[Percutaneous laser-induced thermotherapy of nodular goiter]

Substantiation of use of laser radiation Nd:YAG (1064 nm) and diode (805 nm) for destruction of thyroid tissue was the purpose of this study based on experimental research of reparative and adaptive processes in thyroid gland. The influence of high-intensity laser radiation was studied in vivo in thyroid gland of 41 dogs. The optimal modes of laser radiation ensured focal destruction of thyroid gland without damage of surrounding organs were selected. The developed modes were used in the treatment of 18 patients with recurrent nodal and multinodal euthyroid goiter. Exposure was performed by puncture method without denudation of thyroid gland. There were no complications during irradiation and nearest postoperative period. In dynamic ultrasonic examination over 2 years the decrease of nodes sizes was revealed in all the patients.
