Angiopathy

Angiopathy

Angiopathy is the generic term for a disease of the blood vessels (arteries, veins, and capillaries). [DorlandsDict|one/000005089|angiopathy] The best known and most prevalent angiopathy is the diabetic angiopathy, a complication that may occur in chronic diabetes.

Classification

By caliber

There are two types of angiopathy: macroangiopathy and microangiopathy. In macroangiopathy, fat and blood clots build up in the large blood vessels, stick to the vessel walls, and block the flow of blood. In microangiopathy, the walls of the smaller blood vessels become so thick and weak that they bleed, leak protein, and slow the flow of blood through the body. The decrease of blood flow through stenosis or clot formation impair the flow of oxygen to cells and biological tissues (called ischemia) and lead to their death (necrosis and gangrene, which in turn may require amputation). Thus, tissues which are very sensitive to oxygen levels, such as the retina, develop microangiopathy and may cause blindness (so-called proliferative diabetic retinopathy). Damage to nerve cells may cause peripheral neuropathy, and to kidney cells, diabetic nephropathy (Kimmelstiel-Wilson syndrome).

Macroangiopathy, on the other hand, may cause other complications, such as ischemic heart disease, stroke and peripheral vascular disease which contributes to the diabetic foot ulcers and the risk of amputation.

By condition

It is also possible to classify angiopathy by the associated condition:
* Diabetic angiopathy
*Congophilic angiopathy
