摘要
目的探讨多排螺旋CT(Multi-slice Spiral CT,MSCT)冠状动脉成像对壁冠状动脉-心肌桥(myocardial bridges,MBs)的诊断价值。方法收集2005年7月～2008年7月285例在我院同时接受MSCT和冠状动脉造影(coronary angiography,CAG)检查患者的影像资料,分析确诊的壁冠状动脉的影像表现,进行准确率的对比。结果在285例患者中,MSCT检出MBs59例存在82段壁冠状动脉,检出率20.7%。CAG检出16例,检出率5.6%。MSCT检出59例患者的82处MB,单支血管者42处,占71.19%。其他为2支或3支血管复合存在。壁冠状动脉在左前降支(LAD)者67处(占81.71%,近中段52处,远段15处)。左回旋支(LCX)远段者4处(4.87%),钝缘支(OM)远段者2处,对角支(D1+D2)远段4处,右冠状动脉中远段5处。MSCT结果中有26支与CAG发现的心肌桥(28支)一致,以CAG为检测心肌桥的"金标准",那么MSCT的敏感性为92.86%。结论多排螺旋CT血管造影能准确显示壁冠状动脉与心肌的解剖关系,是确诊壁冠状动脉的首选方法之一。
Objective To evaluate the clinical value of Multi slice Spiral CT（MSCT） and coronary artery imaging in diagnosing coronary artery myocardial bridges （MBs）. Methods Image data of 285 patients from July 2005 to July 2008 who accepted both the MSCT and coronary angiography CAG at our hospital were collected. Diagnostic performance of the two methods were analysed and the diagnostic accuracy were compared. Results In 285 cases of patients with MSCT examinations, 82 coronary artery were diagnosed in 59 cases, the detection rate of which was 20. 7%. In contrast, 16 cases were diagnosed by CAG and the detection rate was 5.6% In the 82 coronary artery diagnosed by MSCT, 42 coronary artery were single vessel, the proportion was 71.19%. Others were two vessels or three vessels. There were 67 in left anterior descending artery （LAD） ,in which 52 were near the middle and 15 were distal. 26 MBs diagnosed by MSCT were included in the 28 MBs diagnosed by CAG. Put CAG as the gold standard of myocardial bridge detecting, then MSCT＇s sensitivity was 92.86 %. Conclusion MSCT coronary artery imaging can accurately show the anatomical relationship between coronary artery and myocardial and it is one of the preferred method of diagnosing coronary artery.
