MSCT冠状动脉成像在诊断心肌桥-壁冠状动脉的临床价值

Clinical Value of 128-slice Spiral CT Coronary Angiography in the Diagnosis of Myocardial Bridge-mural Coronary Arteries

目的探讨128层螺旋CT冠状动脉成像在诊断心肌桥-壁冠状动脉中的临床应用价值。方法回顾性分析2012年4月-2014年6月本院临床怀疑冠心病患者行128层螺旋CT冠状动脉成像检查154例,对所有影像资料进行汇总分析。结果在154例研究对象中发现50例(57处)心肌桥-壁冠状动脉(占32.47%)。壁冠状动脉的平均长度(20.15±8.20)mm,其中浅表型37处(64.90%),深厚型20处(35.10%)。于心肌桥的近心端发现粥样斑块21例。结论 128层螺旋CT冠状动脉成像清晰,在显示心肌桥-壁冠状动脉的定位、长度、狭窄程度、心肌桥的厚度、近端血管有无粥样硬化斑块等方面具有显著优势,为临床诊断心肌桥相关的冠状动脉病变提供可靠的影像学依据。

Objective To investigate the clinical value of 128-slice spiral CT coronary angiography in the diagnosis of myocardial bridge-mural of coronary. MethodsRetrospective analysis the data of 154 cases of clinical suspected coronary artery disease from April 2012 to June 2014. Results The study found that 50 cases（57）existed myocardial bridge-mural coronary artery（discovery rate of 32.47%） in 154 patients. The average length of mural coronary artery was（20.15±8.20）mm. Of myocardial bridge： superficial type in 37 cases（64.90%）, deep type in 20 cases（35.10%）. The proximal end of myocardial bridge plaques found in 21 cases. Conclusiononclusion 128-slice CT coronary angiography has a significant advantage in diagnosing myocardial bridge-mural coronary artery, especially in the location, length, degree of coronary artery stenosis, myocardial bridge thickness, presence or absence of proximal vessel coronary plaques, which provides reliable imaging data for clinical doctor.
