Progression of Perianeurysmal Inflammation after Endovascular Aneurysm Repair for Inflammatory Abdominal Aortic and Bilateral Common Iliac Artery Aneurysms

Clinical Outcomes After Endovascular Repair and Open Surgery to Treat Immunoglobulin G4–Related and Nonrelated Inflammatory Abdominal Aortic Aneurysms

“…Previous studies of the postoperative clinical course of IAAA treated by EVAR described that PAF remained unresolved or progressed in approximately half of the cases. 15–18 Similarly, in our report, PAF progression was detected in about half the IAAA cases treated by EVAR; most of these cases were EVAR IgG4+ with increased IgG4 in follow-up, but it was rarely seen in IgG4– cases.…”

“…Some surgeons have indicated that EVAR is a desirable alternative therapeutic strategy for IAAA, with reduced operative complication risks, 10–14 whereas other reports did not recommend EVAR for IAAA because of progressive postoperative PAF. 15–18…”
