ABSTRACT
The success of endovascular aneurysm repair (EVR) largely depends on an accurate preopera-
tive assessment of aneurysm morphology. The use of EVR in patients considered anatomically
unsuitable increases the risk for adverse outcome, including endoleak, stent migration and
aneurysm rupture (1). Several imaging modalities have been proposed to facilitate the
preoperative assessment of aortic morphology. The ideal modality should be noninvasive and
still provide all information needed for EVR. This includes information on the dimensions and
quality of the arterial access site, aneurysm and proximal and distal seal zones (2).
