Complex abdominal aortic aneurysms (AAA) include those that originate close to or above the renal arteries, and those with an underlying inflammatory or infective cause. Occasionally, aneurysms can be complicated by involvement of adjacent structures or by pre-existing anatomical variants. Open surgery in experienced hands has been shown to be safe, but can have worse outcomes than for repair of uncomplicated infrarenal aneurysms. Endovascular solutions offer a less invasive approach. There are, however, limitations to the application of this technology. Evidence does support the supposition that complex endovascular repair is at least as good and probably better in terms of perioperative risk than open repair, but entails a requirement for life-long surveillance and reintervention. This chapter will outline the technical aspects of managing complex AAAs and associated conditions.
