Abstract
Objective To investigate the recurrence rate and mortality of cerebral ischemic stroke in patients with vertebral artery origin occlusion (VAOO). <br> Methods According to the verification of digital subtraction angiography (DSA), 156 cases of unilateral vertebral artery origin occlusion were divided into 2 groups: symptomatic group (n=98) and asymptomatic group (n=58). The follow-up study of these patients were performed for at least 2 years to observe newly occurred cerebral infarction and death from any cause. <br> Results The annual newly occurred cerebral infarction rate was 5.1% and the annual mortality rate was 0.4% in the patients with VAOO. The cumulative incidence of newly occurred cerebral infarction in symptomatic group and asymptomatic group didn’t have statistical signiifcance (P>0.05). Kaplan-Meier analysis showed that there were no signiifcant differences in the incidence of endpoint event and the proportion of opened collateral circulation between symptomatic group and asymptomatic group (P=0.690;P=0.566; 23.5%vs 27.6%, respectively). The patient ratio of the collateral circulation in patients with new cerebral infarction didn’t have obvious signiifcance (35.7%vs 22.7%,P=0.148). <br> Conclusion The annual new cerebral infarction rate of patients with VAOO is 5.1%, and the prognosis is relatively good.关键词
