目的探讨改变穿刺点抽吸对治疗CT引导下肺穿刺活检并发气胸的价值。方法回顾性分析2012年1月至2014年1月CT引导下经皮肺穿刺活检术后并发气胸并行抽气治疗患者的相关资料,比较常规抽吸与改变穿刺点抽吸对气胸的疗效差异。结果 85例进行常规抽吸治疗气胸患者,有效率68.2%(58/85),其中15例完全缓解,43例部分缓解;常规抽吸无效占31.8%(27/85),之后再改变穿刺点后穿刺抽吸,其中完全缓解3例,部分缓解21例,无效而采用胸腔闭式引流术者3例;增加使用改进方法后气胸治疗总有效率由68.2%(58/85)上升至96.5%(82/85)。结论采用改变穿刺点抽吸气体可使CT引导下肺穿刺活检术并发气胸治疗成功率明显增加。
Objective To explore the value of changing the puncture point suction for the treatment of pneumothorax by CT guided lung biopsy. Methods The clinical data of patients undergoing pneumoconiosis complicated with pneumothorax after CT guided percutaneous pneumocentesis biopsy were retrospectively analyzed. The curative effect of pneumothorax was compared between conventional suction and modified puncture point suction. Results 85 patients were treated with conventional suction pneumothorax, the effective rate was 68.2% (58/85), of which 15 patients were completely relieved, 43 patients partially relieved; conventional aspiration invalid accounted for 31.8% (27/85), and then changed the puncture point After puncture and aspiration, three cases were completely relieved, 21 cases partially relieved, while 3 cases were treated with closed thoracic drainage. The total effective rate of pneumothorax increased from 68.2% (58/85) to 96.5% after using the improved method. (82/85). Conclusions The changing rate of aspiration gas can improve the success rate of CT-guided lung biopsy and pneumothorax.
