We present two cases of thoracic aortic aneurysms with anomalous origin of the aortic arch branches. One was a 72-year-old female with a ruptured descending thoracic aneurysm and aberrant origin of the right subclavian artery. The other was a 64-year-old male with a saccular distal arch aneurysm and aberrant origin of the left vertebral artery. Preoperative examinations included angiography, computed tomography (CT), three dimensional enhanced CT (3DCT), digital subtraction angiography (DSA), and magnetic resonance imaging (MRI). Understanding the structure of neck vessels is important in deciding where to clamp or to reconstruct in surgical repair of the aortic arch. 3DCT was the most useful examination for this understanding.
我们报告两例伴有主动脉弓分支异常起源的胸主动脉瘤病例。一例为72岁女性，患有降胸段动脉瘤破裂且右锁骨下动脉起源异常。另一例为64岁男性，患有囊状主动脉弓远端动脉瘤且左椎动脉起源异常。术前检查包括血管造影、计算机断层扫描（CT）、三维增强CT（3DCT）、数字减影血管造影（DSA）和磁共振成像（MRI）。在主动脉弓手术修复中，了解颈部血管结构对于决定夹闭或重建的位置很重要。3DCT是进行这种了解最有用的检查。
