Blood Vessels of the Anterior Abdominal Wall


Superior epigastric artery
  • Arises from the internal thoracic artery , enters the rectus sheath, and descends on the posterior surface the rectus abdominis.
  • Anastomoses with the inferior epigastric artery within the rectus abdominis
Inferior epigastric artery
  • Arises from the external iliac artery above the inguinal ligament, enters the rectus sheath, and ascends between the rectus abdominis and the posterior layer of the rectus sheath.
  • Anastomoses with the superior epigastric artery, providing collateral circulation between the subclavian and external iliac arteries.
  • Gives rise to the cremasteric artery , which accompanies the spermatic cord.
Deep circumflex iliac artery
  • Arises from the external iliac artery and runs laterally along the inguinal ligament and the iliac crest between the transverse and internal oblique muscles.
  • Forms an ascending branch that anastomoses with the musculophrenic artery.
Superficial epigastric arteries
  • Arise from the femoral artery and run superiorly toward the umbilicus over the inguinal ligament.
  • Anastomose with branches of the inferior epigastric artery.
Superficial circumflex iliac artery
  • Arises from the femoral artery and runs laterally upward, parallel to the inguinal ligament.
  • Anastomoses with the deep circumflex iliac and lateral femoral circumflex arteries.

Superficial (external) pudendal arteries
  • Arise from the femoral artery, pierce the cribriform fascia, and run medially to supply the skin above

Thoracoepigastric veins
  • Are longitudinal venous connections between the lateral thoracic vein and the superficial epigastric vein.
  • Provide a collateral route for venous return if a caval or portal obstruction occurs.
