Abstract
The optical parameters for the treatment of thromboangitis obliterans were presented. The penetration characteristics of 650nm laser diode interaction with human vessel and blood were also studied respectively. The extra-vascular irradiation instrumentation using 650nm diode laser was developed based on the above investigation, and it can be applied for the treatment of thromboangitis obliterans and other diseases. In clinical application, out of the 10 patients, including 7 males and 3 females that suffered from thromboangitis obliterans were treated with the extra-vascular irradiation instrumentation. 2 patients were suffered from upper limb, while the others were suffered from lower limb. Patient received 10 times treatment as a course, and the laser power for the first half-course was 20mW and ranged from 40mW to 80mW for the successively half-course. The total effective rate was 70 percent. A male patient in the third stage vasculitis of right foot without any improvement after treatment with traditional therapy but cured with diode laser irradiation after a course of treatment. The treatment mechanism of thromboangitis obliterans with diode laser was also briefly discussed.
