摘要
目的 探讨不同类型脑梗死患者颈动脉超声的特点。方法 应用HDI 5 0 0 0彩色多普勒超声仪对 2 0 7例急性脑梗死患者进行了检测。按头颅CT或MRI结果分为单发组和多发组 ,按临床发病情况分为首发梗死组和复发梗死组 ,按病情程度分为轻型和中、重型组。分别对以上各组观察有无斑块形成、斑块积分、管腔狭窄程度和血流动力学的改变。结果 ①多发组颈动脉粥样硬化斑块发生率 (88.5 % )高于单发组 (72 .9% ,χ2 =8.2 88,P <0 .0 1) ,颈动脉狭窄的程度高于单发组 (χ2 =3.974 ,P <0 .0 5 ) ,多发组较单发组梗死侧颈总动脉内径增宽、内膜增厚、斑块积分值均高于单发组 ,收缩期峰值流速减小 ,血管阻力增加 (P <0 .0 5 ,P <0 .0 1)。②复发组颈动脉粥样硬化斑块形成发生率 (91.7% )高于首发组 (78.2 % ,χ2 =5 .2 39,P <0 .0 5 ) ,颈动脉狭窄程度与首发组比较没有统计学意义 ;复发组较首发组颈总动脉内径增宽、内膜增厚 ,血管阻力增加 (P <0 .0 1)。③轻型与中、重型脑梗死组比较 ,斑块发生率、斑块积分、梗死侧颈总动脉内径、内膜狭窄程度及血流动力学情况比较均无统计学意义。结论 多发性脑梗死、复发性脑梗死颈动脉粥样硬化斑块发生率高 ,程度重 ,与颈动脉粥样硬化关系更加密切。
Objective To study the ultrasound character of carotid artery in different types of cerebral infarction patients.Methods 207 patients with acute cerebral infarction were studied by using HDI-5000 Color Doppler Ultrasound.Cerebral infarction patients were separated into single infarction group and multiple infarction group by CT or MRI; They also were separated into first time infarction and several time infarction by clinical feature and slight type,middle type and severe type by the extent of disease.The plaque?severity of artery stenosis,hemodynamics of carotid and vertebral arteries were observed in the above groups.Results ① The prevalence of carotid atherosclerosis plaque was higher in multi-occurring group( 88.5%) than in single-occurring one( 72.9%,P< 0.01).The servity of artery stenosis was higher in multi-occurring group than in single-occurring group (P< 0.05).The lumen diameter of common carotid artery (CCA) became wider and intima-media thickness of CCA became thicker in multi-occurring group than in single-occurring group.The plaque score was higher in patients with multi-occurring than single-occurring.The peak systolic velocity (PSV) of carotid artery was decreased and the resistance index (RI) of carotid artery was increased(P< 0.01).② The prevalence of carotid atherosclerosis plaque was higher in patients with cerebral infarction several times( 91.7%)than those who had the disease first time( 78.2%,P< 0.05).There is no significant difference of the severity of artery stenosis in cerebral infarction patients with first and several times.The lumen diameter of CCA became wider and intima-midea thickness of CCA became thicker and RI of carotid artery was increased more in patients with cerebral infarction several times than those who had the disease first time.③ There is no significant difference of the occurrence rate of carotid atherosclerosis plaque,the lumen diameter,intimal-medial thickness,plaque,severity of artery stenosis and hemodynamics of carotid and vertebral arteries in cerebral infarction patients with mild,middle and severe type.Conclusion The prevalence of carotid atheroscierosis plague was high and the severity of carotid atheroscierosis prominent in patients with multi-occurring and patients with cerebral infarction several times.There is a close relationship with carotid atherosclerosis with multi-occurring cerebral infarction and several times infarction.
