The authors describe the unusual case of a 50-year-old woman who suffered from sciatic pain due to periligamentous trapped epidural gas after lumbar sequestrectomy. The patient underwent removal of free herniated disc material via a translaminar approach through the L-5 lamina without discectomy. Four days later she suffered from recurrent pain, and neuroimaging studies revealed an epidural gas formation at the site of the sequestrectomy. After evacuation of the gas, her pain resolved. Postoperative intraspinal gas may be symptomatic in the rare case.
作者描述了一例不同寻常的病例，一名50岁女性在腰椎间盘摘除术后因韧带周围被困硬膜外气体而遭受坐骨神经痛。该患者通过L5椎板的经椎板入路在未进行椎间盘切除术的情况下清除了游离的突出椎间盘物质。四天后，她再次出现疼痛，神经影像学检查显示在椎间盘摘除部位有硬膜外气体形成。气体排出后，她的疼痛缓解。术后椎管内气体在罕见情况下可能会引起症状。
