Inferior epigastric artery
Inferior Epigastric Artery
The Inferior Epigastric Artery (IPA: /ɪnˈfɪər.i.ər ˌɛpɪˈɡæstrɪk ˈɑːrtəri/), from the Latin inferior meaning "lower" and epigastric referring to the area above the stomach, is a significant blood vessel in the human anatomy.
Anatomy
The Inferior Epigastric Artery originates from the external iliac artery, just above the inguinal ligament. It ascends obliquely upward, in the posterior wall of the inguinal canal, contained within the transversalis fascia, and behind the rectus abdominis muscle, to a point midway between the umbilicus and the pubis, where it anastomoses with the superior epigastric artery.
Function
The primary function of the Inferior Epigastric Artery is to supply blood to the lower part of the anterior abdominal wall and some of the pelvic organs. It also plays a crucial role in several surgical procedures, such as abdominal wall reconstruction and free flap breast reconstruction.
Clinical Significance
The Inferior Epigastric Artery is of clinical importance in several surgical procedures. It is often used as a landmark in laparoscopic surgery to avoid vascular injury. In addition, it is a common site of injury during hernia repair.
