Superficial thrombophlebitis can pose grave health risks

Superficial Thrombophlebitis

Superficial thrombophlebitis is an inflammatory-thrombotic condition in which a thrombus forms in a vein near the skin’s surface. In contrast to deep venous thrombosis (DVT), which can be asymptomatic and without phlebitis, most superficial veins that develop thrombosis also develop phlebitis.

Although superficial thrombophlebitis most commonly affects the lower extremities, it has also been reported in the penis and breast (Mondor disease). When intravenous (IV) catheters are used, superficial thrombophlebitis can develop anywhere there are medical interventions, such as in the arm or neck (external jugular vein).

Medical and surgical textbooks pay little attention to thrombosis and thrombophlebitis of the superficial venous system. Thrombophlebitis, on the other hand, is a common occurrence, and although it is usually a benign, self-limiting condition, it can be recurrent and tenaciously persistent, resulting in severe incapacitation.

Thrombophlebitis can spread to the deep venous system when it affects the great saphenous vein (GSV; also known as the higher or long saphenous vein). Chronic deep venous insufficiency (also known as postphlebitic syndrome) results from damage to the deep venous valves, as well as frequent pulmonary embolism (PE) and an increased risk of death.

Causes and sites of development

Superficial thrombophlebitis can develop spontaneously, particularly in the GSV’s lower extremities, or as a result of medical or surgical interventions. Although the cause is often unknown, superficial venous thrombosis is commonly linked to one of the Virchow triad’s components, such as intimal damage, stasis or turbulent flow, or changes in blood constituents.

Each type of superficial thrombophlebitis causes redness and tenderness along the vein’s course, which is also accompanied by swelling. At the site of a varicose vein, bleeding may also occur.

In the small saphenous vein (SSV; also known as the lesser saphenous vein), which empties into the popliteal vein, superficial thrombophlebitis can occur.

If the external jugular vein has been used as an infusion site, superficial thrombophlebitis may develop. Infusion sites or trauma sites are the most common sites for superficial thrombophlebitis of the upper extremities.

Treatment and diagnosis

A clinical diagnosis of superficial thrombophlebitis is when the clinician notices tender and inflamed superficial veins. However, excluding DVT in a clinical setting is difficult; additional testing is often needed to diagnose this condition.

The goal of treatment for superficial thrombophlebitis is to make the patient as comfortable as possible while also preventing the disease from spreading to the deep veins.

Septic thrombophlebitis is a clinical entity characterised by superficial phlebitis with infection, such as phlebitis originating at an IV catheter site. It requires diagnostic and therapeutic approaches that are distinct from sterile phlebitis.
