高频超声对脑梗死患者颈股动脉解剖结构变化的研究

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

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。

Objective To study the changes（including intimamedia 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）mm P〈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.
