Venous drainage from the laminar corium is via '''parietal veins''' from the laminar circulation to the '''parietal venous plexus''' and '''coronary venous plexus'''. The coronary venous plexus also receives veins from the perioplic and coronary corium. Veins from the solar and cuneate corium drain into the '''solar venous plexus'''.
Veins in the solar canal anastamose at the level of the distal sesamoid (navicular) bone, forming the '''medial and lateral terminal veins'''. The medial and lateral terminal veins join branches of the inner venous plexus to form the '''digital vein'''. This digital vein receives venous drainage from the navicular bone, coronary vein (coronary region), inner venous plexus and bulbar vein (heel).
Most of the venous drainage from the equine foot is via veins on the palmar aspect, which generally lack valves. Some small branches of the coronary, subcoronary and bulbar veins have valves. This means that bloodflow from the foot can take different routes and that weightbearing is essential for blood to flow proximally.
