FIG 3. A and B, Illustration of the buddy wire technique in an 82-year-old woman.
A, Left, Left carotid angiogram shows near occlusion of the ICA and significant tortuosity of the distal ICA. Initial attempt to pass the temporary occlusion catheter of the GuardWire protection system through the stenosis was unsuccessful due to the severity of the stenosis. Middle, Angiogram shows a buddy wire positioned through the stenosis and the distal tortuous segment of the ICA. Blood flow through the subocclusive stenosis is hindered by the guidewire with the predilation balloon. Right, Angiogram shows the stenosis predilated with a 3 x 20-mm coronary balloon.
B, Left, Angiogram shows the inflated balloon of the temporary occlusion catheter positioned distal to the stenosis along the buddy wire. Middle, Angiogram shows the postdilated stent. The buddy wire was removed before deployment of the 10 x 24-mm Wallstent. Right, Angiogram obtained after carotid artery stent placement.
