Embolisation in Singapore
Minimally Invasive, Image-Guided Treatment
Embolisation is a minimally invasive, image-guided procedure used to intentionally reduce or stop blood flow through selected blood vessels. During embolisation, a specialist guides a thin catheter through the blood vessels to the targeted area and delivers specialised embolic materials to the selected vessel.
Depending on the condition being treated, embolisation may be used to control bleeding, reduce abnormal blood flow, treat vascular malformations, block blood supply to a tumour, or manage other vascular conditions.
The type of embolisation performed depends on the underlying condition, the location of the abnormal blood vessels and the pattern of blood flow.
At the Supreme Vascular and Interventional Clinic, treatment is individually planned using appropriate vascular imaging and minimally invasive techniques.
Care is led by Dr. Manish Taneja, providing specialist vascular and interventional expertise with a continuum of care under one roof.

What Is Embolisation?
Embolisation is a catheter-based procedure that deliberately blocks or reduces blood flow through a selected blood vessel. A thin catheter is introduced through a small vascular access point and guided towards the area requiring treatment.
Once the target vessel has been identified using imaging, an appropriate embolic material is delivered through the catheter. The material reduces blood flow through the selected vessel while the surrounding healthy circulation is preserved as much as possible.
Embolisation can therefore be used for very different medical conditions, depending on the blood vessels involved and the purpose of treatment.
How Does Embolisation Work?
Targeting Abnormal or Unwanted Blood Flow
Your symptoms, medical history and previous investigations are first reviewed. Appropriate imaging is used to understand the relevant blood vessels and blood-flow patterns.
A small catheter is introduced through an appropriate blood vessel either through the groin or wrist area. The catheter is carefully guided towards the target vessel.
Angiography or other imaging is used to confirm the vascular anatomy. A selected embolic material is delivered through the catheter.
The material reduces or blocks blood flow through the targeted vessel. Further imaging is performed to assess the treatment result. The catheter is removed and the access site is monitored after the procedure.
Why Is Embolisation Performed?
Embolisation can serve different treatment purposes depending on the condition.
Control Bleeding
Embolisation can be used to reduce blood flow from a bleeding blood vessel in selected situations.
Treat Vascular Malformations
Abnormal blood vessels within selected vascular malformations can be targeted to reduce abnormal blood flow.
Treat Tumours
Some tumours receive a significant blood supply from specific arteries. Embolisation can reduce this blood supply in selected cases.
Treat Aneurysms
Embolic materials can be used to block blood flow within selected aneurysms and prevent further filling.
Manage Abnormal Venous Flow
Selected venous conditions can also be treated using embolisation.
Support Other Treatments
Embolisation may be performed before surgery or another treatment to reduce blood flow and make subsequent treatment more manageable.
Types of Embolisation
Different Conditions Require Different Embolisation Approaches
The term embolisation describes the technique rather than one single treatment.
At the Supreme Vascular and Interventional Clinic, different embolisation procedures may be used depending on the underlying condition.
Neurovascular Embolisation
Embolisation can be used to treat selected conditions involving the blood vessels of the brain and head.
Examples include:
Vascular Malformation Embolisation
Embolisation can be used for selected vascular malformations, particularly those with suitable high-flow characteristics.
Examples include:
- Head and neck vascular malformation embolisation
- Arteriovenous malformation embolisation
- Selected peripheral vascular malformations
Tumour Embolisation
Tumour embolisation reduces blood flow to selected vascular tumours or tumour-related bleeding.
Examples include:
- Tumour embolisation
- Pre-operative tumour embolisation
- Selected interventional oncology procedures
Pelvic Embolisation
Embolisation can be used to treat selected vascular conditions affecting the pelvis.
Peripheral and Other Vascular Embolisation
Selected vascular conditions affecting other parts of the body may also be treated using embolisation. In women, embolisation may be used for conditions such as uterine fibroids. In men, embolisation may be used for varicocele, benign prostatic enlargement (benign prostatic hyperplasia), and selected cases of vascular erectile dysfunction, including venous leak. These procedures use minimally invasive, image-guided techniques to target the abnormal blood vessels contributing to the condition.
Peripheral & Musculoskeletal Embolisation
Embolisation can also be used to target selected abnormal blood vessels outside the brain and major organs.
