Surgery Definition – What is the anatomy of the abdominal aorta?
Abdominal aorta spans form T12 which is behind the median arcuate ligament to L4 and at L4 it bifurcates into right and left common iliac arteries.
There are branches to the abdominal aorta which include unpaired branches such as coeliac trunk, superior mesenteric artery, inferior mesenteric artery, medical sacral artery, paired visceral branches such as suprarenal arteries, renal arteries and gonadal arteries and paired abdominal wall branches such as subcostal arteries, inferior phrenic arteries and lumbar arteries.
Coeliac trunk consists of branches that include hepatic artery, splenic artery and left gastric artery.
The right renal artery is longer compare to the left renal artery due to aorta being displaced slightly to the left.
