Differences in measurement of the extent of acute ischemic stroke using the Alberta Stroke Program Early Computed Tomographic Score (ASPECTS) by non-contrast computed tomography (CT-ASPECTS stratum) and diffusion-weighted imaging (DWI-ASPECTS stratum) may impact the efficacy of endovascular therapy (EVT) in patients with a large ischemic core.
The RESCUE-Japan LIMIT (Recovery by Endovascular Salvage for Cerebral Ultra-acute Embolism Japan-Large IscheMIc core Trial) was a multicenter, open-label, randomized clinical trial that evaluated the efficacy and safety of EVT in patients with ASPECTS of 3-5. CT-ASPECTS was prioritized when both CT-ASPECTS and DWI-ASPECTS were measured. The effects of EVT on the modified Rankin Scale (mRS) score at 90 days were assessed separately for each stratum.
Among 183 patients, 112 (EVT group, 53; No-EVT group, 59) were in the CT-ASPECTS stratum and 71 (EVT group, 40; No-EVT group, 31) in the DWI-ASPECTS stratum. The common odds ratio (OR) (95% confidence interval) of the EVT group for one scale shift of the mRS score toward 0 was 1.29 (0.65-2.54) compared to the No-EVT group in CT-ASPECTS stratum, and 6.15 (2.46-16.3) in DWI-ASPECTS stratum with significant interaction between treatment assignment and mode of imaging study (P=0.002). There were significant interactions in the improvement of the National Institutes of Health Stroke Scale score at 48 hours (CT-ASPECTS stratum: OR, 1.95; DWIASPECTS stratum: OR, 14.5; interaction P=0.035) and mortality at 90 days (CT-ASPECTS stratum: OR, 2.07; DWI-ASPECTS stratum: OR, 0.23; interaction P=0.008).
Patients with ASPECTS of 3-5 on MRI benefitted more from EVT than those with ASPECTS of 3-5 on CT.
使用阿尔伯塔卒中项目早期计算机断层扫描评分(ASPECTS),通过非增强计算机断层扫描(CT - ASPECTS 层)和扩散加权成像(DWI - ASPECTS 层)来测量急性缺血性卒中范围的差异,可能会影响大缺血核心患者血管内治疗(EVT)的疗效。
RESCUE - 日本 LIMIT(日本超急性脑栓塞血管内挽救恢复 - 大缺血核心试验)是一项多中心、开放标签、随机临床试验,评估了 ASPECTS 为 3 - 5 的患者接受 EVT 的疗效和安全性。当同时测量 CT - ASPECTS 和 DWI - ASPECTS 时,优先采用 CT - ASPECTS。分别评估了各层中 EVT 对 90 天时改良 Rankin 量表(mRS)评分的影响。
183 例患者中,112 例(EVT 组 53 例,非 EVT 组 59 例)在 CT - ASPECTS 层,71 例(EVT 组 40 例,非 EVT 组 31 例)在 DWI - ASPECTS 层。与 CT - ASPECTS 层的非 EVT 组相比,EVT 组 mRS 评分向 0 移动一个等级的共同优势比(OR)(95%置信区间)为 1.29(0.65 - 2.54),而在 DWI - ASPECTS 层为 6.15(2.46 - 16.3),治疗分配与影像学研究方式之间存在显著交互作用(P = 0.002)。在 48 小时时美国国立卫生研究院卒中量表评分的改善(CT - ASPECTS 层:OR,1.95;DWI - ASPECTS 层:OR,14.5;交互作用 P = 0.035)和 90 天时的死亡率(CT - ASPECTS 层:OR,2.07;DWI - ASPECTS 层:OR,0.23;交互作用 P = 0.008)方面存在显著交互作用。
MRI 上 ASPECTS 为 3 - 5 的患者比 CT 上 ASPECTS 为 3 - 5 的患者从 EVT 中获益更多。
