Is optical coherence tomography a coherent strategy for carotid artery stenting?

Optical coherence tomography (OCT) is rarely necessary to guide clinical decisions about the appropriateness of carotid revascularization. For carotid artery stenting (CAS), computed tomography angiography is the best imaging tool to assess arch, carotid, and lesion-specific anatomy, including vessel dimensions and calcification. OCT is a coherent strategy after CAS to assess ambiguous angiographic findings and to guide appropriate therapy for dissection, thrombosis, and plaque prolapse.
