【摘要】：目的分析总结先天性单一冠状动脉(SCA)的CT表现,提高对该畸形影像学表现的认识。方法回顾性分析25例经CT冠状动脉造影(CTA)诊断为SCA患者资料,使用第二代双源CT多种后处理方法观察冠状动脉变异情况,并与冠状动脉造影(CAG)结果进行对照分析。结果 25例SCA患者中,左冠状动脉缺如单右冠状动脉畸形2例,右冠状动脉缺如单左冠状动脉畸形23例,且所有病例均通过多平面重组(MPR)、最大强度投影(MIP)和容积再现(VR)等显示异常血管的形态。其中8例患者在CTA检查后行CAG检查,结果证实为SCA,CTA对其检出率为100%。结论双源CT血管成像可以准确显示正常和畸形的冠状动脉,清晰表现单一冠状动脉走行分布,可以作为诊断SCA的首选检查方法。SCA特征性CTA表现,可为临床早期干预和手术治疗提供可靠的影像学证据。
[Abstract]:Objective to analyze the CT findings of congenital single coronary artery disease (SCA) and to improve the understanding of the imaging findings. Methods the data of 25 patients with SCA diagnosed by CT coronary angiography were retrospectively analyzed. The variation of coronary artery was observed by multiple post-processing methods of second generation CT, and the results were compared with the results of coronary angiography (CAG). Results in 25 patients with SCA, there were 2 cases of left coronary artery deformity and 23 cases of right coronary artery deformity. In all cases, the abnormal blood vessels were displayed by multiplanar recombination MPRP, maximum intensity projection (MIP) and volumetric reappearance (VRV). CAG was performed in 8 patients after CTA. The results showed that the positive rate of CAG was 100%. Conclusion Dual-source CT angiography can accurately display the normal and abnormal coronary arteries, and clearly show the distribution of the single coronary artery. It can be used as the preferred diagnostic method for SCA. It can provide reliable imaging evidence for early clinical intervention and surgical treatment.
