目的：探讨颈动脉粥样硬化斑块、狭窄与脑梗死的关系。方法回顾性分析56例脑梗死患者(梗死组)和49例无脑卒中病史(对照组)的颈动脉 CT 血管造影(CTA)，比较2组间的颈动脉斑块分布、性质及颈动脉狭窄程度差异。结果脑梗死组患者中42例共检出各种类型斑块126处，其中软斑块39处，钙化斑块34处，混合斑块53处，软斑块和混合斑块约占73%；42例患者中发现溃疡斑块7例；其中斑块最好发部位为颈总动脉分叉处；38例可见动脉狭窄102处，轻度狭窄29处，中度狭窄40处，重度狭窄27处，中重度狭窄约占65.7%，血管闭塞6例。对照组共11例患者检出各种类型斑块28处，其中软斑块6处，钙化斑块13处，混合斑块9处；7例颈动脉轻度狭窄10处，中度狭窄1处。颈动脉斑块和狭窄2组间比较差异均有统计学意义(P <0.05)。结论颈动脉斑块及狭窄是脑梗死的重要危险因素。CTA 在分析、评价缺血性脑卒中患者颈动脉狭窄及粥样斑块方面具有重要的临床价值。

Objective To investigate the relationship between carotid arteriostenosis and atheromatous plaques with cerebral in-farction.Methods Cervical spiral CT angiography of 56 cases with cerebral infarction and 49 cases without cerebral infarction were retrospectively analysed .The difference between the two groups was compared with regard to the distribution ,nature of plaques and the degree of carotid artery stenosis.Results Of 56 patients with cerebral infarction,126 atheromatous plaques were detected in 42 patients,of which 39 were soft,34 were calcified,53 exhibited a combined nature of both calcified and soft plaque and 7 cases were plaque ulcerations (soft plaque and mixed plaque accounted for about 73%).Plaque location for carotid artery was in the bifurcation. 102 carotid arteries stenosis were found in 38 patients,which included mild stenosis in 29,moderate in 40,severe in 27 and occlusion in 6(moderate and severe stenosis accounted for about 65.7%).In the control group,28 plaques were detected in 1 1 cases,of which 6 were soft,13 were calcified and 9 exhibited a combined nature of both calcified and soft plaque.1 1 carotid arteries stenosis were found in 7 patients,included mild stenosis in 10,moderate in 1.A significant difference (P <0.05)in carotid arteriostenosis and ath-eromatous plaques between the two groups was found.Conclusion Carotid plaques and stenosis are important risk factors of cerebral infarction.Multi-slice spiral CT angiography(MSCTA)has important value in analysis of carotid artery stenosis and atheroderotic plaques.
