Map It Out
Normal superficial veins are drawn as two parallel lines in this color.
What is black?
Patients should be in this position during assessment of the superficial venous system.
What is standing (upright)?
A positive thrombus finding triggers this examination laterality requirement.
What is a bilateral scan?
The speed of sound in soft tissue.
What is 1540 m/s?
BCBS requires this minimum diameter throughout the segment to be treated for every truncal vein.
What is 3.0mm?
Use this writing tool to draw refluxing superficial veins measuring 3mm or larger.
What is a red marker?
This vein requires two spectral doppler images: spontaneous, phasic flow at rest and response to augmentation.
What is Common Femoral Vein?
When thrombus is visible, measurements in these three dimensions are required.
What are length, width, and height?
This control adjusts echo brightness at different depths to compensate for attenuation.
What is time gain compensation?
The insurance provider that requires an AP measurement of ablated truncal veins during the post ablation scan.
What is United Health Care?
A single curved line(s) labeled IP represents this finding.
What is an incompetent perforator?
A duplicated femoral vein requires these two images.
What are dual screen compression and spectral doppler?
What the acronym ARTE stands for.
What is ablation related thrombus extension?
This doppler mode measures high velocities without aliasing but lacks depth specificty.
What is continuous wave doppler?
Aetna requires this minimum size to ablate truncal veins.
What is 4.5mm?
What brackets drawn on the paper map represent?
What is an epi-fascial segment?
Retrograde flow must exceed this duration for a deep vein to be considered incompetent.
What is 1,000 milliseconds?
The transverse B-mode occlusion assessment records these two measurements along with the ARTE class.
What are the vein diameter and the largest non-compressible area?
At this beam to flow angle, the doppler equation predicts zero doppler shift.
What is 90 degrees?
Anthem specifies SSV reflux over this anatomical span in order for ablation to be covered.
What is from the knee to the ankle?
This symbol indicates that a mapped tributary becomes smaller than 1mm.
What is a starburst?
Under our protocol's spectral display convention, antegrade flow appears here relative to the baseline.
What is below the baseline?
This mobile thrombus feature should always be highlighted when communicating with the provder.
What is a free floating tail?
Narrowing the beam improves the ability to distinguish side by side structures, called this.
What is lateral resolution?
Medicare lists this maximum diameter for VenaSeal and Varithena.
What is 12mm?
