Intracranial carotid artery aneurysm treatment: First reported case of derivo®flow-diverter placement by direct carotid artery puncture

Brain health may be threatened by aneurysm ruptures, and early recognition of these vascular malformations allows for neuroradiological intervention. Neurointerventional procedures are usually performed with femoral artery access. In patients with severe anatomical complexity of the supra-aortic vessels, however, treatment by this approach could be hindered or impossible. Flow-diverter stent deployment is an effective and safe treatment for large, wide necked intracranial aneurysms, but it requires a complete and firm stability of the coaxial system to achieve a correct and precise deployment of the device. We present the first reported Italian case of a patient with an intracranial aneurysm which was treated with Flow-diverter stent (DERIVO®; AcandisGmbH & Co. KG; Pforzheim; Germany) by direct common carotid artery puncture due to severe tortuosity of supra-aortic trunks.
