1急性缺血性卒中静脉阿替普酶溶栓治疗的纳入和排除标准的科学依据美国心脏协会/美国卒中协会对医疗卫生专业人员发布的声明(续前)显示文摘19 颅内出血史 根据最初的 FDA 标签和2013年AHA/ASA指南,颅内出血史是静脉阿替普酶治疗缺血性卒中的一项额外禁忌证或排除标准。最近修订后的标签仅将近期 ICH 列为一项警告,并且在禁忌证中删除了ICH史。与前面讨论的静脉阿替普酶治疗排除标准相似,文献回顾仅在大样本回顾性研究中发现了少量这类病例。缺乏相关数据可能是修订后的FDA 标签不再将 ICH 史作为禁忌证而仅将近期ICH 列为一项警告的原因。在这种情况下,FDA 如何定义“近期”一词尚不清楚。有趣的是,对在静脉阿替普酶治疗前通过 MRI 检测脑微出血( cerebral microbleed, CMBs)存在情况进行的研究可为这个卒中亚组患者提供更多的见解。从病理生理学角度,这种微出血的原因尚不清楚,可能反映再灌注损伤或脑血管自动调节功能破坏。因此,在静脉阿替普酶治疗后出现这些损害可能没有意义或是人为信号。Dawn O.

2Lesion-symptom mapping with NIHSS sub-scores in ischemic stroke patients显示文摘Background Lesion-symptom mapping(LSM)is a statistical technique to investigate the population-specific relationship between structural integrity and post-stroke clinical outcome.In clinical practice,patients are commonly evaluated using the National Institutes of Health Stroke Scale(NIHSS),an 11-domain clinical score to quantitate neurological deficits due to stroke.So far,LSM studies have mostly used the total NIHSS score for analysis,which might not uncover subtle structure–function relationships associated with the specific sub-domains of the NIHSS evaluation.Thus,the aim of this work was to investigate the feasibility to perform LSM analyses with sub-score information to reveal category-specific structure–function relationships that a total score may not reveal.Methods Employing a multivariate technique,LSM analyses were conducted using a sample of 180 patients with NIHSS assessment at 48-hour post-stroke from the ESCAPE trial.The NIHSS domains were grouped into six categories using two schemes.LSM was conducted for each category of the two groupings and the total NIHSS score.Results Sub-score LSMs not only identify most of the brain regions that are identified as critical by the total NIHSS score but also reveal additional brain regions critical to each function category of the NIHSS assessment without requiring extensive,specialised assessments.Conclusion These findings show that widely available sub-scores of clinical outcome assessments can be used to investigate more specific structure–function relationships,which may improve predictive modelling of stroke outcomes in the context of modern clinical stroke assessments and neuroimaging.Deepthi Rajashekar Matthias Wilms M Ethan MacDonald Serena Schimert Michael D Hill Andrew Demchuk Mayank Goyal Sean P Dukelow Nils Daniel Forkert 2022Stroke & Vascular Neurology2022,7,2:7
