Objective:
The purpose of this study was to determine the prevalence of femoral vein duplication and the incidence of bilateral anomalies in a normal cohort of patients presenting with varicose veins.
Methods:
Two hundred and forty patients underwent bilateral lower limb deep venous ultrasound examination with particular attention to the femoropopliteal segment.
Results:
The incidence of femoral vein duplication was 41%. Of the 140 people with femoral vein duplications, 60 (42%) were bilateral and 80 (57%) were unilateral.
Conclusion:
Femoral vein duplication is a common anatomical variant of the lower limb deep venous system. Ultrasound in skilled and experienced hands with the latest ultrasound units can readily demonstrate this venous anomaly on a consistent basis.
