Cholesterol embolism
Cholesterol Embolism
Cholesterol embolism (pronounced kuh-LES-ter-ol em-BOWL-izm), also known as atheroembolic disease, is a medical condition where cholesterol crystals become lodged in small blood vessels, blocking blood flow.
Etymology
The term "cholesterol embolism" is derived from three words. "Cholesterol" comes from the Greek words chole (bile) and stereos (solid), referring to the waxy substance found in the body's cells. "Embolism" is derived from the Greek embolos (stopper or piston), referring to the blockage of a blood vessel.
Definition
Cholesterol embolism occurs when cholesterol crystals break off from a larger atherosclerotic plaque in the body's larger arteries. These crystals then travel through the bloodstream and can block smaller blood vessels, leading to tissue damage and organ dysfunction. This condition can affect various organs, including the kidneys, skin, brain, and eyes.
Symptoms
Symptoms of cholesterol embolism can vary depending on the organ affected. Common symptoms include:
- Skin discoloration or lesions
- Kidney dysfunction or failure
- Stroke-like symptoms such as weakness or numbness
- Vision changes or loss
- Chest pain
Diagnosis
Diagnosis of cholesterol embolism often involves a combination of physical examination, patient history, and diagnostic tests such as blood tests, imaging studies, and sometimes a biopsy of affected tissue.
Treatment
Treatment for cholesterol embolism focuses on managing symptoms and preventing further emboli. This may include medications to control cholesterol levels, blood pressure, and inflammation, as well as procedures to remove or bypass the source of the emboli.
