45例椎管内原发性肿瘤的外科治疗体会

目的：探讨椎管内肿瘤的临床诊断和手术治疗效果。方法：总结45例椎管内原发肿瘤患者的临床表现，影像学检查，手术方式及术后脊髓功能改善情况。结果：椎管内原发性肿瘤患者的临床表现为腰背痛、四肢感觉异常、运动和功能障碍。MPd检查为椎管内占位、脊髓受压征象。45例均已行手术治疗，35例肿瘤切除完整，1O例大部分切除。术后均经病理证实为椎管内良性肿瘤，其中神经鞘瘤25例、神经纤维肿瘤10例、纤维脂肪肿瘤3例、脊膜瘤7例。有4例术前出现不完全截瘫，术后3例完全恢复，有1例遗留部分功能障碍，其它患者术后临床症状均有明显改善。结论：影像学检查对椎管内原发肿瘤有较高的检出率，MRI检查对明确病变性质和部位有重要意义，最终确诊依赖于病理诊断。椎管内原发肿瘤如能早期发现诊断和手术治疗，临床效果好。
