Dysphagia lusoria
Dysphagia lusoria (or Bayford-Autenrieth dysphagia) is abnormal condition characterized by difficulty in swallowing caused by aberrant right subclavian artery
During development of aortic arch, if the proximal portion of the right fourth arch disappears instead of distal portion, the right subclavian artery will arise as the last branch of aortic arch. It then courses behind the esophagus (or rarely in front of esophagus, or even in front of trachea) to supply blood to right arm. This causes pressure on esophagus and results in dysphagia. It can sometimes result in upper gastrointestinal tract bleeding
