Cryoablation in Singapore
Minimally Invasive Image-Guided Treatment Using Controlled Freezing
Cryoablation is a minimally invasive image-guided treatment that uses controlled freezing and thawing to destroy targeted abnormal tissue. Unlike radiofrequency ablation and microwave ablation, which use heat, cryoablation uses extremely cold temperatures to create a controlled area of frozen tissue around the treatment probe. The treatment zone can be monitored using imaging to help the specialist target the affected tissue while limiting treatment of surrounding structures where possible.
Cryoablation may be used for selected tumours as part of interventional oncology care and, in appropriately selected patients, for certain peripheral vascular malformations such as venous malformations and fibro-adipose vascular anomaly (FAVA).
At the Supreme Vascular and Interventional Clinic, cryoablation is considered as part of a broader minimally invasive treatment approach. Dr. Manish Taneja assesses each patient individually to determine whether cryoablation or another treatment option is appropriate based on the condition, imaging findings, anatomy and treatment goals.
With expertise spanning the brain and body, the Supreme Vascular and Interventional Clinic provides specialist-led vascular and image-guided treatment with a continuum of care under one roof.

What Is Cryoablation?
Cryoablation is a minimally invasive treatment that uses extreme cold to destroy targeted tissue.
During treatment, a specialised cryoprobe is inserted through the skin and guided towards the target using medical imaging. The probe creates a controlled zone of freezing around the treatment area.
The tissue is then allowed to thaw, and additional freeze-thaw cycles may be performed depending on the treatment plan. This process can cause targeted cellular damage while allowing the specialist to monitor the treatment area using imaging.
Cryoablation can be used in different clinical settings, including selected tumour treatments and selected peripheral vascular malformations.
How Does Cryoablation Work?
Controlled Freezing and Thawing of Targeted Tissue
Before treatment, imaging is used to assess the target area and its relationship to surrounding structures.
During the procedure, one or more cryoprobes are carefully positioned within or adjacent to the targeted tissue.
Extremely cold temperatures are then delivered through the probe, creating an area of frozen tissue. This may appear as an "ice ball" on certain forms of imaging, allowing the specialist to monitor the treatment zone.
The tissue is subsequently allowed to thaw, and additional freeze-thaw cycles may be performed according to the treatment plan.
Once the planned treatment has been completed, the probes are removed.
Cryoablation for Selected Tumours
Minimally Invasive Tumour Ablation
Cryoablation can be used to treat selected tumours by freezing and destroying targeted tumour tissue.
It may be considered for certain solid tumours where a local, image-guided treatment is appropriate. Depending on the tumour and individual circumstances, cryoablation may be used as an alternative to surgery, when surgery is not appropriate, or as part of a broader cancer treatment plan.
Selected applications may include tumours involving:
- The kidney
- The liver
- The lung
- Bone and soft tissue
- Other selected tumour sites
The suitability of cryoablation depends on the tumour's type, size, location and relationship to surrounding structures.
Cryoablation does not replace all forms of cancer treatment. Some patients may require surgery, radiotherapy, systemic therapy or a combination of treatments.
Cryoablation for Peripheral Vascular Malformations
Image-Guided Treatment for Selected Symptomatic Vascular Malformations
Cryoablation may also be considered for selected peripheral vascular malformations, particularly certain venous malformations and fibro-adipose vascular anomaly (FAVA).
These conditions can sometimes cause persistent pain, swelling, discomfort or functional limitations. Image-guided percutaneous cryoablation can be used to target selected abnormal tissue and may help reduce symptoms in appropriately selected patients.
Cryoablation may be considered when:
- The vascular malformation causes significant symptoms
- The lesion has a suitable location and anatomy
- A targeted image-guided treatment is appropriate
- Previous treatment such as sclerotherapy has not provided sufficient relief
- A minimally invasive approach is preferred or appropriate
Not every vascular malformation is suitable for cryoablation. Careful clinical assessment and imaging are required to determine the type, extent and characteristics of the malformation before treatment.
Cryoablation for Venous Malformations
Venous malformations are abnormal collections of veins that can cause pain, swelling, discomfort or other symptoms.
Sclerotherapy is commonly used for selected venous malformations. However, cryoablation may be considered in specific circumstances, particularly when a lesion has a suitable focal target or when symptoms persist despite other treatments.
