Causes, Symptoms, and Treatment of Superficial Vein Thrombosis
Superficial vein thrombosis (SVT) when a blood clot forms in the veins just under the skin. This condition can develop suddenly due to trauma, prolonged immobility, or underlying medical factors that increase the risk of clotting.
Symptoms may include pain, swelling, redness, and warmth along the vein. In some cases, a firm cord-like vein may be felt under the skin. Though SVT is usually less dangerous than deep vein thrombosis (DVT), complications can occur if a clot spreads or breaks free.
Diagnosis is made with a physical exam and sometimes imaging. Treatment may include anti-inflammatory medications, anticoagulants (blood thinners), and compression therapy to reduce swelling. In rare cases, surgery may be required to remove the clot or repair damaged veins.
With prompt care, most people recover fully from SVT in the arm and can prevent future complications.
