Carotid Plaque Characterization by Virtual Histology Intravascular Ultrasound Related to the Timing of Carotid Intervention

Purpose To determine the incidence of vulnerable plaques characterized by virtual histology intravascular ultrasound (VH IVUS) in patients with severe internal carotid artery (ICA) stenosis and its relationship to the timing of protected carotid artery stenting (CAS). Methods The study included 141...

Description
Summary:Purpose To determine the incidence of vulnerable plaques characterized by virtual histology intravascular ultrasound (VH IVUS) in patients with severe internal carotid artery (ICA) stenosis and its relationship to the timing of protected carotid artery stenting (CAS). Methods The study included 141 patients (119 men; mean age 66.9 ± 9 years) with severe ICA stenosis undergoing CAS with cerebral protection. Patients were classified in 3 groups: 39 symptomatic early CAS (
