Visualization of Distal Vessels during Mechanical Thrombectomy using Aortic Cone-beam Computed Tomography

Neurologia Medico-Chirurgica
During mechanical thrombectomy, manipulation under the limited visibility of vessels distal to the occlusion site could result in vessel perforation. Standard imaging techniques such as magnetic resonance imaging and digital subtraction angiography often
