980nm 1470 nm Diode Laser

DOD Diode Laser provides various treatment options with a 600 micron optical fiber, a guide wire introducer sheath, and a needle for percutaneous perforation.

Operating Steps:

1. Prior to treatment, the SFJ and GSV are mapped through the use of color duplex ultrasound.

2. The guide wire introducer sheath is introduced into the GSV at knee level or the lower part of the thigh.

3. The fiber is advanced via the introducer sheath until the fiber tip is positioned 1-2 cm distal to the SFJ.

4. A red guiding light emitted from the fiber tip provides a helpful indication of the tip position. Prior to release of the laser beam, the exact tip position is controlled carefully by use of ultrasound.

The method has been well tolerated by the majority of the patients treated, with only occasional feelings of heat during treatment.

Most patients show mild ecchymosis and occasional mild induration and paresthesia in the area of anaesthetic infiltration. It is expected that the undesired side-effect incidence will decrease as the operators gain more experience in the use of this new technique. The results were evaluated by the physicians as well as patients.
