Early onset of periaortic inflammation after EVAR with inferior vena cava involvement: a case report

Endovascular treatment of abdominal aortic aneurysm (EVAR) represents a good alternative to open surgery, also in patients who present inflammatory abdominal aortic aneurysm, resulting in reduction of the inflammatory process in many cases. Instead, the onset of periaortic inflammation after EVAR is a rare event with an unclear pathogenesis, time of onset, and clinical presentation. This is a case report of a very early onset of periaortitis after EVAR with inferior vena cava involvement and stretching, resulting in lower limb swelling and back pain, treated by corticosteroid drug with a good remission of the pathology.
