B, Proximal end of the uninflated balloon anchored in the guiding catheter. The stent segment remains outside the catheter. C, The stent opening at first inflation resembles the shape of a dumbbell. D, The guiding catheter is pulled back to allow a second full inflation. E, Complete resolution of the stenosis.

View larger version (106K): [in this window] [in a new window]   Fig 2. Case 9. A, The guiding catheter is steered into the right extracranial VA with the aid of a partially re-inflated balloon within the stent at the VAO. B, The balloon was deflated as the catheter envelopes it within the VAO stent. C, The tip of the guiding catheter is placed at the distal V2 segment for stent placement of a short-segment stenosis (80%) in the BA. D, Resolution of the stenosis.
