Adolescent Idiopathic Scoliosis tends to be complicated with spine and ribcage deformities. In addition to the coronal curvature, among the features of right thoracic scoliosis, flat chest, ribcage rotation, cardiac compression and an aortic left shift are also observed. Aorta is known to shift in a leftward direction, especially at the mid-thoracic level. The cause of aortic left shift in scoliosis is not known. To clarify the features of a scoliosis deformity, especially the relationship of the aortic left shift and the flat chest in scoliosis, we investigated the CT scan images of scoliosis patients. ⋯ In right thoracic scoliosis, an aortic left shift correlated with both flat chest and the ribcage rotation.
