Endoleaks After Endovascular Abdominal Aortic Aneurysm Repair: Management Strategies According to CT Findings

OBJECTIVE. 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. CONCLUSION. Radiologists should be familiar with the classification scheme for endoleaks and understand which types of endoleaks require urgent catheter-based evaluation.
