Flow-diverting stents (FDS) are sophisticated endovascular devices that aim to modulate blood flow and promote aneurysm thrombosis while maintaining branch vessel patency. Initially designed and developed for the treatment of intracranial aneurysms, these devices have since been applied to the peripheral circulation. However, they are still used sporadically, largely due to a lack of the scientific evidence supporting its use in visceral aneurysms. This review article aims to provide an overview of the current data on the clinical outcomes from the use of FDS in the treatment of complex visceral and renal aneurysms or pseudoaneurysms and to assess the added value of these devices.
