(a) and (b) Digital subtraction angiography images showing the navigation of the balloon catheter over a Synchro guidewire. It is important to place the wire distally in the middle cerebral artery branches to give enough support, specially in larger broad-neck aneurysms. (c) After deployment, the flow diverter is seen in place but narrowing of its intermediate portion is visible. (d) Balloon angioplasty is performed throughout the stent to improve expansion of the proximal and intermediate portions of the stent.
