abdominal aorta anatomy Flashcards
visceral branches of the abd ao
celiac trunk
superior mesenteric artery
renal arteries
inferior mesenteric artery
what are the terminal branches of the aortic arch
common iliac artery (CIA)
CA branches
left gastric
splenic
common hepatic
what does the CA supply
stomach liver pancreas duodenum spleen
SMA supplies
sm intestine
cecum
parts of colon
where is anatomical variant of SMA
common trunk w/ the CA
otherwise 1cm below CA usually
renal arteries supply
kidneys
suprarenal glands
ureters
normal anatomical variant of renal arteries
multiple renal arteries are common
they lie posterior to the renal veins
right renal artery
coarse - to the ivc
posterior
the RRA courses posterior to the IVC
in TRV a landmark for the LRA is the - which crosses the aorta anteriorly
left renal vein
the artery is just posterior to the renal vein
the CIA supply
pelvis
abdominal wall
lower limbs
CIA bifurcates into
internal iliac arteries (hypogastric)
external iliac artery
internal iliac artery travels along what muscle
psoas major m.
after passing under what ligament the EIA becomes what
inguinal ligament
CFA ( common femoral artery )
IMA comes off of the abdominal aorta at -O’clock
2 o’clock
collaterals for mesenteric flow
(2)
conn what two vessels
marginal artery of drummond
arch of Riolan (AOR)
internal iliac is also called
hypogastric
IIA
inferior mesenteric artery supplies
transverse & descending colon
part of cecum
IMA arises from abd ao - to - cm above the bifurcation
3-4 cm
the IMA can act as a collateral connection in - aortic occlusion and
AOR provides collateral flow from SMA (prox) to IMA (prox) to Iliac vessels via superior rectal artery
AOR provides collateral flow in what occasion
prox SMA occlusion
provides collateral flow from the IMA to the SMA territory
what does the marginal artery of Drummond connect
SMA and IMA
it becomes a collateral in the case of occlusion of one of these vessels .
