Inguinal hernia a result, the possibility for hernias through the inguinal canal in males is much greater because they have a larger opening and therefore a much weaker wall through which the intestines may protrude. Inguinal hernias, in turn, belong to groin hernias, which also includes femoral hernias. A femoral hernia is not via the inguinal canal, but via the femoral canal, which normally allows passage of the common femoral artery and vein from the pelvis to the leg. In Amyand's hernia, the content of the hernial sac is the vermiform appendix. In Littre's hernia, the content of the hernial sac contains
Superficial circumflex iliac artery Superficial circumflex iliac artery The superficial iliac circumflex artery (or superficial circumflex iliac), the smallest of the cutaneous branches of the external iliac artery, arises close to the superficial epigastric artery, and, piercing the fascia lata, runs lateralward, parallel with the inguinal ligament, as far as the crest of the ilium. It divides into branches which supply the integument of the groin, the superficial fascia, and the superficial subinguinal lymph glands, anastomosing with the deep iliac circumflex, the superior gluteal and lateral femoral circumflex arteries. In 45% to 50% of persons the superficial circumflex iliac artery and superficial inferior epigastric
