microangiopathy

[mī′krō·an′jē·op′əthē]
Etymology: Gk, mikros + angeion, vessel, pathos, disease
a disease of the small blood vessels. Examples are diabetic microangiopathy, in which the basement membrane of capillaries thickens, and thrombotic microangiopathy, in which thrombi form in the arterioles and capillaries.

microangiopathy

Any defect of very small blood vessels, usually capillaries, which is most common in diabetes, especially if poorly controlled. Despite thickening of the vascular basement membranes by a hyaline-like material, which corresponds to advanced glycosylation end products (AGEs), the vessels are leaky and allow transvascular passage of plasma proteins. AGEs or advanced diabetic microangiopathy-induced ischaemia directly impacts on the retina, the kidney and the peripheral nerves.

microangiopathy

Vascular disease Any defect of very small blood vessels, usually capillaries, which is most common in DM. See Diabetic microangiopathy.
