Superior mesenteric artery (SMA) syndrome is a rare complication that occurs after correction of scoliosis. A review of the literature suggests that the incidence of this syndrome may be decreasing, as methods for the correction of scoliosis have improved. We present the first report of SMA syndrome that occurred after segmental 'derotational' instrumentation. Computerized axial tomography was helpful in suggesting the diagnosis of this condition. The risk factors and pathophysiology of SMA syndrome are reviewed with respect to the biomechanical effects of casting and Harrington and segmental instrumentation systems on the spine. Attention to the three-dimensional nature of the scoliotic deformity, particularly in the sagittal plane, may help to predict those at risk for the development of this potentially fatal syndrome.
肠系膜上动脉（SMA）综合征是脊柱侧弯矫正术后发生的一种罕见并发症。文献回顾表明，随着脊柱侧弯矫正方法的改进，该综合征的发病率可能正在下降。我们报告了首例在节段性“去旋转”器械固定术后发生的SMA综合征。计算机断层扫描有助于提示该疾病的诊断。结合石膏固定以及哈林顿器械和节段性器械系统对脊柱的生物力学影响，对SMA综合征的危险因素和病理生理学进行了综述。关注脊柱侧弯畸形的三维特性，尤其是矢状面的特性，可能有助于预测发生这种潜在致命综合征的风险人群。
