Clinical Analysis of Iatrogenic Pneumothorax / 대한흉부외과학회지

ABSTRACT

BACKGROUND: This study was designed to determine etiologic factors for iatrogenic pneumothorax in an era of increased use of invasive procedures and to evaluate its impact on morbidity. MATERIAL AND METHOD: Subjects were 112 patients (65 men and 47 women ranging in age from 20 to 90 years) who were diagnosed with an iatrogenic pneumothorax between January 2005 and December 2008. We reviewed medical records retrospectively. RESULT: The leading causes of iatrogenic pneumothorax were percutaneous needle aspiration (50), central venous catheterization (29), acupuncture (14), thoracentesis (8) and positive pressure ventilation (7). The majority of the patients (60 of 114) were treated with chest tubes. The mean duration of hospital treatment was 5.8 (+/-4.0) days. Hospitalization was prolonged in 24 patients (21.1%). No patient died from iatrogenic pneumothorax. CONCLUSION: In our study, the most common cause of iatrogenic pneumothorax was percutaneous needle aspiration. The mortality and morbidity from iatrogenic pneumothorax is not significant. The recognition of pneumothorax, depends on careful examination after completion of an invasive procedure, and should be followed by prompt and definitive therapy.
