Abdominal aorta (Aorta abdominalis)
Educational content only — not medical advice.
Anatomy
Runs retroperitoneally from the diaphragm to L4 where it bifurcates into the common iliacs; it gives the coeliac trunk, superior and inferior mesenteric, renal, adrenal and lumbar arteries — the supply tree of every abdominal viscus.
Clinical notes
An aneurysm beyond 5.5 cm threatens rupture with pulsating abdominal-back pain, monitored yearly by ultrasound; progressive atherosclerosis can strip the renal ostia into renovascular hypertension.
