Stent-Assisted Coiling in Singapore
A Minimally Invasive Treatment for Selected Wide-Neck Brain Aneurysms
Some brain aneurysms have a wide neck or complex anatomy that makes standard endovascular coiling alone less suitable. In these situations, stent-assisted coiling may provide a safe and effective minimally invasive treatment option.
Stent-assisted coiling is an advanced neurointerventional technique that combines platinum coils with a small permanent stent. The stent acts as a scaffold within the parent artery, supporting coil placement while helping maintain normal blood flow through the blood vessel.
At the Supreme Vascular and Interventional Clinic in Singapore, stent-assisted coiling is performed as part of a comprehensive neurointerventional care pathway led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist. From diagnosis and imaging through treatment planning, the procedure and long-term follow-up, patients receive specialist-led care under one roof.
Every brain aneurysm is unique. Our focus is to understand your aneurysm, explain your treatment options and recommend the most appropriate minimally invasive approach based on your individual condition.

What Is Stent-Assisted Coiling?
Stent-assisted coiling is a specialised form of endovascular coiling used to treat selected brain aneurysms that require additional support during coil placement.
During the procedure, a small permanent stent is positioned across the neck of the aneurysm within the parent artery. Platinum coils are then placed inside the aneurysm through the stent, helping reduce blood flow into the aneurysm while preserving normal blood flow through the artery.
The stent remains in place permanently, providing ongoing support to help keep the coils securely within the aneurysm.
This technique allows many wide-neck or complex aneurysms to be treated using minimally invasive endovascular methods that may not be suitable for standard coiling alone.
When Might Stent-Assisted Coiling Be Recommended?
Stent-assisted coiling may be considered when additional support is required to achieve stable and durable coil placement.
Your specialist may recommend this technique for aneurysms with:
- A wide neck
- Complex anatomy
- An increased risk of coil instability
- Blood vessel anatomy requiring permanent support
Whether stent-assisted coiling is appropriate depends on detailed imaging, aneurysm characteristics and your overall health.
Alternative treatment options may include standard endovascular coiling, balloon-assisted coiling, flow diversion, or surgical clipping, depending on your individual circumstances.

Why Is Treatment Planning So Important?
Every Brain Aneurysm Requires an Individualised Approach
Choosing the most appropriate treatment involves more than selecting a procedure.
Your specialist will carefully assess:
- The aneurysm's size and shape
- Neck width
- Blood vessel anatomy
- Whether the aneurysm has ruptured
- Your overall health
- The potential benefits and risks of each treatment option
At the Supreme Vascular and Interventional Clinic, treatment recommendations are based on advanced imaging, careful clinical assessment and shared decision-making to ensure every patient receives personalised care.
How Does Stent-Assisted Coiling Work?
Providing Long-Term Support for Selected Brain Aneurysms
Stent-assisted coiling is performed using advanced image-guided techniques that allow specialists to treat selected wide-neck or complex brain aneurysms through the blood vessels without the need for open brain surgery.
During the procedure, a thin catheter is carefully guided through the blood vessels to the affected artery in the brain. A small permanent stent is first positioned across the neck of the aneurysm to act as a scaffold. Through the stent, soft platinum coils are then placed inside the aneurysm.
The stent helps keep the coils securely within the aneurysm while maintaining normal blood flow through the parent artery. Over time, the coils encourage clot formation within the aneurysm, helping seal it from the circulation and reduce the risk of rupture or rebleeding.
Throughout the procedure, advanced imaging technology is used to guide precise stent and coil placement and confirm the treatment result before the procedure is completed.
For selected patients, stent-assisted coiling offers an effective minimally invasive treatment when standard coiling alone may not provide sufficient support. Your specialist will determine the most appropriate technique based on the aneurysm's size, shape, location and surrounding blood vessel anatomy.
Balloon-Assisted Coiling vs Stent-Assisted Coiling
| Balloon-Assisted Coiling | Stent-Assisted Coiling |
|---|---|
| Uses a temporary balloon during the procedure | Uses a permanent stent that remains inside the artery |
| Balloon is removed once treatment is complete | Stent continues to support the treated artery after the procedure |
| Suitable for selected aneurysms requiring temporary support | Suitable for selected aneurysms requiring longer-term structural support |
| May not require long-term antiplatelet medication* | Often requires antiplatelet medication as advised by your specialist* |

