hi let's talk about the celiac trunk the celiac trunk is the first major anterior branch of the
abdominal aorta coming off at about the level of t12 going out to the viscera it's the dominant
blood supply to the derivatives of the embryonic forget and typically the trunk itself is not all
that impressive it's very short but there are three branches that are quite lovely
we have superiorly here the left gastric artery the left gastric artery is going to
supply blood up to the esophagus it's also going to be one of the dominant blood supplies to the
lesser curvature of the stomach and its branches will fall over both sides of the stomach
there's also a splenic artery we'll see more of that in a little while
and a common hepatic artery we'll see more of that in a little while as well
so let's turn our attention to that common hepatic artery trace out the trunk for you right
there the common hepatic artery has two major branches the hepatic artery proper or hap
for short and the gastroduodenal artery the hepatic artery proper we can see it's kind of
there's a little bit of torsion to it there but it's coming out that way there's a vein
interrupting our view there we can see one of the early branches of hap the right gastric artery
coming down along the lesser curvature of the stomach that right gastric artery anastomosis
with the left gastric artery which we can see here to supply the lesser curvature of the stomach so
any of the gastric arteries those are lesser curvature branches so you can see the the right
gastric there coming off from the hepatic artery proper the hepatic artery proper then also has
left and right branches so that's the left branch
left branch of the hepatic artery proper and then that's the right branch of hepatic artery
proper which is going to be the origin for the cystic artery that that we can see in a moment
the other branch of the common hepatic which is about there is the gastroduodenal artery
that gastroduodenal artery is going to give rise to the right gastro-omental artery which we can
see coming across there that's going to serve the stomach and the greater momentum along the greater
curvature that's met by the left gastro-omental artery which is a branch of the splenic
another term for gastro-omental is gastro-epiploic and so you can you can say either those are
interchangeable and those gastro elemental arteries will have both gastric branches
serving the stomach and omental branches serving the omentum here we can see a better view of the
hepatic artery proper here so here is hat coming up this way and here we can see the left branch
of hap and here we can see the right branch of hap and coming off of the right branch right there
tucked away behind the common hepatic duct is the cystic artery heading out to and serving
the gallbladder the cystic artery as you may recall can reliably be found within the
hepatobiliary triangle that hepatobiliary triangle has three sides to it there's the cystic duct
there's the common hepatic duct and then there's the visceral surface of the liver
and we can see here that yes indeed that cystic duct is being conveyed through the hepatobiliary
triangle oh so wonderful and then finally the the splenic artery in this session we're not yet at
the point where we'll have reflected the stomach away and moved through the the pancreas to see
this but we can see the uh the distal portion of the splenic artery here and we can see exactly how
torturous and curvy that is so that splenic artery will give off short gastric branches
which we can see here those short gastric branches are serving the the fundus of the stomach it's
also going to give off splenic branches to the spleen and then finally the left gastro-omental
artery you can see winding down around here or left gastroepiploic artery which will anastomose
with the right gastro-omental artery of the gastroduodenal artery and like its counterpart
it has both gastric branches and omental branches so we've discussed the celiac trunk
and its branches and their branches and what they serve thank you very much for your time
