Traumatic pneumothorax is produced due to a direct or indirect injury in the chest [5]; however, in some series, traumatic pneumothorax is classified depending on the cause, including iatrogenic pneumothorax and barotrauma in this classification, calling it simply penetrating and nonpenetrating pneumothorax [6].
A subcategory of traumatic pneumothorax is iatrogenic pneumothorax, which occurs as a consequence of diagnostic or therapeutic maneuvers (i.e., thoracoentesis, insertion of a central venous catheter, surgery, or mechanical ventilation).
The complications, including serious bleeding, iatrogenic pneumothorax, and respiratory failure, were reported.
Secondary spontaneous pneumothorax (SSP) occurs in older people with underlying pulmonary diseases, such as emphysema, asthma, acute or chronic infections, lung cancer, congenital diseases, catamenial pneumothorax, lymphangioleiomyomatosis (LAM).5-7 Traumatic pneumothorax is divided into three groups as blunt, penetrating, and iatrogenic pneumothorax.8
