What is Sclerotherapy for Varicose Veins?

Sclerotherapy is a procedure used to treat enlarged, twisted veins that commonly appear on the legs. A special varicose veins solution is injected directly into the affected veins. This swells the lining of the vein, causing it to break and shut the blood flow. There are two ways to perform the procedure:

  1. Foam Sclerotherapy: This involves mixing a sclerosing agent with air or gas to create a foam-like solution. It can cover a larger area within the vein, making it effective for treating larger affected vessels.

  2. Liquid Sclerosing Therapy: It uses a fluid sclerosing agent injected directly into the vein. It is used for smaller varicose or spider veins because the liquid can more easily penetrate and close off the affected vessels.

Who needs Sclerotherapy for Varicose Veins?

Varicose veins sclerotherapy is recommended for individuals who experience discomfort or are dissatisfied with the appearance of their legs. This procedure may be suitable for:

  1. Those with visible, bulging veins

  2. Patients diagnosed with venous insufficiency (poor leg circulation)

  3. Individuals experiencing symptoms such as pain, swelling, or heaviness in the legs

  4. Patients seeking cosmetic improvement

Conditions Treated with Sclerotherapy for Varicose Veins

Sclerotherapy is one of the best treatments for varicose veins as it effectively addresses venous conditions, relieving discomfort. It helps to improve the appearance of the affected area. Common conditions treated include:

  1. Varicose Veins: Enlarged, twisted blood vessels often appear blue or purple on the legs.

  2. Spider Veins: Smaller, web-like veins that can be red, blue, or purple and are commonly found on the legs.

Before and On the Day of Sclerotherapy

Certain preparations are necessary before and on the day of foam sclerotherapy to ensure the procedure's effectiveness and safety. The steps involved are mentioned below.

Sclerotherapy Procedure

Liquid or foam sclerotherapy is a minimally invasive procedure performed without anaesthesia. One session of sclerotherapy takes 30-45 minutes, depending on severity. Below are the steps of the procedure:

  1. Preparation: The skin is cleansed, and the targeted veins are identified.

  2. Injection: A fine needle injects the sclerosing agent into the affected vessels. The sclerosant causes the vein to swell and eventually close off. As the vein closes, blood is rerouted through healthier veins, improving circulation.

  3. Compression: Stockings or bandages are applied to the treated leg to help compress the veins.

After Surgery and Recovery

After your treatment, the doctor may ask you to lie down for 15 minutes to ensure you do not have adverse reactions to the injected substance.

You'll be able to do your usual activities, especially walking. To compress the treated vessels, it's advisable to wear support stockings or compression wraps for three to seven days after treatment. 

The Recovery Process in Hospital 

During the patient’s time in the hospital, various measures will be taken to promote healing and minimise potential complications. 

  1. Observation and monitoring of the treated site by medical staff

  2. Compression therapy to aid in healing

Recovery Process/Expectation After Hospital Discharge 

For the initial 48 hours following your procedure, adhere to the recommendations by the doctor. They can advise the following:

  1. Wearing compression stalkings or bandages for at least two weeks

  2. Do not shave or put lotion on the injected site until it heals

  3. Avoid exposure to the sun for two weeks or use sunscreen with a minimum of 30 SPF

First Follow-Up Appointment

The first follow-up appointment after the sclerotherapy procedure is essential for assessing the progress and ensuring the recovery is on track. During this visit, one may expect the following:

  1. Assessment of treatment outcomes

  2. Discussion of any lingering symptoms or concerns

  3. Guidance on long-term care and maintenance

Benefits of Sclerotherapy

Sclerotherapy is known to be the best treatment for varicose veins as it offers a range of benefits. This procedure assists in effectively improving overall vein health. The key advantages are:

  1. Cosmetic Enhancement: Sclerotherapy diminishes the appearance of varicose veins, restoring smoother, clearer skin.

  2. Minimally Invasive: It requires no anaesthesia and requires no downtime. This allows patients to resume their daily activities shortly after treatment.

  3. Improved Circulation: This method redirects blood flow to healthier veins by closing off damaged veins, improving overall circulation.

Risks and Complications of Sclerotherapy

Sclerotherapy removes affected veins in 75% to 90% of cases. However, it's essential to be aware of potential risks. The major complications include:

  1. Allergic reactions to the sclerosant solution

  2. Hyperpigmentation at the injection site

  3. Formation of blood clots in treated veins

  4. Ulceration or tissue damage

When to Consult a Doctor?

Consulting a doctor promptly can help address issues before they escalate. The instances when it's essential to visit a medical professional are:

  1. Severe pain or discomfort at the injection site

  2. Excessive swelling or inflammation

  3. Persistent skin changes, such as ulceration or discolouration

  4. Any signs of allergic reactions, such as rash or difficulty breathing

Risks of Delaying Sclerotherapy

Varicose veins can worsen over time and negatively impact daily activities and quality of life. Delaying it can also reduce the efficacy of therapies like sclerotherapy. Other risks involved are as follows:

  1. Increased discomfort, swelling, and pain in the affected area

  2. Progression of varicose veins, leading to larger, more pronounced bulges

  3. Higher risk of developing complications such as blood clots or skin ulcers
