What is not a cause of renal vascular hypertension?
- Rental artery stenosis
- Athrersceropsis
- FMD

PVT
What w ould be an abnormal renal artery to aortic ratio?
Greater then 3.5
What is an abnormal RI calculated in the intracranial arteries?
0.8
What ultrasound features in normally seen in a renal transplant?
Post-op Enlargement
What feature could possibly indicate an renal allogaraft rejection?
- Fluid collection
- Absent diastolic flow in the renal artery
- Renal vein thrombosis
- Psydoanyrsms
Absent diastolic flow in the renal artery
What are two ultrasonic features of a renal vein thrombosis?
Enlarged kidney, distended renal vein
What is the most common vascular complication in renal transplant patients?
1. Cyclosporine toxicity
2. Venosus thrombosis
3. Arterial stenosis
4. Pseudoaneurysm
Arterial stenosis
The hailer regions and intracranial arteries should ideally be insonated at 60degrees? T/F
False should be at zero
Which collateral pathway link the celiac and SMA via arterial branches surrounding the duodenum?
Pancreaticoduodenal arcade
Duplex ultrasound is the most likely to be used to diagnose acute mesenteric ischemia? T/F?
False (We can do chronic)
Which of the following splanchnic vessels are least affected by food consumption
- IMA
- SMA
- Celiac Axis
- Renal artery
Celiac Axis
(Renal is not a choice because it is not splanchnic)
What feature indicates a celiac stenosis >70%?
- PSV >200cm/s
- Celiac artery/ aorta PSV ratio >3.5
- Reversed flow in the GDA or common hepatic artery
- All of the above
- PSV >200cm/s
- Celiac artery/ aorta PSV ratio >3.5
- Reversed flow in the GDA or common hepatic artery
- All of the above
Quite respiration is the best breathing tech to confirm median arcuate ligament compression. T/F?
False, Expiration where the ligament will pull up on the artery and cause an occlusion
WHat might result from splanchnic vein occlusion?
- Bowel ischemia
- Hypotension
- Emboli
- Small vessel ischemia?
Bowel ischemia
Pre-prandial pain is least likely to be associated with chronic mesenteric ischemia? T/F?
True, post prandial pain is associated with chronic mesenteric ischemia
Why is i it best practice to perform a standard upper extremity DVT scan with dialysis patients?
Subclavian vein thrombosis is often seen in dialysis patients
The arterial limb is the most common site for stenosis in a dialysis graft? T/F?
False, Venous limb is the most common
Which of the following is a possible characteristic of graft/ fistula occlusion?
- High resistance in feeding artery
- Low resistance above the anastomosis
- High resistance below the anastomosis
- PSV of 385 cm/s DEV 150cm/sec
High resistance in feeding artery
Which of the following is a possible finding of stenosis/ occlusion of the main renal artery?
- Tarsus parvus waveform in a segmental renal artery
- Staccatos waveform in segmental renal artery
Tardus parvus waveform in a segmental renal artery
A urinary tract infection could cause an RI >0.8 in the kidney ? T/F?
True
What is a not a possible U/S finding in chronic renal vein thrombosis?
- Hematuria
- Small renal size
- Enlarged kidney
- Collateral vasculature
Hematuria, Hematuria is NOT a u/s finding
How does renovacscular disease lead to hypertension?
Causes renal ischemia triggering the renin-angiotensin mechanism
Which of the following is nota potential cause of renal artery stenosis
- FMD
- Atherosclerosis
- Uncontrollable hypertension
- Extrinsic compression by a tumor
Uncontrollable hypertension
Which of the following is not a normal finding for a hemodialysis graft or fistula?
1. High flow state
2. <5mm from the skin surface
3. Turbulent, pulsatile waveform
4. Low resistance with increased PSV and EDV
Turbulent, pulsatile waveform
