A 74-year-old man presented with left-sided monocular visual loss as a result of branch retinal artery occlusion. Carotid ultrasonography showed mild (20%) left carotid artery stenosis but no embolic source was identifi ed. MRI of the carotid artery showed a large atherosclerotic plaque at the origin of the left internal carotid artery, despite only ...

To the Editor. —We found the hypothesis of carotid plaque disruption proposed by Fisher et al 1 interesting but at variance with our clinicopathologic data in Toronto, Canada. The authors emphasize surface events in carotid plaques, but we believe that events within the body of the plaque may be equally, or even more, important.

Imaging of Carotid Plaque Angiogenesis
Cerebrovascular Diseases, 2009Currently, characterization of the vulnerable plaque is a hot research topic as a more adequate strategy for preventing cerebrovascular events is being sought. Histological studies have recognized that plaque inflammation and the presence of adventitial vasa vasorum, intimal angiogenesis and plaque neovascularization are strong predictors of ...

Carotid Plaque Morphologic Characteristics
Perspectives in Vascular Surgery and Endovascular Therapy, 2006Carotid artery atherosclerosis is predominantly believed to mirror atherosclerosis elsewhere in the body. Endothelial injury results in expression of cell surface adhesion molecules with expression of sequence of genes involved in the inflammatory pathway and expression of proinflammatory cytokines.

Ultrasonographic Characterization of Carotid Plaques
Ultrasound in Medicine & Biology, 1998The composition of atherosclerotic plaques in the carotid artery is assumed to be related to the development of neurological symptoms. The echo patterns produced by B-mode ultrasound may be of use in the assessment of the plaques' composition. It is suggested that fibrotic and "stable" plaques are more echogenic than lipid/hemorrhagic and echolucent or

Carotid endarterectomy for high plaques
The American Journal of Surgery, 1989Seventeen instances of high plaque (plaque extending up to the level of the second cervical vertebra) were encountered out of a total of 454 carotid endarterectomies (3.7 percent). With careful dissection and knowledge of anatomy superior to hypoglossal nerve, carotid endarterectomy was accomplished without resorting to mandibular subluxation or ...

Measurement of Carotid Plaque Burden
JAMA Neurology, 2015Purpose of reviewTo describe the uses of measurement of carotid plaque burden, as total plaque area (TPA), total plaque volume (TPV), and vessel wall volume (VWV), which includes plaque burden and wall volume.Recent findingsMeasurement of plaque burden is useful for risk stratification, research into the genetics and biology of atherosclerosis, for ...

Histologic characterization of carotid plaques
Cardiovascular Pathology, 1994From January 1988 to December 1989, we performed a total of 278 carotid thromboendarterectomies. The plaque was systematically prepared for anatomicopathological analysis by standard light microscopic techniques. We sought to correlate the histology of the endarterectomy specimen with the clinical data.

Carotid Endarterectomy for Asymptomatic Plaque
Neurologic Clinics, 2006Statistical correlations are linear noninteractive relationships, but the dynamics of causation are nonlinear and involve complex interactions where variables change through their effect on one another and interact with the context of the patient over time. The discovery and interpretation of plaque vulnerable features in the individual patient are not
