Abstract    Endovascular aortic repair （EVAR） has gradually become the mainstream treatment of abdominal aortic aneurysm （AAA）. However，EVAR requires sufficient landing zone both in the proximal and distal region of aortic aneurysm. The premise and the key for EVAR is to preserve the main branches of the abdominal aorta. Recently，with the advancement of fenestrated and branched endograft and the adoption of chimney technique，sandwich technique and hybrid technique，the indication of EVAR for AAA is expanding. Patients who present with suprarenal AAA，complex aorto-iliac aneurysm，or have the contraindication for open surgery repair，gradually got the chance to the endovascular technologies and benefit from them. Each technology has its own characteristics and scope. According to the guideline of preservation of the main branches in EVAR，surgeons should make their decision based on the specific characteristics of lesions，their experience，indication and limitations of different technologies，with the purpose of improving the long term prognosis.
