Depth of the femoral vein: anatomy and superficial formations

General characteristics The depth of the femoral veins consists of main and accessory branches originating in the perineal area. The plexus can be easily palpated, as it is located on the side of the vein at the level of the subcutaneous fissure. The deep femoral veins supply the lower limb and participate in the circulation of blood from the tissues, muscles, bones and joints of the lower limbs and the entire body. The vein is especially visible in those who lead a sedentary lifestyle. It includes not only the femoral veins, but also other formations. These include branches of the iliac, external and internal genital veins. They all originate from the greater and lesser iliac veins. The foliage of the femoral trunk travels along the fiber, entering the round and oval fiber. From the pelvis, vascular channels are distributed along the inner surfaces of the muscles

Deep femoral veins, lat. vǎnae profýndae fémorales, a widely used anatomical name for the large calf vein of humans and some other mammals. The deep veins of the thigh and leg are an important component of the venous system of the lower extremities, carrying out the outflow of venous blood from the popliteal, tibial, peroneal and lateral saphenous veins. They ensure the return of blood from all parts of the foot, hand, and forearm with the development of three main trunks on the upper border of the middle third of the thigh: the superficial tributary (transverse vein of the thigh), the deep tributary and the descending trunk, merging into one trunk. From the lower third along the outer surface of the thigh there are the origins of two more veins: the lateral edge of the large saphenous venule and the subcutaneous venule cava, which are small branches of the main trunk of the deep veins of the thigh. Each of these veins drains blood from the skin and muscles of the limbs listed above. Sometimes all four large components - the transverse and longitudinal femoral vein, the vein of the lateral and medial edges - form, as it were, one continuous deep venous trunk of the thigh 2-3 cm thick, known as the deep vein of the femur. An anatomical feature is the fact that blood from the small saphenous vein flows not only to the thigh muscles, but also to the surface layer of the skin; this explains the varicose changes in the latter. The longitudinal medial and medial plantar veins anastomose with each other, giving rise to one or more large and small tributary trunks, which, in turn, flow into the internal superior and anterior superior deep saphenous vein. In the supine position, the small and large venous trunks are laid along the corresponding limbs, two veins in each place. Three or four major veins form a vascular muff around the inside of the ankle, somewhat resembling a pillow. In women, on the front of the tibia lies the tendon of the long saphenous muscle (gastrocnemius), extending to the inner malleolus.
