We report a simple endovascular repair for symptomatic aberrant right subclavian artery (ARSA) in an 11-year-old girl. She had undergone tracheostomy due to hypoxic encephalopathy after cardiac surgery and suffered from dyspnea. Computed tomography revealed tracheal stenosis caused by a vascular ring made with an ARSA and the right common carotid artery. Transcatheter ARSA embolization using an Amplatzer vascular plug and coils was performed. Symptoms improved within a few days after this intervention and no complications such as upper extremity ischemia were encountered. Computed tomography showed the ARSA around the trachea had reduced in size and tracheal stenosis was improved.
