Atheroembolic renal disease (AERD) is an inflammatory reaction in the small blood vessels of the kidneys.
Renal disease - atheroembolic; Cholesterol embolization syndrome; Atheroemboli - renal; Atherosclerotic disease - renal
Causes, incidence, and risk factors
AERD is linked to
In AERD, cholesterol crystals break off from the plaque lining the arteries. These crystals move into the blood stream. Once in circulation, the crystals get stuck in tiny blood vessels called arterioles. There, they cause intense swelling and pain that can harm the kidney or other parts of the body
The result is organ damage due to decreased blood supply. The kidneys are involved about half the tiome. Other body parts that may be involved include the skin, eyes, muscles and bones, brain and nerves, and organs in the abdomen. Acute kidney failure is possible if the reaction is severe.
Atherosclerosis of the aorta is the most common cause of AERD. The cholesterol crystals may also break off during
In some cases, AERD may occur without a known cause.
The risk factors for AERD are the same as risk factors for atherosclerosis.
