|Superficial Femoral Vein (SFV)||Femoral Vein||The incorrect term can lead to confusion, especially in the context of deep vein thrombosis.|
Understanding the Misnomer
The term “Superficial Femoral Vein” or “SFV” is commonly used by radiologists and ultrasound technologists. However, this term is considered a misnomer.
Why is it a Misnomer?
The term “superficial femoral vein” suggests that this vein is superficial or close to the surface of the body. However, this is not the case. The SFV is actually located deep within the thigh, making it part of the deep venous system.
Table 1: Comparison of Superficial and Deep Veins
|Superficial Veins||Deep Veins|
|Close to the surface of the body||Located deep within the body|
|Generally do not accompany arteries||Generally accompany arteries|
|Examples: Great saphenous vein, small saphenous vein||Examples: Femoral vein, popliteal vein|
The Confusion with Deep Vein Thrombosis
Deep Vein Thrombosis (DVT) is a serious condition where a blood clot forms in one of the body’s deep veins. Since the SFV is part of the deep venous system, a clot in this vein would be classified as DVT. However, if a healthcare professional misunderstands the SFV as a superficial vein due to its name, they might underestimate the severity of a clot in this vein.
The Correct Terminology and Its Impact
According to the Terminologia Anatomica, the international standard for anatomical terminology, the correct term for the SFV is simply “femoral vein”.
Anatomy and Course of the Femoral Vein
The femoral vein runs alongside the femoral artery in the upper thigh. It plays a crucial role in returning blood from the lower half of the body back to the heart.

|Behind the knee (becomes popliteal vein)||Popliteal artery|
Implications of Using Incorrect Terminology
Using incorrect terminology can lead to confusion and potential misdiagnosis. For example, a healthcare professional might underestimate the severity of a clot in the SFV if they misunderstand it as a superficial vein.
It’s important for radiologists and ultrasound technologists to use correct terminology. This not only ensures clear communication but also helps prevent potential misdiagnoses. By understanding why “superficial femoral vein” is a misnomer and using the correct term “femoral vein”, we can improve patient care and outcomes.
