The experiment aims at reproducing an aortic dissection. This pathological condition starts from a tear in the inner aortic wall, that causes the blood to flow between the layers of the aortic wall. We created an ex-vivo aortic dissection model by suturing two pig aorta and we made three tears between true and false lumen. The model was connected to the hydraulic circuit to get the pressures in both true and false lumen.
