Endovascular Aneurysm Repair (EVAR) has become an important treatment method for abdominal aortic aneurysms due to its advantages of shorter operative time, faster postoperative recovery, and lower early postoperative mortality. However, the incidence of complications and the postoperative reintervention rates are higher than those of open surgery. The main complications after EVAR include access vessel injury, post-implantation syndrome, stent migration, endoleaks, visceral branch artery occlusion, lower limb ischemia, and stent infection, which are also the primary causes of reintervention. In recent years, the causes and associated risk factors of various postoperative complications of EVAR have attracted widespread attention and discussion, which are of great significance for improving surgical techniques, enhancing postoperative monitoring, and improving patient outcomes. This paper provides a review of the current complications, associated risk factors, and management strategies after EVAR.
