Because of several methodological limitations, previous studies focusing on the prevalence of large vessel occlusion in ischemic stroke (IS) patients provided conflicting results. We evaluated the incidence of IS with a visible arterial occlusion using a comprehensive population-based registry.
Patients with acute IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013-2017). All arterial imaging exams were reviewed to assess arterial occlusion. Annual incidence rates of IS (first-ever and recurrent events) and IS with a visible occlusion were calculated.
One thousand sixty cases of IS were recorded (mean age: 76.0±15.8 years, 53.9% women). Information about arterial imaging was available in 971 (91.6%) of them, and only preexisting dementia was independently associated with having missing information (odds ratio=0.34 [95% CI, 0.18-0.65], =0.001). Among these patients, 284 (29.2%) had a visible arterial occlusion. Occlusion site was the anterior circulation in 226 patients (23.3% of overall patients with available data) and the posterior circulation in 58 patients (6.0%). A proximal occlusion of the anterior circulation was observed in 167 patients (17.2%). The crude annual incidence rate of total IS per 100 000 was 138 (95% CI, 129-146). Corresponding standardized rates were 66 (95% CI, 50-82) to the World Health Organization and 141 (95% CI, 118-164) to the 2013 European populations. The crude annual incidence rate of IS with a visible arterial occlusion per 100 000 was 37 (95% CI, 33-41) and that of IS with a proximal occlusion of the anterior circulation was 22 (95% CI, 18-25). Corresponding standardized rates were 18 (95% CI, 10-26) and 10 (95% CI, 8-13) to the World Health Organization population, and 38 (95% CI, 26-50) and 23 (95% CI, 19-26) to the 2013 European population, respectively.
These results will be helpful to plan the need for thrombectomy-capable stroke center resources.
由于存在若干方法学限制，既往聚焦于缺血性卒中（IS）患者大血管闭塞发生率的研究结果存在差异。我们通过一项基于人群的注册研究，评估了使用综合人群登记系统发现的 IS 患者动脉闭塞的发生率。
采用基于人群的登记系统（2013-2017 年）前瞻性识别法国第戎市的急性 IS 患者。所有动脉影像学检查均进行了评估，以确定是否存在动脉闭塞。计算首次发生和复发事件的 IS 以及可见动脉闭塞的年度发生率。
共记录了 1060 例 IS（平均年龄：76.0±15.8 岁，53.9%为女性）。971 例患者（91.6%）的动脉影像学信息可用，仅预先存在痴呆与信息缺失独立相关（比值比=0.34[95%CI，0.18-0.65]，=0.001）。在这些患者中，284 例（29.2%）存在可见的动脉闭塞。前循环闭塞 226 例（总体可获取数据患者中占 23.3%），后循环闭塞 58 例（6.0%）。前循环近端闭塞 167 例（17.2%）。每 100000 人年总 IS 的粗发生率为 138（95%CI，129-146）。相应的标准化发生率为世界卫生组织标准 66（95%CI，50-82），2013 年欧洲人群标准 141（95%CI，118-164）。每 100000 人年可见动脉闭塞性 IS 的粗发生率为 37（95%CI，33-41），前循环近端闭塞性 IS 的发生率为 22（95%CI，18-25）。相应的标准化发生率为世界卫生组织人群标准 18（95%CI，10-26）和 2013 年欧洲人群标准 10（95%CI，8-13），为 38（95%CI，26-50）和 23（95%CI，19-26）。
这些结果将有助于规划可进行取栓治疗的卒中中心资源的需求。
