Use of Interventional Neuroradiology Devices (Solitaire AB and Cascade Net) In The Treatment of Complex Renal Aneurysms Through Stent-Assisted Coil Embolisation.

Introduction: The risk of rupture of true renal artery aneurysms is low but when they are bigger than 2 - 2.5 cm it increases significantly, making treatment essential. The need to use alternatives to conventional techniques in order to avoid predictable complications as coil migration is mandatory. Discussion: Routinely-used techniques in interventional neuroradiology such as flow diverters or those assisted with an occlusion balloon or stent have are suitable alternatives for complex aneurysms. Conclusion: Interventional neuroradiology devices such as the Cascade Net stent (Perflow Medical and Grupo Logsa) and Solitaire AB stent retriever (Medtronic) are valid and safe options. We describe the technique of such devices.
