Small Brain Vessels Disease

Hemodynamics of Large and Small Vessels in Peripheral Vascular Disease.

N this study, an attempt has been made to evaluate differentially the hemodynamics of the large artery, small artery, and venous segments of the peripheral circulation in normal persons and in patients with peripheral vascular disease. When only gross evaluations of flow are made, it is impossible to pinpoint the mechanism causing the observed deficiency. A more thorough knowledge of the basic ...

Book Review: “Cerebral Small Vessel Disease”. What’s the Big Deal about Small Vessels?

Cerebral small vessel disease is perhaps among the most common pathologies in the aging brain, primarily affecting the small perforating arteries and arterioles in the cortex and underlying structures of the white and deep gray matter. Small vessel disease includes hypertensive arteriopathy (arteriolosclerosis, fibrohyalinosis, or lipohyalinosis) and cerebral amyloid angiopathy (injury to the v...

Brain Atrophy and Cerebral Small Vessel Disease

Background and Purpose—Cerebral small vessel disease (SVD) is the most common cause of vascular dementia. Interest in the use of surrogate markers is increasing. The aims of this study were to determine if brain volume was different between patients with SVD and control subjects, whether it correlated with cognition in SVD, and whether changes in brain volume could be detected during prospectiv...

Coronary microvasculature: small vessels with large impact.

α1- Adrenoceptors in Small Blood Vessels

The relative importance of the different α1-adrenoceptor subtypes in regulation of peripheral resistance and systemic arterial blood pressure is not clear, as the contribution of different subtypes to vasoconstriction varies with species and resistance vascular bed [1,2]. A further factor which may influence the subtypes involved in vasoconstriction physiologically is the manner of receptor act...
