Lower limb venous physiology and function
The 2 major veins of the superficial system namely the Great Saphenous and Short Saphenous (GSV and SSV).
Chronic Venous Insufficiency (CVI) and Varicose veins (VV)
Primary venous disease occurs as a result of focal or diffuse structural weakening of the vein wall. The exact nature and cause are not completely understood. Valvular incompetence in the superficial veins can occur due to disruption by thrombotic events, be congenitally absent, atretic or dysfunctional over time.
