Microangiopathy

Common card · No. 318758

Microangiopathy (also known as microvascular disease, small vessel disease (SVD) or microvascular dysfunction) is a disease of the microvessels, small blood vessels in the microcirculation. It can be contrasted to macroangiopathies such as atherosclerosis, where large and medium-sized arteries (e.g., aorta, carotid and coronary arteries) are primarily affected. Small vessel diseases (SVDs) affect primarily organs that receive significant portions of cardiac output such as the brain, the kidney, and the retina. Thus, SVDs are a major etiologic cause in debilitating conditions such as renal failure, blindness, lacunar infarcts, and dementia.
