Bilateral femoral hernia in a male cadaver with vascular variations: case report and review of the literature.

Femoral hernia, which is a less common occurrence than inguinal hernia, is not congenital in most cases and is uncommon in young males. It is considered to be more common in females than in males due to an enlarged femoral ring in the former. A case of bilateral femoral hernia in a 64-year-old male cadaver is described within the framework of an anatomical approach. On the right side, the protrusion of the viscus appeared as a small intestine coil, whereas on the left side the protruded viscus appeared as a pelvic colon's appendix appiplocae. On both sides, the protruded viscus was located in front of an aberrant obturator artery, which oriented from the external iliac artery and not from the internal iliac artery as should be the case. The puberal branch of the inferior epigastric artery was absent. The cadaver's medical history and his skin examination excluded an abdominal surgery. In the literature, case reports of bilateral femoral hernia appear only seldom, especially those of male patients who had not undergone inguinal hernia repair surgery. In femoral hernias more often than in other types of hernia, the protruded viscus is strangulated and undergoes a tissue necrosis. Morbidity and mortality for complicated femoral hernia is high. Knowledge of vascular variation such as presented by the cadaver under study is extremely useful to the surgeon because any iatrogenic injury of the aberrant obturator artery during a laparoscopic repair may result in dangerous hemorrhage.
