The influence of different types of low-intensive laser radiation to healing of venous trophic ulcers in lower extremities

The influence of three types of low-intensive laser radiation to healing of lower extremities venous trophic ulcers in 82 patients was estimated (class VI, CEAP classification): the continuous radiation helium-neon laser (subgroup I), the modulated infrared laser radiation (subgroup II) and the combined laser radiation (pulse infrared radiation and continuous radiation of visible range) (subgroup III). The therapeutic laser devices such as "AFDL-1" (wavelength – 0,63 microns), "Scalar-1/40" (wavelength – 0,89 microns) and "Ulan-BL-20" (lengths of waves: 0,44; 0,52; 0,57; 0,64 and 0,89 microns) were used for conservative treatment of trophic ulcers. The planimetric methods such as evaluation of the ulcer defects area and speed of its epithelization in dynamics were used for objective comparison of different types of laser radiation efficiency. Due to this treatment in all patients the complete healing of trophic ulcers was achieved. In patients of subgroup I the average speed of epithelization was 0,26 ± 0,05 cm²/days, in patients of subgroup II – 0,17 ± 0,06 cm²/days, in patients of subgroup III – 0,33 ± 0,05 cm²/days. The advantages of laser radiation in the visible range in isolated (helium-neon laser) and combined options are revealed. The best results are received in case of combined laser radiation generated by portable devices which provide distribution of low-intensive laser radiation within all effected tissues. The combination of traditional medical methods with combined laser radiation is expedient in conservative treatment of lower extremities venous trophic ulcers.
