Introduction: Developing an effective stroke prevention strategy is crucial for elderly atrial fibrillation (AF) patients with dementia. This is due to the limited and inconsistent evidence available on this topic. In this nationwide, population-based cohort study, we aim to compare the effectiveness and safety of direct oral anticoagulants (DOACs) and warfarin in AF patients with dementia.

Patients and methods: We identified AF patients with dementia, aged 50 years or older, from Taiwan's National Health Insurance Research Database between 2010 and 2019. The primary outcome was a composite of hospitalizations due to ischemic stroke, acute myocardial infarction, intracranial hemorrhage, or major bleeding, as well as all-cause mortality. We used 1:1 propensity score matching and Cox proportional hazard models to adjust for confounding factors when comparing outcomes between warfarin and DOAC (apixaban, dabigatran, edoxaban, or rivaroxaban) users or warfarin and each individual DOAC.

Results: There were 2952 patients in the DOAC-warfarin matched cohort. The apixaban-, dabigatran-, edoxaban-, and rivaroxaban-warfarin matched cohorts had 2346, 2554, 1684, and 2938 patients, respectively. The DOAC group, when compared to warfarin, was associated with a lower risk of both the composite outcome (hazard ratio (HR), 0.81; 95% confidence interval (CI) 0.69-0.95) and ischemic stroke (HR 0.65; 95% CI 0.48-0.87). Apixaban (HR 0.79; 95% CI 0.66-0.94), dabigatran (HR 0.64; 95% CI 0.53-0.77), and rivaroxaban (HR 0.82; 95% CI 0.70-0.97) were also associated with a lower risk of the composite outcome.

Discussion and conclusion: Compared to warfarin, DOACs, whether as a group or apixaban, dabigatran, or rivaroxaban individually, were associated with a reduced risk of the composite outcome in elderly patients with concurrent AF and dementia.

导言:制定有效的中风预防策略对于老年心房颤动 (AF) 痴呆患者至关重要。这是因为这方面的证据有限且不一致。在这项基于人群的全国性队列研究中,我们旨在比较直接口服抗凝药(DOACs)和华法林对老年痴呆房颤患者的有效性和安全性:我们从 2010 年至 2019 年期间的台湾国民健康保险研究数据库中识别了 50 岁或以上的房颤痴呆患者。主要结果是缺血性中风、急性心肌梗死、颅内出血或大出血导致的住院治疗以及全因死亡率的复合结果。在比较华法林和DOAC(阿哌沙班、达比加群、依度沙班或利伐沙班)使用者之间或华法林和每种DOAC使用者之间的结果时,我们使用了1:1倾向得分匹配和Cox比例危险模型来调整混杂因素:DOAC与华法林匹配队列中有2952名患者。阿哌沙班、达比加群、依度沙班和利伐沙班-华法林匹配队列分别有 2346、2554、1684 和 2938 名患者。与华法林相比,DOAC组发生复合结局(危险比(HR)0.81;95% 置信区间(CI)0.69-0.95)和缺血性卒中(HR 0.65;95% CI 0.48-0.87)的风险较低。阿哌沙班(HR 0.79;95% CI 0.66-0.94)、达比加群(HR 0.64;95% CI 0.53-0.77)和利伐沙班(HR 0.82;95% CI 0.70-0.97)也与较低的综合结果风险相关:与华法林相比,DOACs(无论是作为一组药物还是阿哌沙班、达比加群或利伐沙班单独使用)与并发房颤和痴呆的老年患者的综合结局风险降低相关。

Introduction: Managing blood pressure in patients with large vessel occlusion affects infarct size and clinical outcomes. We examined how restoring blood flow impacts systemic blood pressure during mechanical thrombectomy.

Patients and methods: Patients with large vessel occlusion in the anterior circulation undergoing mechanical thrombectomy between June 2016 and January 2018 were screened. We included those treated under local anesthesia or conscious sedation and analyzed standardized anesthesia protocols to assess systolic and diastolic blood pressure levels throughout the procedure. The primary outcome was the change of blood pressure, compared 5 min before versus 5 min after the last recanalization attempt. Successful reperfusion was defined as Thrombolysis in Cerebral Infarction score ⩾ 2b.

