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.
