[Spontaneous Pneumothorax During Pregnancy Successfully Managed with a Thoracic Vent before Surgical Therapy; Report of a Case].

A 34-year-old pregnant woman presented to our department at 31 weeks of gestation after being diagnosed as spontaneous pneumothorax based on chest X-ray findings. We inserted a Thoracic Vent( TV), and she was followed as an outpatient. However, since pneumothorax recurred twice after the TV was removed, she was finally admitted to the Department of Obstetrics because threatened premature delivery was suspected. The collapsed lung did not re-expand, and the surgery for pneumothorax was done before childbirth. After thoracic surgery, she safely gave birth to a girl at 40 weeks of gestation. Outpatient therapy for spontaneous pneumothorax with TV is concerned to be a useful treatment even for pregnant women.
