- Gender predisposition: Female by 3 to 1 ratio
- Femoral seen less than Inguinal Hernia even in women
- Pathophysiology
- Associated with increased intra-abdominal pressure
- Hernia sac bulges into femoral canal
- Femoral canal is continuation of femoral sheath
- Femoral canal lies immediately medial to femoral vein
- Symptoms and Signs
- Groin Pain and tenderness often absent
- Even strangulation occurs often without pain
- Hernia sac neck location palpable
- Lateral and inferior to pubic tubercle
- Large femoral hernias may bulge over inguinal ligament
- May be difficult to distinguish from Inguinal Hernia
- Differential Diagnosis
- Inguinal Hernia
- Inguinal Lymphadenopathy
- Varix of Saphenous Vein
- Thrill on palpation
- Fills on standing and empties while supine
- Infectious Bubo
- Chancroid
- Syphilis
- Lymphogranuloma venereum
