CT引导下肺内孤立性病变经皮穿刺活检并发症的分析

目的分析肺外围型孤立病变CT引导下经皮穿刺活检并发症的原因。方法选取2002-10～2004-10连续2年内的所有肺内外围型孤立病变行CT引导下肺穿刺活检的患者71例,回顾性研究总结穿刺活检的并发症发生率与年龄、性别、穿刺针所经肺组织深度、肿块周围有无肺气肿表现、穿刺的次数、穿刺针的粗细等几个方面的关系。结果并发症共26例次,气胸3例(4.23%),肺内出血9例(12.67%),出现血痰或血痰加重13例(18.3%),胸膜反应1例(1.41%)。经统计学分析,并发症的发生与穿刺针所经肺组织深度、病变周围肺气肿及穿刺次数和穿刺针的粗细有明显的相关性。结论CT引导下肺内病变经皮穿刺活检并发症以血痰最常见。病灶离胸膜的间距、病灶周围肺气肿、穿刺次数及穿刺针粗细是经皮穿刺肺活检并发症的危险因素。

CT-guided Percutaneous Transthoracic Needle Biopsy on Pulmonary Peripheral Solitary Lesions:A Retrospective Analysis of Complication

Objective To investigate the cause of complications in CT-guided percutaneous transthoracic needle biopsy(TNB) in peripheral solitary pulmonary lesions.Methods Seventy one patients (between October 2002 and October 2004) with peripheral solitary pulmonary lesions undergone TNB were included . The correlations among complications and age, sex, needle size, times of aspiration, lesion depth from the pleura were determined using SPSS statistic software.Results Of 71 cases , complications occurred in 26 cases ,including pneumothorax in 3(4.23%), hemorrhage in 9 (12.67%), hemoptysis in 13(18.30%),pleura response in 1(1.41%). There was significant correlation among the complications with needle size, times of aspiration and the lesion depth from the pleura,respectively.Conclusion Hemoptysis is the most common complication in CT-guided TNB in patients with peripheral solitary pulmonary lesions. The lesion depth, emphysema near the lesion, times of operation and needle size were the risk factors in CT-guided TNB.
