recruitment difficulties

Open surgery for aneurysmal aortic disease can lead to cardiac, renal, pulmonary or muscular complications, essentially due to the aortic clamping. Ischemic preconditioning can be useful in order to decrease these complications. The investigators would like to use an ischemic preconditioning protocol during open surgery of aortic aneurysm in order to decrease these complications.
