Down syndrome and aberrant right subclavian artery

Area of Science:

• Vascular Surgery
• Pediatric Gastroenterology
• Clinical Genetics

Background:

• Feeding problems are common in children with Down syndrome (DS), often linked to congenital defects or hypotonia.
• Aberrant right subclavian artery (ARSA), a rare vascular anomaly, is increasingly recognized as a potential cause of esophageal issues.
• Evaluating the association between ARSA and feeding difficulties in DS is crucial for accurate diagnosis and management.

Observation:

• This study highlights the increased prevalence of ARSA in patients with Down syndrome.
• ARSA can present as an unusual cause of dysphagia, particularly with solid foods.
• Feeding difficulties in DS patients warrant consideration of ARSA, especially when other causes are ruled out.

Findings:

• Aberrant right subclavian artery (ARSA) occurs more frequently in individuals with Down syndrome (DS).
• ARSA can manifest as a cause of dysphagia, impacting the passage of solid food.
• Diagnostic tools like echocardiography, barium esophagram, and CT angiography can identify ARSA.

Implications:

• Increased awareness of ARSA in DS can improve the evaluation of feeding difficulties.
• Targeted investigation for ARSA may be beneficial for selected DS patients with unexplained feeding issues.
• Corrective surgery for ARSA should be reserved for specific cases where it is the definitive cause of symptoms.
