目的 分析经皮经肺CT引导下弹射肺活检并发症与各种危险因素的关系.方法 选择153例符合穿刺指征的病人给予经皮弹射肺活检,所选对象术前均给予肺功能、心电图检测,结果分为气胸组74例和非气胸组79例,评价病人的年龄、性别、穿刺针的直径、病灶的直径、深度、肺叶位置和病人肺功能与气胸的关系.结果 出现气胸16例,发生率10.5%.气胸组平均年龄高于无气胸组(P＜0.05),病灶直径小增加气胸发生率(P＜0.05),位置深的病灶增加气胸发生率(P＜0.05),穿刺针的外径粗的增加气胸发生率(P＜0.05),肺功能差的增加气胸发生率(P＜0.05).结论 年龄、病灶直径、病灶深度、肺功能、穿刺针的直径均与气胸发生有关.%Objective To analyze the relation between complication of CT-guided percutaneous lung biopsy and risky factors. Methods We evaluated the relation between pneumothorax and the risky factors including patients' age, gender,diameter of puncture needles,focal diameter and depth, pulmonary position and pulmonary function by means of PALB( percutaneous aspiration lung biopsy )of 153 patients. Results There were 16 cases of pneumothorax, and the rate was 10. 5% . The average age of pneumothorax group was older than that of non-pneumothorax group ( P <0. 05 ). Risky factors increasing the chances of pneumothorax( P < 0. 05 )included short focal diameter, deep focal position, wide outer diameter of puncture needles and poor pulmonary function. Conclusion Pneumothorax is related with such factors as age,focal diameter,focal depth,pulmonary function and diameter of puncture needles.
