[Percutaneous transluminal angioplasty using a stent for an aberrant left subclavian artery stenosis with a right-sided aortic arch: a case report].

An 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.
