病灶因素对CT导向下经皮肺穿刺活检并发症发生率的影响

目的:探讨CT导向下经皮肺穿刺活检并发症发生率与病灶大小、深度和部位之间的关系。方法:复习CT导向下肺部病变穿刺活检184例,所有病灶按大小分为≥3cm(122个)和<3cm(62个)两组,按病灶深度分为≥2cm(98个)和<2cm(86个)两组,按病灶部位分为上肺野(28个)、中肺野(61个)和下肺野(95个)3组,分别统计各组的并发症发生率。结果:直径<3cm病灶的并发症发生率(气胸19.23%,出血44.19%)明显高于≥3cm病灶(气胸5.17%,出血15.09%,P<0.05);深度≥2cm病灶的并发症发生率(气胸13.27%,出血25.51%)显著高于<2cm者(气胸3.49%,出血11.63%,P<0.05);不同肺野病灶的并发症发生率之间差异无显著性意义(P>0.05)。结论:病灶大小和深度是影响CT导向下经皮肺穿刺活检并发症发生率的主要因素。

The Influence of Lung Lesion′s Factors to the Complication Rate in the Process of CT Guided Percutaneous Transthoracic Lung Biopsy

Objective:The compare the complication rates of CT-guided percutaneous transthoracic lung biopsy for pulmonary lesions with different size,depth and location,and to explore the possible factors about lesions to the complication rate.Methods:CT-guided percutaneous transthoracic lung biopsy was performed in 184 cases.All lesions were divided into some groups according to the size,depth and lesion.Of the 184 lesions,122 were larger than or equal to 3cm in diameter and 62 were smaller than 3cm.98 were more than or equal to 2cm in depth and 86 were lesser than 2cm and 28 lesions located in upper lung field,61 in middle field,and 95 in lower field.The complication rates between the groups were statistically analyzed.Results:For lesions smaller than 3cm,the pneumothorax rate was 19.23% and bleeding rate was 44.19%;significantly higher than those larger than or equal to 3cm,in which the pneumothorax rate and bleeding rate were 5.17% and 15.09% respectively.The occurrence of pneumothorax and bleeding for lesions 2cm or more than 2cm deep were 13.27% and (25.51%) respectively,significantly higher than those lesser than 2cm in depth (3.49% and 11.63%).There was no significant difference among the complication rates for lesions with different lung field location.Conclusion:Lesion size and lesion depth are significant factors related to the occurrence of complications in the process of CT-guided percutaneous transthoracic lung biopsy.