Results: Of 134 patients, 117 (87%) achieved successful angiographic reperfusion, showing a notable systolic blood pressure drop 5 min after flow restoration (10.2 ± 14.6 vs 3.24 ± 8.65 mm Hg, p = 0.009). Successful angiographic reperfusion was a significant predictor for this decrease in multivariable logistic regression: OR = 1.34 (95% CI: 1.03-1.73, p = 0.0299). Among 66 patients not given circulation-affecting meds, a significant systolic pressure reduction was also observed (155 ± 17 mm Hg to 148 ± 17 mm Hg ; p < 0.001). No diastolic pressure changes were significant.

Discussion and conclusions: Flow restoration was associated with an immediate reduction of systolic blood pressure values in patients undergoing mechanical recanalization under local anesthesia or conscious sedation. This suggests a complex interplay between endovascular stroke therapy and cardiovascular hemodynamics.

导言:大血管闭塞患者的血压管理会影响梗死面积和临床预后。我们研究了在机械血栓切除术中恢复血流如何影响全身血压:筛选了 2016 年 6 月至 2018 年 1 月间接受机械血栓切除术的前循环大血管闭塞患者。我们纳入了在局部麻醉或有意识镇静下接受治疗的患者,并分析了标准化麻醉方案,以评估整个手术过程中的收缩压和舒张压水平。主要结果是血压的变化,比较最后一次再灌注尝试前 5 分钟和尝试后 5 分钟的血压变化。脑梗塞溶栓评分⩾ 2b 定义为再灌注成功:134例患者中,117例(87%)血管再灌注成功,血流恢复后5分钟收缩压明显下降(10.2 ± 14.6 vs 3.24 ± 8.65 mm Hg,p = 0.009)。在多变量逻辑回归中,血管再灌注成功是导致血压下降的重要预测因素:OR = 1.34 (95% CI: 1.03-1.73, p = 0.0299)。在 66 名未服用影响循环药物的患者中,也观察到收缩压显著降低(从 155 ± 17 mm Hg 降至 148 ± 17 mm Hg;p 讨论和结论:在局部麻醉或有意识镇静状态下接受机械再通术的患者,血流恢复与收缩压值的立即降低有关。这表明血管内卒中治疗与心血管血流动力学之间存在复杂的相互作用。

Purpose: We aimed to synthesize the information needs of people with stroke (PwS) in recurrent stroke prevention.

Methods: In this scoping review we searched Medline (via PubMed), CINAHL, and PsycINFO from inception to June 5, 2023, to identify all studies describing the information needs of people 18 years and older who have suffered a stroke or transient ischemic attack within the past 5 years. We included qualitative and quantitative studies from developed countries published in German or English. Data analysis was performed following Arksey and O'Malley's methodological framework for scoping reviews.

Findings: We screened 5822 records for eligibility and included 36 articles published between 1993 and 2023. None of the included studies used a comprehensive framework or defined information needs. Based on statements from PwS and their caregivers, PwS needed information on treatment, etiology, effects of stroke, prognosis, rehabilitation, discharge, life changes, care role, support options, information sources, and hospital procedures. The most frequently expressed needs were information on the treatment (77.8%) and stroke etiology (63.9%). The primary information source was healthcare professionals (85.7%), followed by written information (71.4%), family and friends (42.6%), and the internet (35.7%), with information provided directly by healthcare professionals being preferred. The timing of information transfer is often described as too early.

Conclusion: PwS are primarily interested in clinical information about stroke, for example, treatment and etiology, and less often in information about daily life, for example, rehabilitation, the role of care, or lifestyle changes. PwS prefer to receive information directly from healthcare professionals. Developing a shared understanding of PwS's information needs is crucial to implement suitable strategies and programs for dealing with these needs in clinical practice.

