Aneurysmal or occlusive abdominal aortic pathology has seen its prevalence increase over the years despite the various cardiovascular risk factor management campaigns deployed.

Currently, a large proportion of these aortic pathologies require effective and definitive treatment by open surgery. In fact, minimally invasive endovascular treatment, which can provide good results in certain cases, cannot be generalized simply and can even lead to sometimes incomplete treatments requiring even more complex secondary open surgery.

The preoperative assessment before open aortic surgery is relatively well coded with cardiological and respiratory assessments in particular. However, the literature has so far never focused on the overall vision of the patient with a complete functional assessment which would make it possible to consider a specific preoperative fragility scale and would thus give practitioners corrective targets before such an intervention. in order to simplify the patient's post-operative journey by limiting complications.

The investigators therefore propose to collect a certain number of elements already collected in standard care in a systematic and prospective manner in order to create a risk scale. All of these elements being modifiable, they should ultimately make patients more robust for such an intervention.
