Blood supply to the anterior abdominal wall


  • Inferior epigastric : External iliac
  • Superficial circumflex iliac : Femoral arterty
  • Deep circumflex iliac : femoral artery
  • Superior epigastric : internal thoracic
  • Lower intercostal :  Abdominal Aorta
  • Subcostal arteries : Abdominal aorta


The veins correspond to the arteries, but:

  • Inferior epigastric vein anastomoses with lateral thoracic vein.
  • Superficial epigastric vein anastomoses with lateral thoracic vein.

These two unite the veins of the upper and lower halves of the body (of the azygous system).
