Abstract
Endovascular aortic aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysms. Successful endovascular exclusion of abdominal aortic aneurysms is dependent on formation of a seal between the endoprosthesis and the nonaneurysmal aorta. Recommendations for suitability of EVAR have focused on preoperative anatomic characteristics of the proximal landing zone such as the length of the neck and angulation. Type I and III endoleaks require prompt, definitive repair or explantation. In addition, occlusion of the renal artery during the procedure or follow up period may affect the prognosis of the patients. However, the presence of the transrenal stent struts could make access to the renal artery for secondary intervention difficult or impossible. We review and report our experience of endovascular management of type I endoleaks and renal artery occlusion during the EVAR procedure and follow-up period.
