Stroke:非明确来源性栓塞性脑卒中是哪来的,心房性心脏病还是非狭窄性大血管动脉斑块?

2020-03-17 shaosai MedSci原创

心房性心脏病和动脉粥样硬化性斑块性栓塞是非明确来源性栓塞性脑卒中(ESUS)的两种潜在性机制。目前对于ESUS患者中这两种机制的关系尚不明确。更好地明确两者之间的关系有助于针对性二次预防策略的制定。

背景和目的

心房性心脏病和动脉粥样硬化性斑块性栓塞是非明确来源性栓塞性脑卒中(ESUS)的两种潜在性机制。目前对于ESUS患者中这两种机制的关系尚不明确。更好地明确两者之间的关系有助于针对性二次预防策略的制定。

方法

本研究为NAVIGATE ESUS试验的子项目,该项目共纳入了7213例近期出现ESUS的患者。本研究纳入了患者左心房维度、脑梗死位置和颈动脉斑块数据。本研究主要变量为左心房直径和发生脑梗死同侧颈动脉斑块,次要变量为心房心脏病为房性早搏和新诊心房颤动。左心房扩大定义为直径≥4.7cm。调整年龄、性别、BMI、高血压、糖尿病、近期吸烟史和高血脂等指标后,利用多元logistics回归评价心房心脏病指标和同侧斑块的相关性。

结果

在3983例符合纳入标准的患者中,分别有235 (5.9%) 、939 (23.6%)例患者有左心房增大、同侧颈动脉斑块,共有94 (2.4%)例患者共存左心房扩大和同侧颈动脉斑块。共存左心房增大和同侧颈动脉斑块的危险指标为男性、白种人、高血压、吸烟史和冠状动脉粥样硬化性疾病。除了共存风险指标,经调整协变量后 (每厘米OR值, 1.1 [95% CI, 1.0-1.2]; P=0.08),左心房维度扩大与同侧颈动脉斑块并无相关性。在心房心脏病和同侧颈动脉斑块间也无相关性。

结论

在ESUS队列中,心房心脏病和颈动脉粥样硬化斑块间并无显著相关性,极少患者共存两种疾病。本研究表明,心房心脏病与颈动脉粥样硬化性斑块是ESUS患者相对独立的风险指标。

复合手术治疗症状性颅内动脉狭窄合并近端血管迂曲病变二例

颅内动脉粥样硬化性狭窄(intracranial atherosclerotic stenosis,ICAS)是导致缺血性卒中的重要原因,尤其好发于亚洲人群。在我国,33%~50%的卒中及50%以上的短暂性脑缺血发作患者存在ICAS。对于经过规范药物治疗仍有症状反复发作的ICAS患者,颅内动脉支架或血管成形术是安全、有效的治疗方式。然而,当ICAS合并近端颈动脉或椎动脉迂曲时,介入治疗的难度和风险

Stroke:无症状颈动脉狭窄**CEA?

如果近期无同侧颈动脉性缺血性卒中或TIA,我们通常把该侧颈动脉狭窄称为无症状颈动脉狭窄。无症状颈动脉狭窄的管理存在争论,争论点主要集中在无症状患者是否需要血运重建手术治疗,另外的争论点为应该选择何种血运重建手术。2014年AHA指南按照狭窄水平和血管的危险因素进行了推荐:对于围手术期卒中、心梗或死亡低风险的颈内动脉狭窄>70%的患者,推荐颈动脉内膜剥脱手术(CEA)。对于某些患者(血管造影>=60

Lancet Neurol:颅外椎动脉支架有获益的证据吗?

后循环卒中大约占急性缺血性卒中的20%,其中1/4卒中的病理生理机制为椎动脉或基底动脉狭窄。症状性椎动脉狭窄与卒中复发风险增加有关,特别是症状发作前几周。有人认为椎动脉支架能够降低这种风险。过去8年中,几项试验探讨了这个问题,虽然所有试验基本都是2期试验,样本量不足难以确定是否支架优于内科治疗。

Am J Neuroradiol:球囊颅内血管成形术的价值

SAMMPRIS研究发现内科治疗组30天卒中或死亡发生率为5.8%,而支架组为14.7%。因此,症状性颅内动脉狭窄的最佳治疗措施尚不清楚。很多专家一直探索是否某一些严重颅内动脉狭窄的患者能够从血管内治疗中获益。
