In the human body, the femoral vein is a blood vessel that accompanies the femoral artery in the femoral sheath. It begins at the adductor canal (also known as Hunter's canal) and is a continuation of the popliteal vein. It ends at the inferior margin of the inguinal ligament, where it becomes the external iliac vein.
Several large veins drain into the femoral vein:
Occlusion of the femoral vein can be life-threatening.
Use of the term superficial femoral vein
The term superficial femoral vein is recognized as a legitimate anatomic term.
- differentiate the femoral vein segments before and after the deep vein of the thigh (profunda femoris vein) joins with it, and
- differentiate the distal segment of the femoral vein from the deep vein of the thigh, which is paired with the deep artery of the thigh.
The femoral vein is considered a deep vein, unlike the adjective superficial suggests and has led some physicians to falsely conclude it is a superficial vein, which has resulted in patients (with deep vein thrombosis) being denied efficacious anticoagulant or thrombolytic therapy.
