Overview
Minimally invasive endovascular treatment for complex, wide-necked, giant, or fusiform cerebral aneurysms using a flow-diverting stent placed across the parent artery to redirect blood flow away from the aneurysm sac, allowing it to gradually clot and heal over. Leading neurointerventional centers in India and Turkey offer this catheter-based technique for aneurysms unsuitable for clipping or standard coiling.
Your case is matched to a centre on the basis of clinical outcome data, not marketing. We coordinate every step — from pre-operative work-up to post-treatment follow-up — with a dedicated care coordinator.

What Is Flow-Diverter Aneurysm Treatment?
A flow diverter is a densely woven metal mesh stent placed inside the parent blood vessel — not inside the aneurysm itself — to redirect blood flow away from the aneurysm sac. Over weeks to months this allows the aneurysm to gradually clot and heal over while blood continues to flow normally through the treated artery, per the American Association of Neurological Surgeons (AANS).
How it works
The device alters blood flow dynamics at the junction between the aneurysm and the parent artery, promoting gradual thrombosis of the aneurysm followed by tissue healing and growth of a new arterial lining over the stent, per NCBI/StatPearls.
Best suited for
Wide-necked, giant, or fusiform aneurysms, and recurrent aneurysms that have regrown after previous coiling — cases often difficult to treat with clipping or standard coiling alone, per the Society of NeuroInterventional Surgery (SNIS).
Device composition
The most widely used device, the Pipeline Embolization Device, is made of a platinum and nickel-cobalt-chromium alloy mesh with 65–70% porosity, available in a range of diameters and lengths to match the treated artery, per NCBI/StatPearls.
Success rate
Deployment is technically successful in around 95% of procedures, with aneurysm obliteration achieved in the large majority of cases by six-month follow-up angiography, per published systematic reviews (PMC).
The Procedure: Step by Step
Flow-diverter placement is performed entirely through the blood vessels using a catheter, under fluoroscopic (live X-ray) guidance — no open incision into the skull or brain is required.
Anaesthesia and antiplatelet preparation
General anaesthesia is given, and you will typically have started dual antiplatelet medication (such as aspirin and clopidogrel) in the days before the procedure to reduce the risk of clot formation on the device, per SNIS.
Arterial access and catheter navigation
A catheter is inserted through a small puncture, usually in the groin or wrist artery, and carefully navigated through the blood vessels up to the site of the aneurysm using real-time imaging guidance, per AANS.
Flow-diverter deployment
The compressed stent is delivered through the catheter and expanded across the neck of the aneurysm, lining the parent artery so that its mesh redirects blood flow away from the aneurysm sac, per NCBI/StatPearls.
Confirmation imaging and closure
Angiography confirms correct stent position and flow redirection before the catheter is withdrawn; the small puncture site is closed and you are monitored as anaesthesia wears off, per AANS.
Recovery Timeline
Most patients spend a short period in neuro-ICU or a monitored ward for observation before being discharged within a few days, per SNIS.
Many patients return to most normal activities within about a week, though fatigue and soreness at the catheter access site are common initially, per AANS.
Complete recovery from the procedure itself is generally expected by around two weeks, per AANS.
Dual antiplatelet therapy continues for several months per your neurointerventional team's protocol, alongside a schedule of follow-up MRA or DSA imaging to confirm the aneurysm has healed and the artery remains open.

Known Risks & Limitations
- In-stent thrombosis — clot formation on the device — is a key risk, which is why dual antiplatelet therapy and platelet function monitoring are required, per SNIS.
- Perianeurysmal edema and delayed intracranial hemorrhage, including rare delayed rupture of the treated aneurysm before it has fully healed, have been reported, per NCBI/StatPearls.
- In-stent stenosis (narrowing) can develop, typically peaking between six and twelve months after treatment and often improving over the following two years, per PMC long-term outcome studies.
- As with any endovascular neurointervention, ischemic stroke and vessel perforation are possible, and prior stenting at the site may reduce treatment efficacy, per AANS and SNIS.
- As with any procedure involving anaesthesia and blood-thinning medication, there are anaesthesia- and bleeding-related risks your medical team will review with you individually.

The CureSureMedico Care Pathway
Remote clinical review
Share your latest cerebral angiography (DSA/MRA/CTA) and neurosurgical notes. Our coordination team forwards your case to a neurointerventional specialist to confirm whether flow diversion is anatomically appropriate for your aneurysm.
Device and neuro-ICU capacity matching
Your partner centre confirms flow-diverter device availability and neuro-ICU/angiography suite capacity before your estimate is finalised, so travel can be scheduled around a confirmed procedure date.
Consolidated estimate
A cost estimate covering the procedure, flow-diverter implant, neuro-ICU and hospital stay, and initial follow-up imaging is issued before you travel.
Procedure and monitored recovery
Your care team monitors your recovery in the neuro-ICU and ward, confirming correct antiplatelet dosing and completing pre-discharge imaging before you are cleared to travel home.
Long-term surveillance handover
Because flow diversion requires an ongoing antiplatelet regimen and a schedule of follow-up angiographic imaging, a treatment summary and recommended monitoring plan are shared with your home neurologist or neurosurgeon so this care continues seamlessly after you return home.

Frequently asked questions
Unlike coils placed inside the aneurysm sac, a flow diverter is placed across the parent artery itself. Its dense mesh redirects blood flow away from the aneurysm, causing it to gradually clot and shrink over weeks to months while blood flow to the brain continues normally through the treated vessel.
