Contrast-enhanced ultrasound assesses neovascularization in carotid atherosclerotic plaques / 国际脑血管病杂志

ABSTRACT

Carotid atherosclerotic stenosis is associated with an increased risk of stroke onset and recurrence. The histopathological features of the vulnerable plaques include the presence of lipid necrotic cores, intra-plaque hemorrhage, intra-plaque neovascularization, active inflammation, and thin/ruptured fibrous caps. The intraplaque neovascularization may promote the intra-plaque hemorrhage, and is associated with the rupture of plaques, the formation of local emboli, and the distal embolism. Contrast-enhanced ultrasound can identify the vulnerable carotid plaques by evaluating intraplaque neovascularization.
