Endoleaks after endovascular abdominal aortic aneurysm repair: management strategies according to CT findings

With increasing use of endovascular techniques for repair of abdominal aortic aneurysms, the prevalence of leakage into excluded aneurysm sacs (endoleaks) as a complication has risen. We will describe and illustrate the imaging findings for endoleaks involving abdominal aortic aneurysms. We will also discuss which types of endoleaks require urgent catheter-based evaluation. Radiologists should be familiar with the classification scheme for endoleaks and understand which types of endoleaks require urgent catheter-based evaluation.
