This allows blood to pool in the lower extremities, leading to swelling and other symptoms. CVI is particularly common among older adults and can range from mild to severe, with untreated cases sometimes resulting in serious complications ( 2 , 4 , 6 ). Understanding Chronic Venous Insufficiency Chronic venous insufficiency develops when the valves in the leg veins weaken or are damaged, disrupting normal blood flow back to the heart. The malfunctioning valves cause blood to flow backward (venous reflux) and collect in the legs, increasing venous pressure ( 1 , 3 , 5 ).
