Aberrant right subclavian artery (ARSA) is asymptomatic in most cases. This variant anatomy can cause dysphagia in elderly patients. Impaction of foreign body in the esophagus is rarely the presenting symptom of ARSA. We present an eighty four years old patient who first presented with esophageal foreign body impaction and was diagnosed with an aberrant right subclavian artery compressing the esophagus just below the site of impaction.We assume that the exact place of impaction was not incidental and that a relative narrowing of the esophagus caused by the vascular anomaly is responsible for this specific presentation.
异常右锁骨下动脉（ARSA）在大多数情况下是无症状的。这种变异的解剖结构可能导致老年患者出现吞咽困难。食管异物嵌顿很少是 ARSA 的表现症状。我们报告一例 84 岁患者，其最初表现为食管异物嵌顿，并诊断为异常右锁骨下动脉压迫食管，位于嵌顿部位下方。我们假设确切的嵌顿部位并非偶然，而是由血管异常引起的食管相对狭窄导致了这种特定的表现。
