Vertebral artery angioplasty and stenting in Turkey: what it is and how it works
Vertebral artery angioplasty and stenting is an endovascular procedure that restores blood flow through severely narrowed vertebral arteries to the brain. The two vertebral arteries ascend through the neck and unite at the base of the skull to form the basilar artery. Together, they create the posterior cerebral circulation, supplying oxygenated blood to the brainstem, cerebellum, and occipital lobes. When atherosclerotic plaque narrows these vessels—most commonly at the origin where the vertebral artery branches from the subclavian artery—the restricted blood supply can cause transient ischaemic attacks (TIAs) or severe posterior circulation strokes.
During the intervention, an endovascular specialist inserts a narrow catheter through an artery in the wrist or groin and navigates it to the blockage under continuous X-ray guidance. A micro-balloon expands the narrowed segment, and a permanent metallic stent is deployed to keep the vessel open. Hospitals in Turkey perform this procedure in modern catheterisation suites. For an overview of cranial and neurovascular care, see our guide to neurosurgery treatments in Turkey.
Does vertebral artery angioplasty and stenting work to prevent stroke?
Yes, for patients with recurrent symptoms despite medication. Clinical studies confirm that the procedure successfully opens blocked arteries in over 95% of cases. However, major randomised trials, including the VIST and VAST studies, show that stenting is not required for every patient with vertebral narrowing. Its clinical benefit depends on whether the stenosis causes ongoing symptoms and where the plaque is located.
For narrowing at the vertebral artery origin in the neck (extracranial stenosis), stenting provides a reliable channel with a low rate of procedural complications. It is most beneficial for patients who continue to experience symptoms such as vertigo, double vision, or unsteadiness while taking blood-thinning medication. For narrowing inside the skull (intracranial stenosis), procedure risks are higher, and doctors generally recommend intensive medical therapy first. A trustworthy medical team will evaluate your imaging carefully and will not recommend stenting for asymptomatic narrowing.
Vertebral artery angioplasty and stenting cost in Turkey compared with the UK, US and Germany
The figures below show approximate price ranges for the procedure and hospital stay, not individual hospital quotes. Final costs depend on the catheter technique, stent type, and hospitalisation tier. Each clinic confirms its exact fee after reviewing your imaging scans.
| Country | Approximate cost range |
|---|---|
| Turkey | €4,500 – €9,500 |
| United Kingdom | €11,000 – €22,000 |
| United States | €28,000 – €55,000 |
| Germany | €12,000 – €24,000 |
Key factors that influence the vertebral artery angioplasty and stenting price include the type of stent selected (balloon-expandable, self-expanding, or drug-eluting), whether vascular access is radial or femoral, and the length of monitoring in intermediate care. In Turkey, standard packages typically include pre-operative consultations, blood tests, digital subtraction angiography, the procedure itself, one to two nights in hospital, follow-up checks, and airport transfers.

Comparing endovascular stenting, intensive medical therapy and surgical transposition
Vertebral stenosis can be managed with medication, endovascular stenting, or open surgery. The table below outlines how these treatment paths compare.
| Method | Best suited to | Typical limits |
|---|---|---|
| Vertebral artery angioplasty and stenting | Symptomatic narrowing refractory to medical therapy | Risk of in-stent restenosis; requires ongoing antiplatelet therapy |
| Intensive medical therapy | Asymptomatic stenosis or first presentation of mild narrowing | Does not physically widen severely blocked vessels |
| Surgical vertebral transposition | Extracranial origin narrowing when catheter access fails | Invasive open neck operation with longer recovery |
Intensive medical management—combining dual antiplatelet drugs, high-dose statins, and blood pressure control—is the standard initial approach for all patients. Stenting is indicated when transient ischaemic symptoms persist despite medication. Open surgical transposition, where the vertebral artery is surgically reconnected to the common carotid artery, is reserved for rare anatomical situations where endovascular catheter access is not possible.
Who is a good candidate for vertebral stenting, and who is not?
Good candidates are patients with confirmed, high-grade vertebral artery stenosis (usually 50% to 70% or greater) who experience recurrent vertebrobasilar symptoms despite medication. Common symptoms include recurrent vertigo, loss of balance (ataxia), double vision (diplopia), drop attacks, or transient weakness. Candidates must also be medically fit to tolerate antiplatelet therapy after the operation.
