Why did the pneumothorax get worse?
In this case, the cause cannot be seen on the x-ray. Examination of the chest tube setup demonstrated that the Heimlich valve had been connected the wrong way around.
- CXR: Iatrogenic pneumothorax secondary to insertion of a port.
- CXR: Placement of chest tube with resolution of the pneumothorax.
- CXR: 24 hours follow up: iatrogenic tension pneumothorax with complete left lung collapse, from erroneous attachment of the Heimlich valve to the chest tube.
- CXR: Resolution of tension pneumothorax after reversing the one-way valve back to its correct orientation.
