NIV Arterial AutoSummary Logic
Introduction
The AutoSummary algorithm creates language statements based on non-invasive vessel (NIV) arterial diagrams.
Vessel Diagram Auto-Summary
Lesion Statement Generation
Synapse handles certain segment properties differently because there might be properties for all segments in a lesion.
- Statement will only include the worst Stenosis Ratio.
- Statement will only include the waveform at the worst Stenosis Ratio.
- Statement will only include the worst flow.
Lesion statements display in the following format:
[Doppler Velocities] increased Doppler flow velocities noted in the [vessel segment(s)] [previously treated by/on] [stenosis/restenosis], [other selected segment/lesion properties].
|
Note: |
Synapse uses this format, if the Doppler Velocity is set to Mildly, Moderately, or Severely. |
[Doppler Velocities] Doppler flow velocities noted in the [vessel segment(s)] [previously treated by/on] [stenosis/restenosis], [other selected segment/lesion properties].
|
Note: |
Synapse uses this format, if the Doppler Velocity is set to Diminished or Absent. |
[vessel segment(s)] [previously treated by/on] [stenosis/restenosis], [other selected segment/lesion properties].
Examples
Moderately increased Doppler flow velocities noted in the Left Distal Common Carotid: > 50% stenosis, Large caliber vessel, no spectral broadening.
Diminished Doppler flow velocities noted in the Left Distal External Iliac to Left Mid Superficial Femoral: Severe stenosis, velocity ratio: 6.4.
Right Proximal Superficial Femoral Artery previously treated by drug eluting stent on 5/5/2019.
Graft Statement Generation
Synapse lists the number of grafts visualized and how many are patent, diseased, occluded, or treated.
Graft statements display in the following format:
Graft Type to Vessel segment: [Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]
{segment} to {segment}: [Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]
Sequential graft to {segment} and {segment}:[Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]
Y-graft to {segment} and {segment}: [Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]
Examples
Left Proximal Superficial Femoral Artery to Left Proximal Popliteal Artery graft: Severe 90% stenosis, acute total occlusion, moderately calcified.
Right Proximal Superficial Femoral Artery to Right Proximal Popliteal Artery graft: patent.
Sequential Vein graft from Right Proximal Popliteal Artery to Right Distal Popliteal Artery: patent.
Aneurysm Statement Generation
Aneurysms display in the following format:
Vessel segment: [aneurysm size] aneurysm [selected aneurysm properties/measurements].
Vessel segment(start) to vessel segment (end): [aneurysm size] aneurysm [selected aneurysm properties/measurements].
Example
Distal Aorta: large aneurysm with neck flow measuring 2 cm by 1 cm with a length of 4 cm.
Impressions Rule
The impressions rule populates the statements into the Impression Finding field and Synapse generates statements from the vessel diagram.
Impressions statement generation priority
No Disease
No disease statement occurs if all the vessel group are normal and the study is part of the procedure class for that vessel group. Example: XA.Carotid.
No disease statements display in the following format:
There is no [vessel group] disease.
Example
There is no carotid disease.
Diseased Vessel Groups
Diseased vessel group statements display in the following format:
There is [stenosis value descriptive qualifier] [vessel group] disease.
Examples
There is obstructive lower extremity disease.
Lesions and Aneurysms
Synapse selects the diagnostic statements above to be included in the summary for obstructive or worse lesions and large aneurysms.
Lesions and Aneurysm statements display in the following format:
[Number of grafts] grafts visualized: [number of patent grafts] patent, [number of diseased grafts] diseased, [number of occluded grafts], [number of treated grafts] treated.
