In human anatomy of the leg, 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.

Anatomy

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.

Physiological significance

The position of the femoral canal medially to the femoral vein is of physiologic importance. The space of the canal allows for the expansion of the femoral vein when venous return from the lower limbs is increased or when increased intra-abdominal pressure (valsalva maneuver) causes a temporary stasis in the venous flow.

Femoral canal
	Femoral sheath laid open to show its three compartments. (The femoral canal is both visible and labeled [difficult to see label] medial to the femoral vein.)
	Structures passing behind the inguinal ligament. The entrance to the femoral canal, the femoral ring, is labeled at right.
