A female patient was recently admitted to the hospital bed. She was only 40 years old. She started coughing a year ago, accompanied by chest tightness and discomfort. At that time, no special problems were found in the chest CT scan, but the patient The symptoms persisted and did not relieve, the antibiotic treatment was not effective, and the symptoms recurred repeatedly. The symptoms became more severe at night, and the symptoms gradually worsened. The lung function examination showed extremely severe obstructive ventilation dysfunction. The symptoms still could not be relieved after the asthma treatment. Intractable diseases.
In other hospitals, bronchoscopy was also checked, and no definite bacteria were found, but bronchoscopy was not performed at that time, so there was no final diagnosis, such as this inexplicable lung function jumping off the building and causing asthma The nature of the problem cannot be determined without a bronchoscopy biopsy. Preliminary analysis of chest CT findings does not rule out the possibility of bronchiolitis obliterans.
The root cause of bronchiolitis obliterans is the thickening of the tracheal wall, resulting in tracheal stenosis and increased resistance to inhaled gas. People breathe an average of 20,000 times a day. If the resistance increases and breathing is laborious, people will feel particularly tight in the chest.
