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.
When the obturator artery travels along the lacunar ligament, it nearly encircles the femoral ring and can be lacerated during a femoral hernia repair. Most femoral hernias are repaired through a small (1/2 to 3/4 inch) incision in the groin area, rather than through the abdomen, so if a laceration were to occur, bleeding may not be immediately ...
De Garengeot's hernia is a rare subtype of an incarcerated femoral hernia. This eponym may be used to describe the incarceration of the vermiform appendix within a femoral hernia . [ 1 ] This mechanism is contrasted with the Amyand hernia, in which the appendix protrudes through an inguinal hernia.
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.
An obturator hernia is a type of hernia involving an intrusion into the obturator canal. The obturator nerve can be compressed in the obturator canal. [2] The obturator canal may be compressed during pregnancy and major traumatic injuries, causing obturator syndrome. [3]
This structure demarcates the superior border of the femoral triangle. [4] It demarcates the inferior border of the inguinal triangle. The midpoint of the inguinal ligament, halfway between the anterior superior iliac spine and pubic tubercle, is the landmark for the femoral nerve.
The lacunar ligament is the only boundary of the femoral canal that can be cut during surgery to release a femoral hernia. Care must be taken when doing so as up to 25% of people have an aberrant obturator artery (corona mortis) which can cause significant bleeding. [4]
[12] Obturator hernias occur more frequently on the right side compared to the left side because the sigmoid colon physically blocks the left obturator foramen, preventing the formation of the hernia. The formation of an obturator hernia occurs in three stages: the prehernial stage, the developmental stage, and the third stage. [13]
