Peripheral Arterial Disease

Gross figure showing a dilated and thickened pulmonary artery with yellowish atherosclerotic plaques. The lung parenchyma has a brownish-orange tinge from large collections of hemosiderin-laden macrophages indicating chronic alveolar hemorrhage.

<bold>Figure 34.11 A.</bold> This patient has both atherosclerotic ostial stenosis and fibromuscular dysplasia. The typical appearance of fibromuscular dysplasia <italic>(arrow)</bold> is a corrugation of the vessel. This is diagnostic of fibromuscular dysplasia, but not of renovascular hypertension. <bold>B.</bold> The corrugated appearance of the vessel does not change after balloon angioplasty; however, the ostial lesion has been successfully stented. Stenting of the fibromuscular disease is reserved for pe...

<bold>FIGURE 10-15. Complicated lesions of atherosclerosis.</bold> The luminal surface of the abdominal aorta and the common iliac arteries shows numerous fibrous plaques and raised, ulcerated lesions containing friable, atheromatous debris. The distal portion of the aorta displays a small aneurysmal dilation.
