从下到上依次排列着轻、中、重三种不同程度的动脉粥样硬化。下面轻度粥样硬化仅见散在脂斑。中间的大动脉显示更多、更大的斑块。上面最重的粥样硬化动脉显示在斑块上有大量溃疡形成。
These three aortas demonstrate mild, moderate, and severe atherosclerosis from bottom to top. At the bottom, the mild atherosclerosis shows only scattered lipid plaques. The aorta in the middle shows many more larger plaques. The severe atherosclerosis in the aorta at the top shows extensive ulceration in the plaques.
