Philips Abdominal Aortic Aneruysm (AAA) Model Provides Physicians a More Patient Friendly Solution Compared to the Current Standard of Care for Managing AAA Patients

January 27, 2021

Philips Abdominal Aortic Aneurysm (AAA) Model is based on 3D ultrasound, Philips AAA Model delivers clinicians accurate diagnostic information without exposing patients to high doses of radiation and nephrotoxic contrast agents.

An abdominal aortic aneurysm (AAA) is an aneurysm that forms in the lower part of the aorta. Typically, AAAs are identified incidentally during abdominal imaging exams but, in some cases, remain undetected until rupture. A ruptured AAA has an 80% mortality rate [1], emphasizing the importance of routine surveillance. Philips AAA Model integrates innovative software and leading Philips 3D ultrasound technologies into a single solution to help increase diagnostic confidence and an improved patient experience. The software automatically segments and quantifies the size of the aneurysm sac for surveillance of known native (untreated), and post-EVAR (treated) AAAs.

The current standard of care for AAAs includes 2D ultrasound and computed tomography angiography (CTA). Each of these modalities has its drawbacks, including inter-operator variability with 2D ultrasound and patient exposure to high levels of radiation and nephrotoxic contrast agents with CTA.

A recent clinical study showed that 3D ultrasound examination for native AAA surveillance has excellent inter-operator reproducibility, superior to that of 2D ultrasound, supporting the broader use of 3D ultrasound in standard AAA surveillance programs [2]. 3D ultrasound has been shown to estimate the diameter and volume of an AAA with acceptable reproducibility and an improved agreement (over 2D ultrasound) with CT [3]. Furthermore, 3D ultrasound has also been proven to correlate significantly better to 3D CT than 2D ultrasound for assessing the maximum diameter of the residual sac post-EVAR, with clinically acceptable reproducibility [4].

“Regular surveillance of abdominal aortic aneurysm patients is essential, but today’s standard of care has downsides,” said Bich Le, Senior Vice President, General Manager Ultrasound at Philips. “Philips Abdominal Aortic Aneurysm (AAA) Model seamlessly integrates leading Philips technologies including Philips Premium Ultrasound System (EPIQ Elite), Philips Array Transducer (X6-1 xMATRIX) and innovative software into a single solution, to help improve the experience and outcomes for clinicians and patients alike.”

Note: Philips will debut the AAA Model at the LINC (Leipzig Interventional Course) Summit, Europe’s premiere interventional course for vascular specialists, taking place virtually, Jan. 25-29, 2021.

The Philips Abdominal Aortic Aneurysm (AAA) Model is CE marked for sale in Europe and is FDA cleared for sale in the U.S.
