Cholesterol Embolization Syndrome

Cholesterol embolization syndrome occurs when small fragments derived from cholesterol plaques in the arteries break off and block smaller blood vessels, affecting circulation in different areas of the body.

Common manifestations: depending on the organs affected, there may be changes in the skin of the toes or feet, alterations in kidney function, or discomfort in other regions. The manifestations depend on the vessels involved.

Common causes: it is associated with the presence of plaques in the arteries, and is sometimes related to certain vascular procedures or to previously impaired circulation.

Which specialist assesses it? The nephrologist takes part when there is kidney involvement, along with the internist and the vascular specialist depending on the presentation. In the case of signs of impaired circulation or kidney changes, the recommended course is to seek a professional assessment to guide the workup.
