title: The role of circumflex femoral veins in the saphenofemoral junction incompetence: a case report.
abstract: A 31 year-old female patient, an opera singer, came for a consultation, mainly for aesthetic problems of the lower limbs. An asymptomatic bilateral P-point pelvic shunt was demonstrated by the EchoDoppler, while no nutcracker syndrome was detected. The examination demonstrated a medial circumflex femoral vein (MCFV), going into the common femoral vein and then into the great saphenous vein (GSV). The Valsalva manoeuvre showed the GSV terminal valve incompetence. A dilated MCFV vein at the level of the saphenofemoral junction was the source of the reflux through the GSV, while the external iliac vein was competent. GSV reflux with Valsalva was present only in the lying position. Flow in the MCFV was directed toward the CFV during and after the Valsalva. The examination shows clearly that a GSV reflux can sometimes occur in absence of iliac reflux. Circumflex femoral veins (medial and lateral) are anatomical variations, but common findings during ordinary EchoColourDoppler investigations of the venous system of the lower limbs.
