Treatment of a Juxtarenal Aneurysm with a Parallel Graft in the Left Renal Artery and Polymer-Based Technology to Seal the Entire Aneurysmal Sac.

ABSTRACT

BACKGROUND: Presenting the treatment of a juxtarenal aneurysm using a Nellix device combined with a chimney stent in a renal artery. CASE REPORT A 72-year-old woman was diagnosed with a 5.5-cm bilobed juxtarenal aneurysm. She underwent successful aneurysm repair with the Nellix system combined with a chimney stent in the left renal artery. Angio computed tomography control showed complete sealing of the aneurysm sac and patent chimney stent. CONCLUSIONS: Endovascular aneurysm sealing combined with chimney may be a valid way to treat juxtarenal aneurysms, and the conformable polymer-filled endobags may provide a durable seal around the chimney-graft preventing gutter formation.
