Experience in treating 351 patients with persistent wounds and trophic ulcers by low-intensity laser radiation in out-patient clinics is generalized. Complete epithelialization of the wound or ulcer surface occurred in 236 patients. There were 246 patients aged 60, all were treated without leave from work. Thus, the inclusion of laser therapy in the complex of measures for persistent wounds and trophic ulcers is a highly effective method which may be applied in preoperative management and which will reduce considerably the term of in-patient treatment.
