Is the Adventitial Vasa Vasorum in Vulnerable Carotid Plaques Increased or Decreased? [PDF]

Advanced Ultrasound in Diagnosis and Therapy
Background Intraplaque neovascularization is a biomarker of vulnerable plaque. However, no data are available whether the increase in neovascularization within carotid plaques is a result of ischemia or an increase in adventitial vasa vasorum (VV ...

Studying the Factors of Human Carotid Atherosclerotic Plaque Rupture, by Calculating Stress/Strain in the Plaque, Based on CEUS Images: A Numerical Study

Frontiers in Neuroinformatics, 2020
Carotid plaque neovascularization is one of the major factors for the classification of vulnerable plaque, but the axial force effects of the pulsatile blood flow on the plaque with neovessel and intraplaque hemorrhage was unclear.

The Differences Between Neovascularization of Chronic Total Occlusion and Intraplaque Angiogenesis

JACC: Cardiovascular Imaging, 2010
A number of patients with coronary artery disease present with chronic total occlusion (CTO), in which the extent of distal reperfusion and myocardial salvage is dependent on collateral circulation.

Association between intraplaque neovascularization assessed by contrast-enhanced ultrasound and the risk of stroke [PDF]

Clinical Radiology, 2020
To determine the cut-off value of the area ratio under the curve (ARUC) for predicting symptoms of stroke.Contrast-enhanced ultrasound was used to analyse intraplaque neovascularization (IPN). The correlations between the ARUC and risk factors of stroke were examined.

Contrast-enhanced ultrasonography of the carotids [PDF]

Ultrasonography, 2015
Contrast-enhanced ultrasonography of the carotids has recently emerged as a complementary examination to conventional carotid Doppler ultrasonography. It is an examination providing improved visualization of the vascular lumen, more accurate and detailed

Characteristics and evaluation of atherosclerotic plaques: an overview of state-of-the-art techniques

Frontiers in Neurology, 2023
Atherosclerosis is an important cause of cerebrovascular and cardiovascular disease (CVD). Lipid infiltration, inflammation, and altered vascular stress are the critical mechanisms that cause atherosclerotic plaque formation.

Dual-energy computed tomography iodine maps for visualizing enhancement and estimating characteristics in plaques

Radiology Case Reports
Distal embolism causing acute ischemic events due to rupture of vulnerable plaques can occur during endovascular therapy, necessitating careful treatment and technique selection. Intraplaque neovascularization (IPN) is a key factor in plaque instability.

Mechanistic Insights Into the Association Between Gut Microbiota Diversity and Atherosclerosis, Acute Coronary Syndrome, and Peripheral Arterial Disease Progression

Clinical Cardiology, Volume 49, Issue 9, September 2026.
Proposed gut‐vascular framework linking microbial ecology to atherosclerotic disease. Diet and related exposures shape dysbiosis or microbial resilience; resulting changes in SCFAs, TMAO, bile acids, and LPS may modulate endothelial function, immune activation, and platelet activity, contributing to atherosclerosis, ACS, and PAD.

Molecular Imaging of Inflammation and Intraplaque Vasa Vasorum

, 2013
Intraplaque neovascularization is a strong predictor of intraplaque hemorrhage and subsequent plaque rupture. Intraplaque neovascularization is caused by angiogenesis under the influence of hypoxic and inflammatory stimuli.
