In a patient with peripheral vascular disease, the principal source of distal emboli is the:
Aorta.
+Femoral artery.
+Heart.
+Iliac artery.
+Popliteal artery.
An embolus is the most common cause of an acute arterial occlusion in the limb and originates from the heart in 80–90% of cases of embolism. The two primary causes of mural thrombus within the heart are atrial fibrillation and recent myocardial infarction.
