Endovascular aneurysm repair (EVAR) could be an alternative to open aortic surgery as research has shown advantages in patient survival, reduced post-operative complications and shorter hospital lengths of stay. However, 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.

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.
