tracheoesophageal fistula

tracheoesophageal fistula An abnormal communication between the trachea and esophagus. Abbreviated TEF. A TEF can be present at birth (congenital) or acquired. Congenital TEF is often associated with other birth defects. Most patients with congenital TEFs are diagnosed immediately following birth or during infancy. Congenital TEFs are often associated with life-threatening complications and require surgical repair. Acquired TEFs can occur secondary to cancer, trauma, infection, and ruptured diverticula.
