What Are the Causes of Arm Dvt?

Deep vein thrombosis (DVT) of the arm has many causes. Early intervention and treatment is key to preventing the development of more dangerous conditions.

Definition of DVT

• Deep vein thrombosis is a potentially life-threatening condition in which blood clots form in the deep veins of your arms and legs.

Dangers

• If a clot in your arm or leg breaks free, it may travel to your heart and lungs, resulting in a pulmonary embolism (PE). Often silent killers, pulmonary embolisms may cause stroke, heart attack or death.

Symptoms

• Symptoms of DVT include swelling to the area, pain, cramping and tenderness.

Causes

• According to Vascular Web, inserting a catheter in the arm may cause DVT. Catheters may impede venous blood flow and irritate the vein wall. Another cause is having a pacemaker or implantable cardioverter defibrillator. One rare type of DVT is due to repetitive arm motions. It is usually seen in athletes.

Treatment

• Heparin and other anticoagulants are the primary treatment for DVT. These medicines dissolve clots and prevent new ones from forming.

Warning

• If you have symptoms including unexplained swelling, redness or tenderness to an extremity, see your health care provider immediately. While superficial thrombophlebitis is not dangerous, DVT is life-threatening, but easily treated.
