From Wikipedia, the free encyclopedia. A bronchopleural fistula (BPF) is a fistula between the pleural space and the lung. It can develop following pneumonectomy, post traumatically, or with certain types of infection. It may also develop when large airways are in communication with the pleural space following a large pneumothorax or other loss of pleural negative pressure, especially during positive pressure mechanical ventilation. On imaging, the diagnosis is suspected indirectly on radiograph.
Tracheoesophageal fistula is also known as TE fistula or simply TEF. TE fistula is a birth defect, which is an abnormality that occurs as a fetus is forming in its mother's uterus. When a baby with a TE fistula swallows, the liquid can pass through the abnormal connection between the esophagus and the trachea.
