Penny Review Chapter 9: Abdominal Vasculature
The diameter of the IVC should never exceed
2.5cm
A disorder of the connective tissue characterized by tall stature and aortic and mitral valve insufficiency is
Marfan syndrome
an outpatient with a hx of back pain and hypertension presents with a 6cm infrarenal aortic aneurysm with an echogenic linear structure noted gently swaying in the lumen. what is this
aortic dissection
occlusion of the hepatic veins describe
budd chiari syndrome
which of the following would most likely yield a high resistance flow pattern celiac artery common iliac artery splenic artery right renal artery
common iliac artery
which of the following vessels would most likely yield a high resistance flow pattern celiac artery common hepatic artery renal artery fasting SMA
fasting SMA
what flow pattern would the postpradial SMA yield in a small bowel ischemia
high resistance
what vessel may attach to the splenic vein before reaching the portal confluence
inferior mesenteric vein
a patient presents with a hx of marfan syndrome. the sono eval reveals a linear echo within the aortic lumen that extends fro the celiac axis to the iliac arteries. color doppler reveals flow through the aorta on both sides of the linear echo. The patient has had no surgeries and there is no AAA. what does the linear echo most likely represent
intimal flap
what vessel can be often noted coursing between the SMA and the abd aorta in the trv scan plane
left renal vein
Enlargement of the IVC, with subsequent enlargement of the hepatic veins, is seen in cases of
right sided heart failure
which of the following is not true about the abd aorta -it bifurcates into the CIA's -the prox aorta is situated more anterior than the distal aorta -the aorta has a thicker tunica media than the IVC -the third major branches of the abd aorta are the renal arteries
the prox aorta is situated more anterior than the distal aorta (the distal aorta is more anterior and the prox aorta is deeper)
the outer wall layer of a vessel is
tunica adventitia
clinical findings of AAA include all of the following except lower extremity pain back pain abd bruit elevated hematocrit
elevated hematocrit
what vascular structure may be confused for the main panc duct
splenic artery
a patient with unexplained abd pain comes in for vascular assessment of SMA. you note the SMA yields a persistent high resistance flow pattern. this is indicitave of
small bowel ischemia
which of the following is not a section of the IVC post renal pancreatic pre renal hepatic
pancreatic
what vessel travels directly anterior to the left renal artery
left renal vein
what should postpradial flow pattern be within the SMA
low resistance (high resistance flow while fasting, should switch to low resistance after eating- if not: think BOWEL ISCHEMIA)
all of the following are branches of the celiac axis except right gastric artery hepatic artery splenic artery left gastric artery
right gastric artery (hepatic artery and splenic artery comming off the celiac trunk in trv forms the seagull sign)
AAA is present when the diameter measures more than
3cm
An aneurysm associated with infection is termed
Mycotic
The second main branch off the abd aorta is the
SMA
what vessel shows a different flow pattern after eating
SMA
the main portal vein is created by the
SMA and splenic vein
the first major branch off the abd aorta is
celiac axis/artery/trunk
what abnormality would the failure of an eval to isolate an aneurysm from circulation most likely result in
endoleak
the most common shape of an AAA is
fusiform
what branch and its tributaries of the abd aorta appears as a seagull sign in the trv plane
hepatic artery and splenic artery that come off the CELIAC ARTERY
the veins seen attaching to the IVC just below the diaphragm are the
hepatic veins
which of the following would have a pulsatile triphasic blood flow pattern renal veins hepatic veins gonadal veins common iliac veins
hepatic veins
the left gonadal vein drains into the
left renal vein
the aorta originates at the
left ventricle
which of the following statements about the IVC is not true the diameter is variable respiration can affect the size located to the left of the aorta considered retroperitoneal
located to the left of the aorta the IVC is located to the right of the aorta**
the hepatic artery should demonstrate what wave form
low resistance
which of the following statements about the abd aorta is not true -most aneurysms located within the aorta are false aneurysms -located just left of the midline -most common location of an AAA is infrarenal -considered retroperitoneal
most aneurysms are false (most are true**)
the IVC terminates at the
right atrium
in the sag plane, you see a circular, anechoic vascular structure posterior to the IVC. Which of the following would this structure most likely be abdominal aorta left renal vein right renal artery SMA
right renal artery
what vessel is shortest in length right renal vein right renal artery left renal vein left renal artery
right renal vein
The inner wall layer of a vessel, closest to the passing blood, is the:
tunica intima
