- Fig 1.
Angioscopic observation with distal protection (A) with PercuSurge GuardWire and (B) with the Parodi Antiemboli System. CCA signifies common carotid artery; ICA, internal carotid artery; ECA, external carotid artery; PS, PercuSurge GuardWire; FC, fiber catheter AS-003 with aspiration catheter; PAES, Parodi Antiemboli System.
- Fig 2.
Angioscopic image of the internal carotid artery in case 16 clearly shows stent attachment to the wall.
- Fig 3.
Angioscopic image of the internal carotid artery in case 7. First debris (red arrowheads) detaches from the atherosclerotic carotid wall and then floats to the distal side with time (A–E). Next debris (yellow arrowheads) also detaches from the carotid wall (D–F).
- Fig 4.
Angioscopic image of the internal carotid artery proximal to the stent in case 2 shows the intimal flap (arrows) fluttering from the arterial wall.
