摘要
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。
Objective To discuss the selection of access in CT guided percutaneous biopsy of atlantoaxial lesions, and to evaluate the safety and clinical applications of this procedure.Materials and Methods CT guided percutaneous biopsy was performed in 25 patients with atlantoaxial lesions, which involved all parts of the atlas and axis. Precise needle access was designed according to the location of each lesion.Results Of 25 cases, the diagnosis was confirmed pathologically in 24, the bioptic accuracy was 96%. Operation was done in 12 cases. The coincidence rate of biopsy with surgical pathology was 100%. No complications occurred.Conclusion The atlantoaxial lesions have complex relations with adjacent anatomical structures, such as spinal cord and large vessels, thus, a proper access for needle puncturing is the key point for this technique. The procedure is quite safe when the large vessels and spinal cord can be kept away from the needle.
