Abdominal aortic aneurysms
The medical treatment of abdominal aortic aneurysms is one of the major challenges in vascular pathology. MRI, applied to experimental animal models, and as a diagnostic tool in humans is a method of choice to follow the development of aneurysms morphologically and haemodynamically. Experimental animal models of aneurysms allow the study of pathophysiology and the appropriateness of diagnostic approaches. Animal models of abdominal aortic aneurysms have been developed in the team to monitor the development of the aneurysm and to study the choice of therapeutic management by evaluating the anchoring zone of aortic stents in order to optimise their positioning and limit the risk of endoleaks.
The aim is to develop new biomechanical markers of the aorta with functional MRI (rest and effort), for diagnostic and therapeutic purposes, on patients with congenital pathology
The CVS team develops time-resolved flow imaging methods in preclinical and clinical settings.
Clinical vascular MRI:
The CVS team is implementing MRI during effort to explore the biomechanical properties of the ascending aorta and arch and to assess the potential contribution of this technique for the diagnosis and prognostic evaluation of aortopathy in pathologies with alterations of the connective tissue such as Marfan syndrome and bicuspid aortic valve. Projects aim to identify markers of interest to detect a loss of elastic reserve of the aortic wall, at rest or under stress, whatever the diameter, in the presence of a genetic disease of the wall.
