Clinical Trial Summary

The study is aimed at assessing the dynamics of changes in biochemical markers of venous wall remodeling (type 1 plasminogen activation inhibitor (PAI-1), fibronectin (fibronectin, FN), vimentin (vimentin, VM), von Willebrand factor (vWF), PECAM-1 (CD31) ) in patients with C2s-C3s varicose veins compared with healthy volunteers while taking Venarus® (diosmin in combination with hesperidin).

Description:

The study will include 80 patients with varicose veins of the lower extremities, CEAP (CEAP classification stands for Clinical (C), Etiological (E), Anatomical (A), and Pathophysiological (P)) clinical class C2s-C3s and 20 healthy volunteers of similar age, gender, and ethnicity (100 patients altogether). The study participants will be divided into five groups: Group A: 20 patients with varicose veins who will be treated conservatively - receive the drug "Venarus®" (diosmin in combination with hesperidin) at a dosage of 1000 mg once daily for 6 months; Group B: 20 patients with varicose veins C2s-C3s who are not prescribed conservative therapy with venoactive drugs and will not undergo invasive treatment; Group C: 20 patients with varicose veins who will undergo invasive treatment (endovenous laser ablation with miniphlebectomy), followed by Venarus at a dosage of 1000 mg once daily for 6 months; Group D: 20 patients with varicose veins who will undergo invasive treatment (endovenous laser ablation with miniphlebectomy), after which no venoactive drugs will be prescribed. Group E: 20 healthy volunteers without clinical and ultrasound signs of varicose veins. All subjects in groups A, B, C, and D will receive elastic compression.
