This article provides a narrative review of the current literature and our expert opinion concerning the iliac branch endoprosthesis (IBE) and its use in the treatment of complex abdominal aortic aneurysm (AAA) cases with concomitant aneurysmal involvement of the common iliac artery (CIA) and/or the internal iliac artery (IIA). Up to 25% of those with an AAA may present with extension of the aneurysmal disease into the iliac vessels. This anatomy may complicate the standard endovascular aortic repair (EVAR) procedure, as the available length of distal landing zones is altered. The optimum treatment requires both the adequate sealing of the distal landing zone as well as the preservation of the pelvic circulation through the IIA. Extensive preoperative assessment of the anatomy, as well as an accurate deployment following all procedural steps, enables endovascular treatment of complex aorto-iliac aneurysms safe with excellent midterm clinical outcomes. The current literature shows that the utilization of the IBE offers a durable treatment of these complicated cases with results equal to those of the open repair, without the associated morbidity. Preservation of the pelvic circulation is recommended to prevent pelvic ischaemic symptoms and can also be carried out on both sides provided certain anatomical requirements are met.
