The Evolution of Anesthesia for Neuroradiologic Procedures

The volume and range of procedures undertaken by interventional neuroradiologists continues to expand. They are now treating many conditions previously considered untreatable or only amenable to open surgical techniques. To facilitate the close cooperation required between radiologists and anaesthetists necessary for the successful outcome of these complex and lengthy procedures, it is important for the anaesthetist to have an appreciation of the pathophysiology, potential multisystem effects of the underlying disease, cerebral protection strategies and the potential pitfalls of each procedural technique. Maintaining vigilance during the post-procedural monitoring phase is essential for the early recognition of potential complications, such as bleeding or vessel occlusion, which may warrant further emergency radiological or neurosurgical interventions.
