The study was awarded funding by the NIHR under their Invention for Innovation (i4i) programme.
Cambridge, United Kingdom - Cydar Medical, in partnership with King’s College London, has today announced it has initiated the ARIA Study: a randomised controlled trial to assess the clinical, technical and cost-effectiveness of a cloud-based, ARtificially Intelligent image fusion system in comparison to standard treatment to guide endovascular Aortic aneurysm repair (ARIA),
Endovascular aneurysm repair (EVAR) is an alternative to open aortic surgery due to perceived advantages in patient survival, reduced post-operative complications and shorter hospital lengths of stay.(1) Despite these potential advantages, there is still significant variability in pre-operative planning and sizing, problems associated with imprecise visualisation and device positioning intra-operatively, and inconsistent patient outcomes.
“Our central hypothesis is that digital technology - specifically cloud-computing and artificial intelligence (AI), can be used to assess and learn from large volumes of data to inform clinical decision making and has the potential to improve the predictability of individual patient outcomes and the consistency of outcomes in the NHS, “said Dr Rachel Clough, Principal Investigator of the ARIA Study and Clinical Senior Lecturer from King’s College London.
The randomised trial will enrol 340 patients in 10 sites across the UK with a clinical diagnosis of abdominal aortic or thoracoabdominal aortic aneurysm (AAA and TAAA respectively) suitable for endovascular treatment. The trial will follow patients for one year and assess the effect of Cydar EV Maps on clinical-, technical- and cost-effectiveness in comparison to standard treatment in endovascular aortic aneurysm repair, used for both standard and complex devices.
The study was initiated with the first patient enrolled at the Liverpool University Hospitals NHS Foundation Trust. “Cydar EV Maps is a game-changing technology for vascular navigation. The ARIA study provides a unique opportunity to demonstrate the benefits like reduced procedure time and reduction to radiation exposure, although some of the more subtle benefits related to procedural quality and reduced operator fatigue may never be directly measured but are obvious as an operator,” said Dr Simon Neequaye, Principal Investigator at the Liverpool University Hospital NHS Foundation Trust.
Cydar EV Maps is the first product from Cydar Medical’s integrated software solutions system. It is simple to integrate with the existing imaging hardware that is present in all hospitals undertaking endovascular surgery.
Cydar EV Maps is currently available in the EU, UK and US. It is certified Software-as-a-Medical Device with an EU CE mark and U.S. FDA 510(k) clearance.

Cydar specializes in medical computer vision, machine learning and cloud high-performance computing. Cydar EV Maps is cloud-based software that generates patient specific 3D Maps of soft tissue vasculature to support more effective image guided, minimally invasive endovascular surgery. The system comprises pre-operative procedure planning functionality and real time, AI enabled 3D intra-operative imaging and procedure guidance, with procedure video capture and post procedure review functions.
When guidewires and instruments deform blood vessel, the real-time imaging updates the Map to match the new, deformed patient anatomy. This results in an accurate 3D Map on the screen throughout a procedure. The Cydar EV Maps platform also allows post procedure outcome analysis. The result of this integration of procedure planning, guidance and review is that surgeons can work more accurately and efficiently – enabling an ~50%(2) reduction in radiation exposure, a significant reduction in fluoroscopy time and reducing procedure times by more than 20%(3) while helping achieve better outcomes for patients.
Cydar’s Surgical Augmented Intelligence technology is learning from every case to develop a deeper understanding of surgery. Headquartered in Cambridge, UK, Cydar’s focus is to build a future where all procedures proceed exactly as planned News about Cydar can be found at www.cydarmedical.com/news
