摘要
目的 分析了多种因素对肺穿刺活检气胸发生率的影响。方法 46例病人均在X线透视引导下操作。所分析的各种因素为病灶大小、位置、穿刺次数、肺气肿及穿刺后体位。结果 46例病人中 9例发生气胸 (19.6 % ) ,9例肺气肿病人中 4例发生气胸 (44 .4% ) ,其中 2例经胸腔置管引流治愈。10例病灶 <3cm者 3例产生气胸 (30 % )。穿刺点向下卧位的 2 0例中 4例产生气胸 (2 0 % ) ;剩余的 2 6例自由卧位中 5例产生气胸 (19.2 % )。结论 经皮肺穿活检中的病灶愈小气胸发生率愈高。肺气肿病人肺穿后气胸发生率较高 ,且常为症状性气胸。穿刺点向下及非向下卧位对气胸的发生率没有明显影响。
Objective To analyze the influence of multiple variable factors on the occurance rate of pneumothorax associated with transthoracic needle aspiration biopsy of the lung. Methods Fluoroscopically guided lung biopsies were performed in 46 patients. Variable factors were analyzed including lesion size, location, number of puncture, presence of emphysema and patients position after needle biopsy of the lung. Results Pneumothorax occurred at 9 (19.6%) of 46 patients and that occurred at 4 (44.4%) of 9 emphysematous patients. Among them 2 necessitated chest drainage tube placement. The pneumothorax occurance rate was 30% (3/10) for lesions of diameter 3cm or less in size. In the dependent group, pneumothorax occurred in 4 of 20 patients (20%). In the nondependent group, pneumothorax occurred in 5 of 26 patients (19.2%). Conclusion The correlation showed that increasing frequency of pneumothorax with decreasing size of lesions. An increased rate of pneumothorax was correlated with presence of emphysema. Patients with emphysema are more likely to have a symptomatic pneumothorax. No significant differences were found in the incidence of pneumothorax between patients placed with the puncture site dependent after biopsy and those placed with the puncture site nondependent.
