A strangulated femoral hernia occurs when a constriction of the hernia limits or completely obstructs blood supply to part of the bowel involved in the hernia. Strangulation can occur in all hernias, but is more common in femoral and inguinal hernias due to their narrow "weaknesses" in the abdominal wall.
A femoral hernia develops when inner tissue protrudes from a hole in the thigh called the femoral canal. Folks with femoral hernias often have severe pain and a noticeable bulge.
The incidence of strangulation in femoral hernias is high. Repair techniques are similar for femoral and inguinal hernia. A Cooper's hernia is a femoral hernia with two sacs, the first being in the femoral canal, and the second passing through a defect in the superficial fascia and appearing almost immediately beneath the skin.
The entrance to the femoral canal is the femoral ring, through which bowel can sometimes enter, causing a femoral hernia.Though femoral hernias are rare, their passage through the inflexible femoral ring puts them at particular risk of strangulation, giving them surgical priority.
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 appendix.
Inguinal hernia surgery is an operation to repair a weakness in the abdominal wall that abnormally allows abdominal contents to slip into a narrow tube called the inguinal canal in the groin region. There are two different clusters of hernia: groin and ventral (abdominal) wall. Groin hernia includes femoral, obturator, and inguinal. [1]
