Decellularized aortic allograft stabilized by an absorbable magnesium scaffold for substitution of the descending aorta

Introduction: Several pathologies of the thoracic aorta such as blunt chest traumas, aortic aneurysms/ dissections require surgical treatment and are associated with a high risk of rupture and organ ischemia. Aside from endovascular aortic repair, often invasive treatment is unavoidable. Widely used dacron prostheses have many limitations such as the inability to grow, repair and remodel as well as the predisposition for infections, risk of thrombosis and lack of windpipe function. Here, we report the successful stabilization of decellularized aortic allografts with an absorbable magnesium scaffold (AMS) in descending aorta position.
