ABSTRACT
The patient received no sedatives as premedication. A 6 Fr sheath was placed in the right common femoral artery. An arch aortogram and four-vessel carotid and vertebral angiography with intracerebral views were performed with a pigtail and a 125-cm-long 6 Fr JR-4 catheter. Baseline angiography confirmed a 99% stenosis of the right internal carotid artery (Figure 1.1).
