Endovascular treatment of a wide-necked renal artery aneurysm with a flow diverter stent

Renal artery aneurysm (RAA) is a rare, often asymptomatic disease (0.1% incidence in general population) and can be incidentally diagnosed during an abdominal imaging workup. The traditional, gold standard of treatment is open surgery, carrying with it, however, a high risk of nephrectomy, mortality, and collateral morbidity. The endovascular approach is currently the most valid alternative to treating RAAs reducing, as it does, the risks associated with the surgical approach/open surgery. Herein we report on our experience with a case of wide-necked RAA treated with the Pipeline Vantage (Medtronic) flow diverter stent. Wide-neck aneurysms are defined as having neck diameters greater than 4 mm. Our choice of endovascular treatment was preferred over the surgical option notwithstanding the large size of the neck and the involvement of the branching vessels.
