May 7, 2024 · The vasa vasorum represents the supporting microvasculature of the larger caliber arteries and veins of the body. The vasa vasorum has two subtypes in humans 2,3: Sites that vasa vasorum occur 2-5: Vaso vasorum translates to "the vessel of vessels" in Latin.

Aug 30, 2007 · Morphological studies with ultrasound have identified echographic plaque characteristics, beyond the severity of stenosis, that reflect a higher risk of vulnerability, so defining the “unstable” plaque. 1 Adventitial vasa vasorum and plaque neovascularization have been well established and confirmed in histological studies as predictors of ...

New data suggest that contrast-enhanced ultrasound (CU) imaging of the carotid arteries enhances luminal irregularities (i.e., ulcers and plaques), improves near-wall, carotid intima-media thickness, and uniquely permits direct, real-time visualization of neovasculature of the atherosclerotic plaque and associated adventitial vasa vasorum.

Vasa vasorum proliferate in the setting of intimal hypoxia and inflammation in atherosclerosis (B). Intimal neovascularization and hemorrhage expand the necrotic core and induce rapid plaque progression (C).

Jan 11, 2013 · We report an elderly patient presenting with a stroke and also hemolytic anemia secondary to mitral and tricuspid valve repair 3 years earlier, in whom two-dimensional transesophageal echocardiography (2DTEE) suspected a fistula into the pulmonary artery (APAF) from the posterior wall of the aortic arch.

Aug 1, 2008 · In this Review, we discuss the clinical implications of vasa-vasorum-derived plaque neovascularization and the detection of these angiogenic vessels using contrast-enhanced,...

Nov 12, 2009 · Contrast-enhanced carotid ultrasound (CECU) provides direct visualization of the adventitial vasa vasorum and intraplaque neovascularization, 9–12 using the fact that contrast agents microspheres are ideal intravascular tracers, thus permitting a noninvasive assessment of the dynamic spatial and temporal heterogeneity of the intraplaque ...

Proliferation of the adventitial vasa vasorum (VV) is inherently linked with early atherosclerotic plaque development and vulnerability. Recently, direct visualization of arterial VV and intraplaqu...

A string-like vasa vasorum is an entirely different entity — it is a collateral channel within the wall of a completely occluded vessel, reconstituting the distal aspect of the native artery beyond its occlusion.

Vasa vasorum are networks of small blood vessels that supply the walls of large blood vessels, such as elastic arteries (e.g., the aorta) and large veins (e.g., the venae cavae). The name derives from Latin 'the vessels of the vessels'.
