The deep femoral artery is a large and important branch that arises from the lateral side of the femoral artery about 1.5 in. (4 cm) below the inguinal ligament. It passes medially behind the femoral vessels and enters the medial fascial compartment of the thigh .
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 mid-inguinal point, halfway between the anterior superior iliac spine and the pubic symphysis, is the landmark for the femoral artery.
It passes down along the brim of the pelvis and gives off two large branches - the "inferior epigastric artery" and a "deep circumflex artery." These vessels supply blood to the muscles and skin in the lower abdominal wall. The external iliac artery passes beneath the inguinal ligament in the lower part of the abdomen and becomes the femoral ...
The superficial inguinal ring (subcutaneous inguinal ring or external inguinal ring) is an anatomical structure in the anterior wall of the mammalian abdomen. It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve , the genital branch of the genitofemoral nerve , and the spermatic cord (in men ...
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.
The common femoral vein is the segment of the femoral vein between the branching point of the deep femoral vein and the inferior margin of the inguinal ligament. [ 5 ] [ 6 ] It is not listed in Terminologia Anatomica , which is the international standard for human anatomical terminology developed by the Federative International Programme on ...
After piercing the femoral sheath and fascia cribrosa, it courses medialward, across the spermatic cord (or round ligament in the female), to be distributed to the integument on the lower part of the abdomen, the scrotum in the male, and the labium majus in the female, anastomosing with branches of the internal pudendal artery.
The hernial sac emerges from the abdomen within the femoral sheath but lies posteriorly to the femoral vein and artery, visible only if the hip is congenitally dislocated. 'Serafini's hernia' The hernial sac emerges behind femoral vessels (E). 'Velpeau hernia' The hernial sac lies in front of the femoral blood vessels in the groin (B).
