颈部血管超声在判断脑梗死患者血管狭窄程度以及其与脑梗死相关性中的研究价值

摘要

目的 研究应用颈部血管超声在判断脑梗死患者狭窄程度以及其与脑梗死发生的相关性。方法 选取我院2019年2月至2019年12月期间进行颈部血管超声检查的脑梗死患者50例作为本次研究的观察组，同期在本院健康体检行颈部血管超声检查的患者50例作为本次研究的对照组。比较两组患者颈动脉形态上的差异，并对颈动脉狭窄程度做出评价。结果 观察组患者检出动脉硬化斑块46个，对照组检出动脉硬化斑块8个，分别占16.9%和92.5%，脑梗死患者颈动脉粥样斑块发生率明显高于对照组，差异有显著性（P＜0.01）。两组患者在颈动脉无狭窄、中度狭窄和重度狭窄发生率方面和颈动脉粥样斑块改变方面具有显著性差异（P＜0.05）。但观察组和对照组患者在动脉轻度狭窄发生率上无统计学意义（P＞0.05）。结论 颈动脉狭窄与脑梗死的发生率呈正相关关系，釆用颈部血管超声及早发现并诊断颈动脉狭窄程度，对预防脑梗死的发生具有重要的临床指导意义。

Abstract

Objective To study the application of cervical vascular ultrasound in judging the degree of stenosis in patients with cerebral infarction and its correlation with the occurrence of cerebral infarction.
Methods A total of 50 patients with cerebral infarction who underwent cervical vascular ultrasound examination in our hospital from February 2019 to December 2019 were selected as the observation group of this study, and 50 patients who underwent cervical vascular ultrasound examination in our hospital during the same period were selected. as the control group for this study. The differences in carotid artery morphology were compared between the two groups, and the degree of carotid artery stenosis was evaluated.
Results There were 46 arteriosclerotic plaques detected in the observation group and 8 arteriosclerotic plaques in the control group, accounting for 16.9% and 92.5%, respectively. The incidence of carotid atherosclerotic plaques in patients with cerebral infarction was significantly higher than that in the control group. Significant (P<0.01). There were significant differences in the incidence of carotid artery no stenosis, moderate stenosis and severe stenosis, and carotid atherosclerotic plaque changes between the two groups (P<0.05). However, there was no statistical significance in the incidence of mild arterial stenosis between the observation group and the control group (P>0.05).
Conclusion   Carotid artery stenosis is positively correlated with the incidence of cerebral infarction. Early detection and diagnosis of carotid artery stenosis by cervical vascular ultrasound has important clinical significance for preventing the occurrence of cerebral infarction.
