Abdominal Aorta The abdominal Aorta supplies oxygenated blood to the abdominal organs and other visceral structures through its branches Position It starts posterior to the arcuate ligament at the T12 level from the descending (thoracic) Aorta It ends to the left of the mid-line at the L4 level and branches to become the common iliac arteries Topographical Relations Anterior Celiac trunk, branches and plexus Lesser sac Superior mesenteric, inferior mesenteric and left renal artery Pancreas Duodenum (ascending part) Attachment of mesentery Posterior Lumbar arteries Left lumbar vein Vertebral bodies Right Cisterna chyli Thoracic duct Azygos vein Right crus of diaphragm Inferior Vena Cava Left Left crus of diaphragm Duodenojejunal flexure Sympathetic trunk Inferior mesenteric vessels Parietal Branches Inferior phrenic artery → phrenic and supra-renal branch Renal artery → ureteric and supra-renal branch → apical, upper, middle, lower and posterior branches Gonadal artery Lumbar arteries Spinal arteries Common iliac artery Visceral Branches Renal artery Common iliac artery Medial sacral artery Celiac trunk:- Left gastric artery → esophageal branch Splenic artery → short gastric branch, splenic branch and left gastroepiploic artery Common hepatic artery → gastro-duodenal and proper hepatic artery Superior mesenteric artery:- Jejunal branch Ileal branch Iliocolic artery → appendicular, cecal and ascending colic artery Right colic artery Middle colic artery Inferior pancreatico-duodenal (anterior and posterior) artery Inferior mesenteric artery:- Left colic artery Sigmoid artery Superior rectal artery Links Bibliography SNELL, Richard S.
