Dysphagia lusoria and segmental aperistalsis in the upper third of the esophagus

An aperistaltic zone located in the upper third of the esophagus was present in a young woman with dysphagia, who had undergone surgical treatment for dysphagia lusoria 3 months before. The segmental absence of contraction in the upper third of the esophagus was the most probable cause for the persistence of dysphagia, and could have resulted from damage related to compression or to surgical intervention in the area.
