Intracranial Stenting
Intracranial Stents are mesh tubes that act as implants to open clogged brain arteries, which improve blood in flow to the brain for a special subgroup of patients who do not respond to medical treatment and have recurrent stroke symptoms despite best medical therapy. These patients are usually good candidates for intracranial stents. At Supreme Vascular and Interventional Clinic, Dr. Manish Taneja, our neurointervention specialist, offers a continuum of care for neurointerventional treatments such as intracranial stenting.
What is Intracranial Stenting and Does it Treat or Prevent Stroke?
Intracranial stenting is a less commonly known technique to treat stroke or prevent stroke. Blockage of blood vessels to the brain is a common cause of stroke in Asian population affecting up to 25% of patients presenting with acute stroke or transient ischemic attack (TIA) which is a precursor of stroke.
Acute stroke is a “brain attack” and there are two main causes, a blocked artery or leaking or bursting of a blood vessel. TIA is a stroke that lasts only a few minutes. Symptoms of a TIA are like other stroke symptoms, but do not last as long.
Intracranial Stents are mesh tubes that act as implants to open clogged brain arteries, which improve blood in flow to the brain.
Intracranial Stenting Stroke Treatment in Singapore Overview
Intracranial stenting is a minimally invasive neurointerventional procedure used to treat significant narrowing of the arteries inside the brain (intracranial stenosis). This narrowing can reduce blood flow and increase the risk of ischemic stroke.
The procedure involves placing a small stent inside the affected artery to restore and maintain blood flow to the brain.
This treatment is typically considered only after a detailed evaluation of stroke risk, imaging findings, and response to medical therapy. If you are unsure whether this treatment is appropriate, see the decision pathway here, Intracranial stenting decision-making.
The Management of Intracranial Stenting
Usual management is medical treatment requiring aggressive and specific medical therapy to treat these patients. A special subgroup of these patients do not respond to medical treatment and have recurrent stroke symptoms despite best medical therapy. These patients are usually good candidates for intracranial stents. There are dedicated devices designed to treat blocked blood vessels in the brain.
When Intracranial Stenting May Be Recommended
Intracranial stenting may be considered when there is a high risk of stroke due to severe narrowing of a brain artery, especially when medical therapy alone is not sufficient.
Common indications include:
- Severe intracranial arterial stenosis
- Recurrent transient ischemic attacks (TIA) despite medication
- Prior ischemic stroke linked to intracranial narrowing
- Progressive neurological symptoms
- High-risk findings on CT angiography, MR angiography, or cerebral angiography
How the Procedure Works
Intracranial stenting is performed using a minimally invasive endovascular approach:
- A catheter is inserted through an artery (usually in the wrist or groin)
- The catheter is guided to the narrowed brain artery
- A balloon may be used to gently open the narrowing
- A stent is placed to keep the artery open and maintain blood flow
The procedure is performed under imaging guidance in a specialised neurointerventional suite. If you have been told you may need intracranial stenting, obtaining an assessment from an experienced neurointerventional specialist can help confirm the diagnosis, review imaging, and discuss whether intervention is appropriate.

Alternatives to Intracranial Stenting
Not all patients require stenting. In many cases, medical management is the first-line approach.
Alternatives include:
- Antiplatelet therapy (blood-thinning medication)
- Statin therapy to stabilise plaque
- Blood pressure and diabetes control
- Lifestyle modification (smoking cessation, diet, exercise)
- Regular imaging surveillance

Risks and Safety Considerations
As with all neurovascular procedures, intracranial stenting carries some risks. These may include:
- Stroke during or after the procedure
- Blood clot formation in the stent
- Vessel injury or dissection
- Bleeding related to antiplatelet medication
- Restenosis (re-narrowing over time)
These risks are carefully balanced against the risk of untreated severe intracranial stenosis, which may lead to stroke.
Recovery and Follow-Up
After the procedure, patients typically require:
- Observation in a monitored hospital setting
- Antiplatelet medication therapy
- Follow-up imaging to assess stent patency
- Long-term vascular risk factor management
Recovery protocols vary depending on the severity of the underlying condition and individual risk profile.
Who Should Consider Evaluation?
You should consider specialist assessment if you have:
- A history of TIA or stroke
- Known intracranial artery narrowing
- Recurrent neurological symptoms (weakness, speech difficulty, vision changes)
- Abnormal findings on brain vessel imaging
- Uncertainty about whether intervention is required
Related Conditions
This condition is closely linked with other cerebrovascular diseases, including:
- Ischemic stroke and TIA
- Intracranial arterial stenosis
- Carotid artery disease
- Brain aneurysm and neurovascular disorders

Concerned About Brain Artery Narrowing or Stroke Risk?
If you have been diagnosed with intracranial stenosis, have experienced transient ischemic attacks (TIA), or have had a stroke linked to brain artery narrowing, a detailed neurovascular assessment can help determine whether medical therapy or intracranial stenting is appropriate.
A structured evaluation can clarify:
- Whether the artery narrowing is clinically significant
- Whether medical management is sufficient
- Whether intracranial stenting may be indicated
- Your individual risk of future stroke

- Cerebral Angiography Review (if indicated)
- Medical vs Intervention Decision Planning
