Vascular ARDMS Exam Questions And Accurate Answers
Average velocity of the aorta - ANSWER 60-100 cm/s
what aortic pathologies affect the branches - ANSWER stenosis, aneurysm, plaque
what are the normal waveforms of the proximal aorta - ANSWER low resistance flow
pattern with continuous forward diastolic flow by the liver spleen, and kidneys (similar
to ICA waveform)
normal waveforms for distal aorta - ANSWER higher resistance flow pattern
what is responsible for the distal aorta being more high resistive - ANSWER peripheral
resistance and because of the triphasic nature of the aortic branches (reversal during
diastole)
why is the proximal aorta more high low resistive - ANSWER due to the highly metabolic
organs of the abdomen requiring forward flow in systole and diastole
what is the most superior brunch of the aorta arising from the anterior surface -
ANSWER celiac artery
where to 95% of celiac arteries bif - ANSWER 1-3 cm from origin
what does the eliac artery bif into - ANSWER common hepatic, splenic, and left gastric
which pane is the celiac best seen in - ANSWER transverse
,what is the normal waveform for the celiac - ANSWER low resistance flow due to the
vascular beds of the liver and spleen with continuous forward flow during diastole
if occlusion of the celiac occurs, what happens - ANSWER collateralization via the
pancreaticoduodenal arterial arcade-network of small vessels surrounding the
pancreas and duodenum feeding into duodenum then into the common hepatic
how does the splenic artery course - ANSWER it takes a tortuous course along the
posterior, superior pancreatic body and tail with numerous pancreatic and gastric
branches
where does the splenic artery arise- ANSWER it is a branch off of the celiac axis
where does the splenic artery terminate- ANSWER ends as branches in the splenic
hilum
what is the normal splenic artery waveform- ANSWER turbulent flow due to tortuosity fig
26-3, 441
What is the best way to evaluate the spenic artery ANSWER - in the transverse plane
from the anterior midline along the tail, eval distal from left lateral window at splenic
hilum
Where does the common hepatic artery lay ANSWER - in the superior border of the
pancreatic head, its the right branch of the celiac
What does the common hepatic give rise to ANSWER - The GDA
-distal to which structure does the common hepatic become the proper hepatic artery
ANSWER beyond the GDA
, -when the proper hepatic artery actually reaches the liver, what happens to it there -
ANSWER It then splits into right and left branches
-the normal wave form for the common hepatic artery is - ANSWER low resistance
continuous forward diastolic flow
Where would one best evaluate the common hepatic artery? - ANSWER evaluate from
anterior abdominal window at the porta hepatis
Where is the origin of the SMA? - ANSWER anterior aorta distal to celiac trunk
Describe the course of the SMA - ANSWER It has a short anterior segment then turns
inferiorly and terminates near the ileoceccal valve
What is the normal waveform of the SMA and IMA in a fasting patient ANSWER high
resistance flow with sharp systolic peaks and absent late diastolic flow
What is the normal waveform of the SMA and IMA 30-90 minutes post prandial ANSWER
low resistance pattern with broad systolic peaks and continuous diastolic flow
Whats the best way to eval the SMA and IMA? ANSWER Eval in transverse from anterior
What does the SMA supply? ANSWER branches supply the jejunum, ileum, cecum,
ascending colon, proximal 2/3rds of the transverse colon, portions of the duodenum,
and the pancreatic head
Where is the SMA in relation to the SMV and the left renal vein?
Anime Normally, to the right of the SMV, and left renal vein courses between the SMA
and aorta.
What does the portal venous system serve to do?
Anime Carry nutrient-rich blood from the intestines and spleen to the liver.
