Blood Vessels of the Abdomen and Pelvis

Arterial Supply of the Abdomen

The Abdominal Aorta

 

Relations of the Abdominal Aorta

  1. The coeliac trunk and its branches;
  2. The coeliac plexus;
  3. The omental bursa;
  4. The pancreas;
  5. The left renal vein;
  6. The ascending part of the duodenum;
  7. The root of the mesentery;
  8. And the intermesenteric plexus of nerves.
  1. The bodies of L1 to L4 vertebrae;
  2. The intervening intervertebral discs;
  3. And the corresponding part of the anterior longitudinal ligament.
  1. The cisterna chyli;
  2. The thoracic duct;
  3. And the right crus of the diaphragm.

Ventral Branches

  1. Left gastric artery branches with the aortic oesophageal branches around the lower oesophagus.
  2. Anterior and posterior superior pancreaticoduodenal arteries (coeliac trunk) with the inferior pancreaticoduodenal (superior mesenteric branch) around the head of the pancreas and 2nd part of the duodenum.
  3. The marginal artery anastomosis between the middle colic and the left colic.
  4. The superior rectal artery (inferior mesenteric) with the middle rectal (internal iliac) and/or the inferior rectal (internal pudendal from internal iliac).
