The degree of reduction of the diameter of the great saphenous vein in the postoperative period in patients operated by thermal techniques

Annotation. The article presents the results of a study aimed at assessing changes in the diameter of the great saphenous vein of the lower extremities in patients with varicose veins treated with thermal methods. Two thermal techniques were considered in the study, namely endovenous laser ablation and radiofrequency ablation. The changes in the diameter of the great saphenous vein at different stages of treatment were compared: before surgery, 2 weeks, 1 month, 3 months, 6 months and 12 months after the intervention. The ultrasound method was used to determine the change in the diameter of the great saphenous vein. The results were processed using Microsoft Office for Windows software. The statistical analysis showed that both methods demonstrate high efficiency in the treatment of patients with varicose veins of the lower extremities. In both groups, a significant reduction in vein diameter was observed at each of the control stages. The conclusions of the study are of practical importance for choosing the optimal treatment tactics for patients with varicose veins of the lower extremities. They can serve as a basis for further clinical trials aimed at improving thermal techniques and evaluating their effectiveness in different groups of patients.