目的:我们旨在综述脑卒中患者(PwS)在预防复发性脑卒中方面的信息需求:在此次范围界定综述中,我们检索了 Medline(通过 PubMed)、CINAHL 和 PsycINFO 从开始到 2023 年 6 月 5 日的所有研究,以确定所有描述在过去 5 年中遭受过中风或短暂性脑缺血发作的 18 岁及以上人群信息需求的研究。我们纳入了发达国家以德语或英语发表的定性和定量研究。数据分析按照 Arksey 和 O'Malley 的范围界定综述方法框架进行:我们筛选了 5822 条符合条件的记录,并纳入了在 1993 年至 2023 年间发表的 36 篇文章。所纳入的研究均未使用综合框架或定义信息需求。根据卒中患者及其照护者的陈述,卒中患者需要的信息包括治疗、病因、卒中的影响、预后、康复、出院、生活变化、照护角色、支持选择、信息来源以及住院程序。最常表达的需求是治疗信息(77.8%)和中风病因信息(63.9%)。主要的信息来源是医护人员(85.7%),其次是书面信息(71.4%)、家人和朋友 (42.6%)以及互联网(35.7%),其中医护人员直接提供的信息更受欢迎。信息传递的时间通常被描述为过早:结论:患者主要对有关中风的临床信息感兴趣,如治疗和病因,而对日常生活信息较 少感兴趣,如康复、护理的作用或生活方式的改变。他们更愿意直接从医护人员那里获取信息。要在临床实践中实施适当的策略和计划来满足这些需求,对患者的信息需求达成共识是至 关重要的。

Introduction: Patients with acute ischemic stroke (AIS) and large-vessel occlusion are frequently transferred by emergency physicians (EPs) from primary to comprehensive stroke centers (CSC) for thrombectomy, particular when thrombolysed. Data on complications during such transfers are highly limited.

Patients and methods: Consecutive AIS patients transferred between 01/2015 and 10/2021 to our CSC were included. Associations of major (MACO) and minor (MICO) complications with clinical and imaging data were assessed.

Results: In total, 985 patients were included in the analysis (58.5% thrombolysed). MACO developed in 1.6%, MICO in 14.6%. Compared to patients without complications (NOCO), patients with MACO did not differ in terms of demographics, cerebrovascular risk factors, or site of vessel occlusion. They had more severe strokes (p = 0.026), neurological worsening was more severe (p = 0.008), and transport duration was longer (p = 0.050) but geographical distances did not differ. Thrombolysed patients had any complication more often than patients without thrombolysis (20.3% vs 10.5%; p< 0.001); however, this finding was driven by patients with MICO (p< 0.001) only (MACO: p = 0.804). No associations were observed between stroke severity and complications in either thrombolysed or nonthrombolysed patients. Neurological deterioration during transfer was observed in 21.2%, but multivariate analysis revealed no association with thrombolysis (OR 0.962; 95%CI 0.670-1.380, p = 0.832). Asymptomatic intracerebral hemorrhage was present in 1.1%, symptomatic in 0.1%.

Discussion and conclusion: In this large cohort, no patient-specific factor increasing the risk of complications during interhospital transfer was identified. Specifically, our results do not indicate that thrombolysis increases MACO. Hence, interhospital transfer without EPs appears reasonable in most patients.

导言:急性缺血性卒中(AIS)和大血管闭塞患者经常被急诊医生(EPs)从初级卒中中心转至综合卒中中心(CSC)进行血栓切除术,尤其是溶栓治疗。有关此类转运过程中并发症的数据非常有限:患者和方法:纳入2015年1月至2021年10月期间转入我们CSC的连续AIS患者。评估主要(MACO)和次要(MICO)并发症与临床和影像学数据的关联:共有985名患者被纳入分析(58.5%的患者接受了溶栓治疗)。1.6%的患者出现了MACO,14.6%的患者出现了MICO。与无并发症(NOCO)患者相比,MACO患者在人口统计学、脑血管风险因素或血管闭塞部位方面没有差异。他们的中风程度更严重(p = 0.026),神经功能恶化程度更严重(p = 0.008),转运时间更长(p = 0.050),但地理距离没有差异。与未溶栓的患者相比,溶栓患者出现并发症的比例更高(20.3% vs 10.5%;p 0.001);但这一结果仅出现在 MICO 患者身上(p 0.001)(MACO:p = 0.804)。在溶栓或非溶栓患者中,均未观察到中风严重程度与并发症之间的关联。21.2% 的患者在转运过程中出现神经功能恶化,但多变量分析显示这与溶栓无关(OR 0.962; 95%CI 0.670-1.380, p = 0.832)。1.1%的患者为无症状脑出血,0.1%的患者为有症状脑出血:在这一大型队列中,没有发现患者特异性因素会增加院间转运过程中的并发症风险。特别是,我们的结果并未表明溶栓会增加MACO。因此,对于大多数患者来说,不使用 EPs 的院间转运似乎是合理的。

