- Abstract
Objective: This study evaluates reocclusion prognostic outcomes and explores reocclusion risk factors after mechanical thrombectomy (MT) in Chinese stroke patients. Methods: Altogether, 614 patients with AIS with successful recanalization after MT were recruited in this study and divided into the reocclusion and the non‐reocclusion group depending on the 24‐h imaging results after MT. Differences between the two groups were compared including 24‐h and 7‐day National Institutes of Health Stroke Scale (NIHSS) scores, 90‐day modified Rankin scale(mRS) scores, good prognosis (mRS:0–2) rates, incidence of intracranial hemorrhage, and 90‐day mortality. Results: Forty‐four (7.2%) patients experienced reocclusion within 24 h. Compared with the non‐reocclusion group, patients in the reocclusion group had higher 24‐h (15 vs. 13) and 7‐day (15 vs. 9) NIHSS scores, 90‐day mRS scores (4 vs. 3), and 90‐day mortality rates (34.1% vs. 18.6%); lower rates of good prognosis (13.6% vs. 9.3%); and a higher incidence of early neurological deterioration (36.4% vs. 14.7%). Age, internal carotid artery occlusion (ICA), intravenous thrombolysis (IVT), number of thrombectomy passes, stent implantation, and levels of D‐dimer (adjusted odds ratio and 95% confidence interval: 0.97, 0.94–0.99; 2.40, 1.10–5.23; 2.21, 1.05–4.66; 2.60, 1.04–6.47; 0.25, 0.09–0.67; and 1.06, 1.01–1.12, respectively) were independently associated with 24‐h reocclusion. Interpretation: The prognosis of reocclusion after MT was poor. Timely evaluation of these factors including age, D‐dimer, ICA occlusion, IVT, number of passes, and stent implantation and appropriate intervention could reduce the incidence of reocclusion for Chinese stroke patients.
