Abstract

Background and purpose: In wake-up stroke, CT-based quantitative net water uptake (NWU) might serve as an alternative tool to MRI to guide intravenous thrombolysis with alteplase (IVT). An important complication after IVT is symptomatic intracerebral haemorrhage (sICH). As NWU directly implies ischaemic lesion progression, reflecting blood-brain barrier injury, we hypothesised that NWU predicts sICH in patients who had a ischaemic stroke undergoing thrombectomy with unknown onset.

Methods: Consecutive analysis of all patients who had unknown onset anterior circulation ischaemic stroke who underwent CT at baseline and endovascular treatment between December 2016 and October 2020. Quantitative NWU was assessed on baseline CT. The primary endpoint was sICH. The association of NWU and other baseline parameters to sICH was investigated using inverse-probability weighting (IPW) analysis.

Results: A total of 88 patients were included, of which 46 patients (52.3%) received IVT. The median NWU was 10.7% (IQR: 5.1-17.7). The proportion of patients with any haemorrhage and sICH were 35.2% and 13.6%. NWU at baseline was significantly higher in patients with sICH (19.1% vs 9.6%, p<0.0001) and the median Alberta Stroke Program Early CT Score (ASPECTS) was lower (5 vs 8, p<0.0001). Following IPW, there was no association between IVT and sICH in unadjusted analysis. However, after adjusting for ASPECTS and NWU, there was a significant association between IVT administration and sICH (14.6%, 95% CI: 3.3% to 25.6%, p<0.01).

Conclusion: In patients with ischaemic stroke with unknown onset, the combination of high NWU with IVT is directly linked to higher rates of sICH. Besides ASPECTS for evaluating the extent of the early infarct lesion, quantitative NWU could be used as an imaging biomarker to assess the degree of blood-brain barrier damage in order to predict the risk of sICH in patients with wake up stroke.

不明原因脑卒中辅助溶栓的血栓切除术后出血取决于早期病变的高摄水率。
背景和目的:在脑卒中清醒状态下,基于 CT 的定量净摄取水量(NWU)可作为 MRI 的替代工具,指导阿替普酶静脉溶栓(IVT)。静脉溶栓后的一个重要并发症是无症状性脑内出血(sICH)。由于NWU直接意味着缺血性病变的进展,反映了血脑屏障损伤,因此我们假设NWU能预测接受血栓切除术的缺血性中风患者的sICH:方法:对2016年12月至2020年10月期间接受CT基线检查和血管内治疗的所有发病不明的前循环缺血性卒中患者进行连续分析。基线 CT 评估了定量 NWU。主要终点为 sICH。采用反概率加权(IPW)分析法研究了NWU和其他基线参数与sICH的关系:结果:共纳入88名患者,其中46名患者(52.3%)接受了IVT治疗。NWU中位数为10.7%(IQR:5.1-17.7)。任何出血和 sICH 患者的比例分别为 35.2% 和 13.6%。sICH 患者的基线 NWU 明显更高(19.1% vs 9.6%,p 结论:在发病原因不明的缺血性卒中患者中,高 NWU 与 IVT 的组合与较高的 sICH 发生率直接相关。除了 ASPECTS 可用于评估早期梗死病灶的范围外,定量 NWU 也可作为一种影像生物标志物,用于评估血脑屏障的损伤程度,以预测清醒脑卒中患者发生 sICH 的风险。
