摘要
目的：探讨VCT冠状动脉成像对壁冠状动脉的诊断价值。方法：121例可疑冠心病患者行VCT冠状动脉成像，回顾性分析VCT确诊的33例壁冠状动脉的CTA表现。结果：33例共59段壁冠状动脉，发生率为27%。其中前降支占40%，对角支和钝缘支分别占27%和22.3%，回旋支为6.7%，右冠（后降支）5.0%。壁冠状动脉长度为5～49mm，平均（22±11）mm，心肌桥深度为1.2～5mm，平均（2.3±1.0）mm。CTA表现为壁冠状动脉轻度平直，管腔光滑，未见明显狭窄，两端亦未见软硬斑块。结论：64排VCT是确诊壁冠状动脉的首选方法，但不能评价其收缩期的血流变化。壁冠状动脉与动脉硬化无明显关系。有典型心绞痛症状和心电图改变的心肌桥患者，应及时接受CAG检查。
Abstract
Objective: To study the clinical value of VCT coronary artery imaging in the diagnosis of myocardial bridges. Methods: A total of 121 cases with clinical appearance of coronary disease underwent the examination of VCT, the appearance of myocardial bridges diagnosed by VCT in 33 cases were analysed retrospectively. Results: Fifty-nine myocardial bridges were found in 33 patients, the rate was 27%. The location in left anterior descending artery was 40%, diagonal artery 27%, left obtuse marginal branch 22.3%, left circumflex artery 6.7%, right coronary artery 5%. Length of myocardial bridges was 5～49mm, average (22±11)mm, depth was 1.2～5mm, average (2.3±1.0)mm. The appearance of myocardial bridge in CT angiography was slightly flat, but the lumen was smooth, with no stenosis and plaque. Conclusion: VCT is the first choice in the diagnosis of myocardial bridge, but can not evaluate the blood flow. There is no relationship between myocardial bridge and arteriosclerosis. When the patient with myocardial bridge has the symptom of typical angina and the ECG change occurring, the examination of coronary artery angiography should be accepted.
