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.

[edit] Drainage
Several large veins drain into the femoral vein:
[edit] Clinical significance
Occlusion of the femoral vein can be life-threatening.[1]
The practice of delivering drugs intraveinously using the femoral vein is common amongst IDUs.[2]
[edit] Use of the term superficial femoral vein
The term superficial femoral vein is not recognized as a legitimate anatomic term.[3]
However, some specialist physicians (e.g. radiologists, vascular surgeons) use the term superficial femoral vein for the distal part of the femoral vein to:
- differentiate the femoral vein segments before and after the profunda femoris vein joins with it, and
- differentiate the distal segment of the femoral vein from the deep femoral vein (profunda femoris vein), which is paired with the profunda femoris artery.
Usage of this term is discouraged by many physicians because it leads to confusion among general medical practitioners.[1]
The femoral vein is considered a deep vein, unlike the adjective superficial suggests and has lead some physicians to falsely conclude it is a superficial vein, which has resulted in patients (with deep vein thrombosis) being denied efficacious thrombolytic therapy.[3]
