Diagnosis and Treatment of Venous Diseases

The treatment of leg telangiectases with the carbon dioxide or argon laser results in a low success rate and an unacceptable risk of scarring. Sclerotherapy is effective; however, pigmentation and telangiectatic matting induced by extravasation of RBCs and excessive posttreatment inflammation are common. We conducted a clinical and histologic study of therapy with the 585 nm pulsed dye laser alone and in combination with subtherapeutic sclerotherapy in the rabbit ear vein model. The pulsed dye laser alone was effective when 10 joule/cm2 was used. In combination with immediate injection of the sclerosant, effective endosclerosis occurred with all tested laser energies (8 to 10 joule/cm2).
