BACKGROUND Endovascular therapy (ET) has emerged as a highly effective treatment for acute large vessel occlusion stroke (LVOS). Tools that facilitate optimal patient selection of patients for ET are needed in order to maximize therapeutic benefit in a cost-effective manner. Several pre-intervention prognostic scores for prediction of outcomes in LVOS patients and patient selection for ET have been developed and validated, but their clinical use has been limited. Here, we review existing pre-intervention prognostic scores, compare their prognostic accuracies and levels of validation and identify gaps in current knowledge. SUMMARY We have reviewed published literature pertinent to development, validation, and implementation of pre-intervention prognostic scores for LVOS. Using receiver operating characteristic curve analysis, the prognostic accuracies of validated pre-interventional scores (Pittsburgh Response to Endovascular therapy [PRE], Totaled Health Risks in Vascular Events [THRIVE], Houston Intra-Arterial Therapy-2 (HIAT-2), Stroke Prognostication using Age and NIHSS [SPAN-100]) were compared in published work. Pre-intervention scores predicted functional out comes at 3 months with moderate prognostic accuracies (area under the receiver operator characteristic curve range 0.68-0.73). Using successful reperfusion (mTICI 2B/3) as the therapeutic objective of ET and 3-month modified Rankin Score 0-2 as good clinical outcome, patients most likely to clinically benefit from endovascular reperfusion can be identified using the PRE and HIAT-2 scores. Scores that incorporate collateral imaging or perfusion-based estimation of core and penumbra have not been published. Existing scores are predominantly limited to anterior circulation LVOS, and implementation studies of pre-interventional scores are lacking. KEY MESSAGES Pre-intervention prognostic scores can serve as useful adjuncts for patient selection in ET for acute LVOS. Pre-intervention scores including HIAT-2, THRIVE, SPAN-100, and PRE have comparable moderate prognostic accuracies for good 3-month outcomes and can identify patients who derive maximal benefit from successful reperfusion. Improvements in prognostic accuracy may be achieved by incorporating variables such as collateral status and perfusion imaging data. Implementation and impact studies using pre-intervention scores are needed to guide clinical application.

大血管闭塞卒中血管内治疗中早期预后和患者选择的干预前预后评分回顾。

背景血管内治疗(ET)已成为急性大血管闭塞性卒中(LVOS)的一种高效治疗方法。为了以具有成本效益的方式最大化治疗益处,需要有利于最佳患者选择 ET 患者的工具。已经开发和验证了几种用于预测 LVOS 患者结局和 ET 患者选择的干预前预后评分,但它们的临床应用受到限制。在这里,我们回顾了现有的干预前预后评分,比较了它们的预后准确性和验证水平,并确定了当前知识的差距。总结 我们回顾了与 LVOS 干预前预后评分的开发、验证和实施相关的已发表文献。使用受试者工作特征曲线分析,经验证的介入前评分的预后准确性(匹兹堡对血管内治疗的反应 [PRE]、血管事件中的总健康风险 [THRIVE]、休斯顿动脉内治疗 2 (HIAT-2)、使用年龄和 NIHSS 的中风预后 [SPAN -100])在已发表的作品中进行了比较。干预前评分预测功能结果在 3 个月时出现,具有中等预后准确性(接受者操作员特征曲线下面积为 0.68-0.73)。使用成功再灌注 (mTICI 2B/3) 作为 ET 的治疗目标和 3 个月修正 Rankin 评分 0-2 作为良好临床结果,可以使用 PRE 和 HIAT-2 评分确定最有可能从血管内再灌注临床获益的患者. 包含侧支成像或基于灌注的核心和半影估计的分数尚未公布。现有的评分主要限于前循环 LVOS,缺乏介入前评分的实施研究。关键信息 干预前预后评分可作为 ET 中急性 LVOS 患者选择的有用辅助手段。包括 HIAT-2、THRIVE、SPAN-100 和 PRE 在内的干预前评分对于 3 个月的良好预后具有相当的中等预后准确性,并且可以识别从成功再灌注中获得最大益处的患者。可以通过合并诸如侧支状态和灌注成像数据等变量来提高预后准确性。需要使用干预前评分的实施和影响研究来指导临床应用。缺乏干预前分数的实施研究。关键信息 干预前预后评分可作为 ET 中急性 LVOS 患者选择的有用辅助手段。包括 HIAT-2、THRIVE、SPAN-100 和 PRE 在内的干预前评分对于 3 个月的良好预后具有相当的中等预后准确性,并且可以识别从成功再灌注中获得最大益处的患者。可以通过合并诸如侧支状态和灌注成像数据等变量来提高预后准确性。需要使用干预前评分的实施和影响研究来指导临床应用。缺乏干预前分数的实施研究。关键信息 干预前预后评分可作为 ET 中急性 LVOS 患者选择的有用辅助手段。包括 HIAT-2、THRIVE、SPAN-100 和 PRE 在内的干预前评分对于 3 个月的良好预后具有相当的中等预后准确性,并且可以识别从成功再灌注中获得最大益处的患者。可以通过合并诸如侧支状态和灌注成像数据等变量来提高预后准确性。需要使用干预前评分的实施和影响研究来指导临床应用。和 PRE 对于良好的 3 个月结果具有相当的中等预后准确性,并且可以识别从成功再灌注中获得最大益处的患者。可以通过合并诸如侧支状态和灌注成像数据等变量来提高预后准确性。需要使用干预前评分的实施和影响研究来指导临床应用。和 PRE 对于良好的 3 个月结果具有相当的中等预后准确性,并且可以识别从成功再灌注中获得最大益处的患者。可以通过合并诸如侧支状态和灌注成像数据等变量来提高预后准确性。需要使用干预前评分的实施和影响研究来指导临床应用。
