238 – Tracheal Fissure

Tracheoesophageal fistula: Intense edema of the entire tracheal mucosa, with extensive areas of submucosal hemorrhage.

The edema becomes irregular in the posterior wall and a U-shaped fissure occupies the center of the image.

The dark coloration of its path is due to the methylene blue instilled in the esophagus for its detection.
