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

Purpose: To compare the follow-up results of endovascular aneurysm repair (EVAR) vs open surgery (OS) for inflammatory abdominal aortic aneurysms (IAAAs) with regard to immunoglobulin G4–related diseases (IgG4-RD), which are fibrous inflammatory conditions characterized by elevated serum IgG4 concentrations and numerous infiltrations of IgG4+ plasmacytes. Methods: Between January 2005 and December 2015, 91 patients were treated with EVAR (begun...
