| Question | Answer |
| Causes of CVA | embolism thrombosis hemorrhage |
| Which attack resolves the symptoms within 24 hours? TIA or RIND | Transient Ischemic Attack - resolve in 24hrs Reversible Ischemic Neurologic deficit (RIND)- symptoms resolve but NOT w/in 24hrs |
| Amaurosis Fugax/TMB is related to ipsilateral or contralateral? | IPSILATERAL |
| The best acoustic window for the ICA is the.. | posterior-lateral approach |
| What are 4 ways to differentiate the ICA from the ECA? | 1. ECA has extracranial branches,ICA doesnt 2. ECA is high resistant 3. ICA is usually larger in diameter than ECA 4. ECA can be identified by the Temporal Tap |
| Which flow can be seen at the bulb area? | flow seperation or "eddy flow" |
| If the doppler gain is set to high, which type of flow can it mimic? | Turbulence Flow |
| What can be used on the machine to detect "trickle flow"? | Low PRF or power doppler |
| String of Pearls is a sign of .... and occurs where? | Fibromuscular Dysplasia (FMD)- Distal segment of the cervical portion of the ICA |
| a condition in which delamination occurs | Carotid Dissection |
| The % diameter reduction was obtained by measuring the residual lumen (RL) and the true diameter (TL) at the "same" location aka bulb diameter stenosis is which method? | The traditional "BULB METHOD" |
| TRUE OR FALSE: Velocity acceleration occurs @ 60% but some consider 50% the threshold. | TRUE |
| TRUE OR FALSE SRU guidlines uses the 50% threshold with post chaotic turbulence | TRUE stenosis must measure 50 or greater but with velocity acceleration and post turbulance |
| TRUE OR FALSE Expect LOWER velocities in an ICA stent | FALSE higher velocities because stents do not restore arterial lumen to normal size |
| plaque ulceration should be reported if it exceeds .... mm | 2mm |
| Which plaque characterization has an "egg-shell appearance" ? | Intraplaque hemorrhage (IPH) |
| common hemisheric symptoms associated with the contralateral hemisphere | paresthesia, hemiparesis, hemiplegia, ataxia |
| which angle is doppler beam parallel to flow | zero degree angle |
| blood velocity may increase or decrease in a normal distal ICA | increase |
| doppler angels should not exceed | 60 degrees |
| hemispheric ischemia, headache, ipsilateral neck pain are symptoms of what | Carotid Dissection |
| These conditions occurs more in women | FMD and Carotid Dissection |
