Open surgery of abdominal aortic aneurysms (AAA) is the reference treatment in a large number of cases. This is a heavy procedure performed in patients around 70 years of age.~In post-operative open aortic surgery, a stay in aftercare and rehabilitation is often necessary, especially in fragile patients.~The goal is to increase the patient's overall functional status to allow him to move away from the threshold below which he loses his independence for activities of daily living.~The pre-habilitation protocol includes 3 parts :~Oral nutrition ensures adequate caloric and protein intake to support muscle anabolism~Muscle building over a few sessions with a liberal physiotherapist to learn exercises and then independently~Cardio-respiratory endurance.~For the experimental group:~Initial visit with adaptive rehabilitation physician, 6-8 weeks prior to surgery:~Clinical examination with Wood classification - limits and restrictions.~Assessment of environmental resources~Definition pre-habilitation protocol and post-operative rehabilitation pathway~application of the ambulatory pre-approval protocol defined with the adaptive rehabilitation physician.~For the control group:~Support without pre-approval with application of other common practices of the service.~Follow up of both groups:~Post-operative follow-up visits with the surgeon (gathering the necessary information for comparative follow-up).~Mail-out of WHODAS 2.0, EQ-5D-5L and DIJON questionnaires at 3 and 6 months post-operative.
This is a pilot, prospective, randomized control trial that aim to provide a first estimation of the 3-month post-operative variation in the functional recovery of patients who benefited from an outpatient pre-habilitation program and patients who did not benefit from it.
