Can neurosurgeons treat brain aneurysms?

A brain aneurysm is a weak spot on the wall of an artery in the brain, which can balloon out and — rarely — rupture. Not every aneurysm needs treatment; many small, stable ones are simply monitored.

When treatment is needed, there are two options. Endovascular coiling (or newer techniques like flow diversion) is performed by an interventional neuroradiologist through a small catheter in the groin. No incision on the head is made. This is now the first-line treatment for most aneurysms.

Surgical clipping remains the right choice for certain aneurysms — particularly larger, wider-necked ones and those in specific locations. It involves a craniotomy and placing a tiny titanium clip across the neck of the aneurysm.

Which one is right depends on the aneurysm's size, location, shape and your overall health. This is always a joint decision between the neurosurgeon and the interventional neuroradiologist. If you are diagnosed with an aneurysm, I will make sure both options are considered.

A ruptured aneurysm is a neurosurgical emergency. Anyone with a sudden, severe "thunderclap" headache — the worst of their life — must go straight to a hospital with neurosurgical services.
