The Nellix endovascular aneurysm sealing system (EVAS), licensed in Europe for treating infrarenal abdominal aortic aneurysms, has distinctive design comprising two balloon-expandable endoframes, each surrounded by a polymer-filled endobag. This review describes the current role of CT in both Nellix follow-up and pre-procedure planning, with reference to the inclusion criteria for Nellix insertion and the deployment technique. Knowledge of the expected evolution of CT features following Nellix insertion is important for recognizing potential complications. Examples of normal post-operative CT appearance, as well as complications seen to date are discussed.
