Efficacy and safety of intravascular intervention therapy in patients with mild stroke and acute large vessel occlusion / 中华老年心脑血管病杂志

ABSTRACT

Objective To investigate the effectiveness and safety of EVT in mild stroke patients with ALVO.Methods A total of 124 mild stroke patients with ALVO treated in our hospital were enrolled and randomly divided into control group(n=64)and observation group(n=60).The control group was given routine treatment,while the observation group received EVT treat-ment besides routine treatment.NIHSS score,BI score,and mRS score were compared between the two groups to evaluate the postoperative safety of EVT treatment.Results The NIHSS scores on the 7th and 14th days,and at discharge were significantly lower in the observation group and control group than those at admission(P＜0.05),and those of the former group were obvi-ously decreased than those of the latter group at the corresponding time points(P＜0.01).On the 7th,14th,and discharge days,the BI score of both groups were significantly increased compared to those at admission(P＜0.05),with the scores in the observation group higher than those of the control group at above time points(P＜0.01).The ratio of the patients having mRS score ≤2 point was larger in the observation group than the control group(96.67％vs 84.38％,P＜0.05).One case in the observation group experienced asymptomatic intracranial hemorrhage,and no oth-er adverse events were observed.Conclusion EVT can improve the prognosis of mild stroke pa-tients with ALVO,but does not significantly increases the incidence of adverse events.
