[Subclavian steal syndrome associated with the right aortic arch in a @entity1 with XXXX : case report].

@entity1 @entity2838 @entity3791 @entity9468 @entity3526
We report an adult case who presented @entity9468 attacks due to @entity3526 associated with the right aortic arch in a @entity1 with @entity2838 . A 29-year-old male diagnosed as having @entity2838 developed frequent @entity9468 attacks and was admitted to our hospital. Blood pressure of the left arm was 20 mmHg lower than that of the right arm. Aortagraphy showed that he had a right aortic arch and isolation of the left subclavian artery. Right vertebral angiography opacified the left vertebral artery and the subclavian artery in retrograde fashion, suggesting subclavian steal phenomenon. Blood flow studies disclosed impaired reactivity to @entity3791 in the bilateral cerebellar hemispheres. We successfully carried out left common carotid artery-transverse cervical artery bypass. Postoperative angiography confirmed the patency of the graft and the disappearance of subclavian steal phenomenon. Vasoreactivity to @entity3791 normalized in the cerebellum. Vertigo attacks were not noted during the one-year follow-up period.
