文献摘要 全文翻译

Vacuum disc phenomenon is seen frequently with degenerative disc disease and is characterized by the collection of gas in the disc space. Although the accumulation of gas within the disc space does not have clinical significance, symptoms may develop when occurring within the spinal canal. We present a 60-year-old female patient with low back and left leg pain occurring for 3 months before admission to our clinic. Straight leg raise test was 50 degrees in the left leg. Magnetic resonance imaging showed a narrowing of the L5-S1 disc space with vacuum disc phenomenon and hypointense cystic mass in T1 and T2-weighted images. The decision for surgery was made and left L5-S1 hemilaminectomy and foraminotomy was performed. The cyst wall was adherent to the root and dura mater and was partially excised. The patient was pain-free on the first postoperative day. In cases of gas accumulation in the spinal canal, discogenic pain may occur. Surgical therapy is still an acceptable method for the treatment of vacuum disc phenomenon and accumulation of gas within the spinal canal.

椎间盘真空现象是常见的退行性椎间盘疾病,其特征是气体在盘空间的积聚。虽然在椎间盘空间内的气体积累不具有临床意义,但该现象在椎管内出现时可能会导致病变。文中讲述了一例60岁的女性患者,门诊就医时已持续了3个月的腰背和左腿疼痛。左腿直腿抬高试验为50度。磁共振成像显示,T1加权像出现椎间盘真空现象、低信号囊性肿块,T2加权像在L5-S1椎间隙变窄。行L5-S1左侧椎板切除术和椎间孔切开术。附着于神经根和硬脑膜的囊肿壁被部分切除。患者在术后第一天无疼痛。但在椎管内气体积累的情况下,可能会出现椎间盘源性疼痛。结果表明,外科疗法是治疗椎管内真空盘现象和气体积累的一种可选方法。
