title: Aberrant right subclavian artery--three case reports.
abstract: Conventional angiography detected three cases of aberrant right subclavian artery. A 51-year-old female presented with a small infarction in the left medulla oblongata and severe stenosis of the left subclavian artery. A 59-year-old female presented with multiple cerebral infarctions and severe atherosclerotic changes in the intracranial arteries. A 58-year-old female presented with aneurysmal subarachnoid hemorrhage. The aberrant right subclavian artery was asymptomatic in all patients. Knowledge of this anatomical variation is important in diagnostic neuroangiography and interventional neuroradiology.
