Abstract

Background: Graft disruption is an unusual complication of the endovascular abdominal aortic aneurysm repair (EVAR).

Case presentation: A 71-year-old man underwent standard EVAR with Zenith Alpha Abdominal endograft. Follow-up examinations revealed an initial significant sac shrinkage. At 24 months, duplex ultrasound (DUS) scan and computed tomography showed increase of the sac diameter associated with complete disconnection of the suprarenal stent-graft from the main body without evidence of endoleak. A standard relining with a thoracic endograft was performed between the suprarenal stent and the main body of the previous graft. At 6 months DUS revealed sac shrinkage.

Conclusions: This report demonstrates an uncommon cause of endograft failure with suprarenal stent disconnection from main body and highlights the need for continuous follow-up in patients undergoing EVAR.

Keywords: Abdominal aortic aneurysm; Device design; Endoleak; Endovascular aneurysm repair; Endovascular treatment/therapy.
