Late Conversion After Sac Anchoring Endoprosthesis for Secondary Aortic Aneurysm Infection.

Purpose: To demonstrate explantation of the Nellix Endovascular Aneurysm Sealing (EVAS) System in the setting of infection. Case Reports: Two male patients, 71 and 83 years old, underwent Nellix implantation for asymptomatic infrarenal aortic aneurysms measuring 5.1 and 6.3 cm, respectively. Each developed late infections at 8 and 4 months post EVAS, respectively. The first patient experienced aneurysm rupture after medical therapy failed; the Nellix endosystem was explanted in an uneventful procedure. The second patient developed an aortoduodenal fistula, which was sutured before the Nellix device was removed without complications. The patient died 3 months later, presumably due to ongoing infection. Conclusion: The need to explant a Nellix EVAS System due to graft infection is a straightforward procedure compared to the removal of a conventional endograft with suprarenal fixation. It requires only temporary suprarenal clamping. The devices can be easily removed due to the lack of penetrating components ...
