Lipid-core plaque (LCP) detected by near-infrared spectroscopy (NIRS) in the coronary arteries is associated with acute coronary syndromes (ACS) (1,2). Analogous to its role in acute coronary syndromes, LCP in the carotid arteries has been implicated in the pathogenesis of stroke (3). It has not been previously demonstrated whether NIRS, which was developed to identify LCP in the coronary arteries, can also detect LCP in the carotid arteries.
We performed NIRS in the carotid arteries of patients with severe carotid stenosis after deployment of a distal embolic protection device but prior to stenting. The present observations represent the first-in-man use of NIRS to characterize carotid artery plaque in vivo and demonstrate the feasibility of carotid NIRS imaging (Figures 1 and 2⇓⇓). Future studies are needed to determine whether NIRS can predict procedural complications during carotid stenting, influence the selection of patients for stenting or endarterectomy, and predict future neurologic events.
