Superficial thrombophlebitis and deep vein thrombosis
Superficial thrombophlebitis and deep vein thrombosis are different conditions. Superficial thrombophlebitis often causes a tender lump along a vein. Deep vein thrombosis can cause pain and swelling in one leg and needs prompt medical assessment. Examination and duplex ultrasound help distinguish them. Treatment is selected by a doctor, not by an online test.
When blood pools in a varicose vein, a clot can form and the vein wall can become inflamed. Common contributing factors include advanced varicose veins, vein injury, prolonged immobility, dehydration and increased blood clotting tendency. Superficial thrombophlebitis is painful but usually manageable when assessed promptly with ultrasound.
Symptoms
What to pay attention to
Painful cord
A firm, painful cord along the vein that can be felt under the skin.
Redness
The skin over the vein reddens and becomes warm to the touch.
Pain and swelling
The area hurts to the touch and during movement, swelling is possible.
General malaise
Sometimes a slight increase in temperature.
Why can't you delay?
Superficial thrombophlebitis can extend towards the deep veins, increasing the risk of deep vein thrombosis and pulmonary embolism. Seek medical assessment and ultrasound if a painful lump or redness develops along a vein. Do not heat or massage the area yourself.
Treatment
What we do
First, an ultrasound scan assesses the extent of the clot and the condition of the deep veins. The doctor then treats the inflammation and, after the condition stabilises, addresses the affected varicose vein with a minimally invasive technique.
No. Heating, massaging or rubbing the area can be dangerous. Seek medical advice and have an ultrasound scan; a clinician will determine the next steps.
Is this the same as thrombosis?
Superficial thrombophlebitis affects veins beneath the skin, while deep vein thrombosis is a more serious condition involving the deep veins. Ultrasound is needed to distinguish them and assess the risk.
Is it necessary to treat varicose veins after thrombophlebitis?
Yes. If a varicose vein is the underlying cause, the doctor may recommend closing it after the acute condition has stabilised to reduce the risk of recurrence.
