Post-Implantation Syndrome. The impact of different devices for endovascular abdominal aortic aneurysm repair and related etiopathogenetic implications
Postimplantation syndrome (PIS) is a systemic inflammatory response occurring in early phase after abdominal aortic aneurysm (AAA) endovascular repair (EVAR). PIS can also occur after endovascular aneurysm sealing (EVAS) with Nellix system which prevent new onset of mural thrombus inside. Aim was to compare the incidence of PIS after EVAS and EVAR in order to evaluate the possible role of the new-onset thrombus inside the aneurysmal sac.
