Post-Implantation Syndrome and Laboratory Markers Following EVAR and TEVAR

This intervention involves EVAR or TEVAR for the treatment of abdominal or thoracic aortic aneurysms, respectively. The procedures were performed using commercially available stent-grafts via a transfemoral approach under standard perioperative protocols. The study specifically focuses on the systemic inflammatory response following these interventions, with close monitoring of laboratory parameters including IL-6, neutrophil-to-lymphocyte ratio (NLR), CRP, leukocyte count, and procalcitonin during the early postoperative period. No adjunctive anti-inflammatory or immunomodulatory therapies were administered.