You are less suited to stenting if your arterial narrowing was discovered incidentally and produces no symptoms, as medical therapy is safer in such cases. The procedure is also not recommended for completely blocked arteries that a guidewire cannot safely cross, patients with active internal bleeding who cannot take blood thinners, or individuals with severe, irreversible brain damage from past strokes.
The procedure step by step: anaesthesia, access and stent placement
Vertebral stenting is performed in an advanced angiography cath lab and typically takes 60 to 90 minutes. The procedure follows five steps:
- Preparation and access: Local anaesthesia numbs the wrist (radial artery) or groin (femoral artery) entry point. Light sedation keeps you relaxed and comfortable while awake for neurological checks.
- Catheter navigation: A guide catheter advances under fluoroscopic X-ray guidance to the subclavian artery, positioned at the vertebral artery origin.
- Crossing the stenosis: A fine micro-guidewire carefully crosses the narrowed arterial segment under angiographic roadmapping.
- Balloon angioplasty and stenting: A balloon catheter inflates briefly to open the narrowed passage, followed by deploying a vascular stent to scaffold the vessel open.
- Completion and closure: Final angiograms confirm restored blood flow to the basilar artery. Catheters are withdrawn and the puncture site is sealed with a closure device or compression band.
Angiographic before and after: what imaging shows and what stenting cannot reverse
Because vertebral stenting is a vascular operation, "before and after" results are assessed through medical imaging rather than physical appearance. Diagnostic angiograms taken immediately before the procedure display severe vessel narrowing with delayed blood flow. Post-stent imaging demonstrates immediate restoration of the arterial lumen, with rapid, unobstructed contrast flow reaching the brainstem and cerebellum.
In clinical terms, successful treatment resolves transient symptoms such as dizziness on head movement, blurred vision, and sudden unsteadiness. However, patients should understand what stenting cannot achieve: it cannot restore brain tissue that was permanently damaged by earlier completed strokes. The primary objective is preventing future ischaemic events. Follow-up Doppler ultrasound or CT angiography at six and twelve months monitors the treated artery to ensure the stent remains open.
Your trip to Turkey and vertebral artery angioplasty and stenting recovery
Most international patients plan a stay of five to seven nights in Turkey. This timeline allows for pre-procedure checks, the intervention, hospital monitoring, and a follow-up review before flying home.
Following the procedure, you will spend 12 to 24 hours in intermediate care or a high-dependency unit for continuous neurological and blood pressure monitoring. If the femoral artery in the groin was used, you must lie flat for four to six hours to allow the puncture site to seal; radial wrist access allows you to sit up much sooner. Most patients are discharged from hospital after one to two nights.
At your hotel, you can walk gently and rest while continuing your prescribed dual antiplatelet medication. A follow-up consultation takes place four to five days post-procedure to examine the puncture site and grant fit-to-fly clearance. Once home, desk work can usually resume within one to two weeks, while heavy lifting and strenuous workouts should be avoided for three to four weeks.
Risks and potential complications of vertebral artery stenting
Every endovascular intervention carries potential risks. Health organisations including the NHS and the American Heart Association advise that vertebral stenting should only be performed by experienced neuro-interventionalists in fully equipped centres. Understanding vertebral artery stenting risks enables patients to make informed choices.
Possible complications include:
- Periprocedural stroke or TIA: Catheter manipulation may dislodge microscopic debris into downstream brain vessels.
- Arterial dissection: Balloon inflation or stent opening can rarely cause a small tear in the inner vessel lining.
- Cerebral hyperperfusion: Rapidly restored arterial flow into chronically restricted brain vessels can trigger headaches or swelling if blood pressure is not strictly managed.
- In-stent restenosis: The vessel wall may form scar tissue inside the stent, causing gradual narrowing in 15% to 25% of cases.
- Puncture site haematoma: Bleeding or bruising at the groin or wrist entry site, typically resolving with local compression.
- Contrast reaction: Temporary kidney strain or mild allergy related to the iodinated contrast dye.
How to choose a neurovascular centre in Turkey and red flags to watch for
Neurovascular stenting requires specialised medical infrastructure. Major academic hospitals in Turkey that carry out complex neurosurgical operations—from vascular stenting to skull base procedures like transnasal resection of tumor—offer fully staffed intensive care units and 24-hour imaging support. Review our full directory of neurosurgery treatments in Turkey to understand facility standards.
When researching hospitals, verify these essential standards:
- Advanced catheter lab: The hospital must possess a modern biplane digital subtraction angiography suite dedicated to neurovascular work.
