Contrast-induced neurotoxicity (CIN) is an adverse reaction to contrast agents which can occur in the context of diagnostic and therapeutic neurological endovascular procedures. Our goal was to conduct a systematic review of patients reported in the literature diagnosed with CIN after neurological endovascular procedures. A systematic search of EMBASE and MEDLINE databases was conducted. Inclusion criteria were age ≥ 18 years; neurological endovascular procedure performed ≤ 24 h before ictus; new manifestations compatible with encephalic dysfunction; imaging performed < 7 days after ictus; exclusion of other causes and manifestations attributed to pre-existing conditions. Forty-eight patients were included, of which 60.4% were female and 60.4% had arterial hypertension; median age was 63 years. The most frequent procedure was diagnostic cerebral angiography ( n = 24, 50.0%) and non-ionic contrast agents were more frequently used ( n = 40, 83.3%). Twenty-six patients (54.2%) developed clinical manifestations compatible with CIN during or immediately after the procedure, and the most frequent manifestations were encephalopathy, cortical blindness and motor deficit. The most frequent imaging findings were cortical contrast enhancement on CT ( n = 23/42), and cortical sulci effacement ( n = 18/48). Most patients presented complete clinical recovery (89.6%) at a median time of 3 days. Among patients with neuroimaging changes who underwent follow-up, complete regression of the abnormalities was shown in 81.5% at a median time of 5 days. CIN is a rare adverse reaction in the context of neurological endovascular procedures. Recognition of clinical manifestations and typical imaging abnormalities, while excluding other causes, is essential for diagnosis.
