JAMA子刊:警惕!年纪轻轻就卒中了?小心被忽视的颈动脉网!

2021-06-03 MedSci原创 MedSci原创

颈动脉网可能是未被识别的卒中危险因素之一。

2016年,一项发表于《神经病学》Neurology杂志上的病例对照研究显示,在病因不明的年轻卒中患者中,颈动脉网(CW)与缺血性卒中在统计学上存在显著相关关系。这一研究引起了大家的注意。

颈动脉网是指从颈动脉壁突出的延伸至动脉腔内的薄膜样片状物,通常位于颈动脉起始部。“颈动脉网可能是一个未被重视的卒中危险因素。”主要作者Daniel M. Mandell表示,“利用常规血管影像检查(CTA或MRA)诊断颈动脉网相对比较容易。”

在CTA图像中不同CW的影像学证据

“但相比动脉粥样硬化斑块,颈动脉网常因其看似无害而被临床医生所忽视。但问题是这看似无害的颈动脉网是血栓栓塞的来源,可能是缺血性卒中的一个未被识别的危险因素。” Mandell表示。

随后,又有陆续一些研究表明,有症状的CW患者有复发卒中的高风险,但缺乏高质量的数据。为了评估有症状的CW患者2年内复发卒中的风险,来自荷兰阿姆斯特丹大学神经病学专家开展了相关的研究,结果发表在JAMA Neurology杂志上。

该项比较性队列研究使用了来自MR CLEAN试验(2010-2014年)和MR CLEAN登记处(2014-2017年)的数据,后两者是在荷兰进行的关于大血管闭塞(LVO)卒中血管内治疗(EVT)的全国性前瞻性多中心研究。基线数据来自3439名连续的前循环LVO卒中成年患者,并有颈动脉的CTA血管成像。

两位神经放射学专家评估了CTA图像,以确定是否存在CW,并确定了30名与存在中风的CW患者。将这30名有CW的患者与168名参加MR CLEAN扩展随访试验的无CW患者进行比较,后者被随机分配到EVT组。主要结果指标是有症状卒中后2年内发生的复发卒中。

一例隐源性卒中患者颈动脉网图像:轴位 CTA以及局部放大图(A)显示颈动脉腔内薄膜样结构;矢状位 CTA(B)显示动脉内模样片状结构,与颈动脉网描述一致。

结果显示,在3439名基线CTA评估的患者中,中位年龄为72岁1813名(53%)为男性。与没有CW的患者相比,CW患者更年轻(中位年龄,57[46-66]岁 vs 66[56-77]岁)且女性比例更高(22/30 [73%] vs 67/168 [40%])。

其中,30名患者中有28名(93%)在发生卒中后接受了治疗(23名接受了抗血小板治疗,5名接受了抗凝血治疗)。在2年的随访中,两组患者均有5名(17% vs 3%)复发卒中。但CW患者卒中复发的风险为非CW患者的近5倍(RR=4.9;95%CI,1.4-18.1)!

部分卒中患者的相关信息

研究人员指出,6名有症状的CW患者中,有1名在2年内复发了卒中,这表明仅靠医疗管理可能无法为CW患者提供足够的保护。

综上,在原因未明的卒中患者中,颈动脉网与缺血性卒中之间存在相关性。颈动脉网可能是未被识别的卒中危险因素之一。
