A Case of H-type Tracheoesophageal Fistula Diagnosed by Esophagography in Prone Position

ABSTRACT

An H-type tracheoesophageal fistula is a rare congenital condition of which incidence is approximately 1 50, 000-80, 000 births. Although patient usually has recurrent respiratory symptoms such as choking episodes and cyanotic spells, its rarity and atypical symptoms may delay its detection. Besides, conventional esophagogram often fail to find the defect. We reported a case of H-type tracheoesophageal fistula, diagnosed by tube esophagram with infant in the prone position. During the test, contrast medium was injected while the catheter is slowly withdraws from lower esophagus.
