In brief

Venous malformations can cause persistent pain, swelling, and functional limitations.

What is Sclerotherapy?

Sclerotherapy is a specialized medical procedure where a liquid or foam agent (sclerosant) is injected directly into the abnormal veins. This agent causes the vessel walls to collapse and eventually transform into harmless scar tissue, which is naturally absorbed by the body.

The procedure is performed by an Interventional Radiologist using advanced imaging guidance, such as Ultrasound or Fluoroscopy, to ensure maximum precision and safety.

Why Choose Sclerotherapy?

Compared to traditional surgery, Sclerotherapy offers several distinct advantages for patients with vascular anomalies:

  • Minimally Invasive: No surgical incisions are required, meaning no significant scarring.
  • High Precision: Performed under real-time imaging to target only the affected vessels.
  • Reduced Risk: Lower risk of bleeding and complications compared to open surgery.
  • Faster Recovery: Most patients return to their daily activities within a few days.
  • Symptom Relief: Highly effective at reducing the pain caused by internal blood clots (phleboliths) and decreasing localized swelling.

What to Expect During the Procedure

The treatment is typically performed as an outpatient procedure or may require a very short hospital stay.

  • Preparation: The area is cleaned, and a local anesthetic is applied to ensure your comfort.
  • The Injection: Using ultrasound guidance, a fine needle is inserted into the malformation to deliver the sclerosant.
  • Post-Procedure: You may experience mild swelling or bruising at the site for a few days. This is a normal part of the healing process as the malformation begins to shrink.

In many cases, a series of 2-4 treatment sessions may be required to achieve the optimal clinical result, depending on the size and complexity of the malformation.

A Multidisciplinary Approach Every patient is unique

Our team evaluates each case individually to determine if Sclerotherapy is the best primary treatment or if it should be combined with other modern techniques, such as laser therapy or specialized medication.

Frequently asked questions

What is sclerotherapy for vascular malformations and how does it work?

Sclerotherapy is a minimally invasive treatment in which a dedicated solution is injected directly into abnormal blood vessels. The substance causes the affected veins to collapse and shrink, reducing swelling, pain, and improving appearance. The procedure is performed under precise imaging guidance without the need for surgery.

Is sclerotherapy painful?

The procedure is performed under local anesthesia combined with sedation, so there is no significant pain during treatment. Afterward, mild discomfort or a feeling of pressure may occur, but this is usually temporary and can be managed with simple pain relief medications.

How long does the procedure take and what is the recovery time?

The procedure typically lasts between one to two hours. In most cases, patients are discharged the same day and can return to normal activity within a few days. Local swelling may last for one to two weeks.

How many treatments are needed for vascular malformations?

In most cases, more than one treatment is required, especially for larger or deeper malformations. The number of treatments depends on the size, location, and response to therapy.

Is sclerotherapy dangerous?

The treatment is suitable for patients with vascular malformations causing pain, swelling, or aesthetic concerns. Suitability is determined after clinical evaluation and imaging to confirm the type of malformation.

Can sclerotherapy help avoid surgery?

Yes. In many cases, sclerotherapy is an effective and safe alternative to surgery, especially for lesions without clear boundaries or with a higher risk of bleeding.

When will I see results after sclerotherapy?

Results are not immediate. Improvement in swelling and pain is usually seen within a few weeks, with continued improvement over time.

Is the treatment covered by health insurance?

In many cases, the procedure can be performed through health insurance providers or privately with partial reimbursement from private insurance. There is also the option to choose the treating physician in a private setting.

Can sclerotherapy completely cure the condition?

Sclerotherapy does not completely cure the malformation, but it provides excellent symptom control and significantly improves quality of life.