Genicular Artery Embolisation (GAE) is a minimally invasive procedure that targets selected blood vessels around the knee. It may be considered for certain patients with chronic knee pain associated with osteoarthritis, where abnormal blood vessel growth and inflammation around the joint may contribute to symptoms.
What Embolic Materials Are Used?
Different embolic materials may be selected depending on the blood vessel and condition being treated.
These may include:
- Coils
- Vascular plugs
- Particles
- Liquid embolic agents
- Other specialised embolic materials
The choice depends on factors such as vessel size, blood-flow characteristics, treatment location and the purpose of embolisation. Your specialist will determine the most appropriate material for your individual treatment.
Is Embolisation Minimally Invasive?
Yes. Embolisation is performed through a small catheter rather than through conventional open surgery.
The catheter allows the specialist to reach the targeted blood vessel from within the vascular system. This approach can provide precise treatment while limiting the need for a large surgical incision.
The extent of treatment and recovery depends on the specific embolisation procedure being performed.
Potential Benefits of Tumour Embolisation
A Targeted, Minimally Invasive Approach to Vascular Treatment
For appropriately selected patients, embolisation may offer several potential benefits.
Minimally Invasive
Treatment is performed using catheter-based vascular access.
Targeted
The procedure focuses on specific blood vessels responsible for the condition being treated.
Image-Guided
Angiography and other imaging techniques allow the vascular anatomy to be visualised during treatment.
Can Treat Different Conditions
Embolisation can be adapted to treat a wide range of vascular conditions.
May Avoid or Support Surgery
In selected cases, embolisation can provide an alternative to surgery or be used before another procedure.
Can Be Performed as Part of a Staged Treatment
Some complex vascular conditions require multiple treatment sessions or a combination of approaches.
What Are the Potential Risks and Considerations?
Understanding What to Expect
Embolisation is minimally invasive, but like any vascular procedure it has potential risks.
These may include:
- Temporary discomfort or bruising
- Minor bleeding at the catheter access site
- Temporary swelling or inflammation
- Reaction to contrast material
- Blood vessel irritation
- Unintended effects on nearby vessels
- Recurrence or persistence of the underlying condition
- The possibility of requiring additional treatment
The risks vary significantly depending on the type and location of embolisation.
Your specialist will explain the specific considerations relevant to your procedure before treatment.
Recovery After Embolisation
What Can You Expect After Treatment?
Recovery varies considerably depending on the type of embolisation performed. Some procedures involve relatively short recovery, while more complex embolisation treatments may require closer monitoring.
Many embolizations are a same-day discharge treatment that allows you to return home afterwards and certain targeted embolizations (or complex neurovascular treatments) require an overnight stay (1 to 2 days). Most patients can resume light, everyday daily activities within 24 to 48 hours and full recovery takes generally 1 week.
Your aftercare may include:
- Monitoring the catheter access site
- Resting after the procedure
- Taking prescribed medication
- Temporarily avoiding strenuous activity
- Attending follow-up appointments
- Further imaging where required
Your specialist will provide personalised recovery instructions based on your treatment.

Frequently Asked Questions About Embolisation
What is embolisation used to treat?
Embolisation can be used for selected aneurysms, vascular malformations, tumours, bleeding blood vessels and other vascular conditions.
How does embolisation work?
A catheter is guided to the target blood vessel and an embolic material is delivered to reduce or stop blood flow through that vessel.
What embolic materials are used?
Selected tumours with an identifiable and accessible blood supply may be considered, although suitability depends on the individual tumour.
Is embolisation the same as sclerotherapy?
No. Embolisation generally uses catheter-based treatment to target blood vessels, while sclerotherapy involves injecting a sclerosing medication directly into selected vascular malformations.
Can embolisation be used before surgery?
Yes. In selected cases, embolisation may be performed before surgery to reduce blood flow to the treatment area.
Does embolisation always require surgery afterwards?
Embolisation procedures are used as standalone treatments, while others form part of a broader treatment plan.
Can embolisation be repeated?
Yes. Some complex vascular conditions may require staged or repeat embolisation treatments.
How long does recovery take?
Recovery depends on the type and extent of embolisation and varies between individuals. Many routine peripheral embolizations allow you to return home the same day and certain targeted embolizations (or complex neurovascular treatments) require an overnight stay (1 to 2 days). Most patients can resume light, everyday daily activities within 24 to 48 hours and full recovery takes generally 1 week.
