A persistent right aortic arch caused esophageal constriction and megaesophagus in a filly. Respiratory issues appeared before swallowing difficulties, an unusual presentation for this condition.

Area of Science:

  • Veterinary Medicine
  • Comparative Pathology
  • Equine Science

Background:

  • Persistent right aortic arch (PRAA) is a congenital anomaly where the aorta fails to form correctly, potentially compressing the esophagus.
  • Esophageal abnormalities like megaesophagus and constriction can lead to significant gastrointestinal and respiratory complications in animals.

Observation:

  • A 14-month-old filly presented with chronic pharyngitis.
  • The filly exhibited clinical signs of respiratory dysfunction.
  • Regurgitation was a notable symptom, preceding the identification of dysphagia.

Findings:

  • The filly was diagnosed with incomplete esophageal constriction and megaesophagus.
  • The underlying cause was identified as a persistent right aortic arch.

  • The case presented an atypical progression where respiratory symptoms manifested before overt swallowing difficulties.

    • Implications:

    • This case highlights the importance of considering vascular ring anomalies in young animals with chronic respiratory signs, even without obvious dysphagia.
    • Understanding the varied clinical presentations of persistent right aortic arch is crucial for timely diagnosis and intervention in veterinary patients.
    • The unusual sequence of symptoms underscores the complex interplay between esophageal obstruction, regurgitation, and secondary respiratory compromise.
