O'Banion at al reported the POPSAVEIT score for evaluating traumatic injury to the popliteal artery. This can help to identify a patient who may require more aggressive management. The authors are from multiple institutions in the United States.
Patient selection: trauma to the popliteal artery
Parameters:
(1) initial systolic blood pressure in mm Hg
(2) associated orthopedic injury
(3) pedal arterial findings

= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 5
• A score >= 3 is associated with high risk of amputation.
Performance:
• The area under the ROC curve is 0.75.
