a new deficit significantly increased as a function of the magnitude of IONM change and type of complication (table 2). For procedures with changes associated with a perioperative complication (n=83), the rate of new neurologic deficit was 60% if the change remained unresolved (n=18/30). However, the rate and risk of new deficit was significantly decreased if a change was partially resolved (28.6%, n=6/21, OR=0.27), and was dramatically decreased if fully resolved (3.1%, n=1/ 32, OR=0.02) (figure 1). Conclusions IONM has excellent diagnostic accuracy during cerebral neuroendovascular procedures. Both the magnitude and putative cause of IONM change provide diagnostic and prognostic information. Perioperative complications are significantly less likely to result in postoperative dysfunction if there is a timely diagnosis and intervention that results in the resolution of IONM signal change.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