Introduction: Thrombectomy complications remain poorly explored. This study aims to characterize periprocedural intracranial vessel perforation including the effect of thrombolysis on patient outcomes.

Patients and methods: In this multicenter retrospective cohort study, consecutive patients with vessel perforation during thrombectomy between January 2015 and April 2023 were included. Vessel perforation was defined as active extravasation on digital subtraction angiography. The primary outcome was modified Rankin Scale (mRS) at 90 days. Factors associated with the primary outcome were assessed using proportional odds models.

Results: 459 patients with vessel perforation were included (mean age 72.5 ± 13.6 years, 59% female, 41% received thrombolysis). Mortality at 90 days was 51.9% and 16.3% of patients reached mRS 0-2 at 90 days. Thrombolysis was not associated with worse outcome at 90 days. Perforation of a large vessel (LV) as opposed to medium/distal vessel perforation was independently associated with worse outcome at 90 days (aOR 1.709, p = 0.04) and LV perforation was associated with poorer survival probability (HR 1.389, p = 0.021). Patients with active bleeding >20 min had worse survival probability, too (HR 1.797, p = 0.009). Thrombolysis was not associated with longer bleeding duration. Bleeding cessation was achieved faster by permanent vessel occlusion compared to temporary measures (median difference: 4 min, p < 0.001).

Discussion and conclusion: Vessel perforation during thrombectomy is a severe and frequently fatal complication. This study does not suggest that thrombolysis significantly attributes to worse prognosis. Prompt cessation of active bleeding within 20 min is critical, emphasizing the need for interventionalists to be trained in complication management.

导言:对血栓切除术并发症的研究仍然很少。本研究旨在描述围手术期颅内血管穿孔的特征,包括溶栓对患者预后的影响:在这项多中心回顾性队列研究中,纳入了 2015 年 1 月至 2023 年 4 月期间在血栓切除术中发生血管穿孔的连续患者。血管穿孔的定义是数字减影血管造影中出现活动性外渗。主要结果是90天后的改良Rankin量表(mRS)。采用比例赔率模型评估与主要结果相关的因素:共纳入 459 名血管穿孔患者(平均年龄为 72.5 ± 13.6 岁,59% 为女性,41% 接受了溶栓治疗)。90天后的死亡率为51.9%,16.3%的患者在90天后达到mRS 0-2。溶栓与90天后的预后不相关。大血管(LV)穿孔与中/远端血管穿孔相比,与90天后较差的预后独立相关(aOR 1.709,p = 0.04),LV穿孔与较差的生存概率相关(HR 1.389,p = 0.021)。活动性出血时间超过20分钟的患者生存概率也较低(HR 1.797,P = 0.009)。溶栓与出血持续时间延长无关。与临时措施相比,永久性血管闭塞能更快地止血(中位数差异为 4 分钟,P = 0.009):讨论与结论:血栓切除术中的血管穿孔是一种严重且经常致命的并发症。本研究并未表明溶栓会明显导致预后恶化。在 20 分钟内及时停止活动性出血至关重要,这强调了介入医师接受并发症处理培训的必要性。

Introduction: Atrial fibrillation (AF) detected after stroke (AFDAS) may represent a distinct clinical entity to that of known AF (KAF). However, there is limited long-term outcome data available for patients with AFDAS. More information regarding prognosis in AFDAS is required to inform future trial design in these patients.

