| ［摘要］ 目的 探讨128层螺旋CT冠状动脉血管成像（CTA）诊断心肌桥（MB）及其相关冠状动脉病变的临床价值。方法 回顾性分析该院2015-01～2015-12间300例行冠状动脉CTA检查患者的影像及临床资料，对MB的检出率、MB的厚度、壁冠状动脉（MCA）管腔狭窄程度、MB相关冠状动脉粥样硬化斑块进行评估分析。结果 300例患者中92例（107处）存在MB-MCA，纵深型MB厚度约为（3.15±1.12）mm。MCA管腔狭窄情况：舒张期MCA轻度狭窄22例，中度狭窄8例；收缩期MCA管腔轻度狭窄75例，管腔中度狭窄15例，重度狭窄6例。107处MCA近端发现冠状动脉粥样斑块46例，其中近端血管管腔轻度狭窄37例，中度狭窄6例，重度狭窄3例。结论 128层螺旋CT冠状动脉成像具有无创性，可以准确测量MB的厚度，通过多期重建对MCA管腔狭窄进行评价，对MB相关的冠状动脉粥样硬化斑块进行分析，为临床下一步检查及治疗方案选择提供更多信息。 |

| Abstract: |
| ［Abstract］ Objective To evaluate the clinical value of 128 slice spiral CT coronary angiography(CTA) in the diagnosis of myocardial bridge(MB) and its related coronary artery disease.Methods The clinical data and coronary CTA images of 300 cases in our hospital from January 2015 to December 2015 were analyzed to evaluate the detection rate and the thickness of the MB, degree of mural coronary artery(MCA) stenosis and coronary atherosclerotic plaque related MB.Results MB-MCA was found in 92 cases(107 parts), with the thickness of the deep type of MB-MCA being about （3.15±1.12）mm. During diastole, mild stenosis of MCA occurred in 22 cases and moderate stenosis in 8 cases. During systolic, mild stenosis of MCA occurred in 75 cases, moderate stenosis in 15 cases and severe stenosis in 6 cases. The proximal coronary artery atherosclerotic plaques were found in 46 cases of 107 affected parts, of which mild stenosis of proximal vascular lumen occurred in 37 cases, moderate stenosis in 6 cases and severe stenosis in 3 cases.Conclusion 128 slice spiral CT coronary artery imaging is non-invasive and can accurately measure the thickness of MB, evaluate MCA stenosis with the multi-stage reconstruction, analyze the coronary atherosclerotic plaques related to MB, and provide more information for clinical examination and treatment. |
