Keep an affected extremity warm but do not apply direct heat. Keep an affected extremity at or below a horizontal position. Protect an affected extremity from resting on hard surfaces, and do not allow pressure on the affected part. The outcome varies depending on the location of the embolism and the extent that the embolism affects blood supply to the area. Arterial embolism can be serious if not treated promptly.
Arterial emboli can recur even after successful treatment.
