Interventional Neuroradiology: A Review

Can J Neurol Sci. 2021 Mar;48(2):172-188. doi: 10.1017/cjn.2020.153. Epub 2020 Jul 16.


Interventional neuroradiology (INR) has evolved from a hybrid mixture of daring radiologists and iconoclastic neurosurgeons into a multidisciplinary specialty, which has become indispensable for cerebrovascular and neurological centers worldwide. This manuscript traces the origins of INR and describes its evolution to the present day. The focus will be on cerebrovascular disorders including aneurysms, stroke, brain arteriovenous malformations, dural arteriovenous fistulae, and atherosclerotic disease, both intra- and extracranial. Also discussed are cerebral vasospasm, venolymphatic malformations of the head and neck, tumor embolization, idiopathic intracranial hypertension, inferior petrosal venous sinus sampling for Cushing's disease, and spinal interventions. Pediatric INR has not been included and deserves a separate, dedicated review.

Keywords: Arteriovenous malformations; Cerebral aneurysms; Cerebrovascular atherosclerosis; Interventional Neuroradiology; Spinal intervention; Stroke.
