FIG 2. Case 2, 60-year-old man with SS from the ipsilateral VA originating from the very proximal segment of the SCA.
A and B, Selective left SCA angiograms show a proximally originated left VA with 70% stenosis at the origin, occlusion of the left SCA, and collateral filling from the ipsilateral VA.
C, Postoperative selective left subclavian angiogram demonstrates good recanalization of the left SCA and no residual stenosis at the left VA origin.
