METHOD OF ENDOVENOUS OBLITERATION OF MAIN SUBCUTANEOUS VEINS Russian patent published in 2018 - IPC A61M25/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to vascular surgery. Method includes puncturing of the trunk, inserting into the lumen of the vein a radio-frequency catheter and its positioning under ultrasound control, followed by radio-frequency treatment of the vein during the reverse traction. Radio-frequency treatment is carried out at a temperature of 80 °C in one cycle of exposure, achieving reduction of the vein by 45–50 % in diameter. After completion of radio-frequency treatment of the entire vein, foam sclerosant is immediately injected therein until it is completely obliterated under ultrasound control.

EFFECT: method enables obliteration of the trunk of subcutaneous veins with a diameter of more than 10–12 mm, while maintaining the principles of low traumatism and preventing possible complications, without carrying out tumescent anesthesia.
