The Vessel Navigator (VN) developed by Philips allows the use of pre-acquired angio-scan or angio-MRI image by superimposing it (X-ray Fusion) on X-ray scopy to provide the arterial tracing (Fusion Roadmap).\n\nAn angio-MRI (Philips 3 Tesla MRI) imaging of the aortic arch will be first performed (as part of preoperative assessment or systematic follow-up of aneurysms or arteriovenous malformations). A first operator will perform the arteriography under the usual conditions without using the VN.
