Abdominal Aortic Aneurysm Model

Philips Abdominal Aortic Aneurysm Model

 

Designed to detect, segment and quantify 3D ultrasound date for use in surveillance of native and post-endovascular aneurysm repair (EVAR) AAAs.

    Abdominal aortic aneurysms (AAAs) cause more than 175,000 deaths globally every year 1


    Abdominal aortic aneurysms cause more than 175,000 deaths globally every year, with an 80% mortality rate if ruptured1. Routine surveillance is important, yet imaging modalities in the current standard of care are associated with significant drawbacks: inter-operator variability with 2D ultrasound and patient exposure to high levels of radiation and nephrotoxic contrast agents with CTA.

    Watch the video to learn how Philips AAA Model overcomes these drawbacks with:
     

    • Increased diagnostic confidence
    • Improved patient experience
    • Lowered cost of care

    Improved patient experience


    Philips AAA Model improves the patient experience by eliminating exposure to high levels of radiation and nephrotoxic contrast agents, while still providing clinicians with the necessary diagnostic information.

     

    It has been shown that 3D ultrasound can be used to estimate the diameter and volume of an AAA with acceptable reproducibility and an improved agreement with CT2.

    3D ultrasound also correlates significantly better to 3D CT than the currently used method of 2D ultrasound when assessing maximum diameter of the residual sac after EVAR, with clinically acceptable reproducibility3.

    Increased diagnostic confidence


    For surveillance of a native AAA by measuring the maximum AP diameter of the aneurysm, it has been shown that a 3D ultrasound exam can be used with inter-operator reproducibility superior to that of a 2D ultrasound exam5.

    The maximal diameter of an AAA is ideally measured perpendicular to the centerline, a methodology that so far has only been feasible with 3D CT and magnetic resonance angiography (MRA)5. Philips AAA Model provides the centerline of the AAA throughout the volume of the 3D acquisition, making 3D ultrasound now also feasible with this methodology.

    Philips AAA Model also provides the partial volume of the aneurysm which is beneficial as it has been observed that more than one-third of small AAAs, considered to be stable based on diameter alone, were actually growing in volume6.

    Lowered cost of care  


    The low cost of ultrasound, combined with the absence of both radiation exposure and administration of nephrotoxic contrast agents to the patient, has made it the preferred imaging modality for aneurysm screening and surveillance7.
