decade of longer wavelength, longer pulse duration pulsed lasers and light sources has greatly improved outcomes. Basic requirements for a laser or a light source to treat leg veins are a wavelength that is proportionately better absorbed by the target (hemoglobin) than surrounding chromophores and penetration to the full depth of the target blood vessel. Sufficient energy must be delivered to damage the vessel without damaging the overlying skin, and this must be delivered over an exposure time long enough to slowly coagulate the vessel and its lining without damaging surrounding tissue.
