vascular ultrasound questions
a carotid duplex exam documents a possible occlusion of the Rt ICA what other
noninvasive finding would help confirm the presence of occlusion? - ✔️✔️- accelerated
flow in the ipsilateral or contralateral vertebral artery
-accelerated flowing in the ipsilateral ECA
-high resistance flow in the ipsilateral CCA
what are the common stroke symptoms? - ✔️✔️numbness,
weakness
double vision
confusion
trouble walking
allintermittent claudication - ✔️✔️there is a pressure drop distal to the obstructed
segment after exercise
all of the following are considered peripheral arteries (high resistant) - ✔️✔️PTA
Brachial
radial

a 58 year old is being evaluated for dizziness- what disease process is most likely to
cause the symptom? - ✔️✔️vertebrobasilar insufficiency (VBI)
all of the following are paired veins? - ✔️✔️radial
ulnar
PTV
, ATV
brachial
the ICA terminates into what vessels? - ✔️✔️MCA and ACA
a PSV of >275 cm/sec associated with post stenotic turbulence must be evident to
suggest a >70% diameter reduction of SMA - ✔️✔️
what mechanism can adequately perfuse the rt hemisphere when a possible occlusion
of the right ICA? - ✔️✔️rt vertebral to right poster cerebral art to rt post communicating
art into rt ACA and/or rt MCA
-lt ICA to ACA to rt ACA and RT MCA
