CT引导下经皮穿刺肺脓肿引流术的临床应用

Clinical application of percutaneous needling lung abscess drairnage under CT guidance

目的 探讨CT引导下经皮穿刺肺脓肿引流术的临床应用。方法 对 18例肺脓肿行CT引导下经皮穿刺引流术 ,其中 8例直接用穿刺针抽吸脓液 1～ 3次 ,10例放置引流管持续引流。结果 17例手术获得成功 ,成功率 94 .4 % (17 18)。随访 11～ 35d ,症状明显好转、病灶缩小或消失 16例 ,治愈率 88.9% (16 18)。并发症 :穿刺发生气胸 4例 ,气胸量 <30 % 3例 ,>30 % 1例。结论 CT引导下经皮穿刺肺脓肿引流术 ,可缩短病程 ,创伤小 ,操作简单 ,只要掌握好适应证和技术要领 ,成功率、治愈率高 ,并发症少而轻 ,值得推广应用。

Objective To discuss the clinical application of drainage for lung abscess by needle puncture under CT guidance. Methods 18 cases of lung abscess were drainaged by needle puncture under CT guidance, including direct aspiration by puncture needle 1-3 times (n=8) and retaining drainage tube continuously (n=10). Results 17 cases with this procedure were succeeded possessing success rate of 94.7%(17/18). The patients were followed up for 11-35 days with symptom relieving better obviously and the focus shrinkage or disappeared (n=16), the curative rate reached 88.9%(16/18). The main complication was pneumothorax with capacities of <30%(n=3), >%(n=1).Conclusions The curative course of lung abscess can be shortened greatly by percutaneous needling drainage under CT guidance with mild trauma. The procedure is simple with high successful rate and less complication.
