AbstractAn aberrant left subclavian artery is a rare variant that has been reported to coexist with the right-sided aortic arch in many cases. We encountered a case in which percutaneous transluminal angioplasty using a stent was performed for an aberrant left subclavian artery and left carotid artery. The patient was a 63-year-old man in whom left carotid artery stenosis and abnormal flow pattern of the left vertebral artery was accidently found during an ultrasound screening of his carotid artery. The right-sided aortic arch with the aberrant left subclavian artery was revealed by a cerebral angiogram via the right femoral artery. Despite difficulty in inserting a catheter at the origin of the aberrant left artery, the treatment was completed successfully. To our knowledge, endovascular treatment for an aberrant left subclavian artery has not been reported until date.
