Femoral sheath

Anatomical structure of the upper thigh

The femoral sheath is a funnel-shaped downward extension of abdominal fascia within which the femoral artery and femoral vein pass between the abdomen and the thigh. The femoral sheath is subdivided by two vertical partitions to form three compartments ; 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). Some neurovascular structures perforate the femoral sheath. Topographically, the femoral sheath is contained within the femoral triangle.
