Post-Implantation Syndrome: the impact of different devices for endovascular abdominal aortic aneurysm repair and related etiopathogenetic implications.

CONCLUSIONS: The etiology and pathophysiology of 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. In this study, PIS was significantly less frequent after EVAS than EVAR. The lower inflammatory reaction observed after EVAS might be related to the endobags of Nellix system which completely seal the aneurysm sac reducing the new onset of mural thrombus. This could confirm the role of new-onset mural thrombus in the genesis of PIS. The systemic inflammatory response does not significantly differ after endoskeleton AFX device deployment compared with other EVAR exoskeleton stent grafts. PIS does not seem to have any significant prognostic implications in terms of major adverse events. PMID: 32401471 [PubMed - as supplied by publisher]
