目的 全面系统地探讨寰枢椎病变CT引导下穿刺活检的入路选择 ,评价其安全性及临床应用价值。材料与方法 2 5例寰枢椎病变行CT引导下经皮穿刺活检。穿刺部位包括C1及C2 椎体的各个部位。根据病变的部位不同 ,设计相应的进针路径 ,穿刺取材。结果 2 5例中 ,2 4例获得明确病理诊断 ,穿刺活检准确率 96 %。其中 12例手术治疗 ,穿刺病理与手术病理符合率 10 0 %。无并发症发生。结论 寰枢椎病变解剖关系复杂 ,毗邻脊髓及重要的大血管 ,选择适宜的穿刺路径尤为关键。寰枢椎病变不同的穿刺路径 ,只要避开大血管及脊髓 ,操作是比较安全的。为临床确定治疗方案提供了必要的病理依据
Objective To comprehensively and systematically investigate the approach selection of CT-guided biopsy of atlantoaxial lesions and evaluate its safety and clinical application value. Materials and Methods 25 cases of atlantoaxial lesions underwent CT-guided percutaneous biopsy. The puncture site included various parts of the C1 and C2 vertebral bodies. According to the different parts of the lesion, design the corresponding needle path, puncture the material. Results Out of 25 cases, 24 cases were confirmed pathological diagnosis. The accuracy rate of biopsy was 96%. Among them, 12 cases were treated by surgery. The coincidence rate between puncture pathology and surgical pathology was 10%. No complications occurred. Conclusion The anatomic relationship between atlantoaxial lesions is complex, adjacent to the spinal cord and important large blood vessels. Selecting a suitable puncture path is particularly critical. Different puncture paths for atlantoaxial lesions are safer as long as they avoid large blood vessels and the spinal cord. Provides the necessary pathological basis for the clinical determination of treatment options
