RESUMEN
OBJECTIVES: To describe a new technique based on a different deployment of the Endurant Stent-Graft System (Medtronic Cardiovascular, Santa Rosa, CA) during endovascular aortic aneurysm repair to guarantee a more precise deployment in presence of severe neck angulation (SNA). TECHNIQUE: The "step-by-step" deployment technique consists of an alternate partial release of the main body and of the free-flow suprarenal stents to approximate the radiopaque markers of the graft fabric to the aortic wall, obtaining a more precise delivery, reducing the possibility of downward dislodgments along the external curve of the infrarenal angle and asymmetrical deployments in presence of SNA. CONCLUSIONS: The "step-by-step" technique is a simple, safe, and effective graft-deployment method, which allows a very precise release in SNA and possibly achieves better results in the long-term period in such difficult anatomies.
