Current Status of Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm

Abstract

The indications for endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) have expanded significantly. Recently, 2020 guideline on diagnosis and treatment of aortic aneurysm and aortic dissection was published in Japan. Furthermore, treatment outcomes of EVAR in Japan using big data from the Japanese Committee for Stentgraft Management (JACSM) have been reported. While good short-term results have been reported in Japan, long-term results in Europe and the United States have revealed that open surgical repair is superior to EVAR. Although advances in technology and devices are expected to improve the long-term results of EVAR and further expand its indications for AAA, open surgical repair should be selected in appropriate cases based on considering the anatomical characteristics and surgical risks of individual patients.
