Femoral Vein Anatomy 6/8/10 SP Notes - continuation of the popliteal vein lies in the intermediate compartment of the femoral sheath accompanies the femoral artery in the femoral triangle at the inguinal ligament it becomes the external iliac vein FEMORAL TRIANGLE - superior: inguinal ligament medial border: adductor longus lateral border: sartorius apex: sartorius crossing the adductor longus muscle roof: skin subcutaneous tissue, the cribriform fascia and the fascia lata floor: adductor longus, adductor brevis, pectineus and iliopsoas muscles LANDMARKS - anterior superior iliac spine (ASIS) pubic ramus inguinal ligament femoral sheath medially -> laterally (vein, artery, nerve) INSERTION POINT - 1cm below inguinal ligament - 1cm medial to femoral arterial pulsation STRUCTURES NEEDLE PASSES THROUGH (superficial -> deep) - skin - subcutaneous tissue - fascia (encloses the femoral vessels) - femoral vein - medial: medial compartment of femoral sheath (femoral canal – lymph vessels, nodes and fatty tissue) - lateral: fibrous septum separating intermediate compartment and lateral compartment (containing femoral artery) and further lateral = femoral nerve - posterior: posterior fascia and pectineus Jeremy Fernando (2011) Jeremy Fernando (2011)