Patients and methods: We used data (2015-2019) from a national prospective stroke registry of consecutive patients with acute ischaemic stroke and AF. AFDAS was defined as a new diagnosis of AF after stroke detected on electrocardiograph or cardiac monitoring. The co-primary endpoints were: (1) all-cause mortality; (2) recurrent major adverse cardiovascular events (MACE) at 3 years. Secondary endpoints were: (1) recurrent stroke; (2) functional outcome at discharge; (3) presence of co-existing stroke mechanisms.

Results: 583 patients were included. After a median follow-up of 2.65 years (cumulative 1064 person-years) 309 patients died and 23 had recurrent MACE. Compared with AFDAS, KAF was associated with a higher risk of all-cause mortality (adjusted Hazard Ratio (aHR) 1.56, 95% CI 1.12-2.18), a higher prevalence of co-existing stroke mechanisms (adjusted odds ratio (aOR) 2.28, 95% CI 1.14-4.59), but not poor functional outcome (aOR 1.61, 95% CI 0.98-2.64). A trend towards a higher risk of MACE was observed in patients with KAF, but this was limited by statistical power (aHR 2.90, 95% CI 0.67-12.51). All 14 recurrent strokes occurred in the KAF group (Log-rank p = 0.03).

Discussion and conclusion: These data provide further evidence that AFDAS differs to KAF with respect to risk of recurrent stroke, MACE, and all-cause mortality.

导言:卒中后发现的心房颤动(AFDAS)与已知的心房颤动(KAF)可能是不同的临床实体。然而,目前针对 AFDAS 患者的长期预后数据非常有限。需要更多有关 AFDAS 预后的信息,以便为这些患者未来的试验设计提供参考:我们使用了来自全国性前瞻性卒中登记处的数据(2015-2019 年),登记对象为急性缺血性卒中合并房颤的连续患者。AFDAS的定义是心电图或心脏监测发现卒中后新诊断的房颤。共同主要终点为(1) 全因死亡率;(2) 3 年内复发的主要不良心血管事件 (MACE)。次要终点为(1) 复发中风;(2) 出院时的功能预后;(3) 是否同时存在中风机制:结果:共纳入 583 名患者。中位随访 2.65 年(累计 1064 人年)后,309 名患者死亡,23 名患者复发 MACE。与 AFDAS 相比,KAF 与较高的全因死亡风险(调整后危险比 (aHR) 1.56,95% CI 1.12-2.18)、较高的并存卒中机制发生率(调整后几率比 (aOR) 2.28,95% CI 1.14-4.59)相关,但与较差的功能预后无关(aOR 1.61,95% CI 0.98-2.64)。在 KAF 患者中观察到 MACE 风险较高的趋势,但这受到统计能力的限制(aHR 2.90,95% CI 0.67-12.51)。所有 14 例复发性脑卒中均发生在 KAF 组(Log-rank p = 0.03):这些数据进一步证明,在复发性卒中、MACE 和全因死亡率风险方面,AFDAS 与 KAF 存在差异。

Introduction: Endovascular treatment (EVT) improves outcomes for basilar artery occlusion (BAO) with moderate-to-severe symptoms. However, the best treatment for mild symptoms (NIHSS score 0-10 and 0-5) remains unclear. This study compared EVT ± IVT to IVT alone in BAO patients with mild symptoms.

Patients and methods: From the SITS-International Stroke Treatment Register, we included BAO patients with available baseline NIHSS score, treated by EVT, IVT, or both within 6 h of symptom onset from 2013 to 2021. Using the Doubly Robust approach (propensity score matching plus multivariable logistic regression), we analyzed efficacy (3-month mRS) and safety (SICH and 3-month death) outcomes for EVT ± IVT versus IVT alone in BAO patients with NIHSS scores 0-10 and 0-5.

Results: 1426 patients were included. For NIHSS scores 0-10 (180 matched, 1:1 ratio), outcomes were similar between EVT ± IVT and IVT alone groups. For NIHSS scores 0-5 (89 matched, 1:1 ratio), EVT ± IVT was associated with worse outcomes compared to IVT alone (mRS 0-2, aOR 0.20 [95% CI 0.06-0.61]; p = 0.005; mRS 0-3, aOR 0.27 [95% CI 0.08-0.89]; p = 0.031), but safety outcomes were similar.

