Experimental: Class 1 (18-21 mm Hg at the ankle level) above-knee graduated compression stockings

All participants will undergo measurement of the affected limb at standard points to select the appropriate size of compression stockings. Then, the clinical class of chronic venous disease will be assessed for the study participants according to the CEAP classification, the severity of chronic venous disease will be evaluated using the VCSS scale, quality of life will be measured using the CIVIQ-20 questionnaire, and the intensity of venous-specific symptoms will be assessed using a numerical rating scale. After the surgical intervention, a class 1 compression stocking will be put on, which they will wear continuously for 24 hours; thereafter, it must be worn during the daytime for 28 days. Upon discharge, patients will receive a diary in which they will record postoperative pain and the fact of wearing the compression garment each day for 14 days. Follow-up visits will be scheduled for 14 days and 28 days after the surgical intervention.
