Sclerotherapy in Singapore
Minimally Invasive Treatment for Selected Vascular Malformations
Sclerotherapy is a minimally invasive, image-guided treatment used for selected peripheral vascular malformations, particularly low-flow venous and lymphatic malformations.
During the procedure, a specialised sclerosing medication is injected directly into the vascular malformation. The medication acts on the abnormal vascular spaces, causing them to shrink and gradually close.
Depending on the size, location and type of vascular malformation, treatment may require more than one session.
At the Supreme Vascular and Interventional Clinic, treatment is carefully planned according to the characteristics of the malformation, its blood-flow pattern and the surrounding anatomy.
Care is led by Dr. Manish Taneja, providing specialist vascular and interventional expertise with a continuum of care under one roof.

What Is Sclerotherapy for Vascular Malformations?
Sclerotherapy is a treatment that uses a sclerosant medication to target abnormal vascular spaces.
Unlike conventional sclerotherapy used for spider or varicose veins, sclerotherapy for vascular malformations is specifically designed to treat abnormal vascular channels or spaces within the malformation. The sclerosant is injected directly into the malformation, causing the abnormal spaces to become inflamed and gradually shrink.
The goal is to reduce the size and activity of the malformation while improving associated symptoms.
What Are Peripheral Vascular Malformations?
Vascular malformations are abnormalities in the development of blood vessels. They can occur in different parts of the body and may involve veins, lymphatic vessels, arteries or combinations of these.
Peripheral vascular malformations can occur in areas such as:
- Limbs
- Soft tissues
- Head and neck
- Trunk
- Other areas outside the central nervous system
Their symptoms and appearance can vary depending on the type and location.
Some may cause:
- Swelling
- Pain or discomfort
- Changes in the appearance of the skin or underlying tissue
- A feeling of fullness
- Bleeding in selected cases
- Functional problems depending on their location
Which Vascular Malformations Can Be Treated With Sclerotherapy?
Sclerotherapy is particularly useful for selected low-flow vascular malformations.
Venous Malformations
Venous malformations consist of abnormal venous spaces and are among the vascular malformations most commonly considered for sclerotherapy.
Treatment can reduce the size of the abnormal venous spaces and may help improve associated swelling or discomfort.
Lymphatic Malformations
Selected lymphatic malformations may also respond to sclerotherapy.
The treatment approach depends on the characteristics and location of the malformation.
Mixed Vascular Malformations
Some malformations contain more than one vascular component.
These require careful assessment to determine which treatment approach is most appropriate.
High-Flow Malformations
High-flow malformations, such as many arteriovenous malformations, are generally approached differently.
Embolisation may be more appropriate for selected high-flow malformations.
Sclerotherapy vs Embolisation
These are both minimally invasive treatments, but they are used for different vascular conditions and flow characteristics. The choice between sclerotherapy, embolisation or another treatment depends on the specific vascular anatomy.
| Sclerotherapy | Embolisation |
|---|---|
| Commonly used for selected low-flow malformations | Commonly used for selected high-flow vascular abnormalities |
| Sclerosant is injected directly into the malformation | Embolic material is delivered through a catheter into targeted blood vessels |
| Particularly relevant to venous and lymphatic malformations | Particularly relevant to selected AVMs and other abnormal vascular connections |
| May require multiple treatment sessions | May also be performed in staged sessions |
Potential Benefits of Sclerotherapy
A Targeted Minimally Invasive Treatment
For appropriately selected patients, sclerotherapy for peripheral vascular malformations may offer several potential benefits.
Minimally Invasive
Treatment is performed through a small needle, allowing the targeted vascular malformation to be treated without conventional open surgery.
Directly Targets the Malformation
The sclerosing medication is delivered directly into the abnormal vascular spaces to help reduce their size and blood flow.
Image-Guided Treatment
Ultrasound and other imaging techniques can be used to help identify and accurately target the vascular malformation during treatment.
Suitable for Selected Low-Flow Malformations
Sclerotherapy can be particularly useful for selected venous and lymphatic vascular malformations, depending on their type, size and blood-flow characteristics.
Can Be Performed in Stages
Larger or more complex vascular malformations can be treated over multiple sessions when appropriate, allowing the treatment plan to be adapted according to the response.
May Help Reduce Symptoms
By reducing the abnormal vascular spaces, treatment may help improve symptoms such as swelling, discomfort, pain or functional problems associated with the malformation.
Individualised Treatment
The choice of sclerosant, treatment approach and number of sessions can be tailored according to the type, location, size and characteristics of each vascular malformation.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Sclerotherapy for vascular malformations is generally well tolerated, but potential side effects and complications can occur.
These may include:
- Temporary swelling
- Bruising
- Pain or tenderness
- Inflammation around the treated area
- Temporary skin changes
- Localised irritationRecurrence or persistence of the malformation
- The possibility of requiring additional treatment
The risks depend on the location, size and type of vascular malformation and the treatment used.
Your specialist will discuss the specific considerations relevant to your procedure.
Recovery After Foam Sclerotherapy
What Can You Expect After Treatment?
Temporary swelling, discomfort or bruising can occur following treatment. The recovery period varies depending on the location and size of the vascular malformation and the extent of treatment. The injection process typically takes 30 to 60 minutes, though complex or multi-vessel malformations can take up to 1 to 2 hours.
Most peripheral and low-risk head/neck treatments are performed on an outpatient basis and patients can go home the same day. Patients can resume light daily activities and work within 48 hours depending on comfort.
You may be advised to:
- Rest initially
- Keep the treated area protected
- Take prescribed medication if required
- Follow activity restrictions where appropriate
- Monitor the treated area
- Attend scheduled follow-up appointments
Your specialist will provide personalised aftercare instructions.

Frequently Asked Questions About Sclerotherapy
What is sclerotherapy for vascular malformations?
It is a minimally invasive treatment in which a sclerosing medication is injected directly into selected abnormal vascular spaces to reduce their size and blood flow.
What vascular malformations can sclerotherapy treat?
It is commonly considered for selected low-flow venous and lymphatic malformations.
Is sclerotherapy the same as embolisation?
No. Sclerotherapy involves direct injection of a sclerosant into the malformation, while embolisation generally uses a catheter to deliver embolic material into targeted blood vessels.
Can sclerotherapy treat an AVM?
Many AVMs are high-flow malformations and are generally approached differently from low-flow venous malformations. Selected AVMs may be treated with embolisation depending on their vascular anatomy.
Will I need more than one treatment?
Larger or complex vascular malformations may require staged treatment.
Is sclerotherapy minimally invasive?
Yes. It is performed using image-guided injection rather than conventional open surgery.
Will the vascular malformation disappear completely?
The response varies depending on the type, size and location of the malformation. The goal may be to reduce its size, blood flow and symptoms rather than necessarily eliminate every abnormal vessel.
