Summary
The purpose of the study is to describe Sodium Fluoride uptake (using Positron Emission Tomography-Computed Tomography - PET-CT) following Endovascular Aneurysm Repair (EVAR) and to determine whether Sodium Fluoride PET-CT can predict the development of endoleaks.
Description
Abdominal aortic aneurysms are a leading cause of death in the United Kingdom. Surveillance programmes and pre-emptive surgical repair are lifesaving. Traditional open surgical repair is associated with major perioperative morbidity and mortality and there has been a move towards minimally invasive Endovascular Aneurysm Repair (EVAR), which reduces these early risks. However, the cost effectiveness and long-term clinical effectiveness of EVAR is undermined by concerns of durability due to the development of endoleaks and late aneurysm rupture secondary to progression of native aortic aneurysm disease and stent graft failure. It has previously been demonstrated that 18F-Sodium Fluoride Positron Emission Tomography can predict progression of aneurysm disease and is associated with greater rates of abdominal aortic aneurysm expansion and the future risk of rupture or surgical repair.
The investigators here wish to examine whether 18F-Sodium Fluoride on Positron Emission Tomography uptake (i) is increased in patients with endoleaks or related complications, (ii) can prospectively predict the likelihood of developing endoleaks in patients undergoing EVAR, and (ii) is a feasible approach to select patients for EVAR with a reduced future risk of stent graft failure and re-intervention. The investigators believe that there is a compelling scientific rationale for this approach with major translational potential to better select subgroups of patients for EVAR and ultimately improve their outcome.