Discussion: In early-treated BAO patients with mild symptoms, defined as NIHSS 0-10, there were no significant differences in outcomes between EVT ± IVT and IVT alone. However, for very mild symptoms, defined as NIHSS 0-5, IVT alone was associated with better outcomes compared to EVT ± IVT.Conclusion: Randomized trials are crucial to determine the optimal reperfusion therapy for BAO patients with mild symptoms.

简介:血管内治疗(EVT)可改善具有中重度症状的基底动脉闭塞(BAO)的治疗效果。然而,轻度症状(NIHSS 评分 0-10 分和 0-5 分)的最佳治疗方法仍不明确。本研究对轻度症状的 BAO 患者进行了 EVT ± IVT 与单纯 IVT 的比较:从 SITS 国际卒中治疗登记册中,我们纳入了 2013 年至 2021 年期间有基线 NIHSS 评分、在症状出现 6 小时内接受过 EVT、IVT 或两者治疗的 BAO 患者。我们采用双重稳健法(倾向评分匹配加多变量逻辑回归)分析了NIHSS评分为0-10分和0-5分的BAO患者接受EVT±IVT治疗与单独接受IVT治疗的疗效(3个月mRS)和安全性(SICH和3个月死亡):结果:共纳入1426名患者。对于 NIHSS 评分为 0-10 分(180 例匹配,比例为 1:1)的患者,EVT ± IVT 组和单纯 IVT 组的结果相似。对于NIHSS评分0-5分(89例匹配,1:1比例),EVT±IVT组与单纯IVT组相比预后较差(mRS 0-2,aOR 0.20 [95% CI 0.06-0.61];p = 0.005;mRS 0-3,aOR 0.27 [95% CI 0.08-0.89];p = 0.031),但安全性预后相似:讨论:在早期治疗的轻度症状(定义为 NIHSS 0-10)BAO 患者中,EVT ± IVT 和单独 IVT 的疗效无显著差异。然而,对于症状非常轻微(定义为 NIHSS 0-5)的患者,与 EVT ± IVT 相比,单纯 IVT 的疗效更好:结论:随机试验对于确定症状轻微的 BAO 患者的最佳再灌注疗法至关重要。

Introduction: The risk of ischemic stroke and intracerebral hemorrhage (ICH) with intensive lipid control by statins among patients with atrial fibrillation (AF) who require direct oral anticoagulants (DOAC) is unclear. We aimed to determine the risks of ischemic stroke and ICH in AF patients treated with DOAC and statins.

Patients and methods: In a population-based retrospective cohort study, we identified AF patients concurrently on DOAC and statins from 2015 to 2021 in Hong Kong. Primary outcome was ischemic stroke. Secondary outcomes were ICH and death. We correlated study outcomes with low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) as time-varying, continuous variables with restricted cubic spline. In secondary analyses, the risks of study outcomes with statin intensity (low, moderate, high) were determined by multivariable time-dependent marginal structural Cox models.

Results: We identified 32,752 AF patients co-prescribed with DOAC and statins. Lower LDL-C (p < 0.001) and higher HDL-C (p < 0.001) levels were associated with lower risk of ischemic stroke but not significantly associated with ICH. LDL-C of <1.8 mmol/L (70 mg/dL) was not associated with mortality (19.6% vs 18.4%, difference 1.2% [95% CI -0.35 to 2.13]). High-intensity statin was associated with a lower risk of ischemic stroke compared with low-intensity statin (weighted Cox-specific hazard ratio [95% CI]: 0.82 [0.67-0.99], p = 0.040) independent of LDL-C levels. Similar associations were found in 11,444 AF patients with a history of ischemic stroke.

Discussion and conclusion: Intensive lipid control by high-intensity statins was associated with a lower risk of ischemic stroke in AF patients who required DOACs and did not appear to increase the risk of ICH.

