What is Aneurysm Clipping?

Microsurgical clipping places a small titanium clip across the neck of a brain aneurysm, permanently isolating it from the cerebral circulation. It is the definitive durable treatment for ruptured and unruptured aneurysms in suitable anatomy.

Why China?

• Tiantan Hospital: Asia's largest neurosurgery center — 3,000+ aneurysm cases/year
• Cost: $14,000-$22,000 vs. $60,000-$120,000 in the US
• ICG angiography standard: Real-time vessel patency confirmation
• Complex aneurysms: Bypass + trapping for giant aneurysms at expert centers

Who is a candidate?

• Unruptured aneurysm ≥7mm or with high-risk features
• Ruptured aneurysm (SAH) suitable for surgical access
• Complex aneurysms unsuitable for coiling (wide neck, branches)
• Failed prior endovascular treatment

Outcomes

Complete occlusion: >95% (durable lifetime). Mortality unruptured: <1%. Mortality ruptured: 5-10% (depends on Hunt-Hess grade). Recurrence rate: <2% at 10 years (vs 10-20% coiling).
