目的：探讨经胸活检患者发生气胸风险的影响因素。材料和方法：在453例ct引导下的经胸活检中评估可能增加气胸风险的变量。评估两组因素：(1)与病灶相关（病灶周围是否存在肺气肿、病灶深度、空化、针眼轨迹是否存在裂隙/肺不张和胸膜标签）；(2)手术相关（活检类型、针头大小、穿刺次数、操作人员的经验水平）。所有变量均采用chi(2)检验和多元逻辑回归统计进行分析。结果：453例手术中有85例（18.8%）发生气胸。其中10例（11.7%）置入胸管。与气胸风险增加显著相关的变量是病变深度（P < 0.001）和肺气肿严重程度（P < 0.01）。结论：活检时穿过的肺实质长度是ct引导下经胸活检患者发生气胸的主要危险因素。气胸的风险也随着病灶周围肺气肿的严重程度而增加。(C) 2003爱思唯尔科学爱尔兰有限公司版权所有。
Objective: to evaluate the factors that could effect the risk of pneumothorax in patients undergoing transthoracic biopsy. Material and methods: variables that could increase the risk of pneumothorax were evaluated in 453 CT-guided transthoracic biopsies. Factors were evaluated in two groups: (1) lesion related (presence of emphysema around the lesion, lesion depth, cavitation, presence of fissure/atelectasis and pleural tag in the needle trajectory); and (2) procedure related (biopsy type, needle size, number of passages, level of experience of the operator). All variables were analysed by chi(2) test and multivariate logistic regression statistics. Results: pneumothorax was developed in 85 (18.8%) out of 453 procedures. A chest tube was inserted in ten (11.7%) of them. Variables that were significantly associated with an increased risk of pneumothorax were depth of the lesion (P < 0.001) and severity of the emphysema (P < 0.01). Conclusion: the length of the lung parenchyma traversed during the biopsy is the predominant risk factor for pneumothorax in patients undergoing CT-guided transthoracic biopsy. The risk of pneumothorax was also increased with the severity of the emphysema around the lesion. (C) 2003 Elsevier Science Ireland Ltd. All rights reserved.
