WAJNBERG, Eduardo; AQUINO, Diogo  e  SPILBERG, Gabriela. A preliminary experiment utilizing "aneurysm neck remodeling technique" for management of complex wide-necked renal artery aneurysms. Radiol Bras [online]. 2010, vol.43, n.1, pp.29-33. ISSN 0100-3984.  http://dx.doi.org/10.1590/S0100-39842010000100009.

OBJECTIVE: To report preliminary results of aneurysm neck remodeling in the management of wide-necked renal artery aneurysms. MATERIALS AND METHODS: Five patients (three women and two men between 49-72 years; mean age, 62 years) with wide-necked renal artery aneurysms measuring from 10 to 25 mm in diameter were submitted to balloon-assisted coil embolization along a three-year period. The micro-balloon was placed along the aneurysm neck and temporarily inflated for introduction of detachable microcoils into the aneurysmal sac. RESULTS: Balloon positioning and microcoil embolization were successfully completed in all of the cases with achievement of complete aneurysm occlusion without coil protrusion or parent vessel obstruction. CONCLUSION: The present preliminary experiment indicates that the "aneurysm neck remodeling" is technically feasible and effective in the management of complex renal artery aneurysms without sacrificing any arterial branch.
