IPV AutoSummary Logic

Introduction

The AutoSummary algorithm creates language statements based on Invasive Peripheral Vascular (IPV) diagrams.

Lesion Statement Generation

Lesion statements display in the following format:

Vessel segment: [Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]

Vessel segment(start) to vessel segment (end), vessel segment (end), and vessel segment (end): [Pre-procedure stenosis]% stenosis, [selected segment/lesion properties]

Examples

Left Distal Common Carotid Artery: Obstructive 70% stenosis, acute total occlusion, moderately calcified, FFR performed: ratio is 0.8.

Left Distal Common Carotid Artery to Left Mid Internal Carotid Artery, and Left Mid External Carotid Artery: Severe 90% stenosis, chronic total occlusion, ulcerated.

Graft Statement Generation

Synapse lists the number of grafts visualized.

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]

Graft statement generation repeats for additional grafts.

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

Aneurysm statements 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.

Interventional Rule

The interventional rule populates the statements into the Interventional Finding field based on diagram dominance, determine anatomical vessel statement order, categorize main vessels, and categorize side branches as described in Diagnostic Findings.

Graft endpoint anastomosis follow the same anatomical order as the native vessels.

Generate Intervention Findings

PCI Lesion Statement Generation

The statements includes aneurysms and lesion if both are present. Stents that do not treat the entire lesion state the abbreviated segment range after the treatment.

PCI lesions statements display in the following format

Vessel segment: [Pre-procedure stenosis]% stenosis treated with [list of associated treatments with associated inventory items]. [post-procedure stenosis]% residual stenosis. [Successful/Unsuccessful] intervention.

Vessel segment(start) to vessel segment (end): [Pre-procedure stenosis]% stenosis treated with [list of associated treatments with associated inventory items]. [post-procedure stenosis]% residual stenosis. Successful/Unsuccessful] intervention.

Main Vessel segment(start) to main vessel segment (end): [aneurysm size]% aneurysm treated with [list of associated treatments with associated inventory items. Successful/Unsuccessful] intervention.

Examples

Left Distal Common Carotid Artery: 70% stenosis treated with Pronto LP Aspiration Catheter 6F, TREK RX 2.5mm X 15mm, two NC TREK RX 3mm X 15mm, SYNERGY 4.00X38MM, and NC TREK RX 4mm X 12mm. 0% residual stenosis. Successful intervention.

Left Distal Common Carotid Artery to Left Mid Internal Carotid, and Left Mid External Carotid: 90% stenosis treated two NC TREK RX 3mm X 15mm, and SYNERGY 4.00 X 38M. 0% residual stenosis. Successful intervention.

Proximal Aorta to Right Distal Common Iliac Artery, and Left Distal Common Iliac Artery: large aneurysm treated with AneuRx Stent Graft.

Impressions Rule

The impressions rule populates statements into the Impression Finding field. Statement Generation is from the vessel diagram.

Impressions Statement Generation Priority

Interventions

  • Stent graft treatments including the Ao but not in the Iliac are assumed to be a Thoracic EVAR.
  • Stent Grafts that are include Aorta segments as well as right and left iliac segments are assumed to be EVAR.
  • Stent Grafts that are include Aorta segments but not right and left iliac segments are assumed to be Thoracic EVAR.

Intervention statements display in the following format:

[Vessel segment] was successfully treated with a [treatment type].

Example

Left Distal Common Carotid Artery was successfully treated with a Drug Eluting Stent.

Proximal Aorta to Right Distal Common Iliac Artery, and Left Distal Common Iliac Artery was treated with an EVAR.

No Diseased Groups

The no diseased groups statement applies only if all vessels within a group are normal and the study is part of the procedure class for that vessel group. Example:

XA.Carotid

No diseased vessel group 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

The diagnostic statements above are selected and included in the summary for obstructive or worse lesions and large aneurysms.

[Number of grafts] grafts visualized: [number of patent grafts] patent, [number of diseased grafts] diseased, [number of occluded grafts], [number of treated grafts] treated.
