Arterial microemboli and fibromuscular dysplasia of the external iliac arteries.

A patient who developed acute focal ischemic lesions confined to several toes on the feet is described. The ischemic lesion were typical to those seen in digital arterial microemboli. The source of the microemboli was apparently external iliac artery fibromuscular dysplasia. These lesions were subsequently resected and no subsequent lower extremity embolic events have appeared.
