经半椎板入路切除椎管内肿瘤

Resection of intraspinal tumors by unilateral hemilaminectomy

目的探讨经半椎板入路切除椎管内肿瘤的疗效。方法回顾性分析2004年10月至2008年6月23例采用经半椎板入路显微切除椎管内肿瘤的临床资料。结果本组23例肿瘤均完全切除。无1例出现新的神经功能损伤及严重并发症,所有患者在术后早期即可下床活动。所有患者均进行10～58个月的随访,未发现肿瘤复发及脊柱的不稳定。结论半椎板入路显微手术治疗椎管内肿瘤损伤小,避免术中过度显露,有利于保持脊柱的稳定性,患者术后恢复较快。

Objective To observe the effect of microsurgical removal of intraspinal tumors by unilateral hemilaminectomy.Methods A total of 23 patients with intraspinal tumors underwent microsurgery by unilateral hemilaminectomy were analyzed retrospectively from October 2004 to June 2008.Results All the tumors were totally removed.No neurological dysfunction or complications were found after operation.Early ambulation after operation was achieved in all the patients.During 10~58 months＇ follow-up,no recurrence and spinal instability were found.Conclusion The microsurgical removal of intraspinal tumors by unilateral hemilaminectomy is minimally invasive,which avoids the overexposure of surgical field,keeps the stability of spine,and shortens the hospitalization.