Treatment is performed using image guidance to position the cryoprobe within or close to the targeted abnormal tissue. The treatment approach depends on the size, depth, location and structure of the venous malformation.
Cryoablation for Fibro-Adipose Vascular Anomaly (FAVA)
Fibro-adipose vascular anomaly, or FAVA, is a type of vascular anomaly that can cause persistent pain and functional problems.
For selected symptomatic FAVA lesions, image-guided percutaneous cryoablation may be considered to target the affected tissue and reduce symptoms. Published studies have reported improvement in pain and associated symptoms following treatment in appropriately selected patients.
Treatment planning requires detailed imaging to understand the lesion and its relationship to nearby muscles, nerves, blood vessels and other structures.
Cryoablation vs Other Ablation Treatments
Cryoablation is one of several image-guided ablation techniques available for selected conditions.
| Treatment | How It Works | General Approach |
|---|---|---|
| Cryoablation | Uses controlled freezing and thawing to destroy targeted tissue | Freezing-based |
| Radiofrequency Ablation (RFA) | Uses radiofrequency energy to generate heat | Thermal |
| Microwave Ablation | Uses microwave energy to generate heat | Thermal |
| Irreversible Electroporation (IRE) | Uses electrical pulses to create permanent pores in cell membranes | Non-thermal |
The most appropriate technique depends on the condition being treated, the size and location of the target, surrounding anatomy and the patient's individual circumstances.
Cryoablation vs Sclerotherapy for Vascular Malformations
Cryoablation and sclerotherapy are different minimally invasive treatments and are used for different treatment purposes.
| Cryoablation | Sclerotherapy |
|---|---|
| Uses controlled freezing to treat targeted tissue | Uses a sclerosing agent to close abnormal vessels |
| Uses image-guided cryoprobes | Usually involves image-guided injection where appropriate |
| May be considered for selected venous malformations and FAVA | Commonly used for selected low-flow vascular malformations |
| Can be particularly useful for selected symptomatic lesions | Treatment approach depends on the type and anatomy of the malformation |
| May be used when other treatment approaches have not provided sufficient relief | May require multiple treatment sessions |
The appropriate treatment depends on the type of vascular malformation, its anatomy, symptoms and previous treatment.
Potential Benefits of Cryoablation
Minimally Invasive Treatment
Cryoablation is performed through small percutaneous access points rather than requiring conventional open surgery.
Targeted Treatment
The cryoprobe can be positioned directly within or close to the targeted tissue under image guidance.
Controlled Treatment Zone
Imaging can help the specialist monitor the area being treated and assess its relationship with surrounding structures.
Can Be Used for Different Conditions
Cryoablation can be considered for selected tumours as well as certain peripheral vascular malformations.
May Reduce Symptoms
For selected symptomatic vascular malformations, cryoablation may help reduce pain and other associated symptoms.
May Be Part of a Broader Treatment Plan
Cryoablation can sometimes be combined with or used alongside other treatments depending on the condition and individual treatment goals.
Risks and Considerations
Cryoablation is a specialised image-guided procedure and, like any medical treatment, has potential risks.
The risks depend on the area being treated and may include:
- Temporary pain or discomfort
- Bleeding or bruising at the treatment site
- Swelling or inflammation
- Temporary or persistent changes in sensation
- Recurrence or persistence of the underlying condition
For vascular malformations, the location of the lesion and its relationship to nearby nerves, muscles and blood vessels are particularly important considerations.
Your specialist will discuss the potential benefits, risks and alternative treatment options based on your individual condition.
Recovery After Cryoablation
Cryoablation procedures typically take 1 to 2 hours, depending on the size and complexity of the tumor or malformation. Immediate physical recovery is quick, with most patients discharging home either the same day or after an overnight stay for observation. Full recovery and a return to light daily activities usually occur within 3 to 7 days, though temporary soreness, swelling, and bruising around the treated site may persist for 1 to 2 weeks.
Recovery depends on the area treated, the extent of the procedure and the underlying condition. Some patients may experience temporary pain, swelling, bruising or fatigue following treatment.
Your specialist will provide personalised advice regarding activity, wound care, medication and follow-up.
Follow-up imaging may be recommended to assess the treatment area and evaluate the response to treatment.
Patients treated for vascular malformations may require ongoing assessment to determine whether symptoms have improved and whether further treatment is required.
