Case report highlights recurrent cerebral infarctions in an elderly man due to compression by swallowing, suggesting stenting as a potential solution.
An 81-year-old man presented with recurrent cerebral infarctions despite the administration of dual antiplatelet therapy. Imaging revealed a severely stenotic, calcified, and aberrant right subclavian artery (ARSA) closely adjacent to the esophagus. Cerebral infarctions are repeatedly triggered by swallowing, and mechanical compression of the ARSA by food passage is considered to be a mechanism of cerebral infarction. Stenting of the ARSA and the left subclavian artery was performed to prevent any further events.
