title: [Two cases of thoracic aneurysm with aberrant origin of the aortic branches: diagnosis and strategy].
abstract: 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.
