NewYork-Presbyterian Hospital's doctors can determine the best treatment for each patient with a brain aneurysm by considering factors such as the patient's age and overall health and the size, shape, and location of the aneurysm. Available treatment options include:


Surgical clipping

Surgeons place a tiny metal clip at the base of the brain aneurysm to seal it off from the normal blood supply and to prevent it from growing or rupturing.

Endovascular coiling or embolization

In this minimally invasive approach, surgeons fill the cerebral aneurysm with tiny platinum coils or a "super glue" to promote the aneurysm's healing and to eliminate the potential for future rupture.

Extracranial-intracranial bypass

Doctors may combine surgical and endovascular approaches to treat large and complex brain aneurysms. With this relatively uncommon approach, doctors first reroute the blood flow around the aneurysm, then treat it with clipping or endovascular embolization. This approach combines two complementary procedures to ensure the safe treatment of these aneurysms.

If the aneurysm is located in or near critical areas of the brain, doctors may also use special brain mapping techniques to approach delicate areas of the brain with great precision and to avoid injuring the brain during surgery.

Robert A. Solomon, M.D., F.A.C.S., the Chairman and Director of Service of the Department of Neurological Surgery at NewYork-Presbyterian/Columbia University Medical Center, discusses the two different approaches doctors utilize to treat cerebral aneurysm.

In some patients with aneurysms that are not causing symptoms, particularly those that are small (less than 5 mm), doctors may want to observe the patient rather than perform surgery, because the risk of rupture from small aneurysms is often low and surgery for a brain aneurysm may carry some risk. In such cases, our physicians assess patients regularly with imaging studies to make sure the aneurysm is not growing.


Researchers at both NewYork-Presbyterian/Weill Cornell and NewYork-Presbyterian/Columbia are leading the search for new, more effective ways to treat aneurysms. Patients have access to clinical trials of innovative approaches and devices.
