Prognostic Accuracy of N20 Somatosensory Potential in Patients With Acute Ischemic Stroke and Endovascular Thrombectomy

BACKGROUND Somatosensory evoked potentials may add substantial prognostic value in patients with acute ischemic stroke and contribute to the selection of who benefit from revascularization therapies beyond accepted therapeutic time windows. We aimed study accuracy N20 somatosensory potential component hemisphere anterior large‐vessel occlusion undergoing endovascular thrombectomy (EVT). METHODS Presence amplitude response were recorded before after EVT. Its adjusted predictive for functional independence (modified Rankin scale score, ≤2) at day 7 was analyzed by binary logistic regression adjusting age, mean arterial blood pressure, National Institute Health Stroke Scale, Alberta Program Early CT Score, serum glucose. power compared that clinical imaging models using receiver operating characteristics curve analysis. RESULTS A total 223 consecutive studied (mean 70 years; median Scale 18). recordings identified presence 110 (49.3%), absence 58 (26%), not assessable 55 due radiofrequency interferences angiography room. Before EVT, predicted a sensitivity 93% (95% CI, 78%–98%) negative 80%–98%). The odds ratio 9.9 3.1–44.6). In analysis, showed higher area under than prehospital or in‐hospital variables, including advanced imaging. Sensitivity increased 100% 0.85–1) when present CONCLUSION monitoring is noninvasive bedside technique could help eligibility EVT predict recovery.
