Interventional Neuroradiology: A Review

Abstract

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.

Multimodal MRI diagnosis and transvenous embolization of a basicranial emissary vein dural arteriovenous fistula: A case report

“…However, DSA has ionizing radiation and cannot be used to observe changes in brain structure. 8 , 14 Multimodal MRI has allowed for the evaluation of DAVFs, without ionizing radiation and invasion. 15 TOF-MRA without saturation, due to its high spatial resolution, is important for diagnosing and identifying the feeding artery, fistula location, and venous drainage.…”

Current Scientific Evidence Regarding Use of Carotid Stenting and Endarterectomy

“…A recent review by Pelz et al has provided an excellent opportunity to clarify the current scientific evidence regarding the role of carotid endarterectomy and stenting in clinical practice. 1 First, in the prevention of arterial disease complications, medical intervention (lifestyle coaching and appropriate medication) is the basis and very effective. Medical intervention is non-invasive and protects the whole arterial tree.…”
