Abstract
Endovascular aortic repair (EVAR) was first approved in Japan a decade ago, and approximately 10,000 EVAR procedures are performed annually.1) The short-term outcomes of EVAR in Japan were reported to be acceptable; however, several issues were revealed. Half of the cases violated the instructions for use, and a quarter of post-EVAR aneurysm sacs dilated by more than 5 mm in 5 years.2) In addition, new devices have emerged, generating a learning curve for their use. Therefore, updating the real-world EVAR data from Japan will serve as a database for physicians to refer to during preoperative sizing or when considering procedural steps. This report demonstrated the number of EVAR procedures and the mortality and complication rates in 2017 in Japan using data from the Japanese Committee for Stentgraft Management (JACSM) nationwide registry, which includes outcome data for nearly all stent grafts shipped to Japan.2,3)
