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]
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).
Also, at the groin it can be seen at the outside of the great saphenous vein, and together with the common femoral vein (CFV) these three create an image, the so-called "Mickey Mouse sign". Some authors, inspired by this sign (presented for the first time at CHIVA's 2002 meeting in Berlin), described a "Mickey Mouse view" at the groin, an image ...
The femoral sheath is subdivided by two vertical partitions to form three compartments (medial, intermediate, and lateral); the medial compartment is known as the femoral canal and contains lymphatic vessels and a lymph node, whereas the intermediate canal and the lateral canal accommodate the femoral vein and the femoral artery (respectively ...
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.
