Abstract

Abstract: Late open conversion (LOC) after endovascular aneurysm repair (EVAR) is associated with high morbidity and mortality. Standard surgical technique of LOC has not been established. This report presents a rapid aneurysmal formation in the unreplaced infrarenal aorta after LOC with complete endograft explantation without suprarenal fixations. A 76-year-old man presented with a left common iliac artery aneurysm (CIAA), for which he underwent EVAR to embolize the left internal iliac artery. Although his aneurysmal sac size initially showed a reduction, computed tomography at the 3-year interval post-EVAR demonstrated an increased sac size. Thus, he underwent open aortic repair of the CIAA. Though the postoperative course was uneventful, the size of the unreplaced infrarenal aorta showed a significant increase one year after open conversion. Reoperation was performed, but vascular prosthesis infection occurred as a complication and the patient died on the 196th postoperative day.
