Physical properties of laser irradiated sclerosing foams

摘要

The Polidocanol microfoam sclerotherapy is a potential treatment of venousdisease. Recently, four years conducted clinical trials confirm that the Polidocanolmicrofoam injections assisted by pulsed Nd:YAG laser therapy improves the cure"efficacy. Started from these, laser beams interaction of liquid as well as microfoamPolidocanol was investigated. Results regarding the elements that may influence thefoam stability of the sclerosing agent are discussed. The foam stability is increasingwith the increment of sclerosant" concentration and with the increase of air percentage.The FTIR spectra suggest molecular structure changes of foam comparing with liquidpolidocanol in both unirradiated/irradiated samples.
