(27 cards)
Largest blood vessel in the abdomen
aorta
Where does it course?
Courses posterior (superiorly) to anterior (inferiorly)
Where does the aorta supply blood to?
All Abdomen Organs
Where does the branches supply blood to?
To pelvis and lower limbs
Normal diameter of the abdominal aorta is
less than 3 cm
Common Iliac Arteries normal size
less than 1.7 cm
Renal Arteries location
come off aorta laterally, just inferior to the SMA. (an artery)
RT renal artery
passes posterior to the IVC to get to the right kidney.
LT renal vein (LRV)
passes anterior to the aorta/posterior to the SMA to get to the LT kidney.
-Gonadal arteries (testicular/ovarian) are where in the body
Gonads begin to develop next to kidneys before migrating downwards.
Can you see gonadal arteries on ultrasound?
NO
What is the first major branch off the abdominal aorta?
Celiac Axis
where does the Celiac Axis branch into
It branches into the Common Hepatic Artery (CHA), Splenic Artery, and Left Gastric Artery.
what is called ‘Sea Gull or Dove sign”
celiac branches, when imaging transverse aorta
where does the Common Hepatic Artery branch into
into the Proper Hepatic Artery (PHA) and Gastroduodenal Artery (GDA).
Superior Mesenteric Artery (SMA)
Comes off aorta anteriorly about 1 cm inferior to the celiac axis/trunk/artery.
Inferior Mesenteric Artery (IMA)
Comes off aorta anteriorly (around 2 O’clock), inferior to renal arteries.
Inferior Vena Cava and Branches
Lies right of the aorta, posterior to liver. Thinner media layer than the aorta
where does the inferior vena cava take blood to
Returns blood from abdomen and pelvis, lower limbs to the right atrium of the heart.
Normal Size of IVC
Normal Diameter < 2.2 cm, may expand up to 2.5 cm with Valsalva maneuver.
what is IVC formed by and is it posterior or anterior to common iliac arteries
Formed by the union of common iliac veins, posterior to common iliac arteries, at the level of 5th lumbar vertebra.
does IVC run parallel to the aorta?
yes
What side is the IVC and Aorta on
IVC-Right and Aorta-Left
IVC vs Aorta on shape and media size
IVC- almond shaped and thin media
Aorta- Circular shape and thick media
