Abstract
Endovascular repair using stent-grafts for abdominal aortic aneurysms (AAAs) is becoming increasingly employed worldwide. Imaging has great importance in the assessment of AAAs and in decision-making.
Spiral-computed tomography (CT) is valuable in patient selection, morphologic assessment and follow-up. Recent improvements in technology (multislice CT) and in image processing (three-dimensional processing
software, CT simulation before stent-grafting) allow an opportunity to replace X-ray angiography in the
assessment of AAAs. Magnetic resonance imaging is becoming a favoured method, as it can be used without iodinated contrast agents; however, there are often
limitations in the availability of equipment. Doppler ultrasound is the safest imaging method, but gives
variable results and cannot be used alone. This article provides information and recommendations about the use of imaging techniques before and after
endovascular repair of AAAs.