Potential Benefits of Stent-Assisted Coiling
A Specialised Technique for Selected Brain Aneurysms
Stent-assisted coiling may provide additional support when treating selected wide-neck or complex brain aneurysms. The potential benefits depend on the aneurysm's anatomy and each patient's individual circumstances.
Potential benefits may include:
Permanent Support for Coil Placement
The stent provides a stable scaffold that helps keep the coils securely within the aneurysm while supporting the parent artery.
Treatment for Complex Aneurysms
Stent-assisted coiling expands the range of aneurysms that may be treated using minimally invasive endovascular techniques.
Preservation of Blood Flow
The stent is designed to support treatment while maintaining blood flow through the parent artery.
Durable Long-Term Support
Because the stent remains in place, it continues to provide structural support after the procedure has been completed.
It is important to remember: Every brain aneurysm is unique. Stent-assisted coiling is recommended only when it is considered the most appropriate treatment following a detailed clinical assessment and imaging review.
What Are the Potential Risks and Limitations?
Understanding the Benefits and Risks of Treatment
Like all medical procedures, stent-assisted coiling carries potential risks. Before recommending treatment, your specialist will explain the expected benefits, possible risks and alternative treatment options.
Potential risks may include:
- Bleeding or bruising at the catheter insertion site
- Blood clot formation
- Blood vessel injury
- A small possibility of requiring additional treatment in the future
- Rare reactions to contrast dye or medications used during the procedure
- The need for antiplatelet medication before and after treatment, as advised by your specialist
At the Supreme Vascular and Interventional Clinic, patient safety is supported through careful treatment planning, advanced imaging and specialist-led neurointerventional care.
Recovery After Stent-Assisted Coiling
What Can You Expect After Treatment?
Because stent-assisted coiling is an endovascular (catheter-based) procedure, recovery remains significantly faster than open brain surgery. Recovery varies depending on whether the aneurysm was ruptured or unruptured, the complexity of the procedure and your overall health.
Following treatment, you will be monitored before being discharged or transferred for ongoing care if required.
Your specialist will provide personalised advice on:
- Caring for the catheter access site
- Taking prescribed medications, including antiplatelet therapy where required
- Returning to normal activities
- Follow-up imaging and appointments
- Symptoms that require urgent medical attention
Regular follow-up helps monitor the treated aneurysm, assess the stent and support your long-term recovery Recovery can be fast with minimal scarring. Most patients go home on the same day or within one to two days after treatment. Surgery is done under sedation mostly, with fast and smooth recovery. Patients can generally resume normal daily activities within a short period, following physician guidance regarding temporary physical activity or heavy lifting restrictions.

Frequently Asked Questions About Stent-Assisted Coiling
Why would a stent be used during aneurysm coiling?
A stent may be used to support coil placement when treating selected wide-neck or complex brain aneurysms. It helps keep the coils securely within the aneurysm while maintaining blood flow through the parent artery.
Does the stent remain in the artery after treatment?
Yes. Unlike a balloon used during balloon-assisted coiling, the stent remains permanently within the artery to provide ongoing structural support.
How is stent-assisted coiling different from standard coiling?
Standard coiling places coils directly into the aneurysm, while stent-assisted coiling uses a permanent stent to provide additional support for selected aneurysms.
What is the difference between stent-assisted coiling and flow diversion?
Stent-assisted coiling treats the aneurysm by placing coils inside it, with a stent supporting the coils. Flow diversion uses a specialised device to redirect blood flow away from the aneurysm, without filling it with coils.
Will I need medication after stent-assisted coiling?
Many patients require antiplatelet medication before and after the procedure to help reduce the risk of blood clots forming around the stent. Your specialist will advise you based on your individual treatment plan.
Is stent-assisted coiling suitable for every brain aneurysm?
Stent-assisted coiling is recommended only for selected aneurysms based on their anatomy, location and overall treatment considerations.
