Blood vessels of the anterior abdominal wall

The superior and inferior epigastric arteries provide a rich arcade arising from the internal thoracic artery superiorly and the external iliac artery inferiorly. The musculophrenic artery, deep circumflex iliac artery, and subcostal arteries supply the lateral abdominal wall. The superficial epigastric veins and the superficial iliac veins can arise from the great saphenous vein.
