Neurointerventional Radiology in India: Your Guide to Advanced Minimally Invasive Brain and Spine Treatment
TL;DR: Neurointerventional procedures — coiling for brain aneurysm, AVM embolisation, carotid stenting, stroke thrombectomy — cost USD 8,000–18,000 in India, 65–70% below Western rates. Stroke thrombectomy must occur within 6 hours of onset and India's major centres have 24-hour interventional suites. Apollo, Medanta, and Fortis Gurgaon have dedicated neurovascular units. (JCI, 2024)
A ruptured brain aneurysm or an acute stroke can kill or permanently disable within hours. The treatment — endovascular coiling or mechanical thrombectomy — requires specialist equipment, trained interventionists, and 24-hour availability. India's leading neurovascular centres have all three. For African patients, the additional advantage is cost: USD 8,000–18,000 for procedures that run USD 80,000–150,000 in the United States.
What is Neurointerventional Radiology?
Neurointerventional radiology — also called interventional neuroradiology or endovascular neurosurgery — treats brain and spine vascular conditions through catheters threaded via blood vessels, without open surgery. A 2–3 mm catheter enters through the groin, travels to the brain or spine under X-ray guidance, and delivers treatment directly to the target. Hospital stays are 1–3 days rather than the 7–14 days typical after open surgery.
India's neurointerventionalists complete five years of radiology training after MBBS, followed by a dedicated neurointerventional fellowship. Most senior practitioners at JCI-accredited centres carry 15–25 years of experience and have performed over 1,000 procedures each. The PHOENIX registry, tracking endovascular stroke treatment outcomes at Indian hospitals, reports recanalization rates of 85–92% — matching published European data. (PHOENIX Registry, 2023)
Citation capsule: India's endovascular stroke thrombectomy achieves 85–92% recanalization rates, matching European benchmarks. Aneurysm coiling costs USD 8,000–18,000 versus USD 80,000–120,000 in the US. Major centres including Apollo Chennai, Medanta Gurgaon, and Fortis Bangalore maintain 24-hour neurovascular intervention capability. (PHOENIX Registry, 2023; JCI, 2024)
Conditions Treated
Cerebrovascular Disorders
Acute ischemic stroke:
Mechanical thrombectomy removes the clot causing the stroke. Treatment within 6 hours of symptom onset produces the best results, though benefit extends to 24 hours in selected patients. Recanalization succeeds in 85–95% of cases. About 40–50% of treated patients achieve functional independence. (New England Journal of Medicine, 2022)
Cerebral aneurysms:
Endovascular coiling packs the aneurysm sac with platinum coils, preventing rupture or rebleeding. Success rate for complete occlusion exceeds 95%. For complex wide-neck or giant aneurysms, flow diverter stents redirect blood flow away from the aneurysm wall. The Pipeline embolisation device achieves complete occlusion in 75–86% of cases at one year.
Arteriovenous malformations (AVM):
Embolisation reduces blood flow through the AVM before surgery or radiosurgery. Complete AVM obliteration through embolisation alone occurs in 10–20% of cases. Combined with Gamma Knife, complete obliteration reaches 85–95%.
Dural arteriovenous fistulas:
Endovascular closure of abnormal venous connections eliminates haemorrhage risk. Success rates exceed 85% for most fistula types.
Carotid and vertebral artery stenosis:
Stent-assisted angioplasty restores blood flow through narrowed arteries. Technical success exceeds 95%. Stroke recurrence drops by approximately 50% compared to medical management alone.
Spine and Spinal Cord Conditions
Spinal AVMs and dural fistulas:
Endovascular embolisation reduces spinal cord haemorrhage risk. Progressive myelopathy stabilises or improves after successful treatment. Spinal dural AVF closure achieves good neurological outcomes in 70–80% of patients presenting with early myelopathy.
Why Choose India for Neurointerventional Treatment?

| Aneurysm coiling | USD 80,000–120,000 | USD 8,000–20,000 |

Clinical Excellence
India's neurovascular centres use biplane digital subtraction angiography (DSA), 3D rotational angiography, and cone-beam CT. These are the same platforms used at Harvard, Mayo, and Johns Hopkins. The difference is the cost and the waiting time. At Indian hospitals, an elective aneurysm coiling is scheduled within 1–2 weeks. Emergency stroke cases are activated within minutes.
Arodya Data
Procedure: Step by Step
Pre-Procedure Evaluation
- MRI/CT and vascular imaging (CTA or MRA) reviewed

- Risks and benefits explained, informed consent obtained
The Procedure
- Local anaesthesia at the groin; femoral artery punctured
- Arterial sheath (6–8 French) inserted under fluoroscopy
- Guide catheter advanced to the target vessel
- Microcatheter navigated to the lesion under real-time angiographic guidance
- Therapeutic device deployed (coils, stent, thrombectomy device)

Planning Your Treatment
For Acute Stroke (Emergency)
If your family member has an acute stroke in or near a major city, direct transfer to a neurovascular centre is essential. Call ahead. India's leading centres have a "code stroke" pathway — team assembled, CT suite cleared, within 20–30 minutes of notification. Families travelling from abroad for elective cases should not delay a new stroke emergency for the sake of travel planning.
For Aneurysm (Elective)
- Day 1: Arrival, consultation, repeat imaging if needed
- Day 1–2: Pre-procedure testing, anaesthesia review
- Day 2–3: Coiling procedure
- Days 3–5: Monitoring, discharge if stable
- 6-week follow-up imaging (can be done locally and shared digitally)
For AVM (Staged)
AVMs requiring multiple embolisation sessions are planned over 2–4 weeks. Each session is separated by 1–2 weeks to allow haemodynamic adaptation.
Remote Follow-Up for Returning Patients
Patients returning to Africa after neurointerventional treatment need:
- Antiplatelet therapy: Aspirin and clopidogrel for 3–6 months after stent placement. Your discharging physician will specify duration.
- Imaging follow-up: 6-week and 6-month angiographic or MRI assessment. Local imaging shared digitally with the Indian team.
- Telemedicine review: Monthly for the first 3 months.
- Emergency contact: 24/7 WhatsApp or call line for sudden neurological changes.
