Abstract Since the advent of endovascular aortic repair (EVAR) nearly three decades ago, there has been a paradigm shift in the treatment of the abdominal aortic aneurysm (AAA) to favor EVAR due to its reduced operative mortality, less invasive nature, and faster Keywords recovery times. However, more recently there has been an accumulation of data from ► abdominal aortic large meta-analyses and randomized clinical trials revealing that EVAR has no survival aneurysm benefit after approximately 2 years and is associated with substantially higher rates of ► open aortic surgery reintervention and aneurysm rupture in the long term. These findings call into question ► aortic repair the durability of EVAR compared with open aortic repair and emphasize the need for ► endovascular aortic surgeons to remain competent with open aortic surgery in the modern era. This article repair will provide comprehensive review of a large body of literature comparing endovas- ►
