    An Optical Coherence Tomography Assessment of Stent Strut Apposition Based on the Presence of Lipid-Rich Plaque in the Carotid Artery

    Purpose: To evaluate the rate of stent malapposition, plaque prolapse, and fibrous cap rupture detected by optical coherence tomography (OCT) after carotid artery stenting (CAS) based on the presence of lipid-rich plaque, which may be associated with acute stent thrombosis. Methods: A retrospective study was conducted involving 26 consecutive patients who underwent CAS with OCT imaging acquired before stent deployment and after stent dilation. Adequate imaging quality could not be obtained in 6 patients (out-of-screen images and residual blood), which left 20 patients (mean age 63 years; 13 men) for analysis. Plaque characteristics were determined from 500 selected OCT cross ...
