Interventional neuroradiology, also called surgical neuroangiography or endovascular neurosurgery, is an evolving subspecialty area wherein practitioners utilize transvascular catheter interventions to treat a variety of vascular lesions involving the brain and spinal cord. Originally developed primarily in an adjunctive role to conventional surgical therapy, these techniques are gaining increased acceptance as complementary, and in some cases preferred therapy for intracranial aneurysms, carotid cavernous fistulae (CCFs), arteriovenous malformations (AVMs) and dural arteriovenous fistulae (DAVF). Endovascular stroke therapy continues to evolve, as does tumor embolotherapy and the treatment of vasospasm following subarachnoid hemorrhage. Improved clinical outcomes are due in part to concurrent technological advances, such as new embolic agents and smaller, softer, and more maneuverable microcatheters.1,2 The rapid growth of endovascular techniques has given rise to a new subspecialty, with practitioners coming from the ranks of both neuroradiology and neurosurgery. These are complex and demanding procedures, and are often coordinated by teams of specialists from neurology, neurosurgery, and neuroradiology. This chapter will review the current status of interventional techniques in some of their more common CNS applications. This is by no means a comprehensive review, and due to rapid advances in this area portions of this discussion may soon be obsolete. Nonetheless, it is hoped that this introduction will serve as an informative overview of this exciting and fascinating medical subspecialty.
