Abstract


Background. Endovascular laser coagulation (EVLT) is one of the modern methods of treatment of patients with varicose veins of the lower limbs, but requires its improvement. Objective: to perform a comparative assessment of the effectiveness of EVLT with different radiation power at certain varicose veins clinical course, to identify prognostic criteria. Materials and methods. The study included 263 patients (64 men and 199 women aged 29 to 72 years), who underwent low power EVLT (7–10 watts) in 57 % of cases and high (15 watts) — in 43 %. Results. Low-power EVLT of vessels in patients with varicose veins of the lower extremities was performed less frequently in cases of previous phlebothrombosis, hypertension, changes the surface viscosity of venous serum, smaller energy parame­ters on the length of striping and the area of the vascular intima, but in the group with the same observations according to the disease class severity, comorbidity and background of drug therapy the effectiveness of medical actions in two and four weeks after surgery in patients with a low-power laser ablation was higher, and the total vein occlusion was observed in 80 % more frequently, that was determined by pre-estuarine expansion of veins, roughness in its tube course, presence of comorbid second type diabetes and gonarthrosis, administration of rivaroxaban and low molecular weight heparins. Conclusions. The low-power EVLT in varicose vein of lower limbs is highly effective, but requires certain indications for its use.
