Chronic venous insufficiency (CVI) is a medical condition characterized by blood pooling in the veins, leading to increased pressure and strain on the vein walls. [1] The most common cause of CVI is superficial venous reflux, which often results in the formation of varicose veins, a treatable condition. [2]

Symptoms classically affect a leg and typically develop over hours or days, [20] though they can develop suddenly or over a matter of weeks.
