摘要
目的:探讨心肌桥的多排螺旋CT血管造影成像特点及与冠状动脉粥样硬化之间的关系。方法:对92名患者进行CT冠状动脉血管造影及图像后处理(最大密度投影、曲面重组、容积重组),分析其影像改变及特点;并分析左前降支肌桥与冠状动脉粥样硬化发生关系。结果:92例病例共检出心肌桥23例,检出率25%。其中左前降支中段18例,占78.2%;临近心肌桥段冠状动脉与无心肌桥相同部位冠状动脉斑块的发生存在统计学意义(P<0.05)。结论:螺旋CT血管造影是诊断心肌桥的有效且无创的方法之一;心肌桥为冠状动脉粥样硬化发生的重要因素。
Objective： To analysis the CTA characteristics of myocardial bridge and the relationship with coronary artery atherosclerosis. Methods： 92 patients undergone CT angiography （CTA） were reviewed for this study and MIP, CPR, VR were performed and study. Further, analyzed the relationship between myocardial bridge and atherosclerosis in LAD. Results： 23 patients with myocardial bridge were found in all 92 patients （25 %）, 18 in LAD （78.2%）. The difference of atherosclerosis prevalence between the proximal coronary artery with myocardial bridge group and no myocardial bridge group showed a statistical significant （P0.05）. Conclusion： MSCT coronary angiography is an accurate and non-invasive method in diagnosing myocardial bridge. Myocardial bridge is a important reason of coronary artery atherosclerosis.
