The blood vessels of the anterior abdominal wall are derived from five sources. The arteries concerned are (1) the Superior Epigastric and Musculophrenic branches of the internal thoracic artery; (2) the lower two Posterior Intercostal arteries, the Subcostal artery, and the four Lumbar arteries from the aorta; (3) the Superficial Epigastric, Superficial Circumflex Iliac, and Superficial External Pudendal branches of the femoral artery; (4) the Inferior Epigastric and Deep Circumflex Iliac branches of the external iliac artery; and (5) the Iliolumbar branch of the internal iliac artery. Certain terminal branches of these five sources contribute to anastomoses.
