980 nm laser endo-perivenous treatment of lower limb reticular veins and telangiectasias. Technical notes.

ABSTRACT

INTRODUCTION: For several years, the venous aesthetic problem has been tackled mainly with sclerotherapy techniques. In recent years, laser techniques have been added, both surface (transdermal) and endo-perivenous, performed with small optical fibers (100-200 µm) and low intensities in terms of LEED and Watt. The endo-perivenous technique has extended the possibilities of laser treatment also to the nourishing veins, to telangiectasias resistant to therapies with sclerosing agents and/or transdermal lasers and to vessels with larger diameters (1-3 mm) and depths >1.3 mm. MATERIALS AND METHODS: We report a series of 20 patients affected by reticular veins and telangiectasias of the lower limbs (CEAP C1-2) treated with endo-perivenous technique. The most used setting was 3 W (range 2-4 W) with a mean fluence delivered of 11.25 J/cm (range 6-18) in pulse mode with 980 nm laser, 200 µm fiber after a preventive skin cooling. Scheduled follow-up occurred 20 and 60 days after treatment. RESULTS: Total technical success, understood as complete obliteration of all treated vessels, was achieved in 70% of cases (14/20) after just one treatment. The most observed early local complications were erythema, vesicles, and small cutaneous eschars that regressed in 3 weeks. At 60-day follow-up, just one complication was observed a small area of hyperpigmentation (5%). In this case, chemical peel procedures was performed with good clinical results. CONCLUSIONS: Endoperivenous laser treatment represents an effective and valid tool for the treatment of teleangectasias and reticular varicose veins.
