Oesophageal atresia may occur as a part of VACTER group of anomalies. What does ‘TB’ stand for ?
**Core Concept**
Oesophageal atresia is a congenital anomaly where the oesophagus does not develop properly, often presenting as a tracheoesophageal fistula. VACTERL association is a non-random combination of congenital anomalies that includes Vertebral anomalies, Anal atresia, Cardiac anomalies, Tracheo-Esophageal fistula, Renal anomalies, and Limb abnormalities.
**Why the Correct Answer is Right**
The VACTERL association includes a range of congenital anomalies that often occur together. Tracheo-Esophageal fistula (TEF) is a common component of this association, where there is an abnormal connection between the trachea and the oesophagus. This can manifest as an oesophageal atresia with or without a TEF. The T in VACTERL stands for Tracheo-Esophageal fistula, which is a key component of this association.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately represent the VACTERL association.
**Option B:** This option is incorrect because it introduces a new term not related to the VACTERL association.
**Option C:** This option is incorrect because it is a distractor and not a valid component of the VACTERL association.
**Clinical Pearl / High-Yield Fact**
Remember the VACTERL association as a mnemonic to recall the key components of this congenital anomaly group: Vertebral, Anal, Cardiac, Tracheo-Esophageal, Renal, and Limb.
**Correct Answer: C. Tracheo-Esophageal.**
