FIG 2. A 72-year-old woman with recurrent stenosis after angioplasty and stent placement of a high-grade stenosis in the proximal right subclavian artery.

A, Injection of the guide catheter in the innominate artery before angioplasty of the right vertebral artery origin. The lumen of the stenotic segment is nearly the same diameter as that of the guide catheter. Another stenosis is in the right subclavian artery distal to the vertebral artery.

B, Innominate injection shows extravasation of contrast material after the second angioplasty of the right subclavian artery.

C, Arch aortogram the following day demonstrates a pseudoaneurysm.
