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. [1] It can be contrasted to macroangiopathies such as atherosclerosis , where large and medium-sized arteries (e.g., aorta , carotid and coronary arteries ...
There are two types of angiopathy: macroangiopathy and microangiopathy. [2] In macroangiopathy, atherosclerosis and a resultant blood clot forms on the large blood vessels, sticks to the vessel walls, and blocks the flow of blood. Macroangiopathy in the heart is coronary artery disease; in the brain, it is cerebrovascular disease.
However, the brain may appear normal in the neonatal period. The calcifications are visible both with computed tomography and with magnetic resonance imaging . Magnetic resonance imaging shows additionally diffuse or patchy white matter changes, especially in the periventricular region, the thalami and the internal capsule .
Congenital diseases are medical conditions that are present at birth that may be associated with or inherited through genes. [16] Examples of congenital cerebrovascular diseases include arteriovenous malformations, germinal matrix hemorrhage, and CADASIL (cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy).

Compared to the National Early Warning Score from the UK, Q-ADDS had a higher rate of prediction of deterioration (46.5% Q-ADDS vs 40.8% NEWS) but a higher rate of false-positives (3.2:1 Q-ADDS vs 2.4:1 NEWS). [12] The efficacy of EWSs in improving patient outcomes is also reliant on a number of personal and structural factors.
“A medical assistant may be in the room but have their back to the patient or aren’t paying attention because they're taking notes,” she says. “A chaperone is a patient advocate who is ...
Thrombotic microangiopathy (TMA) is a pathology that results in thrombosis in capillaries and arterioles, due to an endothelial injury. [1] It may be seen in association with thrombocytopenia , anemia , purpura and kidney failure .
Conditions that impair blood vessels in the brain and therefore interfere with oxygen delivery to the brain [3] Risk factors: High blood pressure, high cholesterol, atrial fibrillation, diabetes [3] Diagnostic method: Lab test, neuroimaging test, neuropsychological testing [5] Differential diagnosis: Alzheimer’s disease [5] Treatment ...
