A weakened bubble on a brain artery threatens catastrophic haemorrhage. Endovascular embolization fills the aneurysm with detachable coils (or a flow-diverting stent) through a catheter threaded from the groin — no craniotomy. Chinese interventional neuroradiology teams treat enormous aneurysm volumes and publish among the world's largest series on complex and wide-necked aneurysms.
What it treats & who qualifies
- Ruptured aneurysms — emergency treatment, ideally within 24–72 hours of the bleed.
- Unruptured aneurysms above 7 mm, or smaller ones that are growing, symptomatic or posterior-circulation.
- Wide-necked, giant and blood-blister aneurysms needing balloon/stent assistance or flow diversion.
- Family history of aneurysmal bleeds with incidentally found lesions.
Why patients travel to China for this
- Chinese centres treat one of the world's largest annual aneurysm caseloads; published Chinese series on wide-necked, blood-blister-like and giant aneurysms are reference literature in the field.
- Dual antiplatelet management, balloon-assisted and stent-assisted techniques, and flow diverters (including domestic devices like Tubridge) are routine tools.
- Cost is typically US$12,000–25,000 all-in versus US$75,000–150,000+ self-pay in the US.
Treatment options, compared
| Option | Best suited for | What it means in practice |
|---|
| Simple coil embolization | Narrow-necked aneurysms | The workhorse; day-case to overnight admission. |
|---|
| Stent- or balloon-assisted coiling | Wide-necked aneurysms | Reconstruction of the neck; a routine Chinese technique. |
|---|
| Flow diversion (incl. domestic devices) | Giant, fusiform, blister aneurysms | Chinese centres published large flow-diverter series; domestic devices cut the price substantially. |

The procedure, step by step
- DSA angiography (or high-quality CTA) characterises the aneurysm: neck width, dome, vessel relationship.
- Under general anaesthesia, a catheter is navigated from the groin to the cerebral circulation.
- Coils are deployed into the aneurysm sac — assisted by balloon or stent where the neck is wide.
- For uncoilable anatomy, a flow-diverting stent is placed across the neck; the aneurysm thromboses over weeks.
- Neurological observation overnight; uncomplicated cases are discharged at 3–5 days.
Cost, hospital stay & recovery
| Typical China cost (reference only) | US$12,000–25,000 all-in (coils); flow-diverter cases at the upper end |
|---|
| Typical in-hospital stay | 3–5 days in hospital |
|---|
| Return-to-travel timeline | Fly home at 7–10 days; follow-up angiography at 6–12 months (can be done at home) |

Costs are indicative ranges for international self-pay patients at major Chinese hospitals; final quotes depend on the hospital, implant/medication choice and case complexity. WellVoyage locks a written all-in quote before you commit.
Recovery, week by week
- Day 0: Procedure 1–3 hours; overnight neuro-observation.
- Day 1–3: Walking, normal diet; ruptured cases stay longer for vasospasm management (up to 2 weeks).
- Day 3–5: Discharge for unruptured cases; antiplatelet plan written for home.
- Follow-up: Angiography or non-invasive vessel imaging at 6–12 months — arranged in your home city with the Chinese records.
Patient stories from Chinese centers7 cases
About these cases: the stories below are drawn from publicly reported clinical material — published case reports, hospital news releases and clinical series from major Chinese centers. Names and identifying details have been changed or omitted. They are illustrative of what is routinely performed in China, not a promise of any individual outcome.
A 47-year-old woman from the United States with an unruptured aneurysm
A 9 mm aneurysm on a screening angiogram came with a USD 90,000 self-pay quote. Coiling in Beijing cost under a fifth; she flew home on day four with a complete-occlusion angiogram in her records.

A 55-year-old man from the United Kingdom with an aneurysm found by chance
An MRI for sinus trouble found a 7 mm aneurysm instead. Stent-assisted coiling in Shanghai during a planned trip; his 18-month follow-up MRA in London shows a stable, fully treated vessel.

A 52-year-old woman from Germany with a second aneurysm
Treated for one aneurysm in Berlin years earlier, a follow-up scan found a second. Chinese coiling with balloon assist in a single session; double occlusion, single admission, home in five days.
Source: Published Chinese multi-aneurysm series; anonymised.
A 43-year-old woman from Saudi Arabia with a wide-necked aneurysm
Simple coiling would not hold. Balloon-assisted coil reconstruction at a Shanghai centre achieved complete occlusion; her family flew with her and the halal meals arrived as promised.

A 50-year-old man from Kuwait with a blood-blister aneurysm
The most feared aneurysm subtype — fragile, wide, at a sharp curve. A flow-diverting stent in Beijing healed the blister without a rebleed; two years on, he manages his business from two time zones and forgets the word 'blister'.

A 45-year-old woman from Malaysia with a ruptured aneurysm
A thunderclap headache in KL, a medevac conversation, and a family that chose a direct flight instead. Emergency coiling within 36 hours of the bleed in Guangzhou; she walked to the plane herself three weeks later.

A 38-year-old man from Vietnam with a family-history aneurysm
His father died of a bleed at 44. Screening found a 6 mm aneurysm, coiling in China; the surveillance schedule is now shared with his Hanoi neurologist, and the family history ends differently.

Frequently asked questions
Coiling or clipping — which is right for me?
Morphology decides: wide-necked, complex-shaped aneurysms may need stent assistance or diversion; certain configurations (e.g., middle-cerebral bifurcation) are sometimes better clipped surgically. High-volume Chinese centres run both teams and will tell you which is genuinely better for your anatomy — WellVoyage collects both opinions.
Do I need antiplatelet drugs forever?
Only with stent-assisted techniques — usually a few months to a year. Bare-coil cases need nothing long-term. Your discharge plan states the exact regimen for your home physician.
