Percutaneous transluminal angioplasty using kissing balloon technique for carotid bifurcation stenoses coupled with the proatlantal intersegmental artery: a case report.

A 65-year-old man, who suffered from recurrent syncopal attacks after a minor stroke, was treated by percutaneous transluminal angioplasty using the kissing balloon technique (KBT) in which two angioplasty balloons were inflated simultaneously for the right carotid bifurcation stenoses. Because they involved the right internal carotid artery and the right external carotid artery coupled with the right proatlantal intersegmental artery, neither of them should close after the angioplasty. Bifurcation stenoses were sufficiently dilated with KBT and no syncopal attacks have recurred since the treatment.
