目的分析颈动脉斑块分布、性质及狭窄程度与脑梗死的相关关系。方法于2015年1月—2016年1月,在该院随机选取60例脑梗死患者(脑梗死组)和60例无脑梗死病史患者(对照组)。二组患者均行颈动脉多排螺旋CT血管成像,观察比较二组患者的颈动脉斑块分布、性质及狭窄程度。结果脑梗死组有47例患者检出各种类型的斑块共139处,其中软斑块45处(32.4%),钙化斑块28处(20.1%),混合斑块66处(47.5%),而对照组有18例患者检出各种类型的斑块共31处,其中软斑块4处(12.9%),钙化斑块19处(61.3%),混合斑块8处(25.8%),脑梗死组患者的斑块检出率明显高于对照组(P<0.05)。而二组患者斑块最好发部位均为颈总动脉,二组患者斑块分布情况无明显差异(P>0.05)。脑梗死组有42例患者发现颈动脉狭窄134处,其中轻度狭窄36处(26.9%),中度狭窄45处(33.6%),重度狭窄34处(25.4%),血管闭塞8例(6.0%),而对照组有11例患者发现动脉狭窄21处,其中轻度狭窄19处(90.5%),中度狭窄2处(9.5%),脑梗死组患者的颈动脉狭窄检出率明显高于对照组(P<0.05)。结论颈动脉斑块性质和颈动脉狭窄程度与脑梗死具有密切相关性。
Objective To analyze the relationship between carotid plaque distribution, nature and degree of stenosis and cerebral infarction. Methods From January 2015 to January 2016, 60 patients with cerebral infarction (cerebral infarction group) and 60 patients without cerebral infarction (control group) were randomly selected in the hospital. Two groups of patients underwent carotid multi-slice spiral CT angiography, compared the two groups of patients with carotid plaque distribution, nature and degree of stenosis. Results A total of 139 plaques were detected in 47 patients with cerebral infarction, including 45 soft plaque (32.4%), calcified plaque (20.1%), mixed plaque (66.5%), , While in the control group, there were 18 patients with 31 plaques of various types, including 4 soft plaque (12.9%), 19 calcified plaques (61.3%), 8 mixed plaques (25.8%), The detection rate of plaque in cerebral infarction group was significantly higher than that in control group (P <0.05). The two groups of patients with plaque were the best site of common carotid artery, two groups of patients with no significant difference in the distribution of plaque (P> 0.05). Among the 42 patients with cerebral infarction, there were 134 carotid stenosis, of which 36 were mild stenosis (26.9%), 45 were moderate stenosis (33.6%), 34 were severe stenosis (25.4%) and 8 were vascular occlusion %), While in the control group, there were 21 cases of arterial stenosis in 21 cases, of which 19 were mild stenosis (90.5%) and 2 were moderate stenosis (9.5%). The detection rate of carotid stenosis was significantly higher in patients with cerebral infarction In the control group (P <0.05). Conclusions Carotid plaque properties and carotid artery stenosis are closely related to cerebral infarction.
