Prognostic factors related to endovascular treatment of acute ischemic stroke with large vessel occlusion / 中华老年心脑血管病杂志

ABSTRACT

Objective To explore the influencing factors for long-term poor prognosis of patients with acute ischemic stroke with large vessel occlusion(LVO-AIS)in the course of intravascular treatment.Methods A total of 123 LVO-AIS patients undergoing vascular recanalization in Department of Neurology of Tianmen First People's Hospital from January 2021 to December 2022 were consecutively recruited,and according to their modified Rankin Scale(mRS)score at 90 d after surgery,they were divided into good prognosis group(mRS≤2,n=58)and poor prognosis group(mRS＞2,n=65).Their general clinical data were compared between the two groups.Multi-variate logistic regression analysis was applied to identify the risk factors of poor prognosis in LVO-AIS patients.Results The good ratio of collateral circulation in good prognosis group was higher than that in poor prognosis group(94.83％vs 47.69％,P＜0.01).Multivariate logistic regression analysis showed that age(OR=1.092,95％CI:0.989-1.205,P=0.046),diabetes(OR=0.122,95％CI:0.026-0.561,P=0.007),symptomatic intracranial hemorrhage(OR=0.038,95％C I:0.002-0.656,P=0.024),and poor collateral circulation(OR=0.037,95％CI:0.007-0.196,P=0.000)were independent risk factors for poor prognosis in LVO-AIS patients after intravascular treatment.Conclusion For the LVO-AIS patients,those with advanced age,di-abetes,symptomatic intracranial hemorrhage and poor collateral circulation are prone to poor prognosis after intravascular treatment.
