Autonomic nerve system (ANS) regulates intercostal vascular nutrition (internal mammary artery), and its pathological status leads to developmental asymmetry of the trunk and rib cage, and consequently producing scoliotic deformity of the spine. The aim of this study is to investigate the possible causation of idiopathic scoliosis in development abnormalities of ANS. We evaluated samples taken from 12 patients with idiopathic scoliotic deformities and a control set of three patients without scoliotic deformity. We examined the samples of autonomic nerves taken from convexity and concavity of the scoliotic deformity during the patients' surgical correction by the transthoracic approach. We used the electronmicroscopic method to analyse samples, and the morphometric method for statistical evaluation.Introduction
