摘　　要：目的探讨螺旋CT血管造影(CTA)诊断心肌桥-壁冠状动脉(MB-MCA)血管形态学的价值。方法200例疑似MB-MCA患者均进行CTA和冠状动脉造影(CAG)检查,分析CTA技术对MB-MCA的诊断价值,对比CTA与CAG对浅在型、深在型MB-MCA心肌桥长度、壁冠脉狭窄程度的检查结果。结果CTA诊断MB-MCA的灵敏度为98.14%,特异度为89.74%,准确率为96.50%。CTA显示的浅在型与深在型MB-MCA患者的心肌桥长度均高于CAG(P<0.05),但CTA和CAG的壁冠脉狭窄程度比较,差异均无统计学意义(P>0.05)。结论CTA诊断MB-MCA的灵敏度、特异度及准确率均较高,能够从多个角度对壁冠脉血管、管腔形态以及结构进行观察,明确心肌桥长度、壁冠脉狭窄程度等指标。Objective To explore the value of spiral CT angiography(CTA)in the Diagnosis of vascular morphology of myocardial bridge-mural coronary artery(MB-MCA).Methods CTA and coronary angiography(CAG)were performed in 200 patients with suspected MB-MCA.The diagnostic value of CTA technology for MB-MCA was analyzed.The detection results of CTA and CAG on the length of myocardial bridge and the stenosis degree of mural coronary artery in superficial and deep MB-MCA were compared.Results The sensitivity,specificity and accuracy of CTA in the diagnosis of MB-MCA were 98.14%,89.74%and 96.50%,respectively.The lengths of myocardial bridge of patients with superficial MB-MCA and deep MB-MCA showed by CTA were higher than those by CAG(P<0.05),while no statistical difference was found in the stenosis degree of mural coronary artery between CTA and CAG(P>0.05).Conclusions CTA in the diagnosis of MB-MCA has high sensitivity,specificity and accuracy,which can observe the mural coronary artery,lumen morphology and structure from multiple angles,and clarify the length of myocardial bridge and the stenosis degree of mural coronary artery.
