目的探讨CT引导下肺穿刺抽吸、冲洗治疗外周肺脓肿的疗效和临床价值。方法在CT定位引导下用套管式穿刺针对15例外周肺脓肿进行抽脓、冲洗,根据抽取脓液的细菌培养和药物敏感试验结果选用有效抗生素全身治疗。结果患者自觉症状迅速好转,体温在1-2d内降至正常,2周后CT复查,15例患者脓腔内均无脓液重新出现,炎症病变区缩小,20-35d13例患者相继治愈出院,2例患者明显好转。结论该项技术用于治疗肺脓肿具有疗效好、安全方便、定位准确、损伤少、并发症少等特点,可缩短疗程,提高治愈率。 Objective To investigate the efficacy and clinical value of CT-guided pulmonary aspiration and irrigation in the treatment of peripheral pulmonary abscess. Methods Thoracotomy was performed on 15 cases of peripheral lung abscess under the guidance of CT positioning. The patients were treated with potent antibiotics based on bacterial culture and drug sensitivity test. Results The symptoms of patients improved rapidly, body temperature dropped to normal in 1-2d, 2 weeks after CT review, no abscess in 15 patients reappeared, reduced inflammatory lesions, 20-35d13 patients were cured after discharge, 2 patients were significantly improved. Conclusion The technique is effective in treating lung abscess and has the advantages of good curative effect, safe and convenient operation, accurate positioning, less damage and less complications.
