Imaging Carotid Atherosclerosis Plaque Ulceration: Comparison of Advanced Imaging Modalities and Recent Developments

Abstract: SUMMARY: Atherosclerosis remains the leading cause of long-term mortality and morbidity worldwide, despite remarkable advancement in its management. Vulnerable atherosclerotic plaques are principally responsible for thromboembolic events in various arterial territories such as carotid, coronary, and lower limb vessels. Carotid plaque ulceration is one of the key features associated with plaque vulnerability and is considered a notable indicator of previous plaque rupture and possible future cerebrovascular eve… Show more

“…However, the invasive nature, the need for ionizing radiation, and the limited power to identify plaque ulceration—which is considered a key feature associated with plaque vulnerability and a notable indicator of previous plaque rupture and possible future cerebrovascular events—resulted in progressive replacement by non-invasive technology. 27 Sonography (and Doppler ultrasonography) was introduced as the first non-invasive platform for carotid artery imaging in the clinical setting. This technology provides relevant information in a low-cost, fast, and safe manner, including degree of stenosis, heterogeneity of the plaque, luminal flow, and the presence of very large ulcerations.…”

“…Por lo tanto, podemos concluir que las placas vulnerables se caracterizan por: tener un capuchón fibroso delgado, un centro necrótico grande rico en lípidos, hemorragia intraplaca e inflamación activa intraplaca. 1, 3,4,8,9,10,11…”

“…Ésta modalidad combina el modo B y da información sobre la velocidad del flujo de sangre, es una buena herramienta de tamizaje; sin embargo tiene ciertas limitaciones a la hora de cuantificar la estenosis como son: reproducibilidad, artefacto por calcificación, dificultad para diferenciar entre oclusión subtotal o total. 9,11 Ésta modalidad también despliega el promedio de cambios en la frecuencia de ecos que se devuelven de objetos en movimiento; principalmente glóbulos rojos. La escala de color se escoge; puede ser desde dos colores (rojo y azul) a una paleta de arcoiris.…”
