Anomalies and features associated with Down syndrome include:

• A. Atlanto-occipital instability
• B. Thyroid hypofunction
• C. Endocardial cushion defect
• D. All of the above are correct

Answer: (D)

Down syndrome is associated with a range of problems that affect anesthesia planning, including cervical spine stability, thyroid function, and heart structure. Atlanto-occipital instability comes from ligamentous laxity at the craniovertebral junction, which means careful handling of the neck during airway management to avoid spinal cord injury or catastrophic neck movement. Thyroid hypofunction is common in these patients and can alter drug metabolism and recovery, so preop screening and appropriate management of hypothyroidism help optimize anesthesia. Endocardial cushion defects are a classic congenital heart lesion in Down syndrome, reflecting common AV septal defects that influence hemodynamics and perioperative risk, making preoperative cardiac assessment essential. Because all three of these issues can be present, “all of the above” is the best answer.
