Endovascular repair of a complex renal artery aneurysm using PipelineTM Embolization Device (PED) assisted coil embolization

J Radiol Case Rep. 2021 Oct 1;15(10):1-9. doi: 10.3941/jrcr.v15i10.4156. eCollection 2021 Oct.

Abstract

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.
