The medical procedure foam sclerotherapy is used to treat varicose veins and spider veins. This minimally invasive procedure involves injecting a sclerosant solution directly into the afflicted veins. The sclerosant irritates the veins’ interior lining, causing the veins to collapse and eventually disappear.

How Does Sclerotherapy Work?

Here is a comprehensive description of how sclerotherapy works:
  1. Preparing for the operation: The patient is positioned supine, and the medical professional cleanses the epidermis around the targeted veins. The provider may use a magnifying device or a special light to see the vessels more clearly.
  2. Injection of the sclerosant solution: The healthcare provider injects the sclerosant solution directly into the targeted vessels using a fine needle. The solution causes the inner membrane of the veins to become inflamed and adhere together by irritating them.
  3. Vein closure and absorption: The injection of a sclerosant solution causes the vein walls to collapse and seal shut. This closure stops the passage of blood through the affected veins. Over time, the body absorbs the closed veins naturally, and they progressively disappear.
  4. Compression and healing: Following the injection, the healthcare provider may apply compression to the affected area in order to promote healing. Compression can be obtained through the use of compression hosiery or compression bandages. Compression helps maintain the integrity of the vessels, reduces swelling, and promotes healing.
  5. In many instances, multiple sclerotherapy sessions are necessary to attain the intended results. The number of sessions required is contingent upon the extent of the vessels being treated and the patient’s response to the treatment. Typically, sessions are separated by a few weeks to enable the body to absorb the treated veins and the healthcare provider to evaluate the progress.
  6. The treated veins typically fade progressively over the course of several weeks to months. Common injection site side effects include bruising, transient discoloration, and minor discomfort. The majority of individuals can resume normal activities promptly or within a day of the procedure.

How Long After Sclerotherapy Do Veins Disappear?

The time it takes for veins to disappear after sclerotherapy can differ from person to person. Typically, it takes weeks to months for treated veins to diminish and become less noticeable.

How Many Sclerotherapy Treatments Are Required?

The number of sclerotherapy treatments required depends on the patient and the severity of the vein disorder being addressed. Size, quantity, and location of the vessels, as well as the individual’s response to the treatment, can all impact the number of treatments required.

Sclerotherapy Before And After


Sclerotherapy is generally well tolerated, with minimal distress experienced by the majority of patients. However, discomfort tolerance can vary from person to person, as can the sensation experienced during sclerotherapy.
The timing and intensity of exercise after sclerotherapy may vary depending on individual factors and your healthcare provider’s specific instructions. While light physical activity is typically encouraged after sclerotherapy, it is essential to observe your doctor’s instructions for a safe and speedy recovery.
Despite the fact that sclerotherapy is generally a safe and well-tolerated procedure, it, like all medical interventions, entails the risk of side effects. The majority of adverse effects are mild and transient, resolving without long-term complications. However, it is essential to be aware of possible adverse effects. Sclerotherapy may cause the following adverse effects: temporary discomfort, bruising, discoloration of the skin, small blood clots, allergic reactions, and skin ulceration.
Following sclerotherapy, it is essential to adhere to your healthcare provider’s post-treatment instructions to ensure proper healing and maximise results. The following are some general recommendations regarding what to avoid after sclerotherapy: strenuous exercise, protracted sitting or standing, hot baths, hot tubes, and saunas, excessive sun exposure, tight clothing, and restrictive garments, among others.
