Final answer:
The three kinds of TracheoEsophageal Fistulas and Septum malformations are Type A, Type B, and Type C, referring to different configurations of abnormal connections between the trachea and the esophagus.
Step-by-step explanation:
The three kinds of TracheoEsophageal Fistulas (TEF) and TracheoEsophageal Septum malformations mentioned are Type A, Type B, and Type C. These types refer to various anatomical configurations where there may be a connection (fistula) between the trachea and the esophagus, which can cause severe complications because the esophagus and the trachea are not usually connected.
Type A TEF corresponds to a situation where there is an esophageal atresia with no fistula, meaning the esophagus does not form properly and ends in a blind pouch. Type B involves an esophageal atresia with a proximal TEF, and Type C which is the most common, includes esophageal atresia with a distal TEF. These anomalies are a result of the abnormal development of the tracheoesophageal septum during the embryonic stage, which normally separates the trachea and esophagus into distinct tubes.
