Arterial embolism Health Article

Expectations (prognosis)

How well a patient does depends on the location of the clot and how much the clot has blocked blood flow. Arterial embolism can be serious if not treated promptly.

The affected area can be permanently damaged. Up to approximately 25% of cases require amputation.

Arterial emboli can come back (recur) even after successful treatment.

Complications

• Acute MI
• Infection in the affected tissue
• Septic shock
• Stroke (CVA)
• Temporary or permanent decrease or loss of other organ functions
• Temporary or permanent kidney failure
• Tissue death (necrosis) and gangrene
• Transient ischemic attack (TIA

Calling your health care provider

Go to the emergency room or call the local emergency number (such as 911) if you have symptoms of arterial embolism.

Prevention

Prevention begins with identifying the source of the blood clot. If your health care provider determines you have a high risk for blood clots, you may be prescribed blood thinners (such as warfarin or Coumadin) to prevent them from forming. Antiplatelet drugs may also be needed.

The risk for both atherosclerosis and clot formation increases in persons who:

• Are inactive and do little exercise
• Are overweight
• Are under stress
• Smoke

Taking steps to reduce hardening of the arteries (atherosclerosis) may reduce your risk of an arterial embolus forming from a piece of plaque.
