BLOOD CLOT BLOCKING AN ARTERY (ARTERIAL THROMBOSIS)

SYMPTOMS

The symptoms of a blood clot blocking an artery (arterial thrombosis) differ based on the exact spot of the blood clot. Some thrombosis symptoms include:

• Mental changes
• Swelling of arm or leg
• Pain in one leg
• Weakness or numbness on a single side of the body
• Chest pain

However, many individuals may have no signs of a blood clot in their artery until it has created additional issues by limiting blood flow to body parts.

DIAGNOSIS

If a person suspects a blood clot blocking an artery (arterial thrombosis) or has risk factors for developing one, they should share their medical history and notify their doctor. A physical examination is performed to assess symptoms, and if a heart attack is suspected, blood testing for troponin may be ordered.

Imaging techniques like electrocardiograms, angiograms, and ultrasounds are used to examine arteries and identify clots. In some cases, invasive treatments like angiograms may be indicated.

TREATMENT

To treat a blood clot blocking an artery (arterial thrombosis), doctors may offer the following treatments:

Surgery

Surgical treatments for arterial thrombosis block heart arteries include carotid endarterectomy and coronary artery bypass, which eliminate fatty deposits and blood vessels. Interventional coronary angioplasty may enlarge the artery without incision.

Blood Thinners

As the first step of therapy for clots, doctors may give thrombolytics, which dissolve rapidly but cause hazardous bleeding. Some patients may need to keep taking these medications in order to reduce their clot risk. Patients who are pregnant or undergoing surgery may not be suitable, and those with atherosclerosis, heart attacks, or stroke may need lifetime treatment.

Behavioral Changes

Others may need behavioral or nutritional changes to minimize plaque in their arteries.
