Selective cannulation of the right common carotid artery was performed using a 5F Headhunter catheter. After cannulation, a 0.035 inch stiff wire was inserted into the external carotid artery. A 7Fr, 90 cm long, shuttle sheath was positioned in the right common carotid artery over the stiff wire. Then, 0.014 inch Emboshield filer wire was advanced beyond the critical stenosis. And the emboshield filter was positioned in the distal ICA (Figure 2). The lesion was predilated with an ultrathin 4.0 x 20 mm balloon at 6atm. Following angiogram showed a significant residual stenosis at the right proximal ICA (Figure 3). A self-expanding, 6mm x 48mm, carotid wallstent was positioned and expanded from the right common carotid artery to the proximal ICA. Following angiogram revealed moderate stenosis of intrastent portion. Therefore, adjunctive balloon dilation was performed with a Powerflex 6.0mm x 20mm balloon at 10 atm. The final result is shown in Figure 4. A small amount of atheroembolic debris was captured in emboshield filter device. The patient had no neurological deficit and was discharged two days later without event.
