Clinical career

Dr. Vitor Mendes Pereira is a neurosurgeon specialized in minimally invasive procedures of the intracranial and spinal circulation and percutaneous spinal interventions for pain management. He is a Professor of Medical Imaging and Surgery at the University of Toronto and Staff Physician at the Toronto Western Hospital and Hospital for the Sick Children. He did his residency in Sao Paulo, Brazil and his clinical fellowship in France (CHU Bicetre and Rothschild Foundation). Dr Pereira has worked as the Head of Interventional Neuroradiology division and Privat-Docent at the University Hospital of Geneva, Switzerland from 2008 to 2014.

He is interested in the treatment of complex neurovascular diseases including curative treatment of arteriovenous malformations, dural malformations, large and giant aneurysms, spinal vascular disorders and pediatric vascular malformations. Amongst his clinical achievements, he was one of the pioneers of the use of stent retrievers in acute stroke and as one of the largest experiences with flow diverters world-wide. He has also performed multiple world-first cases using the most innovative devices in our field including SQUID (liquid embolic for AVM treatment), Pipeline Flex, and Surpass EVOLVE device for aneurysm treatment. He has described many techniques for AVM and dural fistula treatment and he has one of the largest transvenous and curative endovascular AVM treatment series internationally. In terms of more recent achievements, he has performed the world’s first robotic neurovascular intervention and he is committed to develop remote stroke and aneurysm treatments in the future.

He is leading clinical and basic research on arteriovenous malformations, brain aneurysms and stroke. He was/is the principal investigator in multiple global and multicenter studies including STAR trial, SWIFT-PRIME study, SWIFT DIRECT trial, MAXPIPE study, CARO trial and EVOLVE study.

Dr Pereira is very engaged on advanced training and education in the field of interventional neuroradiology and endovascular neurosurgery. He runs or participates in several courses and workshops worldwide, teaching cerebral and spinal vascular anatomy, natural history, imaging and advanced treatment of neurovascular diseases. He is an active member of several medical societies, and he has also contributed over 260 publications to his field on various aspects of neurosciences. He is the lead scientist and principal investigator of the RADIS lab.
