“Catheter Push” Technique to Open Flow Diverter
A 55-year-old female presented with left side facial pain and recent onset left sixth and partial third nerve palsies. Cross-sectional imaging revealed a giant cavernous aneurysm. DSA and 3D angiography revealed a giant partially thrombosed internal carotid artery (ICA) aneurysm along with a small ophthalmic aneurysm (Fig. 30.1a, b). Balloon test occlusion revealed inadequate collateral flow. Patient was planned for flow diverter placement.
