Dysphagia lusoria means dysphagia

.Dysphagia lusoria: It is a congenital vascular anomaly of the aoic root. Aoic arch anomalies are - double arch (40%), right arch and left ligamentum aeriosum (25%), anomalous innominate or common carotid aery or aberrant right subclan aery (10%). It is due to the disappearance of proximal right 4th aoic arch instead of the distal poion. All patients having this anomaly (dysphagia lusoria) have got an aberrant right subclan aery in a transposed position arising from descending aoa that courses posterior to the oesophagus. Often there will be a complete vascular ring around trachea and oesophagus. It is categorised based on their specific subclan anomaly - depends on the presence of an aneurysm, occlusive disease and compression. Commonly they are asymptomatic. Presentations may be dysphagia, chest pain, stridor, wheeze, recurrent respiratory infection (usually presents after the age of 40). Ref: SRB&;s manual of surgery,3 rd ed, pg no 720
