非狭窄性颈动脉斑块与前循环不明原因栓塞性卒中的相关性研究 Correlation of Non-Stenotic Carotid Plaque with Anterior Circulation Embolic Stroke of Undetermined Source

open access: yesZhongguo cuzhong zazhi, 2022
目的 探索同侧非狭窄性颈动脉粥样硬化斑块特征与前循环不明原因栓塞性卒中(embolic stroke of undetermined source,ESUS)的相关性。 方法 回顾性纳入北京市大兴区人民医院神经内科2017年1月-2022年5月连续住院的急性单侧前循环缺血性ESUS患者。采用颈动脉超声评估双侧非狭窄性颈动脉粥样硬化斑块,比较梗死同侧颈动脉与对侧颈动脉斑块的发生率、多发斑块的发生率、不均质回声斑块的比例以及颈动脉斑块厚度等特征的差异。 结果 共纳入101例ESUS患者,平均年龄60.7±

光学相干断层成像在颈内动脉系统中的应用进展 Application Progress of Optical Coherence Tomography in Internal Carotid Artery System

open access: yesZhongguo cuzhong zazhi, 2018
颈内动脉系统供应脑的前循环。颈内动脉粥样硬化、颈动脉血管炎以及颈内动脉夹层等病 变均会导致血管腔狭窄、斑块破裂及继发血栓的形成,继而引起缺血性脑血管病。本文介绍颈动脉 系统光学相干断层成像(optical coherence tomography, OCT)成像方法、OCT对颈动脉病变的评价方法 以及在颈动脉支架置入过程中的应用,并对OCT技术在颈动脉系统中的应用优劣势和前景进行展望。 Abstract: Internal carotid artery system supplies the

多排螺旋CT造影测量颈动脉壁厚度与超声测量内中膜厚度的比较

open access: yesZhongguo shiyan zhenduanxue, 2020
目的本研究旨在通过对比多排螺旋CTA测量颈动脉壁厚度与超声测量内中膜厚度的相关性,探讨颈部动脉CTA检查是否可以成为评估颈动脉内膜-中膜厚度的新方法。方法收集在我院行颈动脉超声检查及颈动脉CTA检查的老年患者39例。通过CT后处理技术进行颈动脉壁厚度评估,通过超声测量评估颈动脉内膜-中膜厚度,并评估两种方法的一致性。结果 CTA测量颈动脉壁厚度的范围为0.49mm-1.21mm,均值为(0.85±0.19)mm。超声测量内中膜厚度的范围为0.51mm-1.25mm,均值为(0.88±0.19)mm ...

Studies on relationship between blood pressure management and stroke in the China expert’s consensus on symptomatic intracranial atherosclerotic stenosis [PDF]

open access: yes
缺血性卒中的血压管理问题一直是颇有争议的临床问题,甚至不同的研究给出了相互矛盾的结果。随着近来坎地沙坦急性卒中试验(Candesartan Acute Stroke Trial, SCAST)和中国急性缺血性卒中的降压试验(China Antihypertensive Trial in Acute Ischemic Stroke, CATIS)等一些大型随机临床对照研究结果的问世,这个问题的方向似乎越来越明晰,但仍然有些令人费解的地方 ...

ApoE基因多态性与动脉粥样硬化性脑梗死的相关性研究 [PDF]

open access: yes, 2018
目的分析ApoE基因与血脂和颈动脉粥样硬化程度的关系,进一步探讨ApoE基因与动脉粥样硬化性脑梗死的相关性。方法采用病例-对照研究的方法,收集厦门大学附属第一医院神经内科的95例缺血性脑卒中和65例非缺血性脑卒中住院患者。检测患者的ApoE基因型、血脂及颈动脉粥样硬化程度。结果与E2/E3比较,基因型E3/E3、E3/E4可能是缺血性脑卒中的保护因素;缺血性和非缺血性脑卒中患者在血浆TC、LDL-C、ApoB含量比较上均为E3/E4> E3/E3>E2/E3,且2组血浆LDL-C浓度在E3/E4与E2 ...
