目的探讨多节段椎管内肿瘤的手术方法及脊柱稳定性的维护。方法我院近3年的手术病例6例,对6例多节段椎管内肿瘤病人的临床特点、影像学表现、手术方式和疗效进行回顾性分析,病变位于胸段1例,胸腰段3例,腰段2例;6例病人肿瘤均位于髓外硬脊膜下。肿瘤性质为神经鞘瘤4例,脊膜瘤1例,神经纤维瘤1例。均行手术切除。结果 6例病人均全切肿瘤,恢复良好,随访2年,见患者脊柱无明显变形。结论椎管内多节段肿瘤通过后椎板成形,可以完全暴露肿瘤,术后还纳椎板固定有助于患者脊柱的稳定。 Objective To investigate the surgical method of multi-segment spinal canal tumor and the maintenance of spinal stability. Methods Six cases of surgery in our hospital in the past three years were retrospectively analyzed in 6 cases of multi-segment intraspinal tumor patients. The clinical manifestations, surgical modalities and therapeutic effects were retrospectively analyzed. The lesions were located in thoracic region, thoracolumbar region 3 cases, lumbar in 2 cases; 6 cases of patients with extramedullary tumors are located in the subdural. The tumor nature of schwannoma in 4 cases, 1 case of meningioma, neurofibroma in 1 case. All patients underwent surgical resection. Results All 6 patients underwent complete resection of the tumor with good recovery. The patients were followed up for 2 years without any obvious deformation of the spine. Conclusions Multi-segment spinal canal tumor posterior laminectomy can completely expose the tumor. After operation, it is also helpful to stabilize the spine.
