Higher serum occludin after successful reperfusion Is associated with early neurological deterioration

Aims Early neurological deterioration (END) is an important factor that affects prognosis in patients with acute ischemic stroke. We explored the relationship between serum occludin levels after successful reperfusion and END in patients treated with endovascular thrombectomy (EVT). Methods We prospectively enrolled 120 stroke patients who underwent EVT with successful reperfusion. Enzyme‐linked immunosorbent assay was used to detect the serum occludin levels on admission and within 1 h after successful reperfusion. Receiver operating characteristic curves (ROC) and regression analysis were used to compare the relationship between serum occludin and END after thrombectomy. Results Among the 120 patients, 36 (30%) experienced END. The END group had higher serum occludin levels than the non‐END group after successful reperfusion [4.31 (3.71–5.38) vs 6.32 (5.88–6.99), p
