摘要

简介:自发性脑内出血(ICH)的几种早期非对比 CT(NCCT)征象可预测血肿扩大(HE)。然而,对于潜在的脑小血管疾病(SVD)与早期 NCCT 征象和 HE 之间的关联却探讨较少:我们对 2016 年至 2020 年期间在卒中中心接受随访成像的所有自发性脑室上 ICH 患者进行了分析。早期 NCCT 征象分为形状征象和密度征象。HE定义为血肿体积比基线增加≥6 mL或33%。SVD的严重程度由基于CT的3点和基于磁共振成像(MRI)的4点SVD评分来评估。回归模型用于研究 SVD 评分与血肿体积、NCCT 征象和 HE 之间的关系:共纳入 328 名患者(中位年龄:64 岁;38% 为女性)。基线 ICH 容量中位数为 8.6 mL,38% 的患者在最初的 NCCT 上有形状征象,52% 的患者有密度征象。MRI-SVD 评分越高,ICH 容量越小(p = 0.0006),形状征(p = 0.001)或密度征(p = 0.0003)越少。总体而言,16% 的患者出现了 HE。较高的 MRI-SVD 评分与 HE 成反比(调整后的几率比 0.71,95% CI:0.53-0.96)。亚组分析显示,这种关联主要出现在年龄较小(65 岁)、男性、深部出血或不符合脑淀粉样血管病诊断标准的患者身上:在自发性 ICH 患者中,较严重的 SVD 与较小的血肿体积、较少的 NCCT 征象和较低的 HE 风险相关。为什么严重病变的脑小血管负担越重,出血越少,这还需要进一步研究。

Associations of Cerebral Small Vessel Disease on the Features of Hematoma and Hematoma Expansion in Intracerebral Hemorrhage.

Introduction: Several early noncontrast CT (NCCT) signs of spontaneous intracerebral hemorrhage (ICH) can predict hematoma expansion (HE). However, the associations of underlying cerebral small vessel disease (SVD) on early NCCT signs and HE have been less explored.

Methods: We conducted an analysis of all patients with spontaneous supratentorial ICH and received follow-up imaging between 2016 and 2020 at a stroke center. The early NCCT signs were categorized as shape or density signs. HE was defined as an increase in hematoma volume ≥6 mL or 33% from baseline. The severity of SVD was assessed by both a 3-point CT-based and a 4-point magnetic resonance imaging (MRI)-based SVD score. Regression models were used to examine the associations between SVD score and hematoma volume, NCCT signs, and HE.

Results: A total of 328 patients (median age: 64 years; 38% female) were included. The median baseline ICH volume was 8.6 mL, with 38% of the patients had shape signs and 52% had density signs on the initial NCCT. Higher MRI-SVD scores were associated with smaller ICH volumes (p = 0.0006), fewer shape (p = 0.001), or density signs (p = 0.0003). Overall, 16% of patients experienced HE. A higher MRI-SVD score was inversely associated with HE (adjusted odds ratio 0.71, 95% CI: 0.53-0.96). Subgroup analysis revealed that this association was primarily observed in patients who were younger (<65 years), male, had deep hemorrhage, or did not meet the criteria for cerebral amyloid angiopathy diagnosis.

Conclusions: In patients with spontaneous ICH, a more severe SVD was associated with smaller hematoma volume, fewer NCCT signs, and a lower risk of HE. Further research is required to investigate why a higher burden of severely diseased cerebral small blood vessels is associated with less bleeding.

期刊介绍: A rapidly-growing field, stroke and cerebrovascular research is unique in that it involves a variety of specialties such as neurology, internal medicine, surgery, radiology, epidemiology, cardiology, hematology, psychology and rehabilitation. ''Cerebrovascular Diseases'' is an international forum which meets the growing need for sophisticated, up-to-date scientific information on clinical data, diagnostic testing, and therapeutic issues, dealing with all aspects of stroke and cerebrovascular diseases. It contains original contributions, reviews of selected topics and clinical investigative studies, recent meeting reports and work-in-progress as well as discussions on controversial issues. All aspects related to clinical advances are considered, while purely experimental work appears if directly relevant to clinical issues.
