Endovascular treatment of a wide-neck renal artery bifurcation aneurysm.

Wide-neck renal artery aneurysms are difficult or impossible to treat endovascularly with Guglielmi detachable coils. The authors report a case of embolization of a wide-neck aneurysm of the right renal artery bifurcation with the combination of a TrisPan coil (neck-bridge device developed by Boston Scientific Target) and Guglielmi detachable coils. Complete occlusion of the aneurysm with preservation of the renal artery and its branches was shown with angiography performed after the procedure.
