The femoral vein continues into the thigh as the continuation from the popliteal vein at the back of the knee. It drains blood from the deep thigh muscles and thigh bone. [2] Proximal to the confluence with the deep femoral vein, and the joining of the great saphenous vein, the femoral vein is widely known as the common femoral vein. [3]
The deep femoral vein, deep vein of the thigh or profunda femoris vein is a large deep vein in the thigh. It collects blood from the inner thigh, passing superiorly and medially alongside the deep femoral artery before emptying into the femoral vein .
A continuation of the femoral vein, [1] the external iliac vein starts at the level of the inguinal ligament. [2] It runs beside its corresponding artery and along the brim of the lesser pelvis to unite with the internal iliac vein anterior to the sacroiliac joint where it forms the common iliac vein.
Femoral vein and its tributaries - The vein lies medial to the femoral artery at the base of the triangle but as it approaches the apex of the triangle, it lies posteromedially to the femoral artery. It receives drainage from great saphenous vein, circumflex veins, and veins corresponding to the branches of the femoral artery here. [2]
Veins are a draining system similar to a low pressure hydraulic system, with a laminar flow and a low velocity. This low velocity is responsible for the fact that it can only be detected spontaneously with the Doppler effect on the proximal and larger femoral and iliac veins. Here the flow is either modulated by the respiratory rhythm or is ...
The deep veins of the lower limb include the common femoral vein, femoral vein, and the deep femoral vein; the popliteal vein, the tibial, and fibular veins. In the common femoral vein one valve is located above the saphenofemoral junction called the suprasaphenic valve. There are sometimes two valves in the same tract. In the femoral vein ...
The function of the femoral canal is to accommodate the distension of the femoral vein when venous return from the leg is increased or temporarily restricted (e.g. during a Valsalva maneuver). [1] The proximal, abdominal end of the femoral canal forms the femoral ring. [1] The femoral canal should not be confused with the nearby adductor canal.
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).
