Periaortic inflammation after endovascular aneurysm repair.

BACKGROUND

The periaortitis seen with inflammatory abdominal aortic aneurysms usually resolves after repair by both open and endovascular techniques. Conversely, the de novo development of retroperitoneal fibrosis after endovascular aneurysm repair (EVAR) has also been rarely described, and we present a case and also review the literature.

METHODS AND

RESULTS

A 63-year-old man underwent EVAR for an asymptomatic, noninflammatory abdominal aortic aneurysm, presenting 9 months subsequently with left loin pain, raised inflammatory markers, and radiological evidence of periaortic inflammation causing significant left ureteric obstruction. Ureteric stenting resolved the hydronephrosis, and the periaortitis improved with combination of steroid and tamoxifen therapy.

CONCLUSION

Periaortitis causing renal impairment after EVAR is a rare complication. Prompt recognition and ureteric stenting helps to prevent long-term renal damage. Steroid and tamoxifen therapy is recommended to treat and avoid recurrence of periaortitis.
