Carotid plaque ulceration or surface irregularity is characterized as an indentation, fissure, or erosion on the luminal surface of a plaque, exposing a portion of the inner plaque to direct contact with the circulating blood. 10 Various factors are involved in the pathogenesis of ulceration, including the accumulation of inflammatory cells ...

2008年9月2日 · Here, we report the first case of healing of human carotid plaque ulceration over a short time period. The healed plaque was covered with mainly type I and type III collagen.

Ulceration is a frequent finding in carotid plaques/ but the role of ulceration as a source of artery-to-artery embolism is unclear. Controversy exists because of the difficulty in establishing a uniform definition of ulceration and because of the limited diagnostic accuracy of radio-logical techniques.

Irregularities in the surface of an atheromatous plaque located in the right carotid bulb. Identified greater irregularity that must match a small plaque ulceration, seen also in the B-mode cross section image. On the left bulb there is a soft atheromatous plaque with smooth surface.

2017年2月3日 · Subjects that will be discussed include the ulcer’s definition and classification, clinical significance and imaging. Imaging findings of ulcerated carotid plaques will be illustrated with diagrammatic representations and educational images, …

2010年12月23日 · Symptomatic carotid artery plaque ulceration is associated with distinct plaque components such as a large lipid-rich necrotic core (LR-NC) in ischemic stroke patients with a ≥50% carotid stenosis.

2021年7月21日 · Mayo Clinic uses state-of-the-art carotid plaque imaging to assess an individual's risk of stroke. Mayo's robust MRI protocols facilitate the detection of specific carotid plaque components associated with ischemic events, even …

In patients with carotid artery stenosis, carotid plaque ulceration can be identified in approximately one in five patients by ultrasound. Overall, the presence of carotid plaque ulceration was associated with an increased risk of future stroke.

• US is the first-line modality for carotid disease and identification of ulcerations. • The administration of microbubbles increases US accuracy for diagnosis of carotid ulceration. • MDCTA and MRA are valuable for diagnosing ulceration and evaluating plaque composition.

The purpose of this study was to evaluate the role and the diagnostic efficacy of multidetector row CT angiography (MDCTA) and ultrasound (US) echo color Doppler (US-ECD) in the study of patients with carotid plaque complicated by ulceration through …
