ARDMS Vascular Technology (VT) Exam

Question 1

A patient with refractory hypertension is referred for a renal artery duplex exam. The peak systolic velocity (PSV) in the suprarenal aorta is 80 cm/s. The highest PSV obtained in the proximal right renal artery is 300 cm/s. What is the calculated Renal-Aortic Ratio (RAR), and what is the most likely interpretation?

RAR is 3.75, suggestive of a hemodynamically significant stenosis (>60%). RAR is 0.27, which is within normal limits. RAR is 3.75, which is within normal limits. RAR is 2.50, suggestive of a non-hemodynamically significant stenosis (<50%).

Correct Answer:

RAR is 3.75, suggestive of a hemodynamically significant stenosis (>60%).

Question 2

When measuring the maximum diameter of an abdominal aortic aneurysm (AAA) via duplex ultrasound for surveillance, which of the following is the standard, most reproducible technique?

Anterior-posterior diameter measured from inner wall to inner wall in a sagittal plane. Anterior-posterior diameter measured from outer wall to outer wall in a transverse plane. Lumen diameter only, excluding any mural thrombus, in a transverse plane. Transverse diameter measured from outer wall to outer wall in a sagittal plane.

Correct Answer:

Anterior-posterior diameter measured from outer wall to outer wall in a transverse plane.

Question 3

A 40-year-old patient presents with post-prandial epigastric pain. During a mesenteric duplex exam, the celiac artery PSV is 140 cm/s during quiet inspiration. When the patient performs a deep expiration, the PSV increases sharply to 360 cm/s with associated post-stenotic turbulence. These findings are most characteristic of:

Atherosclerotic celiac artery stenosis. Celiac artery dissection. Median Arcuate Ligament Syndrome (MALS). Superior Mesenteric Artery (SMA) syndrome.

Correct Answer:

Median Arcuate Ligament Syndrome (MALS).

Question 4

A patient with a history of chronic liver disease undergoes an abdominal duplex exam. Which of the following findings is the most specific indicator of severe portal hypertension?

A main portal vein diameter of 14 mm. Splenomegaly with a spleen length of 15 cm. A continuous, non-phasic waveform in the hepatic veins. Hepatofugal (reversed) flow in the main portal vein.

Correct Answer:

Hepatofugal (reversed) flow in the main portal vein.

Question 5

A patient with ascites, hepatomegaly, and abdominal pain is referred for an abdominal vascular duplex exam. Which of the following findings would be most consistent with a diagnosis of Budd-Chiari syndrome?

Absence of detectable flow or visualization of thrombus within the major hepatic veins. A highly pulsatile, 'to-and-fro' waveform in the main portal vein. Markedly elevated velocities (>400 cm/s) in the superior mesenteric artery. A patent Transjugular Intrahepatic Portosystemic Shunt (TIPS).

Correct Answer:

Absence of detectable flow or visualization of thrombus within the major hepatic veins.
