Chronic venous insufficiency (CVI) occurs when veins in the legs fail to efficiently return blood to the heart, leading to symptoms like leg swelling, varicose veins, and skin changes. All recommendations are sourced from the American Society for Vascular Surgery and the American Venous Forum:
First-line recommendations:
Compression therapy: Wear graduated compression stockings with 20-30 mmHg compressive pressure at least up to thighs to improve venous return. Should be worn long-term all day, every day. Elasticity is lost over time; use two pairs that should be alternated daily and replace after 6–9 months. Popular Unisex Compression Stockings
Lifestyle modifications: Elevate legs several times a day and avoid prolonged standing or sitting. Engage in regular exercise to promote circulation. Electric Seated Pedal Exercise Tool.
Supplement recommendations:
Horse chestnut seed extract (aescin) was found in 17 randomized controlled trials to be effective in decreasing edema, pain, and itching. Chestnut extract 300 mg tablets.
Prescription medications and intervention:
Aspirin or pentoxifylline: May be prescribed to reduce inflammation and improve blood flow in severe cases.
Sclerotherapy: Injection of a sclerosant into varicose veins to close them.
Endovenous laser therapy (EVLT) or radiofrequency ablation (RFA): Minimally invasive procedures to treat refluxing veins.
Surgical interventions: For advanced cases, vein stripping or ligation may be performed.
