ABSTRACT
Introduction: Despite improvements in endograft design, operator skills, and patient selection, late endovascular abdominal aortic aneurysm repair (EVAR) associated complications and need for reinterventions remains the Achilles heel. These complications erode the early benefit over open aneurysm repair during long-term follow-up. The recently introduced endovascular aneurysm sealing (EVAS) is an innovative technology with the intention to lower these EVAR related complications.
Areas covered: In this review the EVAS technique, indications, and possible applications, will be discussed, as well as a critical appraisal of clinical outcomes.
Expertcommentary: EVAS is a promising technique for treating abdominal aortic aneurysms, and early efficacy data are encouraging in very suitable straight forward anatomy. The Nellix device is still in development. Longterm results are awaited.
