Treatment of essential telangiectasia: effects of increasing concentrations of polidocanol.
A double-blind, double-paired comparison study was performed to evaluate the effects of increasing concentrations of polidocanol in the sclerotherapy of essential telangiectasias of the legs. Polidocanol 0.25%, 0.50%, 0.75%, and 1.0% were compared with regard to clinical effectiveness, safety, and patient acceptance. All dosages were well tolerated by the patients. There were no allergic reactions to polidocanol and no cases of superficial ulceration nor necrosis. Among those whose veins cleared, there was little difference in time to clearing for the four concentrations, which averaged three to four treatment sessions. No statistically significant differences existed among the four dosages with respect to level of improvement, itching, or neovascularization. Polidocanol 0.75% and 1.0%, however, caused more side effects noted by patients and induced more hyperpigmentation than did the lower concentrations. Polidocanol 0.25% yielded the lowest percentage of patients whose veins cleared. The 0.50% solution was the most effective concentration for total overall clearing of the types of vessels treated in this study. From this information it appears that 0.50% polidocanol may be the sclerosing agent of choice.[1]References
