Femoral Vein Anatomy

Femoral Vein Anatomy

  • 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
