Stent implantation of multichanneled pseudoocclusion of the internal carotid artery

Multichanneled pseudoocclusion (MCPO) is a severe stenosis with more than 95% of the carotid bulb with multichannels in the stenotic segment. This report describes successful carotid stent implantation in five patients with MCPO of the internal carotid artery. Probing of the micro-guide wire through the channel with support of the microcatheter made subsequent angioplasty and stent placement possible without procedure-related complications. There was neither additional stroke nor restenosis during a follow-up period of 6-54 months.
