Nurses used the predictive checklist to assess patients at 6 hours, 12 hours, 24 hours, and 48 hours postprocedural. For each assessment, items were scored as "positive" (1 point) or "negative" (0 point). A total score ≥4 points was defined as high risk, triggering immediate actions: (1) increased monitoring frequency (vital signs every 15 minutes, neurological assessment every 1 hour); (2) urgent cranial CT/MRI scan; (3) notification of the neurointerventional team within 10 minutes; (4) initiation of targeted interventions (e.g., blood pressure control, anti-edema therapy) as per protocol.

Patients received standard post-EVT care, including vital sign monitoring (every 15-30 minutes for the first 6 hours, then every 1-2 hours), neurological assessment (every 4 hours), and routine laboratory and imaging examinations (e.g., cranial CT at 24 hours postprocedural). Nurses documented clinical findings in electronic medical records and notified physicians only when obvious abnormalities were detected (e.g., NIHSS score increase ≥4 points, severe hypertension).
