Anterior femoral cutaneous vein
The anterior femoral cutaneous vein, also known as the anterolateral vein of the thigh, drains an area of its anterior superficial aspect. It is located specifically at the thigh's distal aspect and travels upward, where it accesses the femoral vein before that vein travels into the saphenous opening. The anterior femoral cutaneous vein has two branches: the intermediate cutaneous nerve and the medial cutaneous nerve. The intermediate cutaneous nerve branch of the anterior femoral cutaneous vein enters the fascia lata approximately 7.5 centimeters below the inguinal ligament, where it splits into two branches. These branches descend along the thigh's forepart and supply the skin down to the front of the knee. The medial cutaneous nerve branch of the anterior femoral cutaneous vein travels under the femoral artery's upper sheath and supplies the thigh's medial side. It divides at that vessel's medial side into two branches: the anterior branch and the posterior branch. These both communicate with the saphenous nerve inside the fascia lata and divide into various cutaneous branches, after which they travels down to supply the integument located on the leg's medial side.
