Varicocele Embolisation in Singapore
Minimally Invasive Treatment for Varicocele
Varicocele embolisation is a minimally invasive, image-guided procedure used to treat a varicocele, which is an enlargement of the veins within the scrotum.
A varicocele can sometimes cause discomfort, affect testicular function or be associated with reduced fertility.
During embolisation, a thin catheter is guided through the veins towards the affected testicular veins. Small embolic materials are then used to block the abnormal veins and redirect blood flow through healthier veins.
At the Supreme Vascular and Interventional Clinic, varicocele embolisation is considered after a detailed assessment of your symptoms, medical history and vascular anatomy.
Care is led by Dr. Manish Taneja, providing specialist vascular and interventional expertise with a continuum of care under one roof.

What Is Varicocele?
A varicocele is an enlargement of the veins within the scrotum, similar in principle to varicose veins. It most commonly occurs on the left side but can occur on either side or both sides.
Varicoceles may not cause any symptoms and can sometimes be discovered during a routine examination or fertility assessment.
When symptoms occur, they may include:
- A dull or aching scrotal discomfort
- A feeling of heaviness
- Discomfort that becomes more noticeable after standing or physical activity
- Visible or enlarged scrotal veins
- Changes in testicular size or development
- Fertility concerns
Not every varicocele requires treatment.
What Is Varicocele Embolisation?
Varicocele embolisation is a minimally invasive procedure used to block selected veins responsible for the abnormal blood flow associated with a varicocele.
Rather than surgically removing or tying off the affected veins, embolisation uses a catheter to reach the abnormal veins from inside the blood vessel.
Small embolic materials are then placed within the targeted veins. This redirects blood flow through other healthy veins. The procedure is performed using image guidance to help identify the relevant venous anatomy and accurately deliver the treatment.

How Does Varicocele Embolisation Work?
Blocking the Abnormal Veins From Within
Your symptoms, medical history and previous investigations are first reviewed.
Your specialist assesses the suspected varicocele and relevant venous anatomy.
A small catheter is introduced through an appropriate blood vessel usually through the groin or wrist. The catheter is carefully guided towards the affected testicular veins.
Venography is performed to visualise the veins and confirm the treatment approach. Small embolic materials are delivered into the selected abnormal veins. The catheter is removed and the access site is monitored.
Follow-up is arranged to assess your recovery and clinical response.
When Might Varicocele Embolisation Be Considered?
Varicocele embolisation may be considered for selected patients with a symptomatic or clinically significant varicocele.
Your specialist may consider treatment when there is:
- Persistent scrotal discomfort
- A clinically significant varicocele
- Testicular changes associated with the varicocele
- Fertility concerns
- Abnormal semen analysis in appropriate circumstances
- A previous varicocele treatment that has not fully resolved the condition
- A preference for a minimally invasive treatment approach
The decision to treat depends on your symptoms, examination findings, fertility considerations and overall health.
Varicocele and Male Fertility
Understanding the Potential Relationship
Varicoceles are commonly evaluated in men experiencing fertility difficulties.
The enlarged veins associated with a varicocele may affect the local environment around the testicle and, in some patients, may be associated with changes in sperm production or quality.
However, not every man with a varicocele will experience fertility problems. Fertility is influenced by many factors, so treatment decisions should be based on an individual's clinical assessment and fertility evaluation.
Where appropriate, varicocele treatment may form part of a broader fertility management plan.
Varicocele Embolisation for Scrotal Discomfort
A Minimally Invasive Option
Some patients with a varicocele experience a persistent dull or aching discomfort in the scrotum.
Symptoms may become more noticeable after prolonged standing, physical activity or towards the end of the day.
When a varicocele is considered to be contributing to the symptoms and conservative measures have not provided sufficient relief, treatment may be considered.
Varicocele embolisation offers a minimally invasive approach that targets the abnormal veins responsible for the varicocele.
Potential Benefits of Varicocele Embolisation
A Minimally Invasive Approach to Varicocele Treatment
For appropriately selected patients, varicocele embolisation may offer several potential benefits.
Minimally Invasive
The procedure is performed through a small catheter rather than open surgery.
No Surgical Incision in the Scrotum
The abnormal veins are treated from within the vascular system.
Image-Guided Precision
Venography helps identify the relevant veins and guide treatment.
Targeted Treatment
Embolisation focuses on the veins responsible for the abnormal blood flow.
Outpatient Treatment
Many patients can undergo the procedure as a day procedure, depending on their individual circumstances.
Relatively Short Recovery
Recovery is generally shorter than more invasive surgical approaches.
Can Be Considered for Recurrent Varicocele
Embolisation may be an option in selected patients whose varicocele has returned following previous treatment.
Varicocele Embolisation vs Varicocelectomy
Understanding the Different Approaches
Both embolisation and varicocelectomy are established approaches to treating varicocele, but they use different techniques.
| Varicocele Embolisation | Varicocelectomy |
|---|---|
| Minimally invasive catheter procedure | Surgical procedure |
| Accesses the veins from within the vascular system | Surgically accesses and treats affected veins |
| Uses embolic material to block selected veins | Uses surgical ligation or division of affected veins |
| No conventional surgical incision in the groin or scrotum | Requires surgical access |
| Usually performed as a day procedure | Recovery varies according to surgical approach |
| Image-guided | Performed using surgical visualisation and/or microscopy |
Neither approach is automatically appropriate for every patient.
Your specialist will consider your individual anatomy, symptoms, previous treatment and treatment preferences.
Can Varicocele Embolisation Treat Recurrent Varicocele?
Yes. Varicocele embolisation may be considered for selected patients whose varicocele has returned following previous treatment.
A recurrent varicocele can sometimes be associated with persistent or newly developed abnormal venous drainage.
Imaging can help identify the relevant venous anatomy and determine whether embolisation may be appropriate.
The cause of recurrence and the previous treatment approach are important considerations when planning further treatment.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Varicocele embolisation is minimally invasive, but like any vascular procedure it has potential risks.
These may include:
- Temporary discomfort
- Bruising at the catheter access site
- Minor bleeding
- Reaction to contrast material
- Temporary scrotal discomfort or swelling
- Recurrence or persistence of the varicocele
- The possibility of requiring additional treatment
Your individual risks depend on your venous anatomy, medical history and the specific embolisation technique used.
Your specialist will explain the expected benefits, potential risks and alternatives before treatment.
Recovery After Varicocele Embolisation
What Can You Expect After Treatment?
Recovery following an uncomplicated varicocele embolisation is generally relatively short. The procedure takes 30-45 minutes and many patients can return to normal activities after a day or two.
After treatment, you may be advised to:
- Rest for a short period
- Keep the catheter access site clean and dry
- Avoid strenuous physical activity temporarily
- Follow your medication instructions
- Wear supportive underwear if recommended
- Monitor for increasing pain or swelling
- Attend follow-up appointments
Your specialist will provide personalised recovery instructions based on your procedure and individual circumstances.
