Diastematomyelia is a congenital condition where the spinal cord is split by a bony or cartilaginous septum. Neurological signs and symptoms arise when this septum tethers the spinal cord. Surgical detethering often improves symptoms; however, recurrent tethering of the cord is increasingly recognised as a long-term complication. In order to prevent retethering many techniques have been used, including early patient mobilisation and sectioning of the cord. Dorsal expansile duroplasty, using synthetic grafts, is a commonly used technique to prevent recurrent dorsal tethering. We present a 31-year-old woman with recurrent ventral tethering of the cord where we used expanded polytetrafluoroethylene (Gore Preclude MVP Dura Substitute; WL Gore and Associates, Flagstaff, AZ, USA) to cover the ventral dural surface, separating the cord from its dural site of tethering. This technique may be useful to prevent ventral retethering in diastematomyelia.
脊髓纵裂是一种先天性疾病，其特征是脊髓被骨性或软骨性隔分开。当隔带束缚脊髓时，会出现神经体征和症状。手术松解通常可以改善症状；然而，越来越多的人认识到脊髓再束缚是一种长期并发症。为了防止再束缚，已经使用了许多技术，包括早期患者动员和脊髓切断术。使用合成移植物的背侧扩张性硬脑膜成形术是一种常用的技术，用于防止背部再束缚。我们介绍了一位 31 岁的女性，她患有脊髓腹侧再束缚，我们使用膨体聚四氟乙烯（戈尔普雷塞杜拉 MVP 硬脑膜替代物；戈尔和协会，亚利桑那州弗拉格斯塔夫，美国）覆盖腹侧硬脑膜表面，将脊髓与其硬脑膜束缚部位分开。这种技术可能有助于预防脊髓纵裂中的腹侧再束缚。
