Post-Implantation Syndrome and Laboratory Markers Following EVAR and TEVAR

The aim of this observational study is to investigate the relationship between postimplantation syndrome (PIS) and laboratory inflammatory parameters following endovascular aortic repair (EVAR/TEVAR). PIS is a systemic inflammatory response that may occur after EVAR or TEVAR and lacks a standardized clinical definition. This study seeks to determine whether specific laboratory biomarkers-particularly white blood cell count, C-reactive protein (CRP), interleukin levels, and neutrophil-to-lymphocyte ratio (NLR)-can serve as reliable indicators for the diagnosis and assessment of PIS.
