New triple coaxial catheter system for carotid angioplasty with cerebral protection.

i I I D B c A supraaortic arteries and, particularly, to carotid bifurcations [4-17] . We previously reported an angioplasty technique involving temporary occlusion of the internal carotid artery to prevent cerebral embolization during manipulation of ulcerated plaques [18]. The present article describes a new triple coaxial catheter system (Schneider [Europe] AG, Zurich, Switzerland) (Fig. 1 ), which simplifies this technique and allows angioplasty with a "cerebral protection" based on the same concept of distal temporary occlusion of the internal carotid artery.
