目的总结半椎板入路显微手术切除椎管内肿瘤的经验。方法对5年来经半椎板入路显微手术切除椎管内肿瘤,肿瘤切除后行游离椎板复位固定的48例患者的临床资料进行分析总结。结果本组椎管内肿瘤48例,肿瘤在显微镜下全切除47例,1例因肿瘤与神经根粘连紧密,在神经根处残留少许肿瘤包膜。所有患者术前神经系统症状得到改善。术后随访均行X线检查,显示回植椎板与椎体骨性融合良好。结论应用半椎板入路和椎板复位固定显微手术切除椎管内肿瘤,即可以满意的切除肿瘤,又有利于维护术后脊柱稳定系性。
Objective To summarize the experience of microsurgical resection of intraspinal tumors by means of semi-laminar approach. Methods The clinical data of 48 patients who underwent microsurgical resection of spinal canal tumors by semi-laminar approach in 5 years after resection of the vertebral plate were retrospectively analyzed. Results 48 cases of this group of spinal canal tumor, the tumor under microscope in 47 cases of total excision, 1 case of tumor and nerve root adhesions close, leaving a little nerve root capsule tumor. Preoperative neurological symptoms were improved in all patients. All the patients were followed up for X-ray examination, which showed that the transplanted lamina and vertebral body had a good bone fusion. Conclusion The application of semi-lamina approach and lamina fixation and microsurgical removal of spinal canal tumors, that can be satisfactorily resected the tumor, but also conducive to maintaining the stability of the postoperative system.
