高频超声对脑梗死患者颈股动脉解剖结构变化的研究

目的:应用高频超声观察脑梗死患者颈动脉(CA)、股动脉(FA)解剖及结构变化、内-中膜厚度(IMT)、斑块数目、回声,以探讨脑梗死与CA、FA硬化的相互关系。方法:对50例脑梗死患者和40例健康老年人CA、FA行高频超声检查,观察颈、股动脉内-中膜有无增厚、有无斑块、斑块数目和回声情况。结果:脑梗死组CAIMT为(0.70±0.13)mm,明显大于对照组(0.56±0.11)mm,(P<0.05);FAIMT(0.72±0.14)mm,明显大于对照组(0.59±0.09)mm,(P<0.05);脑梗死组CA、FA斑块发生率高于对照组(P<0.05)。结论:高频超声是无创诊断早期动脉硬化(AS)的简便有效方法,应用外周大血管的解剖结构变化可间接评价全身动脉硬化程度。为临床预防脑血管疾病提供帮助。

High-Frequency Ultrasound Assessment of Carotid Femoral Artery Anatomic Structure in Patients with Cerebral Infarction

Objective To study the changes(including intima- media thickness,echo and numbers of plaque) of the anatomic structureof carotid artery(CA)、femoral artery(FA) in patients to assessment the relation between sclerosis of CA and FA and erebral infarction utilizing high-frequency ultrasound.Methods CA and FA in fifty patients and forty healthy adults were examined with bigh-frequency ultrasound.We measured intima-media thickness(IMT)and observedthe echo of the intima-media,the echo and number of plaque. Results IMT measurements of the CA(0.70±0.13) mm and FA(0.72±0.14) mm were greater in persons with cerebral infarction than those without CA(0.56±0.11) mm,FA(0.59±0.09)mmP<0.05).The plaque of CA and FA in the cerebral infarction group increased than the control(P<0.05). Conclusions High-Frequency ultrasound could effectively and noninvasively measured arteriosclerosis.With measuring peripheral vessels changes indirectly ssess sclerosis of blood vessels of the whole body,according to which make clinical diagnosis.
