Accidental esophageal intubation via a large type C congenital tracheoesophageal fistula: A case report

Figure 2 Tracheal computed tomography of the neonate. A: Sagittal image. The measured size of the fistula is 6.60 mm (red bidirectional arrow). The trachea and esophagus are at an obtuse angle of approximately 146° (orange lines). The measured length from the lip to the carina to predict the appropriate depth of the endotracheal tube is approximately 9.8 cm (yellow dashed line); B: Coronal image. The measured size of the fistula is 4.54 mm (red bidirectional arrow). The fistula is 10.2 mm above the carina (orange bidirectional arrow). T: Trachea; E: Esophagus; O: Opening of the fistula; C: Carina.
