Stiff Guide Technique: Technical Report and Illustrative Case

Images from the case of a 60-year-old man with a history of transient ischemic attacks consisting of left-sided amaurosis fugax and slurred speech.

A, Angiogram of the left ICA shows severe stenosis of third and fourth portions of the left cavernous carotid artery with ulceration.

B, Image shows buckling of the sheath into the aorta with a standard glide wire in place as a stiffening wire.

C, Left carotid artery sheath with Stiff Shaft glide wire, balloon/stent catheter, and Agility wire. (Balloon/stent catheter and Agility wire were radiolucent except at the tip and are therefore not visualized on this image.)

D, Angiogram of the left ICA, obtained after stent placement. Minimal residual stenosis is seen. The previously seen ulceration is no longer seen. Improved flow in the anterior cerebral artery and some filling of the posterior cerebral artery are shown.
