Incidence of post-implantation syndrome with different endovascular aortic aneurysm repair modalities and devices and related etiopathogenetic implications

Postimplantation syndrome (PIS) is a systemic inflammatory response occurring in an early phase after abdominal aortic aneurysm (AAA) endovascular repair (EVAR). The pathophysiology underlying PIS is not yet well understood. It is speculated that the type of the stent graft or the mural thrombus within the AAA may play a role in determing this inflammatory response. At present, there is no consensus about the influence of PIS on clinical outcomes during follow-up. The endovascular aneurysm sealing (EVAS) with the Nellix sac-anchoring endoprosthesis (Nellix Endovascular, Palo Alto, Calif) is a novel modality for AAA repair which obliterates the sac thus preventing the new onset of thrombus in the aneurysm sac.
