EVAR後の腹部大動脈瘤に対する開腹アプローチ

抄録

A total of 831 patients underwent EVAR for AAA between April, 2007 and October, 2018. Of these, late open reintervention for aneurysmal sac enlargement after EVAR was performed for 22 patients. All of them were discharged home with no significant complications during the hospitalization. Intraoperative findings at the time of exposing the aneurysmal cavity included various and multiple endoleaks, which could not be identified by enhanced CT. A variety of persistent endoleaks were considered to be one of the primary factors which could exacerbate clinical outcomes of additional endovascular treatments for sac enlargement after EVAR.
