Overview
Emergency endovascular clot retrieval for acute ischemic stroke caused by a large vessel occlusion. In thrombectomy, "time is brain" — current American Stroke Association guidance supports treatment within 6 hours of symptom onset for most patients, extending to 24 hours for carefully selected patients on advanced imaging. This is fundamentally an emergency-department procedure performed at the nearest capable stroke center, not a plannable medical-tourism journey — this page exists to explain the procedure and its realistic role in international care, primarily around post-acute follow-up, second opinions, and rehabilitation after stabilization.
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.

This Is a Time-Critical Emergency Procedure
Mechanical thrombectomy is performed emergently for acute ischemic stroke — "time is brain," and outcomes depend on treatment within hours of symptom onset. If you or someone with you is having stroke symptoms, call emergency services and go to the nearest stroke-capable hospital immediately. This page is provided for education and for planning post-acute care; it is not a substitute for emergency care, and international medical travel for the acute procedure itself is not realistic.
Stent Retriever vs. Aspiration Thrombectomy
Neurointerventionalists use one of two main catheter-based techniques to remove the clot causing a large vessel occlusion stroke. The choice depends on clot location, vessel anatomy, and operator experience.
| Parameter | Stent Retriever Thrombectomy | Aspiration (Direct Clot Aspiration) Thrombectomy |
|---|---|---|
| What it is | A mesh device is threaded past the clot, expanded to capture it, and withdrawn along with the catheter, per NCBI/StatPearls. | A catheter is advanced to the clot and used to suction it out directly, without a separate capture device, per NCBI/StatPearls. |
| Clinical outcomes | Meta-analyses show broadly similar safety, reperfusion rates, and 90-day clinical outcomes compared to aspiration thrombectomy. | Meta-analyses show broadly similar safety, reperfusion rates, and 90-day clinical outcomes compared to stent retriever thrombectomy; some individual studies report shorter procedure times with aspiration. |
| Technique selection | Often preferred for tortuous vessel anatomy or when a device can be safely navigated past the clot. | Often used as a first-pass approach, with conversion to a stent retriever or combined technique if aspiration alone does not achieve reperfusion. |
| Eligibility window | Per current American Stroke Association guidance, thrombectomy is recommended within 6 hours of symptom onset for most eligible patients with anterior circulation large vessel occlusion, extending to 24 hours for carefully selected patients based on advanced imaging. | The same time-window eligibility criteria apply regardless of which technique is used, since eligibility is determined by imaging and clinical status, not by the retrieval technique. |
The Procedure: Step by Step
The steps below outline the general mechanical thrombectomy process for acute ischemic stroke. This procedure is performed emergently at a stroke-capable hospital, not on a planned or scheduled basis.
Rapid imaging and eligibility confirmation
CT or MR imaging (including CT angiography) confirms a large vessel occlusion and rules out hemorrhage, establishing eligibility for thrombectomy and, where applicable, IV thrombolysis.
Femoral or radial arterial access
Under local anesthesia with sedation (general anesthesia is used in select cases), the neurointerventionalist accesses an artery, typically at the groin or wrist, and advances a catheter toward the brain under imaging guidance.
Clot retrieval
A stent retriever or aspiration catheter is used to remove the clot from the occluded vessel, restoring blood flow to the affected brain tissue, per the Society of NeuroInterventional Surgery.
Neuro-ICU monitoring
After the procedure, the patient is monitored closely in a neuro-ICU or dedicated stroke unit for blood pressure control, neurological status checks, and early detection of complications such as bleeding or re-occlusion.
Recovery Timeline
Close neurological and blood pressure monitoring in a neuro-ICU or stroke unit; follow-up imaging is typically performed to confirm reperfusion and check for bleeding.
Inpatient stroke unit care continues, with early mobilization, swallowing assessment, and initiation of physiotherapy, occupational therapy, and speech therapy as needed.
Many patients transition to a structured neuro-rehabilitation programme; the extent of neurological recovery varies widely and depends on how quickly treatment was received and the stroke's severity and location.
Secondary stroke-prevention measures (blood pressure and cholesterol management, antiplatelet or anticoagulant therapy, and treatment of underlying causes such as carotid stenosis or atrial fibrillation) continue long-term under a neurologist's care.

Known Risks & Limitations
- Mechanical thrombectomy carries risks including bleeding (including symptomatic intracranial hemorrhage), vessel injury or perforation, re-occlusion, and, in rare cases, embolization of clot fragments to previously unaffected vessels.
- Benefit is highly time-dependent: outcomes are best when treatment begins within 6 hours of symptom onset, and delays of even minutes can reduce the amount of brain tissue that can be saved.
- Not every stroke patient is a candidate — eligibility depends on the occlusion being in a treatable vessel, imaging findings, and time since symptom onset, as determined by the treating stroke team, not by patients or families.
- Even with successful clot removal and reperfusion, some degree of neurological deficit may remain permanently; thrombectomy restores blood flow but cannot always reverse tissue damage that has already occurred.

Where CureSureMedico Can Realistically Help
This is not a plannable trip
Because thrombectomy must happen within hours of stroke onset, it is not something you can arrange international travel for in advance — patients present acutely at their nearest hospital and are treated there.
Post-acute second opinion
Once you are medically stabilized, our coordination team can arrange a remote second opinion on your imaging and treatment course from a partner neurologist or neurointerventionalist.
Rehabilitation programme matching
We help match stabilized patients to accredited neuro-rehabilitation centres abroad, including access to structured physiotherapy, speech therapy, and occupational therapy programmes.
Secondary prevention evaluation
For patients wanting to reduce future stroke risk, we can arrange evaluation for elective procedures such as carotid endarterectomy or carotid stenting once you are stable.

Frequently asked questions
No. Acute ischemic stroke is a medical emergency where outcomes depend on treatment within hours — "time is brain," and every minute of delay costs neurons. You should call emergency services and go to the nearest stroke-capable hospital immediately; international travel is not appropriate during an active stroke. Because of this, international medical coordination for thrombectomy itself is unusual: patients present acutely at their local hospital and are treated there. We are transparent that CureSureMedico's role here is limited during the emergency itself, and we want you to understand that limitation rather than overstate our relevance to the acute event.
