saphenous vein
Pronunciation: sah-FEE-nus
Superficial leg vein system including great and small saphenous veins, commonly affected by venous insufficiency.
Full Definition
The saphenous vein system consists of the great saphenous vein (GSV) and small saphenous vein (SSV), which are the two main superficial venous channels of the lower extremity. The GSV runs from the dorsal foot to the saphenofemoral junction in the groin, while the SSV extends from the lateral foot to the popliteal fossa. These veins are frequently involved in venous insufficiency and varicose vein formation. They also serve as important conduits for arterial bypass procedures when harvested as autologous grafts.
Usage
Usage note: Specify 'great' or 'small' saphenous vein for anatomical precision.
