摘要
目的探讨西门子双源CT冠状动脉成像对单冠畸形的诊断价值。方法双盲法分析58例单冠畸形患者CTA图像,对其分型,并计算构成比。以心电图心肌缺血改变或典型不稳定心绞痛为标准(排除冠状动脉严重狭窄的患者),比较ⅡB型与其他单冠畸形发生心肌缺血的概率,卡方检验验证二者的差异性,P<0.05为差异有统计学意义。结果LⅠ型发生率最高。排除冠状动脉严重狭窄患者,余48例(ⅡB型9例,其他39例),有心肌缺血者16例,其中ⅡB型6例(66.7%),其他10例(25.6%)。ⅡB型发生心肌缺血概率较高,二者差异有统计学意义(χ^(2)=5.538,P=0.019)。结论西门子双源CT冠状动脉成像可准确观察单冠畸形的起源、走行,并准确分型,可作为单冠畸形患者的首选检查。
Objective To explore the diagnostic value of Siemens dual-source CT coronary angiography for single coronary artery.Methods Double-blind method was used to analyze the CTA images of 58 patients with single coronaryartery,to classify them,and to calculate the composition ratio.Taking electrocardiogram myocardial ischemic changes or typical unstable angina as the standard(excluding patients with severe coronary stenosis),comparing the probability of myocardial ischemia between typeⅡB and other single coronary artery,thechi-square test verified the difference between the two,P<0.05 is different.Results Type LⅠhas the highest incidence.Excluding patients with severe coronary stenosis,the remaining 48 cases(9 cases of typeⅡB,39 others),16 cases of myocardial ischemia,6 cases of typeⅡB(66.67%),and other 10 cases(25.64%),typeⅡB has a higher probability of myocardial ischemia,and there is a statistical difference between the two(χ^(2)=5.538,P=0.019).Conclusion Siemens dual-source CT Coronary angiography can accurately observe the origin and course of single coronary artery,and accurately classify it,which can be used as the first choice for patients with single coronary artery.
