摘要
目的探讨CT引导下经皮肺穿刺活检术中影响针胸膜夹角的因素。方法 828例肺内孤立性病变患者接受CT引导下经皮穿刺肺活检,分别记录病变大小、病变部位、穿刺点位置及进针深度等。将以上变量与针胸膜夹角进行统计学分析。结果位于双肺上叶的病变与小的针胸膜夹角有关;不同病变大小、不同进针深度的针胸膜夹角病例数分布不一致;不同穿刺点位置的针胸膜夹角病例数分布一致。病变在20～29mm时,针胸膜夹角与穿刺例数无相关关系。结论病变部位可能影响针胸膜夹角,尤其是双肺上叶的病变与针胸膜夹角大小有密切关系。
Objective To analyze the impact factors of needle-pleural angle during CT guided percutenous needle puncture biopsy of the lung.Methods Totally 828 patients who diagnosed as solitary lung lesions received CT guided percutenous needle puncture lung biospy.The size,location,puncture site and needle path length of lesions were recorded and analyzed statistically with the needle-pleural angle.Results The lesions located in bilaterel superior lobe were associated with small needle-pleural angle.Different lesion sizes and the depth of the needle into the needle-pleural angle distribution were inconsistent with the number of cases,but the different positions of the puncture of the needle-pleural angle distribution was consistent with the number of cases.The lesions sized 20—29 mm had no correlation with the number of cases.Conclusion The lesions＇ location may affect the needle-pleural angle,the lesions especially located in bilaterel upper lobes are significantly associated with the needle-pleural angle.
