ЭТАП ИНИЦИАЦИИ АТЕРОСКЛЕРОЗА

The pale yellow lipid streaks in the aorta are the earliest lesion of atherosclerosis.

At higher magnification, many foam cells (macrophages full of lipid material) and a cholesterol cleft are seen in this atheromatous plaque.

ЭТАП ПРОГРЕССИРОВАНИЯ АТЕРОСКЛЕРОЗА

Microscopically, the aortic atheromatous plaque is thicker than the remaining media at the right. The plaque contains amorphous pink material with slit-like "cholesterol clefts" of lipid material. There is overlying recent hemorrhage at the left. Thrombus may form on top of such a plaque.

This is a high magnification of the aortic atheroma with foam cells and cholesterol clefts.
