dysphagia lusoria

David Bayford called it dysphagia lusoria; because in latin, lusus naturæ means sports of nature or natural anomaly.

Dysphagia due to an aberrant right subclavian artery is termed dysphagia lusoria.

Dysphagia caused by a similar mechanism is referred to as dysphagia aortica, or, in the case of subclavian artery aberrancy, as dysphagia lusoria.

In 1761, while still an apprentice surgeon, he made his discovery of the unique and bizarre cause-compression of the oesophagus by an aberrant right subclavian artery-of a fatal case of obstructed deglutition for which he coined the term dysphagia lusoria and for which he is eponymously remembered.
