== '''Coeliac artery''' ==

* Artery to the foregut,     supplying from the distal oesophagus to D2, liver, GB, spleen, pancreas
* Branches at T12, almost     perpendicular to the aorta, then courses anterolaterally in the lesser sac     for 12mm
* Most often forms a     trifurcation
** Hepatic artery - see 'liver'
*** Passes to the right beneath       the posterior peritoneum of the omental bursa, enters the hepatoduodenal       ligament and ascends to the hilum of the liver on the left side of the       CBD
** Splenic artery - see      'spleen'
*** Descends beneath the       peritoneum to undulate along the cephalad border of the pancreas, where       it gives off a dorsal pancreatic branch and others
** Left gastric artery - see      'stomach'
* Left gastric ('coronary     vein') crosses over the coeliac trunk in its course from the lesser curve     of the stomach to the portal vein
* Variations:
** Branching patterns
*** Bifurcation into       hepatosplenic and left gastric 50-75%
*** Trifurcation 10-20%
*** Quadrifurcation (GDA,       right/left hepatic, dorsal pancreatic)
** Any of the three main      branches may arise independently from the aorta/SMA (most commonly right      hepatic from SMA)
** Common origin of coeliac and      SMA
