URR vascular - surgery, physiologic
exams, procedures prep & reporting
a patient presents with an order for a lower extremity venous doppler exam to rule out DVT. this patient
should be evaluated in the _____ position in order to _______ - - semi-erect

- increase hydrostatic pressure



when evaluating a suspected thoracic outlet syndrome, a PPG exam can be performed with the sensor
placed on the ____ or a doppler exam can be performed with transducer place _____ - - 2nd digit

- on the radial artery



which of the following will increase the amplitude of a Digital PPG tracing? - warming the patients
foot and toes



a pt presents with dysphagia and hoarseness. the physician suspects Ortner syndrome. what type of
exam will you be performing? - upper extremity arterial duplex exam



indications for ABI: - - femoral bruit

- diminished pulses

- pt's > 50 years with diabetes or smoking hx

- all pt's > 70 years



what system setting would result in a false-positive findings for reflux in the GSV? - high color
persistance settings



what system adjustment is made when changing from a LE extremity arterial exam to a LE venous exam?
- decrease doppler scale



_______ is the gold standard in testing for arterial disease - angiography

,angiography evaluates the _______ axis of the vessel which can lead to ________ of the stenosis -
- longitudinal axis

- over or under-estimation of the stenosis



what is displayed on the y-axis on a doppler tracing? - frequency shift



what is true regarding intraoperative duplex evaluation during a carotid endarterectomy? - -
highest probe frequency is preferred

- technique is used to assess immediate flow changes

- probe is placed in direct contact on the vessel so sterile technique is required



radio frequency venous ablation requires: - sterile technique



a LE venous doppler that is performed for suspected DVT should be performed with the pt in the _____
position - reverse trendelenburg



when evaluating a pregnant patient for DVT, the patient should be placed in the ______ position -
left oblique or decubitus



which blood vessel is commonly evaluated with doppler to obtain the thigh pressure when performing a
segmental pressure exam? - distal calf artery with highest ankle pressure



if your give NPV, PPV, sensitive and specificity how do you find accuracy? - accuracy falls

- between the NPV and PPV

and

- between specificity and sensitivity



which modality is preferred to diagnose FMD in the circle of willis? - angiography



if new research shows that the minimum velocity criteria used to diagnose >60% renal artery stenosis

, If the AT is >140ms in both common femoral arteries:

a.) bilateral internal iliac disease is suspected

b.) flow is considered normal

c.) unilateral external iliac disease is suspected

d.) aortic disease is suspected - d.) aortic disease is suspected



a proximal femoral artery stenosis will cause the _________ in the mid femoral artery -
*acceleration time to decrease*

(low resistant vessels and areas distal to stenosis will have longer AT)



pulsatility index can be used to describe: - the amount of variation in the velocity during the
cardiac cycle



D-dimer levels are most accurate for predicting: - the absence of DVT



which technique can be used to assess the presence and timing of reflux in multiple vessels
simultaneously? - color doppler



which exam would be improved by the administration of simethicone prior to the ultrasound? -
renal artery duplex

- medication that reduces bowel gas



a pt with a recent subdural hematoma. what is physician looking for on the TCD exam? -
vasospasm



the LE segmental pressure exam is most commonly performed with an _____ to obtain the doppler
signal for the pressure measurements of the ankle - 8-10 MHz CW doppler probe



why is an acute arterial occlusion in the lower extremity considered a critical finding? - collaterals
have not had time to form to redistribute the blood
