An atheroma, or atheromatous plaque, is an abnormal accumulation of material in the inner layer of an arterial wall.[1][2]
The material consists of mostly macrophage cells,[3][4] or debris, containing lipids, calcium and a variable amount of fibrous connective tissue. The accumulated material forms a swelling in the artery wall, which may intrude into the lumen of the artery, narrowing it and restricting blood flow. Atheroma is the pathological basis for the disease entity atherosclerosis, a subtype of arteriosclerosis.[5]
