Prolonged Compression Following Foam Sclerotherapy

Foam-form sclerotherapy is an effective method for eliminating varicose veins, which can be used alone or in combination with other interventions (laser or radiofrequency ablation, cyanoacrylate glue embolization) in the treatment of chronic venous disease of the lower limbs. Sclerotherapy is utilized to address both primary and recurrent varicose veins, and it is associated with a low rate of complications. Among the adverse effects, the most common is skin hyperpigmentation (darkening of the skin with the formation of stripes of shades of brown directly above the treated veins), with an occurrence rate reaching 6-53% within the first month following the procedure. Still, it resolves independently in 70% of cases within 6 months. An essential component of sclerotherapy is compression therapy through bandages or medical stockings, which helps accelerate the absorption of veins and improve the aesthetic results of treatment. Meanwhile, the optimal duration for wearing compression stockings after performing foam-form sclerotherapy of varicose tributaries has not been established.
