Introduction

Thrombophlebitis is a condition that occurs due to the inflammation of a vein, often in connection with the formation of a blood clot, and most commonly affects the legs. This causes swelling and pain along the affected vein site and can lead to further complications such as chronic venous insufficiency if it isn't managed.¹ Compression therapy is often used whilst treating thrombophlebitis. It reduces swelling and improves blood circulation. Compression stockings are one of the various compression methods that are used widely due to their effectiveness in promoting venous return. Compression stockings apply pressure to the leg, with the highest amount of compression being towards the ankle. This helps reduce venous states and prevents blood pooling.² The use of compression therapy in the management plan enables patients to experience relief and reduce the risk of further complications; it is widely recognised as a valuable non-invasive treatment option for thrombophlebitis.

Understanding thrombophlebitis

Thrombophlebitis is a disorder in which a vein becomes inflamed as a result of a blood clot, causing pain, swelling, and soreness in the affected area. The condition is classified into two types: superficial thrombophlebitis and deep vein thrombosis (DVT). Superficial thrombophlebitis, which is usually less serious, affects the veins just under the skin's surface.³ DVT occurs in deeper veins, often in the legs, and leads to severe complications, including pulmonary embolism if a clot dislodges and travels to the lungs.

Multiple factors can contribute to the development of this condition, such as injury to the vein (from trauma or surgery), lengthened immobility (like long flights and bed rest), smoking, pregnancy, obesity, and other medical conditions that promote blood clotting tendencies.³ Symptoms often include swelling, redness, tenderness, and tightening along the vein; however, with DVT, patients may experience these symptoms with more severity and pain.

If thrombophlebitis is left untreated, further complications are likely to occur, such as post-thrombotic syndrome and chronic venous insufficiency. Early diagnosis is important for the prevention and appropriate management of these complications.

Compression therapy

Compression therapy is a very commonly used method that involves applying controlled pressure to limbs, typically the legs, to reduce swelling, improve blood circulation, and reduce discomfort associated with venous disorders. The treatment usually involves the use of compression stockings, mechanical devices, or bandages.

The mechanism by which compression therapy works in thrombophlebitis is by enhancing venous return. In this method, the pressure is applied to improve blood flow by squeezing the veins and forcing the blood to flow more effectively towards the heart. A graduated pressure, where higher pressure is applied towards the ankles and is decreased up the leg. This method prevents further clot formation and promotes blood flow.²

Compression therapy also promotes lymphatic drainage and helps reduce fluid accumulation in tissues, which ultimately reduces swelling. The prevention of blood pooling in the veins and promoting circulation using compression therapy helps lower the risk of further complications associated with thrombophlebitis. The regular use of compression stockings in combination with other medical treatments can massively enhance the recovery process.

Role of compression stockings in thrombophlebitis

Compression stockings are essential in the treatment of thrombophlebitis, as stockings act by increasing blood circulation, decreasing swelling, and averting complications. With the greatest compression at the ankle and a progressive decrease towards the thigh, they deliver graduated pressure to the legs. By pushing blood upward, this design improves venous return to the heart, lessens venous stasis, and offsets the effects of gravity. By doing this, they reduce inflammation, tackle clots, and provide symptomatic treatment.

The numerous categories of compression stockings are determined by the level of compression they offer. Graduated compression stockings, which provide varying pressure levels in millimetres of mercury (mmHg), are the most widely used type. These are usually categorised as four types: mild (8–15 mmHg) for mild swelling or fatigue, moderate (15–20 mmHg) for mild varicose veins or travel-related swelling, firm (20–30 mmHg) for more significant venous disorders, and extra firm (30–40 mmHg or higher) for severe venous insufficiency and post-thrombotic syndrome.⁴ The different levels are recommended by doctors based on how severe the condition is.

Proper guidelines must be followed to ensure the best outcomes of the use of compression stockings. They should be worn in the morning before swelling develops and removed before bed. It should have a snug fit, as this could restrict circulation if too tight. Patients should follow the physician's guidance regarding the proper compression level and usage length. Their elasticity and efficacy are also guaranteed by regular maintenance, which includes cleaning and replacing them every three to six months.⁵ Compression stockings are a straightforward yet effective treatment for thrombophlebitis to avoid long-term consequences when used properly.

Clinical evidence and effectiveness

Several clinical studies support the use of compression stockings in the treatment of thrombophlebitis. This clinical evidence shows the positive effects in reducing symptoms and improving health. Research has shown that graduated compression stockings can significantly reduce pain, swelling, and the risk of further complications when used with other standard treatments.⁵ For example, a study published in 'The Lancet' indicates that compression therapy, especially in superficial thrombophlebitis, helps improve symptom relief and promotes faster resolution of inflammation compared to no compression.⁶

Stockings are used with anticoagulant treatments rather than alone. Anticoagulants are critical in preventing clot extension and pulmonary embolism in deep vein thrombosis, although they are associated with a risk of bleeding and require continuous monitoring. In contrast, compression stockings are safe and non-invasive, making them suitable for long-term use, particularly in patients who are unable to take anticoagulants. Other pain relief lifestyle modifications, such as increased movement and elevating the legs, are also beneficial. Therefore, the combination of these changes with compression therapy can improve overall treatment efficiency.⁷

Nevertheless, there are a few restrictions and contraindications to consider. Compression stockings may not be appropriate for patients with peripheral arterial disease, skin infections, or open wounds, as they may worsen circulation and cause discomfort.

Compression stockings may not be suitable for individuals with severe peripheral arterial disease, skin infections, or open wounds, as they may worsen circulation or cause discomfort. Furthermore, wrong sizing or improper application can cause skin irritation or poor compliance. Despite these factors, compression stockings are nevertheless a clinically validated and successful treatment for thrombophlebitis when used correctly and under medical advice.¹

Practical considerations and patient compliance

Proper use of compression stockings in thrombophlebitis management is important and requires careful attention to size and pressure level, typically ranging from 15–20 mmHg for mild cases to 20–30 mmHg or higher for more intense symptoms. Accurate leg measurements, ideally taken in the morning, can ensure a good fit that provides effective support without causing discomfort.⁴

Compression stockings are expected to be worn daily, starting in the morning before the swelling develops, and removed at night. The elasticity of the stockings needs to be maintained by regular washing and by replacing them every three to six months. It is also essential to address concerns from patients, such as tightness and difficulty. It is possible to promote consistent usage and enhance treatment results by informing patients about the advantages, offering advice for simpler use (such as donning aids), and providing continuing support.¹

Summary

Compression therapy, specifically through the use of compression stockings, plays a vital role in the management of thrombophlebitis by improving venous return, reducing swelling, and relieving symptoms. Compression stockings are a safe, non-invasive, and efficient addition to other treatments like anticoagulants and lifestyle changes when they are fitted correctly and worn regularly. Incorporating compression therapy into routine treatment regimens promotes quicker symptom relief and helps avoid chronic venous insufficiency and other long-term issues. Future studies should concentrate on maximising compression levels, enhancing patient comfort and adherence, and investigating the long-term effects of compression therapy in various patient populations as our knowledge of thrombophlebitis continues to evolve. Its usefulness and usability in routine clinical practice will be further improved by ongoing research and development.
