Intracranial Stenting in Singapore
Minimally Invasive Treatment for Selected Narrowed Brain Arteries
Intracranial stenting is a minimally invasive endovascular procedure used to treat selected patients with significant narrowing of an artery within the brain.
Intracranial artery narrowing, also known as intracranial arterial stenosis, can reduce blood flow to the brain and may increase the risk of transient ischaemic attacks (TIAs) or ischaemic stroke.
During intracranial stenting, a specialist guides a catheter through the blood vessels to the narrowed artery. A small stent is then positioned across the affected area to help support the artery and maintain blood flow.
At the Supreme Vascular and Interventional Clinic, intracranial stenting forms part of a comprehensive neurointerventional care pathway led by Dr. Manish Taneja, a dual-trained neurointerventional and peripheral vascular intervention specialist.
With expertise spanning vascular conditions affecting both the brain and body, our specialized clinic provides a brain-to-body approach to vascular assessment, treatment planning and ongoing care.

What Is Intracranial Stenting?
Intracranial stenting is an endovascular treatment that uses a small mesh stent to support an artery that has become significantly narrowed within the brain.
Intracranial artery stenosis may occur when plaque or other changes cause the inner passage of an artery to become narrower. Reduced blood flow can contribute to neurological symptoms and increase the risk of stroke in selected patients.
During treatment, a thin catheter is guided through the blood vessels to the affected artery. The narrowed area may be treated with angioplasty before a stent is positioned to support the artery and help maintain its opening.
Intracranial stenting is a specialised treatment and is not appropriate for every patient with brain artery narrowing. Careful assessment of symptoms, imaging, medical history and previous treatment is essential before considering intervention.
How Does Intracranial Stenting Work?
Supporting a Narrowed Artery Within the Brain
Before treatment, detailed brain and blood vessel imaging is used to identify the location and severity of the arterial narrowing and assess the surrounding blood vessels. During the procedure, a thin catheter is carefully inserted through the groin or wrist thenguided through the blood vessels towards the affected intracranial artery. The narrowed section may first be gently widened using angioplasty. A small stent is then positioned across the narrowed area to provide structural support and help maintain blood flow through the artery.
The stent remains permanently in place after the procedure while the catheter and temporary equipment are removed. Advanced imaging is used throughout treatment to guide accurate positioning and assess blood flow through the treated artery.
It is important to remember: Intracranial stenting treats narrowing within an artery of the brain, helping support the blood vessel and maintain blood flow to the areas of the brain it supplies.
When Might Intracranial Stenting Be Recommended?
Intracranial stenting may be considered for selected patients with significant intracranial artery narrowing, particularly when there is a high risk of recurrent ischaemic events despite appropriate medical treatment.
Your specialist will consider:
- The degree of arterial narrowing
- The location of the stenosis
- Whether you have experienced a TIA or stroke
- Your response to medical treatment
- Brain and blood vessel imaging
- Your overall health
- The potential benefits and risks of intervention
Not every patient with intracranial artery stenosis requires a stent.
Depending on your individual circumstances, treatment may instead involve medical management, risk-factor control and close monitoring. The decision to proceed with intracranial stenting requires careful specialist assessment.
Intracranial Stenting vs Medical Treatment
Why Treatment Decisions Need to Be Individualised
The discovery of intracranial artery narrowing does not automatically mean that a procedure is required.
Medical treatment and management of vascular risk factors are important components of care for patients with intracranial artery disease.
Depending on your condition, your treatment plan may include:
- Medication to reduce the risk of blood clots
- Blood pressure management
- Cholesterol management
- Diabetes management
- Lifestyle and risk-factor modification
- Imaging surveillance
- Endovascular treatment in selected circumstances
For patients who continue to experience neurological events despite appropriate medical management, or who meet other clinical criteria, an endovascular approach may be considered.
Your specialist will weigh the potential benefits and risks of intervention against continued medical management.
Intracranial Stenting vs Carotid Artery Stenting
Although both procedures use a stent to support a narrowed artery, they treat different parts of the circulation.
| Intracranial Stenting | Carotid Artery Stenting |
|---|---|
| Treats arteries located within the brain | Treats the carotid arteries in the neck |
| Used for selected intracranial artery stenosis | Used for selected carotid artery stenosis |
| Requires specialised neurointerventional techniques | Uses endovascular vascular techniques |
| Treatment planning relies heavily on brain and vascular imaging | Treatment planning focuses on the carotid arteries and their blood flow to the brain |
| Aims to support blood flow through a narrowed brain artery | Aims to improve blood flow through a narrowed carotid artery |
Potential Benefits of Intracranial Stenting
Supporting Blood Flow Through a Narrowed Brain Artery
For appropriately selected patients, intracranial stenting may provide potential benefits.
Supports the Narrowed Artery
The stent provides structural support to help maintain the opening of the treated artery.
May Improve Blood Flow
Opening the narrowed section may improve blood flow through the affected intracranial artery.
Minimally Invasive Approach
The procedure is performed through the blood vessels using catheter-based techniques rather than open brain surgery.
Provides an Option for Selected Patients
Intracranial stenting may be considered when a patient remains at significant risk despite appropriate medical management.
It is important to remember: Every patient is different. Intracranial stenting is a specialised treatment and should only be considered after detailed assessment of the patient's symptoms, imaging and individual risk.
What Are the Potential Risks and Limitations?
Understanding the Risks of Intracranial Stenting
Intracranial stenting is a specialised procedure and carries potential risks.
Potential risks may include:
- Blood vessel injury
- Re-narrowing of the treated artery
- Damage to the artery during treatment
- Bleeding or bruising at the catheter access site
- Reaction to contrast dye
The risks depend on the location and severity of the arterial narrowing, the patient's medical history and the complexity of treatment. Patients may experience some bruising or soreness around the incision point, but this should also heal in a fairly short amount of time.
Your specialist will explain the potential benefits, risks and alternative treatment options before recommending intervention.
Recovery After Intracranial Stenting
What Can You Expect After Treatment?
Following intracranial stenting, you will be monitored to assess your neurological condition, blood pressure and recovery. Recovery from intracranial stenting is remarkably mild. Patients may be tired for a few days after the procedure, but often return to normal life after 3 to 7 days.
Your specialist will provide personalised advice regarding:
- Prescribed medications
- Caring for the catheter access site
- Returning to normal activities
- Follow-up appointments
- Follow-up brain and vascular imaging
- Managing vascular risk factors
It may be necessary to monitor arteries to ensure any plaque-forming conditions do not develop a new risk location. Long-term follow-up is important to monitor the treated artery and reduce the risk of future neurological events.
Your recovery will depend on your individual condition and whether you experienced a TIA or stroke before treatment.
