Right aortic arch is a rare congenital anomaly. We present a case of staged angioplasty for stenosis of the right internal carotid artery of the right aortic arch.
A 66-year-old man visited our hospital after experiencing inarticulation. Magnetic resonance imaging (MRI) of the head showed acute cerebral infarction in the right middle cerebral artery region, and magnetic resonance angiography (MRA) showed poor visualization of the right internal carotid artery. Cerebral angiography revealed severe stenosis of the right internal carotid artery and right aortic arch. We performed a staged angioplasty to avoid postoperative hyperperfusion syndrome.
It is crucial to have sufficient knowledge of the anatomy of the right aortic arch, keeping it in mind constantly since it may be rarely detected during cerebral angiography and emergency catheter treatment, which requires ingenuity for procedure and device selection.
