Abstract：
An interspinous spacer is a minimally invasive implantable device for the treatment of lumbar spinal stenosis. The in situ implant may prevent safe and successful spinal anesthesia because its position can obstruct the path of the spinal needle. Lumbar neuraxial ultrasonography has been shown to aid in performance of neuraxial anesthesia in patients with challenging anatomy. Currently, there are no reported cases of ultrasound-assisted spinal anesthesia in patients with interspinous spacers. We present a case in which ultrasonography assisted the successful administration of a spinal anesthetic by avoiding an indwelling lumbar interspinous spacer.
摘要：
棘突间间隔器是用于治疗腰椎管狭窄症的微创可植入装置。原位植入物可防止安全和成功的脊髓麻醉,因为其位置可阻碍脊髓针的路径。腰椎神经轴超声检查已被证明可以帮助具有挑战性解剖结构的患者进行神经轴麻醉。目前,在有棘突间间隔区的患者中,没有报道超声辅助椎管内麻醉的病例.我们介绍了一个案例，其中超声检查通过避免留置腰椎棘突间间隔器来帮助成功使用脊髓麻醉剂。
