Abstract: | A right-sided aortic arch with an aberrant left subclavian artery is a rare anatomical variation. We report a case treated
with carotid artery stenting (CAS) for a patient with a right-sided aortic arch with an aberrant left subclavian artery. A
72-year-old man presented right hemiparesis due to acute brain infarction. Neck CT angiography showed 70% stenosis in the
left internal carotid artery (ICA). We diagnosed acute brain infarction as artery-to-artery embolism due to ICA stenosis and
decided to perform carotid artery stenting (CAS) for symptomatic ICA stenosis. CT angiography to evaluate an access route
to the lesion incidentally showed the right-sided aortic arch with an aberrant left subclavian artery. An intraoperative aortogram
showed a right-sided aortic arch. The guiding catheter was carefully introduced up to the left common carotid artery. CAS
was performed with a proximal balloon and distal filter protection. The stenotic area was restored, and the patient was discharged
without suffering recurrent attacks. Although a right-sided aortic arch with an aberrant left subclavian artery is a very
rare anatomical variation, it can be encountered in neuroendovascular treatment, and therefore knowledge of this anatomical
variation is important. |
