Nd:YAG laser has recently been widely used for the various vascular applications. This book presents basic vascular and tissue interactions in the Nd:YAG laser treatment of vascular lesions and prepares a guide for clinical use. Lesion diameter, colour, depth and pressure make the basis of the choice of laser parameters. Based on the research presented in this book, it is evident that lasers have been used increasingly as an alternative to surgical methods in the treatment of congenital and acquired vascular lesions. Clinical use of Nd:YAG laser presents a wide range of options to the practising physician in the treatment of different vascular lesions from easy to difficult.
