What is a duplicated popliteal vein?

Abstract. Background: Duplication of the popliteal and superficial femoral veins (PV, SFV) is a normal variant previously reported in up to 25% of limbs. Little clinical significance, however, has been attributed to this apparently common anomaly.

Can you have two popliteal veins?

Although the presence of true duplication of the popliteal vein described above is quite rare, a high origin of the popliteal vein from two or more tributaries is much more common. In our material this anatomical variant was present in almost 19% of studied lower limbs.

What does popliteal vein divide into?

The popliteal vein then ascends and passes through the adductor hiatus (an opening formed between the two insertions of the adductor magnus muscle) to become the femoral vein, which passes superiorly and runs in the femoral triangle medial to the femoral artery, which is itself medial to the femoral nerve.

What two veins form the popliteal vein?

The popliteal vein forms from the posterior and anterior tibial veins and ascends through the popliteal fossa to the opening in adductor magnus alongside the popliteal artery where it becomes the femoral vein.

What is duplicated femoral vein?

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.

Where is the Saphenofemoral junction located?

groin
The sapheno-femoral junction (SFJ) is located at the saphenous opening within the groin and formed by the meeting of the great saphenous vein (GSV), common femoral vein and the superficial inguinal veins (confluens venosus subinguinalis).

How many popliteal veins are there?

Blood flows into the popliteal vein from multiple tributaries in the lower leg, including the:3. The popliteal vein itself originates where the anterior and posterior tibial veins join together, at the back of the knee. From there, the popliteal vein runs through the popliteal fossa.

Can you get a DVT behind the knee?

Popliteal vein thrombosis happens when a blood clot blocks one of the blood vessels behind your knees. It’s a serious condition, but it can sometimes be mistaken for a less-dangerous condition called a Baker’s cyst.

What are the branches of the popliteal vein?

The tributaries of the popliteal vein include:

  • Veins that correspond to branches given off by the popliteal artery (see popliteal artery).
  • the small saphenous vein, which perforates the deep fascia and passes between the two heads of the gastrocnemius muscle to end in the popliteal vein.
  • the fibular veins.

Where is the popliteal vein located?

The popliteal vein is found within the popliteal fossa. The popliteal fossa is defined by the biceps femoris proximolaterally; the semimembranosus and semitendinosus muscles proximomedially; and gastrocnemius distally. The tibial nerve, popliteal vein, and popliteal artery are all found within the fossa.

What is the common femoral vein?

The common femoral vein (CFV) forms from the confluence of the femoral vein and the deep femoral vein, and continues as the external iliac vein at the inguinal ligament. It accompanies the common femoral artery.
