ABSTRACT
Since 2000 Dorros et al. reported the first case of type A aortic dissection (TAAD) treated with an endovascular repair, surgeons explored a novel treatment option for TAAD gradually. The application of endovascular repair for TAAD highlights some points below which should pay attention to because of the special anatomic location and morphological characteristics of ascending aorta: (1) customized treatment strategy based on the characteristics of patients; (2) pre-operation evaluation; (3) selection of the stent and delivery system; (4) selection of the access sites; (5) preservation of the coronary artery flow, aortic valve function and perfusion of the branch vessels; (6) accurate location of stent-graft; (7) mid-term and long-term follow-up. In a word, it's helpful to avoid misunderstanding in treatment and improve the safety of operation by grasping the indication and the technical points and making the customized treatment strategy based on the characteristics of patients.