导言:在需要直接口服抗凝药(DOAC)的房颤(AF)患者中,使用他汀类药物强化血脂控制缺血性卒中和脑内出血(ICH)的风险尚不明确。我们旨在确定接受 DOAC 和他汀类药物治疗的房颤患者发生缺血性卒中和 ICH 的风险:在一项基于人群的回顾性队列研究中,我们确定了 2015 年至 2021 年期间在香港同时服用 DOAC 和他汀类药物的房颤患者。主要结果为缺血性卒中。次要结局为 ICH 和死亡。我们将研究结果与作为时变连续变量的低密度脂蛋白胆固醇(LDL-C)和高密度脂蛋白胆固醇(HDL-C)相关联,并使用限制性立方样条。在二次分析中,研究结果与他汀类药物强度(低、中、高)的风险是通过多变量时间依赖性边际结构 Cox 模型确定的:结果:我们确定了 32,752 名同时服用 DOAC 和他汀类药物的房颤患者。低密度脂蛋白胆固醇较低(p p = 0.040)与低密度脂蛋白胆固醇水平无关。在 11,444 名有缺血性中风病史的房颤患者中也发现了类似的关联:通过高强度他汀类药物强化血脂控制与需要 DOACs 的房颤患者缺血性卒中风险降低有关,似乎不会增加 ICH 风险。

Background: Existing radiological markers of hematoma expansion (HE) show modest predictive accuracy. We aim to investigate a novel radiological marker that co-localizes findings from non-contrast CT (NCCT) and CT angiography (CTA) to predict HE.

Methods: Consecutive acute intracerebral hemorrhage patients admitted at Foothills Medical Centre in Calgary, Canada, were included. The Black-&-White sign was defined as any visually identified spot sign on CTA co-localized with a hypodensity sign on the corresponding NCCT. The primary outcome was hematoma expansion (⩾6 mL or ⩾33%). Secondary outcomes included absolute (<3, 3-6, 6-12, ⩾12 mL) and relative (0%, <25%, 25%-50%, 50%-75%, or >75%) hematoma growth scales.

Results: Two-hundred patients were included, with 50 (25%) experiencing HE. Forty-four (22%) showed the spot sign, 69 (34.5%) the hypodensity sign, and 14 (7%) co-localized both as the Black-&-White sign. Those with the Black-&-White sign had higher proportions of HE (100% vs 19.4%, p < 0.001), greater absolute hematoma growth (23.37 mL (IQR = 15.41-30.27) vs 0 mL (IQR = 0-2.39), p < 0.001) and relative hematoma growth (120% (IQR = 49-192) vs 0% (0-15%), p < 0.001). The Black-&-White sign had a specificity of 100% (95%CI = 97.6%-100%), a positive predictive value of 100% (95%CI = 76.8%-100%), and an overall accuracy of 82% (95%CI = 76%-87.1%). Among the 14 patients with the Black-&-White sign, 13 showed an absolute hematoma growth ⩾12 mL, and 10 experienced a HE exceeding 75% of the initial volume. The inter-rater agreement was excellent (kappa coefficient = 0.84).

Conclusion: The Black-&-White sign is a robust predictor of hematoma expansion occurrence and severity, yet further validation is needed to confirm these compelling findings.

背景:血肿扩大(HE)的现有放射学标志物显示出适度的预测准确性。我们旨在研究一种新型放射学标志物,它能将非对比 CT(NCCT)和 CT 血管造影(CTA)的结果共同定位,从而预测 HE:方法:纳入加拿大卡尔加里 Foothills 医疗中心收治的连续急性脑内出血患者。黑白征的定义是 CTA 上任何可视化识别的斑点征与相应 NCCT 上的低密度征共同定位。主要结果是血肿扩大(⩾6 mL 或 ⩾33%)。次要结果包括血肿增长绝对值(75%):共纳入 200 例患者,其中 50 例(25%)出现高血压。44人(22%)出现斑点征,69人(34.5%)出现低密度征,14人(7%)同时出现黑白征。黑白征的患者中 HE 的比例较高(100% 对 19.4%,p p p 结论):黑白征是血肿扩大发生和严重程度的可靠预测指标,但还需要进一步验证才能证实这些令人信服的发现。

Introduction: Endovascular thrombectomy stands as a pivotal component in the standard care for patients experiencing acute ischemic stroke with large vessel occlusion. Subsequent care for patients often extends to a neurological intensive care unit. While fluid management is integral to intensive care, the association between early fluid balance and neurological and functional outcomes post-thrombectomy has not yet been thoroughly investigated.

