A saphena varix, or saphenous varix, is a dilation of the great saphenous vein at its junction with the femoral vein in the groin.
It is a common surgical problem, and patients may present with groin swelling.
It displays a cough impulse and may be mistaken for a femoral hernia.
[1] Saphena varix can be easily diagnosed by ultrasound.
Saphena varix shows flow on duplex ultrasonography.
