Unit 19: IAC VT STANDARDS Flashcards
If you can’t prove it with your documentation….
It’s meaningless.
What documentation should be obtained?
- B-mode
- Color Doppler
- Doppler waveforms
- Velocity measurements
- MUST BE BILATERAL.
What documentation should be obtained in regards to images obtained?
- Abnormalities: additional images and waveforms that show severity, location, extent, and if possible, etiology.
- Any stenosis or obstruction must have documenation both at and distal to the site.
- Any site of intervention
- ie. stent, bypass in which doppler must be used pre-at-post.
- Any variation in technique/protocol must be described.
What are the 4 specific grayscale images needed?
- CCA
- BIFUR
- ICA
- New: stent must include prox and distal ends.
What are some specific doppler waveforms and velocity measurements needed?
- PCCA
- MID/DISTAL CCA
- PICA
- DICA
- ECA
- VERT
- Any abnormal areas.
What documentation should you obatin from a carotid stent doppler?
- Native artery prox to stent
- Proximal stent
- Mid stent
- Distal stent
- Native artery distal to stent
- Inflow, Stent, Outflow
- Any limitation
A lab must have a __________
single set of written criteria.
What must you interpret in an exam?
- Disease
- Location
- Extent
- Severity
- Etiology when possible.
Must have diagnostic criteria for the interpretation of:
- Plaque morphology
- Doppler waveforms
- Doppler velocities
- Color (if used)
Must interpret ICA stenosis/disease stating how velocity, waveforms, and image are used to document what?
The severity, location, and extent of disease.
CCA and ECA velocity, waveforms and images are used to determine what ?
Greater or less than 50% stenosis
Vertebral velocity, waveforms, and images are used to interpret what?
Steal physiology.
Where must diagnostic criteria be from,?
Published reports or internally generated and validated.
What MUST diagnostic criteria be used on?
- B-mode images
- Spectral Doppler waveforms and velocities
- Color Doppler if used
- Other imaging if used.
