Femoral sheath
FEMORAL SHEATH
- Femoral sheath is a funnel shaped fascial prolongation around proximal part of femoral vessels, situated in the femoral triangle, below the inguinal ligament.
- It is 3-4 cm long.
- Distance between femoral ring and saphenous opening is 1.25cm
- It is formed by fascia iliaca.
COMPARTMENTS:
- Femoral sheath is divided into 3 separate fascial compartements by septa :
- Lateral compartment :- It contains femoral artery and femoral branch of genitofemoral nerve.
- Intermediate compartment :- Femoral vein.
- Medial compartment (femoral canal) :
- It is conical in shape, wider above and narrow below.
- Femoral artery lies outside the femoral sheath
- The wider upper opening is known as femoral ring, which is potentially a weak point in lower abdomen and is the site for femoral hernia.
Femoral ring is bounded :
- Anteriorly by inguinal ligament,
- medially by lacunar ligament,
- posteriorly by pectineus with its covering fascia, and
- laterally by septum separating it from femoral vein.
- Femoral canal contains lymph node of cloquet or Rosenmuller and lymphatics.
