It is bounded by the inguinal ligament anteriorly, pectineal ligament posteriorly, lacunar ligament medially, and the femoral vein laterally. It normally contains a few lymphatics, loose areolar tissue, and occasionally a lymph node called Cloquets node. The function of this canal appears to be to allow the femoral vein to expand when necessary to accommodate increased venous return from the leg during periods of activity. Diagnosis
The diagnosis is largely a clinical one, generally done by physical examination of the groin. However, in obese patients, imaging in the form of ultrasound, CT, or MRI may aid in the diagnosis. For example, an abdominal X-ray showing small bowel obstruction in a female patient with a painful groin lump needs no further investigation. Several other conditions have a similar presentation and must be considered when forming the diagnosis: inguinal hernia, an enlarged femoral lymph node, aneurysm of the femoral artery, dilation of the saphenous vein, athletic pubalgia, and an abscess of the psoas. Classification
Several subtypes of femoral hernia have been described. Management
Femoral hernias, like most other hernias, usually need operative intervention. This should ideally be done as an elective (non-emergency) procedure. However, because of the high incidence of complications, femoral hernias often need emergency surgery. Surgery
Some surgeons choose to perform "key-hole" or laparoscopic surgery (also called minimally invasive surgery) rather than conventional "open" surgery.
Such constant pressure causes preperitoneal fat to insinuate in the femoral ring, a consequence of which is development of a femoral peritoneal sac. References
