Normal vs Abnormal Venous Valve

Normal Vs Abnormal venous valve

Venous valves are bicuspid valves that allow venous blood to flow in one direction only (cephalad). As shown in both video, the venous valve presents an enlargement called valve sinus where the valve leaflets are in normal circumstances mobile and prevent venous reflux (continent valve). The lumen of a normal and patent vein often appears anechoic in absence of venous stasis as shown in the first part of the video. The second part of the videos shows a malfunctioning great saphenous vein pre-terminal valve with reduced mobility of the valve leaflets, spontaneous echo contrast noted within the lumen due to venous stasis.
