We report the observation of a patient suffering from dysphagia lusoria, a dysphagia caused by an anomalous form of the right subclavian artery. The diagnosis was confirmed by aortic arch angiography and cine-oesophagogram. Oesophageal manometric study revealed segmental hypoperistalsis and anti-peristalsis. Dysphagia disappeared with cisapride. This observation suggests that dysphagia lusoria is caused by oesophageal motility disorders and not by vascular compression.
