Background:
We describe the treatment of a renal artery aneurysm with complex anatomy using coils and the PipelineTM Embolization Device (Medtronic, Irvine, CA), a flow-diverting stent typically used for the treatment of intracranial aneurysms.
Methods:
A 62-year-old female with history of an asymptomatic right renal artery aneurysm that was discovered incidentally 10 years ago was found to have enlargement of the aneurysm (1.9cm to 2.7cm) on a repeat surveillance CT scan. She was successfully treated with combined Pipeline Embolization Device and coil embolization of the aneurysm sac.
Results:
Post-procedural angiography showed complete occlusion of the aneurysm with maintenance of perfusion to the entire kidney.
Conclusion:
PipelineTM assisted coil embolization may be an option for parenchyma-sparing treatment of renal artery aneurysms with complex anatomy.
