MSCT检查CTA技术对心肌桥-壁冠状动脉的诊断价值探讨

Diagnostic Value of MSTA Examination CTA Technology for Myocardial Bridge-Mural Coronary

目的探讨MSCT检查CTA技术对MB-MCA的诊断价值。方法选取本院2017年3月至2019年8月收治的167例行MSCTA检查的受检者作为研究对象(受检者中包括健康人群和MB-MCA患者),将其MSCTA检查的诊断结果进行讨论;分析MSCTA检查不同分支的MB-MCA的检出率及MB不同狭窄程度的厚度与长度。结果167例受检者中,经MSCTA检出58例患者为MB-MCA,检出率为34.73%,其中发生于左冠状动脉前降支及其分支25例,第一对角支7例,第二对角支5例,右冠状动脉及其分支9例,钝缘支5例,回旋支3例,多支病变4例。MB轻度狭窄患者19例,MB厚度为(0.47±0.59)mm,长度为(21.78±12.47)mm;中度狭窄患者21例,MB厚度为(2.07±1.09)mm,长度为(25.44±7.65)mm;重度狭窄患者18例,MB厚度为(3.19±1.14)mm,长度为(116.84±10.65)mm。结论MSCTA检查可清楚显示MB-MCA的影像学特点,在早期诊断MB-MCA上安全可靠,具有一定的价值,结合患者临床资料可有效提高诊断准确率,值得临床推广。

Objective To explore the diagnostic value of MSTA examination CTA technology for Mb-MCA.Methods 167 patients underwent MSCTA examinations from March 2017 to August 2019 in our hospital were selected as subjects(including healthy subjects and Mb-MCA patients),and the diagnosis results of MSCTA examinations were discussed.The detection rate of Mb-MCA and the thickness and length of Mb with different degrees of stenosis by different branches of MSCTA were analyzed.Results Among the 167 subjects,58 patients were detected by MSCTA with Mb-MCA,and the detection rate was 34.73%.Among them,25 cases occurred in the left anterior descending of coronary artery and its branches,7 cases occurred in the first diagonal branch,5 cases occurred in the second diagonal branch,9 cases occurred in the right coronary artery and its branch,5 cases occurred in the obtuse marginal branch,3 cases occurred in left circumflex,5 cases occurred in multivessel lesions.There were 19 patients with mild stenosis of Mb,Mb thickness was(0.47±0.59)mm,length was(21.78±12.47)mm,and there were 21 patients with moderate stenosis,Mb thickness was(2.07±1.09)mm,length was(25.44±7.65)mm,and there were 18 patients with severe stenosis,Mb thickness(3.19±1.14)mm,length(116.84±10.65)mm.Conclusion MSCTA examination can clearly show that the imaging characteristics of Mb-MCA.It is safe and reliable in the early diagnosis of Mb-MCA and has a specific value.Combining the clinical data of patients can effectively improve diagnostic accuracy.It is worthy of clinical promotion.
