Evaluation of Below-the-Knee Drug-Eluting Stents With Frequency-Domain Optical Coherence Tomography: Neointimal Hyperplasia and Neoatherosclerosis

Abstract

FD-OCT of the infrapopliteal arteries following DES placement is safe and feasible and may demonstrate features of developing neointimal neoatherosclerosis. The latter might play a key role as a mechanism of below-the-knee ISR and warrants further investigation.