- Specialist credentials: Your procedure should be performed by a certified interventional neuroradiologist or endovascular neurosurgeon with extensive vessel stenting experience.
- On-site neuro-ICU: Never undergo arterial stenting in a facility that lacks an on-site, fully staffed intensive care unit.
- Red flag — Guaranteed cure: Avoid clinics that promise complete stroke immunity or claim the procedure carries no risk.
- Red flag — Stenting without prior medical therapy: Be cautious if a clinic recommends immediate stenting for mild or non-symptomatic narrowing without exploring medical therapy first.
Essential questions to ask your specialist before treatment
Before confirming your trip, discuss your diagnosis directly with your clinical team. Useful questions include:
- What is the measured degree and exact location of my vertebral artery narrowing?
- Why is stenting recommended rather than continuing with medical therapy alone?
- How many vertebral artery stenting procedures does your interventional team perform annually?
- Will the catheter access be through my wrist or my groin?
- What type of stent do you recommend for my arterial anatomy?
- What specific blood-thinning medications will I need to take after the procedure, and for how long?
- What follow-up scans will I need once I return home, and when should they be scheduled?

Frequently asked questions
Vertebral artery angioplasty and stenting is an endovascular procedure to treat severe narrowing in the vertebral arteries, which supply blood to the brainstem and cerebellum. A specialist inserts a catheter through the wrist or groin, inflates a miniature balloon to compress plaque, and places a permanent metal stent to keep the artery open, reducing the risk of stroke.
Yes. Technical success rates exceed 95% in restoring blood flow through narrowed vertebral vessels. Randomised clinical trials show that stenting is especially effective for patients who suffer recurrent transient ischaemic attacks or stroke symptoms despite taking antiplatelet medications and statins. For patients without symptoms, intensive medical therapy alone is generally preferred.
In Turkey, vertebral artery angioplasty and stenting generally costs between €4,500 and €9,500, compared with €11,000 to €22,000 in the UK and higher in the US. The price varies depending on the stent model, arterial access route, and intermediate care duration. Packages typically include diagnostic angiography, hospital stay, medications, and transfers.
Before and after results are evaluated via digital subtraction angiography, CT, or MRI rather than physical photographs. Pre-procedure scans show severe arterial narrowing with delayed posterior cerebral perfusion. Post-procedure scans confirm immediate widening of the vessel lumen and normalised blood flow. Clinically, successful treatment stops recurrent dizzy spells, double vision, and drop attacks.
Hospital recovery usually takes one to two nights, including 12 to 24 hours of close monitoring in high-dependency care. Bed rest lasts four to six hours if femoral access was used, or less for radial access. Most patients return to light activities and desk work within one to two weeks, avoiding heavy lifting for three to four weeks.
The procedure is not painful because the arterial puncture site is thoroughly numbed with local anaesthetic, and mild sedation keeps you calm and comfortable throughout. You may feel brief pressure or warmth during contrast dye injections, but blood vessels do not feel pain. Afterwards, mild soreness or bruising at the puncture site resolves within several days.
Vertebral artery stents are permanent medical implants designed to keep the artery patent indefinitely. In roughly 15% to 25% of cases, scar tissue can gradually narrow the stent (in-stent restenosis) over the first year. Long-term patency depends on strictly adhering to prescribed dual antiplatelet medications, taking cholesterol-lowering statins, and controlling blood pressure.
The procedure is relatively safe when performed by experienced neurovascular teams in accredited hospitals with neuro-intensive care facilities. Extracranial stenting carries a lower risk profile than intracranial stenting. Potential complications include periprocedural TIA or stroke, arterial dissection, puncture site haematoma, and cerebral hyperperfusion, which is minimised through rigorous blood pressure management.
Intensive medical therapy—using antiplatelets, high-dose statins, and blood pressure control—is the first-line treatment for all patients with vertebral narrowing, especially if asymptomatic. Vertebral stenting is reserved for patients whose symptoms persist despite optimal medical therapy. Stenting mechanically opens the vessel to restore blood flow, whereas medical therapy stabilises plaque without widening the lumen.
Plan to stay in Turkey for five to seven nights. This allows time for pre-operative consultations and imaging, the endovascular procedure, one to two nights of hospital observation, and a follow-up assessment four to five days later to confirm the puncture site is healing well and grant fit-to-fly clearance.
