The clinical anatomy of the inferior abdominal wall artery is located posterior to the combined tendons of the internal and external oblique abdominal muscles. The inferior abdominal wall artery has several branch arteries that nourish the tissues of the distribution area, the most important branches being the pubococcygeal branch artery and the levator ani artery. The inferior abdominal wall artery is slightly medial to the midpoint of the inguinal ligament and originates from the external iliac artery, which runs along the medial side of the internal inguinal canal ring and travels obliquely upward within the tendinous tissue of the external oblique abdominal muscle, penetrating the transverse abdominal fascia and ascending between the rectus abdominis muscle and the posterior layer of the rectus abdominis sheath. After incision of the tendon membrane of the external oblique muscle, the tendon membrane of the internal oblique muscle and the joint tendon, the inferior abdominal wall artery can be revealed. Therefore, in surgical inguinal surgery, the inferior abdominal wall artery is used as a marker to distinguish inguinal hernias from straight inguinal hernias. If the inferior abdominal wall artery is damaged, the main manifestation is bleeding of varying degrees, which can occur as intra-abdominal hemorrhage, extensive bruising and bruising within the skin. The abnormality should be detected and treated accordingly at the hospital, such as ligation treatment.
