Stent-assisted coil embolization of a symptomatic renal artery aneurysm at a bifurcation point

Abstract Purpose Symptomatic renal artery aneurysms at bifurcation points present challenging clinical scenarios rarely amenable to endovascular repair due to concerns regarding parenchymal loss following intervention. Herein, we add to the scant body of literature describing successful endovascular repair of a saccular, symptomatic renal artery aneurysm situated at a bifurcation point. Methods A 52 year-old woman with a 2.5 cm extra-parenchymal, saccular, symptomatic left renal artery aneurysm underwent self-expanding stent-assisted detachable platinum microcoil embolization. Results Complete aneurysm exclusion was achieved with minimal parenchymal loss. There were no perioperative complications and no evidence of acute kidney injury peri-operatively or at three months follow-up. Sustained symptomatic relief was achieved. Conclusion Endovascular therapy can provide safe and effective aneurysm treatment within challenging bifurcated renal artery anatomy.
