Arm DVT: Causes, Risks & Treatment - A Comprehensive Guide

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.
