64排螺旋CT冠状动脉造影在壁冠状动脉检测中的价值

Evaluation of 64-slice spiral CT coronary angiography in the detection of mural coronary artery

目的研究壁冠状动脉患者采用64排螺旋CT冠状动脉造影检测的临床诊断价值。方法临床纳入49例我院2015年8月～2017年8月期间收治疑似冠心病的患者作为研究对象,所有患者均进行64排螺旋CT冠状动脉造影检查,进行冠状动脉曲面重建并进行分析,观察64排螺旋CT冠状动脉造影检查对壁冠状动脉的诊断价值。结果 49例患者进行64排螺旋CT检查有21例存在壁冠状动脉,其中发生于前降支及其分支患者13例,发生于右冠状动脉及其分支患者3例,剩余5例患者为多支病变。结论 64排螺旋CT冠状动脉造影对壁冠状动脉的诊断率较高,对心肌桥的长度、厚度检出率较高,具有无创优势,值得临床应用及推广。

Objective To study the clinical value of 64-slice spiral CT coronary angiography in the detection of mural coronary artery.Methods 49 patients with suspected coronary heart diseases hospitalized in our hospital from August 2015 to August2017 were included. 64-slice spiral CT coronary angiography was performed on all cases to conduct the curved planar reformation（CPR） of coronary artery, and the examination results were analyzed. Results Coronary angiography findings showed that there were 21 cases with mural coronary artery, wherein there were 13 cases in the anterior descending branch and its branches, 3 cases in the right coronary artery and its branches and 5 cases of multi-vessel lesion. Conclusion The 64-slice spiral CT coronary angiography has a higher detection rate of the mural coronary artery and the length and thickness of myocardial bridge, and is a non-invasive imaging modality, thus worthy of clinical application and promotion.
