Femoral Sheath And Femoral Canal | Contents | Boundaries | Relations 

the femoral sheath has three compartments. The lateral compartment contains the femoral artery, the intermediate compartment contains the femoral vein, and the medial and smallest compartment is called the femoral canal. The femoral canal contains efferent lymphatic vessels and a lymph node embedded in a small amount of areolar tissue. It is conical in shape and is about 2 cm long.
The femoral canal is bordered:
anterosuperiorly by the inguinal ligament
posteriorly by the pectineal ligament lying anterior to the superior pubic ramus
Medially by the lacunar ligament
Laterally by the femoral vein
It contains the lymph node of Cloquet. It should not be confused with the nearby adductor canal.
Clinical significance
The entrance to the femoral canal is the femoral ring, through which bowel can sometimes enter, causing a femoral hernia. Though femoral hernias are rare, their passage through the inflexible femoral ring puts them at particular risk of strangulation, giving them surgical priority.
