ath·er·o·ma

(ath'er-ō'mă),
The lipid deposits in the intima of arteries, producing a yellow swelling on the endothelial surface; a characteristic of atherosclerosis.

ATHEROMA

Angiographic intervention Trial using HMG CoA reductase inhibitor to Evaluate Retardation of Obstructive Multiple Atheroma. A trial comparing changes in coronary atheromas with pravastatin vs diet in patients with CHD.
Conclusion Pravastatin 10–20 mg/day for 3 years improves hyperlipidaemia, then suppresses progression and induces regression of focal coronary atherosclerosis in Japanese coronary artery disease patients with raised serum cholesterol.

ath·er·o·ma

(ath'ĕr-ō'mă)
The lipid deposits in the intima of arteries, producing a yellow swelling on the endothelial surface; a characteristic of atherosclerosis.
[G. athērē, gruel, + -ōma, tumor]

atheroma

The material containing CHOLESTEROL, degenerate muscle cells, blood clot, blood PLATELETS and fibrous tissue, which forms on the inner surface of arteries in the disease of ATHEROSCLEROSIS and which promotes THROMBOSIS and obstruction to the blood flow. From the Greek athara , gruel or porridge, and oma , a lump.

atheroma

degeneration of the inner lining of an artery, caused by the formation of fatty plaques and scar tissue.

atheroma 

Fatty deposits which lead to the formation of plaques in the blood vessels. See arteriosclerosis; Hollen-horst's plaques.

The Katz classification for grading aortic atheromas is as follows: Grade 1, normal-appearing intima of the aorta; Grade 2, extensive intimal thickening; Grade 3, sessile atheroma protruding <5 mm into the aorta; Grade 4, atheroma protruding >5 mm; and Grade 5, mobile atheroma [15].
The prevalence of calcified carotid artery atheromas on the panoramic radiographs of patients with type 2 diabetes mellitus.
DISCUSSION: Atherosclerosis is a chronic inflammatory disease of multifactorial origin characterized by artery walls thickening or elasticity loss, many times associated with presence of atheromas. Atheromas are plaques that may calcify caused by accumulation of lipids or fibrous tissue in blood vessels.
The total atheroma volume (TAV), a secondary endpoint, decreased compared with baseline by 5.62 [mm.sup.3] in the diabetic group and by 7.29 [mm.sup.3] in the nondiabetic group, both of which also were significant changes, he said at the annual meeting of the American College of Cardiology Data came from the SATURN (Study of Coronary Atheroma by Intravascular Ultrasound: Effect of Rosuvastatin Versus Atorvastatin) trial, which compared intensive therapy with one of the two statin drugs in patients who underwent serial intravascular ultrasonography to assess disease regression.
Plaque regression was demonstrated by a reduction in the mean percent atheroma volume from 39.6% at baseline to 38.6% at end point (P<.001); 64% of patients exhibited plaque regression on IVUS.
Oskar Klotz (12) was quick to point out that, although more specific, Marchand's designation was not applicable to all arteriosclerotic lesions, like those described by Monckeberg, in which no true atheroma is present.