Methods: In a retrospective analysis of an observational, single-center study spanning from 2015 to 2021 at the University Medical Center Hamburg-Eppendorf, Germany, we enrolled stroke patients who underwent thrombectomy and received subsequent treatment in the ICU. Unfavorable functional and neurological outcome was defined as a mRS > 2 on day 90 after admission (mRS d90) or NIHSS > 5 at discharge, respectively. A multivariate regression model, adjusting for confounders, utilized the average fluid balance in the first 5 days to predict outcomes. Patients were dichotomized by their average fluid balance (>1 L vs <1 L) within the first 5 days, and a multivariate mRS d90 shift analysis was conducted after adjusting for covariates.

Results: Between 2015 and 2021, 1252 patients underwent thrombectomy, and 553 patients met the inclusion criteria (299 women [54%]). Unfavorable functional outcome was significantly associated with a higher daily average fluid balance in the first 5 days in the ICU (mRS d90 ⩽ 2: 0.3 ± 0.5 L, mRS d90 > 2: 0.7 ± 0.7 L, p = 0.02). The same association was observed for the NIHSS at discharge (NIHSS ⩽ 5: 0.3 ± 0.5 L; NIHSS > 5: 0.6 ± 0.6 L; p = 0.03). The mRS d90 shift analysis revealed significance for patients with an average fluid balance <1 L for better functional outcomes (adjusted odds ratio [AOR] 2.17; 95% confidence interval [CI] 1.54-3.07; p < 0.01).

Discussion: Fluid retention in post-thrombectomy stroke patients in the ICU is associated with poorer functional and neurological outcomes. Consequently, fluid retention emerges as an additional potential predictor for post-intervention stroke outcomes. Our findings provide an initial indication that preventing excessive fluid retention in stroke patients after endovascular thrombectomy could be beneficial for both functional and neurological recovery. Therefore, fluid retention might be an element to consider in optimizing fluid management for stroke patients.

导言:血管内血栓切除术是急性缺血性脑卒中大血管闭塞患者标准治疗的重要组成部分。对患者的后续护理通常延伸至神经重症监护病房。虽然液体管理是重症监护不可或缺的一部分,但血栓切除术后早期液体平衡与神经和功能预后之间的关系尚未得到深入研究:在对德国汉堡大学医疗中心(University Medical Center Hamburg-Eppendorf)2015 年至 2021 年的一项单中心观察性研究进行的回顾性分析中,我们纳入了接受血栓切除术并在重症监护室接受后续治疗的中风患者。入院后第 90 天的 mRS > 2(mRS d90)或出院时 NIHSS > 5 分别定义为功能和神经系统的不良预后。在调整了混杂因素后,多变量回归模型利用前 5 天的平均液体平衡来预测结果。根据患者的平均体液平衡(>1 L vs 结果)对其进行二分:2015年至2021年间,1252名患者接受了血栓切除术,553名患者符合纳入标准(299名女性[54%])。不利的功能预后与入住重症监护室前 5 天较高的日平均液体平衡显著相关(mRS d90 ⩽ 2:0.3 ± 0.5 L,mRS d90 > 2:0.7 ± 0.7 L,p = 0.02)。出院时的 NIHSS 也有同样的关联(NIHSS ⩽ 5:0.3 ± 0.5 L;NIHSS > 5:0.6 ± 0.6 L;p = 0.03)。mRS d90 转移分析表明,平均体液平衡为 p 的患者具有显著意义:血栓切除术后脑卒中患者在重症监护室的液体潴留与较差的功能和神经功能预后有关。因此,液体潴留成为干预后中风预后的另一个潜在预测因素。我们的研究结果初步表明,防止血管内血栓切除术后脑卒中患者出现过度液体潴留有利于功能和神经系统的恢复。因此,液体潴留可能是优化中风患者液体管理时需要考虑的一个因素。
